What kind of specs would create a lopey sounding idle and still be efficient for a turbo. for a otherwise stock 4.8

How lopey? What size turbo, and converter? How much boost?

Well I got a 212-212 562 lift 112lsa +5 for my 4.8, should know in a few weeks how it will idle but I know its going to have some lope to it, anything with small dur. and a tighter lsa will work good for boost cause over lap aint a problem. Remeber you dont need a big cam to make big power the turbo will hold it back more then the cam will, a bigger better flowing turbo with and a smaller tight lsa cam will spool just as good as a small turbo with a big cam but make more torque when the boost comes in.

Enough to notice, Ive just rebuilt my 4l60e and put a vigalante 3200 in it. Im on 7lbs now with a mp70 but plan on turning it up to about 12 soon

My stock48 spec'ed isky 212 has a lil chop in my lq4. Gives it a nice lil noise at the red light.

I have a custom gring 218/222 on a 111lsa. It has a very nice chop. I dont know how good it will be for a turbo cam but I will find out.

Durations, lobe profile, lsa will make the chop.. You can get away with a tighter lsa turbo cam and still notice a decent difference

A 212/109 ~110 lsa Isky would chop and work pretty good in a 70mm 12psi 4.8L. The problem with high psi and tight lsa is it can detonate easier.

Geoff at EPS spec'd my cam. 226/222 on a 112+2 LSA. I can honestly say, it chops. I could pass mine off as a cammed NA motor with no problem.

Any sound clips? If i dont find anything I might just stick with a ls6 bump stick and keep it more sleeper-ish
