Does anyon know how much you can get out of the ATS housing down the road with 160cc singles and big oil? sorry for the hijack.
The ATS housing only cures surge issues. It does not allow the turbo to handle more boost than it's designed for. If you want to push a stock turbo beyond 25 psi of boost and have it live a longer life, you need to swap out the turbine housing for a bigger one to a 1.0 or even a 1.15. The reason the stock turbo dies at higher boost is because of the small .84 turbine housing that comes on these Superduties. At 25 psi, you are running at least a 2:1 ratio backpressure to boost. Meaning that you have 50 psi of exhaust backpressure at only 25 psi of boost. With such a huge difference in drive and boost pressure, there is a large amount of stress put on the shaft. With a larger turbine housing, you reduce that drive pressure at the cost of additional turbo lag. With the reduction of backpressure, you have a more balanced flow of drive and boost pressures, and less stress on the turbo.
Or you can simply upgrade the turbo to one that can take the power and abuse.
Chance, if you want medium power with excellent tuneability, get hybrids. Hybrids will work with a drop in turbo like the TN ball bearing or the Garrett GTP38R, and also with the H2E. Also, hybrids use much less oil, so the need for an HPOP is not really there like some other big injectors or even split shots. With the hybrids you have a smaller nozzle size, so smoke and EGT's are easier to control.
If you do plan to go with the H2E and want to run stock injectors in the mean time, have your chip reprogrammed by Jody. Jody has a good fueling table to work with the H2E and stock injectors to minimize smoke and turbo lag. I've ridden in a truck with that combo, and the owner of that truck lives here in Colorado. No easy task to get a turbo like that to run with minimal lag at high altitude on stock injectors, but Jody tuned it and it works great. I'm seriously impressed with that man's skills.
Since Im not made of money, and will likely have to space these things out, Im planning on a set of hybrids, and either a cheap van turbo, or a 1.15 housing on my turbo. Then Ill more then likely be itching for a h2e, but before that HEAD STUDS. So IMO the list should go
Tranny
Injectors/ upgrade current turbo
Oem forged/cryoed rods
Head studs
Real turbo
I work out of my truck, and drive it everyday, and tow with it, so the tranny was first. (however it did die when it got worked over) If you want reliability, you better plan on transmission upgrades. Then Ill be interested in some detuned fuel (hybrids detuned). Then as I have pmrs ill be looking for forged rods, that will get cryoed. Head studs, then ill be looking for more fuel (retune the hybrids) and my turbo. I dont plan on more then 500hp. Its just not feasable for me, and it seems reliability starts to go down above 500ish hp. More things keep breaking.
Also, I think 400 is pretty optimistic for a set of 160 stage ones. Beans shows 400 for stage 2s, and 350ish for stage 1s. Not that it matters to me, Im going straight for hybrids.
the guy at swamps told me that a 450 horse daily driver is the most fun you can have. call the people at swamps and they can put together a nice package for you
