1/4 times at an elevation of 4000ft

[JimT 99RT]

Has anyone run at their car at the Fallon, NV Top Gun Raceway Drag Strip? The elevation is at about 4000ft. Any idea about what I should expect for 1/4 mile times for my 1999 RT/10 with Michelin’s, Smooth tubes, and a Borla Cat back exhaust at 4000ft.

I found this link from NHRA.

Altitude correction

Reason why I found your post interesting was that I'm at 3800 feet.

Last I checked that resulted in about a 5-10% loss in power from sea level.

I run at RMR Raceway in SLC and the elevation is 4500 ft. I had a 97 GTS w/VEC1,K&N's, and no CATs and the best I did was a 12.49 @115mph. When I had just the K&N's the best I got was a 12.79. There was alot of stock vipers in the low 13's. Good luck

So, my 12.85 @ 114 here in Colorado at 5000' adjusts to 12.05 @ 121.5 at sea level based on the NHRA chart. Sounds ok to me for my 97 with headers, catless back, 3.54 vec-1. cones, etc. There are probably other variables though.
