Intercooler shroud mounting?

[Pronto]

Anyone come up with a better way to mount the shroud on a Precision slic? Those short sheet metal screws to me are hokey. I'ld almost like to drill and tap for longer machine screws. I was looking at an old Mease slic and the shroud he had was plastic or fiberglass and had no mounting holes. How did that stay in place? I almost wish it was made out of rubber and could be mounted to the frame and just press up to the intercooler to box it in. The scoop doesn't clear the frame enough as it sits now either. Guess the simplest fix is a front mount but has it's own set of issues.

I went to the store and got a nice set of stainless sheet-metal screws and a small stainless washer. Looks really clean, Ill go get a picture for you. I wouldn't want that thing flying off at speed, so I don't see any other way. Have to have it fastened somehow.. Maybe instead, attach it on the sides? That way it is not as noticeable from the top looking down.

Yes, I've done that. Nice ss wide pan head screws. The other day I noticed 2 down low missing. Must have backed themselves out and are now gone. I wish I remember what store I got the new screws from.

The Precision SLIC shroud directs most of the air flow through the bottom 25% of the core. The core is great (1.5 psi drop) and may be comparable to some earlier/smaller front mounts. I have done some work on the shroud to improve the air distribution through the core. The trouble maker is the clearance from the existing intercooler shroud to the rad fan shroud. Its shocking how fast people have gone on that intercooler. My shroud screws have not fallen out yet but it sounds like they will.

I would like to see how you modded the shroud to help distribute the air better. Been contemplating the scoop area for more clearance to the frame as well. I'ld love to have a hood scoop that directed air right down into the scoop, kind like a ram air scoop.

I would have to post a sketch. There is one simple thing which will help. Pop rivet a rolled piece of aluminum inside the very top corner (going across the scoop at the top) to channel whatever air is currently getting up there. This will reduce turbulence and increase the path that the air has to get into the intercooler. The scoop needs the welded corners (on top as the air enters) to be radiused and a well positioned splitter to direct some of the air flow up into the trough. The optimal position of the splitter/air foil is a tedious problem to solve either with CAE/ lab time with pito tubes and volometers. Sorry for the rambling.

we use hex head self tapping srews .. worked like a champ.

Dan, do you mean the type that have a groove up the threads? I think the holes are only 3/8" deep. If they went 1/2" there would be a lot more bite for them.
