Turbo camshafts
 

Do you need to be running turbo cams if your going to boost? Easy question, but I dont know the answer.

Re: Turbo camshafts
 

Yes, because we all know that your Non-Turbo motor won't even start without some Turbo cams in it if you put a turbo on the car!!!











But seriously, No you don't. Having them will open up your durations allowing the excessive air to flow into the cubustion chamber better, and flow out better. Giving you a altogether better turbo motor.

lmao....um no :S

"Turbo" camshafts are just low duration, high lift units. This type of profile helps prevent reversion of the exhaust back into the head due to the turbo created backpressure. This is a good idea to use on a motor that creates a lot of low end torque mated to a quick spooling turbo setup. However, with most of the motors used by many of our list memebers, they don't really get into the power until the middle to upper rpms. Reversion won't really play that huge of a role in this aspect, since the motor's VE is characteristily low in this range.

This is just a general rule. But if you feel like you need to run a "turbo" cam, then try one out. Or better yet, ask a person that has run a stock cam and a turbo cam, to see what their impressions are on both.

Mild NA cams work well, too. Or really really hot NA cams. LS + Crower 404 + boost = teh win!

The Gospel according to Corky Bell:

"Make no mistake in the fact that the turbo performance cams are very different from atmospheric performance cams. The characteristics of long duration and high overlap for atmo cams are unwelcome in the turbo system. The street turbo, which is generally small, operates on exhaust manifold pressure somewhat higher than intake boost pressure. This situation, when presented with long-duration, high-overlap cams, creates a huge amount of reversion. Thus the "turbo cam" tends to become a low duration, very limited overlap camshaft.."

RULE: It is hard to find a turbo cam that works better than the stock item.

Re: Turbo camshafts
 

So in other words better just to go with some Crower's or somethign like it other than turbo cams.

Re: Turbo camshafts
 

best to just stick with the stockers and up the boost
