didnt see this exact question in the search. with 10 psi and all the bottom end done right to handle the power. stock complete type R head intercooler and aftermarket tuning what should one expect to get to the wheels? I picked 10 psi so I could drive it daily with no worries and have it last along time. is 300 whp out of line for this set up. It would be 8.5 or 9 to 1 compression. thanks for all who reply.

 

It's really going to depend on your setup. IE turbo, and tuning... You should have no problem hitting 300 hp on 10 psi on your R....

 

remember a good rule of thumb

u pick about ~8-10 whp with every 1psi
on a good conservative tune

 

that sounds REALLY conservative? don't you think it's a bit more?

 

you will hjave no probs if done right.

 

This depends on a ton of factors. If you have a more specific setup in mind, that would help.
