All these races from 40 to 100 --30 to 150--- 40-150 are simply sour grapes by a manual trans owner to try and find some extremely odd way for a manual trans now to beat an A8-----Truth is when most guys race it's rarely even a 1/4 mile and then if they do go a 1/4 mile an A8 Z06 still wins-----Who races to 150 MPH ?? no one unless they are at a closed airport---------Technology has changed either accept it or fall behind--

better look at every motor trend, road and track, car and driver, car forums, etc all over forever. it's one measure of performance that is just as arbitrary or relevant as 0-60, 1/4 mile, 1/2 mile, top speed, or anything else that tests limits most will never hit.
with a few of you guys together on here are we could start a TV show called "WTF."

The only reason I did a 40-100 roll measure on the acceleration test, was due to it being accessible and something I could do frequently to measure improvements. I don't have time to go to the track every week or pay for dyno passes to measure HP gains. This was a nice free alternative.
That said, based on our findings the A8's were way behind vs the M7's in regards to roll racing standards. Everyone can disagree all they want, but roll racing is a thing... and it's huge. Taxas2kXX races are insane. About once a month I go out with a few buddies in mexico and we do 30-150 rolls... a lot of them. It's really fun, and not nearly has harsh on the drivetrain. Dig racing breaks a lot of things due to the stress it puts on everything.
This method has worked out for me, and I now have a unique way to measure improvements. Intake Manifold and Ported TB are being installed as we speak! I'm trying to chase Higgs down for the lead

Ordered an ECS kit
Probably going to order the CPR fuel system
Having a 416ci motor built
I have DSteck Flex kit and Z06 fuel parts sitting in a box in the garage.
It will be a while before I get it all together, maybe 2-3 months. I am only looking for about 800rwhp so not a super crazy build but at least cooler weather will be on the horizon by then.
I do want to make a pass or two as it is now; 1/4 and 40-100 but its so hot here, as you know, that I don't see myself bettering 4.8....I could still get to the track for an ET with a DA disclaimer, lol.

So DA is supposed to be over 3300 ft Friday evening. How fun that will be.....track is at 650 ft, lol.
So an 11.0 converts to a 10.68. Basically I will be down around 30 HP.

DA was like 2000 when I ran my 11.08 I think, I know I'll have good air in the fall so these are just test hits.
I don't think many people on this forum would be able to post a better 40-100 time than a blown 416 on E85 lol.
I'll be curious to see how good I can do with headers/intake/tune/150 shot though.

The A8 has a 10.99 overall 1st ratio. Allowing a faster 60ft from the A8. The lower gear allows more traction and a faster start than the 7.83 overall first gear of the M7. So in the 1/4 mile the M7 has a handicap to overcome.
The 1/4 mile is highly dependent on your 60ft time.
A8 wins the standing start 1/4 mile. But when you put the cars side by side in a rolling start. The A8 loses the low first advantage.
The M7 then has the closer ratio's and less drive loss (ie. more power to the ground. The M7 should win the rolling race from 40-50 mph contests provided a good driver is behind the wheel.
Putting that aside the M7 esp teamed with a MGW is a great driving experience.

The A8 has a quicker 0-60 time and wins the 1/4 mile drag race compared to the manual trans---
As far as drivetrain loss vs the A8 and the manual trans---They are now Equal---No advantage in drivetrain los as before from a manual trans---
I think you have to be an extremely experienced driver of a manual trans even to win in a rolling start race-----This makes a lot of manual trans drivers pissed as now an in experienced driver with an auto trans can let the computer drive the car and be quick and the manual trans driver has to shift "perfectly" in order just to be equal !!!
Quickest STOCK Corvette ever is now the 2015 Z06 A8 automatic at 2.9
