Hi, we are currently running a JRSC on a 00 Civic Si with methanol injection. The car is currently making 225WHP with a stock motor, bolt ons, 10psi and methanol. We were thinking about running a 35-50 shot of nitrous on this motor. My question is for anyone who has ran a JRSC and Nitrous. What type of shot should we run? dry, wet, direct port? And if we run a shot of nitrous, can we spray the motor with methanol and nitrous at the same time or should we disable the methanol when we spray nitrous? Thanks for any replies.

 

i would say direct port. Becauserunning nitrous pre-supercharger, i would think that there would be delivery issues, such as pooling, etc

 

Direct port is useless with a blower. I would just run a 35 wet shot through the blower.

PM gitwidit, he sprayed on his JRSC d-series.

 

thanks, i was thinking a dry shot would work, just run enough injector for it

 

do a nx 35 wet kit

I'm kinda iffy about spraying fuel through the blower

 

i used a wet kit, put the nozzle about 8in before the tb. with a 17 shot i gained about 25-30whp.

sp you sprayed fuel through the blower?

 

i see no logical reason why a direct port setup would be a waste on a blower car? that just doesn't make since.

now dont quote me, but i dont think it's good to run fuel through the blower. there was some information floating around on the net that was saying that fuel will eat away at some coating on the blades of the supercharger.

some people say that nitrous gives the intake charge a "cooling" effect. now personally, i think a strait direct port will make more power because of no phase change and what not. however, i do think a cool setup would to go direct port on the fuel side of things while using a single fogger in the intake tube. just an idea

 

yes i sprayed fuel through the blower.

 

Numerous people do it with no problem.

 

There is a lot of fear surrounding running fuel through the blower, but the bottom line is that it's been done in the domestic ranks forever. Running monster M112 blowers with dual carbs is commonplace in the old school hot rod and musclecar circles.

With that said, I would still stick with running a 25-35 dry shot through the blower, and going with additional fuel through the injectors. Be sure to spray as far from the TB as possible, as to take advantage of the cooling effect in the intake tract, TB, manifold, and blower. I don't have any insight on the methanol with nitrous. Although I will add that the top fuel guys do it all the time. Then again, when they blow, they blow good.

You're going to really like a small shot on a blower.


Also, are you running cam gears?
If not, get some. I went from 220whp and 138lbs of torque to 239whp, and 158lbs of torque on my b16/jrsc setup, tuned with Hondata. That car was a ******* beast, eating 600 cc streetbikes from a roll like they weren't even trying.

I think thats what we are going to end up doing, a dry shot seems to be the easiest and safest way to run j00ce on this car, just up the duty cycle on the injector and we should be fine. The car does not have cam gears, the motor is bone stock, only has i/h/e, jrsc and methanol. thanks for the replies

 

im runing a JRSC setup in my b16a2 with the stage one of boost upgrade from JR.. would i be able to add some nitrous without having to change inyectors and stock ECU. What about cam gears r they any better without ECU tunning.

thanks

 

Nice. Danish man, you always post good vids. Post up some video's of your 2000 em1 with the jrsc for us man.

if you are running stock injectors and stock ecu, i would wait till you upgrade before you think about spraying the motor. Buy a set of DSM 450's of ebay for 100 bucks and get hondata, then think about spraying. You shouldn't look to use nitrous unless you are maxxed out on the setup that you have. &lt;----Just my opinion. If you still have stock fuel pump, injectors and ecu, I would worry about upgrading those first before you think about using nitrous oxide.

 

thanks... i have a walboro 255hp fuel pump and thats it. stock inyectors, ECU.....
so theres no way i can spray with this components being stock. no even a 15hp, or a incognito system.
The thing here in Mexico is sport compact tuning is very rare among mechanic shops so we don't have people that would put your car on a DYNO and tune it for you lets say a HONDATA or some other EMS.

 

Try to contact matt or doug from hondata theyll help you alot. Ive also asked them the same question and to get the most from the N2O they suggested using a dry n2o setup and have HONDATA control the extra fuel. good luck

I used to run a 80 shot single fogger wet on my sohc del sol. Then I ran a direct port setup on the car. Direct port is the safest way but it is hard to jet it for lower HP levels. (i.e. 60 or less). I also ran a single fogger wet (30 shot) on my CRX when it had a JRSC blower - stock GSR - 7 lbs of boost. my crx used to pickup 5 MPH and .6 et with just a 30 shot. probably the simplest way to go on your setup.

 

Stock inyectors and ECU?

 

had 310s in the del sol with a vafc, 450cc and PMS on the crx

do you think a dry shot and running more duty cycle on the injectors would be ok? I am not too familiar with fogger setups.

 

I'm sure that it will work. I was just listing what I had used with success.
