Ok, now that the JRSC secret is out, I got a question that maybe someone can help with. On normal operation, at WOT, my guage reads 8 PSI, and it hits that level really early in the RPM spectrum. The ECU is automatically set to engage VTEC at 1PSI, to allow the increased flow. However, lately, the usual dull whining sound has become a little louder and weird sounding. It kinda has started to sound a little like a dying power steering pump. Also, the boosting is erradically jumping between 6 and 8 PSI, and it won't even touch 8 PSI until like 3500-4000 RPMS. Finally, the VTEC, which normally engages at around 2500 RPMs, isn't engaging until around 3200. Any ideas? Low end response and torque are taking a noooose dive because of this.

Leak or bad s/c

wow since ive been gone we actually started posting in the right sections, lol

im not sure, but 2500-3200 is low for vtec to engage. must be standalone and/or chipped ?

normally hits vtec around 2500? thats not normal..actually, thats far from normal...what engine are you running? b16?

in preludes (h22), vtec doesnt hit until 5200rpms, and then redlines at 7500...

just wanna see what makes your engine open up for vtec at such a low rpm....

so during daily driving, driving very easy and shifting early, your car falls in and out of vtec? dont think so....even when i shift my car very early, i turn it to 2800-3k rpms....just seems that to hit VTEc without WOT would fudge something up..

Nonono, you misunderstand me. It engages VTEC at exactly 1 PSI of boost. It's a Hondata computer. I am saying that at WOT, it catches the boost and engages VTEC at around 2500. Without boost, I usually leave it at 4600. The stock ODBII ECU sets it at 5400. Actually, your vtec engaging early without WOT wouldn't do anything but screw your gas mileage up and make it run sloppy. Alot of dumbasses buy a VAFC and tune it to engage vtec super low like it's some magic pixie dust that makes cars go fast. All it does is ruin your low end respose. Anyway, I personally think it's losing castor oil from the blower. I'm gonna go on a mission to track down any leaks today. I hope to god it isn't, because according to Jackson Racing, the only way to refill it and fix it is to give it to them and have them totally rebuild it, and that will be a pain in the ass. Not only do I have to completely remove the system, but I have to put back all of my N/A shit.

Goddamnit, this thing is running like shit. I don't wanna take it off and leave it N/A, it'll lose a shitload of power, but I might have no choice if I can't get it working right.

take some pics. ill buy it if u dont want too much. id like to see pics anyways to see how one would look under my hood.

Hell, I can show you where to see all kinds of different cars with one. You can't even see it unless you know it's there It simply replaces your TB and Intake manifold, and the pulley is down and hidden by the head. All that's there to give it away is that the TB tilts towards the front and is a little longer, and it says Jackson Racing on the top of the IM.

Problem is, if it IS leaking oil from the casing, it's ruined, and you'll have no use whatsoever for it.

we all know what a JRSC looks like on a honda engine, but we still want a picture of yours....so post it...

Lemme get a USB cable that will fit this stupid Sony Cybershot, and sure thing. I bought a regular USB cable, and it was apparently too big for the port on the camera.

Alas, I did find some drippage underneath the housing. Not 100% sure it's fron the SC, but I think it might be. I'm going to take it to someone who's a little more knowledgeable about these sorts of things and get their opinion.

ill rebuild it no prob. shoot me a price.

Hrm... I'll make you a deal. If it is in fact gonna have to be pulled. Along with that turbo, do you have the oil and vacuum lines?

I'd like to take a shot at rebuilding a sc too :)

you have to buy those for your specific application. advance auto / ace hardware has pretty much everything as far as those.

I think I could part with it in exchange for the turbo, assuming the turbo infact DOES have minimal shaft play, and is in good condition. Also, it has to fit my header. I got a guy who's going to take a look at it Monday at 2 PM, so we'll see what happens.

look in my gallery.... pics are under Brad's turbo talon and stuff folder bc those turbos have been in his garage at least a year now in a pillow case locked in a metal cabinet lol. one of them had shaft play the other one was fine. one is from a Daytona turbo the other is from another turbo Chrysler.

superchargers are for sissies :dunno:

I like superchargers
