When you buy cams, you are going to want to make sure they are the best for your setup. If your case, you need to find cams that work well with forced induction.

Well, the best cams for forced induction are usually stock cams...

i'd agree since that which nitrous you still have the same amount of air coming in.

so turbo cams on a turbo set up dont work as good as stock?

no, turbo cams on a turbo set up will work better than stock cams on a turbo setup, however stock cams work very well on turbo set ups up til around 400whpish so cam upgrade for boost isnt necessary until u are at that point

And if you really wanna get into it, big n/a cams can actually help drop dynamic compression in the big lobes, helping to keep you avoid detonation a little more.

Re: Cams + Nos = bad???? You tell me! (LudeyKrus)
Sorry to hijack the thread, but are there any cams that work well with a supercharger? Or would I just use turbo cams? What sort of duration and lift would I need?

That is totally false
. There are 700HP plus b seriers on stock cams. I know of prelude in VA thats my buddy Jason tuned and made 534whp with stock cams. I can get my hands on crower turbo cams fairly cheep but Jason Hunt says its a waste of money, plus few other big names say use the money else where. Just my 2cents

Re: (hOndafienD 04)
From the book "Maximum Boost"
"Make no mistake in the fact that turbo performance cams are very different from atmospheric performance cams. The characteristics of long duration and high overlap for atmo cams are unwelcome in a turbo system. The street turbo, which is generally small, operates with 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 cam"
You do not want overlap with a boosted engine because the of exhaust gas reversion, and most NA cams have a decent amount of overlap...

ummm.....not on a turbo motor dude, those fat *** lobes will leak all your boost out during overlap....good turbo cams are little weenies!

Re: answer is what..... (Lude_Behavior_97)
It turned into a boost cams discussion because you would use the same type of cams for a nitrous application as you would for a turboed car since you're pushing more air into the engine in both cases

no you arent......nitrous makes gasoline more volatile....no more air than usual is in there......
boy some of the stuff people say.....

Re: Cams + Nos = bad???? You tell me! (jdmcivicferio)
A LOT of misinformation being thrown around in this thread.
Turbos and other FI options want more lift which cams can give. However, at the same time they want a reduction in overlap to prevent blowby. That being said the Skunk2 stage 2 cams CAN work very well for turbo's with their relatively low duration times. If you need less overlap you can tune that out with cam gears.
Nitrous can be very tricky with cams due to the fact that you're introducing a turbulent flow into the air stream by injecting nitrous/fuel into the intake stream. But generally you treat it like you would a N/A project. Scavenging effects are virtually the same it's more the tuning that you have to watch out for on these.
