Possible new car......

I just tried this…launching at 3k, 3500k, and 4k and all the same thing happened…It bogged down to about 2k. I tried “slipping” the clutch and dumping it. Both were the same outcome. My clutch is a bitch I hate it. When you try to “slip it” it starts vibrating, hopping grabbing harder etc. Its a bitch to slip.
