That ws a good one. Lol

 

Mine screams at me a little with SD ad's topped out. They don't like upper 30s very well at all. I'm going to be making me a t 4 mount as soon as I get a drivers manifold. Not something I need immediately and gives me something to mess with.

 

You didn't quote the rest of what I said. =)

I have all the SD parts for a 38r install already, so why go buy a t4 for stage 1's?

If you can get the SD parts easy, a 38r and stage 1's is a good setup.

If you want more than 160cc injectors, go for the t4.


The issue with t4's is that it can get really complicated on turbo's.
Luckily, people have done the testing and figured out a few good combo's already.

 

I've always thought that these conversations should be explained by what your doing with your rig. Go fast at the track or street, pulling big loads or something inbetween. With my setup it will pull its *** off but I still have to back out of it because of EGT's. I have a IC and water injection but have power left over after hitting EGT limits. So, what good are more mods if I can't use them? Maybe a different turbo would help control my EGT's but like Daniel said, I'm turbo dumb. What are you planning on doing with your truck Daniel, race it or pull with it? That should narrow down the choices, I think.

 

If i'm learnin right, it sounds like you could use a bigger housing, is that right guys? it would let the exhaust pass through faster which would help keep the temps down? as far as my set up, I'm thinkin for the most part, i'm leaning towards pullin (like competition sled pulling) but i'd like to be able to race every now and then... what good is a fast f350 if you can't use it to pull a 36' gooseneck full of horses or a campin trailer?

 

How about a 42 footer loaded to 25K? The D66 works good, I just wish I could leave my foot into it more then I do, LOL

 

I never get tired of seeing you and Darin's big **** trailer pics

 

Seconded.
I feel as if we need to make an estimated amount of miles and weight Glenn has pulled over the years to prove he's "pulled his weight" in this country.

 

Glenn has a go big or go home attitude.

 

I thought it was more of a "Bring big home, Go Anywhere" attitude

 

Because there are more options with a T4 mount, and the turbos are more efficient. But you already knew that from past threads on this topic

With my stage 1's the stock turbo is screaming for relief on a hard run. I wouldn't feel very good running a stock turbo on stage 2's for very long... unless you can keep your foot out of it. But if you're putting stage 2's in, you're not gonna want to cruise around at 1/2 throttle or less all the time.

Good point!

S366, modded H2e, QSSB. Maybe a GQSSB or GT4294 if you go to hybrids.

 

I think Glenn is a retired train engineer, if so, he's pulled more weight and logged more miles than all of us combined!

 

The guy I bought this from raced sprint cars so its extra tall.

My camper weighs 16k but this was 25k loaded when we moved from Ne to Az. I pulled over a grain elevator scale and was shocked when the guy handed me the weight ticket. He of course had a dodge cumming and we had to talk about that, LOL I just cringed every time I went by a weight station. It was surprising to me how nice that trailer handled, I wish my camper had thriple axles.

That's how I convince my wife I need more MODS!!!

When you live in a camper six months a year we need space to get away from each other, know what I mean??

Thirty years, I don't like even looking at trains anymore, burned out. These loaded coal trains are the world's largest land moving machine.

 

In Glenn's case, exhaust back pressure and boost pressure would need to be checked to determine if the exhaust side is too restrictive. IF backpressure is rising when he's pulling hard, then yeah he could benefit from a larger turbine housing or a larger turbine wheel. You want the boost to drive pressure (backpressure = drive pressure) ratio to be at or close to 1:1. If your seeing 30psi boost and 50psi drive, then some turbine modifications or a wastegate would be beneficial. Going to a larger turbine housing could cause a problem though with slower spool up and causing it to blow some smoke during spool up, which from what I gather Glenn wants just about ZERO smoke from his rig. The smoke could be held to a minimum through tuning, but he would have less power during that time and I don't think he wants that either. A wastegate would allow him to keep his fast spool up and allow some of that extra pressure to bypass the turbine and keep boost to drive closer to 1:1.

The other thing is he may just be pulling extremely heavy. When you pull as heavy as he does, it's going to be pretty tough to get to stay down. He could actually probably benefit from larger injectors with larger nozzles with proper tuning and a good turbo to match, but that's a whole different can of worms.

For stage 2's, I would run the S466 in the configuration I listed before all day. The GQSSB is a good S300 charger, but they are pricey and you can only run a T4I mounting kit. That limits your turbo options down the road if you ever want to switch. Same with the modded H2E. It's a great turbo for stage 2's and hybrids, but if you want to switch down the road to a different turbo, your stuck getting one that will mount to the T4I flange. Nothing wrong with that, just limits the turbo choices a little.

For hybrids you could still use the same S466, but depending on nozzle size, I think a step up to a 1.10 turbine housing would be beneficial. Other options would be the S471 with the 83mm turbine and 1.10 housing, S467 with the same turbine setup. The S467 has a billet compressor wheel in it that flows pretty close to the same air as the S471.. The Garrett GT4294 is a good turbo also, as Chase pointed out. They come in two versions the GT4294 and the GT4294R. The "R" versions are ball bearing turbos and should spool a little quicker than the standard journal bearing turbos, but the ball bearing model is quite a bit more expensive and is not rebuild-able like the journal bearing turbos are.

In the end it comes down to how you want the turbo to react, how much power you want, and if your sled pulling, class rules will limit what you can do with the turbo, so we'd have to know what class your going to pull in and what the rules say about turbo limitations.
