alright my camaro makes 407 rwhp, i want to add a 75-100 shot if nitrous in a dry shot.

i already have ngk tr6 plugs, but i think they are gapped at 50. is this still okay for a 75 shot? i dont wanna have to regap them, its such a pain in the *** to pull these plugs on an ls1 lol.


anyways, as far as tuning, i have a local dyno with a\f and everything, so i would do it there. now, would i have to keep 2 different tunes?

like a n\a tune and a nitrous tune? and just upload it to the car when im going to do either or?

i currently have done my tuning with ls1 edit, and have it set perfect for n\a.


so how do you go about tuning?

 

Yes, re-gap the plugs. Chances are you'll need larger injectors, so you will have to tune for those. If you advanced your timing more then a degree or two for the cam pull that timing out, if it's only a degree or two the dry shot will usually pull that out automatically. Nothing else to really tune for as long as the NA tune is good.

what is the stock injector size? and would i even need to upgrade with a low 75 hp shot? what size would i go to?

 

Since you have a cam yes, you'll have to, or you'll run the duty cycle over 100%. I would suggest a set of 32 or 42 lbers.

its not a hardcore cam, only a .224 thunder racing... i wonder if this nitrous thing is even worth it, i might just stick with my rearend, should get me low 12's. for the extra grand + and possibly screwing **** up, might not be worth it.

 

extra grand ? A simple dry kit isnt that expensive either is a set of injectors . You will not find a better hp for the buck Once you spray once you will be hooked and so will your car LOL.

 

Matt at HSW has great prices on his kits and his injectors.Iwhent with 42lb so i would have room to grow

 

do i have to upgrade my fuel pump?

where can i buy injectors? and what do you recommend i go? 42 lbs?

 

yes go with the 42lb injectors

 

I wouldn't be a bad idea to do an upgraded fuel pump, if you go wet or dry. If you go wet you won't need fuel injectors. We carry a few sizes:
