If it was downhill I'd be trapping like 120 LOL. I really think it's just the weather. The colder it gets here the higher I trap.

This track yes ? Skip to 1.44 looks pretty downhill to me . Might explain it as my local track rises 6.5 ft start to finish. Must be some reason you are pulling more mph in the second 1/8th

I've trapped 110 at another local track. I'm sure both aren't downhill lol.

the track isn't downhill.

all tracks I've been to have a rise at the end to promote braking/slowing of the cars

Sure looks downhill in the video, the tracks over here are slightly uphill as they are ex-WW2 runways, they usually slope downhill in the shutdown so the opposite really.

They are great times for sure, just trying to understand why a stock car can pick up 25-26mph in the second half of the track when my car can only manage 20-22mph. But a google search (high trap speed captitol raceway ) found other drivers having high terminal speeds also

If you look at the drag times tables those terminal speeds are very high compared to everyone else , cant help thinking it must be environmental , or perhaps the air is just really good

it's all based on the DA (density altitude) and Maryland tracks are good places for good times/traps. well DA and track conditions, track prep, etc.. but the air/weather are big factors

capitol is only 40-45 ft above sea level so that track with good cool air will run good.

same with MIR in Maryland is only 80ft above and I know GT-R guys by me go down there to set PB's

Granted but if it was all DA then it would run just as good on the first 1/8th ?
