The last times on my car were run by the previous owner in Indiana. He was running 13.6@102mph on street tires. I am curious what kinda time you think I can pick up going to 3.73's from my 3.42's and also from 275/35/18's to 255/60/16 MT ET Streets.

I am just curious as to what you more seasoned racers think the gain would be. I have the stock stall, and am in Montgomery, AL. I am thinking the lower elevation, better gears, and slicks should get me pretty close to the 12's.

2 tenths? Im not looking for anything solid just an educated guess.

 

i dn it matters on the driver u might get the same worse or better...

 

Thank you for your reply. I know times will greatly vary between drivers.

I was looking more for experience. Things like..."when I switched to 3.73's it helped me pick up some much time." or "When I went from my street tires to ET Streets I picked up an extra so and so."

I know it is just hypothetical, and perhaps I should have worded things differently in the thread title. "How much ET did you gain when adding gears, or slicks."
