Nitrous woes

zerofx150 · April 24th, 2008, 02:58 PM

ok well i just went and did a test run with the 100 jets and its nuts, however i have a stumble at engagment and then it straightens out. i called NX to see what can be done to remedy that problem and they have an accumalator for 216 bucks. i dont want to take this route but will if need be. Will to pumps remedy this and how would one go about setting up a twin pump system.

I would datalog the nitrous run and see what the stumble realy is first. Your fuel system is good enough to hold what you have and the 100 shot easily. I would almost bet the stumble is the delay in the N20 hit and it is pig rich for a moment. Check it out on the datalog and see.

cool good idea now to get my xcal to work with vista

, i might try upping my engagement rpm to 3500 too.

do you have good bottle pressure ? you need a minimum of 900 for things to work properly

zerofx150 · April 25th, 2008, 10:31 AM

pressure is good, full bottle, a ran it last night and it didn't seem to do it as much.

do you have a purge on the system?

zerofx150 · April 25th, 2008, 12:49 PM

heater, purge, window switch, you name it

you might need a boost a pump, if you have a fpss then for just a split second its probrably seeing a drop in fuel pressure and shutting the nitrous off. Mine did that on occasion but not too often, i just adjusted the fpss to compensate for the quick drop since mine was set to cut off around 25psi.
