someone should try it

I think I am looking at this in a different light than you are... but I believe were seein eye to eye now. I immediately jumped to thinking this would be for big performance and big power gains, but you are thinking about just optimizing a stock fuel truck.... Say somewhere in the neighborhood of 650 horse? i think that would be a killer idea. Basically just moving more cfm through stockers to lower temps and increase power at the same boost pressures. With added air more psi is possible.

What kind of boost numbers are stock turbos standing up to these days?

The most people are seeing is 52psi or so on the big tunes. That is about the highest I ever saw.

If I had a 6.4L Dustin I would do just what you just suggested..

I think it is a killer idea..

Agreed. MPI does something similar with the Dmaxs too don't they?

Seems like the only reason to gate the atmospheric would be to keep the PR down in between stages.

50-55 psi probably making alot more heat than anything

I was kind of in the same boat as you JD. Was thinking in terms of increased power, but this system would optimize the most performance out of a stock truck.

Lol damn us and our want for performance!

alot of companies make compound kits with a stock turbo, or a modded stock turbo, keeps them safe to drive and tow with, but allows for more hp, yes it may restrict top HP over a bigger twins set up but for a street truck... forget about it.

Im actually thinking it would work on a stock fuel truck with one gate, or work on a heavily modded truck too, im thinking 800 hp if the atmospheric flows enough air...

REALLY? How do the stokers keep up? I mean at some point the amount of air being forced into them by the atmospheric become counterproductive at some point wouldn't it?

Yes they are (well from what I have gathered they do). They do the same thing for the dodge cummins to.

 

[Dzchey21]

think about it, run a billet 82 like the max powers, they are capable of 800 hp, i dont know why a 88mm garret or something couldnt do the same

I think its possible, but what do you think about that much psi and egts? Do you think with as far outta the map as the stockers were it would start to get hot?

Dodge and Chevy's out flow our heads by quite a bit. Wouldn't that hamper things also?

 

[JAP]

How retarded would a "dummy" turbo be for these trucks? Something that could be had for cheap, but allow the stock atmospheric turbo to be used as the high pressure in a setup like this? Something larger that would allow for more flow than the stock hp? I imagine that would defeat some of the purpose...

 

[Dzchey21]

not really, it just means that they can run more hp at lower boost levels, so the turbos stay in the MAP a little better as a single, since we need boost to make power, might as well split it up in three stages, tractor pullers use it, they are pretty tight lipped about it though

Not realy.. It would be quite possible. Air is air. When you compress the air going to the stock turbos, It is more dense and has more oxygen in it. Then the stock turbos compress it more so you get even more oxygen and air into the same space.

Its all about air density.

Your right it would the whole idea of keeping the stock turbo which happens to be a vgt, so you would loose spool up, This thinking would be better off just doing a single turbo kit, and a big atmospheric turbo


I cant wait till charles reads this LOL

AAhhhhh I see. The one thing I don't know is turbos staying within the map. I don't know what that means. :morons:

Not entirely..... compressed air starts to heat up...

I was thinking the same thing.
