Re: horsepower per psi

I would say 5-10 HP???? It all depends on different variables.
When I get my dyno sheets mailed to me I will tell you what my engine gained or lost.

Re: horsepower per psi

it all depends on what part of the turbos efficiency range you are talking. Most common answer is 10 hp per 1lb of boost, but when you hit the sweet spot it can be 25-30hp per pound of boost.

I know on my motor going from 20-24psi picked up 125hp.

so there is really no definitive answer.
