How much lighter

[lwilde.0422]

I can't remember exactly, I will post it up next week when I get back in the shop. It's pretty significant about 330 grams or roughly 3/4 of a lb.

[lwilde.0422]

New pics posted in first post.

[Krazymaan]

I will take ONE.

[lwilde.0422]

Done! Who else wants one? Shipments will be going out this Thursday.

[graynester]

what all comes in the kit

[lwilde.0422]

Comes with the 1/4" plate and hardware. Not the whole flywheel

[graynester]

whats the outside measurement like 8.75"

[lwilde.0422]

whats the outside measurement like 8.75"

Yes

[Krazymaan]

I'll take the other one too.

Thanks

[lwilde.0422]

4 Sold... These are an awesome performance AND aesthetic mod for the price!

[lwilde.0422]

Shipments going out this Thursday if anyone else wants one.

All packaged shipped and tracking numbers sent! let me know if any of you have any questions. All packages should be arriving by Monday.
Next shipment will be Thursday the 16th of March.

[CNC_Guy]

How many rpm will these handle?

[lwilde.0422]

Great question! I have a customer putting one on a 10k rpm Jon Wright motor. Here's the thing, it's stronger and lighter than the stock steel. Dropping just under 1lb of mass rotating 10k rpm is a HUGGGGG difference!!!! You won't break this thing with RPM

[proprider]

Is that the part that is referred to as the flex plate?

[lwilde.0422]

Not sure I would call it a flex plate. Flex plates are between a motor and a transmission. This is just a free spinning plate

I have one of those motors too. :)

It is a flexplate

[lwilde.0422]

In your experience where were they breaking? What was the failing point?

[lwilde.0422]

Some evidence or something supporting your claim would be great after that bash...

I also find it VERY hard to believe someone did this with 1/2" 6061... Actually, I plain don't believe it at all

I will retract my previous post which was derogatorily speculative.

I work with high-speed rotating machinery, but for this application maybe sfi standards would be a starting point for comparison:

http://www.sfifoundation.com/wp-content/pdfs/specs/Spec_29.2_082616.pdf

SFI standards indicate that the flexplate should be balanced by the manufacturer and spun to 12.5-13.5K RPM for 15 minute intervals until a total of 1 hour run time has been achieved. The part is then to be dye-pen or mag-particle inspected for signs of cracking.

Test bars are also to be broken from the parent material to determine its suitability.

You stated that you are using 6061 aluminum, so looking at the specs:

sfi calls for 35,000 psi min yield strength, 42,000 psi min yield strength and 8% min elongation.

6061 specs call for 40,000 min yield strength, 45,000 psi min yield strength and 12% min elongation.

The only possible issues that I see are balance related and a possible lack of testing. As you are not selling an assembled flywheel, you have no control over the balance of the final assembled unit.

It's probably ok for what most guys are going to do with it. Maybe better than stock. Sure does look cool...

[Krazymaan]

I still like it :)

[lwilde.0422]

"it's probably ok for what most guys are going to do with it. Maybe better than stock. Sure does look cool..."
-Thanks for the helpful information and for supporting your claim!

Krazymaan thanks for the comment as well! Your going to love these plates.

I have been getting bashed by some big names on this site. And none of them have given ANY supporting evidence to their claims. NONE!

These same people also are bashing other members and if this continues I will post these comments for everyone to see.

For my customers- if you have any problems with these plates let me know. I'm not trying to rip anyone off here. I make $17 on each plate I sell at the full price of $150. This is not a capital gains venture for me.

[lwilde.0422]

I can believe that, 1/2" aluminum is far to thick and therefore way to heavy for this application likley cracking under its own weight. 1/2" will not flex enough to withstand the constant vertical forces exerted on a bouncy race boat. 1/4 " with relief holes should.

By the way RBT, I find it very interesting you and Chris Carson both bashed me (and other members) and just minutes after I spoke with him.. regarding the same Seabold wheel.. I'm sure it just coincidence though.. funny thing too is Chris wanted one of my wheels

[lwilde.0422]

Then can you please rephrase your delete your earlier comment.

Thats an Sri regulation for a flex plate on an. Auto trans , which has you know a Torque converter bolted to it, never seen one of those on top of a Merc outboard.

So different specs of course would be required.

These we should be fine for what they do

[90 5.0]

Also I used to be a level 3 NDT(Non destructive testing) tech for many years, I have experience in die pen, mag particle , x-ray and ultrasonic testing.

If anyone wants to run one for a while and send it to me I'll do a complete die penetrant test on it for free. Just send with a return shipping label.

