    • Gintani Stage II supercharged E46 M3 (S54) at 10 psi vs. 390 whp LS2 Corvette

      An LS2 corvette is a very, very capable car. Quick in stock form and this example is modified with headers, intake, full exhaust, and putting down 390 whp on a Mustang dyno. The E46 M3 is running a Gintani Stage II SC at 10 psi with meth, it puts down 485 whp. It is making almost 100 whp more than the Vette, but we are a bit surprised is pulls so easily right away. This really wasn't much of a race and shows how strong the E46 M3 can be when boosted.

        Yep, exactly.

        I understand that.

        This is where I get confused: I didn't have a "liquid cooled" Kenne Bell blower. I could have upgraded for one--would have only cost a little more than a grand. So, I had a non-liquid cooled blower. I still had the heat exchanger and I still had the IC core. I asked KB several times and they told me more than once that unless I was running higher than about 12psi (I wasn't even close to that) I wouldn't see the gains from the liquid cooling.

        I'm not a dick at all dude, just ask anyone who knows me. I just didn't like seeing all the BS about Gintani/OE posted on M3forum. So I decided to put up some valid examples.

        As far as the kit goes, We chose to run the Si trim instead of the T trim, being that the T-trim really isn't necessary. Dyno proved that the Si trim was making slightly more power at a much sooner rpm then the T-trim on the same application. Also note that my car is only running CSL headers and we are still building a full exhaust for it, which should yield some extra power as well.

        My goal with this kit is 500rwhp on race gas + meth once the exhaust is built, on Gintani's Dyno Dynamics. Which as I understand, is somewhere in the 550rwhp area on a DynoJet.
        I can probably get near that number as the car sits with just running race gas but I want the car to sound a little better as well.

        Nobody likes seeing that stuff but if you are expecting to be able to provide examples and actually be able to provide your perspective m3forum is the wrong venue.

        Why not? You mean for stock internals?

        He is saying that the Si trim is more efficient at the impeller speed they are running (10psi). Once you start raising the boost and getting out of the efficiency window, the T trim will be a better choice.

        Gotcha and yes, that is correct.

        I'm going to have to pick a blower soon... Click here to enlarge

        Very exciting. What are you going with? I love the sound of the V1. Straight cut gears. Mmmmm...

        The v7 look mighty nice under my hood. Click here to enlarge

        I'll be going to Mfest. I hope to run some VF, AA, HPF (stage 1 & 2), ESS (e46 and e9x) cars, and some E60 M5/6's, or whatever else.

        Good to see you're putting it to use. Enjoy in good health bro.
