looking at throwing a turbo on my truck, and was wondering if there is such a thing as a mean sounding cam that can be ran with or without boost, and will be an improvement over the stock cam.

The triple 12 can be tuned to have a little lope and seems to be good n/a. Ill be running one eventually. Also, I think some guys are running the TU1 with turbo.

You'll hate life with that combo and a turbo. Well, that is if you want to win races. lol

Smokeshow are you referring to having to build boost again after you shift due to having a manual trans? MunsonAuto is running a 6.0L with an LS6 cam and turbo with a manual, and he loves it...

Thats a 6.0 vs a 4.8 lol

alright, point taken lol. 5Speed, only one way to find out. I'm sure that you'd still be able to find some fun in a turbo'd manual 4.8, might not be ideal but I'm sure it'd be fun. I was going to just throw a ls6 cam in my 4.8 but the low to mid end that everyone was talking about with the isky 12 (the lope of this cam too) made me fork out the cash for the isky 12. There's a member on here doing a twin turbo 4.8 with a triple 12 (project is called winter projects in the project thread) and here is an idle clip from him twin turbo 4.8, isky triple 12 cam, 550rpm idle - YouTube. got some lope to it. Hopefully I'll have mine installed in a few weeks here. Just waiting on my springs to come in.

I'm with smokeshow on this. A blower will be much better for manual trans than turbo. Instant boost instead of waiting on the turbo to spool.

As for a cam. U have a few choices that will sound and perform good. The isky triple 12 is a proven cam. I myself am using the Vinci turbo cam 216/216 114 Lsa and I just did a cam swap on my lil brothers 4.8 using a comp 212/218 114 Lsa it sounds very good and made a big difference in power
