labor rate is near 70 hear but there is no way i will charge someone that. there comes a time where you have to be compative and still produce same or better work for less.

Thanks for all the info.
I talked to leadfoot diesel a local perf guy today he said he will do the entire labor part removal,tear down,rebuild, install for $4000
I think im going to do The removal my self i ist that much harder than a powerstroke is it?
1The engine machining no sure i know i want to cryo treat and balance the rotating assembely
2 At least deck the block to clean the sufrace! Heads?
3 Pistons i have been told will not last for a long time on the road unless You use factory or molly factory replacements (LB7).
4 the guy at industrial said 1 cp3 modded will be plenty for their VVT TURBO and 30% nozzels.
5 turbo industrial vvt or cheeta vvt?????? PRICE INDUSTRIAL $1400 NEW
6 headers???
7 trans is already paid for wating for converter ATS!!!
Can anyone tell me if the combo sounds good for reliable 800HP? And any other options im forgetting?

I think im going to do The removal my self i ist that much harder than a powerstroke is it? no its not.1-2 hours 2 guys can have that engine on the ground in front of the truck.
1The engine machining no sure i know i want to cryo treat and balance the rotating assembelydont have to do the cryo. def balance it ;)
2 At least deck the block to clean the sufrace! Heads?unless they are warped/out of spec i would leave them stock.
3 Pistons i have been told will not last for a long time on the road unless You use factory or molly factory replacements (LB7).iirc there are several guys runnin fordge pistons with no exccesive were on the pistons
4 the guy at industrial said 1 cp3 modded will be plenty for their VVT TURBO and 30% nozzels.didnt know industrial is doing VVT turbos. you are looking at at least a 72mm inducer to get 800 dont thing a single cp3 will suply enough fuel for that mark regguadles of inj size
5 turbo industrial vvt or cheeta vvt?????? PRICE INDUSTRIAL $1400 NEWfleece has had a bunch of luck with their cheeta turbos.
6 headers???dont see the point fo it yet.
7 trans is already paid for wating for converter ATS!!!

If i had a fully built motor I would not run a a VVT turbo, I would look into a 66-71mm turbo

Why not? 68.5 or 71mm cheetah turbo is 800hp+ capable. Guys are having good luck with these so far, they are huge and spool way faster than GT series. Better on the street and just as much flow as a 'bigger" turbo with less lag....and they are LOUD!

when a duramax vvt turbo makes 800hp show me the video, your drive pressure would be outragous

Don't lie Travis you would go bigger than that:D

Nothing against the Cheetas, but I also agree with Travis,Perhaps it's just something about big turbos that make me, Well um...:eek:


What turbo would you go with? Why would the cheetah make tons of drive pressure? I have a 64mm right now and im getting ready to do the 66 or the 71. Not sure yet. My 64 spools great on the street but i want more power!

I asked Brayden about running his big VVT on my truck and he said the exhaust housing would be the hold up on making the power I wanted, And the 4294 would be area to start.

The cheetah exhaust housing is to small, it will choke you of in the higher rpms. In order to make big power (700+) you have to let the engine breath hence having a charger in the 71mm+ range with a larger exhaust housing. The a5k is a good example, big wheel but small housing and led to bad drive pressure and the turbo dont last long when overspooled

or you can use the Cheetah as the small turbo with a set of twins:D to get your 700+hp

What turbo do you recommend? Ive seen the gt4094 spool and its too laggy but i guess not everything can be perfect.

Travis is right about the 800hp, it would be difficult to achieve that number, I think there's a 64mm in the low 600hp range. I have the 71.5mm right now and have the drive pressure at approximately a 1-1 ratio ;), its all in where you adjust the vane tables, open them up and the drive pressure is very manageable :D

Its all in the tuning, I have ridden in trucks with 4094's that spool wicked fast, My S400 is laggy but it doesnt bother me. I run a 1.10 housing and the 4094 trucks I have ridden in have the 1.06 housings.
