Hey Terry,
If you're absolutely STRAPPED for a guinea pig car (lol...yeah, right) I'll gladly test your twin TB setup! With all the SNOW and freakishly cold conditions right now in MI, I think you need a test subject in sunny Southern California!
- you know, with year round mid 70 degree weather, we have the ability to take it for for extended runs you know, to gather data, and stuff... :p
