Hi,
I have an r33 gts-t with a hks gt2835 pro s and all supporting hardward, run by an apexi power fc
at the moment im making
320rwhp @ 12psi
and
337.7rwhp @ 16psi
now i am happy with my tune but not happy with the overall hp figure, ive done a search and found other people are making much more power with the same power and same mods.
my question will be is, im running a custom fmic and piping
now i know for a fact my piping has been cut and rewelded to fix my car, and the overall design of the piping looks average, also im using a china cooler. could this be casuing a flow issue and therefore giving me a lower power?
also i have a feeling that one section of the piping, may not be complete smooth on the inside possible causing turbulent flow
