98vtec

I never really planned on dynoing this car but I got a chance to today and decided to test my rocket e85 while I was there and got a large surprise.





Both passes are at 15psi with no timing changes from the pump tune. 70whp increase! Needless to say I left it alone and got off the Dyno before I broke my DD lol.

Setup:
Stock h22 short block
EuroR head
Crower springs/retainers
ARP head studs
Stock cams
Home made manifold
Turbonetics T-GA billet 5454
2.5-3" DP/exhaust
Tial 38mm
Tial Q
Go-Autoworks charge piping and intercooler
Rosko Racing EuroR manifold
Grams 1000cc
walbro 255

Just thought I would share

Wow! How much does that cost per gallon?

You gained 70hp with NO timing changes? Did you make any other changes?

98vtec

I bought the drum 3 years ago for 410 with 200 in shipping...so 610.

98vtec

zero timing changes, same duty cycle on the boost solenoid. obviously I had to make fuel changes since the properties of pump vs e85 in itself are different.

There are others in this forum who would do well to study this post and the plots.

Great job Blake.

Wait till you start throwing more timing at it!

98vtec

I was pretty amazed and pleased with the results. It made 283 on 8psi, 350 on 13 and 382 on 15. The first pull on e85 I actually let off early because it sounded way to "fast" and even though I had boost cut activated, tuner instinct kicked in and I let off lol.

Once I put a built block in it, I will throw timing at it but 12psi and dumbed down timing is fun enough for the street.

I'm just curious - what tranny is this motor pushing through?

H22a. M2A4.

Try Q16 now !

I'm good for now. Apparently free information I give out isn't good enough to some people.

I will perform this test again when I have a built bottom end on the Internet's Dyno (dynojet). I don't feel comfortable running the engine at that much power on the stock engine considering I have to drive it every day. If I had an immediate back up, I would not care.

Happy to hear of the great #'s!!! Can't wait to see the actual race car in action!

Curious what kind of boost you were running at ifo?
I want to go for a ride!!!

Blake, great job, some of us, who do actual R/D know how it feels to have people still doubt, and down your claims. Its fine, keep at it dude and keep working, Great results brother!

98vtec

At the end of the day I went to the Dyno, made a couple pulls and Drained the fuel. Added different ****, uploaded the e85 map, made a couple pulls and this was the outcome. If I had more data I would share it. If I could have made before and after track runs, I would have.

But I don't have that. I, too, am very surprised with the torque pickup on the low end but nothing was changed to the Dyno, software...etc and the runs were made on the same day, same outside temps and as close to the same iat and ect as I could get. These are the results. Don't like it, make your own data and feel free to post it.

thanks for sharing sir.

Ive been contemplating whether or not I should run e85 when I get to boosting my car. There's a pump (a few actually) that has e85 and isnt to far away to get gas as long as I keep it full.

Those results just decided it for me. E85 or bust. None of this crap 91 az has will do for me.

Uncle Dave

Blake great job of sharing your results,may I ask what fuel pressure your running?

98vtec

The pump E85 may not net the same results. I have never tested any from a pump so I cannot give you any insight.

98vtec

Hey Dave,

Fuel pressure is 65psi.

m4xwellmurd3r

I agree with that. The pump stuff has a variance in its quality, but compared to 91 im sure its loads better for a boosted engine

Boyle.R

That's is amazing results for just a fuel change. How did it feel to drive? Must have been a hell of lot quicker

98vtec

I don't know, I didn't drive it with the race gas in it. I honestly wanted to get back home and have a beer lol.

I just know it pulled way harder on the Dyno. Enough, as I said, to let out early.


Camera lens is cracked....sorry. but that's on the way to the Dyno on 12-13psi. 3rd gear has to be pedalled quite a bit unless the tires are hot. Regardless to what any Dyno is saying, the car is incredibly fun to drive. And in the end, that's all I care about.

Boyle.R

Goes well

I'm assuming by drum you mean 55 gallons? if so that's a hell of a deal. shipping is a bitch though, that's why I like having a local pickup for methanol (dirt cheap for 55 gallons in GA) and VP race fuels (race bikes, run them on U4 but i want to try a more aggressive, oxygenated fuel, plus for the track Z06, not sure what we'll use.... might try high quality e85 first but we'd have to upgrade both stock pumps *C6 has a saddle tank with transfer pumps for it to clear the torqur tube and transaxle... already makes 600whp 590lbft to the wheels NA. curious what an NA motor could do with the listed fuels, not methanol lol... maybe) might try to see what local performance e85 blends are available.. wonder what a drum of Rocket costs now?

and yes, any e85 that is blended from a fuel supplier will always be higher quality and much more consistent than pump ethanol. but hey, that's why they make ethanol content analyzers for fuel systems now


I wonder how Rocket would stack up to FTWs E85 offerings
