VQ37 (370Z) Before and After dynos
VQ37 (370Z) Before and After dynos
Got this over from the370Z from FI new TDX exhaust..
Here is where we are at so far:
Baseline (Stock)
Run 1- 281.94 RWH / 241.25 RWT
Run 2- 276.51 RWH / 241.52 RWT
Run 3- 284.12 RWH / 240.89 RWT
Baseline Average: 280.86 RWH / 241.22 RWT
F.I. TDX Cat Back 12" Resonators / Stock Cats
Run 1- 300.81 RWH / 251.08 RWT
Run 2- 301.62 RWH / 252.11 RWT
Run 3- 301.30 RWH / 253.89 RWT
F.I. TDX C.B. 12" Res. Average: 301.24 RWH / 252.36 RWT
F.I. TDX Cat Back 12" Resonators / F.I. Resonated Test Pipes
Run 1- 308.99 RWH / 259.05 RWT
Run 2- 310.24 RWH / 258.32 RWT
Run 3- 305.37 RWH / 258.70 RWT
F.I. TDX Cat Back 12" Res. / F.I. R.T.P. Average: 308.20 RWH / 258.69 RWT
F.I TDX Cat Back 12" Resonators / F.I. HFC's
Run 1- 304.35 RWH / 258.33 RWT
Run 2- 304.19 RWH / 258.25 RWT
Run 3- 305.79 RWH / 258.50 RWT
F.I. TDX Cat Back 12" Res. / F.I. HFC's Average: 304.78 RWH / 258.36 RWT
During the dyno runs of the HFC's & R.T.P's I started the think as to why it wasn't making more power. Then I reviewed the numbers and realized that they were pretty standard as far as gains go. Remember that this car has stock air boxes and stock air filters. The car is only taking in so much air so it can only let out so much exhaust. Now, I am confident that the HFC's and R.T.P.'s will play much more of a part when a good cold air intake setup is on the car.

Do you have the graphs? Does it show gain across the entire RPM range?
The numbers don't mean much if there's drop off but produce +20 only at redline.
