Random question and ,BTW, I hate you bastards!

I think it's OK. Some say they are happier here, others think we're in junior area...

I would rather say not enough time has passed may be to heal some wounds.

That's all personal opinions, not worth opening a can of worms here, enough done on another place, this one is quiet and I think wisdom should say "OK, enough"

BTW restoguy, glad you find us ;)


Why would you like to have a central turbo setup ?
 
Unless the central turbo sits down in the valey pan there wouldn't be enough room to clear the hood on most of our trucks, not to mention the firewall clearance issue.

The hummer and vans use them because of space limitations on the body design.
 
There is a ton of hood clearance on our trucks, and IIRC there will also be a ton of firewall clearance. The turbochargers on the van don't sit exactly where you'd expect them to, they are pretty far forward. The only interference I see is not being able to use the stock downpipe from the van setup.
 
I can see wanting to equalize the exhaust pressure, and improve the efficiency, but I'm not sure the gains would be worth the trouble. If you want to, go for it; maybe you'll start a craze, fad, or movement! I'm interested!

NOT ANOTHER WORD about the other site vs this one... from me. ;)

A TON ? then why did they not use the center mount in the first place? They made two different designs because ? I guess I just don't understand. You would think that after thirty years of working on vehicles for a living I would have at least learned one or two things, guess not. And I have worked on a number of GM step vans with the 6.5 in them, never realized that there was a ton of room , or the intake was completely different or that the turbo actually bolted to the intake, or that the injectors were shorter: must have been asleep when I did them. Guess I should pay better attention.

I guess I should have defined a ton, sorry. From the bottom of the intake mounting flange to the bottom of the hood brace is 10" (measured at front of cylinder head) and the same measurement, taken near the back of the cylinder head is 14" and at the very back you have 11".

I don't understand many of the things GM does either.

The vans don't have very much room at all, I was talking about the trucks, sorry for the confusion :)
 
It's much cheaper to cast an exhaust manifold to bolt it to, than build a center mount, on production costs. They only did it on the van and Humvee because they had to.

I've said for years; mass production can lead to cheap products. Save $10 per 100,000 units, and it's a nice bonus for the suits!
 
I am basically a Newbie and am not offended by this thread. I think it's a great thread and to delete post just because someone is offended is being way to PC. I have been out of GMC truck Diesels for about 6 yrs. Six years ago there was a very limited selection of Diesel forums on the web, Now there is a great selection. I have been cruising the site and lurking but, I had to speak up. We are Truck Drivers, no let me say it again, we are Diesel Truck Drivers and are use to saying what is on our minds. Let it be so!!

There is quite a history that you probably don't have 3.5 inklings about here. And you need a dozen to have a clue. Feel free to speak your mind, but it is best to know what you are talking about, or run the risk of lookin' dumb.

He's good. I had a brief PM exchange to fill him in.:thumbsup:
 
The reason I asked about center mount turbos is because I'm starting to play with sequintial twin turbos. If I put one in the valley, I can put the other on the fender. If the van setup fits into a truck, then it's that much less custom fab work I have to do. I've done my share of work on 6.5's, but never in a van. I thought there might be a chance that someone had tried to put a center mount in a truck and could give me a little info. I don't have any van parts handy, so I'll have to buy them to find out if it works or not, unless someone happens to know from experience.
 
Just a few words from your friendly neighborhood JiFaire...

- Dave is good people. Nothing here was shot at him, and that was made clear. Some others might want to look at that and wonder why people stick up for him.

HINT: it's because he earns it, by how he acts.

As for deleting things here, or censoring the thread, give your heads a shake. That there is one of the big reasons why this site is the way it is... something that could be learned and copied, should it be desired.

Don't ask us to censor things to make it look like censorship is normal. Won't happen.

Marauderer: Speak your mind, friend. You don't run the risk of looking dumb - we will help you to fill in the blanks. We don't get smarter by repeating the mantra, but by seeking the truth.

Gentlemen all... keep this on topic; (centre mount turbos) - you can talk about turbos here - please enjoy the freedom to do that.

Jim
 
:mad2: ):h X2, Mr, Jifaire past is past as long as we learn from it. The past got us to where we are, so it is a positive thing.

Now on turbos: where are we going to fit these compound , sequential, parallel and stacked turbo set ups. From one turbo to multiple turbos wow, excellent ideas. :thumbsup:
 
Jim, Thank You.

As for the center mounted turbo to support a twin turbo sequential set up. The hood scoop is not a difficult install. I have done a couple. The most notable was installing a 4-71 supercharger in my 83 Z28 Camaro. The hardest part was making it weather proof as the back of it was open.

How much power are you looking for Restoguy out of the 6.5? Have you considered a Duramax intercooler/charged air cooler for your motor?
 
We have a 6.5 running 25 psi boost with a Duramax Charged air cooler and a Garrett hybrid ball bearing turbo push 320 hp. IKt is in a 3500HD service body welders truck with crane, aircompressor, etc weighing in at almost 16K lbs. It is a Killer 6.5 and only has one turbo.
