You don't an intake manifold for a supercharger depending on how you mount it. I don't think the RIPP kit used a custom intake manifold, it simply ran piping from the supercharger to the TB. I'm sorry, but you're not going to gain anywhere near 50whp-90whp for 2000$. I would guess a custom kit would be 4000$+ and would yield maybe 40 whp, maybe.

 

Ya most superchargers are not cheap either, unless prices cam down since the last time I checked a few years back

 

This is all ballpark and speculation figures man...by your estimates, nothing worth it.

 

Yea I rather get a turbo!

 

Yeh I knw, u think im stupid? I think I would rather fo supercharger route than turbo route, but until I get the cash I can think about it

 

This is not irony, but it's pretty damn funny nonetheless...

 

I loled at it.

 

You're spelling doesn't help any.

Anyone going the supercharger route? Going custom?

 

Spelling bugs happen :S

 

proof reading goes a long way....

 

I contacted an Australian shop about superchargers. They have done a lot of work on the previous generations. He first said he hadn't really thought about it, and I emailed him a pic of the engine...then he replied by saying this:

"It could be possible, not sure what cost the turbos are but I could prolly arrange a SC for around $5.5k and the power delivery would suit the engine much better than the turbo, its just how the MIVEC is that makes it more suited."



Kindest regards

Then, I said, well...$5.5k will be steep for applications in the states, and then he said:

"I think it would be in the high 4k range and pressure would be 10psi, that’s pretty much the standard pressure we do for everyone."

It might be a pain in the *** to import a kit though...would have to be a great kit.

 

On the stock engine 10psi is way too much unless u want it to go boom. If we had a CR of about 9:1 that would be just about perfect(thats if the alluminum block can handle it, though Im sure it could) What type of superchargers do they usually work with? There is also another good company based out of Australia that specializes in Mitsu- RPW that has retailers in the USA if you are worried about importing a kit, last time I checked they made supercharger kits in the past

 

We didn't get into technical specifics about compression ratios. I know for example, from my experience from the Tiburon world, that 10psi was attainable on their aluminum block, and they did it. I just love all the speculators that say this can't be done blah lah, it was exactly the same when the '03 Tiburon came out. They said it was gonna explode at 5psi...weak design, all that. Now look at it, the supercharger kits from NextGen are amazing.

 

Like I said before I do believe this block can take that kind of PSI the weak point is still the CR of 10:1 is still too high to run 10psi of boost safely and running good, think about it why do you think the Evo X is running a CR of 9:1 sure it might be running more boost than 10 psi, but still try to find any other car that is NOT direct injected that is running a CR of 10:1 and 10psi or higher of boost, you probably won't find many if any(that is running damn near perfect)

 

My guess is to run 10 PSI you'll need to consider replacing the pistons and the rods and maybe doing some headwork to take full advantage of the extra air. The 4G94 has a compression ratio of 9.5:1 and it ran into problems at the 10-12 PSI range (completely stock of course). It's all a matter of what you want, if you just want a fast car for a little while, boost the hell out of it and when it starts to die, sell it. If you want a reliable car equal to a factory equipped turboed/supercharged car, you have to expect to pay.
