Had a couple run-in's daily'in the GXP recently instead of the Honda...because it has no AC.
Ran at least an intake/exhaust 04+ supercharged car from a 60~, was actually pretty decent...GXP needs much better gearing...so lame having one gear go a billion MPH, had that thing by a couple cars by 120~.
Ran a first generation Charger 5.7...sounded like doodoo, probably straight piped, bigger wheels, all murdered out, did a dig. By 80~ had a solid car.
Was however blown completely off the road by a Audi RS5...raced for S&G's, those things sound amazing. Do want.
The end.
Boring.
This car is slow for a V8.
