1/8 mile times
 

In general what 1/8 mile time relates to a 12.8-13.0 1/4 mile time. I know there are many factors involved but just want to know a range to see if I am even close to what the car ran before(by someone else) this weekend. Best to launch at 2-3000 on street tires?

I know Demps ran a 12.8 last year in his Blue car. Maybe he has the timeslip still.

I found a slip from Beach Bend in 2003 (84 deg, 100% humidity, 30.31 alt):

1/8 8.835 8.587
mph 85.13 90.92
1/4 13.362 12.919
mph 110.47 111.47

It ended up being a 1000 foot track, first time at the track for me, best I could do was 11.3 at 95 mph, 87 degrees, after 1 and 1/2 hour drive, no cooling down. Anybody have 1000 foot times and 1/4 times so I can compare, maybe this equals low 13 second run? I launced at 2500-3000 with some wheelspin be not excessive.
Aurora didn't you have a chart that has rpm and speed relation? Anyone have distance and rpm relation with stock gears?

Re: 1/8 mile times
 

Just ran Saturday, times as follows. I was at Firebird Raceway in Emmett, Id. Track elevation 2700, density altitude somewhere around 3500 ft. My 60 ft times last year were in the 2.1 range, so I have an issue(s) to fix. I added a Haibeck chip and Flowmaster Cat Back over the winter. Noticeable power difference and lots of wheelspin.

60 FT 2.39
330 FT 6.01
660 FT 8.878 @ 85.82
1000 FT 11.331
1/4 13.381 @ 110.19

Re: 1/8 mile times
 

My times are very very similiar, will post the exact numbers tonight. Also have DRM chip and Flowmaster. What tires and what was the air temp?

Re: 1/8 mile times
 

I have the Goodyear GS-D3's in the rear and I run 20 lbs of air in them. You can drive the car home, I live 20 miles from the track, or to a gas station to fill them.

Track El is 2700, If I had to guess I would say the DA was around 3500 or so. Air temp was about 60d with overhanging clouds.

First time at track but let me have it, 87 degrees, last(best) of 6 hot laps, no tire pressure adjustment, forgot to put suspension in sport mode.
Launching at 2500-3000, new Vredesteins, shifting at 6500-7000
