Spoiler II does 200MPH!
Michael Callahan makes his goal!
We have done several articles about Michael Callahan and his exploits with his Spoiler II. For several years he has been keeping his car as stock as possible while also meeting the Bonneville requirements for safety. His most recent goal has been chasing the 200MPH mark. Remember, this is a stock body street driven 1969 Spoiler II!
Michael recently achieved his goal. Below, in his own words, is his brief story of how he achieved this remarkable goal. I have also included some links to our previous stories about the path this remarkable milestone was achieved.
200 mph at Bonneville is finally a reality!
Since my last trip to Bonneville in June (2024), where I ran 187, I have made a couple of changes to the Mercury in hopes of maybe going back to the salt this year. I changed from a dual plane street intake manifold to a single plane and added taller rear racing tires. Luckily I was able to return to Bonneville and run at the World of Speed event this month. On my first pass on Friday I ran 193. The salt was dry but slick and with a lot of vehicles to run, you could only get in one run a day. For my next pass Saturday I decided to increase jet sizes in the carburetor and advanced the timing a couple of degrees and also blocked off the front grill to help with the aero. Driving more aggressively I was able to reach the magic 200mph at the three mile. That was everything the old Mercury had that day. After all the years of work and many trips to the Salt Flats I had finally accomplished my goal of going 200 on salt in my street car! Thanks to everyone for all your support thru the years.
