Hi I am planning to make between 600-650 HP. What I wanted to know is will my intercooler piping work well?

I have 2" Piping from the turbo to the intercooler and 2 1/4" piping from the intercooler to the motor.

The outlet on the turbo is 2 1/2". The Inlet and outlet on the Intercooler is 2 1/2".

 

I'm making the same power. 2.75" from turbo to intercooler, and 3.00" from intercooler to throttle body. lol You'll probably need to run a little bit bigger piping.

 

I think you already know the answer. 2" piping is comically small. Small changes in piping diameter correspond to huge changes in volume. For example, 2.5" piping holds 60% more air than 2" piping.

I'd do 2.5'' all the way, with a 64mm throttle body to match.

 

The larger the piping, the less pressure drop. You are probably going to be on the very right side of your compressor map for that horsepower (totally depending on your turbo) using 2in piping. Why would you decrease the piping size right off the turbo? Atleast go 2.5 all the way. My actual vote is for 3in though.

 

clearly 2.5" is the choice for the hot side...much cheaper and way better flow. If you can, have someone weld on a 2.75 or 3" fitting onto the other end of your intercooler and run that, if not I don't think it will hurt you too much.

 

Where is a good mlace to get 2.5" piping for a good price?

 

I got some from T1 quite a while ago. Good prices and it welded very nicely with just a wipe clean.

 

Hopefully my 2.5" piping will get me to 700whp!!
