dropgear

hey everyone,

if anyone has an installed Jackson Racing SC setup, please let me know. Specifically, i'm looking for a functional D16Y8 96-98 or 99-00 install.

I have to debug something, and I don't trust the work of the shop who helped me install it.. sigh.. I'd be willing to drive pretty much anywhere within 2 hours of Mississauga to figure this out.

If you could offer some detailed pictures of the area around the PVC valve, SC Gooseneck, Brake Hose, Purge Canister, etc. that'd be even more awesome!! Basically I'm looking to ensure that all the external valve and hose fittigns for the SC are hooked up properly.

Thanks
Dariusz

I know one guy on here use to have a JRSC. Was Silver-Bullet if I remember right.
Think it was just a normal SOHC though, not VTEC.

what exactly is wrong with it?

He wnats to make sure the hoses are hooked up right.

The problem is that I'm not making 8psi (closer to 4), even though I have the 8 lb kit. I've checked the following things:

- belts + pulleys, size and length and fitment all OK
- hose setup... there's really nothing attached to the super that can leak out boost, with the exception of the master brake cylinder (but I need that to stop, sooo I can't really detach it)
- fueling ... while the fuel supply is shady (FMU), it's fully functional. fuel pressure calculations yield a very rich mix..
- timing.. retarded 5* from stock, which is fine. set it to -10, and the driveability was much worse, so i set it back.
- exhaust: aftermarket 2"+ high flow all the way from valves to pipe...
- haven't thrown an ecu code for a while, and all electronics read "normal" values..
- oil change yielded 3.5L of oil, no white stuff, but i don't know how to check for "blow by" without taking the head off...

anyways. that's been the journey so far. i have a few ideas of what it could be (fueling, leaking PCV, improper EVAP/Vacuum hose setup, ****ed up supercharger), so i plan on tackling each one by one.

thanks to the guys who replied and offered their services!! any help is greatly appreciated.

maybe the charger is worn out. i had the housing fail and the stator, I sent it to Jackson, they re did everything then I was up to 12psi. 300 usd inc shipping

Altech did Slvr-Bullet's install so they should have some experience. Despite the fact that they are thieves.

Is there any disadvantages of supercharging? I heard the boost builds up or something of that nature which isn't good for your engine?

But it is belt driven so instant HP at the throttle right? Will a SC car reguire larger muffler or you can do your car up in NA form, then just put a SC kit on it?

The G2 Racer

I don't know of many disadvantages off S/C Charles (unless you have a beat up motor...KABOOM..hehehe). However they take power to make it, it's very minor however, nothing you'd physically feel.

S/C aren't instant, well Vortechs are do to their design, centfrical (sp?) vs. a roots. Roots blowers will give you boost almost instantly (03-04 Cobras have factory Roots blowers and you know how quick they are).

You really don't need a larger exhaust with any type of Forced Induction but you'll see better numbers with a larger exhaust system. Ultimately you could just have an electric cut out so when you want all the power, flip a switch and you got it.

yeah Charles you do it up in NA form and then SC it. anything good for NA will help SC too, but your cam profile would be diff't. also your exhaust should be bigger than NA so as to flow enough for the amount of pwr you are gonna make, but it should still provide back pressure. it's not like turbo cars where no exhaust is the best.

disadvantages are basically two:

it's an accessory like air con or power steering, meaning it takes power to drive it

it's limited by design in it's efficiency and also pulley size (meaning you can't have a variable pulley.... so the smallest pulley you can put on it is the one that won't overspeed the compressor at your rev limit.... therefore at lower RPM the compressor blades turn relatively slowly)

as a side note the most efficient supercharger is the centrifugal (basically a turbo intake housing mounted to a pulley) and the least is the roots blower. the JRSC is the twin screw type (eaton style)

dropgear

I think I'm going to have to explore that option. Does anyone do JRSC rebuilds in Canada? I don't really have the time/money/energy to have the super uninstalled and reinstalled, with a 3 week gap in between....

dropgear

Since no-one makes a D-series centrifugal blower kit, Jackson Racing becomes the best option.

Other disadvantage:

VERY limited intercooling space. At 12psi, the efficiency of any supercharger kit hits a ceiling unless you can intercool. In a SC setup that means one of these:
- water injection (sweet...)
- NOS as a cooling agent (hella sweet),
- water-to-air intercooling between the SC and the intake ports with a seperate water pump, top mount intercooler, hole-in-hood etc. (the 'proper' solution)

... so realistically, 10-12psi is the efficiency limit unless you're talking big money OR twin-charging.


Advantage:

- my experience is that total cost of ownership is lower than turbo
- responds well to fuel-pressure tuning
- less false information out there..... everyone seems to be a turbo expert. nobody with an SC, for example, will tell you that your car will explode without a blow-off-valve.

As for the exhaust question: I recommend 2.25" if you plan on running a legal exhaust.
