sweet, do you shift manualy or use a window. i was thinkin about putting a rachet shift setup in but can only find them for the third gens. I seen a guy with a b&m rachet shift setup with reverse lockout but i dont think he put it in cause he wouldnt go into much detail on the install. Im curious about your setup i think im gona give up on the rachet shift idea and just go with a window im just not shore how they work. I mean i know its to avoid spraying through shifts but is it ajustable or what?

i let the computer do the shifting of the transmission. i have a FJO dual stage window switch. only use one side of it for now. the 75 shot will be on as soon as i nail the throttle. then, i'll have the 150 come on about 3000 rpms.

His car is a 98 and i think its different than mine. Mine has a switch to the side of the gear selector that tells the computer what gear its in. Im completely lost on this and dont know if you can remove it or bypass it or what.

Dual stage meaning you have 2 sets of fuel and n2o injectors right. Like a button for the 150 and another to boost the extra 50 out of the other set? Ive been looking into nitrous a lot, funny i never really came across how exactly its set up though. I was thinking of doing the same...150 shot with an extra 50 when needed, or vise versa if its possible. Also thought it was weird that you got your lowest tq rating with the highest shot. Whats the reason behind that?

pics of the system is on my website. click the 00 formula in my sig. they are two complete nitrous systems. i put a T off the fuel rail. some will also T the nitrous line. i put two microswitches on as well. i can run one or both. the stupid thing about the dyno is it started recording at 4200 rpms. i started the run at 3300 rpms with te 50 shot. the 150 came on at 4000 rpms. if i switched over to time or mph, instead of rpms, then you could see the first stage come on. so, you are only looking at the second stage coming on.

your point?
