The 67 Sonett of Tom Donney should by now have the new land speed record for class J/GT. Yesterday they ran 108.66 mph and today ran a return run of 110.336 mph for a combined run of 109.514 mph. This doen't sound too fast but this is being done with a 750CC two-stroke engine.

This is the second engine so far this trip! Saturday one of the volocity stacks fell off causing the engine to run lean and burn a piston.

It's official 109.514 mph. They rebuilt the fuel system yesterday to compensate for the 90+ wheel hp. Bigger lines and bigger needle and seat for the solex carbs and istalled a differant head to raise the compression to 16/1. They were waiting in line to run and a giant storme blew in and shut the track down for the day. Plan is to get in line EARLY this morning and attempt to raise the record again.

Tom stated that the pits are 5 miles from the starting line and that he sat in line testerday for his record run from 7:00am untill 11:00 waiting because of the amount of cars attending.

Awesome. I bet that is some mean-sounding popcorn.

Would love to see video of a run. Assume he has at least an in-car GoPro set up?

The engine has to appear stock and everything on it has to have been available from the OE manufacturer either stock or assesory. The block is a 850 Monte Carlo that has been resleeved and resized to 750CC The carbs are from a Lancia but were available from saab sport and rally in the 60's The exhaust is a home made 3 seperate chamber system and VERY loud.

The bar has been raised!!! They ran 116.099 into a head wind for a record of 115.691

They said now it's time to realy play. The record has been raised and now it's go or blow for the motors. They took 3 blew one on Saturday so that leaves 2 more to destroy.
