Cam with turbo ???

[mike24]

I was wondering of the cams avalible which one if any would benefit a turbo setup? Also is it worth running a new cam with a turbo?

[Mighty Thor]

A cam and a turbo is not a good combination. Reason for that is because a cam will increase the compression ratio of your engine and a turbo, potent as it is, will detonate your engine. Kinda lame but I've heard of a guy who changed his cam on his Civic and put a Vortech and it didn't take long he detonated his engine.

If your heart is set on it then try Supersix's cam. They seem to be better because it doesn't raise your compression that much and you could run a medium boost safely.

there are cams DESIGNED for use with a turbo, thats what I recomment you get.

Let just put it this way unless you are running over a 1 bar of boost a "turbo cam" is really not necessary...now if you can find someone who can precisely customize one for you (which I haven't seen yet) then go for it...but I know for sure you will be wasting mula...the technical aspect is a bit complicated because it really depends on so much factors especially what power level you are looking for...

what do you mean by "precisely customize"? If you tell Tom from SuperSix what you plan on running (ie:boost), he'll design it to fit the application

comp cams will also make a cam for whatever you need custom specs.

The word "boost" does not necessarily mean anything when it comes down to understanding the physical characteristics of an engine especially when a turbo is added. Uncharted territory, powerband is wayyyy different and "turbo cam" needs to be profiled properly. Reread the post, no single info was giving on whatever "turbo setup" he wants besides the bumpsticks...so I'll restate without getting too technical a "turbo cam" strictly speaking...is not worth it for low boost believe it or not, but you will gain more (assuming we are still talking low boost) from valvetrain mods like porting and polishing etc!! Too many variables to consider and I am assuming it is for a 3800 which already has a narrow margin of tunability due to the factory PCM...now if you were going all out, then it will be safe to say an aftermarket PCM will be used, then I will welcome the idea of messing around with the bumpsticks!!

Thats some of the worst advice i've heard, ever. PCM programming would be my only concern.

First off, turbo cams are easy to come by, and crane or comp will be able to help him out no sweat. To say that anything under 14psi won't help is just wrong wrong wrong. Cams don't change your CR. With increased duration of the cam there will be more air in the chamber which will put increased strain on the pistons, but he'll need to push less boost for the same horsepower, which means a reduced risk of detonation.

There's too many factors to get into here, if you want knoledgeable advice call crane or go to turbobuick.com or something.

v6turbo,
I was only stating the facts, mike24 did not provide any other info regarding his setup, besides this is one of those" hey I want to run only 5-7 lb of boost, do I have to go run out and get a forged bottom end" questions...do as you please, but believe me when it comes down to force induction on the 3800 II, I stand my ground and as you stated it is so many variables to go by especially with the small amount of info given...and do not misunderstand me, yes there are gains but how different is the cam profile for a 3800 NA and a custom cam (turbo)? depending on what you want but in principle you want more lift, a lil duration and watch the overlap...now numerically what numbers can you plug in? Well doesn't it depending on the characteristics of the engine, the turbo and then the owner...now ask yourself how much will a "turbo cam" cost remembering its going to be custom...?
We just did a dyno for one of our 3800 II turbo with a t3 and this thing put down 295 hp at 4800 RPMs with only 6 psi of NON_INTERCOOLED boost. Bone stock L36...everything besides an aftermarket PCM and a turbo with whatever accessories that supplement it, tell me won't you be satisfied knowing that with just less than $100.00 you can actually break into 300 hp? Maybe it's just me then...
