What ET to expect with a 116 MPH trap?
I have had the chance to run at the track once with slicks on my car so. This netted a 12.3@115 MPH - on a 2.0 60' time. The clutch (factory Valeo) was slipping BADLY - thus the 2.0 60' - the tires were NOT spinning.
Anyhow, Last night I went out again, and managed a 12.7@116 MPH on my DAILY driven street tires - 2.2 60' ft time. (Bridgestone Potenza RE-71's)
I am just curious as to what E.T.'s I could expect (realistically) out of a 116 MPH trap speed - once I get the clutch worked out and strap on the slicks again. I am "guesstimating" 11.8 - 11.9 with a fairly mild - solid launch.
If you need more details of my car - they can be found at www.nvmyz28.com
Running Spohn Torque Arm/Panhard/LCAs - stock suspension ontherwise - other then front springs. SLP Subframes. 3.73 gears, M6, 383 w/ 100 shot NX wet.
I plan on using either a Spec 3 Carbon clutch - or a Mcleod twin disk - and running on 16" ET Streets
Keep in mind I am running at ~4,600 (sometime the air is equal to ~5,200' !!! ) elevation in Utah
Thanks for any input.

If the car is geared to cross the finish line at or just after the red line in high gear (no OD), a 116 mph should be around 11.4 - 11.6.
When I had a 383 stroker and 3.27 gears I ran 117 mph at 11.9 but had lots more rpm left at the end. 3.90 gears would have been better so that I would have crossed the finish line at my red line.
Don't tune the car by watching your ET. Do changes to increase the MPH. A predicted ET from the MPH can change too much depending on many factors such as launch rpm, gearing, tire size, shift points.

116 mph should net...
... in the real world 11.6-11.7 ETs, depending on air and traction.
By the way... a real drag car is designed to go through the traps at at least the RPM shifted at, in your 1-1 ratio gear and LOCKED in 3rd gear if A4. When I ran 4.56 gears with 28" tall tires, I was real close at about 6300, locked.
116 is a good trap speed... so far it is my best also! Good Luck!

Hence no slippage or VERY little, just like a M6 car, plus I have the benefit of increased torque multiplication off of the line!

The only time Redbird was on a Mustang dyno, she only made UNDER 320 HP and TQ. Not that impressive!
If people would only learn to have their converters lock and gear properly, you can hang with a M6 on the top end. When my converter locks it's just like hitting a fourth gear. The pull is outrageous.
Most automatics go through the traps unlocked, hence slipping.
The top end is not a slippin A4's strong point!
