Hello,
Spent a couple of hours on this site:
HP Loss Aero Drag Calculator
I guessed by installing a under belly pan (full) that you can reduce CD from 0.33 to 0.30. (10%)
Frontal area 1.900m2
__________ 0.33cd ____0.30cd
Speed_____HP Loss____HP Loss__BHP GAIN after underbelly pan?
10mph_____0.00 _____ 0.00_____0.00 bhp
20mph_____0.40 _____ 0.30_____0.10 bhp
30mph_____1.20 _____ 1.10_____0.10 bhp
40mph_____2.90 _____ 2.60_____0.30 bhp
50mph_____5.60 _____ 5.10_____0.50 bhp
(96kph)____9.70 _____ 8.80_____0.90 bhp
70mph_____15.4 _____ 14.0_____1.40 bhp
80mph_____23.0 _____ 20.9_____2.10 bhp
90mph_____32.8 _____ 29.8_____3.00 bhp
100mph____45.0 _____ 40.9_____4.10 bhp
1. Is it right by knowing the hp loss during speed increase you can then say it's like a horse power gain AFTER installing mod?
2. Say for performance gains. 0-60 (0-100kph) is a mere 1bhp? I mean that is like negligible.
Can someone who works with a lot of these online calculators discuss here with me please. Sorry for inputing data in mph.
