Hey, think about this. NA I am trapping 99-101 MPH. With the 75 shot, I trapped 110.7. We're looking at a good 100rwhp gain from the N2O. Judging by my NA MPH, I'm assuming I am at roughly 320 RWHP. 320RWHP + N2O (100 RWHP) gain, is somewhere above 400 RWHP, app. 420 RWHP.

I am running a single pattern camshaft (check sig) which really is a slight reverse split @ 220/219 .633''/.631''.

Also note, I'm using Thorley 'tri-****' headers and full 2.5'' exhaust.

Soooo, what are we looking at exactly... A single pattern camshaft can support upwards of 400rwhp thru full exhaust. What will adding exhaust lobe do? Boost top end HP, aka more MPH. Taking exhaust lobe away will do what? Make more torque? Heck, I'm not even loosing MPH yet on a SINGLE PATTERN cam ya know.

Just thinking is all....

Excuse my ignorance, but Im fairly new to the idea of NOS, but how long does the 75 shot usually last for? Do you spray through your shifts or do you have a controller that skips over the shifts? When did you start spraying on your run Sport Side?

I start spraying at 2000 RPM in first gear and stop at around 5500 RPM in third (the entire 1/4).

Does the 75 shot usually last one run or multiple?
