Cooler intake charge is NEVER bad.

I am of the opinion that if you can keep the stock IC cool that it is ultimately the most efficient choice. There is virtually no extra plumbing to create turbo lag and the 87-88 TC's don't lend themselves well to front mount IC's because of no grill area. You would have to hang it down low or fashion some sort of scoop to really force the air through it. I am working on a forced air IC which can be found in the tech article section. I have built Jeff Korn's temperature sensing unit and am having a baffle welded to my IC this week. Just my two cents worth.

I agree that if you can get away with keeping the stock IC nice and cool then it can function pretty well, but the core is also too small to really push air through efficiently.

And as for extra tubing creating turbo lag, I am currently running a Grand National IC between the engine and rad and haven't experienced any difference in boost response. But I will say that it pulls much stronger, and "feels" like it's breathing a lot better at high boost/high rpm loads.

A bigger core is necessary sooner or later, unless you keep things relatively mild.

natmac3 what mods did you do to get the GN intercoolerto fit did you have to use a single fan instead of the dual factory set up

Slim radiator fan, not sure what brand.
Custom-bent aluminized tubing (I'll take pix)
Rerouted lower radiator hose (again, pix)
Various hoses and clamps (in the pix too)

Let me go snap some pix and I'll be right back!

Last two.

If you have any questions- please ask, I'll be happy to help. I also think it's good to have some pix of this install posted because when I was searching I could only find 1 or 2 people with pix (thanx you guys [Image: biggrin.gif]) and that took a long while.

Nice... Where did you get that piping? I'm probably going to set my unit up like that.

How much did that set you back?

The aluminized exhaust pipes were a custom bend job done by a friend to match a mock-up I had done with other junk pipes I had lying around.

The total cost, including the fan, was less than $200.

Grand National IC ~$100
Slim Radiator Fan ~ $40
Hoses and Clamps ~ $20
Pipes done by a friend ~ priceless ($0)

I realize not everyone has the "hook-up", but with a little hunting a similar setup can be had for less than $250, if not the same price, and maybe even less.
