Re: New (old?) Idea.
i've been trying to get my hands on a junk internally lubricated centrifugal supercharger headunit for months

http://www.subaru-svx.net/forum/showthread.php?t=36097 Google says it's a Legacy built by JC Sports, and it's not around anymore. I still need to get my hands on a supercharger and an intercooler to see if it'll fit in the SVX engine like it does in that picture of the Legacy.

Re: New (old?) Idea.
I don't think the intercooler part would fit in the SVX engine bay.

Plus you wouldn't have a good excuse to put on a hood scoop.

Re: New (old?) Idea.
I was thinking you might be able to make an air-to-water IC like one of these fit along the pipe on the side.
and the carbon fiber hood sitting in my garage already has a hood scoop, no excuse needed.

Ha nice. Where'd you get a CF hood with a hoodscoop for our car?

Nate picked up a parts car that had it on it. It's in rough shape (as is the car it's going on) so it will end up body color though.

Re: New (old?) Idea.
Do you really need an intercooler?. How much boost are you going to use and for how long, till you lift your foot?
The rest of the time the supercharger will be cooled by the air flow, and the amount of metal makes a good heat sink, for when on boost. Harvey.

It depends on what the car is used for, if it will have boost for long periods, then an inter-cooler is needed, as in circuit racing or diesels, boats, etc. I have run a PD blower on 14psi on the road, with the usual boosted runs, no inter-cooler, just water injection. Harvey.

Re: New (old?) Idea.
Yea, I'm running water-meth injection on my supercharger for cooling.

Also, I noticed that the site you linked says their intercoolers usually get 0.05 psi drops, but the specific one you linked has a 1.1 psi drop. What kind of supercharger setup are you running? I have yet to see anyone on here running a M62/M90 on the side of the engine like the examples linked earlier in the thread, and I want to know if it'll fit.

Re: New (old?) Idea.
I have one of LANs kits with the AX1600 between the block and manifold in the center. Setup at 12 psi with a built forged motor and custom ground cams and head work. Nismo 740cc injectors, new style subaru coilpacks. Still getting the tuning setup on the Hydra so I haven't had a chance to drive it yet, but man do I want to. Also has a 6MT/R180 and almost every bushing replaced. And Fortune 500 coilovers going into it when it warms up out. It was busy this past fall with all the work. Got things back together just in time to pull it into the garage for the winter heh.

Re: New (old?) Idea.
TireIron, that sounds like a BEAST!
Also guys, FWIW, I bought a Ford supercoupe M90. It's a LOT smaller externally, so it should be easier to mount/fabricate flanges for. Getting back on topic, a couple of extranious theories: My next idea: Make a crossover pipe between the plenums with the IRIS valve in tact. The problem I can see with this is that the extended length, due to the distance between the plenums, would interfere with the timing. However, could I tune the length to a second or third harmonic? This is strictly for the resonant system. From what I've read I understand it thusly: The stock system at low RPM uses an inertia system. This is the same as most other "Tuned" intake system whereby the runner length and diameter are tuned so that the inertia of the air flowing into the cylinder is at it's greatest. Too big and you don't build inertia, too small and it's restrictive, much like exhaust header tuning. The interia system I can duplicate by carefully designing my custom intake. That's simple enough. The resonance system however is more complicated, because it works on sound waves for the pressure pulses. This is the system that the IRIS valve was designed and tuned for. And which may or may not be able to be replicated. Am I on topic here or completely off my rocker? (Also, I'm still trying to figure out why they need a small port beside the IRIS valve, and then open the valve for a big port. Unless I've got my systems mixed, and the resonance (sound) tuning is for lower-RPM, while the inertia tuning is for high-rpm) |

Re: New (old?) Idea.
basically, it starts with a long runner intake for torque development, and switches to short runner intake for power development.
it's basically an IMRC, but with a single valve in the middle. in theory 2 properly designed intakes with the proper runner length should make the same peak horsepower, at the same rpm as the stock manifold. it will just get there much differently. but thats only if plenum size and length and shape are the same as stock. if you left the intake stock, but just removed the iris valve, so it was stuck in long runner mode permanantly low end torque would be the same, but it would seriously lack top end power. maybe producing 170-180hp |
