Barrie makes it 3 in the 10.6's
Discussion
Congratulations to Barrie Piper pushing his turbo Chimaera to a new PB of 10.68 at 127 yesterday at the pod.
That puts 3 of us in the 10.6's with only a few hundredths of a second between us.

I’ve been trying to find the words,,, I love the competition as Derek will have to build something way out there so I’m kind of gutted you didn’t do it Barry. Kin el 8/100 of a second, that must be like few inches apart!
Cracking car.
8/100 is 0.08 so close to a tenth of a second which in drag racing terms is more than you may give credit.Cracking car.
At 130mph a car would cover over 190 feet per second so that makes just over 15 feet in 0.08 or about a car length.

A way of identifying 2/10th of a second is to blink. The time it takes to close your eye lid and open again is roughly 2/10th. Try blinking 5 times as fast as you can up against a stop watch and it takes exactly a second or near as damn it. At 130mph a car would cover over 190 feet per second so that makes just over 15 feet in 0.08 or about a car length.
So though the distance gap will appear large from one car to another at that speed the time you beat Barry by is all the time I’d takes to blink your eye shut. Amazing
It has taken a lot of time with Ron Haslett to set the car up. We have been to the last three private test days (max of 90 cars) playing with suspension set up and tyre pressures. One of the main things was not to go round and round. We did two runs and parked up to let things cool down and take tyre pressures and log after each run. My best run was the first of the day. Ron's experience has been invaluable and I owe him a beery curry night.

That I would like to see!
To put your run into perspective, it is 1.2 seconds faster then my best. You can just imagine how much distance there is after you cross the line and then 1.2 seconds later and at about 118 mph my car crosses the line. That is one huge distance in drag racing terms!
Respect to you guys!

Going by the way the chassis looks like its twisting Ron’s work is pretty good.
It’s also 2 seconds quicker up the quarter than an Audi R8 V8 which should make us all feel a bit better
Is it corner weighted Barry.
I ask as if that pic is not just optical illusion it looks like more force is going through the right rear wheel. Might be inducing less bite?
Maybe offsetting the car to the near side with ride height might shave a few 100ths off the line.
Need to offset the engine toque+ your body weight so Dif gives best grip maybe. Guessing but it’s a thought

To put this into even more perspective, Longbow in a standard 4.2 Cerbera managed a 12.175 secs run, and I consider his ability to launch a cerbera as amazing.

How can you tell the chassis is twisting ? If the chassis twists enough to be visible by the naked eye you'd have cracked screens and doors popping open .. 
Looks like a nicely load transferring launch with a driver on board to me.
This does lead me on to another question though ..
a std 500 is capable of lifting itself clear of the nearside engine mount if it has failed just under torque reaction from planting your foot to the floor .. what engine mounts system are the drag racers using to prevent this ? the torque reaction from a turbo engine with sticky tyres is what 2 or 3 times what you might see from a traction limited std 500? Do you ever see the gear lever moving up in the transmission tunnel under power (classic sign the engine mount has failed)

thats seriously quick stuff now

I bought the stiffest uprated engine mounts from SC Power many years ago and they have held fine.
I may consider hard mounting the engine with a plate in the future.
If you do make sure you have plenty of squidge (technical term) in the rest of the drivetrain. I solid mounted and engine and box in a race car once (T5 box) , and the gearbox failed the very next outing. Coincidence or not? I just know I'd never solidly mount anything again.I may consider hard mounting the engine with a plate in the future.
