I had a NOS kit installed with a 40 shot of NOS last week. Today some dyno tuning was done on the car. I currently run 9.5-10 psi of boost and 215 hp at the wheels. The first pull with the NOS, the car hit 300.4 hp at the wheels!!!!!!! A/F ratios looked good. I'm running a MSD window switch with a range of 3000-7800 rpms. It really seems to compliment the SC. It made great power but I think that is too much on the stock internals and since I'm not ready to build the motor anytime soon, I'm going to see if they can detune it down to 260 hp. Some adjustments were made and then the next pull on the dyno was underway until the SC belt ripped. Is there a way to measure intake temp??? Do they make a gauge for that??? They make exhaust temp gauges, can those be used on the intake side???
I know the JRSC isn't perfect in the eyes of a lot of people. From what transpired today, the biggest issue is getting that intake temperature down. Why doesn't JR have an intercooler of some sort for their applications???? I think that water misting thing they sell is hype. Well, I just wanted to share my experience today, feel free to respond with your thoughts.

 

They do not have an intercooler because there is no practical place for it to go. Their blowers are part of the intake manifold. Even if you could fit a miniature intercooler in there somewhere (enlighten me as to where), it would be in a terrible position to cool anything.

And yes, they do make intake temp gauges. Greddy makes some as do other manufacturers. However, It would be hard to position the temp probe in a useful place on a JRSC integra. The temperatures you want to measure are AFTER the blower, and you would have to drill yourself a nice hole in the intake manifold which is probably a bad idea. That, and the probe would be likely to be influenced by the high temp. of the intake manifold which does not necessarily reflect that of the intake air.

Yeah, that is a problem Dustin. I guess I'll keep the blue bottle in the trunk, plenty of space there.

 

Jackson Racing has confirmed that they ARE making an intercooler for the SC. I and a few other people have spoken to different people over there that said product development and testing were under-way. Priority was said to be for the DOHC motors (I'm assuming the B16 and B18 first, before the CRV and Prelude engines). I have a SOHC engine and they said that they have not ruled out making it for the SOHC but it will be second in line. They are claiming a release of about 1-1-1/2 years. With Jackson that will probably equal 3

 

Cool forced induction engines with our Liquid Intercooling system, instead of losing power from retarded timing.

Don't hold your breath... heh.

I know third parties are working on a intercooler also. They have had a prototype for about a year right now. they are currently working on trying to make the intercooler bigger so it is more effective. But the current one works!!!

The water injection works but a intercooler is better!!!

you should be about the jet the NOS for a 25 shot

k

 

I've used a single fogger (rather, a converted direct port nozzle) jetted to 25 shot on JRSC cars and typically see gains of about 40-45whp and 50ft.lbs. We set it up so that the fuel/no2 shot directly into the throttle body, thus mixing & distributing the mixture evenly, and cooling the supercharger at the same time. We could make a full throttle fourth gear run on the dyno and the charger would be cool. A full throttle run down the track in 110 degree weather resulted in a ice cold blower. It's my belief that not only does this make more power, but also extends the life of the blower at high boost levels (10+psi)

 

215whp with 9.5-10psi is pretty low. Should´nt you pull 230-240whp with a propper tuned GSR on 10psi?

 

i'll agree with the austrian on this one. i had a 8lb pulley and pulled 225 to the wheels.

 

agreed. I've had 6psi cars put down 225 to the wheels with I/H/E and a full functioning cat with the JR fuel hacks. But most averaged around 210-220. A 10 psi car should be around 235-240

 

I've always thought my dyno at 10 psi was a bit low. If you guys would like to take a look at my Mod list, click on the link in my signature. I'm interested to know what you guys think about my mods.

 

Looks good...I would personally lose the wheels and go to some newer 6spoke gsr wheels...also are those clear taillights? My last setup was B18c with 8.8:1(too low) compression and the JRSC @ 13psi hit around 275 whp. I definately went with the wrong pistons on that setup.

 

What kind of pistons did you have? also, there is a buddy of mine here in town who has SRP 9.0:1c/r pistons for my motor, are they the same as the JE pistons, or are they a cheaper version?

 

Yes, I had clear tail light lenses on the car but swapped back to the stock ones. I bought the Lenso VPD rims because they are light weight....16 lbs a piece which isn't bad for a 17" rim that cost $160 each. To my knowledge...SRP and JE are the same company, correct me if I'm wrong.

 

They are the same however the pistons are made of different casts. JE's are stronger.

 

The IC has been in development, and was scheduled to be released in about 6 months, but it has been put on hold as of this point due to other product developments that need attention. Some JR distributors are trying to figure something out to get the project back up, but as of now its on hold.

There is one 3rd party developer, and his IC is coming along nicely IDEALLY, but we'll just have to wait and see. It would be sandwiched in between the blower and manifold, which is a tight fit as it is. Water Injection is crap, BTW

 

i would advise u to stick to the 40 shot, have them tune it for safety and get the pully for 8psi instead of 10, then u should make about 260whp on juice, and still make 220 w/ out..

220 does seem low to me, my friend had AEM CAI, DC header, greddy exhaust, ITR cams, and Vafc, he made 220whp at 6psi and then they played with the vafc, timing, and got 230whp..

are you still running a catalyst? If so, ditch it. Also, the AEM is probably too restrictive for the blower, I like the 3inch cold airs (generic is fine) or an Iceman. There should be around 10hp between the two.

 

Hi John, no the catalytic converter has been removed and I have a test pipe in it's place. I am running a AEM short ram air intake because after some research, it is supposed to be better for the SC application. The longer intake tubing on a cold air setup resulted in less air travel into the motor versus a shorter air intake. I obtained this info some time ago from Endyn and if you notice what JR sells as their intake, it is a short ram air intake.

 

Do you like your super charger? I am think about getting one (actually I want one bad! It almost keeps me up at night!). With the mods you have, is it easy to get tuned, or is it a pain in the ***? Does anyone know about how my Jacobs Electronics stuff might work with a JRSC?

One last thing, does anyone else make a super charger for Hondas?
TIA

 

funny thing is, I know of a few people who bought a radio shack thermostat, ran the probe to the intake, and mounted the panel somewhere on their dash. For $25, you really can't go wrong....

Its not just the length of the intake that helps, its also the diameter as he says. 3" piping is what youre looking for. A generic 3" short ram can be bought off of ebay for like $50.

I like the JRSC. Its nice having a mild mannered, quick daily driven car that has great throttle response and can roast the streets when needed If you want all out power though, I would absolutely recommend a turbo. Dont go with Jackson expecting to run 12's unless youve got some serious cash...at least not yet at least.

Vortechs centrifugal SC should be out soon for the B18C1, but its all high end power. If you want that, may as well get a turbo, especially with Vortechs pricing.

 

Damn... are yo udriving a car or a plane? look at all those gauges! how do you know how much gas you have left or how fast your are going!!!
