^^ wow! I wanna do something like that to my car.. wonder what'd be the budget for the project

 

^^^This sounds like $40K+.
This thing should drive like a GT3 and sound awesome. Any youtube?

 

Jmccarty, very very nice list of parts. Also those numbers are great considering you live in Singapore where the humidity is insanely high.

I looked through your gallery and have a few questions. For your wheel torque, I think you meant to put down 329.7/1.25 = 263.76. You have some plots that you compare your current number to, is that your stock car or another stock one? Also, did you guys run the test with that HKS race gas?

 

Pictures?

 

^check his user gallery.

 

just did .. Looks legit

 

Gabe - We did use racing fuel, HKS & VP113, both perform the same with my car. The temperature and humidity were atrocious at time of dyno testing.

263lbft is correct at the wheels, my mistake.

It's the cooler season now in Singapore and the engine is run-in with about 20,000km on it. Might be worth another dyno run!

 

What duration/lift cams?

 

ramirj2 - It is louder than the Porsche Carrera Cup GT3 cars that raced here during the F1 2009. Of course, those boxer engines have a very diferent and unique sound of their own. Tunnel runs scare the %*it out of unsuspecting others when you drop it down into a lower gear at >5,000revs.

We have been meaning to get some youtube footage since the tune was completed. I'll suggest it again to a couple of friends and see what I can come up with before end of the month.

 

03threefiftyz - 264 degrees intake, 264 degrees exhaust, 10.5mm intake lift, 10.2mm exhaust lift. Intake valve timing is increased to 90 - 130 degrees (vs stock 90 - 125).

 

Compression? With 264's those are pretty high numbers.....granted its on a dynopack.

 

Sick build man, not something you see everyday. Now I want to see you and Adam's car go at it since we're bench racing. Bets anyone.. JK... LOL

03threefiftyz - Lester, the lead tuner at the HKS Technical Factory here in Singapore, says >12:1 though I can not verify that today. I'll see what I can do when I bring it in for servicing before end of week to verify it.

What dyno would you suggest I use to test against the dynapack? I'll ask around and try again.
