I've been wondering about turbo cams for a while. Mine makes good power despite being an itty bitty .486" custom grind. I don't have the specs in my head but I have the cam card at home.
I know the turbo Buick guys as well as the Supras were running really strong numbers on stock cams.

i had talked to my brother about the motorcycle cams used on a turbo hayabusa making 600HP from 1400cc's and he said the cams are a lot like the N/A cams.

Still have this cam sitting on the shelf from my old roots setup solid flat tappet.
252 262 @ .050 .560 .580 lift 114 lsa I believe.
Turbo setup has a solid roller I'd have to look at the cam card again for exact specs but its about 274-286 @ .050 .680 .680 116.5 LSA. Idles like a .509 mopar cam.

The wide LSA is to keep overlap and reversion to a minimum, you want to use the boost to push the piston down, and not let the exhaust back into the chamber or intake charge. When LSA is narrower, overlap is larger. (all other numbers being equal)
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.
9.94 @ 134, 318 on pump gas, 14 lbs w/ Eddies, transbrake 727, 3600 lbs, 3.54 gear and 28's.

Here's my monster cam specs. Think you can hang with this baby? This is rocket science right here! intake/exhaust .006 duration 284/280 lift .474/.483 .050 intake open 6 btdc close 50 abdc .050 exhaust open 48 bbdc close 4 atdc duration at .050 236/232 lobe lift .3160/.3220 separation 112 You can see there's only 10 degrees of overlap. That's as tight as we could get it without going to a custom blank. Keep in mind that this cam was ground 10 years ago. Comp wasn't doing a lot of turbo cams since turbos V8s weren't very common. Much has changed since this thing was built. I'm sure people know far more about turbo cams now than they did then. However, this thing makes decent power. You can't argue with that.

After trying ALOT of cams and turbos on the same basic engine, I came up with some very basic self tested rules: The smaller the turbine, the smaller and wider you want the cam. Pump gas likes less lsa at higher boost levels. Race gas likes more lsa (seems backward doesn't it?) A free flowing turbine/wheel combo will like a cam closer to that of a n/a engine, don't be afraid of a 260+ cam.

A cam like that would really flatten out engine performance, unless you had HUGE turbine wheel(s) and housing(s). There is to much int/ex overlap to run a normal turbine selection. On the positive side, you wouldn't hurt your engine with a cam like that. You would contaminate the intake charge with alot of exhaust gas. You wouldn't make enough power to hurt anything.

You're the first one who's ever brought that up. All I know is that was as close as Comp could grind it without going to a custom blank. I wanted as little as possible. It's worked for several years so I guess I can't complain too much.

Yours is a roller which does change things but it's still a lot more cam than what I've got.

I'm thinking about a cam swap. Currently running a Paxton blower with a 216/220, 114 LSA. I have 2 other cams I could use. One a 219/224, 114 LSA and the other a 205/210, 116 LSA. Also have 4.56 gears and 3800 stall. The truck has always e.t'd better than MPH.

There is a defined range for rpm/ duration. You are operating above and beyond that range. Supercharging or turbocharging helps to stretch that range. It lets you "get away" with things that you can't with a N/A motor. In your case, you're "getting away" with alot. 5000+ lbs and almost in the tens,,,, you're doing good. Treat your engine to a little breathing. Go with at least 230 @050. You will be pleasantly suprised.
