I've ridden in a twin motor tesla Cobra conversion, and trust me, NOTHING could beat it in the quarter. It's scary fast. If I could find a good NSX shell, I'd try it. Prices on totaled NSX (and most other desirable sports cars) are ridiculously high right now. So gonna have to wait until the...

Wow, first time back on this forum since I sold the car! Not sure why you decided to go turbo. That motor was a beast, finally got it sorted (no more dropped sleeves) and had over 550 supercharged RW HP and so much torque from the very bottom to top. Here's a link to the last tuning...

Nice project, good work. Remember, a good intake manifold needs to produce more than just good WFO dyno numbers. In most cases, it's throttle response that gets you around the track the quickest. Your plenum looks to be quite large and all that volume might create some driveability issues...

I used over 70 data points collected from July to Dec 2015 to create this chart. Miles on the X axis, dollars and the Y axis and the bands indicate various "condition and service" ratings. The vertical red line was for an early model with 50K miles. The data included 91 through 94 year model...

Congratulations! Please be advised you are well on your way to owning a $100k NSX worth about a third of that. I know, I did it. By the time you are done you could own a Ferrari. I know, I did that too.

Foothill blvd is quite a backtrack for me being in Corona. Can I hook up somewhere around the 138/15? Still doing dyno testing on the NSX so I'll need to bring the F Car. I just might do the whole route. Looks like I cant make guys. Have fun and drive safe.

I run ANSYS v15 and use the Fluent component for CFD. Moving mesh is fairly common now.

I running adjustable cam pulleys but with stock timing. DAL Motorsports suggested advancing both Int and Exh (more overlap) but that's for another day. I'm running 50/50 with a 300cc injector before the intake manifold just to be safe on 91. You can read tons of opinions on pre vs post...

see this link for dyno run. https://www.youtube.com/watch?v=KkqJyHCpItQ

Actually, I have two throttle bodies, one before the blower and one before the intake manifold (more or less the stock position). They are coordinated by the cable you're seeing and work one-to-one. When incorporating a large intercooler and associated plumbing the volume between the blower...

The twin turbo is still in CAD at the moment. When we get a customer wanting that system I'll build it. If I didn't feel there was 600whp potential in my current blower system I'd probably do it on my car. And yes, that's the new car, thanks.

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...

Do a search on the Real Time Racing (RTR) NSX, as I recall they used a similar supercharger.

Has anybody intentionally (or not) advanced the intake cam(s) one tooth (about 16 crank degrees) without interference issues? Thanks, Mark.

I have a facebook account but don't post much. I remember seeing a movie called "Sell Hard" where one of the principles (Will Ferrell) made a derogatory (but funny) comment about adults over the age of 35 posting on FB basically telling them to "get a life". On a side note, that was a GREAT...

Looks like we'll be free for awhile. We'll bring potato chips. Mark and JoAnne.

Keep this in mind. Percentage wise, the biggest change is going from 250 to say 350 hp (with corresponding TQ change). That's 40% and you'll REALLY feel it. Going from 350 to 450 is only 28%, yea you'll feel it, but not like 40% and it'll cost 2-3 times more. Going from 450 to 550 is only...

If I can get on the dyno at Autowave I'll stay for the meeting. Mark.

Same here Les. I'm scheduling another dyno pull next week after my latest mods. When all is said and done I'll be disappointed if it doesn't make 600rwhp. Mark.

I'm at Autowave today so I guess I'll stop by. Haven't been to a meeting in years. Mark.

If you like a high pitched Ferrari like sound go for a GruppeM exhaust.
