Dirt to Ice times.

	What do sleds run from dirt to ice? I'm sure few have done it since dirt is 500' and ice is 660'. Would a sled that runs a 4.70 on dirt run high 4.40's in 500' on good ice in good cold air for example?

	3 10ths in 500ft sounds like a fair # depending on everything.Now if we can just get ice this winter!

	I would be suprised if there would be more then 1 tenth difference from Ice to Dirt . 2007 Haydays Prostock 1000, 2006 Haydays Prostock 1000, Open Mod 1000, FacMod-2 Champ, 2006 Prostock 1000 Michigan Cup Champion , Prostock 1000 World Record Holder 4.33 e.t. @115mph For same Results call Iantomasi Track & Trail

Re: Dirt to Ice times.

	Really? Better traction, freer rolling, and WAY more HP? That is why I thought 2+ tenths. Somebody has to know. The math alone suggests more than a tenth.

60ft times can be equal on the grass at many or most tracks , hp is the biggest factor , I know in the fall we can run 2 to 3 mph faster and just under 1/10 faster when the air gets good !
