Hey guys.l I just called JR today and was told the Prelude SH kit is now on the market and available to order.

Cool!!!!!! too bad it's almost $4000 by the time you add in tax. Not to mention paying to get it installed!

Maybe when I convert my lease and purchase my car I can somehow finance an extra few grand in there somewhere...... doubt the banks go for that!

 

Make your own supercharger kit! I'll draw it up for you and you can make all the parts.........You'd be happier with an f-max turbo, and have money left to put gas and come down to San Diego........If you do buy the expensive JRSC kit, we'll do the install......

 

I'll install it.. gimme some duct tape and a welding torch!

 

the only problem with the FMAX kit is that it is NOT legal. In CA, it's just a matter of time until you'll need to smog your car, or get pulled over and nailed.

Also, the FMAX kit, like all other turbos, won't work on an SH. Once you hit boost, ATTS goes offline. I don't want to install somethign that will deactivate the system.

I'm sure a turbo would be faster overall. But the JRSC probably makes the car hell of fast. It's just a matter of how fast you want to go, for how much, and do you want to stay legal???

 

Dang man, where's your sense of adventure??? Install it yourself! From what I have heard from those that have them, the JRSC isn't that hard to install. You just have to take your time and do it right. No shortcuts, and make sure that EVERYTHING is in place and bolted down.

 

I may be able to fix your atts problem if you get the fmax.....I'll give you a hand or two if you'd like to install it yourself (JRSC). I'll do it for a double double.......

G-

How do you get ATTS to work with a turbo? I've talked to at least 2-3 people who had turbo charged SH Preludes and ALL of them had the ATTS light come on/system shut down, as soon as they would hit the gas and saw boost. I was told that it has something to do with the power delivery being somewhat sudden and the ATTS computer doesnt' like teh torque to spike. JR says that b/c the supercharger delivers constant torque across teh revs, the ATTS system doesn't shut off.

I used to have a turbo RX7 (second gen) and if you've driven a turbo car, you know how you mash the gas, and there is a split second of lag and then all hell breaks loose and the boost is comin'..... I guess ATTS senses teh torque spike and thinks something is wrong so it shuts off the system. The turbo won't break ATTS, but the system just shuts off.

the other explanation is that ATTS can only handle a certain amount of opwer and if you put too much power through it, it knows it's too much and shuts off. Given that most turbos, like the FMAX for example, make well over 240 hp at the wheels, they simply are too powerful. The JRSC makes about 240 peak, and some have said that is about all teh ATTS can handle.

what do you think? I don't KNOW, I'm just repeating stuff I"ve heard.

 

Sean thats totally true. The SH can not handle all that boost. I know this guy who has the FMAX kit on his SH. The ATTS light will always light up. For those people who have an SH, I suggest the Supercharger. You get speed and that ability to take corners like no other. Have a Supercharger Sh race on the freeway, and watch them going into corners and out. It will kick butt. And for those of you who think that I am being bias. I'm not I have a Base model. Just my two cents. Sean keep us updated!

 

Sean, I think you should be the JRSC "guinea pig" for the SH .

 

I know someone who finally got their car out of the shop after the JRSC was installed. It is pretty damn nice. They had some serious installation problems though. Not with fitment, but with how it ran. Timing probelsm and such. After speaking with JRSC they got it fixed. They are still having some tuning problems, but it put over 200hp to the wheels. Not sure on the exact number, but I wanna say it was around 225 or so.

Now too bad it will not fit in my Accord chassis.

Has your friend mentioned how the car sounds with the SC installed? I'm concerned that the whine of the SC might be annoying while cruising on the highway.

Also, any noticeable change to the handling characteristics with the extra weight up front?

To answer your question baustin9, contrary to what most people think, the SC is NOT boosting all the time. The boost only comes into effect when you are heavy on the throttle. During normal cruising, all boost generated by a JRSC is sent through a bypass valve, and NOT directed to the cylinders. Once you mash on the gas that bypass valve closes, and your JRSC starts to apply the boost.

If I am correct, there should be no whine during cruising, only during hard acceleration. Those who are more experienced, please correct me if I am wrong...

 

I'll be the SH test mule. Just send me your cash donations and once I have $3500, I'll buy one....

ONly 225 to the ground??? I thought JRSC "claimed' 240!

It would be nice to have all that power though!!!! I guess if you have 225 to the wheels, that would make the car somewhere around 250-260 at the motor??? Not bad. Not turbo charged power levels, but not bad.

 

You're absolutely right that there is no boost most of the time. However, my question is, is there no noise when there is no boost? The SC is still spinning even when it's not creating boost, and if the gears in the SC aren't helically cut, the unit still may whine like a crabby 2 year old...

I'm concerned about the daily driver issues with having a JRSC. The power increase it provides is beyond question, but what the weight and noise of the SC does to the car from a "living with it" standpoint is another question.

When everything outside is quite, and the motor is idling, you CAN hear a slight whine from the blower, though it comes off as more of some other rotating engine part rather than a supercharger whine.

Everyone is correct, the blower whine only comes into play when you mash the accelerator. During cruising the car sounds as quite as stock (well, mine was stock when it got supercharged, and it sounded like stock after it got supercharged!).

Here are some videos regarding the sound of the blower:

If they don't work, its cuz I'm hosting these from my own computer, and it either may be off, its being restarted, or my internet connection has crapped out.

Also keep in mind that upon installation of the AEM intake, the supercharger whine has changed dramatically. One of these days i'll take another video clip and post it.

Excellent! Thanks SO MUCH for posting the videos. You're right about the noise-- it sounds quite "livable" for cruising around town, but when the gas it hit, what a great whine! Assuming that your car and the other SC'ed Preludes keep their engines in one piece, I may have to get a type SH and JRSC it! It would look great next to my wife's '99 Prelude SS.

Does the extra weight up front cause any noticeable handling differences? Also, how do you like your adjustable Koni struts? Thanks!

 

How much does the JRSC weigh?

 

I doubt that the whole supercharger assembly contributes more than 50 net pounds to the front. Believe me, the power it supplies it more than enough to offset it.

Btw, the koni's were pretty helpful--setting them a tad stiffer in the rear canceled out most of the torque steer! You'd be hard-pressed to find a cheaper, yet more effective shock absorber (that's not custom, either).

 

225 is with ECU problems they were having.

 

There's a groupbuy for the JR superchargers. Prelude SH is listed at $2800 w/ FP and BTC. Also shipping is only $25.

$2800 is NOT bad. Any of you guys gonna get it?

I'm curious...... assuming a Prelude is equipped with the JRSC, what kind of cars would one be able to beat/smoke/keep up with, etc that normally would be out of our reach??

just curious.

iranman - any conquests to tell us about?????

 

Ohhh nooo, you weren't thinking of smoking someone on the freeway on the way to a Prelude meet, were you? Wait for the rest of us.......$2800 is a great price, anyone want to trade a JRSC with a drag turbo?

 

Nope...sorry...no major conquests yet (aside from the usual civics/integras/VW's).

I revved teh engine alongside an older man in an NSX, but he just waved at me, in an attempt to calm my desire to force him to eat my dust. A shame, too, as I was really itching to go up against an exotic car.

We should be able to handle S2K's and Older M3's (the new ones are waaaay out of our league now!). Stock-Mild Turbo Eclipses may fall into this category too, but it's all speculation. Personally I really don't care, I love my car, I love the way it handles, I love the instant power, and I absolutely adore the sound!