[lwilde.0422]

That would be great! Anyone of my customer who wants to send theirs in let me know I will PayPal you the shipping funds.

Obviously, it would be thought of a biased if I send mine in..

I am aware that it is for a flex plate on an auto trans, but there is no standard for comparison in the marine world. Different specs may well be required, but the SFI spec is at least a starting point from a similar application.

An auto trans flexplate has a hub that is attached to the crankshaft flange at its ID, and a ring gear for starting at its OD. There is a spec there for a similar part, tested to a similar maximum speed.

The SFI rotational test only includes the flexplate, engine block, and a "suitable containment chamber to protect test personnel." The flexplate is driven by a spindle. The crankshaft and torque converter are not part of the equation. I would think that a similar testing protocol would also be suitable for the outboard application.

In high-speed rotating couplings, the bolts are supplied in weight matched sets. Depending on the tolerance of the provided bolts, the tolerance of the original Merc bolts, and the tolerance of the original balance job, there is a potential to end up with a poorly balanced end product. Will it make a difference in longevity? Anybody's guess without some hard data.

If the Merc bolts weren't weight matched, and the flywheel was balanced after assembly, that leaves the biggest potential for an imbalanced assembly. The odds may be in favor of assembling something without a gross imbalance, but again, more hard data may be necessary to know for sure.

Again, probably ok for what most guys are going to do with it, and it sure does look cool!

Stand up offer, also great to see guys making aftermarket parts for these motors! This is what is going to help keep this hobby alive!

[Krazymaan]

Mine is going to be balanced. I wouldn't want to decapitate the clown behind me. :reddevil: Or would I?

[Krazymaan]

What a coincidence, I really am going to be putting it on my Jon Wright motor. I'm hoping for the huge difference version, not really a hug kind of guy.

[Krazymaan]

Got my flywheel tops today, Looks great. I'm gonna have to laser etch my company name in them and say I made them. ;)

[Schramer]

I got a little bit of incite from another thread that, combined with this one, is making me a little bit confused....I haven't seen anyone bash you, or any other members at all!? You say something about these comments possibly "being posted for everyone to see" which means you have some kind of information/discussions that have either transpired in PRIVATE, were intended to be PRIVATE, (or got deleted from this thread that I haven't seen) and that you may bring them out to the public that were never meant for the public in the 1st place, why?? Do you think that these (BTW, well respected) people on this site just got here yesterday and start fights & mess with people for fun???? Do you have any clue how hard it is to even get, yet alone maintain, a good reputation on this site is with all the people now-a-days that trash anybody at the slightest "whatever" comment that comes from them.....especially when these EXPERIENCED guys also come on here to help the common good, not hurt it!?

Look.....I think that what you are making/selling here is a piece that could possibly help and/or make a LOT OF PEOPLE on this site -or possibly beyond this site- really happy with a simple mod to a motor that would help them get a step closer to their goal is great....and I'm all for it!!!! But, regardless of what these people supposedly said to you, I personally haven't seen any testing results, a disclaimer saying this is an "untested unit" that needs to be balanced again after assembly, or anyone that has even technically ran this mod over 8k (let alone for a period of 20+ hrs in rough water), makes me (as a consumer) very nervous. Then... when you start stating things (like you have) in order to take away people's credibility, of which some of the highest respected people that have been on this site waaaaay longer than most of us with reputations that continue to grow, and throw them in the garbage like they were yesterday's news is ludicrous!!!! These guys stand in line to help people like us and our drive to go faster & often most of the time they don't get a friggin dollar from it, and then turn around and spend their own money to support the very site you bash them on!!!! For that matter, I would have to definitely assume that you do not own your own business.

They were here before many of us joined..... and they will probably be here after many of us leave too. All I hope for is that most the people in the middle of this all check their ego at the door and listen to some of these people from time to time.....they may end up like me and learning more that they ever could imagine, and eventually wanting to stick their foot in their mouth for chit they said before they sat down and thought about it!!! Many have humbled me in my time :thumbsup:

[lwilde.0422]

Thanks Krazymaan! Really glad you like them. Please post your review once you get her running! Pictures are always awesome too:thumbsup:

[graynester]

the plates do look nice.

well said schrammer
i don't know much but i'm going with flex plate:cheers::iagree:

ps the wisdom on this site on hull design, history and outboards is second to nun, due to the engineering and testing.... and retesting.... and rerunning parts and theory's making them proven.

without this site, a guy like me would not be able to own, run and keep my own stuff going.

thanks to this sight and its knowledgeable members for bringing hi-po boating into my life!

looks like a nice piece. B

[lwilde.0422]

Schramer- Thanks for the post. Having reciently separated from serving my country I know the difference between humility and disrespect.

