From my laps, over the last few meetings at Puke & Hampton Downs, the top HMC cars are doing 1:15's and the U3L HSC are doing 1:19 / 1:20's You can throw a blanket over me, Jonh Dennehy, Hillsy and John Sampson, depends on the day who is quicker, but we are all usually within a second of each other. A couple of the HMC cars are in the 1:13's at HD. So I'm guessing that's similar to back in the day when I watched these races as a 5 -6 yr old at Puke on the long back straight. May have been a bigger difference then due to the HMC cars running off down the long straight. Wet conditions it's almost a level playing field, probably a bit in favour of the HSC cars.
