Stacks on a turbocharged engine??

Most people can tell I'm new to this by the stupid questions I ask, but I just don't know.

How do you put dual stacks on a turbocharged engine with a single exhaust from the turbo. [img]images/graemlins/chair.gif[/img]

By the way it's a 94 F-350 supercab longbed diesel
*just in case you needed to know*

Re: Stacks on a turbocharged engine??

Use a "Y" pipe, only in reverse.
Single inlet, dual outlet.

You might want to check with some of the high-performance diesel websites.
I'm sure there's a formula for determining the best exhaust.
Playing around with the exit from the turbo is asking for trouble if not done correctly. [img]images/graemlins/crazy.gif[/img]
They're designed for a certain flow to spool the turbo up.

Re: Stacks on a turbocharged engine??

Oh yeah, you said it WD-40. got to be careful, not only for proper turbo "spooling" or "winding", which affects response and power, but also for longevity. Turbos are sensitive to temperature. Maintaining proper temps in the exhaust is important. Is this truck intercooled?

Re: Stacks on a turbocharged engine??

When I was in Hawaii I was talking to a guy who had both of his exhaust enter a single piece of 4x4 square tube steel. The ends were capped and plumbed with 3" stacks on each end. All I could think of was "Cool!" It sounded cool and the guy said that it ran great. I think some custom Body work had to be done to the bed to make it work but it sure as hell looked cool.

Re: Stacks on a turbocharged engine??

got a question though when the engine is not running where does the water from a rain storm go if it enters the pipe. gravity works and when the water level raises I really don't want water in my cylinders. [img]images/graemlins/beach.gif[/img]

I could probably drill in a hole or something but I don't want to do that for fear of stalling in water and the water running in which (besides looking cool) is the reason I want the stacks.

Put some big ole flappers on top of the pipes, like tractors run. [img]images/graemlins/shocked.gif[/img]

Re: Stacks on a turbocharged engine??

yeah I was thinking about those but I figured that they built up extra back pressure. Because I've seen some semi trucks with them but them trucks have bigger engines and a lot more exhaust to push them things up. on one stack I could make sense of that but on two. Does the engine have enough exhaust pressure to keep them up or will they build up pressure until they pop up.[img]images/graemlins/confused.gif[/img]
