yeah I know I read the nitrous section and do the research, but i went to the track tonight and i made a mistake, first of i got a zex nitrous with NMU and it activate on a WOT i only spray 50 shots and i already got a step 1 colder plugs, my usual launch rpm is about 1500 and after i let go off the clutch i accidentally hit the full throttle in less than 2800rpm, so about 1500 it kick in right away to 4000 something rpm. after that pass i smell a potent burnt clutch in my car, the car runs fine i still made a lot of passes maybe about 10 1/8 mile test and tune.

just FYI: i notice that my car runs slower when im using a n2o do to the fact that i spin so much every time that it will activate.

my question is???? does anyone of you experience nitrous activation on less than 2800rpm more precisely less than 2000rpm? note that im only spraying 50 shots and how come that the clutch is burn by that circumstance.

my car still runs great but im worried that mess something up that i didn't know about

the lower the start rpm, the higher the trq. with a 50shot making 50whp, at 2000rpm you will 131 ft-lbs extra, at 2800 it would be 93 ft-lbs

so you were prolly making close to 350ft-lbs at 2000 rpms. that will smoke most clutches and bend the stock rods.

Don't activate the nitrous at such low RPMs. Since you aren't quite able to modulate your throttle, you may want to look into a window switch to pair with your WOT switch. It's just safer than what you have because nitrous is only activated within the preset RPM range AND at full throttle.

why dont you guys run controllers? i cant get my head around it, its the first and formost thing you should do when you get NOS.

its completely adjustable.

I run mine, with a start of 3150 rpm, i shut of at 7060 rpm, i can ramp gas up low down , adjust it where i want it, pretty much a no brainer hey
