Capt.Insane-o , need your opinioin!!!!

I have started a tuber engine. I sacraficed a block that I had that would need a lot of work so I could find my angles to cut for tubes and finger ports. This is the actual block I will be using and this is what I have so far on my project......

I am using 1/2 copper tubing that has a OD of 5/8" and ID of 1/2". It cuts a little of the side of the sleeve but it is still around .125 thick. I see now why the 2L bored to 2.4's have problems, the lower portion of the sleeve is a lot thinner than the top. I used a 5/8 ball end mill and had to hand blend in the cylinder which did not take long. The tubes fit very snug and don't use much epoxy. I used less than a 1 oz of Marine-tex to install all 6 tubes. I have around 3 hrs total in the tubes and 3.5hrs in the finger ports. After I bore this block I will hand raise the 3/8" finger ports to 2.100. I will smooth out the epoxy and unless you know what to look for, you won't know they are there!!!!:D:D:D

Looks good! Yes it's a ton of work and chips everywhere, cut the finger ports all the way to the bottom of the sleeve. I was bored (pun) and staring at another block this very afternoon actually. They go like ****ing stink when everything is right in the end too. You won't believe it's a 2L.

[wrechin2]

I will cut them to the bottom on the next one. I am ordering a long 7/16 end mill to cut the finger ports in the future. Wider and longer! Hell I sound like a woman now!!!LOL!!!!! On the 18CC heads what octane where you running? Blend or pure race fuel?? I will start out with 26CC heads and 93 octane. Then go up from there.

I have to hold off on mine for a few days as all my parts came in to build a E-tec today. Business before mine!!!!

[Capt.Insane-o]

I run 110 with 18 cc's and 98 main jets in a set of wh 22's. One piece plate with a drag tuner. Cut as much off the front half as you possibly can, lighten and stuff the wrist pins. Get a set of wiseco's and have US1 pin them and your good to go. Get a tach that goes to 10 too. :D

woah, this is sweet... can you clarify what you've done? They are additional transfer ports from crankcase to pistons finger ports right? So the stock setup doesnt actually have any transfer port running to the pistons finger ports? just that ?hole/dent? in the sleeve? This stuff really interests me, but i've never even seen one of these things in pieces. Obviously this is for extra power, does it make them run pretty rough down low?

This is making a old 2L use the newer 2.5 technology of behind the liner, in a sense. The fuel has to pass through a port on a moving piston. By adding the tube you staighten the air flow and increase velocity as well. The booster port is the large port in the center and the finger ports are the 2 ports that have been added on each side of the booster port. Basicly I have added 3 more intake ports. It should not effect the way the engine runs down low. Your 2.4L has the finger ports from the factory and the fuel flow is somewhat comparable to a 2.5L. Hope this helps!

[Capt.Insane-o]

They are a bit chuggy off idle, the same mod works great on a 2.4 too.

[wrechin2]

What is chuggy??? LOL!!!

[YELLOWSS]

pretty sweet. i like to see guys thinking outside the box. it all sounds good in theory..more gas, more air, and a straighter shot... sounds like more power to me...

[wrechin2]

US1 (John Marles) had one of these making 296Hp @9600 RPM! So yeah MORE POWER!!!!! Pretty good out of a 121.9 CI engine! I am going to be conservative on this one.

J,

Its cool to see guys doing things like this to the "little" fishin' motors and am pumped to see how this pans out. The down side to this is I'm going to end up wanting to do some of the same crazy stuff to another 2 liter after I said (numerous times I might add) "When I can crack 80 with a "lake boat" layup, full interior, full fuel, and a passenger, I'll be happy and not complain." :thumbsup:

Mine is a lake boat as well.....I am installing it on a gutted boat that weighs around 350~400#. It has no floor in it and everyplace I could remove weight I did. I could still remove a little more out of the top but would not be able to crawl in it. I can pick it off the trailer and the only thing that touches is the bow stop!:eek: This little engine should run well on it. If not, I have 2.4's and 2.5's that will find their way on it! I am still working on the ugly ducklin but here it is.

Hehe....I'm glad I have an idea what it looks like now so when I run into it @ Jasper I'll know better. :D I'm pretty sure its going to hurt some feelings at some point. :thumbsup:

[Capt.Insane-o]

I'm pretty sure its going to hurt some feelings at some point. :thumbsup:

Oh they do. They love to sing, so use a good set of balanced big rods with sps/arp bolts and a early non oiler crank with a small top 260 main cap and bearing. I'll send you the exhaust port dimension I use on one of them later today.

If you see it at Jasper it is only cause it is one of the boat ramps I go to! LOL!!! I am building it to go against some local guys that do this on the weekends for fun.

