Stock ZR1 on Drs


As stated in the title this is a stock ZR1 on drs running in the mid 10s. I had no idea these things could move like this.

Very impressive… The car also had the driver mod for sure.

Not just the ZR1s-

I can see daylight under those front wheels.

notes on the run from corvetteforum.com-

Some interesting things to note.

  1. Launch rpm = 4373, 100% throttle, full boost of 8.2 psi (calculated as the scanned map of 22.9 psi - 14.71 baro (per dragtimes, @ 3 pm, 54 degrees, 44% humidity, 29.95 baro, (29.95 inches of mercury = 14.71 psi), = (204) DA). I’m assuming on these blower calcs as I’m a N/A guy…I look for .99-100 kpa and know my filter’s not plugged and I’m good.

  2. Interestingly, the car was revving up to 5357 under about 1/2 throttle, then FARTPIPE floored it, the RPM’s went down to 4307, boost was building to max of 8.2 during that time…up to 4373 as the car spun just a smigen at launch (FARTPIPE compensated by reducing throttle 5% for .130 of a second), then bogged down to 3424 during the launch sequence (all at 100% throttle). Not sure why the RPM’s went down when he floored it, clutch in, from where it was at 1/2 throttle…must be some sort of torque management kicking in. My car doesn’t do that.

Some data:

0-60 time = 2.195 seconds…though if his DR’s are shorter than stock that time is a little off…still…blazing fast…assuming they are short, even using 0-65 mph it’s 2.455…handily beating the Veyron.

60-130 time = 6.165 seconds.

1-2 shift time, .195 seconds, 6,564 rpm.
2-3 shift time, .260 seconds, 6,621 rpm.
3-4 shift time, .195 seconds, 6,813 rpm. I wonder if FARTPIPE went clutch in before letting off the gas on 3-4, as you can see the rpm flare up to 6,922 when he was off the gas.

It appears the scanner only reads time in .065 increments…3x.065=.195 so the shifts were likely between .130 seconds and .195 seconds, but below .195 except for the 2-3.

FARTPIPE got about 13 mph wheel spin on the 1-2 shift, 8 mph on the 2-3 shift, and 10 mph on the 3-4. Some ET left on the table there, but I couldn’t find any other ET left on the table.

Car was running about 26 degrees timing, IAT at the start of the run was 75, going down to 63 degrees in 4th gear through the end of the run. I’m not familiar if that’s the pre-blower IAT or the IAT after compression on the pid that was scanned. My .cfg wouldn’t read the knock sensor for some reason but based on the commanded timing line I don’t think it had any knock. Interesting that this blown car takes more timing than my N/A car.

FARTPIPE ran it to 6400 in 4th…145 mph…in 10.65 seconds. Feels good to go that fast. I won’t type how long it took my car to go 145.

Overall, one of the cleanest runs I’ve ever reviewed.

Hats off to you FARTPIPE. You drove that car yesterday.

Awesome!

Badass…

Stooooooooooooooooooopid fast.
