Hi Fun with this thread! Good initiative. I thought I could repost the latest test I did where I tried to compare CFD with a real test in dyno.
Can not say that I became completely wise but a simple little test that can still give an insight into what CFD can do. (For oneself, however, there is a long way to go before you feel that you know what you are doing)
Engine: tm kz-R1
Dyno: Dynostar
EGT: Auto release 550 ° C
Compensation: 0.025 hp / kmh driveline loss (shown as 0.03)
Water temperature: 50c ° (external temperature controlled coolant)
Test: Dyno
Purple: With air box (Righetti)
Green: Without +5 on jetting for the same EGT for all below
Red: With little Bellmouth
Blue: With huge Bellmouth
Test: CFD
- Without Bellmouth
- Little Bellmouth
- Very large Bellmouth
No amount of experimentation can ever prove me right; a single experiment can prove me wrong.
