I agree completely Bruce. There's lots of discussion on dyno differences out there. That's why I use a G-Tech and on-road testing. Every good tuner uses dyno testing combined with road testing to get a complete picture of an engine's performance. However, it seems there are more folks with dyno data than have a willingness to do 0-60 or in-gear times. My favourite way to gauge performance changes with my autocross car are simple 30 to 70 km/h (in second gear) times. These are easily repeatable tests with no shifting, wheel spin etc. to deal with. Using a G-Tech with my auto westy to do 0-60 times also produces reliable and reproducible results. I think the biggest problem is that very few actually take the time to check before and after they make a change. It's such a simple thing to do, I am puzzled why more don't do it. This and every other list, despite being storehouses of good data, are also full of information, argument and pointless comparisons that are completely un-correlated with any measurement...drives me crazy. |
