I want a cam that has a terrible idel. I want it to lope so bad it sounds like it is going to die out. With this comes a real tight LSA. But at the same time i plan on spraying. When using the juice, you don't want as much overlap. If I go ahead and get like a 110 lsa on a custom grind, how much will that effect the nitrous? I am willing to sacrifice a little for the sound of the big lumpy cam. If a little juice goes to waste, oh well. Is there anyway i can have my cake and eat it too?

 

No.

I won't say that placing more emphasis on sound (when performance is your goal) is really stupid... but it might be.
Who is going to care what you car sounds like at idle when you get beat by a sprayed import?

 

very true...I know what i'm about to ask is really a what if situation because there are so many varibles to consider but "hypothetically" if my motor made 400 hp from the flywheel with a 114* LSA cam (i know too many factors to think about, duration, lift, ect...) and i sprayed 150 shot, that would yeild 550 hp. Now, if i swapped out that cam for the exact same cam only on a 110* LSA grind shouldn't it still make 550hp? Or does that amount of overlap really kill power when running forced induction or nitrous? Another thing to think about is by going to the 110* i could possibly pick up more power on the NA side but maybe loose a little while spraying. Overall power on the juice would stay the same.

 

Personally, I wouldn't worry to much about what Lsa the cam is ground on (for sound purposes). My cam is on a 114 and at idle, it's very choppey (even with a tune). Really surprised me how much of a lope it has. Also, you can have your idle lowered so it will chop a little bit more if you find out it's not enough for you. But I would suggest maybe getting something on a 112 if you can't make up your mind.

 

A freind of mine is using a nitrous specific off the shelp comp grind it has a wide split 230/242 with 114 lobe sep and wide lift split 510/540 w 1.5s. It sounds like a full blown drag car at idle, but is pretty mild mannered on the street (not great brake vacuume though).

 

what about the le2 cam? i know the specs are closely guarded but as far as sound

 

Sounds like you need to call up the person that's doing your head work, and have them match a cam to your heads with the characteristics you describe. If you don't have a 'budget' like you say, then spend the money and pay someone else to think for you. Seriously though, try my first idea.

 

As an amplification of what robvas proposed:

1) Use the cam that makes best power for your engine/nitrous.

2) Add a solenoid controlled vacuum leak to the intake manifold, and a PCM override that misfires a couple of cylinders. Connect this to a "bad idle" switch, so you can have the terrible idle you want when you are showing off. I'd suggest using the horn button for the idle override switch and a hidden toggle that changes the horn from horn to idle override.

No joke here. I pretty sure you could get the effect you want with some creative work. Might make a neat kit! Shoot, in the old days we'd just pull a plug wire or two and a vacuum hose when cruisin' McDonalds.

 

WOW, that is creative! I never thought of something like that, its really a neat thought! I would just say suck it up, and make power, and stop worrying how lopey it will be. Me, I wanna monster cam that idles like a stocker. I don't want to give away whats under the hood just by the way it sounds. Thats just my opinion though.

 

Leave it to an old-timer!
