TR224 ok for turbo???
TR224 ok for turbo??? I was curious if you guys think that the current cam that I have is ok for a turbo setup. I have the TR224 which stats are 224 Dur / .563 lift 112LSA. I am building a motor for boost and want to know if I need to get a new cam or stick with the one that I got now. Thanks. 
Re: TR224 ok for turbo??? i have a 224/224-114 .561 and it does well
that 112 lsa seems a little low, which may bleed boost off.
if i had it to do over / my next cam will probably be a 227/223-115 .580

Re: TR224 ok for turbo??? My current cam
228/224 .537/.534 112LSA on 112ICL
It's not too bad, a bit peaky. You definately know when your starting to come up on the cam I haven't had a chance to play with advancing/retarding the cam, it's in straight up right now.

Re: TR224 ok for turbo??? I got the cam in my sig to be a decent N/A cam while i waited for a good turbo kit and then as well be a decent (slightly aggressive) turbo cam.
I am sure i will hurt my spool up a little.. but was hoping with some of the bleeding off during torque peak would help make for safer tuning due to a little less cylinder pressure then... and hopefully a little more HP up top, though i am beginning to think i made a bad choice.

Re: TR224 ok for turbo??? Your cam looks alot better than mine from what I have heard so far. I think Im just gonna go with a new cam for the turbo motor.
Probably something like this: 228/224 duration, .588"/.581", 114lsa

Re: TR224 ok for turbo??? bleed off boost, you should, still make the same amount of boost due to your waste gate config, but will be loosing effiency of the boost (but not positive on that)
Reason Harlan choose a 112 lsa was for mid cylinder pressure release for his high high horse power application....right Matt?

Re: TR224 ok for turbo??? When I bought my cam H/C from a friend who won it from ARE they sent me a cam that they said was great for a turbo. It was 224/224 .581/.581 114+4 LSA and had the specs:
--------open------close--valve timing at 0.050
intake--2 btdc---42 abdc
exhaus--50 bbdc--6 atdc
I ended up selling it and going with the Lingenfelter cam that they run on their twin turbo vettes (GT2-3). The guy I sold it to was supposed to be runnning a turbotech, and bought it because he liked the specs. I think he was looking at exhaust close relative to the intake open, which I read as eight degrees of overlap. Is that right?
