E85 and 91 octane tunes

For reference an average 100% stock Evo 9 puts down approx 22Xwhp / 23Xwtq on our dyno

358 whp / 299 wtq on 91 oct @ 24psi

429 whp / 367 wtq on E85

+71 whp / +68 wtq on E85

The owner wanted the boost to gently come on to help save the 6 speed. Which of course, was a piece of cake with ECU RPM-based boost control. Boost profile on E85 looks like:

26psi @ 3700rpm
28psi @ 4700rpm
29psi @ 6000rpm
28psi @ 7300rpm

This is reflected in the torque curve.

 

Nice. Great job again.

 

even making it spool slow, it spools fast

skillz.

 

Awesome! Any chance you could post an overlay of the pump gas boost profile vs E85 boost profile?

Sick numbers, that mil.spec cat is the bee's knees.

 

for real.

 

very nice torque curve

 

Or, just wondering how much boost he was running on pump gas Didn't mean to be greedy but I just LOVE the bbk boost profile around 25psi w/ ECU-controlled boost!

 

Awesome results. You guys need to open your own e85 station soon.

 

Sure I can scan the plot tonight if I get the time.

91 oct boost was 24psi across.

 

There is a E85 station 3 hwy exits north of us.

 

Nice tuning!!! Smooth power band on filter 6!!

 

nice work, great looking curve on pump and e-85. you guys do a great job with the bbk!
