Went to the strip last weekend had some good runs had some bad runs but had a great time as usual. My question revolves around my times I lost around a mph and almost 3/10 in the 1/8. I'm definitely not even that good of a driver but I wasn't driving bad that night I actually pulled a2.1 60-foot time on 225 all seasons and was still two tenths of a second off. I don't think conditions were very good that I was like 77 degrees and very very humid. and speaking of tires since the last time I've been to the track I switch to a set of 225 by 45 tires verses the 235 by 40 that I had been running although I wouldn't think that little of a change would affect my times that much. the car seems to be in good repair but this makes me wonder if its hurting.I had the plugs out five thousand miles ago they look great air filters fresh oil is clean Mobil 1 trans oil looked great about 5k ago also. I don't know guys y'all got any ideas where those few 10ths went?

 

u went to a taller tire, and skinnier. also humidity doesn't help. those two things should not lead to a .3 loss though I don't think.

 

See that's what I'm thinking even with the skinnier tire I still ran one of my best 60 foot times

 

Bumpski pulled a 3v gt stang after 80 mph from a dig last night so I don't think its running too bad

 

Humidity can kill times, as well as heat. Any idea what the calculated Da was between this trip and your last?

 

Unfortunately not I'm running a dinky little track out East Texas (cedar creek)so the information is not provided on site
