Think you have or wrong, run a s300 like a 62-66 as the high pressure and two s256's as the low pressure turbos.

I'm wanting to run it like a compound set-up except for instead of one smaller high pressure turbo I want two being fed by a larger turbo at atmosphere pressure hence the low pressure. The reasoning for it is I'm wanting to go small enough with the twins to have fast spool up and lots of air from the big one to clean it up and lower egts.

 

In. .......

 

The truck in my signature. But wanting to build it as a cheap DIY kit. As it sits not I'm only looking at 12000 and that's included the complete fuel system.

 

I meant in as in subscribed. Lol.

 

Ya what ^^ said. This would be awesome, I have faith in it.

 

If you run it the way your describing I think your gonna have a hard time feeding the lp exhaust

 

sounds like a headache to me, but i intrested to see if you can put it togetr. the only triples i know of are like like 2 64's feeding a 66. hope it works out for you

 

Innovative diesel's truck has been running triples for a couple years

 

THIS IS TRUE, but there truck is not set up like the way he's taklin about. there set up is the 2 64's feedin a 66 ..... i think not 100% sure on the dimensions. but i do know its 2 identical turbos feeding one thats jus a lil bigger

 

Yeah that's how he has it. OP asked about a triple setup and I mentioned Eric's. Craig at MPD built Eric's setup.

 

i didnt no know mpd built that set up, i ve seen it in person and its pretty wicked set up!!! wish i had one ! lol

 

So you want 1 large atmo and 2 smaller hp? I don't think the atmo will ever lite.

 

Here's Tad's triple turbo'd 6L

IMO, you should look to run something smaller for injectors, preferrably not hybrids, or chose a larger turbo to run as you low pressure. I think the idea of usign two high pressures is interesting. I don't think there is much efficiency or spool to be gained with two high pressures instead of one, but it will be cool for sure. I see no reason to question how the low pressure will spool, there is no reason it will spool any different with two high pressure turbos than it would with one. Keep in mind that the low pressure is not operating in the same manner that it would if it was a single turbo and shouldn't be sized as such. I also would not run 40mm gates if I ran any at all, something smaller would be much better suited for this application.

 

Ok guys sorry it's been awhile since I've been on here. Thank you all for the information. I am also questioning the ability of the low pressure turbo to spool fast enough to not choke the high pressure turbos and actually take over on the boost. As far as injectors and sizing I have not made up my mind exactly on the size I want to run but I definitely want to take a dirty injector that cannot be towed with and clean it up enough and have low enough lag time to be able to tow with the setup. I know this entire idea is not practical and it's not ment to be. I'm simply wanting something that I can tow my drag car to the strip with and also run on the strip as well as do some nice smokey burnouts from a roll lol, and when I pop the hood people have never seen it before.

Ok so after some more research it looks like I can still go a little smaller on the high pressure side as long as my A/R is within range of being able to not over speed when the low pressure side lights off. My whole reasoning of the smaller twins is to mimick stock spooling with a non-vgt turbo, as well as split the load between the banks. Also after doing a little more digging it appears that in order to clean up the larger injectors I'm going to need more air but I should be able to go a little bigger on the low pressure side just as long as I go down slightly on my A/R on the turbine side.

Another question I have is has anyone machined out there own oil cooler/filter delete plate that can be used to build a diy oil cooler/ remote filter setup. I'm needing some help on the flow path of the oil assembly.

As far as the gate sizing, what size would be better suited I'm just trying to put together a parts list for the starting point of this whole system.
