If your car is set up as a proper drag car, you will run the quarter in sometimes even a second faster, depends a lot on your skills. If you have a standard car, it would be wiser to buy either a gearbox, driveshafts or clutch beforehand though, as these are the most likely three items to go with the amount of grip produced. But in all honesty dont bother, just lower the pressure of your good and soft road tyres by about 8-10psi and should be good enough.
