What fuel pump do you have?

 

forgot to add that walbro 255

 

Rewired?

 

I would guess 420 whp/400 Tq on E85 if your 255 can handle it.

 

91 tune should look better than last time. My guess is 350 whp/ 330 Tq.

 

results are in!

382awhp 336 tq @24psi on pump
416awhp 354tq @20psi E85

still had some room to go with E buttt we believe either i have an open front diff or my clutch is starting to go. any higher it would not hold power but very intermidnate. super hapy with it though. way smoother, pulls hard, and of course the wonderful smell of E. big thanks to Aaron at English racing, only person i trust tuning my cars.

Nice!!
Your E85 boost can't be 20 psi.
Looks like it hit 26 psi and dropped back.

 

You're at 12.2 AFR on E85? Looks like you're out of fuel.

 

it's crazy the numbers you guys get sometimes lol. i mean it's hard to reference anything without actually seeing some track data.

 

It's amazing how much a stock 9 turbo can make.

 

geez i'm still on stock 8 turbo but am about to switch to the 9 too. no e85 though lol

 

ix turbo is deffinatly worth the extra little power you gain

 

Your E85 is at 20 psi, while your gas tune boost spikes to about 26 psi and drops. Why didn't your E85 boost to 24-26 psi?

 

It looks like your tuner ran leaner in the mid range to get your power close to your gas tune. Gas tune has an extra 6psi spike advantage. Are you planning to track car on E85 and run gasoline on street?
