Can you tell a difference from that to 8.5:1? I'm going monday to measure the cc of my head and my pistons to try and come up with the correct gasket thickness for my CR. I was leaning towards the 8.5:1 though unless you know of a reason not too. Does the 8.9:1 give you more power without boost? I guess that's what it does, but is that why you do it? Just curious.

yes, the higher compression ratio does usually give you a little more power per boost, and faster spool/response. I had a really thick head gasket on my GE-T, only because I used some bad information. I lifted the HG on a dyno pull, so I figured it was as good a time as any to slap on a thinner HG. Differences between the two were minimal, but I did retard my timing quite a bit for safety.

Didn't realize you had swapped HGs. What RPMs do you see initial/full boost at now with the MP T70? Wonder how mine will feel with the stock 10:1 c/r :evil2: Can't wait till I get it inspected and break the clutch in so I can swap injectors and run high boost w/E85 :naughty:

That's gonna be awesome Josh. I usually see 25+ PSI by 4500 RPM's :).

Cams are in, I have a video of it at idle for later. I'll post it after I re-tune.

How much did the cams run ya, if you dont mind sharing?
it was around 700 I believe, it took a couple months to get them so it helped me repress the hit to my wallet

Much props the final product looks great
Thanks, it's not quite finished yet. I'm finally happy with the numbers, but the car needs quite a few things before I'll leave it be.

Tonight I finally re-painted my wheels to get rid of the horrible 'graphite' paint that was on them before. It literally sprayed out like grains of sand. I went with a silver coat which went on very smoothly, while the paint job is far from flawless it is MUCH better. Pics tomorrow hopefully :)
