When I talk to Gunnar I told him I wanted the highest cr I could go with 94 octane.he told me 62cc will yield me approx.11.1.That is how I based my decission.I hope I did not do anything wrong.Let me know If you think I did.
No, no. It's just that you're talking about static compression ratio, but dynamic compression is what matters. That's why you mill... to get a static compression ratio that is high enough to get the desired dynamic compression with the cam you choose. I don't really know how dropping 2cc's will get you that high in compression, and I don't know how the TR224 works out in dynamic compression on that setup. You'd have to find the thread on it and do the math. I just thought that 62cc is a really odd size.

Ok I am trying to figure my dcr.I have a few questions.Please if you don't know dont answer.Engine is 01 ls1 I need to know piston head volume(cc),gasket bore(in),deck clearence(in).Does anyone have the cam card for a TR224 112?I need to know the intake closing point(degrees) ABDC @.050.
Thanks
Thanks
PianoProdigy had a DCR calculator on here somewhere. That way you just plug in your cam grind numbers and the rest is already there. The TR224 is an XE lobe with +4 advance, I believe.

YankeeVert,How do you like that cam for a street cam?That Is the one that I am going to go with.Do you happen to know the intake closing point is on that cam.I just wanted to try this calculator myself.Its not that I don't believe you.How does setting this cam up on a 4* effect it?

So more aggressive than XE and a tad less than XE-R.
just an update.. Im the one that started this thread.I ordered the PRC's and Im very happy with them I made 411rwhp and 372rwtq N/A and 550rwhp and 538rwtq on a 150 shot and thats with a A4 with a 3800 converter and 4.10 gears..my tuner said that if it had been a M6 it would have been around 450-460 NA
hmmmm.. not to burst your bubble.. 411rwhp with your current set up? Although those are "decent" numbers for a stalled A4. I am running a G5X3, unported LS6's ( for now) full bolt on's, and a Vig3600 stall and put down 403/405 @ the wheels.
Like you i am looking @ ported heads and had the same question. I will be going with TEA's stage2 LS6's.. I'll post up the results once installed.
No disrespect intended... Your's are good numbers...TSP makes an awesome product..
