Hi all,

I have a caged TT4 car thats 2600lbs with me in it making 231 whp (dynojet) tuned on 93 octane. Its a stock engine, tuned with flashpro with a custom intake, headers, test pipe and no muffler. I am looking for a little more torque/hp and wanted to know if anyone has converted to e85 from a 93 tune on N/A and how much of a gain they saw. I know it is minimal, but if I could expect an additional 10hp/10Ft lbs, it would be worth it in my opinion. Has anyone done it for N/A? I am well aware e85 has a higher advantage for high compression or FI cars. I am wondering for a stock motor.

Cheers!
Eric

 

@anorexicpoodle has done this. Let's see if he responds to the tag - he did in the other thread necro for kirky seats.

 

Yep I have this setup. My car made 232 on California pump swill 91 and 242 on E85.

The real strength of e85 is how it pulls heat out of the head and intake tract. The car will be faster on track than the dyno indicates.

 

That's pretty good whp with 91 octane, Did you see a similar increase in torque? Yeah that heat benefits are another plus. I am also considering the Urge Jerk Bumpstix. Seems both options (Cams vs e85) will net me 10whp each and both are about $1800. It would be janky with my flashpro.
