at 8:16pst May is 2.04 seconds off pole in 6th. http://live.amaproracing.com/rr/ | ||

Hayes has a trap speed of 200mph!.... and it's only Thursday! if you look at the segment times ( S1, S2...)G. May is better than Hayes except for S4 - which the timing sheet is showing "green" which is G.May's best time..looks like they need top end speed to break into the top 5 | ||
| Davegess |
That top difference is nuts. What are those fast guys running? | ||
| Reepicheep |
Nice. Geoff put together fantastic times through every segment on his last practice lap. Forget the hulk, call him the surgeon. http://results.amaproracing.com/xml/rr/events/R120 5/sbp1ind.pdf | ||

So 1st is trapping 203 in some runs, and the 1190 is doing a best of 192? Needs more power I guess. | ||
| Reepicheep |
Mathmatically and from a simple physics standpoint, I think a Twin with with 1200 CC's always be at a power disadvantage to an inline four with 1000 CC's. Always. Any technology you could apply to a twin to get it to rev high enough to close the gap could be applied to an inline four to re-open the gap. So that's perhaps just a rule based inequality we will be forever needing to overcome. The twins hopefully have other advantages over an inline four that can close the gap in horsepower (as a race is a race, not simply a dyno shootout). | ||
| Davegess |
The advantages the twin has are more apparent at other tracks. Daytona is pretty much about POWER and top speed. No where else do the bikes spend so much time flat out. | ||
| Deanh8 |
If they are trapping more than 10mph faster that takes away from the torque advantage for sure. 10mph is massive. | ||
| Reepicheep |
There is no "torque advantage" on a race bike. Horsepower is what propels a bike forward. The more horsepower you have, the faster the bike goes, period. There is an advantage to a twin that people call a "torque advantage", but its really the wrong name for what it is. What they are saying is that at lower RPM, a twin might make more horsepower than an inline four at that same RPM. The problem is the guy (or girl, go Melissa Paris!) on the inline four can simply drop a gear and make more power. And in a race, they will. The twin can't drop a gear, because they have a lower redline, because the have two bigger pistons moving through a longer displacement than the four smaller pistons of a four moving through a smaller displacement. The twins are nicer on the street though, because running through a residential neighborhood on a sunday afternoon taking your kid to Lacrosse practice at 12,000 RPM just makes you look like a tedious and annoying idiot. So in that case, making better power at lower RPM is desirable over making higher peak horsepower. For what that's worth... Dave Guess made a great point... A dry Daytona track rewards bikes optimized for maximum peak horsepower. But other tracks (or conditions) reward bikes that pay more attention to the overall smoothness of the power gain as RPM (and therefore horsepower) climb, but sacrifice ultimate peak horsepower to do so. It's all part of what makes racing fun again!  | ||

Just don't forget Erik was quoted somewhere here on badweb as saying they'd found more hp this winter, and were topping 200 mph. And apparently Geoff was told to..um..."Behave" last season. Maybe he's being told that in qualifying, too? I think its great he's only 1.90 off the pole, and I can't wait till that green flag drops in anger tomorrow and saturday!! | ||

Please tell me you had him on the back with all his lacrosse gear on — stick lashed to his back like a ninja. | ||

Correct me if I read this wrong. On his second lap, Eslik was running 205.058 MPH. I went through all the riders. There was only one rider with one trap speed faster than this. R. Hayden on a GSXR-1000 went 206.091MPH on one lap. This says trap. Is this really how fast they are running, or is this some sort of corrected value? | ||
| Reepicheep |
You couldn't see the lacrosse gear because he had a riding jacket over the pads. The sticks (two, I coach so I had one also) were bungeed to the bag on the triple tale. Next time though we will strap it across his back. | ||
| Ratbuell |
strap 'em in an X. (visions of the Road Warrior dancing in my head...) | ||

>>> Is this really how fast they are running...? Yes, as reported by the data acquisition system employed by AMA Pro Racing. | ||

Trap speed isn't as important as you might think. Geoff's best lap (1:40.354) in Q1 had a relatively dismal trap speed of 188.30 mph. His best trap speed of 205.32 mph got him a lap time of 1:42.068. http://results.amaproracing.com/xml/rr/events/R120 5/sbq1ind.pdf If you add up all of Geoff's best segment times, he ends up with an ideal lap time of 1:39.914. | ||
| Brumbear |
It does speak for the power of the bike though and 205 MPH is frightening!!!!!! Now if they dial her in look out  | ||
| Zac4mac |
Where is Shawn Higbee? | ||
| Pmjolly |
Zac, check this on the Quick Board. http://www.badweatherbikers.com/buell/messages/406 2/671582.html?1331902572 Their 1190 dropped an exhaust valve. Not good. | ||

Racing often has tough breaks... it's not easy at that level. | ||

This was on RoadRacing World: March 15, 2012 Free Practice Two Trap Speeds: 1. Roger Hayden (Suz GSX-R1000), 206.40 mph 2. Josh Hayes (Yam YZF-R1), 205.42 mph 3. Geoff May (EBR 1190RS), 205.32 mph | ||

Also from RR World today: March 16, 2012 Provisional Combined Qualifying Results (2.9-mile course, all on Dunlop tires): 1. Josh Hayes (Yamaha YZF-R1), 1:37.463 2. Blake Young (Suzuki GSX-R1000), 1:37.890 3. Roger Hayden (Suzuki GSX-R1000), 1:38.132 4. Josh Herrin (Yamaha YZF-R1), 1:38.342 5. Ben Bostrom (Suzuki GSX-R1000), 1:38.610 6. Chris Clark (Suzuki GSX-R1000), 1:39.474 7. Steve Rapp (Kawasaki ZX-10R), 1:39.501 8. Jake Holden (BMW S1000RR), 1:39.580 9. Danny Eslick (EBR 1190RS), 1:39.677 10. Robertino Pietri (Suzuki GSX-R1000), 1:39.698 11. Larry Pegram (BMW S1000RR), 1:39.772 12. Geoff May (EBR 1190RS), 1:39.991 It is a long race, really like an endurance race--a lot can happen... | ||

what does the green dot mean where the pit symbol goes? they really need a legend. | ||
| 99buellx1 |
Crossed the finish line under green flag, no change in position. | ||
| Smoke4ndmears |
thx. | ||
| Albert666 |
how do the buell race bikes compare in terms of fuel? in world superbikes for instance they use 21 litre fuel tanks, obviously with fuel in the frame its not as simple as making a larger tank or do the frames hold more on the race bikes? | ||
| Jdugger |
They use this thing that's like a ping pong ball to reduce fuel capacity if required... | ||
| Albert666 |
oh and regarding trap speeds carlos checa was never the fastest through them last year, didn't do him any harm | ||
| Mickeyq |
I will never forget the race back in 1982. Freddie Spencer was on the 200Bhp Honda V4 FWS1000 and Kenny Roberts was on a @685cc OW. Freddie was flying by KR all through the race--but had to stop 2 times to change tires. KR won by keeping a steady helm right to the end. I think Danny and Geoff will be in the hunt in the final laps. Can't wait to watch this unfold. Good luck to Team EBR!!!! |
