As the title states. What's the highest whp that had been achieved using pump gas 91 only? (no meth, no alky and no race gas of any sort)

Chime in too on what setup would that be to achieved that horsepower and on what dyno.

And oh, I've used the SEARCH button but only came up with the 93/94 octane thread, not 91 that I've been looking for.

 

the highest power I got was 429hp, according to Evoscan. Setup is on GT35R with high flow cat.

 

Crank or wheel? Also, what 35R ur using if u don't mind telling.

 

That's pretty good power for 91 pump.

 

My friend made 418whp/340wtq on a GT35R on 91 with the AMS kit.

 

FYI...

Highest whp 2.0L EVO on 91?

 

Was that vortech_g35?

 

I guess I didn't search hard enough, besides, I'm not looking for just 2 liters, strokers are welcome too.

Thanx anyways.

 

Well a 7.4L stroker could get you in excess of 650hp on 91 oct.....

i dont have dyno numbers yet....my aem calculated numbers are claiming 423 @ 7500 revs...

the power curve calculation is based off of a 360 whp d.j. pull i made a while back...my road tune acceleration scaled numbers are pretty close to my 360 dj pull....peak power numbers are @ the same revs.
