Twin Turbo set up?
So I was on EBay today and I saw a 6.5 with a Twin turbo set up, so Im looking for a kit for this but see nothing.... how did he do that? And how much power are we talking with a crazt set up like that?
It had a Turbo on both manifolds. :tu::tu::rocking: GM CHEVY GMC 6.5 TWIN TURBO DIESEL: eBay Motors (item 170548572927 end time Oct-06-10 20:09:56 PDT) This one is all stock inside though. |
not as much as you think. each of those turbos are only making 8 psi. the reprogrammed ecm i will be reciving in a few days i have boost set at 15 psi on the stock turbo. that engine with the same tune would probably make a little bit more power since its two turbos doing the work of one but not a whole lot more. depending on tune and truck probably be putting down 220-230 wrhp. ultimate turbo on my 6.5 would be a holset he351 vgt turbo with standalone controller. best of both worlds there.

I would love have that set up

So exacty how much boost can the 6.5 take anyway? And just how Big of an aftermarket turbo can I fit under there? :humm:
|
15 psi max with mods i do know few running 20 to 25
---AutoMerged DoublePost--- Just took another good look at set did he really use PVC for the piping.......? And then spray paint it shiny silver to look fancy......? Those turbos are definitely chinese/taiwanese knockoffs...look at the font on the data plate. |
playing safe around 15 psi on stock compression. anything higher than that and your playing with fire. guys running lowered compression usually run anywhere from 25-28. as far as the turbo. anything bigger than a hx-35 or A team turbo would be stupid since we cant flow a ton of fuel and cant take much boost.

Compression has nothing to do with it, its the strength of the engine itself. There are many diesels with 21:1 and higher running upwards of 25psi boost.

X-2 ^^^

Not really. I run 18psi boost on 21.1 compression and I have seen several running 25-30psi on the same.
Its the strength of the engine, not the compression ratio. |
