Now that I can actually remotely entertain the notion that I may be able to start this thing in a month, This new question has started to crowd into my head.

All you have to do is look at some of the dash pics from the drivers' perspective, and you'll see that turbo poking up well above the cowl/fender line. It has always been a plan to accommodate that by adding a blister to the hood where that thing sits, but I wanted to go a step further, and add cooling slots/fins/vanes to the back of the blister to allow scalding air to get out there.

The obvious side effect of that would be that cold water both from washing, and rain will be able to run down onto the hot side/turbine housing directly.

I'm thinking that's a bad thing.

That "blister will probably stand proud of the hoodline about 1.5-2". As stated above, I was thinking I'd add a set of stepped slots at the back of the blister, (each step above covers the one below it, you wouldn't be able to directly see into the hood by looking straight down.) and these steps would open a hole that would be right on top of the turbine housing.

So,...thoughts?

Could you Fab up a cooling duct to go to it like a brake cooling duct used on some cars?...that way it doesnt allow water directly on it by does allow outside air to cool it?....just an idea....lol

Also another idea....if you look at the older trans Am there hood scoops you can open but they have a ridge with a drain tube attached so any water it is like a Gutter on a house just goes down the tube....

No room for fancy contraptions under there. (Have you looked at the engine compartment pics?, that thing is so full, I'd have a problem finding a place for the drain tube itself, much less an entire catch tray.

Do you tend to wash your car in your driveway or at a car wash? Do you plan to drive the car in the rain on a regular occurrence? My guess is you would be fine, so long as you just start the car, back it out for a wash and turn it off before the hot side gets hot. And with your louver idea, I doubt very much rain water would get in in the small number of storms you find yourself caught in.

Cracked parts suck! I am not sure I picture your set up exactly but water on hot exhaust stuff is just asking for a new parts requisition.

Ok, if you decide to wash the car via pressurized hose, put a bag or blanket over your engine/turbo. As far as design, wow us. Get some sleep after a couple of good drinks and imagine the thing. Otherwise, you will start talking about "symmetry" and a bunch of other female words not allowed as a moderator.

I'm not crazy about the turbine housing getting wet, being cast iron it will certainly rust. I suppose some sort of ceramic coating could be powder coated on the exhaust housing, not sure about the bearing assembly though. My vote is to put a heat blanket on that sucker and keep the hood closed up, not exposing the turbo to any amount of water.

Put a lot of water on red hot cast iron and you stand a good chance cracking it...
