Just drive the car, and a few ponies won't be noticed except by you. What counts is how it performs on the track!(and the street)!
Gear head with 4.56's

Re: Do gears affect Dyno Numbers?

Just wanted to post my experience.

Here is a dyno of my car. The green line is with 4.10 gears, the red line is 4.56 gears plus I added long tube headers and an off road x vs the off road prochamber and stock manifolds I ran during the green line. Both runs were dyno'd on the same dyno, both SAE corrected, and both received dyno tunes by the same tuner (air fuel and timing were nearly identical).

Assuming the long tube headers gained me 12hp (which is common), I lost 4% due to the gear change. So my numbers should be more like 326hp/322tq.
