I believe that comparo is not fair

First Race

1- Altitude 660m..Which should let both car and bike ran slower
2- Porsche was on 1.3bar...I wonder why he didnt boost it up since he is in higher altitude
3- The bike started on 2nd and the RPM was lower which give him better start

Second Race

1- altitude 150m..Which should let the car and the bike ran quicker
2- Porsche was on 1.5bar...Ran higher boost on lower altitude..It is advantage for porsche
3- The bike started on 1st and the RPM was 10800 ( near rev limiter ) which is disadvantage for the bike ( coz he will shift directly and )

I believe the Porsche should ran same boost ( either 1.3 or 1.5bar ) and the bike should be in same RPM and gear ( either 1st or 2nd ) on 150m and 660m altitude to see the REAL DIFFERANCE!!!

Thanks

Shotcaller,

i see your points, i came across this video on youtube. I hope i could find the people involved to get some feedback.

I don't think they have any reason to post unfair results, from the comments on their videos i can see that they are cusins, just having fun.

I'll look for Petros who is the biker and ask for more feedback
