diff ratio, much of a difference?

I'm actually quite suprised how nicely it hooks up. An old car of mine I used to race was terrible to launch. It took.me a long time to.learn to balance what little traction it had. Then when I fitted drag radials I broke an axle.before I could unlearn that to suit the improved grip.
Given this car has a lot more power the tyres really seem to hold their own.
