I have an B18C5 Engine running a JSRC at 10.4 psi making 223 whps. My Manifold is leaking coolant due to the previous owner doing a bad job drilling the holes. My manifold is a GSR.

 

Soooooo...............Are you asking something here or just telling us some stuff?

 

Looks like he was trying to find parts but Tech8 edited his post.

 

Just wondering what results are other people getting with there superchargers

 

General consensus on these was always that they weren't worth the added cost and reliability issues compared to a well built NA setup. Full disclosure I've never owned one of these kits myself, but I've consistently seen them get relatively low dyno numbers that would be attainable NA and have manifold leaking issues like you're describing.

For the B series both the ATI Procharger kit and Kraftwerks kit are much better options.

 

I believe they are pretty valuable for nostalgic people. I'd sell it and put that money towards something else

 

Jackson Racing superchargers are great for auto-crossing since they have immediate throttle response and low end torque. They aren’t preferred for drag racing because they are limited in total horsepower output. Most people I’ve seen with these superchargers are maxing out around 300whp at most, and most people are in the 200-300whp range, although if you have a good All-Motor type set up with a supercharger added on that, you could push over 300whp, but I don’t think more than 350WHP or 400.
If you’re just going for a 13 or 12 second time in the quarter mile, then a supercharger is good too.
So it depends what type of use you want out of it. It could be useful for smaller track road racing too.
Here’s a super long thread about them:

I don't think I've ever seen anyone push over 270-280 on a B series JRSC, and if I remember right the guy pushing those numbers had a lot invested into that system and did a lot of extra things to optimize it. Most often I see people making anywhere from 210 -> 230WHP on these kits, even 240+ seems very rare.

I'd be interested to see if anyone has ever taken these over 300WHP, it's been a long time since I've looked through the thread you linked. I could be wrong as I'll admit this is entirely off speculation/observation.

 

They are pretty good superchargers....for what it's worth. Making big numbers isn't what they're known for.

 

I've never seen a supercharger make big numbers on a 4 cylinder.

 

I've seen a few Kraftwerks supercharged B and K engines make good power in the 400-450 range. I was strongly considering going supercharger instead of turbo when planning out my hatch, but wanted to retain AC and the Kraftwerks kit mounts where the OEM compressor goes. The Procharger kit may have worked well for me, but ended up going small turbo for (reasons).
@wunfastgsr Has a really nice build, pretty sure he's been on the ATI Procharger for years now - don't remember his WHP results but it's a really nice car.
@JRCivic1 Also has a lot of experience with supercharged Hondas.

 

Keep it how it is. And add a turbo kit it to it. Thatll give it the beans for sure

 

It's been a really long time since I've seen anyone try a twincharged build.

 

Dont think ive seen a successful one completed. Before i joined in 09 at least. Didnt notice anything prior either. Would prolly be rad though

 

Wasn't common but was common enough with 03/04 Cobras to know it works. Twin screw/roots helps get it going with torque and then the turbo takes over.

Power limitation comes with the supercharger/intake setup restricting the turbo over a normal intake.

 

Well that sucks. But makes sense

 

So in 2005 I actually ran a Jackson Supercharger on a sleeved 10.5:1 compression motor with fully ported head. I had Endyne port the supercharger and I even ran the LHT Performance Air to Water intercooler setup for it. My setup made 280WHP BUT I hated the performance. Even with the LHT intercooler the car had horribly high IAT temps and would heat soak, my LHT Performance intercooler would always leak and had to be fixed by John at LHT multiple times.

The best QT I was able to put down was a 12.8 with this setup and altogether the setup cost me damn near 5k, I ended up selling the entire kit to a guy in England for $3,500 bucks and was happy I did so. At the time I found a guy selling a little Garret 57 trim turbo kit with ram horn manifold for 1K. This kit came with everything, intercooler, piping, wastegate, blow off valve etc. After I installed the kit, I took it to get tuned and made 480whp with the setup, went to the track and ran an 11.6 first time out with it.

From there on out I never looked back LOL..

 

Yeah that about sums up every other experience and result I've read from the JRSC on our cars. It's too bad the ATI Procharger kit never got more attention for the B series, wunfastgsr seems to have had extremely good results with his and overall it seems to be a much more capable kit than the JRSC while still retaining factory comforts like AC.

Kraftwerks has the most power potential but (completely anecdotal) I heard from Jeff Evans that those units are prone to some problems of their own in our cars and he's had multiple customers who have to send their superchargers out for rebuilding every ~5K miles

 

I remember people back in the day also using the Procharger Kits and they had tons of problems as well and needed rebuilt all the time.

 

I know apples to bananas but I believe superchargers on K series are pretty successful though right?

 

S2000's F series engines seem to have good success with the Science of Speed, Vortech, and TTS(?) kits as well.

I think even where, or specifically how high/low the supercharger is mounted relative to the rest of the pulley system even plays a factor. And then of course you have to consider belt grip, grooves, widgth, etc. Been awhile since I've looked into superchargers on these cars, they seem cool but turbo is the path with more footwork and documentation behind it.

 

When I had my JRSC w/LHT cooler I was making 290whp at 13psi.

 

What engine build/bolt-ons/fuel?

 

Mine made 297 WHP without the LHT Intercooler set up... best 1320 was 11.55 @ 118mph. This was in late 2001.

 

Rebuilding a Rotrex ? I don't believe this is a thing. Last I spoke to anyone who sells/represents them, no rebuild is available from Rotrex. You simply have to buy a new one when you have a failure. Interestingly, the shop that did mine is well versed with the Rotrex based supercharger and has NEVER had a supercharger failure... and they have some customers who road race with them. I wonder what they are doing that other shops aren't to resist/eliminate failure ?
