heres a 35 mph - 145 mph at about 8.5psi.
LOL my boost controller display falls out on one of the shifts cause i hadnt used any velcro or double sided tape to secure it yet since making that bracket for it.
sorry for the poor video quality, i took the video with the go pro suction cupped to my side window. i edited it ghetto with some freeware that i downloaded because i actually recorded an entire 20 minute beat down session with the car, but then figured i better not upload the entire thing if want to keep my car and drivers license.
if you recall from your own 370, the speedo digits are in 20 mph increments, so the starting point is roughly 35 and you can see i let off at about 145.. you have to play it full screen to really see anything. sorry.
you can see these cars are pretty quick with a little boost on the stock motor. but the speedo starts to move pretty slow by 100 and above... needs another 200hp or so to have the excitement it needs!
