212/218 c.c. versus tr224? I am currently running the Comp. cam 212/218(in sig) which runs very well
but I am trying to get into the 11's and wpould lik3 to know how much do you guys think the tr224 would increase hp/torque over the 212/218??? btw
dyno info in sig. which I thought is a little low but vets run that way
. Or is there a better selection that wo'nt shake much?

My buddy Mike (posts here as Jaberwaki) his ws6 if im not mistaken put down somewhere in the 390 rwhp ballpark with his 224 through a cut out. i have a 224/228 on a 114 lsa and i dropped down 372 untuned. very streetable cam too. i was at 33X rwhp (dont have the dyno sheets infront of me right now) before the cam too.
so with that said, i think over the 212/218 cam you'd probably see a solid 25-35 rwhp difference, which i doubt by itself would get you into the 11's, but i wouldn't forsee just gears getting you into the 11's and staying there. to get there and stay there id suggest the 224 and gears. i would think that would get you into the 11's and keep you there.
Goodl uck man

tune it yourself?If I remember correctly increasing the duration on the ext. sidewas a little harder to tune but increased the top end?

I love small duration cams - they are highly under-rated. Yet to make them perform you either need a kick-*** combo to draw the torque OR run on a smaller LSA. 212/218 on a 114LSA is just too wide IMHO. The fact you are still climbing at 6200RPM tells me you could do with the TQ coming in earlier. Check the ICL and if theres room for advance move it a few degrees. Cheaper than re-camming and worth a shot before ditching the thing altogether.
A wide duration cam will own a small duration cam at high RPM. So my advise would be to rethink what that cam does best and maximise its potential before trying anything more costly.

212/218 I have that same cam(212/218)and I put down 339rwhp and 388rwtq. I love that cam in city driving. What was your peak rwtq on that cam? I'm curious, since not very many people use that small of a cam.

ADvance the cam? The torque was pretty flat peaking at 5000. How in the world did you get such a high torque number???restrictive exhaust???

ICL = Intake Centre Lobe angle
That is, then degree angle at which the intake starts to open.
If its like IVO 68* then you can advance it a few degrees to bring on the power earlier.

and the cam I am currently running has 4 degs. advance built in should the next cam have 5 or 6 degrees built in ??? Am I reading this correctly???

Ray, I don't think you are letting the car breathe. If you put an LS6 intake, a good set of LT headers and free flowing exhaust you could pick up anothe 35-40hp with that cam. I just did a h/c with the 224/228 .581"/.588" on 112lsa @+2 with AFR 205's. I also have Kooks and an LS6 intake. I put down 413rwhp and 396rwtq through 4:10's cats, and mufflers. The cats are Kooks hiflow and the mufflers are Corsa Indy's. I just did h/c and got +75hp over what I had before. Before h/c I did 337rwhp through the gears and boltons.
if you don't mind the hit in gas mileage,i would do the gears first.if your power is still climbing at 6200rpm,then with your 2.73 gears your probably going thru the traps way below your peak hp(i would guess around 5300rpm or so).i don't know if it will be enough to get you in the 11s but it will definately help.

I made a mistake earlier. When I said IVO I meant IVC, that is, Inlet valve Closing. IVC dictates the dynamic compression and hence if you advance the cam you increase dynamic compression by closing the valve earlier. Too much advance and you run into detonation. So in my previous example its the IVC that might have 68* ABDC. The IVO could have anything from 10* to 30* BTDC.
If you want power to come on earlier, and you have a cam with an IVC that permits a few extra degrees advance, then you can safely advance the cam to bring on the power and torque earlier. Cheaper than doing a cam swap, though not as thorough as the LSA will still be the same.
The earlier IVO the more dyamic

thus learning from this the next cam all else be relatively equal the same line of thought should apply????thanks for the info !!!

was trying to be a sleeper but I just installed the Corsa catback system
soooo sleeper is out of the question. 
Do you know if that Comp cam, 212/218 high lift, has any advance ground in to it?
How do you figure out the overlap from cam specs?
Thanks if you guys know (and sorry for butting in Rays C5)...
