Alright, tried the search to no help. Just need a simple answer and maybe a little help w/ what I would need to make it work. Is it safe to run a small shot (30-40) on a 00 Si w/ JRSC? Would the gains be the same as a stock engine?

 

You cans use the Nitrous without problems, the best goal is the cool of the JR

 

I have done this to at least 5 si with a jrsc. One of them being my best friend. you can run 10psi then a 40 shot with -2 retard on your ignition timing if you get a jerk when you hit nitrous just retard one degree etc etc. Oh make sure your cooling with a liquid injection if you run 10psi.

 

I'm only running the regular 6psi on the JRSC. What does this mean for me? And what size shot should I be looking at?

 

damn I would get the 10psi pulley and run boost that way your block takes this swell I have even done 12psi with a good liquid injection. If your just running 8psi make sure you get liquid injection for heat purposes and then shoot the SOB up with a 50 or 55 shot and retart the timing at least -1 for sure and if it jerks when you shoot (believe me you will know) touch it down to -2. Careful with nitrous jerking is detonation and you know what this does to your motor. Let off right away if this happens. The key here also is check your plugs often if your seeing a cloudy looking tip on that plug richen it up a bit, if your seeing a wetish/oily lookin plug your running rich which is good but remember if your smelling gas on this dam thing i mean like bad lean it just a bit. And also nitrous does a number on your plugs so check your plugs on your first runs and replace them if you see melting. Then If you love your motor change your plugs after every bottle.
Never get hot plugs and dont get really cold plugs either because you will just foul them.

If you do this all right your motor will last forever. Oh yeah if you can get a block guard this always helps..

 

Is bumping up the psi as easy as just getting a higher psi pulley? I was thinking of going 8, but would that make daily driveability any different?

 

believe me supercharging is easy its not like turbo where it pulls hard (like I like it) but like a mild boost. And only at your top end will you run a full 10 psi. Yes it is just that easy to upgrade buy a pulley set it comes with a belt. just make sure if you run 10psi you get liquid injection for the fact that the (edit) supercharger needs cooling. If you run 10psi with hot air your just asking for trouble. I would recommend liquid injection with 8 psi even. Most cases you gain HP for the fact that it cools your air. Cool air= Dense air= More hp. Jackson racing superchargers are only designed to boost so much, then the blades touch. this does a number on your motor too. boosting 10 all the time is no problem. I do this upgrade all the time.
This is the reason why I own a turbo boost gain is no problem full boost also comes in soon.

Alright, so lets say I bump up to 8 lb pulley. The car dyno'd at 190 whp w/ the 6, any idea of the amount of gains I'd see? I'm picking the car up next week, have to fly to TX from MN and drive it back up here

 

depends on if your cooling with liquid injection. it would be like 10-30 whp depending on tuning and cooling, air temps. but you would feel gains on the pedal easily.

 

Now this is going to sound very newbieish...what do you mean liquid injection? Replacing the stock fuel injectors? Thanks

 

You guys are talking a lot of boost and nitrous!! I would run 6-8lbs max with a 25 shot of nitrous. In a bone stock GSR i've heard of people running mid 12's with that setup and slicks.

Why would you guys recommend liquid injection with nitrous? That water you are injecting is just less space for air, fuel, and nitrous to fill. How much cooler can you get than nitrous? I would stay away from liquid injection unless somebody has proof about horsepower gains.

Liquid injection is just water or a water/alcohol mix that is sprayed into the intake stream after the blower to cool the intake charge.

By the way i am assuming that this is a stock motor. I might have missed something.

 

liquid injection is a waste of money compared to the price/gains. the Nitrous will yield a better price/gains ratio and it also wont cause the possibility or rusting the manifold with the water.

 

Well heres a list of the major mods besides the SC, think a 25 shot on the B16 would be worth it?
Jackson Racing Supercharger @ 6psi
Comptec FMU
Holly Fuel Pump
AEM Cold Air Intake
Kamakaze Header
Thermal Stealth Exhaust
Clutchnet Stage 2 Clutch
Apexi Vafc
Autometer Boost & Air Fuel Gauges

 

apperantly I have to explain all of this to you..

Liquid injection is a pump connected to a water tank filled with distilled water and or alcohol. injecting liquid into you intake piping before your TB. Now how this works is like ex(hot day, rains all of a sudden, that foggy stuff coming up off the ground is vapor) Ok this only happens when water suddenly hits something hot AKA hot intake air. This effect (vapor) cools the intake temp of your supercharger. Now like Stated before Cool air= Dense air= More hp.

Now is liquid injection worth it? Hell yes, why, when you have a supercharger you dont exactly have a FMIC, right. besides even if you did it would do you any good. Because heat is generated by the supercharger itself. So if you liquid inject its vapor, vapor cools the air and you intercooler. If you push 10 psi non liquid injected on your JRSC your going to see detonation and excessive supercharger heat. This is the same as running 7psi non intercooled on a turbo. oh by the way your manifold is aluminum it doesn't rust. so is your block exept the sleeves. If anything the liquid injection will clean the top of your pistons with vapor. This does happen too every motor I have opened with liquid injection looks clean inside.

Also it doesn't matter if you run liquid injection its not going to take up excessive space with combustion. remember the colder the air, the denser it is making it smaller. Nitrous will only contribute to this. And yes liquid injection works, I have customers with JRSC gain at least 10-20 hp with these. and no they are not expensive as they say yes its a chunk of cash but at $250 who can complain about the gains..

I have done two cars with a 10 psi pulley and 45 shot/w liquid injection still running and working after 50k, compression tests are done every other month. the all check out fine. Its tuning that counts in this instance. they also have block guards. People tell me im crazy I again have proved them wrong. As long as you have no detonation you'll be fine.

 

In my opinion water injection is a waste. There is no need for it when you use nitrous! The water just takes space away from fuel/air and nitrous. If you say it doesn't where does it go? I'm not looking for an argument thats just my opinion.

I would use the JRSC @ 6psi and a 25 shot of nitrous. Then if your not satisfied try somethin else. More nitrous or water injection. I think you'll be happy.
