The best dyno chart I have for it is the 414 WHP chart if you want to see the curve. That was 20 psi. Later on we did 25 psi and my guesses put it at 450 WHP (well above 500 flywheel HP). Traction really started to be an issue at that point.

That is stock DET cams on a stock DET head. The entire block from valve cover to oil pan was stock. The cams were certainly not worrying us any.

Best shot of the setup I have for now.

the only reason i changed cams is the reason for the other engines failure was lack of lubrication which showed firstly in the no.3 lobe of the inlet cam, where it had spun on the rocker arm and worn both cam and rocker arm[/QUOTE]


You might want to look into the cam oil tubes they have issues clogging up and the holes are under sized for proper lubrication . They make revised ones .

Also start a build threas in members rides section i like following those especialy you crazy Boost junky aussies !

Apparently lack of oil to cams is a common issue with SR20's my engine builder recommended using mineral oil over synthetic to combat this better.

its also a common problem with the chev 6.0l V8's he now uses mineral oil in his and has not seen another issue.

Hey man, make sure you create a thread in the classified section to sell your stuff. We don't allow sales outside of the classified sections.
