I am not really against the JRSC, I just believe that the install is too tight, and the car and engine just doesn't lend itself to an SC install.

I am also biased because of all of the bad stories I have heard from JRSC owners (not hearsay). I have heard from plenty of ITR owners that the JRSC doesn't live up to JR's power claims, and I have heard from many Civic and Integra owners about engine issues (idle quality, etc. etc.).

Look at the JRSC install pictures. The brake lines must be bent in order to make room for the belt drive system. The PS line runs over the valve cover (which means you have to remove it to do a valve adjustment). Since the PS fitting won't fit properly, JR puts this ghetto adapter on it. They should have machined a new PS fluid line instead of using an adapter. The prototype SC had a much better setup for the PS line. I hope you don't have any injector problems with the SC installed. It looks like you would have to remove the blower to get to the injectors. It also looks like you would have to remove the belt system to get the valve cover off. Geez, doing a valve adjustment looks like it will be a *****!!!

The blower design is also very good on the JRSC, however it lacks an intercooler (or aftercooler, whatever you want to call it), so intake temps will get very high at full boost.

I question reliability of the SC and of the engine with an SC installed (with no internal upgrades). I don't have anything to say about it, I just wonder how things will turn out. The belt system is my main concern.

Oh, and it's not the price that turns me off of the JRSC. I could buy 2 JRSC's for the price that I am paying to get some good output NA.

Thanks Billy, for sharing your observations
about JRSC. I've been waiting for JRSC
for last 3 years (I had it in mind when
I bought the car) and I am about to make
decision on it. Right now I'm leaning
toward "let's do it" side.

You pointed out some of the questions that
I want to sort
out before I fax out my credit card numbers.
I hope someone can answer or comment on it:
aircooler.

I am thinking about designing my own cooling
system before the induction occurs. Somewhere
between the filter and the SC. I have three
options.
1. pipe over so that the cooling device
sits on front grill (i can probably buy
parts from turbo-part orders)

2. carve out a hole on hood so that
cooler will be exposed to outside atop
of the hood

3. use active cooling system (using a/c
compressor already in place); my ac will then
be on all the time. does anyone know ins
and outs of this approach?

If I were to go with JRSC, I want to have
a plan at hand how to cool the air. I concur
with Billy that temperatur has everything
to do with SC and engine reliabilities.

KC

PS- btw, how are you guys (do it for your-self types) comming along with SC installment if you bought a kit?

Uhhh, have you put much thought into this? An intercooler, like those used on turbos, can only cool air as cold as the ambient air. In other words, running the air through an intercooler BEFORE the SC compressor will do absolutely nothing. It doesn't matter where you mount it, with a hood scoop, or in the bumper. If it is plumbed in before the compressor, it won't cool a damn thing. And no, it's not possible to plumb one in after the compressor on the JRSC.

Use the A/C?? How do you plan to plumb that? Also, how are exactly do you plan to implement this? Where would you put all of the components? Again, it will go before the compressor, so the effect at most will be minimal because you won't be able to chill the incoming air significatly below ambient (unless it's damn hot outside).

I think that you need to do more research into what's fesible.

Billy, I don't have a plan at hand.
Just random thoughts.

Dang you are right. No way to do intercooler
on JRSC since it mounts right on the
throttle.

I think I can pull the AC idea off though.
I can put heat exchanger right on the JRSC
it self.. cooling down the casing it self
in hope of cooling whatever is going on
inside. All you have to do is some freon
tubing and this is not expensive at all.
If I am very unlucky, the temperature
gradient will crack the SC chamber and i'll
be one unlucky dude.

Hmm.. I am guessing
doing all this is still hella cheaper than
spending 2xJRSC as you aspire for NA.

Good luck. I will stick with my NA work.

kckckc:

Good luck using the A/C cooling system. If anything, you'll end up robbing power due to the A/C compressor and will more than likely screw up the system. Keep in mind, your A/C system can only cool air by about 20 degrees, and the volume of air is no match for the massive amount of heat that's transfered from the hot cylinder head to the supercharger. JR makes a water injection kit which provides an intercooling effect, but it's not really worth the investment and added complexity if you ask me.

Want a power adder? Strap on a well-planned N2O setup.
