Hey guys, doing some homework on a project of mine and need input. Your experiences or even what you've heard could prove very valuable. Need to know, with as much detail as you're willing to provide, where the failure occurs when pushing in excess of 10 psi of boost to a 6.2. Thanks in advance for the picking of your brains.:help:

I have NO experience with boosting these motors, BUT my reading indicates that excess of 10psi heats up and stresses all components of the 6.2 excessively. those that have boosted higher, seem to lower the compression ratio with dished pistons, and ceramic coat them. also they add oil coolers and gauges to keep an eye on exhaust temps. 19.75:1 CR is one I have read of... I bet it's a BEAR to start after 100Kmiles...

my buddy has one that he originally put a 6.5 turbo on. then upgraded the turbo and makes 25psi.

My intention is put 20-30 psi to one. The first thing I am doing is to make a bedplate for the block and possibly put in 1-2 inches of block cement in the bottom. Not sure yet whether or not I need to be concerned about the crank thereafter. Head studs, of course, and either steel laminated head gaskets or machine groove ring. Contemplating supercharging rather than turbo. I am waiting for the combined knowledge of all of you before I finalize anything.

Do some math about the cylinder pressures, IATs and cylinder temperatures from compressing the air alone you will have to deal with at 20--30 PSI. Some new head studs and gaskets won't hold up to that ...

yup pretty sure i wouldnt do 30 psi

I'm planning on piping hho to the intake valve, so combustion temp will be dropped and timing can be retarded. Ok, so 30 is out, how 'bout 29:lol:...that does make for a lot of cylinder pressure....hmmmmm.....

How about 12, with an intercooler? It might not last long, but you could try ...

How much does an intercooler help with EGTs? Mine runs hot at over 10k ft but in town the temp is normal, ~190-200.

That depends on the size and efficiency of the intercooler ... TurbineDoc should know, he has one on his 6.5.

i was just wondering how the hho will lower the egt since you are still burning the same amout of fuel from what i have read that the whole point of hho was to use less fuel and hho to make the same power but i may be wrong if you know i would like to know i have built a cell myself amd am plainnig on using it i have done some testing with the 2.5 in my jeep and it is working pretty good after i put the efie (eletronic fuel injector enhancer) on it helped out a lot the little bastered has more power but i did not see that much of an increase in mileage though

Cell gas output has a lot to do with affect on mileage. And you'll use less fuel in the sense that you don't have to stick your foot into it as much, because the hho promotes a more complete burn of the fuel already entering the combustion chamber. Ordinary fuel, you only get 20% of the energy potential from each molecule of fuel. The rest is lost in heat. The more complete burning of the fuel with the hho means less energy loss in heat. Not to mention the flash (burn) temperature of hho is much lower than gas or diesel. As far as the gas mileage goes, a basic cell will not do a lot for mileage. How many cells are in your generator?
