FI with continous high speed driving 130MPH+

wouldnt weight also be a factor in this or are you just setting one weight in the equation?

i mean with higher HP youre typically adding weight with engine parts, turbos, coolers, etc...

i know it may not matter since its just a simple equation for fun purposes but just a thought lol

Take a look at the spreadsheet I put up in my thread.

These values are calculated taking into account weight (I had it set at 3300 lbs), wind resistance (assuming 0.30 CD) and the torque curve of our cars. What I did was took a stock dyno chart and then scaled it up to get the desired peak hp's. Again not entirely correct but I believe is a valid assumption as typically the TQ curves are just magnified when adding boost.


To add to my other post.

Time from 0-160
640hp = 12 s
550hp = 14.3 s
500hp = 15.85 s
450hp = 17.9 s
400hp = 20.5 s
350hp = 24.2 s
300hp = 29.7 s


Again just based on the math.

At speeds such as those weight really plays very little in determining power to overcome resistance at those speeds.

ok thats cool. i cant look at it since i'm at work and dropbox is blocked due to it being a online storage type and possible viruses etc...

I think the best to do is to try it out and see the real result. Like I said before on my previous post: I paid a professional driver to test out my GT3 RS MK2 for absolute top speed. The car was bone stock and had only 450 hp at the engine. Indeed, the guy topped out at ~194 mph. Now, that GT3 weighed only 3022 lbs. However, I think, but I am not 100% positive, that my GT3 had a much better aerodynamic over this stock 370Z and that's why not much hp needed in order to get up there..... and it got up there pretty strong with not much struggle.

i think the GT3 is also .30 drag coefficient as well. and to be honest .30 isnt bad at all considering the GT-R is .26 and thats really good. the new lambo aventador is .33 DC so the Z is better than a lambo yea i said it lol

The lambo is so bad because look at all that surface that the air brushes up against, haha.

A rough estimate (using the 370z gearing) shows it would top out right in the ballpark of 198-205 mph. This is assuming it has the same 0.30Cd.
