DA on that run was +1050'. The window switch was @ 6200 and shut off the N2O about 50' before the traps. So it probably has a bit more in it. Also remember the nitrous pressure is dropping through the whole run, starts at 1000psi and is 900psi after the pass. A N20 car will not MPH as well as a boosted car because of this drop.

This is not uncommon with CMS Stage II cams.

PapaSmurf · November 25th, 2009, 07:53 PM

so cms stage 2 cams are known to produce more hp on a nitrous shot than the actual nitrous jet rating?

GTRACER88 · November 25th, 2009, 10:07 PM

Yes. Due to the larger exhaust duration. It takes out the exhaust mass better and nitrous creates A LOT or exhaust mass. I knew it was better but damn didn't know it was that good.

I give my tuner a little credit for the good numbers as well. We spent several hours over the last year on the dyno

It's mainly in the tune. It's why your car is together. Propper fuel and a great tune makes numbers and reliabillity. It's what I keep telling people... Superflo dyno huh? Doesn't that read like 10% lower than a dynojet?

nice work, 2V DOIN IT!!

Dynojets usually read the highest which is why they are so popular. The Superflow actually loads the car like real conditions. My numbers are uncorrected so they are more than likely a little high.

JayC, how is your powerband for the street?
I know it works great for the strip, but is it soft on the street until you let the rpms rip?

mustanginky · November 27th, 2009, 12:31 PM

oh, no, JayC, not the dyno number debate on this forum as well...

Boostang · November 27th, 2009, 04:00 PM

I noticed no loss at all. These are not high rpm cams.
