Just a quick note to thank everyone on this board for their input to my many questions over the past two years of the 924 Land Speed car build. We leave Wednesday for Utah and (hopefully) come back with the G/CPRO class record.
Rick
P.S. If I could figure out how, I'd post a photo of the finished car!

Would be great to see the car, if you can live with a swedish site try this:

http://forumbilder.se/

Super simple, no registration needed, upload the pic, then copy the link to here.

What are the specs for car/engine? I had to check last years results, and it seems like you need quite a bit of power to go that fast, i whish you good luck and hope the car runs like a dream

Regrettably my Swedish is non extistent, so that site won't do The car is a 1979 powered by a two liter NA that we reworked pretty significantly. It has a modified Turbo head with larger valves, forged connecting rods, custom pistons, two 50 mm Webbers, a custom exhaust header, is dry sumped and has a (no distributor) electronic ignition system. It has a compression ration of 15:1. The transaxle ratios has been altered to create increasingly smaller RPM drop offs off between gears as the speed increases (and air resistance increases). As an example, the 2 to 3 shift drops off ~1,500 RPM's while 4 to 5 shift loses only about 900 RPM's (we're shifting at 8,200 RPMs.) We're hoping for 160 MPH, but would be happy with 150!
Thanks for the wishes for a great running car!
Rick

Unfortunately while we beat the existing G/CPRO world record with a 140.19 MPH pass, the car developed a severe ignition gremlin on the requured back up run the next mornng and could only achieve 122.5. That meant we had to start over and try to repeat the first run. Regrettably we couldn't find the cause and had to throw in the towel and go home. The ignition box is now at the manufacturer to sort out the gremlin. Assuming it gets back in time, we'll make a run at the ECTA one mile record in two weeks. But Bonneville will have to wait until 2017!
