GRM Challenge Miata - Dyno Results
After taking 3/47 or so at the challenge, I decided to finally dyno the car. I'm quite happy with the numbers, really. 187RWHP and 168.2 ft/lb. Not bad for a car that is at a current build cost of a mere $1975 (including the cost of the car) with about an hour's worth of street tuning. Did I mention that she's super fun to drive? There is definately a lot of room for improvement, though. There is still a lot of needed tuning and the turbocharger is quite undersized. However, the low end torque curve is pretty bitchin'.

My bad, I should have posted in the Dyno results forum. Please feel free to move it.
The paint is left over aircraft paint that was headed for the garbage. A friend works for PPG Aerospace. The gray is left over from one of BMW's corporate jets.
The turbo is an IHI VJ14 hotside and cartridge with T-Bird VC30 compressor. It spools fairly quick and is currently boosting to 15PSI, but it doesn't have a large flow volume.
A few additional details are as follows:
*SSAutochrome Knock-off GReddy Turbo Manifold
*Homebrew Manifold to Turbo Adaptor Plate
*Modified Volvo 740 Intercooler
*Homebrew Intercooler Piping
*Volvo 740 Radiator and Overflow Tank
*1987 Mazda 626 Thermostat Housing
*Mercury Capri XR2 Injectors
*Homebrew Downpipe with Divorced Waste Gate
*Megasquirt I w/ V3.0 board - full standalone.

Part of the rules allow selling parts off the car equal to the amount paid for the car. Buy a $2k corvette, sell enough parts off it to equal $2k and you have a whole new budget to spend. Not saying it's easy, i'm sure it's tough but they can recoupe costs that way in order to sink more cash into the vehicles.
