I don't want to get too much into it because it isn't my car to do so...
But with 10:1 pistons and 272's, he was only able to get about 8-9* timing out of the 2.75 without meth. My old Cobalt with just 500 dollars into it ran better times. Needless to say, the car was slower than when he had the M62. These car like timing more than boost.

i never had a desire to try and play with a turbo cam vis cam gears in a blower car. it cost me less to swap cams than to get the gmpp cam gears.
plus, the valve cover gasket being 55 bucks a pop. it doesn't appeal to me to pull the cover every time, check the torque on the three bolts or to adjust them for different conditions.
im a simple person. simplistic things last longer

About that... I've had an idea to modify a spare cover I have laying around, to allow for quick adjustments on the dyno....
... with that said... I'm a experimental person.... I like to tinker...
Plus I figured, I've got the cams... I'd might as well run them for a while, until I figure where I'm going with the car.... then get a good set of full blower grinds done.

the cover has a habit of leaking after you pull it 5 times in a weekend. yes it is reusable. to a degree.
twzt. yepo. i knew about it when he pulled the cover.
omega. good luck with that one. flinging oil is amusing

... not with the car running... 
It would be a simple mod to allow the side to be pulled off between dyno runs, while car can be shut off.
It would not be a daily driver mod... but a cam tuning mod, only.

Seriously dude, every time i hear news about your car, be it good, bad, or just news... i want to drop my turbo setup and go HTV like no other.
On a serious note, you think i could see about 315+whp on a 2.75" on a 8.9:1 compression?

looking for some advice here seeing how this topic involves cams,... JBP sells cams for the 2.4 and within the next year or so im looking to go turbo... should i get these cams and will they set me up properly for boost, or should i get them then have them reground?
any help is help...

Yeah but my compression is a bit lower then yours. I know you made what 313whp without meth? Hows the blower run with a pulley smaller then a 2.75. I know you ran a 2.5 but i could run say a 2.6 or 2.65 and make about ~335whp? Or do you think I would see the same issues you speak of here as you have with the 2.5? I wonder if the added displacement might help a bit with the heat(less pressure)?
