Getting closer Perry!

Can you do anything about the obvious asymmetry in the launch, where the passenger side front wheel lifts much more than the drivers side. A torque tube maybe?

Nah its easier than that, ballast the left side, by converting it to LHD,

More fact than fun,

You dont want to do that, it is all part of a cunning plan to reduce friction losses , only 3 wheels in contact with the track, 2 driving, 1 steering!
Best regards

Hmm, I like the idea of both steering-wheels being in contact with the tarmac!

BRILLIANT PHIL

As you know, SuperBee was one of the inspirations for my V8 MGB.

And now its re kindled the MGB Marque back on the 1/4 mile to continue what you started all those years back

Respect!!

Nah!!
Its more fun this way Chris

Since I tweaked the rear suspension I dont have to add much steering input on the launch now. Even though she is still cocking one leg ??

I forgot to add that I jhave a bad brake bind that we discovered on the second run on Sunday. I coasted in drive down the fire yp lane and popped it to neutral at about 10mph. It stopped quite quickly on its own??

I havent had time to find out which brake is binding though. I'll have a look over the weekend.

Glad you liked that one Perry. Here is one I did earlier - if you are Really trying you can get the bootlid to open!

A torque-tube is definitely required......

Hi Chris
In my case I found that the rear axle mount for the top link on my 4 bar had broken on the drivers side - and I then went for stiffer rear springs, so later on the car was launching like this

There you go Perry - it can be done!

But not easily with cart springs on a stock chassis

This was supposed to have been my PB attempt but something went wrong so I had to do my PB on the next run.

Can anyone spot the problem in this slo mo vid ???

Loose nitrous line ? seems to be something going on by the bug catcher ?
EDIT. is the bug catcher fully opening ?
