Doing 2 pulls is not a large enough sample to compare results.

Have you considered that noone posted a comparison because we all have better things to do than try to figure out how to match your specific setup, location, and conditions overnight? It's pretty easy to go do a thing that cannot be easily repeated. You have to put a lot more effort in to perform a real experiment. We have a 0-60 (mph) times thread already if you want to post "look how fast my car is" logs. If you actually want to have a technical discussion you are going to need to try harder. Basic scientific method: If you want anything you say to be taken seriously, start with a single question and hypothesis. At this point I can't even tell what you are trying to prove. Throwing results out there and saying they prove you were right about some undefined thing does not help your case. Next, design an experiment that disproves the hypothesis if said hypothesis is wrong. For example, dropping two items with different mass from the same height proves that acceleration due to gravity is independent of mass if the items hit the ground at the same time (assuming no other factors). Otherwise the hypothesis is false. Here, you have, among other issues, essentially created the famous hammer and feather experiment. There are parameters you have failed to account for and they have confused your results and brought doubt to your conclusion. Third, someone else has to be capable of reproducing your experiment and results. In fact, real scientific results are not accepted until they can be reproduced by another lab. Otherwise, this exact situation occurs. If your results cannot be reproduced by an accurate reproduction of your experiment, then you don't have a valid experiment in the first place. Here, you haven't sufficiently documented your experiment and haven't given anyone enough time, or even a reason to care, to reproduce your results. ... I've offered to do the math on pulleys twice now and will repeat it here. Math does not lie or exaggerate. It has no motivation. It simply is. I just need stock numbers for the model.

If your aim is to compare potential gains from the pulleys you need to post a pull with stock, and a pull with the aftermarket. Preferably at least a few pulls of each. If you do not have a stock set of pulley's PM me. You pay shipping I will pull the set off my spare motor and send them to you, it is a 13' though, don't know if that will matter. |

I actually could accept that. The problem is that he is doing neither. He simply feels he know more than everybody else and can not recognize that anything beyond his own theories as fact. This results in twisting things to meet his expectations and if you do not agree then you are being a jerk.

My car "feels" faster, sounds louder and seems to run better every time I wash it. I at least understand that it is just my brain playing games with me.

As long as ambient temp was close I would be willing to accept it. I know it's not perfect, but I have an idea of what the result will be anyway.

This! Do three dyno pulls back to back to back and the variance between pulls will be greater than the 0.01 second difference you claim supports your mods made an improvement. Doing second gear pulls is also way more likely to introduce variations between pulls. There's a reason that real dyno pulls are done in 4th or 5th. The longer gear gives more data and helps naturally smooth out tiny variations.

Doing two pulls is not enough? Ok, but I wouldn't expect a 40-100 km/h timing to be THAT different on a 3rd or 4th pull. Maybe some small differences, but not THAT different. |
