I have a Dinan intake on the M3 now. CSL intake may be inevitable.

Re: CSL Exhaust Valve Weight??

Class rules for SCCA GT2 are pretty open. Cams, valves, head work are all OK.

No CSL style intake.



Right now, a stock M3 head with Schrick 288/280 cams. The extra head I just picked up will be the one I have worked over.

Agree. There are lighter options for the intake valves as well, but not the drastic weight difference compared to the stock intake valves(47.5 grams), again about 5%, expected.

Some of the other...

Stash, yes the CSL exhaust valve is 5% lighter but the valve face design is the trick. As duly noted, the 30g weight on Real OEM seemed far fetched for a non-titanium valve. Now where to buy them. ...

Thank you. That's what I've been looking for. No worry on the stock valve weights, we have those from Stash.

Is the CSL valve in your photo coated?

The inaccuracy of the stock valves weights in Real OEM leads me to believe their weight of 35 grams for the...

Re: Camshaft Group-Buy -- Interest Thread

Stash weighed two very clean stock valves for me.

Intake: 47.5
Exhaust: 45.2


Not sure Real OEM is accurate.
