I love when people say "you have 2 cars with the same hp, the lighter one will win" or "you will need 74.7 more hp to win" that shows a complete lack of knowledge/understading. Who cares about average hp along the entire range, torque, gearing etc. Just the hp matters, LOL. The reason why certian cars seem so fast with "less" hp is because they make lots of hp and torque THROUGHOUT the entire range of power. Just because your dyno queen tops out at 600hp on a dynojet does not mean a similar car will not beat it making 550 (or less) if the car making 550 makes more from 2500-6500 and your making most of yours at the top. Saying what hp your car made and saying what it will beat on paper makes no sense.
OP, I was not getting onto you, just remarking how many people on this site seem to really lack a true understading of power and racing. Also, who cares what happens after 150? if one car has a top speed of 200 and another 160, I think we know who will eventually win, but if you take him by serveral cars until 150, even when he finally passes you, thats your race, IMO.
I just wish people would spend a little more time trying to learn than trying to type. Dyno's, whether they are jets or mustangs are for tuning and seeing if a particualr mod/adjustment is working or not. Nothing more.
Heres a simple question:
2 cars, both the same, except for the cam. One makes 300hp the other 350hp on the same dyno, same day. Both auto's driven by similar weight drivers, cars left in drive. Who wins? (no traction issues)
before you answer, the car making 300 made and average hp of 200 from 2000-6000 and an average of 200 torque from 2000-5000. The car making 350 made an average of 160 from 2000-6000, but made 50 more the last 500-1000 rpms. It made an average of 170 torque from 2000-5000.
Now who wins and by alot? See my point. Looking at final numbers, no chance to the 300 guy, 50 hp, thats a few cars, but not in this race.
Next example: one guys sig 600hp the others 515, same year cobra, who wins? But wait, the 600 was on a 50 degree day on a dynojet. The 515 was on a mustang dyno on a 90 degree day with 90% humidity. Do the math, close ass race. Most people agree 10-15% difference between dynos, so I'll use 12%, so add 61 to the 515 and you have 576, then add/subtract for humidity, even race. Now look at dyno sheets and see who is making more average power/torque, now one has tko600 the other a t-56, lots of variables, way to many to even have a chance at a guess. But everyday on here people are just sure how a race is going to turn out with hardly any info.
Sorry for the the rant.
