Stock Intercooler (Next Upgrade)

Stock Injectors with FPR



Please your advise is greatly appricated i want to achieve 450 Hp to the wheels on the stock motor is that possible and if yes please advise How?



Thanks and best regards

 

you're looking around 380hp @17psi, its hard to get the boost any higher, and the turbos are way out of their effiecncy range

 

not sure stock injectors can handle all that can they?

 

not likely! if you need injectors let me know I have an extra set of 850's for sale that should give you plenty of fuel for what your looking for.

 

If your gonna go over 14psi of boost you should upgrade.

 

Twins won't last long at the boost pressure.

 

the guy that siad 380, it could be done, but **** it wount'nt last long

the 99 bats came with 206kw or 280hp, but every one knows thats more likey 320hp. i'll just run it on 12psi till you can upgrade the fuel, then turn it up to 15-16psi, that sould get you up to 350-370hp. but yea you will have to start thinking of going bnr or single to get to 450hp reliabley.
