Default Idle Speeds for 112LSA Cams on M6 Cars

What seems to be the average idle speed for medium sized (around 224/224) cams on a 112LSA in an M6 with bolt-ons? I know all cars are different, but what RPM is most common?

Thanks,
Josh

I have mine set at 950 (A/C off) and 1050 (A/C on) but my cam is a bit bigger. I would think 900 would be about right for your size.

I have a T1 cam from MTI and have tuned it to idle at 800. The key to a good idle on my car was giving it more timing.

Thanks for all the responses, guys, they're much appreciated.

Hey man, how's it going?

Yes, I'm planning on doing a cam next. I've not completely decided which one to go with yet, but it's definitely next on my list.

When did you get yours? I'd love to meet up with you sometime soon to have a listen to that thing.

Take Care,
Josh

I have my TR224/224 112LSA idle at 850RPM (AC off) and 950 (AC on). I "did" have it as low as 650 at one time but in hot weather it was too fussy at lights.

Had it set at 700 when I was cam only and never had a problem. Since I put heads on the car I bumped it up to 800 and she can be a little tempermental at times. Hot starts she will hunt for 3-5 secs and if just pute around a parking lot and push clutch in she will die some times.

My T1 idles at 800 with the A/C off, not sure with it on. It sounds damn good at 700 though, I may lower it.
