Currently putting togheter the car, and i was wondering if i should go with k24 turbos or a single one. The turbos i currently have are powerstroke gtp38, gt3582r with a .63 exhaust housing, holset big H1C abd a couple k24s. Any opinion is appreciated, id like to use the gt35 but im not sure o the .63 housing.

oh man, excited to see you posting this, because I know that you guys will have a running turbo v8! (unlike most turbo v8 posts which just fizzle and end)

How much power do you want to make?

550 would be good enough i think

The GT35 is a little small for that. It can make that power, but not at the pressure ratio you would be at. Twin K24s would work better.

This is a 40v engine, high volumetric efficiency. Wouldnt it help the gt35?

Actually, it hurts in this case. To make 550 hp you probably wouldn't need to run more than 10 psi. If you look at the compressor map a compressor ratio of 1.7 at a flow rate of 60 lb/min puts you pretty far off the efficiency island to the right. That's not to say it won't work. It would spool crazy fast, but you could wind up with quite a bit higher exhaust pressure (pre-turbo) than boost pressure.

Makes sense obviously... Even with two 44mm wastegates? I guess the pressure would go down easily with them in there.

Yeah, shooting boost directly in the intake, with aome laminova in it. That would save a lot of piping and i can do something that looks somewhat OEM.

It sounds like you need to buy my other 35R and run duals

How much for your 35r? And and how many horses do you guys think can be pulled out safely from the 4.2 40v

Its interesting, i would have to buy the two precision housings, as mine got them and i need to have two exact turbo for this kind o setup. Its not off my mind, but it means much more money. Considering the fact that those turbo united, its gonna have a possibility of 1000whp..... Hmmmmmmmmm i'll think about it seriously.
Anybody has an idea on how many horses this v8 can take before doing rods and pistons?

Ha! This is really nice to hear.
I was given a GT35R years ago and it's lived in my closet since. I know almost nothing about it. And now I hear it would feed a 40v nicely. :thumbsup:
Not saying it's likely, however if I did do something to my current vehicle I'm more likely to buy a stock ford supercharger that someone bought and immediately upgraded.... buuuut...... I have an apparently appropriately sized turbo (and no need for 500+hp) that is already paid for so I guess I'll be doing more research on this mysterious evil closet monkey. :cheers:

Thing is you need a big a/r exhaust housing so it wont surge. Still thinking about putting 1 or 2 gt35... I could run really low boost and get an awesome amount of horses. Still no inputs for the hp this engine can handle!

A couple of people have pushed 500 or so on stock junkyard motors, so you are likely safe to 550 or 600 would be my guess. The rods are a bit crappy so I would suspect that is the weak link. I say you push it and let us all know what the HP limit is....In the meantime build a second motor to drop in when you kill the first one

I think k24's would be a kick. We are building some plug and play hybrids for the urS app using the 997gt2 k24 turbine/compressor assembly, which are pretty close to the Volvo s60r specs. Hybrid hatch on here made 280whp/360wtq before chucking a rod. My bet is that two of these on e85 or race fuel( for compression bump) would net 600whp/break rods tq with virtually little lag like it does on the 2.2L. Problem with a 35r is that you will spool just like they do on a 2.2L(well technically worse, since it is a 2.1L). THat would be in the 4800 rpm range.. Billet wheels would likely drop that into the 4100 range.

two k24's make the most sense to me.
