    564 whp supercharged

    After 6 years I finally got my car running again. This time the results were 564whp on 91 pump gas using an Eaton TVS 1900 supercharger with intercooling as measured on a dynapack dyno. There's probably another 30-40 hiding behind a slipping S/C belt and undersized (stock DC sport) headers...

    Giken LSD, good or bad?

    I recently procured a Ginken LSD (stock ring) from one of the usual NSX speedshop suspects. However, I've been told that Ginken is redesigning the entire unit. I've read that the Ginken can be a bit noisy unless very thick gear lube is used but if you can live with noise it's otherwise a good...

    Twin Turbo, inside engine compartment

    Here's a concept for twin turbos housed inside the engine bay. The design requires a fabricated intake with integrated Laminova core plenum. Core design shown is good for over 800 RWHP as are the turbos. Engine bay and glass are modeled in to check for interference.

    New Procharger, old idea with a twist

    Folks, I'm finally back to designing a new forced induction system. I'm looking for a new challenge so that eliminates turbos as it's been shown that these can make huge power gains despite poor design and engineering execution. No slam, but with a big enough turbo the sky's the limit (at...

    Control Arms

    Just checking to see if there's a demand for aftermarket upper and lower "A arms". I see quite a few posts looking for these pieces and I know they are rare (if straight) and expensive. I can reverse engineer the stock parts and fabricate them in chrome moly or machine out of billet alum...

    If you need a good technician . . . .

    Hi Phoenix NSX'ers. I've recently retired from Boeing in LA and moved out here to Gold Canyon. Now I've got time and could use a few extra bucks, so if you need work done on your NSX give me a call and let's talk. I can do the work or simply assist you with technical instruction while...

    Piston cooling

    I’m tying to figure out had to add full time piston squirters to my block. In theory, it looks pretty easy. Just drill a small galley from the main bearing webs directly into the main bearings oil supply groove, just like a Porsche. The two end webs would handle the front and rear cylinders...

    Low boost S/Cer interest

    With Comptech out of the S/Cer business I've been re-thinking my decision not to market a S/Cer kit. If there was enough interest in a relatively low cost ($5k or less) low boost (5 lbs) Eaton based system I might consider it. The layout would be based on my current design without the IC and...

    Caution to potential buyers

    For anyone looking at buying a used NSX you'd be well advised to check out the parts catalogs shown on this site and look at the prices of some of the typical maintenance items as well as some of the usual suspects associated with high mileage cars. Most will be shocked! I'd say any price you...

    Gruppe M S/Cer

    Guys, Do you think a supercharger (or any FI system) adds value? I added my GM kit to my project track car in the marketplace and everyone who's responded says it decreases (or adds no) value to the typical NSX buyer.

    Project Track Car JH4NA1159NT001106

    Why spend $25K for a complete NSX just to strip it down, add a cage, put wide fenders and tires and track it? Don't make the mistake I did. Putting a bunch of money into a street car to track it can reduce resale value significantly, a double whammy! if you're serious about tracking/racing a...
