What octane are you running for the graphs above?

Ya I bet you will get close to 420whp with more boost and E85

400whp seems doable! nice setup

yeah over in socal we have a few guys over 400whp on e85, good luck

^ over 400 with what mods

Those are all nice mods that will support the 400+whp goal, but the stock 05 turbo is strehing

you should get there, good tune will do it!

um, im not knocking your set up, but 378 whp on 21 psi of boost on stock VIII turbo? it took me e85 and 28 psi to get 376. what dyno was this done on?

Thats DLL horsepower...thats probably not calibrated correctly for his car imo.

i say about 25hp on e85

But is E85 available in your area?

This is a stock VIII turbo without a porting?