Thanks! Maybe on the next one! I have a 2L I bored .060 and can't seem to give it away! I may gather up the stuff to build one of the really mean ones out of it! I have everything but the pistons and upper cap. What is the difference with the caps?

[tlwjkw]

james i have a set of big rods bottom guided with SPS/ARP bolts

Yeah and ya need ta keep 'em :eek::D:D

Does MOLY ring a bell :p

JT.............I'll use tha "little" ones.

[laserguy]

Hey there, I have done several just like this and what captain said about getting everything as light as possible. To say the least, I upset EVERYONE! It beat a 2.5 drag on carbs by a whole boat length. This was in 1997 tho! Cool pics

[laserguy]

Mine dumped raw fuel at idle. I had to lean out the idles a bunch. I played with it for a while to get it to really crack. Once she was dialed in, I couldn't believe the difference. I cut .090 off the front and cut a lot on the pistons too. Good luck with that. I had a lot of fun with mine!

[Way2slow on H2O]

James, I built a .060 2 liter (may still have it) and ran the fingers to the bottom, cut the xtra holes at the bottom on the pistons, widened every hole in cylinder and piston, cut 150 off the front, welded and shaved the 7 pedal cages (actually made the cage conform to the crank, you're increasing the intake volumn so much with the tubes I needed as much "stuffing" as I could come up with) ran 1/2" od aluminum tubes welded in, used a 2 liter champ top guided crank, wiseco's, 141 rods cut and balanced, reamed the guts outta the wrist pins (from 110 to 65 grams), did some welding and cutting in the exhaust chest (didn't hog it like the 2 liter champ), bridgeport tuner, BP horn, BP A-40 chip in ECU, 22cc heads, and a 2" spacer plate. Didn't have any power below 7k (maybe due to being too rich) but would scream on my Hydro. We hung it on my Basser with a 22 yammi and what a terd!!! (compared to a 2.5) Get er goin and she'd pull hard.... never had an opportunity to run more than 8900 (ole Hydra Sport couldn't handle the speed, lol) but it would twist 11k easily on the hydro. I killed the lil motor when the nitrous soleniod froze open and sucked down 10 lbs w/out enrichment fuel :mad: (1st test pass with a 200 shot)

[laserguy]

you went more aggressive than I did. although mine was a 2.4 and all i wanted to do is play. mine turned 8800 and was only bumping 118lbs compression, running pump gas. i turned a steel flywheel, but had my pistons were at 385 grams and the little rods at 330 grams. I was running wh20 mercarbs. i hogged out the chest completely tho, a lot like the paul nicols photo on here.

[Capt.Insane-o]

Idle jetting was tricky, but after getting it all worked out it's a little monster for sure. I based mine off a fat block and used the motor John did for a template as it was used up for the most part. Hopefully I can finish up tweaking the 2.4 I did for a friend this spring.

One thing I love about the 2.0's is they sure are happy about running top end for long periods. I spend a lot of time in the 7500-8500 range and have a little over 575 gallons of fuel through this motor and it has'nt whimpered a bit. And there is this behind the liner 2 liter I talked myself into lol..

I ran the snot out of my "behind the liner" 2.0 bridgeport horn motor. It lived at and loved 9500!!! #5 locater let go so I sleeved it, top pinned the pistons, and have it on a stand as a back-up motor in hopes of someday givin it a shot at 1/4 mile with a bunch of nitrous.

[laserguy]

I want to play. I got an old 2 liter was given to me, has a nine ring crank and rotates, would be cool to buzz the river at 6k and hit it to 9 or so. I got the itch now. I personally like to build them as much as run them. And to keep all the big bucks out of my toys! I picked up a cheap vector a few months ago after being away from hot rodding since 99. I wanna make a cool hot rod for summer!

You know the rest of us need some motors too...........

[wrechin2]

to keep all the big bucks out of my toys!

Same here. This one is a "EXPERIMENTAL build" and very low budget. I wil have around $125 in this! That is one of the good things about having all the toys to build toys like the mill and boring bar and having a bunch of spares doesn't hurt either!. I think I am down to 5 2L blocks now. So if this one turns out to be a disaster I will just grab another one and do it a little different.


Thanks guys for all the compliments and ideals! Glad to see this has started the itch again for some! If you think about it, I have added about as much volume as the oil gear passage added to cylinder #2 (which is already filled up). I am going to stuff it pretty heavy and shave as much as I can off. If I cut a ton off I will have to relocate the bleeder valves to the intake. Shouldn't be hard. Had to do that to a 2.4 intake I put on a 2.5.

James your pm inbox is full ill send the block next week early

[wrechin2]

I will delete some! Sorry!!
