Different for every car but I like to start at 3800-4K. Right where it really picks up with room to wind out to 7K. Usually the race is nearly over before you even have to shift unless its close then you *might* see a bit of 3rd gear.dam no joke on tha weight reduction, yeah with some bolt ons, who know what you can pull off...i agree i hate tha low end, if we are to race from a roll, at what rpms is our prime what will give us tha edge?
Unless you're rolling below 30 I'd say grab 2nd, any slower and 1st gear is better providing you can perfectly shift since you only have a second or two of WOT in 1st before you redline. So you have to blip on the downshift to 1st so you dont eat the dash, hold the revs steady and wait for the signal, then immediately just floor it for fractions of a second and slam it right to second then hold until you're done or hit 3rd if you're racing faster than 80.
Thats with my stock 3.27s that your snake has too. Weight reduction or not thats how I'd do it.
