Cam Timing with Supercharger
#291
Thread Starter
Well, I don't think I can answer that. There is more cylinder filling....more power. More blow by would depend on the rings. Strain on the motor...not a problem. Crank case pressure..?

After all my efforts getting my car back on the road and running good, I am leery of performing this operation though, as strait forward as it is. I dont like the idea of undoing the head bolts. hg failure scares me a bit running my pressure level and injecting water/meth.

This is my only worry about running these keys at 12-13psi. Has anyone been using these keys for a considerable mileage without headgasket failure?

I was wrong in my previous statement about unseating the head when removing cams, this tree is completely separate from the head bolts as I have since discovered after pulling the head. Just wanted to make that clarification. So in that sense there is no risk of potential HG failure when installing the keys. As far as increased cylinder pressures causing potential HG failure, that's a separate question.

Odd that on 9-5-2011 you had no NA experience, yet 4 months prior in your FS thread you claimed otherwise (on 5-7-2011):

The theoretical gains from these woodruff keys are interesting for sure. (Relative to my 2.4L NA 12:1 shortblock w/ stock AP1 head, kseries skunk2 ultra race IM with F-to-K CNC adapter plate, custom 3.5" intake, urge exhaust header, urge/gernpipe dual T1R exhaust). But I may just go with adjustable cam gears (Toda or skunk2) given that I'd get reuse from them if I ever did upgrade to aftermarket cams.

Yeah, nobody seemed to recreate the success one person had. I definitely wouldn't try to find which specific keys would work for my 2.4L setup. Would require way too much costly trial and error. Only way forward if I were to pursue this type of optimization is to switch to adjustable cam gears to reduce the time needed between testing adjustments on the dyno. But not something I'm prepared to get into at this point. Bigger fish to fry getting my car ready for this season (upgrading intake manifold, getting retune, installing spoon rigid collars, a full SBG BBK, etc) -- my first year of autocross. Don't need to sabotage myself getting bogged down with cam adjustments.
