HKS Turbo Timer Type 1 Acuracy?

[Gester]

Just wondering about the acuracy of the 1/4 Mile and the 0-100 Timer readings that this thing gives. Are they fairly acurate? And how do they actually measure this? By the wheel rotations?

I have one on my 33. I think they would be reasonably accurate if it were possible to calabrate the speedo part accurately as you can only really do it off the cars speedo which isn't too flash. Know anyone with a laser gun?

All the times I have posted with it seem fairly correct though. Want to take it Willowbank to get an accurate comparison, that will tell the story.

It is hard to find 1/4 mile of staight, flat road to get a good reading.

Yeah thats true finding a clean stretch of flat road isn't that easy. But do you think the reading it gives sounds fairly accurate?

[jlnewton]

Well, I range between 6.00 and 6.7 for the 0-100km/h depending on wheel spin and I have only done one 1/4 time and it was 14.02. For the mods I have (3in exhaust, pod filter with cold air box, BOV, good suspension and tyres)) that seems fairly reasonable.

I did get one 5.3 for a 0-100 down a hill!!!

The results are certainly not ridiculous. I will have to wait for willobank to see how close.

I guess though it doesn't count the reaction time. So you should probaly add .7 secs or so. Im not sure what people's standard reaction time is. What do people usually get as a reaction time?

reaction time does not count against your 1/4 time. It just means you are more likely to lose.

I think the hks gear is fairly accurate, I hit someone in the head with the turbo timer from a distance of 30m in strong winds!

Reaction times aren't included at the strip anyway. You could sit in stage for 15 minutes and still run a 10sec pass. Reaction times become a factor simpily to beat the other guy over the line. Especially becomes critical in handicap events. Times are taken from when you leave the staging area. With the type 1 timer it taken from when the wheels start rolling, same thing.
