E-cam vs B-cam? - Page 4

The cam is not a part that will give 25 more HP. It will
give from 12 to 20 Hp more. Then when you swap the B
(+12 Hp*** over stock) to an E (+16 Hp*** over stock) you wont
see a huge difference but why choosing the worse when
both are at the same price?

***Per the MM&FF dyno session

I totaly agree that the cam could cause idle problem. However
when the car dies all the time and the idle is always surging
every time the engine is around 900 RPM. It is too easy to say
that the cam is responsible. When the problems are major
it can t be the cam alone....

Is that a fact? Is that why the only way I could cure my car of a surging idle was to swap out the cam?

A cam can and will cause idle problems, mainly in fuel injected (computer controlled) low vacuum, narrow lsa applications, like the e-cam.

I don't think the LSA is the only culprit on the idle problem, but it's certainly a contributing factor. The E303 isn't real great at making idle vacuum, which is a common problem for a cam with an LSA of 110. I think the problem is compounded by the LCA being uneven. exgmguy found creating a vacuum leak solved his idle woe's, which makes me think the offset LCA may be causing a somewhat inconsistant vacuum reading at idle, which would play with the computer.

Hey, something we agree on.

Also, I don't think 500rwhp or 600 crank hp with a supercharged 302 is anything to sneeze at. The rest of the combo might have made 350hp for Dan or Nic. Supercharger boost was about 9psi, non-intercooled. So they were picking up 250hp from 9psi. That's a serious gain.

9 psi on top of 350 hp should make around 600 hp, however, I dont believe your average e-cammed, 9psi blown car is making anywhere near 600 hp. Sorry, just aint happening.
