What should I set my Window Switch "on" Off" to? Hey guys,
Im new to nitrous. Just installed a Nitrous Express kit on my RX7 which has an LS1 swapped into it with a 4L60E. The engine came out of a 98 Trans Am. It is a wet kit and I am running a 125hp shot. I have a stage 5 RPM 4L60E in it with I think a 3200 stall (it may be a 2800 stall but I cant remember since its been a couple of years). Motor is modded with an LS6 intake, PRC stage 2.5 5.3L heads and a TSP 228R cam.
My question is what RPM should I set the window switch to turn on and off the nitrous? Do I want it to shut off the nitrous before it shifts or to turn it off just before the Rev limiter for safety reasons in case the tranny doesn't shift?
Also I was thinking 3000RPM to turn it on but I have no real reason for this number other than I read spraying below this increases risk of intake backfire. Come to think about it, with the stock RX7 rear end which is about as strong as a C5 Corvette rear end I should probable only hit the nitrous in 2nd gear as well???
Thank for any input!

I always set mine up to turn off 100 rpms before the shifts. Made me feel better about no breaking something. Having it off for 100rpm shouldnt affect the performance either by much. Does anyone have thoughts on this? Could that theoretically save a trans?

You've got a built tranny so you might as well use it. I spray through the shifts. Turning the nitrous off before shifts can cause a lot of inconsistencies at the track. I keep the window switch from 3000 to 100 rpm below the rev limiter.
