i love these threads!! FIGHT!!!!!!!!!!!!!!
j/k,
so i have a valid question for everyone. i have gsc272/264's for my 05, why do you only see GSC cams doing this combo, i don't see hks or comp doing this combo. is there a particular reason?
i went with 272/264's because i would like to autox my car and from my knowledge of reading this would be a great combo because i would no only get great hp numbers but great tq numbers too.
for all the people fighting back and fourth, correct me if i'm wrong.
264's straight across the board = great for the guy who is look for just a little extra pep, nothing special
272's straight across the board = superior everyday daily driver setup
280's straight across the board = the superior highway car setup and setup for the next big thing in turbo's
272/264 = great autox setup
correct me if i'm wrong boys... just trying to state some facts that i've pulled from all conversations about cams!!
either way, in the end, it's what you will think is best, not me or the next guy or TT, or BR, or AMS, or TTFP or the guy around the corner!! lol, ok, maybe i pushed that a little too far...

That is an expensive proposition for most people, so I'm thinking people just stick with what's known to work without being too adventurous.

Ted B,
When I said "wager" I meant that you would recommend the 272's over the 280's.
Now then, the guy above has made an interesting point on the 272/264 combo, as I've been told by some credible people like Evodave that 272/264 combo makes a lot of TQ over the 264/264 combo.
My question is, which profile will make the most TQ (presupposing HKS & BC are the same advertised lift & durration)in a car with my mods, straight 272's, 272/264, 280/272 or 280's w/cam gears?

What it does prove is that longer duration cams, when properly adjusted, allow one to increase midrange rpm VE (torque), but without sacrificing high rpm power. This results because the motor responds favorably to increased overlap in the midrange, but the longer duration cam delays the closing of the intake valve, which preserves (and improves) high rpm power.
Is this why mitsu has a longer duration on the intake cam stock? Also, then would it make sense to do a 280/272 combo to maximize midrange power and retain all the top end? Or would that combo basically be like putting on 280/280 w/ camgears? I bought a 280/272 combo, but there are hardly any guys out there running it.

Hey "Ted B",
Could you please answer my question, I would really appriciate it. I'm supposed to pic out my cams this week. I was wondering about a 280/272 with cam gears, could I get the best of both worlds , mid & upper RPMs w/out sacrificing low end? or should I just go w/ straight 272's? I would really like to squeeze as much torque & usable HP out of it as I can, I really want the car to pull hard up to RL @ 76-7700 rpms.

Sarge: The 280-272 combo is a best of both worlds setup IMO. AS previously mentioned, CBrown, as you probably know, got his highest trap speeds on the stock turbo with this combo, so they are big topend power adders. I can´t give you any dyno figures, however FWIW, my car with a TME 10.5 and 280-272´s set @ 2/0, hits 20.5 psi by 3100 rpm from a roll starting at 2500 rpm @ 5 psi.
Edit: Oh yeah, the idle is unique at 2/0. Spilunking idle. It has crapped out on me once or twice...always on a very steep hill(in front of mom´s house) shifting into 1st when pulling into her garage. But, it´s worth it as the idle alone scares off most ricers.
Edit(2): For Trinydex...the idle underwent a radical change when I went from -3,-3 to 2/0. The retarded timing had a lot smoother idle with just a few blips and burbles. Whereas, the advanced setting sounds plain gnarly....almost like a normally aspirated, carbureted, sohc 4 banger with a 326 degree race cam, and way big 48 DCOE Weber carburetors with the biggest venturis available. The -3,-3 setting just lacked that shove you back in the seat midrange punch, which the 2/0 setting has gobs of.

I just got 280's comps, and adjustable cam gears, fidanza. They fell great thru all gears, just higher up in the rpms. Idle is nice and lopey, but not even close to stalling, get a good tune with them and it will be no prob.
