Car Info: Blue STi +Red del Sol VTEC
The thing that i laugh about most is when everyone says the turbo will only make 370 t0 400 at the crank and the injectors.
Think about this i dynoed my car at xxtuning and it hit 261hp and 270lbft. With a 25% drivetrain loss your looking at 350hp. Shiv's dyno shows 218 at the wheels and he even says his dyno is low since it's a load type dyno has lower #'s. Their baseline for the evo is 185hp.
Explain to me how a 3200lb car with 220whp runs a 13.0 or high 12 stock. Don't say the awd launch yes that helps quite a bit but where's the 105mph trap come from.How does another 3200lb car do mid to low 13's with 185whp and trap over 100. Easy it doesn't happen the sti's has about 350hp stock and the evo's like 310-320.
When i get my vishnu stage 1 i'm going to dyno it and i'm expecting about 310whp 325wtrq on the 93 map and 330whp 360wtrq so i don't know how 370 at the crank is the limit will make sense.
Also the stage 1 STi will run high 11.75-12.2@115-120mph and the evo will do 12.1-12.4@110-115mph. All this with 280whp and 250whp respectively. It just don't make sense when a viper has 500hp weighs the same and traps 120-125mph. The STi and Evo must have the most flexible motors on earth for that to happen.

and the stage 1 sti will run 11.75-12.2? wow, id like to see that. im not saying its not possible, but the figures seem to be a little farfetched

stock sti hp
masto subaru in tampa has its own dyno. the service manager drives sti and just added turbo back ehaust. he says they dynoed it stock at 266 hp to wheels before changing exhaust and 286hp to wheels after replacing stock ehaust.this sounds more reasonable too me! silverfox1

Folks should not forget to account for fuel used and physical location.
Folks in in CA are at sea level and only have 91 octane available at the pump. Meanwhile you have folks in Colorado Springs running 93 octane like most of the country but they are 6K ft above sea level. Then there's me in NoVA running Sunoco 94 Ultra and has access to Sunoco 'GT 100' 100 octane street legal go-go juice.
Dyno the exact same car on the exact same type of machine and you'll get three different values. Bottom line there are lots of variables not to mention breakin. My STi is factory stock and strong as hell. I think thats partially due to following the break in to the letter and also that I've been running it on 94 for ages. Of course your own mileage may vary. The STi _definitely_ produces more power on 93 octane than 91 and is quicker to rev with 94. I'll let you know about 100 octane later this weekend after I fill-up on a tank to see how it 'feels'.
The bottom line is that its well known the STi makes at least 300/300 on 91 octane and at sea level as per all the dyno reports coming from the west coast including Shiv. Depending on your location, fuel and motor conditioning as stock your results can be better, though within reason. As stock we are not making 350HP at the crank. Otherwise we'd be giving Z06's a harder time than we are on the streets or the drivetrain would be much less efficient than it actually is.
The STi is though by all accounts and measures a beast bone stock.
A fact which cannot be doubted.
