Say what you like. I have no illusions.
At my density altitude on that day (4200 foot air), my ET corrects to 12.65 @ 111 mph.
I don't blame traction, I run 17" street tires at the track, and won't be putting slicks on anytime soon.
I'm also running 8.4:1 compression with a small cam, with 1 3/4" longtubes. Very bad N/A combo. Very good blower combo.
I am looking to go above 125 mph in the 1/4 this year at altitude, which isn't easy no matter what size your engine is.
Considering a brand new 405 horse ZO6 went 13.27 @ 107 mph on the same day I was at the track, I don't feel my times are all that bad. I just wish I had the chance to line him up once
Also, a Procharged 2001 GT went 13.48 @ 110 mph the same day I was there. He had the extra oomph from that intercooler, but it didn't matter much on the launch pad
If you think 2400 feet doesn't make a difference, you obviously haven't tried it, let alone on a day with lousy air.
