RG Racers: Drag racing mosh pit
RG500s burning rubber around the globe..
... and the place for making excuses
I'm a numbers geek, and I can't help myself sometimes. So here's a little bit of drag racing data that I have gathered so far. Perhaps we can get more?
Randy Norian - rg500deltamailto:rg500delta@mac.com?subject=Drag racing RG500@mac.com
Some data Marko shared:
first pass ever: 11.97 @ 183.05 km / 113.3 mph
Eventually!! 10.22 @ 215 km/ 133.3 mph
also: 10.29 @ 218 km/ 135.2 mph
That is interesting, because my notes have my first trip to the strip (best pass) as 11.80s at 115 mph, in other words VERY SIMILAR! - RN My first ever pass on the RG was well into the 12s, I remember being very disappointed. Getting into the 11s was a big deal for me.
Marko said his best pass is 10.21 @ 223 km/ 138.2 mph
Alpha and Omega ran 10.25@ 214 km/ 134 mph
Then we have Juha with 10.59 @ 213.5 km/ 133.4 mph
And the poor Delta in last with 10.905@ 221 kph/137.2 mph (uncorrected)
Not sure what Willy Ponting's best pass was.
I have no idea what the other corrections are, you have to keep track of the conditions when you test!
Funny how close four completely different bikes can be. 8-)
All I know is, if I wait until the middle of summer to race again, the incredible heat and humidity will make this an uphill battle. >8-/
2T performance bites when it's 95 degrees out!
In the time-honored tradition of all good racers from around the globe, I must start making my excuses at this time! Here comes the correction factor.
I don't know about Finland, but summer here can be excruciatingly hot and humid. Performance is greatly diminished - fortunately, drag racers use correction factor to standard conditions, to remove the air quality and altitude from the comparison. First, you calculate the "density altitide" which is a result of your actual altitude, barometric pressure, temperature, and humidity. Then you use that density altitude to look up your correction factor.
So the Delta's 10.905@ 137.2 mph happened under the following conditions: 1200’ altitude, 89 degrees F, 75% RH, 29.90 “ hg pressure
Resulting "density altitude" is 3852 feet, with relative density of 89.21%
Here's a great site that can perform the weather correction, there's also an APP, by the way!

NHRA "density altitude" correction charts below:
So, what does that do for the ET and mph? 3800 feet "density altitude" has at ET correction of 0.9536 and a mph correction of 1.0493
So the 10.905 @ 137.2 corrects to 10.399 at 143.96
Maybe there's hope for the Delta after all. Hopefully we'll find out more this summer.
