There was a thread on here years ago but the photos are gone as are most of the photos in the site. My set-up is with AC but both IC pipes end up running behind and up over the radiator. Seems like poor engineering to me and would like to correct it. It seems the heat coming off the fans is really defeating the purpose. The placement of the piping only leaves about 2" between the piping and rad which leaves me with dual fans that are undersized and not drawing enough air though the radiator. Wonder if there are photos of set-ups with AC and with the nose off?

- My setup is on there but I'm not running an intercooler atm.

Thanks. there were a couple in the old thread I wanted to look at. Can't remember who they were. I think Neil86T was one.

I once had an 86 Turbo with the Spearco 2-221 Intercooler Kit. That was the only kit I knew that cleared the A/C with no trouble other than custom intercooler piping. You could try Bell Intercoolers which custom made an IC for Jason, but be prepared to shell out a lot of money. I once called them and Turbonetics about making a custom IC kit similar to the Spearco one and they wanted over $1,000. With that said, I usually don't bother with an intercooler on 84-86 because you can run 10 psi on premium fuel due to the low compression ratio. Of course, it'd be nice NOT to have to put premium in it and save some pennies at the pump. BUT THEN AGAIN, I don't drive the car all that often so what does it matter? OH here I am rambling on again and most likely nobody fricken cares. [archived image: tongue.png]

Here's my setup which kept the AC.

Is there any advantage to routing to the side of the radiator vs going over the top?

I would think a good bit of efficiency of the system would be lost. A fabricator intimated the intercooler to intake would be the primary concern and shielding the air intake from engine heat.

There's simply more room staying low and going to the side. The hood to belt space becomes a problem when going high. The first version on mine was set up that way and I had problems with it pushing down onto the belt.

I used 2 1/4", I believe, piping. There was minor interference with the hood. I dimpled the support bracing of the hood where there was contact. Probably 3/8" diameter dimple. That gave me about 1/4" clearance over the belt.
