1/4 mile times wont tell you anything about Power just grip off the line & weight. The ET will give a better indication of Power. The good old fashioned Daddy Thrash at Brunters is the best bet. You can have a standing mile race against your rival & record all the times to get there. The guy with the fastest speed will have the most Power with no bullshit attached. Get 1-PD to organise it. Would love to see if we can add to the 15 Cossies past 180mph you need a genuine 490bhp to do that but past years proved very very few could muster that.
Ive retired from such events but would love to watch or help to organise.
