Had a fun weekend in Watertown SD. Had the car tuned by Andy, the short of it is 545rwhp/486rwtq on an 8lb kit. More details are here:

and a video
posted later

This is the first E85 (Corn) Blown F-body that we know of. Its also a flex fuel vehicle as well. The tuning was doen using a Prototype Predator Programmer. Not bad for just bolting things on a car. I also wanted to note that this is with a stock fuel pump and a Kenne Bell Boost-A-Pump.

This has completely exceeded my expectation.

Big thanks go out to rubbersidedown(Andy), morejuice(Jesse), and JUSTIFIEDC5(Ryan). Thanks fellas!

thanks.

The top chart is the E85 tune and the bottom one is the 91 octane chart. Just wanted to show the difference between the two.

What kind of fuel pressure are you getting with the boost pump? How well did it hold pressure at peak RPM ?

TIA

E85 has a lot of promise for the future. Can you PM me the A/F ratios on E85.

DAMN :eek2: E85 is working great with forced induction LS1
nice numbers again now take to the track. :)

Hey I used to live in that part of s.dak. Do you have a web address for the tuner in Watertown. My last name is schlekeway. Thanks.

I don't know what the AFR was on the E85, I was running the camera during those runs. I was told to not disclose that information anyways. You would have to ask the tunner.

As you can see the fuel pressure was fine on the 91 octane gas by the looks of the AFR. I'll have to ask how the pressure was throughout all the runs.

I just talked to him, the pressure stayed the same (60psi) for the 490 run. It dropped slightly on the top end on the 545 run. We think that the pump is not the problem though. We had a gauge on the rail, it might be the rail but certainly not the injectors

The track numbers won't happen until later this year. Its not really a track car, seeing that it still has the stock 10-bolt w/3.73's, stock clutch, and stock Goodyear F1's

I'd like to know the A/F on the E85 as well.

Nice numbers for sure :cool:

So you dont use the Boost referenced regulator, to lift the pressure ?

stock in tank pump (with stock regulator) The boost-a-pump is a voltage booster that, when triggered (by 3 or 5 psi switch) raises fuel pump voltage to anywhere from 15-19 volts, enhancing flow by a bunch (don't know specific # off of the top of my head) they've been used on mustangs for years, and we've used them on quite a few vettes...

Prolly like a Caspers volt booster, thats probably a good thing if you are using the stock stuff.

NO JUICE,
Nice numbers, that thing should fly, or the ring gear out the diff. :jest: Hope you get some TIRES.

when are you going to use e-85?

lol at the chopped pics of you car. E85 should spread more as ethanol production rises. I'd really like to tackle a project like this.

It was a fun weekend, very impressive numbers. Congrats again Justin. Like Bonestock said, your gonna need some tires...

I knew there was a good reason my car has John Deere colors. Putting down some very nice numbers I like the combo. Gonna have track times any time soon?

congrats on the #s, this is exactly the type of thing Ive been hoping would happen. if I had the knowhow to tune, Id def/ be trying to figure this stuff out. very curious about how you got it to be flexfuel. so you can have half tank of 91, and half tank of E85 and it will run good still? or do you mean you have two diff. programs you can load into the pcm with the tuner to run on either? we still dont have very many E85 stations here in michigan, so it'd be kindof hard to have it E85 only. how have you gotten around the "30% more fuel" issue? holding the inj.s open longer by somewhere close to 30%, or is the fuel press. jacked up with the volt blaster when on E85, or what?
its too bad your tuner doesnt want to share what he's learned so far with the class. cause thats whats gotta happen for people to start experimenting themselves and make this stuff more widely used. and as soon as its more widely available, and used, it'll be cheaper and they'll put in more pumps across america. its a big pyrimad affect that needs to start with people sharing information.

no doubt tell your tuner to spill the beans!
