Correct me if I'm wrong, but a 50 hp shot for a v-8 will not put out 50 extra horse on a 4 banger. There are half as many cylinders, you'd have to jet up the 4 banger to get the extra power, right?

On the kits that claim they are rated safe for fuel injected engines, I know you should upgrade pistons and other components but is it a must??

Some kits claim they can safely add 50-75 hp without any major modifications. Is there any truth to this at all??

If the kit isnt installed right and you predetonate hard, It matters little what pistons are in place. ZEX and Holley (NOS) both agree you can go up to 100-125Hp shot without modifications other than proper plugs and timing retarded

Chadow, on real "kits" engineered specifically for your application, the orifice holes are different sized. A 4 banger kit will have different orifices than a V8 Kit. The generic cheapy "fit all" kits are the ones that increase the danger of predetonation.

Many of you are actually interested in Nitrous and both NOS and ZEX have excellent websites with a vast database of knowledge. Stop relying on heresay and "BillyJoeBob put one on and blew holes through his pistons and the manifold went through the roof". I have used nitrous since '76 . The GXP is the 3rd one and after 8 bottles of NOX in my GXP with a 75 Hp shot I've had no problems 'cept for toasty spark plugs that I wasnt suppose to use in the first place

No engine mods are "safe". They require carefull forethought and research and follow through. I myself dont believe putting a smaller pulley on a used */C and running it near or cough Will cough above the threshold of a new one is safe either But you have to make a decision balancing how fast you want to go vs how fast your engine wears.

Dirthead,

what kind of scanner are you using while running your NOS? Also, you say that NX lists the jet sizes - where?

i guess i need to do some research into this wet and dry thing too.

one last question -why and how would you "hide" a NOS system? It looks pretty obvious on your setup.

The tech data talks all about the wide open throttle initiation of the NOS. so, in a drag/street application if i have the system armed it is going to use NOS as soon as i floor it. is that how you run your systems? does one need to worry about the tranny (big worries with our transmissions ) during shifting?

Exellent post DH, And again glad to see an */C member get some positive info out. XX I have the TPS system you are thinking about and it takes alot of fiddling and testing to get it where you want unless you add a go button like DH'* and just activate @ 2000-2500rpm. (Those kits are more affordable.and with your tranny issues it probably the best bet) I have a larger tranny and love the chirp into 3rd gear and the pull of the Torque Manangement.( Now that I'm use to it.)

Your in new territory and your trannys response is questionable and I respect DH'* unwiilingness to say it'* ok. Dragracing is a gambit. I guess it'* an equation between what kind of times to you want to post vs what wear is happening to your drive train. If its your daily driver and you cant afford parts as you wear them then I wouldnt go this route. But smaller pulley'* and other mods are doing the same thing.
The point here is that if you want to be aggressive at the track and can fix things as they break. Nitrous is an execellent way to step up and play at new level. For all the "accepted Modding" here in the Club, I can see where its great to race each other and compare times,... but some (Hand raised) want to be able to be competitive with the other guys.

No kill stories here but you cant imagine how gratifying it has been to knock down some of todays best offerings with a mere 75 shot. Given the GXP and The SSEi are inside a second of each other I expected NOX would make a big impact on the latter given it can be retuned where my N* cant.

DH, I hear ya on the plugs, even the 75 shot cindered my Plats pretty good and I have some AC441LT plugs that are one range colder plus recessed tipped fine wire plugs ready to go in (lost License so in no hurry) They are highly recommended by a SSEi member here that drags often (no nitrous though), made for */C and hear they are also good for NOX applications. I would be happy to send you 6 (Gratis) just for the info and feedback on them. The money I spent on them is nothing compared to a N* crate engine and would be glad to donate to the cause. I tried the 125 orifices and got quite a knock with OEM plugs and I think the plugs are the key. PM me please if your willing to try them. BTW The Zex site has a good chart of orifice sizing.
