Truckers, lets see your rigs!

Since we're doing retarded things to Detroits, what's the take on keeping the w/g Garrett and pairing it with a billet wheel 171702 or would it be better to go with something in the 78/80mm comp range?

Thank you. I got a lot to learn before I do it. The fab work I can handle. I just want it done right:thankyou2:

Always have to remember the small high pressure turbo goes on the manifold.

Massive waste of time. A billet 171702 or even a cast 171702 drive too nice with the proper tune. An S471 over an S485/1.58 housing does very well, though. Just an expensive setup in the end for an engine that really can't take advantage of what it has to offer power wise.

Here's a better question: Does anyone actually offer a billet 75/100 wheel that outperforms the stock cast? I've tried two and can say those definitely DONT.

Yes, excuse my ignorant terminology. What I meant was an Acert-like setup, but with the turbos mentioned. Your pic explains it much better than my words.

You don't think a series 60 could use that air reliably? Maybe not a stock internal one. What would the hp range that setup would be capable of producing?

I wanna build up a series 60 for my truck when I get the chance and was wanting to do twins. But maybe a smaller a/r than the 171702 for the lower end? When the time comes I wanna plan it out obviously injectors cam, pistons an that.

If twins are such a massive waste of time, why would you take the time to put them on B and E model Cats?

It is a massive waste of time on a 12 Liter detroit utilizing a turbocharger that works perfectly fine as a single on that particular engine as the atmospheric turbo. IMO they are a waste of time on a 60 series in general. Not bashing, as I like the engine for what it is.

But a single works perfectly fine on a C15 also, it just has a narrower power band (which a Detroit already has). I want a 1300-1700rpm capable Detroit.

You also wouldn't use a 78mm S410 borg as the atmospheric in a set of compounds on a C15.... I think you are selectively reading the conversation. I wouldn't use a 171702 borg that is perfectly capable by itself on a 12.7 detroit 60 series as the atmospheric turbocharger in a set of compounds for that particular engine.

Put a decent tune on it and a 171701 or 171702 borg. Done deal. Or leave the stock turbo on it and put a decent tune in it.

It's called a compound turbo setup. Not to be confused with twin turbos. But the cat one wasn't very good for a lot of reasons.

Just for the s ake of clarity are you talking an 01 or 02 in compound with the wastegate turbo or in replacement of it?

To me the 01/02 turbos are ok, but there are better options out there. For most they're perfectly fine though and excellent value for genuine pieces.

Well that's why I asked if an 80mm would be better in place of the 75.
 
Quite frankly it's a power thing, no one is using home built compounds on C15s below 800 to the tires.
 
I made 476 RWHP with the fan on steady state. EGTS maxed out at 920 at 1500, 1650, and 1800 rpm being held there for 5 minutes each time. At 1950 it went up to 956 but that's a function of the compressor map not too much fuel. Who the hell runs that high anyways. I have the fuel map just about perfect. Zero smoke too and it spools great for a non wastage turbo.

They were having a safety blitz so I wasn't allowed in the dyno room. Anyone have any idea how much power the fan on cost me?

Prob 20-30 on the fan. I would have expected higher from a tuned truck as my non tuned rebuild did 443 to the tires.

This was the short way around to what I was saying. A 500hp detroit, cat, cummins you name it doesn't need compounds to be safe and have great low end power.

As smokincat said here, we don't build compounds for a Cat to make stock power.

On what dyno?

434 on wajax/443 on toromont winnipeg

434 was break in dyno the 443 was because it eats oil like a pig an the mechanic wanted it done to see if it had blowby before he dug deeper into it
So 443 was at 20,000km on engine and it ate 6 litres of oil in 2800km at that point. Slobbering out of turbo on the dyno.
