Momentum? m*v? How does this play a role in acceleration? Two cars, same mass. One is accelerating through 80 mph and one is steady at 80 mph. At that instant when they are at 80 mph, they have the same momentum...

The car accelerating has a clear advantage.
Physics aside for a minute, if I'm at CalSpeedway going 90MPH on the straight away, and a car behind me is flat out accelerating from 30-150, you don't think his 90-150 time will be better than mine?

http://www.m3post.com/forums/showpos...73&postcount=2 On his ESS kit, he posted dyno, drag race slips, and vbox times. Since then, he switched kits, dyno'd, ran drags, vbox times and hasn't posted any of them. You have to assume they don't have anything to brag about yet. So all we get is this fluffy video that shows nothing at all, not even the rear camera angle that you can clearly see mounted to the car. My buddies were at this event, and LM refused a rematch with this car. Wonder why (not). Quote:
I downloaded NikB's AA dyno files from the s65dynos.com dyno database and I input them into CarTest. This way, the model is based on real life dyno results on an actual AA Stage-2 Level-3 car. Then I ran two tests on CarTest: 5MPH - 200MPH, and 70MPH - 200MPH. Since the race in this video starts at 80MPH, I figured this would simulate the exact scenario in the video and we could see (based purely on physics and the dyno results of being "under boost") if a running start makes any difference. Here's the results. Both cars accelerated from 80-200MPH at exactly the same rate. See charts below for each test. Quote:

Technically, if you are looking at the equation only, then yes, the momentum is the same. However, you forget about the inertia. The car under steady speed has no acceleration and thus, has to break its inertia to accelerate. The car accelerating does not have that problem.

This is such an easy concept to understand and replicate. Velocity is 80mph but acceleration is 0 on one of the cars while the other is positive.
Get both videos and look at the rpm of both at the start point End of story. Plutonium- Next time you are driving please replicate this scenario with a friend in another car while on the phone. Post your results below. Last edited by SflBimmer8484; 08-09-2013 at 01:37 PM.. |

I will actually be racing at the Houston Grand Prix when the next AirStrip Attack is, so I will unfortunately not be able to attend (Was seriously looking forward to it) Any other Gen2 Level3s in CA?

We have a couple level 2's and some level 3's roaming around Cali now.

All of our level 3 kits have been extremely consistent in different climates and run within 10-15 whp of each other. This is why we chose to integrate a meth system. Not for power but for consistency. Last edited by SflBimmer8484; 08-09-2013 at 09:08 PM.. |

Here's the updated video that fixes the gear starting issue. Even though the other races were DCT vs. 6MT, they were changed as well to make them as close to the same starting RPM as each other. I hope this is good enough, and I hope one of your cars shows up at the next Shift-Sector event. Quote:
