While selling VP at the track

[aafc]

I work for VP racing fuels at Orlando Speed World. So I took my Zr-1 to the
track to make a few runs while i sold racing fuel.
I have rpl the fx shocks with qa1's removed controller so no codes come up.
Adjust fronts to 0 clicks and rears to 4 clicks 26 lbs in rear tires (M/T).
I also had the convertor rebuilt . I now leave at 2200 to 2400 rpm .
The runs are as follows:
#1. 60 ft 1.742
1/8 7.636 @ 94.99 mph
1/4 11.902 @ 115.10 mph
hum 78% temp 85 deg.
AT 11:20 a.m.

#2. 60 ft 1.707
1/8 7.604 @ 92.96 mph
1/4 11.858 @ 114.46 mph
hum 70% temp 88 deg

last pass
60 ft 1.672
1/8 7.558 @ 92.99
1/4 11.825 @ 114.91
hum 62% temp 89 deg

I had a good day did not break anything and sold fuel to the other
racers. I wonder if my times are close to the FBI groups this Sunday.
Thanks again Pete for the help with my auto install on my ZR-1. (2004)

Great times, I'm sorry but I cant remember, does your 80e have the stock 2.48:1 1st gear, or the aftermarket 2.75 or 3.0:1 1st gear?

[XfireZ51]

Your 60' is excellent.

[aafc]

Thanks,
The transmission gears are 1st 2.75, 2nd 1.57 3rd 1.1 4th .75.
rear end are 3.73. also the converter was redone to leave at 2200 to
2400 rpm.

Thanks for the reply John, and yes XforeZ51 is right, your 60' is excellent, you're making many a car owner jealous.

Great times. I've been trying to get in the elevens with my stock motor car for a long time.
That quick 60ft. Time on the last run was obviously the reason for the great e.t.
There are few, if any, stock motor ZR-1's that can do 60ft. In the 1.60's.
What tires are you running?

Well since then i Rpl the M/T 315-35-17 drag radial with a new set of M/T
315-35-17 S/S tires. On Jan 8,2017 ran my best times. Track well prepped
air temp 43-53 deg sun out, all the cars were running there best times.
Made two runs
1st pass at 10:30 am
60 ft 1.642
1/8 7.391
mph 94.86
1/4 11.541
mph 116.93

2nd pass at 3:30 pm
60 ft 1.650
1/8 7.390
mph 94.71
1/4 11.542
mph 118.45
So new tires, killer air and well prepped track does wonders.And LT5's
love good cold air.

Sea level helps too.

Wow, very strong. That cold air really makes the LT5 come alive. It's 25degF. Cooler than I was working with. At least 10-15hp (IMHO).
The auto helps pull a great 60ft, and you're in the MID ElEVENS !

Now you've got to start pulling weight out of there, and go hunting for Pete.
Thumbs up!
