    Various gt500 Throttles

    Does anyone happen to know how to get their hands on throttle body data for gt500s. I cant seem to find any eg whipple billet, vmp, monoblades, cobra twin jet, ect ect. There's plenty of information on everything but these why?

    You can make almost any "a-like" throttle body work. If it's a twin blade, you can make a 60mm work with a 65 or a 67.. I prefer running one closer to the twin 67. The mono blades are the same. I've ran all kinds of twin calibrations on a 67, I'm using my own calibration right now. I'm picky and I didn't like how my throttle angle predicted and throttle area histograms weren't following the same cells, so I made them follow the same cells and calibrated my own. To make these work you have to learn how to adjust the torque tables and calculate the inverse.

    This is the throttle body model for the twin 67. VMP sells the product with their name but the company that makes it is C-F-M Performance.

    This is the throttle body model for the SCJ monoblade.
