Straight line speed is also a lot to do with the speed you get off the last proper corner before the straight. Too many people complain they get passed on the straight and need more speed without looking at the corner speed of the car that just passed them.
Back in the days when I could drive a Modified 12th car, I used to practice at the Chesterfield club. Andy Griffiths, multiple UK National Champion was also there. With a 6.5 motor in my car, Andy would lap me twice in an 8-minute heat driving a 10.5 motor. Guess who was faster down the straight!!
If you gave your Turnigy-powered car to Mark Stiles or Chris Ashton, they would be lapping you even if you were driving their car. The great thing about pan cars is that if you can drive you can win - and no amount of money spent on the best kit will allow you to beat the best drivers if you can't drive. Yes, a faster motor will get you a couple of tenths on the straight, but you will piss that up the wall by missing the first corner apex.
Get the Turnigy to the best speed you can by working through timing and ratios until you have it sorted. Check every adjustment against the clock, not the speed gun. If you are still not the fastest down the straight, try being fastest through the corners!
