Supercharger 70 mm Pulley Upgrade for MP62 by Track Dog Racing 1994-2005
1994-2005 MP62 Supercharged
There is a myth that superchargers can't use Air-to-Air intercoolers since they can't offset pressure losses due to piping and intercooler volume. However, superchargers have the advantage of providing instant boost and increase boost as the RPM increases. Pressure drop is negligible and the substantial cooling benefit of an Air-to-Air intercooler offsets any losses in boost levels by allowing your supercharger to work more efficiently. With cooler, denser intake air, timing retarding is reduced, producing even more horsepower. Since forced induction by nature produces extra heat, efficient cooling is critical to ensure maximum performance.
Some features and benefits:
Highest Quality Components
All-Aluminum core - 16"" W x 8"" H x 3"" D
304 Stainless Steel Piping - Brushed Finish
Powder-Coated Aluminum Radiator Cover
Three-ply silicon hoses
Typical efficiency about 80-85%†
Designed for the least amount of pressure drop
Plastic panels that enlarge the radiator shroud area
Cooler air reduces chances of detonation
More timing (less retard) can be added, producing more horsepower
More boost can be safely added
† Efficiency based on (Air exiting the compressor minus air exiting the intercooler) divided by (Air exiting the compressor minus ambient air). Example of Air-to-Air: 300F - 115F / 300F - 80F = .84 = 84% efficiency. Example of W/A: 250F - 180F / 250F - 80F = .41 = 41% efficiency.
