Default Dyno Racing - fact or fiction?




Does this this machine instantly shave 2 seconds off your ET?

It did mine LOL!

Not quite sure, are you asking or telling us?

Is that a bike dyno or a racing simulator? Nice looking bike

How can you have an ET when the bike is not moving? Obviously, the computer program is not accurate and not taking into account all the variables such as air resistance and less than optimal rider skills.

Blue, thanks for the compliment on my bike. As far as the dyno goes, been looking all over the web for comments pro-vs-con about results given by it. Had a good time, guess that I'll read into their website a little further for details.

XLXR, I'm guessing an ET could be computed by measuring the ET from the moment the drum moved until the moment/point at which it had rolled a distance of 1/4 mile(?)

Might be over-simplifying it but my mind is a little muddy today, but does that formula sound right in this scenario?

Yes I would say that does sound right. Have you ever run your bike at the strip? Just wondering why you ask about the 2 seconds.

It'll never be identical to an actual strip, but as long as the other guy is beside you it's fair race. All in good fun

What's up man?! My friend was on one years ago. Same result, it was a super quick et for what he had.

It's a lot of fun to watch guys run their bikes on a dyno/race simulator. Especially if two bikes can run against each other at the same time.

I've seen some simulator runs that were right in line with the actual times ran at the track.
But I've also seen runs that were way out of line too. Just because the bike is capable of running a certain time and speed on a simulator doesn't mean the rider is capable matching that time at the track.
The reason is any Bubba who is halfway decent at shifting gears quickly can put down some impressive ET's and trap speeds on a simulator. It really doesn't take any riding or racing skills to get the best times out of the bike on a simulator. You don't have to worry about wheelies, getting your feet on the pegs, balancing the bike, looking straight ahead, etc. Just wind it up, drop the clutch, watch the tach and shift at redline.
Go Grandma!
Just kidding, they can be fun but I wouldn't take the results too seriously.
And don't go around bragging your bike can run a XX.XX @ XXX mph when it's never been down a drag strip before.

edited to add the 11.67 shown by the dyno. It's a carbed 883, seems it should be in the mid 13's ?
