NPR Intercooler fitment

gottarollwithit · 07-04-2012, 09:12 PM

So i'm contemplating installing my NPR intercooler. My car is an 88' 740ti.

What do you guys do for mounting/securing the bottom part of the intercooler?

I want to keep the stock airbox setup. The thickness and width of the intercooler work fine, but it is a few inches too short. The bottom of the intercooler is a few inches away from the lower radiator support brackets. What do you guys do to mount the intercooler onto these brackets? Any of you guys fabricate a big rubber riser or bushing to fit into the brackets?

I saw Simon's NPR intercooler installation vid and he uses a piece of wood. I'm trying for a long term solution here and wood will eventually rot/compress/degrade. Any ideas?

Is that...styrofoam???
Doesn't that stuff compress a little bit and rub away with friction?

you could use rubber, pvc aluminum be creative!

I was going to use rubber, but where the heck do ya get a block of rubber that big! I figured i could carve a couple pieces of rubber to work as a big intercooler mount, but just couldn't find a big rubber block.

I considered and aluminum bracket, but that intercooler is probably going to jump/vibe/shake around and eventually the alu mount will gall and damage the intercooler.

I've actually had wood on the bottom of mine for.....counts....4 years or so? Never really had any issue thus far.

Worried about wood? Use pressure treated deck planks....think they are about 3/4 thick. Otherwise, fab some supports out of mild steel and weld/bolt them in.

Styrofoam works well. There is nearly no downward pressure; it's held by the pipe connectors. Still, I opted to build a sheet metal ledge.

Rubber lift pads cut to fit?

2fast242gt · 07-05-2012, 10:46 PM

Rubber wheel chocks cut them up. Be creative.

Cedar worked for me. Light and it doesn't rot.

I cut up used radiator hoses and stuffed them underneath, just added a little barrier so it wasn't metal on metal contact. Like others said the hoses/clamps held it in place.
