I have a Sti with a cold air intake, walbro 255 fuel pump, 1000cc injectors, turbo back exhaust on e85 I will be making around 400 whp I hear stis can only handle 400whp! Is my car in danger of blowing something with this kind of power ?

 

If you have a good tune and don't abuse the car like crazy, it should be fine. It is never a certain thing with modded cars on whether how the motors handle the additional power. Some people blow their motors with no mods at all while others make 350WHP+ with no issues.

 

You won't be making anywhere near 400 whp with a stock turbo on E85. Most E85 stage 2 STIs are making between 330-350 whp. You can break 400 whp on E85 with a TD06H-20G if you have a high ready dyno.

 

I was surprised with my results as well but I have 850 cc injectors right now in it so in the spring time ill be putting 1000cc in and on 850 I made 371 whp with e85 JR tuned my car at P&L Motorsports

 

I know Junior uses Airboy when road tuning and his numbers are always retarded (unrealistically) high. I didn't know their dyno was as well. I assure you unfortunately though that on any other dyno you would make far lower numbers. 850s are more than enough for E85 on the stock turbo. 1,000s would be a waste of money on your part.

 

my sti on e85 and gt30 makes 440whp on built motor, my sti's motor blew with 290whp..they are ticking time bombs

 

Well the only reason I am switching to 1000cc is bc my car bogs like crazy at 3000 rpms they said it would be the injectors but I don't have an idea on what it is if anyone can help that would be great!
