Question JC Sports Super-Charger Kit

I see that JC Sports is now offering a super-charger kit for the 2.5RS. It looks exactly like the Rimmer kit. Does any body have any information about this kit? Has anyone installed one yet? Any input would be greatly appreciated!

It looks like the rimmer kit cause it is the rimmer kit, they even cut and pasted the description for the kit off the rimmer page!

Actually, it's not the Rimmer kit (from what I've heard). The only thing the same as the Rimmer kit is that it uses an Autorotor blower.

GTBGUY - If it isn't the Rimmer kit, they should take new pics and write new text because as it sits now, it IS the Rimmer kit by looks and by text (very obviously).

Yup, I know, that's what I told them on the phone too. I guess the only reason they have it like that for now b/c they haven't gotten pics of it yet.... but the pics are only for the Tiberon.... there aren't any pics on the Subaru kit yet.

Why is it that 8psi of Supercharged boost is predicted to produce 230HP. Aren't 8psi turbo systems producing more max power than that? Whats the difference?

I hope this kit is intercooled and comes with some kind of engine management.

Question

I sent JC an e-mail asking about the kit but I have not recieved a response yet. So, nobody here has installed this kit yet?

Exclamation

The reason the super-charger doesn't make as much power at the same boost level is because a super-charger takes power from the crankshaft to run it. I believe at 6000 RPM and 8lbs of boost it takes approximately 30 HP just to turn the super-charger! A turbo uses wasted power from the exhaust stream.

The kit is brand new, they have not instaled it for any one yet...last time I talked to them. it is not the Rimmer kit, it should be alot better than the Rimmer. it only makes 230 becasue Super chargers are not as good as turbos at making peak power, they use power from the motor so they make less total but they have no lag and a steady boost level, it will ake 8psi whether you are at 1500 rpm or 6000 rpm

@ 8psi only 230hp simply b/c of decreased thermal efficiency vs. using a turbo.... torque on the other hand should be equal or greater... but definate @ lower rpms, the S/C will have more torque.

Default JC Sports, if you are reading this

If someone at JC Sports is reading this post, I have a few questions about your super-charger kit. Does the super-charger run off of one of the exsisting belts or do you add an additional belt. Is a RRFPR included? Is a "voltage clamp" included for the 2000 model year? How big is the intercooler? How long is the warranty? Is the lubrication self-contained or does it use the engine oil pressure? If it uses the engine oil pressure, do you have to replace the oil pan for the oil return line (GOD I hope not)? Is the throttle plate moved to the INTAKE side of the super-charger like it should be? Is the cruise control still retained? What is the availability of this kit (are they in stock and READY to ship)? Have you dyno'ed an RS with this kit installed yet?
If this is a good quality kit, I think you will sell a whole bunch of them!

I believe it is 230hp with just a rrfpr and stock exhaust.....

I bet with this supercharger kit, headers, high flow cat, catback exhaust, and some descent fuel management with bigger injectors it would probably near if not the same as a turbo.

You loose almost as much hp off the exhaust as you do with a supercharger feading directly off the crank. I bet if someone made of full set of mandrel bent equal length headers with a collector, you could make as much hp and more bottom end torque as a turbo...

They both have there advantages and disadvantages, just nobody has taken a supercharged car as far as it can go yet.

I still like the fit and finish of aftermarket turbokits better as of right now though.

I am looking closely at both the top Turbo offerings, and the future S/C offerings...

for the money a Turbo is a better value I think... But for the power I am going with a S/C.

Low end power is where all the fun is anyways Also, I bought my 02 2.5RS to be unique compared to the flood of Turbo'd WRX's. So I think a S/C 2.5RS with more Torque and power than a WRX is a VERY cool thing I love sleeper cars.

Low end power causes you to be able to do scoobnuts. http://8complex.mwsoc.org/scoobnuts.html

a wise man that I know who works at GM out on their black lake doing test driving ( coolest job on earth ), told me "All the fun you are going to have comes between 0 and 100Mph.. after that you just hold on for the ride"

I believe being able to tear off the line, or having a nice punch at the low end with no lag is FAR more enjoyable around the city ( which is where I live and drive the most) more than the peak RPM HP out on a freeway.

What kind of gearing and power do you have where the lowend gets you up to 100mph!!!!

Trust me. Low end gets you moving, top ends gets you to 100mph.

P.S. Because of certain dealings(I won't get into it since I don't know much about it), I'm under the impression JC sports is no longer allowed to post pretty much anywhere on this board.

I've given up on an S/C, and have since started the wheels turning on a Turbo...

Question not Rimmer?

if that's not the Rimmer kit, then the have to be trying to make it look that way.

What's the cheapest that someone could expect to pay for a NEW supercharger? A Vortech s-trim is around $1500, if I'm not mistaken. Is there something cheaper? I can't find prices on roots-type units...

Default Hey RAO

Hey RAO, don't you have one of Rimmer's super-chargers on your car? I may be mistaken though...

I sure did.

Do a search for rao and Rimmer and you can read all about it.

Short version - it was a complete fiasco, poorly constructed parts, no testing or even assembly on a similar car was even attempted. The car never ran properly with the blower and no one could determine why, especially Rick Rimmer.

Anyone who would buy anything that Rick Rimmer is involved with an ANY way is going to be quite unhappy.

Note that to date (more than 1 year after my sad story) there are maybe 3 cars on planet Earth that have a functional Rimmer Autorotor supercharger system - and I have never heard of ANY MY2000+ car that runs with Rimmer's junk. ANd of those cars that run, the "kit" supplied by Rimmer was only a starting point.

And, yes, he still owes me a substantial amount of money, which has he has promised to pay many times (as recently as 6 weeks ago), but he has never paid one dime. I believe that there are others ono the board to whom he owes money as well, but they would have to give you the details.

My only delaings with JC Sports involved me ordering some parts, waiting 8 weeks and cancelling the order.

The thought of those 2 together is really scary - really.
