How about some help on this one.

A Vortech SQ-Trim supercharger was installed in my '93 GT about a year ago. I've been very happy with the results except for the fact the car like to overheat in city driving. I had the 7year old head gaskets replaced shortly after the Vortech was installed. So the gaskets are not the issue. I also don't believe that the temperature guage is the issue either. The overheating is obvious just by lifting the hood... HOT!

On the freeway, the temperture where it should be- between 1/4 and the 1/2 way point. When i come off the freeway and start city driving... up goes the temperature. Then back on the freeway, the temperature cools down.

I began with the FMS aluminum radiator and a slimline Flexalite fan. I then bought a Ramcharger dual-fan but the thing does NOT fit. I don't know how people with supercharged Mustangs can make the Ramcharger fit when clearance is slim. Ok.. I then buy a Fluidyne radiator... one of the best. The Ramcharger fan still did not fit even after "modifying" it. There goes $140!!! So back goes the Flexalite which is about the only type of fan that will fit.

Even with the new Fluidyne radiator and the Flexalite fan, the damn car STILL overheats in city driving!!! You can feel the heat from the engine when lifting the hood.

10% coolant- 90% water+ Redline WaterWetter ; 20% coolant - 80% water+ Redline WaterWetter; Mr Gasket 180 degree thermostat; it doesn't matter! The engine overheats! WHY! WHY!

I was thinking of the Vortech Aftercooler but i'm sure that other Vortech supercharged Mustangs are running cool without it.

What else do i need to do to get Vortech'ed Mustang to run cool in city driving??? What's the secret? I'm sick and tired of this cooling issue and i want resolution once and for all!

Suggestions!! Please!
