Ok first off, i didnt know where to put this so re-direct as needed.
Heres the deal, a buddy of mine here in Killeen,Tx has a dyno and its the only one for quite a ways and im trying to get him to get the stuff to dyno diesels. So the question is for all of you that have been to a shop that dynos diesels, i need some idea on how they vent the exhaust. I.E. Stacks,reg., duals, and whatever else kind of exhaust that is ran. I need to know what kind of tubing and where you have seen it exit the building. (out a door, threw the roof, underground, and so on. Thanks!

 

You don't like the smell of Big Black Clouds of Death?

 

The ones I've been to, two of them had the rear of the truck to the open bay door. One used a slip on pipe over the exhaust, the other just let it go naturally. The third shop had the trucks back in, and slip over pipes and fans blowing the smoke out. They were only setup for doing single exhausts.

 

Some shops don't vent at all. Others have the dyno close to a door. But if you want to keep things clean inside, ventilation is the only way to go.

The shop up here in Emory has a system that is vented through the roof. They have an exhaust fan set up in the system and pulls from the tailpipe and discharges through a stack through the roof. They have provisions for vehicles with stacks as well as rear/side exits. The tubes have rubber boots over the ends to keep from scratching things up.

If your dyno is close to a door, you can also just use some flexible tubing to direct the exhaust outside.

Or you can be like HPP in Lewisville and do nothing. You back into their shop for the dyno and there is no door behind it. So that shop fills with smoke anytime a diesel runs.

 

I dont mind it even though it does stink, but the only way he will consider it is if i come up with a vent system and build it for him. May mean free runs for me...

 

Sounds like a good deal then.

 

YA just get enough length of hose big enough to exit the outside of the building and let set. and let hang over the exhaust. if duals, get two. Thats what i have seen.
