I just bought a riveting setup & I have sheet aluminum.

In a few weeks or so, I'll try a cool air box fed from the tail inlet - with a very small open portion on the bottom in case water gets in the box. Not gonna be easy - it is tight in there!



Inlet temps are 14 degrees above ambient, so this ought to get inlets very close to ambient -

(Sorry for the temp thread hijack)

Guys, is this the stuff I should look at using for the IC shroud?

Thermotec Pipe Insulation

I think the "QUick Seal" product has the adhesive centre.

Make sure it is the stuff that is 'more rubber than foam' regarding the properties - it is more pliable than the cell foam stuff. Heat resistant is a must too. My opinion -

FWIW, the rubbery stuff tends to 'stick' on a warm IC and pull off the metal shrouding - just kinda be aware of this when you assemble and design your setup.

I haven't had any problems with the sticky stuff yet. That is the correct polyfoam Merv. What I did was to cut one piece about four inches too long and then spread the slit open and lightly stick it onto the top and side of the IC. Then cut another piece on a connecting side that is also too long. Since the pieces are round and not quite at a 90 angle you must eyeball the miter or corner cut. Cut one piece at a 45 degree end and then cut the adjoining piece and trial fit it to the other 45 deg. cut. Work your way around the IC and when you are done use some black weather strip glue on each corner and the put tape around the whole thing until it sets up. The original glue on the insulation is not meant to hold against metal so you will have to decide what type of glue to use. I used the same weather stripping glue. Now when you close the lid there is a tight seal with the IC and no air goes around the IC. Please note, this is not a concours mod. It works well and when it needs to be replaced due to damage or werar, it will cost you another $10! Not many P-car mods for that kind of money.

Thanks for the detailed explanation, Rudy.

I'm not a concours junky, so I don't care if it aint pretty. As long as it's functional, improves cooling efficiency and makes my engine more reliable, I'm happy

Is the rest of the tail blocked off - or nearly so?

I finally got around to taking some pictures of my intercooler shroud. The GT2 tail has a huge surface area, I am certain that no air was going through the intercooler. It was simply a heat sink sitting out in the air.

A very thin sheet of stainless was used with a hole cut in it to fit the intercooler core. Foam rubber was glued to the S/S and formed to fit the intercooler. The back end of the square hole was left open to allow air to be pulled in toward the air filter and to not choke off the fan.

The results were no less than spectacular. I picked up a BUNCH of power, lost a LOT of lag, and raised the engine temp from 150F to 190F. The engine actually runs better. Too much cold air was engulfing the engine compartment and cooling the WUR and sensors causing the fuel pressure to be less than optimal.

Excellent! Very similar to mine. Great use of air guidance to your filter.
Believe Brian's (cold weather, at a minimum) results - he is an experienced WUR 'fiddler'

Not quite clear in photo-- if you look at front of i/c ypu can see extended edge that runs around top of i/c with dressing strip running around the edge-- this is touch fit to vents in grill to outside the engine bay. Purpose was to exclude engine bay hot air and was definately effective.
