Well for some odd reason.. I'm making power to 8800k.. using CTR cams, with ITR cam gears.. My setup as of now consist of my crower built head, Bottem end is a Stock B18c5(JDM ITR) Skunk2 intake manifold w/ hondata gasket, NGK plugs/wires, Hypertech grounding kit, DC sports headers 4-1, running with a b18c tranny and a excedy stage 2 clutch and hondata.. Right now the car is running sickly, ran a older c5 vette i'm gussing around 95 area, the one's with the lt1's had exhust and intake and a chip and i put about a car on him... so the car is running fine, i shifted around 9k every time and never felt a lose of power.. hopefully after i get my exhust done with a new set of headers i'll be running it.. Thx for the feedback guys!!
