do u drive an auto? seemed a bit slower than it should be. i might be wrong tho.
what was the other car next to you?

 

^^he has a short shifter so its MT.

high 15's though...ouch.

 

Notice the tracks elevation at 6400 feet. His actual time is probably around mid 14's.

 

That took forever to get to the end! Ill tell you it is very cool that you posted that. Most people havent a good understanding of what elevation does to your car. I race at a track at 4000 ft and I get bombareded by people when I post a time from that track. They always tell me how slow it was compared to thier time.

 

so the higher the elevation the slower your ET?

 

Well, yeah.

A car doing high 13 seconds near sea level on a well prepped track would do around low 15's on a track with 6400 ft elevation, assuming its as prepped as the other track.

IMO, a track should never be built at such high elevations.

.

 

Yeah elevation has a huge impact on how much air your car can get in and the power goes down.

Example:
I live in Phoenix (~1100ft) and go to Prescott (~5300ft) all the time. When I go up there and don't change my boost controller I loose about 3-4psi of boost. That's a good 50-60hp on my car. We did a dyno at 5psi and at 8psi and I made 55whp more at 8psi. Those numbers won't be as dramatic for N/A cars but you still loose a lot. The good news is that everyone looses power, not just you.

 

Yes i'm driving 6MT. The other car was Grand Prix SuperCharged + chipped

 

Can't really tell from the video but what was your 60' you eased off the clutch real well.

There should be an equation somewhere for Air density vs elevation and you can factor that into your Air/Fuel...more time to get the same amount of air you would at sea-level, the slower you are on the track.

good thing the track I go to is only 903ft

 

They do have a thing called Density Altitude calculators to correct your times for sea level.

out of range there..I guess 903 feet is not that significant.

 

This is the calculator I use:

not bad
