Just to clarify, that difference in temperature won't affect your times that much if your talking about the difference in power. But if you are talking about how the track will affect the times from these temperatures then yes, it does make a difference but more like 2-3/10ths of a sec.

When you get really cold conditions the track cools down a LOT and then becomes very slippery. Your 60ft times will increase which in turn increases your ET. This is what happened at Compak Attak, so much so that they cancelled the remaining part of the event because the track cooled down so much that it was like an ice rink for the more powerful cars.

Essentially what the guys are saying is that there is no "one setup fits all conditions". You may have a good base setup that is fairly good for most situations but to optimise your ET's on a given day there will always be some adjustments to be made. Ask Yonas how many different tyre pressure and rpm settings on the launch control he may try at any one street meet. The only way to find out what works is to try things. Launch control settings and different methods of launch control is just one part of it.

Drag racing is not as easy as a lot of people make it out to be, especially in a FWD.
