I did some searching and found some answers but wanted some more opinions, I have been doing HPDE's for about 3 years now and am looking for some more power. As some of you know I have an imported CTR and just installed a Spoon 1.8 liter kit(not looking for flames on that I got a good deal) But I am thinking I want to go with a JR Supercharger, The car is nearly a dedicated track car at this point and I have a good tuner and hondata s200 but would change if needed. Just looking for opinions and suggestions on this setup and motor basically an ITR motor in a road course enviroment. All opinions welcome. Anyone out there doing this with success?? I am sure heat is going to be my biggest enemy especially living in Arizona. Please dont flame me too hard and I really dont want to hear keep the Type-R N/A the way it was intended. Thanks for all input. looking for 230 to the wheels does that seem like a realistic reliable goal??

Also anyone think a turbo would be a better choice? I want to make it clear that I am not looking for outragous power just a little more kick.

 

230whp shouldn't be a problem. A good friend just put down 230 with a JRSC B18C1 at 10psi. The Hasport guys are in the AZ area and have a few JRSC cars that kick ***. If you have the $$$ do it right and get the LHT intake manifold for the JRSC, it will keep your intake charge temps way down and you'll be able to run more boost. A nice radiator will be important also. Good luck and have fun

Yeah I have worked closely with the HASport Guys on many projects and yes they do kick ***. And I have also been looking into that LHT manifold it looks like a good investment and I will probably go with it. Thanks for the response

 

Contact Batoutahell. He had a JRSC ITR that he did a lot of lapping in. He can probably provide a lot of insight.


Also contact rmcdaniels. He is a local guy that is using the LHT intercooler with success on track. Here is a link about his set-up https://honda-tech.com/zerothread?id=1518026

 

Yep, big radiator + either low boost or some kind of water/alcohol injection and/or the LHT intercooler dealie. There are a few other things that help out a bit with temperature issues, like an Endyn ported S-tube. I'm not experienced with these things at all, but I've been doing a ton of research lately and talking to lots of knowledgeable people (been thinking about throwing one on the track car as well). Also be prepared for slipping or broken SC belts, like, bring a couple spares. It won't hurt anything if it breaks, but it'll be annoying.

 

I was never satisfied with my turbo setups for track days, with the possible exception of the dual sequential turbo/super setup, which was really insane:

I really like my current setup, which uses a high compression motor and a small amount of boost from a JRSC. We made a hair over 300 WHP on 8 PSI of boost with intake temps that usually didn't break 100 degrees. I've only had it to the track on one day at VIR, but it was raining and about 33 degrees, so I really couldn't push it too hard and heat wasn't an issue. I'll be back at VIR on April 8-9, hopefully in better weather, and I'll datalog some laps. I daily drive the car (It's my only car), so I do get a lot of seat time with it, and the setup is working very well so far.

As far as performance goes, it's great to have the extra torque delivered so smoothly anywhere in the RPM range. The car pulls much harder, the power is easy to control, and I have a lot more flexibility because so much more of my RPM range is so much more usable. It's nice to be able to not downshift because I have bunches of torque at 3000 RPM.

I'd definitely consider getting the LHT manifold, John has done a great job making a functional intercooler for the JRSC:

Also look at getting the blower ported, Wynn has been porting Eaton blowers with excellent results for a long time (he has an M90 of mine that he's going to perform some serious surgery on to make it work with a JRSC):

Yeah, I've taken over testing of the twin charged set up and it's really incredible!!! I'm running a different turbo set-up, a lot smaller turbo and a liquid intercooler. Still working out some details but when the car is running it's so much FUN

Thanks Roger

 

Anyone else with experience with a JRSC on track?? I really appreciate the comments and suggestions. Thanks Again.

 

When Expo5 was at MAM last summer I made the trip up there to ooogle and I saw a few if the ITRs up there had SCs on them and I think one had a turbo. Not sure if they ever post in here or not though. Might want to make a post in the ITR forum just to see if they are in there.

 

Good Idea I will give it a try.

 

Can't speak for the B18C5, but I'm loving a turbo on my LS... the JRSC is pretty weak on B-series motors, and the power it gives you at low rpms is useless because you're going to be limited by traction anyway. With a small, quick spooling turbo, I have plenty of power ready and just waiting for the front tires to have enough traction for me to floor it. With a higher revving engine and/or larger turbo, that may be a different story though. Roger's setup with the JRSC for bottom end and a larger turbo for top end seems like it would be pretty cool though.

 

I've piled on some track miles in my (formerly) jrsc'd ITR. It made 230whp at a modest 7psi. I never felt the desire to crank up the boost any higher. Many of the events I attend are in the midwest, often in 100 degree heat. I never did measure intake temps, but the car never skipped a beat. I've heard good things about the LHT manifold, but I never felt the need to cool the intake charge at only 7psi.

Power delivery is very linear and easy to control. It would take a deliberate throttle input to upset the balance of the car in the corners. I raised my rev limiter to 9200rpm because the jrsc just kept making power. If I had an upgraded valvetrain, I would have raised the limiter even higher. There's something to be said about the fury of 9200 rpm in a jrsc'd b18c5, it's almost cathartic.

My kit was pretty much bulletproof reliable. I never snapped a belt, and never had a belt slip on me. I'm not sure where the rumors come from, but of all the jrsc'd integra owners that I knew from hostboard, I can't recall a single belt failure. That's not to say it doesn't happen, but I think the urban legend gets blown out of proportion.

I have never tracked a turbo car, so I can't offer a direct comparison. However, the most satisfying part of the jrsc on my ITR on the track is that it didn't upset the car's overall balance. The increased power was very noticeable, both on the straights and on corner exit speed. However, the increased power wasn't overbearing in relation to the rest of the car. The linear delivery of power and a bit more torque down low felt just about "right" and in proportion with the rest of the car. My most fond memory of the kit is that it really complemented the character of my car.

Sadly, my R is up for sale and all the mod's have been removed for sale. I just hope my jrsc finds its way under the hood of another track-ITR.

 

Thanks alot for that post it really is making me think I am going supercharged. Once again appreciated

 

Didn't notice the S/C R's on track at Expo 5, but there was a boosted GSR, he had to pull off every couple of laps. Never saw any of the S/C ITR's pulling in to cool off. That should say something.

Yeah it says one guy with a turbo didnt have sufficient cooling and/or other problems, but you dont have any details on any of the cars out there so there is no way to make a determination about which setup is better for cooling and/or why.

 

Yeah, he was on a stock radiator I think.

Chris F was fine in his turbo R, though his oil temps were getting up there (heard him talking in paddock).

The S/C R's were all JRSC I believe, bolt on kits with stock cooling systems is what I saw from walking around in the paddock.

That'll do it, I couldn't make it one lap around Roebling Road with my 408 WHP turbo B16 on a stock half-width dual-core radiator before it got too hot and I had to baby it back to the paddock. A Fluidyne half-width radiator (swapped at midnight in the Holiday Inn parking lot) fixed me right up though, temp went to 160 and never budged, even running it up to 160 MPH in the straight stretch.

 

does that mean you are going to get that pos back on track soon?

If you want, we can chat sometime about my JRSC experience. Although, it was more boost on a street Prelude.

 

Yes this means the POS will be back on track soon.
