340 Vs 360
Paragraph 1 is exactly correct. It’s like you have never been at the track and done any testing.
You can two exact engines with the same power (say 500) and the one with the lower BSFC will be quicker and faster every time.
We haven't been talking about identical engines.
We've been talking about comparing engines of different displacement, but otherwise the same.
We've been going back and forth for about 100 posts and you still haven't given an explanation as to why you think X average horsepower at a higher RPM range will move the car faster than X average horsepower at a lower RPM range.
As for BSFC If you can explain how a car becomes faster purely because of reduced fuel consumption without increasing the available horsepower, I'm all ears.
That oughta be good.
Ive said this before so I’ll give you the benefit of the doubt so I’ll say it again.
A water brake dyno has limitations.
I never said anything about a water brake dyno.
We were talking about comparing how two engines of different displacement, which make the same average horsepower over different RPM ranges *in the same weight car* would perform.
naturally, with both configurations having optimized gear ratios, chassis etc.
You still haven't provided a credible explanation as to why you think the smaller displacement higher RPM version would provide a quicker ET than the larger displacement lower RPM one.
You started talking about how X horsepower @ 7200 rpm will be faster than X horsepower @ 5200 coz it has more power strokes per second.
But you seemingly want to ignore the fact that X horsepower @ 5200 rpm mathematically must be making more torque than X horsepower @ 7200rpm.
If you don’t know those limitations and UNDERSTAND them you won’t ever grasp the concept of two engines making the same power at the same RPM having two different ET/MPH.
We were specifically talking about two engines making the same horsepower at *different RPM*
Are you going senile?
This sentence literally makes no sense at all.
Figure out what the limitations are and it will start making sense.
Or continue on ignorant of what a dyno is and what it does.
Again, I never mentioned a dyno.
