Just thought i would let you know how me and a couple of my mate got on, on the rollers yesterday:
My mates Skyline R33 GTR V-SPEC standard should be 280 bhp and all he has done is Exhaust System and Racing Suction Kit and it pushed 328.7 bhp
My mate in his nova made 169.4 bhp out of his 2.0 16v Redtop.
I made 219.8 with 275.2 nm (205 lbs) of torque, and thats from changing the exhaust system, veccy c inlet, air box mods, dump valve and courtaney sport samco hose kit.
so yes yesterday was a good day for me
I will be trying to sort out a big rolling road day for everyone on the forum as the power station i one i for most correct set of rollers in the uk.
