here is the 7.84 run....

cheers, mark

Congrats mark, great run.

I also hope you give HT a hurry up, would be great to see you both chip away at sub 7.50s.

One question if you don't mind as its been discussed on another forum and I'd be interested to see what you have to say on the matter.

Have you found that you regularly get higher MPH when your 60ft times have been slower than ideal ,or if you've had a bit of a bogged or wheelspin launch, do you find that on a good 60ft run your ET AND MPH are better?

Its been put forward that its very common to run higher than normal MPH when the 60ft has been slow and that when your 60ft and ET are real good, your MPH will be lower.

I'd be very interested to hear if you have found anything "funny" going on in this department.

Anyone else who has had experience with this feel free to comment.

Regards Rob

I have found this same phenomenon...you would think it goes the other way...but it doesn't.

The more time you spend covering the race distance, the more time the car has to accelerate. I've always sixtied harder on lower terminal speed passes.

Look at it another way, it's very rare the your PB ET will be on the same pass as your PB TS for a given state of tune (engine, driveline, etc).

Very strange how quicker cars usually run higher mph though?

I've set PB time and mph on the same run a few times but tbh they are usually both a result of a slower 60ft. I'm wondering if the slower 60ft runs are more settled and your able to get power down smoother than maybe a leap off the line that possibly upsets the car?

The phenomina of higher mph with slower et can usually be explained by wheelspin.

Car A frys them till say the 100ft mark before traction phases in will be doing more mph at that point than car b that hooked up and bolted.

Car A Takes longer to get to the 100 ft mark because of the wheel spin, hence the slower et but has already put mph in the bank by virtue of the wheelspin. the extra speed is then carried through the traps for a slower e.t. but a higher mph.

Who's on first. :/

I thought that was what I said?

What's on first!
