Correct. There is an s464 & s466 as well as different combos on the turbine side.
Lets see some videos of that thing!

3800-4000 range. If you dont have upgraded valve springs & more fuel its kinda pointless to go over 3400 IMO.

I have a bone stock CP3 with 134,000 miles and 40% nozzles.

im hung up on the s472, im just wondering if i should stick with a smaller s366 or a larger than stock vgt turbo because of emissions.

Other than the cool factor, going bigger is pointless isn't it? Build the bottom end so you can use a huge charger..

So at what point is the decision made to build the bottom end other than by it blowing up, anything over stock? I understand it needs to be done.. but, there are some people running alot more charger than stock on stock internals, yes, it's way more risky but there has to be a more defining point to say this turbo will work and this turbo is pushing it and there is no way in hell with this turbo, etc... I just don't want to spend the money on a 4094 if it's not a good choice and I don't want to buy one that's gonna grenade my motor.. so what do y'all suggest?

DMAXchris where did you get yours from? I was looking at Danvilles website

Directly from Bullseye Power through my local diesel hotrod shop. Danville is a Bullseye dealer so they can take care of anything you want.

No video but heres a crappy pic of my current setup:



billet 366, currently running stock LBZ CP3 with 40% injectors. I just added profab manifolds and it really helped the turbo spool up. my cruising boost is down a few rpm over my batmo stocker. drive pressure is right at 1:1, egts at cruise are at 7-800, slightly lower than stock(that was before the manifolds).

I suggest getting the VVT off of the motor if you're after performance. The sooner you do that, the happier the truck will be. Take Ryan Funks' truck for example. He's almost in the 10s on a stock motor with big fuel and an s475. He's probably somewhere in the 750-800 rwhp range. I believe its due to fact he's been running a non vvt charger for a long time. The better the charger flows on the exhaust side, the less stress there is on the bottom end.

Ohh and an s464 is enough to blow head gaskets, I know from experience lol..I don't have the truck back yet, should be done this week and going to get it this weekend hopefully!! I will have my wife take some videos or something.

So would you say I'd be good doing a s475 (or smaller?) on a stock cp3 with say like 40% overs with only head studs? Basically, I'm new to the specs on all these different chargers and not sure what is good for what and what exactly I need (exhaust flow,etc., etc.)

The set-up on your truck is pretty much my main goal... minus the expensive goodies inside.. for now

Please excuse my dumbass commentary.

"all right, here we go, gettin' on the highway, going to roll into it like normal"
Just so I'm clear, 45lbs of boost and 80mph is "rolling into it like normal"?
hahaha, truck sounds good bro.
