I don't mean to rain on your parade but the RSX guys have done this and they only got about 300whp + or - 10.Just checking in, I have had the kit for a year now and the only problem I have had is I melted the hi flow cat on my Vibrant RH. I am soon to be tuned this fall so I will see what she can do.
My future plans that should put me around 330:
JRSC Aftercooler built by the guys over on CRSX
IPS SC cams
Hytech SC spec header
