if i put a dozer turbo or a semi turbo on my exhaust and mount it to the frame under my bed and hooked it up right and have it push air into tha exhaust so exhaust comes out fast would it have any improvement? cuz im gonna customize my exhaust into a 4 inch pipe that goes from the manifold and go right under the bed and drop at the axle?

Sounds good to me. Tell us how it works out.

well im gona run a 4in exhaust to lets say the front of the bed mount a turbo around there mount it to the side of the exhaust so exhaust goes in the turbo and u kno tha rest roll a pipe from the turbo down the side of the exhaust pipe so it pushs air into the exhaust and for the intake on the turbo run a pipe or plastic kinda like a snorkel and mount the pipe to my headache rack and then after that have the 4in pipe go to the axle and have a 45* degree bend so does that sound like an idea that would work cause im just young and coming up with ideas for my truck??

Well I am glad to see you have lots of ambition and ideas, but I think you may need a little direction on this plan. Your idea of speeding up the velocity of the exhaust to create more power is valid, but you may be attacking it in the wrong way.
The problem is that by adding a turbo inline of your exhaust you will likely create more back pressure than you will add by plumbing the boost back into the exhaust, especially with a very large turbo such as the ones generally used on large industrial and highway equipment.
Those big turbos take lots of exhaust to spin up and create boost, which is not a problem for the very large cubic inch engines they were ment for, but your 6.2 likely just won't be able to efficiently drive it.

You are on to something though, don't get me wrong. There are systems out there that replace the muffler with a turbo and then plumb the boost back into the engine. Usually this is done due to lack of room for the turbo in the engine bay, and I also think it would help keep temps. down slightly. You would defiantly gain but adding some boost to your old 6.2, and effectively making it more efficient as it will be able to move more air in and out of the combustion chambers. More air in = more efficient burning of the fuel = more power.

This is just my 2 cents, and if anyone has anything to add, please do. I don't pretend to know everything! :rolleyes:

Keep up the thinking and the ideas, everyone has to start somewhere!

yea you don't want the boost going to the exhaust, you want the boost going to the intake...but a dozer or tractor trailer turbo might be overkill for a 6.2 you might be better off looking at mid range truck turbos, lots of guys in the 6.5 forum have turbo swaps in mind and also a few have been done, but theres little to no point in turboing the exhaust...just my .02

well im trying to think of ways around gettin the banks turbo system but i see wat u guys mean by having to big of a turbo so idk

do u guys have any ideas????

If i am reading right, hooking a turbo from the exhaust to go right back into the exhaust will not help things, because nothing is 100% efficient., plus i don't see how that would even do anything. If i was you, i would mount the turbo some where along the line of you trucks exhaust, and then feed the air coming from the turbo to the intake manifold of the truck engine. The positives is that is would be easy to mount the turbo, it would keep oyou engine bay less cluttered, and that the distance the air travels to get to the engine acts like an inter-cooler. The negatives is that turbo-lag would increase by a bit, and that you would have to get long oil lines for the turbo.

so should i just go with banks sidewinder system?

Right, get a turbo that is sized for this engine.

On the other hand, I've heard quite a few stories of turbos blowing up 6.2s.
Depending on the age & upgrades of your engine, you may or may not want to turbo it. Depends how long you really want it to last.

the sidewinder kit, should you be able to still get your hands on one, has been a more than satisfactory upgrade to most peoples 6.2's...keep in mind in your case your dealing with a first gen 6.2 and we have no idea the mileage, you may have a weak lower end just waiting to crack....not to be the harbinger of bad news but your best bet before adding any turbo....specifically an BIG turbo...you should have the engine inspected closely...

thats a good idea because my truck has been rediald twice i think and it is pretty much been weard out so

I think I would abandon that idea. way better off putting boost into the intake than the exhaust. And your planned turbo is way to big to be practical. the donors you mention are likely 3 to 4 times larger than your 6.2. like in the neighborhood of 900+ cu in. find a smaller donor, like a turbo from a 3.8 turbo buick or trans am or many other possibilities. mabey from a 5.9 cummins?

for your platform opening up the exhaust to 4" will greatly increase flow posibilitys as well as keep EGT's down, you dont need to boost the exhuast as for adding turbo i assume your wanting to increase power which is great we all want that but the unfortunate side of that is you will want to make sure that your engine can take the added power first and foremost, once that is acertained then look at a pre packaged system built for your engine, as messing around with differnt turbos andsuch can lead to expensive miscalculations, and if your not familer with the engines idiosincrocys you could likely loose your eninge completly. as for the turbos from the big boys, well there built for engines as big as the front of your truck while the air they put out is awesome and would give the 6.2 a good kick in the pants the exhaust that is need to spin them babys up is considerably greater then what the 6.2 puts out.