No doubt, I have eaten my own words in my day. After a long conversation with Chris Carson on this subject, I understand where you are coming from as well. So again, thank you for the post and words of wisdom.

On the other hand, I sold out of plates faster than expected. So far I have recieved only GREAT reviews. Tests are being done and I have requests to build these for other motor applications as well.

I am a DEVOUT PATRIOT so I thank you for your service to this beautiful country of ours!!!!! I'm also very glad you are selling these like hotcakes and hope the best for you!

That being said, you have not addressed the issues of detailed testing, any kind of notes to the balancing of this unit after assembly, or proof to the people that are buying this product will have a reliable AND SAFE piece that will hold up to the abuse some people put their motors through.

I still think it is a great idea but if an aluminum top plate for a high perf/high rpm motor was a viable weigh savings option, the big corporations would have done it a long time ago.? I personally saw a high perf flywheel come apart at Jasper one year that ate the entire top of the motor and cowl apart. These things could be compared to a shotgun blast or a hand grenade with the amount kinetic energy involved with one spinning north of 10,000 rpms! This is all I'm going to say on this matter....I have spoke my peace bud.

Schramer

[lwilde.0422]

Schramer- Thank you for the post. I have stopped selling these plates. More testing is being conducted, by a 3rd party, before any more will be sold.

[powerabout]

13,000 rpm and move the spinning axis at the same time

[Schramer]

Schramer- Thank you for the post. I have stopped selling these plates. More testing is being conducted, by a 3rd party, before any more will be sold.

I will make no claim to being the person who knows it all, nor that I am an expert to anything!!! I have seen quite a bit of chit go down on this website and YET to see someone, like yourself, handle a particular situation in the manner of which you did this one my friend!!!

I'll tell you what.....I look forward to the testing & results and will stand in line to help in any way I possibly can, seriously!!!! If the results show that this is a viable way to step one's game up, I will be the next person in line to purchase :thumbsup::thumbsup::thumbsup:

[nitro_rat]

Schramer- Thank you for the post. I have stopped selling these plates. More testing is being conducted, by a 3rd party, before any more will be sold.

lwilde, do you have any updates on testing on your flexplates? Anybody spin one of these up on a motor yet?

Inquiring minds want to know!

[lwilde.0422]

nitro_rat- there are several people on this site who have them. I have not had any feedback yet. I run one on my stock 2.4 turning 6100 and have not had any issues. I ran into a problem with the testing not being able to be completed.

If anyone has the ability to spin one of these let me know I will send you one.

I stopped selling these because I received alot of criticism from various individuals on this sight. Maybe they are right, maybe they are wrong, I don't know. I spoke with an individual in WA who builds race motors and is on the board out here, he said it will work as long as you run it with the upper and lower flex washers.

But as of right now, I have not received, nor had any negative side affects with that's plates.

And they look super cool!

[.william1945]

I will take one also

[lwilde.0422]

These are "untested" I do not guarantee anything.

[Krazymaan]

I put mine on the flywheel put it on the lathe and spun it to 6k and it was perfect. Didn't balance it yet but it sure was true.

Thank you Krazymaan! Post up some pics when you can!

[powerabout]

Its the gyroscope effect that causes the issues

[Krazymaan]

Will do

[josh pomerleau]

humm intersting I will take one also 407 535 0089 :rolleyes:

[lwilde.0422]

No longer available. Further testing required. If you have one I recommend waiting to use it until further testing is available. Thanks S and F.

[Krazymaan]

Hopefully I will get some 8k plus time on mine this weekend. Unless its raining again. I'll keep you posted, maybe a video if possible.
Now if i can just remember who was making those lightweight high performance nylon wing plate bolts, I'll have it made.

[Krazymaan]

