Historical results - Expert Winners from 1999 & their best lap

[Kitt]

right around the 125 best times. Oddly, the sv and 125s are a match on paper. In racing, the SVs have the advantage because the accelerate out of the hole and you can make a lot more mistakes without suffering as much on the time sheets.

On the front straight they are almost dead even, but only if the 125 winds up the revs from deep in T12.

It's the last 3 seconds that are the tough ones Pete!

x2...

Pete's quest from 18's to 15's is just as bad as my 15's to 12's

I'll be happy with 1 sec per season... ok maybe 2

Johnny B posted a pic of Tom on the new pavement in 8. From what I can gather the change happened mid 99. I talked to #6 also and he seems to think it was mid 99.

mike, you running a MW or bigger this year? if so, what bike?

[Paul_E_D]

Kitt, I'd be happy with ANY improvements at that point as you are at a time that is often the stopping point for most.

.5 a second in a season is good progress. You really need to be able to repeat your best times over and over in practice and then systematically try to change your technique to try an whittle the times down. There are no more leaps forward.

nothing i dont know! after wasting a year with tires that wouldn't work, I got on dunlop and dropped almost 2 full second in 2 weekends... backing up times with 6-7 laps within 0.5 sec of eachother.

I have heard the yami does well at Loudon, and hoping to get some one on one time... I think I have a second in the yamaha/brakes that work alone, but with some one on one, I should hopefully see 14.XX this year.

going quicker..

Here’s where to pick up time but more importantly distance over competitors.

If you can come out of T12 faster , you gain huge distance advantage on the front straight.
The simple reason; you carry that extra speed all the way down the front straight.

Loudon front straight is 1500 feet
Example R1**
T12 exit velocity 40mph
T1 Terminal Velocity T1 (before braking) 120mph
Average speed down straight 100mph *
Average distance per second 146.7 feet per second
Time to travel front straight 10.23 seconds

Example R2**
5mph faster out of T12
Average speed down the straight 107.5mph
Average distance per second 157.7 feet*
Time to travel front straight 9.51 seconds


Another way to more graphically point out the potential advantages
- R2 gains 11 bike lengths per second over R1 or 13.8 bike lengths just down the front straight!

- Coming out T12 faster: a rough rule of thumb
3mph = ½ bike length per second quicker down the front straight
5 mph = 1 bike length per second quicker down the front straight
9 mp = 2 bike lengths per second quicker down the front straight

R2 could be R1 coming out of T12 quicker or competitor is R1**
*for purpose of example used linear rate of acceleration
** for purpose of example assumed both bikes/riders are very closely match in performance.

Finally : I have stood in most corners at Loudon taking notes and watching the fast guys, their line, brake and acceleration points etc.
Nowhere is it more dramatic then exiting T12 where they get the biggest advantage over very similar competition- the most advantage on the whole track is speed exiting T12.

rick has done a 1:16.2 on his ss sv
todd b has done a 1:15.9 on his ss sv

for 09 my money would be due to
a = F/m

a= acceleration
F = force
m = mass :-)

will be interesting to see the "m" not being a huge handicap for one of them.

everyone that wants to get faster should see the fast guys exit 12. i was speechless the first time i saw it. huge difference from everyone else.

+1
The only place to get the true picture is on the grandstand side where they turn on the gas coming out/through 12...

#11 Brett Guyer comes to mind.....sic - on that Big air cooled Duc.

I remember watching him drive out so hard he was nudging the wall with his shoulder/elbow/knee and keeps on going.

RIDICULOUS.

[xsiliconkid]

alright, so what's the best year to compare? When did they make what changes?

if we could agree on the changes,year and time impact then it's as simple as diff the times

[nt650hawk]

ive been trying to convince tom barry to get back on the track... he had the honda hawk record for long time ... never got to finish a race with his built motor.

Hey Rob,
He could not break out of the 19's. He had a 19.0XX

[The Magician]

Yeah... but he has a built motor now.. just needs to get to the track lol. I think the thing makes mid 70s for horsepower.

Did you get an R6? I do find thme easier to go fast on than other 600s, but that may be because they have the powerband of a 125!!!

[jtaylor719]

Thanks Graham!

Now I only need to concentrate on going deeper into 1, a better drive out of 2, later braking in 3, 6, 9, and 11. Then 5-9mph faster coming out of 12.

Oh, and lose 10lbs.

No problem.

yea... 09... think the powerband is a little diff in 08/09 than 06/07, but we shall see how i do on it!
