Reeds

[Tony Brucato]

Any of us that has run a proper dyno setup knows the value of proper testing. All of the testing parameters have to be kept at a absolute constant or the testing results are misleading. Also one of the testing parameters I do not see in a lot of dyno runs or even water testing is the exhaust gas temperature. Having the EGT exactly the same on every test is essential to a correct test. If one brand of reed flows more than another the jetting requirements change. If a brand of reed richens the fuel/air ratio and the exhaust temp drops you will have less horsepower. Re-jetting to get the same exhaust temp,(fuel/air ratio), that testing parameter is now correct and will result in a correct test. <O></O>[/FONT][/COLOR]
[COLOR=black][FONT=Verdana]The biggest issue is that there are a very few of us that have access to all the proper equipment and testing facilities. Deliver a perfect motor combination to the end customer in a different location,(altitude, water density, air density, etc), and the end results change. Then they tune on it as time goes on. I can not tell you how many delivered motors, (short blocks), that customers complain about not being as fast as it should be, that I have had them drive over and install it on the dyno and readjust what they have done to get back to the same Horsepower figures. It takes a large amount of time, money, knowledge, equipment, driver ability, and setup to get perfect package. The second you get it something else changes and you are on the trail again

I agree that fuel delivery will have to be optimized for each type of reed.
Thanks for the insight, Tony!

I'd love it.

I'd ask that a baseline be determined with stock reeds first and stock reeds retested at the end to show nothing changed (wear in, etc) and that the dyno's results are really tight.

There is a chance that we would all learn something. Education is a good thing.

One last note:
If you test 5 brands of a product and you post the results, you will have 1 friend and 4 enemies. As well as all their followers. The main issue is that most of the comments are from the average Joe that has not had the privledge of having all the knowledge, & testing equipment.


It takes a lot of guts to post results knowing that you are standing in the flack zone. Trust me I have been in the Flack zone many times.


Good job, Test away, looking forward to the results, and if you need any information at all, please contact me direct.

[Mark75H]

Its also possible to have 5 enemies

[TDR_50]

This is true.

Learning is a never ending process.

Al, this "controlled" testing can be very helpful in choosing proper reeds for an application. My "dinosaur" testing methods are for nitrous use only and proir to actually trying a set of TDR's I was using "home made" reeds (we already knew what material and thickness worked). From Dec 2008 till August 2009 I ran the same set of TDR's without a glitch (they still look good after being hit with a bunch of nitrous) and wanted to try Carson's reeds. So far the Carson reeds are holding up well under the same harsh treatment that the TDR's went through.

I agree, and I was warned of this from some very knowledagble racers/engine builders when I first started racing. My ass got tore up quick by the hungry alligators that have nothing better to do than talk chit but I keep on testing and blowing **** up.

I keep on testing and blowing **** up.

That's the way I like it

Also What other brands are going to be tested. So far we have:
Stock reeds
Chris Carson reeds
TDR Reeds
??
Lets hear some other brands.

I think Boysen reeds both the racing version and the standard version.
Keeping that in mind:
Standard long life reeds should all be grouped in 1 catagory and ultimate performance reeds in another catagory.

Question #1 is :
Do you want the best performance and they will last only 1 race day.
Do you want good performance but less HP and they will last for seasons.??

Both are available from all the vendors.

Tony brings up a good point as to usage. This is the reason I would like to do it this way, tell the manufacturer its use and expected life as a customer would and take that manufacturers recomendation and test it. The one problem with doing this on an omc is the time needed to change them out, this means the test will take a couple days. While we can control things to a point we will need to rely on the dyno weather station for proper correction factors, it may also mean testing days apart to keep the factors inline. Keep in mind this is a follow up test I dont have time to test every available reed.

Al, you may be walking into a hornet's nest, but I would sure like to see your results.
I also have a test mule for you just sittin here!

(I'm sure I already know the answer to that)

[bigbore]

I can already tell u number 5 (with the dip tube in it),needs 2-b up 3 (on jets),number 1 up 2.

[spirit5.6]

I would rather read a post (if there is not already one??) on how to build a RELIABLE 3.0 with 300 + hp on pump gas as we know Al is pretty much the best at it..
Sorry to disrupt the post
I beleive aslong as you stick with the main brands of reeds, you aint going to see any noticable improvment over each other..

I've always had a hard time getting the Boyesens to last. The CCM reeds have been very durable in my motor and they have picked up a little RPM on my motor when comparing new Boyesens to new CCM reeds.
After they each have a couple of hours of high RPM use however, the Boyesen's performance seems to drop off from wear, chips, or fatigue.

Isn’t that the truth!
Because of chipping, I have been using G10-FR4 and had custom sets cut for The evolution and Taylor cages due to the proprietary sizes in their designs.
Actually numbers from an automated Dyno would be yet another Gift from the Gurus! Thanks again Al!!

Let's go,geT'r done.
