Supercharged 3sgte~3sgze??

Postby Overtriped » Sat Feb 02, 2013 4:57 pm

I've got a connection that has a whipple* s/c 2300cc capable of 30 PSI what do you think ?!?! Has anyone done this? [Image

Where on earth would you mount it?

the whipple superchargers are made for mounting on the top of a V-block engine, so I can't see any feasible way to use it on an inline-4. If you have your heart set on supercharging, check out the Rotrex supercharger used on a Beams 3S-GE: http://www.mr2.com/forums/beams-owners-group/Toyota-MR2-33226-supercharger-109.html He basically doubled the base N/A horsepower using a centrifugal supercharger.

typically they get mounted on the top near the intake, mine will have an IC so that has to fit in there too...I have a spare hood that I could modify. Keep In mind these supercharges are common and is reasonably priced used. Why wouldn't it boost if its hooked up via belt to the crank? I feel it's just a matter of building the right manifold and brackets...

I'm sure you could make it work, but why would you want a supercharger instead of a turbo? Especially on a motor that comes turbocharged?

More power for my dollar, I feel it's a cool alternative, less lag is good too.

It'd sure be different, but unless you just get parts for free I can't imagine it'd be more cost effective to remove a decent turbo system (even if it's just a starting point) and install a supercharger. If anything it'd be a wash money wise. Especially if you're looking to do ~30psi. That's expensive no matter what you do.

Properly built and tuned turbo systems don't have lag issues.

Could be cool though, just not something that would really make sense IMO.

so again, where would something that big fit? On top of the valve cover?

Yeah, basically. Pretty sure the hood would have to be cut- ill make it fit. The stock intake manifold would be replaced with a welded aluminum one. I haven't measured it but this build hasn't started yet, we will also be supercharging a 2jz aswell in the future. Another project that's In the works now is a twin charged Camry Image

In this situation it does seem plausible to twincharge. I do want to have an IC. We could make the intake piping work since I'll be going that direction on the outlet from the blower anyway.
