I'm thinking bout adding a 20-30 shot of NOS in with my 6psi JRSC setup this spring.

Has anyone here done it?

I've heard of using a wet kit causing the blower to loose its teflon coating since your sending in fuel and nos b4 the throttle body into the intake, but i've talked to a few people who've done it and they say they've never had any problems after driving like that with a lot of runs even.

Also I know that adding a 20 shot, will easily add more than 20 hp since the NOS adds a cooling effect to the pressurized air so I'd have to add more fuel than normally expected since its cooler so more dense therefore needing more gas.

Any ideas of how to get a NOS + JRSC setup running efficiently?
plate kit between the manifold and blower possibly? or could I tap it into the fuel line/fuel rail?

I know a bit with the JRSC cuz I'm always reading up on it and doing my own work with it, but I'm a NOS newbie so any help would be greatly appreciated.

thanks

 

Yes, I have heard the same problems of the Single Fogger Wet kits causing problems with the blower, and they are true. For the cooling effect you'll wanna go with a dry kit of a 20-30 shot, tapped as far away from the TB as possible. That way the N2O will better mix with the intake charge and thus you will have better distribution and cooling effects. I assume you already have a decent fuel setup, so it should handle the fuel fine. Dyno tuning is the key though, you don't want to detonate. You can go with a plate kit, but the cooling effects won't be as much, and the smallest shot is a 75...you'd need a built motor for that.

 

as of right now I have my timing set back to 7 degrees, and a Boost dependent FMU and a walbro hi flo pump

no detonation right now.
bout to put in some 450 cc DSM injectors and the SMC fuel controller.
Then put in a BTC so i can run near stock timing and have it retard it for boost.
But with NOS, i'd probably upgrade to a hondata 2b w/ boost (or whatever the new equivalent version is, like s100 or whatever its called)

 

Why such a small amount of NOS shot. 20-30hp isnt that much epsecially on a boosted engine with the JRSC, you will already have good bottom end. Why not do a direct port setup where your going after the SC and TB. You will get a better result and not have to worry about damaging the teflon rotors in the SC. Im sure you can run a 50-75 shot and not harm your engine. If you want 20-30hp get a VAFC and or do some dyno tuning on your car, or get the ATI procharger for about the same price and make more hp than you ever will with the JRSC.

 

1. If he wants to run a bigger shot on top of boost, he's gonna need internals.
2. A 25-30 shot dry will significantly cool the intake charge, so he could see 50 whp just from that.
3. Dry kits don't damage the teflon rotors, just single fogger wet...the fuel damages them.

 

you cant run nitrous with a jrsc, they just found out it like eats the rotors or something.

 

i've talked to a lot of people online who have run the wet kit, saying that spraying the mixture which mixtures the n2o and fuel into the intake before the throttle body hasnt harmed their blowers since its only in there for a few seconds, and the corrosive effects of the gasoline on teflon cant happen then.

But then I've also heard that there could be slight residue from it left over which can damage it over time.

And I've heard comments of it possibly preigniting due to the heat of the pressurized air and the inside the blower.

But to contrast that last comment, i've also heard that spraying b4 the throttle body will let the mixture blend better in the JRSC manifold by the rotors.

I seriously want to get as much info as possible on this, all forms of N20 that would be possible, and each ones pros and cons with the JRSC.
I talked to one guy who ran a 30 shot wet kit, and ran a 12.8 with just the standard 6psi JRSC and 30 shot.
I would like to break into the 12's also this spring

 

I would not want to risk running a wet single fogger kit. First off it's very possible for the residue from the fuel to eat away the teflon coating on the blades, that is exactly what happens. Second, like you said, it's possible for the fuel to puddle, then ignite in the intake and cause a backfire...this is not good, especially with that blower. If all you want is for a cooling effect, there's no point in running a 30 shot wet, dry will get the job done better on a small shot.



Think before typing....

 

This here is just a thought... In no way to I claim to know how to setup nitrous, but I just thought of something that may or may not make any sense. To me, it seems that you would want the nitrous after the air has been pressurized, making it kind of like an intercooler effect. If you ran it before the super, the air will just get re-heated loosing some of the effect of cooling. And before the JRSC you may get the problems that everyone else was saying about eating through the blades, so it appears that you would want it after the SC for the most effect...

If that sounds retarded or if someone else already said what I just did in special nitrous lingo, my bad!

 

It still super cools the intake charge before it goes into the blower, so overall the temp is lowered inside the blower as well since you started with a lower temp.
