Just like the title, whats the most you've actually sprayed through your JRSC in front of the throttle body, I'm up to a 70 shot and am thinking about bumping it up to an 80, maybe more, what do you think?

 

 

Is it bad to spray through an Eaton/Roots blower?

 

if you have the internals to do it keep going!!!

 

I was thinking of nitrous myself do you have a wet, dry or fogger set-up.

i was taught that spraying with FI is almost like doubling the shot.. 70 shot = 140 NA shot..

that seems a lot to me.

bump for anyone that has experience with a wet system on a jrsc

 

I would like to know the answer to that myself. I am toying with the idea of a DP setup on my car over the winter with some internals. BTW its a JRSC Si.

Depends on how much boost you're running. My friend just cracked the rotors on the blower of his 2001 Lightning while he was running 20 PSI and tried to hit it up with a 125 shot. I think you'll be fine with an 80 shot just running 8-10 though.

I use the hondtaa nitrous controls, sprays dry in front of throttle body and hondata pulls timing and adds fuel.

I've got the internals and low compression to keep playin, just don't know how much the charger can take, thanks for the input everyone.
Going to try Direct Port this winter and let the hondata control it..

cool! thats some serious thermal stress. making 20psi with a roots blower is a very high temperature affair, and then throwing sub-freezing nitrous at it...yeah i could see that thing failing. as far as doing it on a honda. man 80shot is a lot...but hondata controlling fuel and timing - thats cool.

 

you might want to list your internals so we can help you and determine if you are reaching your max with the setup. You have a good setup from the sound of it and seem to know what you are doing. good job

 

Setup:
D16Z6
JRSC 10-11 psi
Hondata S200B tuned by Payn Technolgies on nitrous
Arias Pistons- 9:1
Crower Rods
STR block Guard
Balanced Bottom End
Clushmasters 7 lb. Flywheel
RPS 4 puck clutch
Refreshed factory head (New springs etc.)

I have around 15,000 on this engine now, think the bottom end can handle more nitrous, just don't know about the impellers on the blower. Am I the only one spraying these mugga's down or what?

 

You shouldnt have any problems spraying even a 125 dry shot into the rotors. Its actually cooling them down so that is helpful. Overspinning the blower is much worse. I call my nitrous setup a liquid intercooler for the blower

So how much are you spraying through your TRD blower? How much have you heard of people safely getting away with spraying it through the charger?

Im spraying a very small shot in mine. Well i did, i blew my supercharger a few months ago. I didnt blow it with nitrous though, i rigged the bypass valve open to limit boost while breaking in the bottom end and it overheated the rotors.

I raced a kid in a white GSR with a JR blower on it, he said he was spraying a .042 jet with stock boost and it ran really strong. Ive talked to different people over the years and have never heard of nitrous killing a blower. Personally i would never spray a wet shot into the rotors for fear of pre ignition.

I have an N.O.S jet stamped 032 in there now which I believe is a 70 hp shot for my setup but I could be wrong. It's so hard to find a jet=hp conversion sheet for N.O.S jets, does anyone have one?

These are approximate hp gains.

HP Gain / NOS Jet Size

25 / .024
30 / .026
35 / .028
40 / .030
50 / .032
60 / .034
70 / .036
85 / .045

Thanks biggins mang, where did you find that at, did a search and came up w/ nothing. Called NOS, they said every application is different, which is true to a certain extent..

 

The NO2 shouldn't hurt the blower. You need to check out the "forced induction integra" forum at hostboard.com. There are a few jrsc guys there that spray. Since the NO2 has a cooling effect it almost doubles the HP gains with a jrsc. So if the engine is built to take it don't worry about the blower. I don't know which blower you have but 10 psi is probably about the limit. You may need the nawz if you want to keep moving up. Good luck, and let us know how it turns out.
