You really can't compare dyno numbers there's always different variables. As long as your car is running strong don't worry about the peak number. If you keep adding parts and tuning and that number keeps going up than your doing something right, just make sure your using the same dyno everytime.

Was the 60rs brand new? If not maybe the resonator is bad and causing a restriction?

tsoshi2007

yes i bought it brand new from AJR

fenixv8

try the stock header

just curious why you did go with T1R and not a J's? i went with T1R is b/c of budget.

To me it seems the parts don't match very well. T1R header has a 65mm collector if I'm not mistaken. And to go from 65 down to a 60mm TP and exhaust would seem that it would restrict the flow more or bottleneck it. Im no expert but maybe having a 70mm TP and exhaust would work better with the larger collector than having it bottle neck at the TP. Maybe thats why when the exhaust was taken off it showed a higher gains? Im just tryin to throw ideas out there.

i was on my budget too and thought the new T1R becomes one of the best header out there

tsoshi2007

it could be. but considering it is my daily drive so i dont really wanna go 70 exhaust.

wow good point and yes it is a 65 mm collector. there are some quiet 70 mm single. or you could go dual. my set up is not the best but have proven to give me gains.

Well...we would need to calculate the Reynolds number for the exhaust gasses as they pass through and expansion chamber that then compresses for a long duration. I have the feeling it will not be a favorable number for long duration laminar flow.
