What is the best possible reaction time? I can't remember. The shortest I have pulled is a .122 is that good?

 

On the LED lights, like at BMP, a .000 is a perfect light.

On the old sportsman tree, a .500 was a perfect light.

A .122 equates to a .622 on the old sportsman tree.

If you were bracket racing, this light may get you through one, maybe two rounds if you are on your dial-in. To be competitive in a normal night of bracket racing, you better be in the .050 and better range.

For someone not racing all the time, it's a fine light.

 

Any sportsman tree is a .500 tree. Sportsman trees are the one's which have the yellow lights come down one at a time. A pro tree is a .400 tree and all the yellow lights come on at once. When I say a .500 or .400 light I meen any time lower than that meens RED. If you are bracket racing you better be in the .520 or lower range if you want to last.

Mark,
This past Thursday at BMP was my first time with LED lights. They were dropping a sportsman tree and showing reaction times as .000 as a perfect light.

Here's my timeslip with a .073, which equates to a .573 on the old bulbs.

I was kind of caught off guard when I saw .073 and no foul.

Am I right here or confused?
Also- Do you know of anyone looking to get rid of a 4.10 gear for a Ford 9"??? I was spinning too much gear for the 1/4 mile.

Here's my timeslip-

 

They use the L.E.D now and a perfect light is .000.It's hard to get used to it.The old light's were .500 of a second.

 

A sportsman tree is still .500 to count down to a green from first amber, some timing equipment will show it as .000 others .500 as a perfect light, depends on the track and timing equipment that they use... Great lakes dragaway in wisconson had .000 back in the 80's, so I wouldnt say this is something new.

 

I'm no avid drag racer, but I thought I heard something about LEDs being calibrated to have a "delay" to match the old school incandescent bulbs.
Is that right? Any rate...so .000 is a perfect RT huh? There should be some sort of standard to that stuff. Why doesn't NHRA regulate that?

 

I ran a .497 and no red once at a test and tune.

 

When NHRA or IHRA runs a national or sanctioned divisional points meet they bring and use there own timing equipment. otherwise tracks have their own equipment they use and can be set up to show .000 or .500 based on the manufacture's (compulink, chrondek, TSI,) software installed into that perticular system. As an example, Byron Dragway near Rockford IL. and Indianapolis raceway park used a compulink III system that showed .500 as reaction time, Great Lakes Dragaway in Union Grove Wi. used chrondek that showed .000, Cordova Dragway used a TSI "SD" super system that showed .000 and US 131 dragway in Martin Mi. used the same TSI system and showed .500 as a perfect reacton time. My ET slips from the 2 times I raced at BMP in 98 and 02, show a compulink startrak syst, that show a .500. Hope this Info helps..

 

My best reaction was a .547 at Lakeklane motorsports this afternoon....................... how would that calculate
