Rayzor Twin Turbo. Put some twin turbo physics together and used the rayzor car to test what do you think its correct with the 4 wheel drive.? www.dropbox.com/s/yn6t3f52vm64ur1/Rayzor_Turbo.rfmod
The throttle is an on/off switch and all sounds are in the cockpit with you. Keep at it, this could be a fun car. It also needs some adjustability options when you choose the higher kits. Different spring rates, dampers, gear ratios etc.
I presume you cannot see it to use, you have to select all cars / tracks. Should show up, not tried this one myself. Have no idea what a rayzor is?
Sorry i just couldn't find the car in the car list because it didn't have a picture but it's good now
