Apparently not! 2004 STi in the latest Turbo & High tech Performance produces 720awhp @ 32psi and ran a 10.2 @ 140mph and is a daily driver complete with full stereo system, power steering, air conditioning, STOCK cams, STOCK USDM STi transmission, and with only the aid of UTEC! Here's how:

Car was driven an hour each way to the strip when the 10.2 @ 140mph was run. Even though this STi is in Puerto Rico, it is (was) US-spec.

 

so is that the fastest or most HP a suby has ever put out ?

 

Old news, have you seen the videos. I can find the link.

By the way Puerto Rico is the USA, of course is going to be US spec STi.

There you go. I think I posted this here before. The dyno sheet is on page 1, the videos are in there too.

I believe the 10.2 was their first run after the dyno, with more tuning time and adjustments it coul be faster

 

take off the hoosier's and that time will rise to probably almost 11's. bad ass though, makes me think about getting the STI 6 speed

 

crawford does some great things...

 

how is a race built shortblock, and all those bolt ons getting 720 AWHP yet it's only with the 'aid of a UTEC."

 

Low 10's isn't surprising? Sure, there are many cars that are much faster, but are they daily drivers with a full interior, working air conditioning, power steering, and full stereo? Stock tranny nonetheless.

 

What i'd give for a street driven 720 whp



Damn 32 lbs, if you're motor blows its likely to kill any spectators within range of the debris.
