Title: Doghouse Shroud
Post by: josh on June 23, 2005, 01:28:06 PM: I'm not running heat and I want to ditch the outlet ducts on my shroud for a cleaner look. Have a good original shroud and i'm wondering if instead of buying an aftermarket one w/o outlets (heard bad things about cheapies cooking motors) can I chop the ducts off mine and skin it in sheet metal. Will this screw up the airflow direction inside??? Anyone done this?

Thanks Josh.

Post by: 65type1 on June 23, 2005, 01:51:50 PM: There are 3 or 4 spot welds that hold the outlets in place. I had to grind a couple of high spots on the shroud it's self where the metal is rolled up a bit. Made templates to fit into the holes and welded them in.

I haven't had any heating issues with my 1915 and i run 9.5:1

Post by: Trevor P on June 24, 2005, 03:43:24 PM: The Thing shrouds are fairly hard to find, and are usually not cheap when they turn up. I have one on my 1835 engine. I find it to cool great, and has a way cleaner look. I have heard that the inside around the heater outlets is slightly different between the type 181 and regular DH shrouds... I believe I saw this posted somewhere on STF. Can't confirm this forsure however.

Prices are usually around $200 for one in decent condition.

Hey Rustybus, is your industrial shroud a doghouse style?

Post by: Hansk on June 25, 2005, 11:28:37 AM: Hey Rusty

On the back , little \"dog house\" for oil cooler sticking out of the back.

Just flat on the back =.......not a \" dog house\" style shroud

Post by: rustybus on June 25, 2005, 11:39:35 AM: Nope there is oil cooler cut out. I guess this would make them a 40 horse?

Do you mean \"no\" oil cooler cut out? Flat on the back?
If so then it's probably a non fresh air 40 hp shroud.
It's the later dog house shroud from 1600 dual ports that
everyone wants

Post by: josh on June 26, 2005, 09:40:46 PM: I think I'll just play around with the one I have, I want the super clean look without all the notches and coil mounting holes, yada yada. Gonna hand it over to a sheet metal buddy to skim the whole front/ top of it. I was thinking about the airflow with and without the outlets, would without direct more air over the cylinders=better cooling???

Post by: Hansk on June 26, 2005, 11:09:55 PM: I read this somewhere before, once you have the outlets off , look down inside the hole. You should see that the air flow is blocked from going to the heads forcing it out the heater outlets. Cut a hole so that the air can blow down on the heads and not just be totaly blocked once you fill the outlets. Apparently the thing shroud has something like this. Maybe Glenn can confirm this?

Post by: Glenn on June 27, 2005, 02:58:41 AM: I've never taken a Thing shroud apart, but i've also heard that the internal vanes are different. And simply plugging or even removing the fresh air outlets cause internal turbulance and cooling is not a good at a real 73 Type 181.
