Is 100-200kmh the new measuring stick? I don’t see a lot of 0-100 times posted.
thats because the early cars were all manual. Hoping to see 0-100 and 0-60 times soon as more pdk cars start being delivered. Rolling pulls levels the playing field manuals have no chance on the launch. 100-200 will separate the bolt ons and tunes with much greater resolution.
When you start getting close to the maximum allowed downslope for a valid run you're gaining significant time on a fully level run though... (just looking at the Dundon one)
If these results are for "scientific" comparison purposes it would be great if they were on +/- 0.2 degrees or so roads in terms of slope.
Ok I went out for a couple rips with just the @BCFABS headers and stock muffler to see if this makes power... and it sure does. The catted 200 cell street headers are currently the only mod on the car. Nice job boys, for the new kid on the block well done lads.
I am not a racing driver, the DA could have been better, 1/2 tank gas and the slope was bang on 0.00 for the 60-130. I did 2 runs the other was 8.19/9.48. I feel like there's more in it with a lower DA and some downhill this can hit 7s with the stock muffler. But only on a hero run with fudging. I think the full system makes more power but Im not certain the gains will be maintained in hotter temps (like in the summer) enough to really matter. The big benefit there is sound IMO. And theres alot of it.
Ok @JCR-Porsche are you ready to show us your 7's yet? @Jamie@dundonmotorsports Looking forward to you guys going back out and doing some more pulls with the crack pretzel.
This is fun and cant wait till the tuned guys and short ratio guys start posting as well.

Looking at the relatively long "flat" spots in the graph where acceleration is interrupted due to the shifts, if you really slammed in the gears it may just dip into the 7s already. That's an annoying variable (the level of mechanical sympathy one possesses) that isn't an issue for the PDK cars.

Yeah I was trying not to send the trans to the moon. I agree I think the current setup may have 7s in it. Im not as good of a driver as the pros and this car is expensive so any faster and the cheeks start to clench. Its also not easy finding somewhere to do this unless you are in remote mexico or on the track.

I get what you're saying. I did those runs on our local track so I can't really control the slope better than that I think there's a 7 in our car if I can get my business together

Here's the guy with the PDK car and Dundon headers overlayed on Rennolazine's nearly identical time with the manual car. As expected, you can see that the lighter and lower drivetrain loss car does manage to catch up what it loses shifting pretty much. Actual engine power is probably very similar.
However, despite the fact that these cars have an identical 100-200 time, in a straight up rolling drag race the PDK car would be ahead at 200 km/h. Slightly counterintuitive, obviously, but it has a higher average speed therefore covered a bit more distance in the same amount of time.
Personally I think the fact that a manual "feels" a bit faster to the driver makes up for the fact it does in fact lose to the doppelkupplungsgetriebe.

i disagree. It took me 3 less meters to do the run. Dragy also records distance 354 vs 357 m. I am 3 meters ahead. 1 car length. Boom
and ted is 1 car length ahead of me.
its right there on the strips gps tracked...

Well the math doesn't lie... also the GPS speed is more accurate than the elapsed distance. I promise you if you race a PDK car and you both reach a set speed like 200 km/h or 130 mp/h in the same amount of time you will be visually losing to the PDK car. Because there are times right after a shift when you're traveling at a significantly lower speed but you never go faster than the PDK car by the same amount to recover the distance lost, you only get back to level speed.
If you keep going until you're basically doing Vmax this theory will break down eventually though.

I can visualize what you are saying. I cant be winning if Im losing speed. But the GPS calculates speed based on distance. So if the distance isnt accurate, then whats happening?
