Because HP requirements change as the cube of velocity, and drag changes as the square, your numbers may actually prove something. The HR camaro does 246mph, with a .21Cd (your number). After going through the equations, it takes almost the exact same power to push your car to a slower 200mph with a Cd of double, ie .42, also your number.
Interesting huh? The actual numbers came out as
[email protected] = [email protected], given the same HP numbers
So, it stands to reason that your car will reach 200 with approximately the same HP as a 572GM crate engine. I think I remember tests putting it about 800 at the crank.
BSFC numbers are fuel flow, you can get pretty close using them. |
I wasn't debating the approx HP to get to 200mph, just stating its a random # in your first post. Keiths camaro had 5 miles to get to that speed (going by memory again but I'm sure this was a salt flat #), I plan on hitting over 200 in less than a mile (and yes I know keith has done this as well). The comparison is still flawed because of rate of acceleration is using over 800hp. At every corner the acceleration can be more than 800 hp. I have allready done all these calculations in 100 different ways ages ago. All the formulas you are using have been pinned up in my garage for years I just wasn't going to redo my calculations based on this discussion, not knowing from the beginning I would have to prove myself. You must have a lot of time on your hands. lol
Probably a better discussion elsewhere, this is still a build thread.
P.S. I know what BSFC numbers are and I'm still keeping the 45 gallon cell
