my mind goes to strange places when I have too much time on my hands. If you were to build a vehicle with 2 LS7 engines you would have 14L of displacement to utilize. I was looking at large turbos and it seems that options get pretty limited when you start looking at the amount of air that needs to be moved. So I started looking with more of a industrial mindset. Train turbo are massive and support huge horse power numbers. Any thoughts?
on a side note I found a train video on youtube and the comments gave me a good laugh

Are you saying strictly one turbo to run both LS7s? If 2x then PT106s or similar if 4x s480/76s and make 3500hp!

I think he wants one turbo for 2 LS7’s. Maybe like a tractor pull multiple engine set up?
I feel like the exhaust routing for one turbo and the insane lag would be big downfalls.

The better question is what size turbo would you need for 2 SHO motors and still be able to fit them in a Camaro.

Silly idea. I did have a thought though, I can’t find the specs, but this video shows a large Detroit Diesel 6v53t. Got the idea because my father had these engines in his old boat and I always thought the turbos were enormous. It’s got a pretty large turbo, but it doesn’t really look much bigger than some of the high hp muscle car builds I’ve seen on here, so probably a bust in terms of finding something “different” for you. I do know that the 53 Series diesels also came in a 12 cylinder config, but I’m not sure if there was a turbo variant of the 12cyl. Either way, I went digging so here it is on the 6 cyl variant,

Looking for a single turbo solution 2000-2500hp potential

For 2k hp you can do that with one motor and one turbo.

See above. You can achieve that power goal with 1 motor and 1 turbo. Anyhow to answer your q im not really sure what would be used if you want to run both motors with one turbo

Is this a crack-pot idea to mate together two LS Engines to create some kind of W-16 motor? Strangely enough, I was just looking at a thread on a wakeboarding site (of all places) of a guy mating together two 1JZ motors into a 12 cylinder motor.

Still, if that’s your plan, better off running twin turbos than 1 single.

This application would require 2 engines to remain practical. And i just like the idea of running a huge turbo instead of 2 normal size ones. I know they exist, but finding marine and train drivetrain info is not the easiest thing i have done.
Edit: i keep finding stuff that would not work on a gas engine like turbos that are way way too big or run a 7:1 or 8:1 pressure ratios

Maybe if you can get some of us excited about the application you’ll get more helpful responses.

I heard he’s mating 2 sho engines and looking to make them diesel powered for his Camaro.
