How will this new cam affect my exhaust note/sound? hey all, i am ordering a Comp Cam 218/224 .527/.534 114 LSA tomorrow adn was wondering a few things. one, will it make my exhaust louder, deeper, etc? (mods in sig) two, with the mods i hav currently, what power guestimated do u think is realistic (dyno numbers with all current mods are also in sig) i know it is a rather tame and mild cam, but i like the low lift and the streetability of the 114. thanks!

What lobes does that cam use Clay? With fast ramp rates it shouldn't add too much of a lope at all really. You shouldn't even notice it too much. With your M6 I'd at least get it on a 112 unless you just really dont want any lope. With that cam and tuning I'd expect about 375rwhp/370rwtq as a safe guess (I dont know how that lower lift will effect things).

XE lobes and those specs, I think you should come right around those numbers. I still think you should go for more lift though. At least LS6 cam lift territory. If I were you I'd basically run a Z06 cam on steroids. Keep the same lift and use LS6 valvesprings, and bump duration up to what you're looking at right now. Something like...
218/224 .551/.551 114 LSA
...or around that neighborhood. LS6 springs will take that lift all day long for well over one hundred thousand miles, thats what they are designed for (LS6 cam is .551 lift). The lower lift will work, but the slightly higher lift wont hurt anything by a long shot, and it will be beneficial for you.
EDIT: This is just theory on my end. I'd obviously call up someone from Comp as they can figure in the valve events and exactly what would work best. Maybe those lift numbers you've got are the best for your combo. Regardless, I think that cam should have EXCELLENT low end as well as good response, so it'll be a blast to drive on the street, and should pick up significantly over the stocker.
