I know the Comptech supercharger with the 6 PSI pulley typically runs around $5K shipped from what I have seen. And obviously a custom turbo kit would probably run slightly more, and of course there are a lot more factors that go into a turbo. And a lot more that can go wrong. But I just really want to feel like I definitely invested my money in the right place. After driving in my brother's boosted 7 PSI little RSX-S, part of me wants to feel our top end with a turbo.

All and all what do you guys think is ultimately the best way to go? I want to beat his car with whatever I do!

 

Well if your goal is to beat his car we'd need to know how much power his car makes. Since 7psi on an RSX-S doesn't mean much. Turbo, S/C, K-Pro? Exhaust?.....

If you want the most power go turbo. And there is a kit for sale right now in the black market for under $7k. Includes everything you need.

 

ThinJim's kit in the Black Market has everything you need - including all gauges and tuning. That's the kit to get. It still has the highest documented WHP that I know of.

 

Turbo has way more potential put it that way. If your happy with the SC max power and dont want turbo lag and want some more low end torque, then you'll be happy with the supercharger. Although with teh turbo kit it includes the IC so you'll have more useable power for a longer period of time then with the SC since more then likely you wil start to heat up the IA charge more proportional to how hard you run it. Plus you'll actualy have a functional blow off valve with the turbo kit

Although by comparison you can get the SC kit for about a third of the price if you do it right.

 

This is pretty much the main reason I think I would lean towards the supercharger, because of the price difference. But I just want to know what kind of numbers the 6 PSI pulley puts down, with intake/XS headers/pulleys, etc. In other words is it possible to ever break into 12's with slicks / DR's? I know traction is a major issue, but I don't want to feel like it was a ton of money spent, and not THAT great of result.

 

Well it depends if you tune the setup with some sort of piggyback you should see some good results. You can probably get 330whp just from the standard pully alone if you did it right.

Sean the first 7th gen SCed is running 4.5psi max on his J32A3 setup and he managed to get 329/280 at the hubs using the Greddy Emanage Ultimate and hasn't even touched the ignition tables or the rev limit remover. Thats why im questioning going with the HBP because I think the 3" pulley might be enough.

Depending how my fiscal situation is, I might sell the kit im building now for myself down the road, by then it shouold have the GEU, a tune, and everything needed to complete the kit.

 

I'm for the turbo... https://acurazine.com/forums/car-parts-sale-361/sold-fs-turbo-kit-2003-cl-6-speed-363786/

 

That dyno is being very generous. I haven't seen many 6-speed CL's break the 300whp mark with the 3.5-4psi pulley. Typically with the 5.5-7psi pulley you'll hit 330+whp.

This of course is with only the FPR and the ESM. But I don't think the EManage is helping all that much with the exception of a few points on the curve.

 

You would blow the doors of a S/C'ed RSX with that kit. It would not even be remotely close.
