Twin Turbo Parts Links and advice

[Tacoclaw]

I am actually curious if it is actually heat soak from all that hot metal that makes the coolant get so hot. I realize that there's now 2 obstructions in the exhaust tract, but surely with the 3+" hotpipes and 4+" downpipes the exhaust can still get out fairly quickly.

I looked around and found a T6 turbo blanket, but I'm having trouble finding one for a 'gated S300. They have "T3" wraps, but I had a T3 turbo on my Ranger, and it was 1/2 the size of my S300, not counting it's giant internal gate casting.


Also, SNOOT, I don't know exactly how many and what kind of miles your truck sees, but there's quite a difference in a truck that tows a lot and one that sees light DD use like mine. A lot more vibrations and heat involved in that kind of work.

Don't get me wrong, Ellis, I think it would be awesome to see another set of twins out and about. Especially in a working truck.

However, I can't help but think of that ever-applicable acronym: K.I.S.S.

I think it would be cool to pop my hood and see two turbos hanging there, but I was also looking at this for practical purposes,which may not be there
I've seen where people have singles and have problems towing with them. Then again some not. KTA said,at point in my time reading in this forum,that he hauls with a truck with a HX40. I was under the impression that with the 60mm inducer on my H1 that I had, essentially, a 40 minus the 4" exhaust outlet. Is this wrong?
Reason I asked about turning the fuel screw in is I was thinking that maybe I'm not spinning my turbo fast enough ,or something of that nature, to actually benefit from its increased diameter inducer. I am on the stock fuel and it did push 19lbs before so could that be a possibility.
I know that its not just the pressure that your running in boost but also the volume of cool air that's coming in, so maybe I should look into another area as suggested like an intercooler. Or maybe the exhuast, upgrade to a 4" system?
I realize there's more upgrades to do to my truck than to just jump on a set of twins, that's why I'm asking . I don't really want to learn the hard way by throwing a bunch of stuff on there and still have a problem. I've done that before and the cost was low, with this there's nothing cheap about it. Not to me anyway

[ellis93]

Did I say something wrong

[dazedandconfused]

I still can't see personally how a single will cool towing heavy. I think your initial idea would be the best for towing. Everyone I know who has tried to tow with a 62 complains they don't see much difference over a HX35. Your not wanting to go crazy on fuel so I think it would work.

I still say a ported head would be a good middle step in keeping one of these trucks cooler. Unfortunately, I'm not sure what porting can be done to the intake side without milling off the factory intake. I assume once you get into that territory, the money starts adding up fast due to needing a custom intake.

Do you still have the factory intercooler? It doesn't say otherwise in your sig, so I would think a more efficient 2nd gen or PS intercooler would help out a lot.

I don't have much to say on the topic of how to make a working truck, as I don't have one. I'm just basing my opinions of twin complexity on my experience so far of fabbing mine up. If I was towing some 19klb load for $$ and got an oil/water/boost leak, then popped my hood to work on it, the last thing I would want to see is a 1000*-400* wad of piping in the way of what I needed to tighten up.

[ellis93]

Ya it still has a factory I/C in it.
I'm still wondering about my turbo that I have now. With the bigger wheel on it is it still in its rang of efficiency? Should I add fuel just to make it spin faster to pump a little more air. Or does that make it worse, I'm sure a bigger i/cooler would help but if I'm not pumping the proper amount of air then I've not solved anything.

[Tacoclaw]

[talking out of ass mode]Since you're towing, I would think that just having a turbo with a 4" outlet would be more important than being able to stay in the map. 30PSI is probably getting pretty close to the edge, but it's not going to be a game-breaker. It's not like you're going completely off it's map or something.

Even if you put a 4" exhaust system on it, you've still got to squeeze it out of a 3" hole. I say that a complete turbo upgrade is in order. I like my 62/65/12, but I'm also going to say that my 18cm H1c might have spooled a little faster. Smaller wheels=less inertia, so it makes sense, but the S300 keeps it a good bit cooler up top.

If I had it to do all over again, and a twin turbo budget to do it with, I think I'd look into some of the ball bearing Garrets and Borg Warners coming out nowadays. They're making super light and efficient wheels, built in wastegates that rival external 'gates in their flow capabilities, water cooling, and just better layouts in general. They're pretty expensive, but not too much more than some others.

I don't know about a" dual ceramic ball bearing cartridge". It was also said there that a breeze could spin the turbo too. Might be wroth looking into.
I'm gonna see if I can find a dealer to get a price.

[Remps]

Turbonetics has used ceramic ball bearings for quite a while. All EFR series have a 3" V-band turbine outlet, might work well in a twin setup.

[Tacoclaw]

Well, I kind of meant twin time as well as budget.

I figure it will take a decent amount of time on the phone with a tech telling them what you have now, what you're wanting to do, and what your other options are. These turbos seem to be aimed at gasser performance. I looked at a product lineup and the closest I saw to some of our go-to turbos was a 70/55/.80 AR. I think that .80 is around a 14cm, but that's a pretty small exhaust wheel.

They may not be useful to our trucks at all, but the first thing I'd do is explore some newer technology options.

Got some emails sent out. One to Jkidd about this:
http://www.cumminsforum.com/forum/diese ... 100-a.html
I wanted to see if its still going. Been awhile since its been active thou. Worth a shot.

[ellis93]

Well my E-mails seem to be proving less than interesting to some dealers One of the two that responded basically told me that there was no way I could run twins and pull with a VE pumped truck I responded with a couple of links to treads I've seen that in fact had twins and pulled. I've had no farther E-mails from him and really doubt I'd do business with him now any way. I'm now just waiting on a reply from Jkidd at http://www.dieselautopower.com/ I've so far sent two to him alone, just to ask about the kits he had offered almost a year ago. Guess I just need to pull on my big boy drawers and fab out my own pipes since my money is not green enough

The thought of someone wth a Yosemite Sam avatar putting on big boy pants is pretty funny.


I had great luck with Jkidd back when I bought my turbo. Have you tried PMing him on Diesel Bombers yet? That's where I had the most luck getting ahold of him.

Fabbing twins isn't that hard. If Hineman can do it anyone can!

[AHineman]

If Hineman can do it anyone can!

Man Levi, always gettin' on the people that help you out.

I was really just going for shortest down time with buying a kit. I can fab one out, I even have the tools to do it to boot. Problem is I've more money than time right now. I'm sure that will change.

As far as Jkidd goes, I'll wait for awhile

Oh and Yosemite Sam has to put on big boy drawers too
