- The high torque numbers are you are seeing from stock turbo/e-85 cars is from the ginormous boost spike. IE, 28 PSI on those like tiny turbo's.
E85 is probably the BEST thing to EVER happen to the stock turbo'd SRT-4's I'm really surprised that Nick's stock turbo record has not been beaten yet.
I wrote the first E85 stock turbo tune using my 1025cc injectors on my on car way back on September 2010
. I quickly realized that E85 can fill the large performance gap between stock turbo and entry level big turbos. Ever since I've been heavily promoting stock turbo E85 use. Now I am arguably the #1 proliferator of stock turbo E85 tunes with over 200 injector/tune packages sold so far. So most dynos you'll see are using my E85 base tune.
When tunerlover3 was on one of my first E85 base tunes, he made just 9hp less than his current best. As Dan said already the A/F weren't great but shows that there not much more the stock turbo can do.
Most dynos I've seen from my customers range around 290whp all the way up to 341whp
. But if you ever ask me what my tunes will do I'd say around "300-325whp--DEPENDING ON THE DYNO"
Now with that said, I will never
condone 27-28psi spikes from a stock turbo. Its just too hard on the turbo and the high air temps are counter productive. 20-23psi, which is where my tunes are setup for, is more than enough to deliver great performance without needlessly beating on the turbo.
