I went to the strip last night and I did some upgrades this year and seem to loose time ?
Any ideas?
I put on
4 qa1 shocks (dialed to 0 for drag racing)
New bosh 3 injectors
new plugs
new wires
I went from my performnce chip to my stockchip
a Line lock (this was not my best idea its now a electric parking brake)
some how my best time was 14.9! last year I was around 14.5 with the egr causing detenation.
It felt like it was shifting into high gear way early. The trans fluid looks a little dark but not burnt, It did not feel like it was slipping.
I was told the track was very loose but i didnt really notice any tire spin,
Get out your best time slip from today and compare it to your best time slip from before... post both and I'll see if I can tell you whats going on.

Indeed incremental times, especially short time as well as trap speed is needed.
BTW, what were air temp, RH and pressure at each event? I have equations to normalize ET & trap speed for temp & baro.
What year Vette?
1985 Stock except for the mods above and i will dig out my old slips, It was cold friday like 60-65f
last year it was much hotter in the 80's if i recall

Vet racers please educate a newb
Stock standard should be 14.5 sec quarters, fit headers open the air filter cover for more airflow and fit an adjustable fuel pressure regulator and set to 45-50 psi. that will knock a second of your quarter mile time.
Unbolt your cat and put in a straight thru pipe for the track. Underdrive pulleys will also help. These two took my 85 from 14.0 to 13.6 (automatic with 3.07 gears).

No cat, and Open pipes @ the rear via electric Cut outs
I see a blueprint engine in my future I think she is pretty tired after 28 years it may be just time to replace the motor
