For a 4.8 with a 96mm 1.32 ar t6 cam would be 230/230 .600/.600 113.5+3 lsa heads could be either 317s or 862. I am sure 862s would spool faster w the higher compression. Hot side would be 2-1/8 inch piping

Have you looked at foose04 s475 gen 3 4.8 truck? granted its 4600lbs but its a nasty setup. Is s475 is a billet wheel race cover but he is moving alot more weight.


is the 4.8 your using a gen 3 or 4?

We just finished a buddy's car in January with a 4.8. Similar to what your asking about. It's got a 228/230 112 cam arp studs and ls9 gaskets with a cast s480 1.10/83 t6 with a 2 1/4 Hotside. It made like 680 or 690 on 18lbs through a th400 and 9in. He had a gt45 on it b4 and the s480 spools a little slower but not much.

IMO that cam is much too large for a turbocharged 4.8.

It will have a harder time spooling.

Most of the 4.8 turbo cams I do have 212-218 degrees intake duration.

The cam I already have, the 4.8 I have, the 1.32 ar s475 I have on the way already. Friday after my 3rd pass I melted a piston and my choices if fixing are a set of 8:1 dished wiseco pistons for the 6.0 that I already have or a 4.8 that I already have. Im running pump gas and meth will be added when running again. Almost feel it will spool the same no matter what way I go.

If i didnt already have the cam, id cam it accordingly. But this is why I had to ask, needed some input from everyone who has done these two together.

Yeah ive read his setup, he has the small t4 83mm 1.10 housing so it would spool a lot faster.

My setup so far is 02 4.8 with 243 heads 227/231 623/598 114+5 LSA and a S475 T6/96mm 1.32 backside!

Again this is what I already have, worse comes to worse i'll spray the damn thing!

Awesome i cant wait to hear how it runs and does, its definity gonna be a beast when spools up

Hopefully, looking to make 700-750 thru a th400!

I got a full floater rotating assembly ready to go if the current motor pops!

Let's keep the topic on point please. Fact is things change over the years, and what worked last year, may have been improved upon.
Now move on with the discussion.

Well looks like my 6.0 that torched the piston torched the cylinder wall as well. So its on to working with this 4.8. With the huge the 1.32 housing.

Lol. You have a way of putting things nicely

Well, we're all adults here right? So if you guys act like mature adults I will extend the same courtesy and act accordingly.

What do you mean "chokes"?

I just like to see people with a nice finished project, not something that is the product of someone learning how to do their job on customer vehicles. Happens all too often, particularly in the automotive aftermarket. Very unfortunate.

Compressor choke. It is determined by the isentropic efficiency of the compressor dropping low enough that it cannot flow any more air. Increased heat output lowers air density so power making capability reaches an asymptote, or choke point. A turbo will almost always make more power on a smaller displacement engine.

Turbo runs out of air.
