Just weighed the car again. The previous weight of 2940 was with the old wing, no AC compressor and no AC condenser on the rear wing. The previous wing was metal with a rubber lip and a different radiator with dual fans.
The weight today is 2920 and I have added the compressor and rear condenser. The rear wing is a Toy-Jet wing with his radiator and setup. The newer wing is fiberglass and the lip is also fiberglass, although it looks like rubber because of the paint. After taking the car to the tuner, lowering the fan on/off temp, changing the fuel mix and timing, I can not get the car to go above 184F. Same time last year, didn't matter if it were cold outside or not. If I brought the rpm's up above 3500, the coolant would get well above 220 after a few miles of driving. We shall see what the summer brings.
So far, I have lived up to what I set out to do. Swap motors but not cut up my car. It is pretty much stock with an obvious LS1 in the rear but everything else remains. AC is working nice. Summer will tell how nice. Getting ready to deal with the heating. A guy down in Oklahoma is building me a heater box/core for the rear, under the rear seat with a Spal fan and ports into the original heater ducts. We shall see how well it works. Getting cold up here in NY.
