whats up guys im a firm beliver on no2, and i was wondering with a full bolt-on car with a t-rex, where should i spray it rpm wise?im going to run a dual stage nos 5177 with 2 msd window switches, was wondering or taking suggestions on what rpm levels would maximaize the nitrous.byt the car will be kissing the 7000 mark.thanks.

That will certainly be a stout combo. What do you have for fuel? I would say with two window switches I would activate the first stage at 3500 and the second stage at 5500 and shut them both off at 6900-7000 rpm. It will be a monster! Be sure to reduce timing and if you start getting above 570-670 rwhp I would go ahead and use some 100 unleaded or greater.

yea, i want to keep it on pump gas if possible, i believe you know jeremy pretty well, i was discussing it with him for a while, thats when he talked me into a dual stage dry, lol.any ways i want to run the t-rex and i believe jeremy can and has tuned that cam pretty well before, and with kooks and a 90mm lsx i want to put down around 450 cam only and was contemplating what to run the dual stage at, probally 100+100???sound good?

650 total is going to be cutting it close on pump gas. Of course with the cam it may make it easier. Jeremy was able to get 610 rwhp on pump gas with three small stages. Tq was around 525 rwhp though...and Tq is a better indicator of cylinder pressure and the resulting timing needed. By him doing three small dry stages he was able to keep the Tq spikes down while carrying the Tq farther out in the rpm band to make that 600+ rwhp. All on pump gas of course.

Give it a shot but be sure to watch things closely.

Right you could be ok on pump stuff but a careful eye on the tune is a must. With 25 degrees of overlap on that cam you should bleed enough cylinder pressure to make it possible with enough timing pulled.

awesome, the project has started, and we'll see how it does, im probally going with a 100+100, i might bump it down a bit, i havent determined that yet, we'll see how well the stcok bottom end holds up, jeremy's vette handeld a 240 shot (3 stages) so we will see.thanks for the help
