Go really fast I cant get past 140 I need two bottles the big ones.

Actually I am wondering how my ECU will know I am spraying. I want it to trim the timing slightly during a spray. Just not sure how to do that. Time to poke around the program and read the manual again.



I am only going to soray a 50 shot. Ari at RX-7.com told me I should see 100 more to the wheels if I tune it right.



I have decided to get off my ass and tweek out this car and go ape **** with it. I think with some more dyno time we can get close to 400 rwhp without NAWZ and with we should see close to 500.

I cannot find my wiring instructions for the NOS. I searched briefly last night but could not find. I'll look again today.

I am running a Motec M-4. No issues there. When I had my stock engine and ECU with a FCD it did not work too good.



I did not have a boost controler and the turbo would boost to 15PSI while spraying. I would end up hittong fuel cut anyway and runniong the rear rotor on N2O and fuel from the wetshot only. It weakened the rear rotor but it didn't blow.





I am imagining the turbo will spool up real fast when spraying. MY Motec is programed to read manifold pressure so it will compensate fine. Plus I am jetting the NOS to spray really rich. I am even installing a dedicated fuel pump for it.
