03 I35 4AT Dyno
I had a chance of putting my 03 I35 4AT on the dyno today. I am kind of curious to know why the difference between the max horsepower and the max torque since most dyno graphs i see here are almost the same. Also, can anybody confirm if these numbers seem right for my car and mods, i tried looking around but theres barely any auto dynos with no tune in here. Any opinion is appreciated. Thank you
max power was 209.52
max torque was 230.15
Mods are as follow:
Gutted precats and main cat
Custom Cold air intake with a aem filter on the drivers wheel well
CXJ 3 pcs Phenolic Intake Spacers
CXJ BOP
2 degree timing advance
Knock sensor resistor 560k ohms bypass

A dyno measures just torque. Horsepower is calculated from those numbers as: Torque X Horsepower / 5252. The two curves always cross at 5252 RPM on the dyno sheet.

Breathing mods tend to give more HP, at higher RPM's. I was similar to you when I first started, I was at about 210 and 225 or so.
Most recently I was at 257/245 or something like that, and as I tracked my progress, my hp slowly began out pacing my torque. 210/225, 233/230, 242/238, 247/242, 257/245.

This probably needs an update and a cleanout but in any case, should help answer a few questions for you.
