Im looking at the P-1SC with the 2 core intercooler . Is this sufficient
enough for 6-8 lbs ? If not any suggestions ? Thanks

 

I prefer the twin hi-flows over the 2 row intercooler. The mounting location of the 2 row I/C (hangs below and a bit in front of the radiator) can cause over heating problems with your car. I believe it disrupts airflow around the radiator. For 8 lbs of boost, either one will work fine to lower the IATs.
