Been modifying my car over the years in the garage and haved one more than most. Had a ProCharger P1at first, and now a D1. Have used a 3.0 pulley, a 3.2 and a 2.4, maxing out at 18 psi of boost. Have used a ProCharger intercooler and now use a 31 horizontal flow intercooler with 3 entry and 3 exit. Started with ProCharger 3 steel intake piping, but have switched to aluminum. Have gone from a Focus pump with a BAP, to twin Cobra pumps, to twin GT-40 pumps, toa return style fuel system using a MagnaFuel pump and regulator. Didn't like the pump cavitation at tankfull and the constant smell of fuel vapors. Have gone back to returnless and twin GT-40 pumps. Have gone from 42 lb injectors, to 50s, then60s, then 80s, and now 98s. Have gone from a stock upper intake, to a ported lower and upper, to a highly modified cut-n-weld upper with expanded height, rear, and L & R plenums. From there, went with a Freestar 6 into 12holes lower and a custom upper. Have aSnow Meth/water injection system and also Nitrous. Went from a 70mm throttle body, to a bored72mm TB to now an 80 mm TB. Along the way, learned to tune the car mainly due to all the changes. Still use A/C, power steering, heater, and stereo. It's mainly a street weekend car. When tripling the whp or more, lots of things on any car will not be engineered to take on the extra power. It takes a lot of add-on parts and customparts to make it happen and keep the motor, transmission, rearend, driveshaft,etc. from blowing up. It is very frustrating making and testing mods to keep the car safe and still pass an annual emissions test. So far, so good. Lots of work and plenty of $$$$ spent along the way. Have learned a lot and am willing to help others minimize some of the expense by buying the right parts for the intended application. So now, off to bigger and better.
