is there a difference in supercharging a base than an SH? i was on the JR site today and they've listed two chargers, one fo the base and one for the SH. the SH is $200 more. what gives?

 

The supercharger is setup a little differently on the SH due to the location of the atts. Thus it is a little more money.

 

Its also easier to install, can go without an intercooler, and much less efficient.

 

what can go without intercooling, the SC for the base or sh? you don't even need an intercooler for a supercharger anyway. are we even talkin about the same thing? i think you're comparing a turbo and a supercharger. that's not the original question. but thanks anyway.

 

Look man, you don't have to be a ****, he was just expanding on the explanation. He is correct though, you can use an intercooler on a Supercharger to make it more efficient.

 

No intercooler has been, and IMO will ever be, designed for the Jackson Racing Supercharger for the 5th Gen Preludes. Sure, intercoolers help out F/I setups, but you guys failed to look at the product here. Do some research before posting useless info. Have any of you known any JRSC-equipped Honda with an intercooler? And who said anything about it being less efficient?

The difference in price involves an oil relocation kit, and that's all. The rest of the kits are identical, and the same goes with almost all of the installation (exceptions being a few ATTS-related wire splicing, and one minor hose that's removed).

You could have also found this out by reading the instructions on JR's website: http://www.jacksonracing.com/media/m...df/989-650.pdf

Don't ask me why they marked it up so high, though.

your intercooler is NOS!
and intercooling is one major reason that nobody likes supercharging.....(JRSC)
who like hot air being forced in your cylinders....that air just gets hotter the longer you have your car on as well

He said that an SC with a intercooler is more efficient than one without an intercooler. That's correct. I haven't seen one on a JRSC, but it wouldn't be very hard to weld an air-to-water intercooler. You'd have to relocate the battery to the trunk to make room for it and to balance out the added weight.

 

Yeah, what he said!

I see domestics with intercooler all the time! So, just since you haven't seen one on a Honda, do say it can't be done!

Useless info my ***!

 

Chill out presidente, I was just trying to help. As I would hope everyone knows, a supercharger is supplied with its own power, where a turbocharger is MUCH more efficient and uses power that would otherwise be wasted.

 

It would be very difficult and would require a total redesign of the JR supplied hardware for mounting. There have been many attempts to make an IC for the other JRSC Honda kits without success and they have alot more room to work with than the H22a kit.

You see intercooled SC domestics all the time because they have space for mounting of the SC away from the engine that allows all the piping to be run and also allows room for a lazy-boy and a small tv. Also many of these are using centrifigul superchargers like the Vortech which is alot easier to run IC piping with.

 

I agree that it would be a pain in the *** to mount an IC between the JRSC and the block. I was proposing to, theoretically, build an IC, so as to cool the intake charge before it arrived at the JRSC. And like I stated earlier, you would have to move some things out of the engine bay, such as the battery, to accomadate the IC.

 

From experience!!! IC on JRSC did not do so well, thus they came out with water cooled injection which DOES make one hell of a difference. I dont think that JR has come out with a true "IC" for there units yet!!

 

How would you cool the intake charge? The intake charge is already ambient. To cool it any further you would need to use icewater or some other way to condition the air to below ambient. You might be able to set something up for short runs, but it wouldn't be a daily driver type of intercooling without constant ice water it would just be a restriction in your intake.

Someone on Hostboard experimented with routing his A/C into the SC. It didn't go very far, but it was an interesting experiment. I wish had had done dyno runs.

 

Water cooled injection works through the SC itself.

 

I was thinking of a liquid-to-air intercooler. Since when are any of the messed up ideas that I get compatible with daily driving?

 

Ha!

#1lude, I was actually replying to laighin2.2's post. You got in there one minute earlier than me with your reply, so my reply looks all screwed up. I was talking about an air-to-water intercooler, not water injection and actually water injection is sprayed after the supercharger, not through it. Spraying water through an eatons blower is a good way to burn it out.

JR is the only company that refers to water injection as an intercooler and they do it only as a marketing ploy.

 

If I'm not mistaken, there is a port on the blower itself, that I believe, JR has included as a port for their WI nozzles. I haven't researched this, but I do know of a port on my blower.

Also, for what it's worth, I've seen/heard of many Water Injection installs where the nozzle was placed before the throttle body. Has the wearing away of the coating on the rotors been substantiated yet, or is it still hearsay?

 

Most water injection kits are made as universal install kits, so they install before the throttle body on the intake pipe.

There was someone on Hostboard maybe 2 years ago that installed a Spearco water injection kit before the supercharger and showed wear on the rotor blades.

 

i'm chilled out. didn't mean any harm by that thread, my bad. anyway, the reason i'm going SC instead of the turbo is maintenance issues. a turbocharger requires much more tedious maintenance than a supercharger. according to what i've researched, you can run on stock internals with a JRSC where it is recommended to change the pistons and rods with a turbocharger. and it also affects the ultimate reliability of the car. this is what my friends with turbos tell me. also, my car is my daily driver so i would assumed that a supercharger would be better for a daily driver, whereas a turbo would be best for racing. i dont' race my car that often. tell me if i'm wrong, i'm goin by what i've been told and what i've read.

also, where can i get more information about all this water cooling and that you guys are talkin about. thanks

 

I agree with you one that one. If I could do it all over again, I would have gone SC. But I am head over heels into the Darkside, so good luck in what ever you do. I didn't want to seem like a dick before, but it sounded like you didn't even appreciate the info you were receiving.

 

I'm sorry, but that information isn't entirely correct. Let's take a look at each of them:

- Maintenance. Both supercharged and turbocharged require equal amounts of attention if properly installed and tuned. Read over that last line, it's important. Both require extra attention to the engine fluids, and overall condition (i.e. shorter intervals between major tune-ups). You skimp out on these and you deserve to have a blown motor. With the Preludes, I'd have to say that the JRSC requires more effort for the same maintenance, due to the larger components sitting in an already-cramped area of the engine bay. Check the website in my sig, and look through the pictures in the Multimedia section. Do your research.

- You can run stock internals on any F/I setup under 9psi, generally speaking, as long as the motor's TUNED PROPERLY. You can ruin stock parts on a JRSC setup just as equally as with a turbo setup. Period. If you need to upgrade/replace these parts at these low boost levels, then the tuning's obviously off. Either the ignition timing is too advanced, the motor isn't receiving the fuel it deserves, or (most probably) a combination of both.
You'll hear of turbo guys rebuilding their engines (forged low comp pistons, rods, sleeves, etc), only because they desire to increase boost levels to a point where they stock components won't take it. Once again, tuning becomes even more crucial here. (Are you beginning to feel a common motif here?)

- Once again, both work equally well for a street, daily-driven vehicle. It's up to you to decide which one suits your needs, and we can't answer that for you. Similarly, both work well for racing, and the same above rules apply here as well.

Pretty much do a search on your favorite search engine(s) on "Aquamist."
