That is still very fast for pump gas, good job!

 

That's an eye-opener. Even a 2% decline equates to almost a 0.4s faster time. Couple that with some tailwind and one can really get some fast times. As an aside, I find it interesting that times are reported to the hundreths place even though the Pbox is measuring at 10 Hz which corresponds to an accuracy of +/- 0.1s.

 

I can see the ET, it's the trap speed that is interesting.

 

Hey Shotcaller are you using launch control ? I'm heading to the drag strip to test my car when it gets a bit cooler. going to test out LC and then without.

 

Yep and the car was on sport mode ( not sport mode + )..Tires still new but i guess it has too much power

 

I wonder what stock pdk trap??!!! any idea???

 

Here ya go:

60-130 in 10.11 on a 0.7% decline, and...
1/4 mile in 11.47 @ 123.7

And the link to the thread

Scott verified it on post number 11 in the above thread.

In order to allow people from all over the world to participate, some slope needs to be allowed to account for hilly areas. But, I still needed to draw the line somewhere.

On that note, RS38's calculations don't line up with what I've seen from validating close to 1,000 P-box runs. Many more variables involved than just slope. What's interesting is that my fastest times have always been on slight inclines. Go figure...

The number reported is the number the P-box spits out. I keep the process pretty simple.

 

The P-box measures the trap speed as it actually was at the end of the 1/4 mile. Dragstips don't do this. Dragstrips take the average between the timer at the finish line and a timer that's located 66 feet before the finish line. Thus, it's a lower number than what the P-box reads.

This is one of the reasons I don't allow P-box runs to count towards the 1/4 mile list.

 

thats was great from just a flash ...

good luck with mods

 

absolutely outstanding for just a flash and pump fuel

 

I still think it is not bad trap speed since Mike FAST SPI 750 tip car in russia trap 132.5 on VBOX ( if im not mistaken )

 

Any decline makes a massive difference in times.. I normally test my cars on a completely flat road with ZERO decline, and as an example my best time on pump 91 was 5.7 60-130... I ended up trying that same run on the same day on the way home on what turned out to be just a .04% decline...just a fraction of the 3.0% that is allowed and turned 5.47.

 

congrats on a sweet car shotcaller.

Is there a "standard" way to do a 60-130? I know some people start at say 50mph and stomp on it to build boost.
In my opinion, I think it would be more useful for comparison purposes if the tester was rolling at 60mph and then stomped on it. Then you could compare b/w different cars. For example, there are a number of cars that have verified 60-130 of about 7.8seconds which is the same as a ZR1 but my impression is that if you were rolling at 60mph the ZR1 would take off instantly when stomping on it but a Pcar might have just a slight delay while waiting for boost. Thoughts? Don't want to hijack this thread but I thought it was sort of relevant to the topic in general.

 

If you had re-done the run on the same side of the road, with no decline, your time would have changed as well. While a decline does indeed help times overall, there are many other variables that also help.

This is why some of the fastest times on this forum have been produced on very flat roads, or even those with slight inclines. There's much more to it than slope angle.