lwilde
Just thinking out loud here but Its funny how your being attacked by just a few people and the rest are perfectly happy. Sounds like your running for President and Hillary and her gang are on the rag. Like this Josh Clown. what a retarded statement. Mail Fraud, good lord. Instead of screaming mail fraud, I want to know what the mail fraud is, seriously, If he's gonna accuse you of mail fraud in public, he can at least have the balls to say what the mail fraud is. What a coward. Apparently he has to rely on his friend who can text and a few scream and fly members that jumped on the bandwagon to do his thinking for him.
I'm going to go out on a limb and say you need to have your discs tested, So, you need to contact the aliens, because they are the masters of the flying discs. Once the bandwagon gets rolling, it never stops. This will drag out for years until you get tired of it and just delete this entire thread, which you can.
As far as you being bashed by members that don't even have one. Sounds typical.
As far as members that produce items and especially the members that perform services, maybe every time they shave a head down, they should have the newly head tested for safety, you did remove material, which has weakened the structure, not by much but it did, now you have less material which means the head has thinner material which can result in a hotter motor or easier warpage. Where is the testing, the comparison charts on strength.
I bought a black composite 1" spacer. It comes with the cheesiest crappiest allen head bolts I ever saw. I had to replace them during installation they were so bad. What if they broke during a back fire and blew the carbs and plate right off the motor and hit a back seat passenger, where is the testing before selling such an item with low quality fasteners, thats where the strength needed to be?
How about anybody that alters engine parts, any parts, these folks aren't being held under a microscope like lwilde is. They all act like their modifications holds up to anything but yours won't, them is bandwagon wannabe's. Lightened rods can break and blow a block chunk right out and kill someone, so can any motor modification. Where is your guarantee and test sheets that should go along with these items.
I just find it insane that its your turn. Lets just hope nobody ever sells homemade wing plates ever again, eh.
Texting, gotta love it. Never talked to a sole.
Engineering, please. The entire modified non factory/oem engine world is all a gamble, it works, it don't work, it breaks, it don't break. Every engine modifier has copied some companies basic engineering plan and modified it to suit their needs or what they think might be an improvement without getting their improved product engineered which you can't because its wasn't your design to begin with. With enough whining like this SnF might just have to ban the sale of any product or service other than oem that doesn't provide an approved engineering certificate by a third party testing facility for safety reasons. or the other version would be, shut your pie hole and just don't buy what you don't want.
I also noticed that a few big mouths have deleted their negative postings. Good for them, they should have never said anything.
Everyone who sold an altered lower unit had it tested by a third party so nobody gets injured, right? Thats what I thought.

[lwilde.0422]

Thank you for the support Krazymaan.

I really hope the next person who does business with Josh has a better experience. He verbally threatened my life though text messages and after several attempts to ask him to please stop harassing me I had to call Verizon to have his number blocked from my phone. I tried to make it right with Josh, but he is just really rude and demading like an over entitled child.

To preserve this great site and reduce drama I have pulled the sales of these plates. This was not a capital gains venture for me, infact I haven't even sold enough to breakeven for all the prototypes I made just to make them fit so perfect.

Thanks again scream and fly. Regardless of the threats I still appreciate this site and the people it who share here.

[outasite]

Another nail in the coffin,whiners win.What was being offered was a"part of a rotating assembly" any fool knows that when you change a piston or rod in a balanced engine it is no longer "balanced" IMO due to the size and shape of the part it would be very unlikely to effect the overall balance.Hell I sent six Merc 260 flywheels out for balance,three were very close one was so so and two were way out! A lot of these have had the hubs,ring gears, replaced or been apart and not indexed properly.So don't assume when you buy a used Merc one it's good for 10000 RPMs.Point is,you were being offered a PART! It's up to you to decide weather to use it,or lose it.This guy was not out to get rich,he was trying to help our sport.---btw if ya decide later to sell a couple "parts" pm me.Bob

[whipper]

Well just read the whole thread something I rarely do! haha My hat is off to you Lwild I think what your doing the world need more of!! People trying to make some bread doing what they love doing. Remember this. There are always people who will try and keep you down! No one wants competition and everyone gets jealous when someone can do something better and cheaper than them! Every innovator that has been successful has had to endure these rants and rages so keep on doing what your doing because I for one am very interested in the things your doing. That said then statistically there must me more you just haven't heard from. Also agree with the testing part of things makes sense and your du diligents seems perfectly correct as what your doing with these {flex plates} until further testing. Like some have said its a part that might need balancing depending on how high they want to spin them. Sounds like you have guys willing to help ya in that department also. Your machine work looks awesome!! i cant wait to try those T stat washers you made they look so sweet!! R&D and innovation good for you!! Keep it up you'll do great things with your common sense and great work! You should have a company name and get a supporting vender membership for hear. Theres tax and intensives in doing so also? If you get that R&D down for your products a bigger name might want to help you sell them with more volume? Tool up there bud I like {LOVE} the looks of your workmanship . i see what some mean on testing just a small stumbling block. Im sure with your attitude you can make your products pass the tests to put everyone at ease . Gota start some were!! :cheers:

[lwilde.0422]

Thanks for your comments and compliments. I really appreciate the support. You are correct. I will, and have, received both great support and then absolute insults and threats. They have not stopped me yet. There is alot of room for innovation in this community. Most of us are running parts made before 1995. That was 22-years ago! You will love the transition from your current T-stats to the ones headed your way now. Once I get testing completed on these plates I will repost them. Thanks again Whipper!
