Yes , Aerodynamics Losses are growing at a Cubed Rate !This! At the top end, the drag force per HP has a rapidly growing effect.

i never ran a Quarter Mile simulation on George's ProBike ... i just ran/checked his posted Engine Data in v4.00 PipeMax to see correlationsStan Weiss wrote: ↑Tue Apr 17, 2018 11:13 am Larry,
I do not know if you ever ran any simulations on the data that George said that I could share with you? I used .52 and 5.5 which is 2.86 and for my simulations that seemed to work out very well against his actual run numbers.

Jerry Savoy's ProBike usually has the fastest 60 Feet times of all the Pro Bikes !!!maxracesoftware wrote: ↑Tue Apr 17, 2018 12:42 pmi never ran a Quarter Mile simulation on George's ProBike ... i just ran/checked his posted Engine Data in v4.00 PipeMax to see correlationsStan Weiss wrote: ↑Tue Apr 17, 2018 11:13 am Larry,

... at least i cannot remember doing a 1320 ft analysis of each foot distance
i might have done a quick sim of just 60,330,660,1000,1320...no real in-depth study
i probably have George Bryce/Angelle Sampy 's best Runs/incrementals logged
but if you like please post the incrementals , ( or any screenshots of your Sims on ProBikes , etc )
because i have that Data logged ... but no actual Team or Racer's name next to each Data Line
so it might take me hours researching to matchup Incrementals to actual Racer's name
How did Bryce/Sampy best 1320 FT MPH compare to similar 1320 FT ET from a ProStock 500cid V8 ?
It has been a few years since I did this so I any not sure where all of the data is. If you need anything else ask and I will see if I can find it. I also may have to email it to you.Hi George,
I ran a simulation based on one I had done back at the end of the 2013 season with some input from you. I added some traction and adjusted the weather / dyno correction factor.
60 Foot ET = 1.0461
330 Foot ET = 2.8086
1/8 Mile ET = 4.3022
1/8 Mile MPH = 164.0001
1000 Foot ET = 5.6116
1/4 Mile ET = 6.7311
1/4 Mile MPH = 201.0191
With the pro stock cars my MPH is normally a little low while here it seems a little high.
For that run with a 1.040 60 foot time I get
60 Foot ET = 1.0400
330 Foot ET = 2.7989
1/8 Mile ET = 4.2917
1/8 Mile MPH = 164.0656
1000 Foot ET = 5.6008
1/4 Mile ET = 6.7201
1/4 Mile MPH = 201.0463
The only way I can get the MPH to come out the same is if I have the engine hit the rev limiter before the finish line.

Me too LOL.
StanThanks Stan for asking and keep it private.....i am okay with Larry....please ask him to keep it that way , thanks

( not a Forum Question, instead 1320 Feet MPH Comparisons info )
ProStock V8 500cid -vs- ProStock MotorCycle 2 and 4 Cylinders
even though the CDA of the ProBike is less than that of a ProStocker
the ProBike's 1320 Ft MPH is often 3 to as much as 7 MPH slower )
even though the incrementals at 330, 660 , 1000 are very close in most cases
and even the 660 FT MPH are still very close...but by the time you get to 1320 FT
the more Cylinders + larger CID have more MPH
basically the same thing can be seen even if the CDA's are closer
like in the Automatic/Converter Cars with V8's -vs- 4 or 6 Cylinders
they likewise have lower 1320 Ft MPH than V8 Engines
CDA = the Drag Coefficient x times the Frontal Area in Sq.Feet
CDA = the Drag Area
PhotoBucket went down ,Unfortunately the images no longer display. Where did the straight six come out in comparison?
would be the same results as V6straight six come out in comparison?
