Well I am still around. Thanks for the trash talk as usuall. The cougar is sitting retired from daily service for now. I bought this as my new daily driver and another turn key Detroit diesel swapped 48 gmc for another toy. I have been busy lately to even touch the cougar.

Yes I do. I don't drive it often the powerstroke is my daily obviously. It has a freshly rebuilt 2 stroke Detroit diesel 4cyl turbo. 4 speed with a 2 speed rear. 1 ton running gear. On board air and setup to tow anything. Here's a short clip of it running.

Actually it is some kind of stainless steel flex tubing. Works well and holds its shape. I kind of want to know where the builder bought the tubing. The smoke stacks are aluminum. Here's one more short clip of the lil old Detroit reved up.

Emission testing be damned! I bet you have to answer a lot of questions about whats under the hood.

Wa only tests for 25 years then a vehicle is exempt. not to mention I am out of testing area anyways so I don't do any testing.

Right now it has a collecter plate which can only really be driven on sunny days. Also it has a very stiff suspension that's not daily driver friendly. I went too fast over a railroad crossing and bounced the rear of the truck a good foot off the ground. I dropped a 600 lb motor in the bed and the rear sunk less than 1mm. My 7.3 powerstroke is a strait piped 5 speed which makes for a fun dd.

I love all of your cars right now! The GMC is very cool and I would love a 5 speed PSD! Hopefully you can finish the cougar soon, you have enough diesels for now!

Thanks. Also when the weather gets better I will get to work on the cougar. i have no garage right now and its raining everyday. The covertor has been shuddering for the last two years so that's first on the list then a turbo and probably blow up the old tired 4.6. The ultimate goal is still a diesel powered cougar...someday.

Well. The cougar is on jack stands. Work is back underway. Hope to have hotside done by this weekend (weather permiting). I am U-turning the exhaust where the 3rd cat was (now a muffler). There will be several custom mufflers that I built infront of the turbo feed that are already in place.

So, we are back into running a custom turbo setup to blow the motor up?

Likely won't blow. I'm only going to run 5lbs of pressure. The turbo has a large housing that should keep egts and exhaust backpressure down.

Why would you put a muffler before the turbo ?

It will rob a small amount of effeciency but nothing I am worried about. The hotside will bolt to the factory 2 bolt ball flange. Then u turn towards the front to where I left off. This allows the stock exhaust to be place back on the car in seconds and there is not much room for a muffler after the turbo. Its going to be kept in check at 5psi. The worst that can happen is a small lag in spool up which can be also changed with a few changes to the turbo or change the turbo for a better one. The mufflers already equiped are all custom. Two strait thru bullet sized mufflers where the cats were which will not rob anything and a small custom U baffled muffler that is where the third cat was.
