So I had the opportunity to finally tune my car on the 'Poor Mans Race Gas' ....aka E-85 and here are the results...

We all know that dyno's are pretty much used as a tuning tool so no need to pollute the thread with your dyno this, this dyno that....its pointless....and since I know most of you are interested in the dealt gains well I started off with a base line pull of the 91 oct tune....

I ran into a bit of a problem when it came to the baseline....and that was the fact that I had tampered with my boost controller @ the drag strip which threw the tune off a bit...after playing around with that for a few pulls getting the boost where it belonged...here is were I sit today vs to the numbers I got on 8-18-08 (The smoothing is set to 5 since that's what most like to see)

This goes to show that even with the same tune, a car that is dyno'ed on different days can produce different results...I believe that the weather had the most to do with the difference in the output...both these pulls were @ 25.5 lbs.....below I have included the conditions of the run file which shows the weather and the correction factor used for those pulls...




Here is my running Mod List...

-Buschur Racing Fuel Rail
-AMS 35R Turbo Kit
-Dejon Tool Manual Boost Controller
-Brian Crower Valve Springs/Retainers
-Cosworth M2 Camshafts
-Tial Blow Off Valve
-AMS Upper Inter Cooler Pipe
-BBK 75mm Throttle Body
-AMS Velocity Stack Runner Intake Manifold
-AEM Engine Management System
-AMS FMIC
-RC 1000cc Injectors
-Megan 3" Catback Exhaust w/resonated testpipe
-AEM Cam gears (+3i/-1e)
-Jackson Auto Machine 'Big Bore' Lifter set
-ARP Headstuds
-Walbro 255lph fuel pump

With all that being said, now to the results....

Due to my limited fuel system (RC1000cc, Single Walbro Pump, and Buschur Fuel Rail) I was only able to run 21 lbs of boost with this setup (compared to the baseline of the 91oct tune done @ 25.5lbs) with a 95% duty cycle on the injectors @ 7.1k RPMs...any more boost and the car would lean itself out since there wasn't enough fuel being delivered...time for a double pumper and bigger injectors, and just when I thought I was done modding...lol!



Here are some boost levels and the figures they produced...

16 lbs @ 384whp and 303 ft lbs....

17 lbs @ 400whp and 312 ft lbs...

18 lbs @ 422whp and 333 ft lbs...

20 lbs @ 460whp and 357 ft lbs...

Leave your comments and/or questions on the way out.

 

Nice on 21psi! Id be happy with that!

 

Oh believe me, I am...lol!

 

Nice numbers Alain! What cc fuel injectors are you going to run? I would get 1600cc injectors and call it a day. With those and a double pumper you should be good for years to come (unless you upgrade to a larger turbo and go for more power, which would of course mean it would be time to have your engine fully built).

 

nice numbers, time for more pump and bigger injectors!

 

Nice E-85 looking good.

 

dam 485-382 @21psi. christ man!!!

i cant wait to get my e85 tune in

 

Alan,

Very nice. I have tuned a few ETS 35HTA and didnt seem to hit 90% IDC (on E85) until about 25-26psi on the last one. IT made about the same amount of power so I am wondering if either his gauge is off or if your pump might be old? I noticed in my car when I dropped a fresh pump in (it was 2 years old) I saw a decrease in IDCs. A double pumper will cure it for sure though.

 

Nice work Alan

Great insight JB

 

Nice I have all the same mods but wanting to get bigger injectors so I can run E85. I am making very similar power too. I can't wait till I get mine tuned now on E-85 thanks Man

 

crazy power man! congrats!

 

Very nice Can't wait to get on the corn fuel

 

Good job man. I love me some e85.

 

this is what i want a 35r turbo and tuned on E85!

 

Good job I have the same fuel set up for my stocker snail.
