200 206 grind question?

[JAM]

About how much hp is to be gained in going with the 200/206 grind with everything stock except a cat-back exhaust?

[Arctc Wolf]

how much lift, and how much lobe separation?

[JAM]

Yup, its a fair cam, I don't like the IC, and whats worse is I designed that cam (only with a different IC) and proposed ordering one from them a few months back. Same lobes, same lift, everything... really annoying!

Anyways, its a fair cam, it is mild and will have a good lope but nothing insane, and it will pull much further than 5500RPM. It is mild though, so if you want to be SES free and just get more power, its not a bad option.

I'd personally rather go with the grandprix store 206/212 113LS 110IC grind over that cam though.

[JAM]

So what type of gains should I expect, and how does that compare to the grand prix cam you suggested?

Does the SeS trip off any other codes, or is just an idiot light?

[Arctc Wolf]

oh, that cam. too small for my liking. bigger duration, about .500" lift, and i guess i'm a moderate w/ lobe separation, 113 or so.

SES = just an idiot light. [img]graemlins/thumbsup.gif[/img]

My experience goes to show bigger is not always better.

I think that cam would run very well on a virtually stock car. The only thing I don't like about it is the exhaust lift, I'd kinda like to see it at .498 also. But Dominic knows a little more about cam design than I do.

I dont see why anybody would put in such a mild cam. Everyone puts in a cam for more power. And there is alot more power to be gained with a larger cam. That is way mild not even pushing the limits of emissions or drivability so I dont see any reason why somebody would pick that cam over something a little larger.

I have had both a 3.8 with a mild and wild cam and the wild cam was alot more fun and far more powerfull. IF your going to do a cam do it right the first time and dont go so small.

[JAM]

Ok so if this is mild how much HP gains should be expected?

How does that compare to other cams that you fellas are talking about are more "wild"?

I agree pgrifith... doing it right means doing it that way the first time. Is why I ask lots of questions, and check with manufacturers etc. Looking forward to see what recomendations are made here. ;)

212/218 intake/exhaust duration 112 LSA 500/500 Lift

Would this be a pretty wild cam for a 3.4?

Would somebody please help me and JAM out? I'm also looking into getting a cam and was contemplating the 200/206 COMP cam. I have a SLP CAI and Flowmaster American Thunder Catback. I plan on getting headers before my cam. Any suggestions? Please help guys, Dominic, anyone....

There are a lot of reasons as to why your cam was ultra mild and this one is not if its done right. I wont go into those [img]smile.gif[/img]

Slacker and MalloyNX both have good size cams, check theirs out.

Well ANYTHING is better than the stock cam. Where it gets picky choosy is when you must decide what you intend to do with the cam. For just installing it as-is into what you have, you'd likely gain 30rwhp or so with the 200/206, of course here I'm just guessing. Comp did design this cam and claims its good so who am I to dispute it [img]smile.gif[/img]

Here are things I've found tend to be good in a cam, of course some of these I've yet to test.
1. 206 to 216 intake duration
2. 212 to 220 exhaust duration
3. Lift values below 0.500" if possible, 0.45" optimal on stock heads for n/a power.
4. a few degrees of retard ground into the cam (larger IC than LS by a few degrees)
5. LS's in the 112/113 range, ICs in the 114-117 range.

Your call is as good as mine, try something. Keep in mind Im going against the flow with my IC technique, but we'll see who ends up making the most power cam against cam once I order mine [img]smile.gif[/img] You'll hate me for it but I'm not releasing specs on the cam I designed until I pop it in and try it [img]graemlins/evilgrin.gif[/img]

Oh, and for those of you getting that 200/206 grind... Be sure to opt for an IC of 113, not 108 [img]graemlins/evilgrin.gif[/img]
