Just wondering if anyone has dyno results of various stages of the mods of Turbocoupes? I just got my TCoupe last week and ordered a K&N for it yesterday, and hope to get the Gillis valve in the next little while, along with a 190lph Walbro.

Most of us test our cars at the track instead. A roundabout method of approximating the hp levels at different "stages" is to find a car that relatively matches your's in the 25 Fastest TC's list, and then entering the car's trap speed and estimated weight into one of those online horsepower calculators. Keep in mind those are VERY rough estimates and each car may not produce the same results with the same parts.
