Jeffrey Hoffman - Land Speed 240SX

Land Speed and Drag Racing

Get to know the Land Speed 240sx

Jerry Hoffmann, founder and owner of AMPEFI / MS3Pro and DIYAutoTune.  I’ve been a ‘carguy’ all of my life, and always had a knack for computers as well.  I worked in IT for about a decade and played with cars on the side.  Then had the blessing of an opportunity to marry my loves of cars and racing with my IT side, and started building engine management systems on the side, which quickly turned into a full time gig.  And never looked back.

I’ve done a little drag racing, a little more autocross, but by and large land speed racing has been my love after working with some of our customers out on the salt flats starting back in 2006 and helping them reach their goals and set several records.  After watching others successes and failures out at the salt for the few years I got the bug, started planning, and built a car.  Now if the salt would just ‘heal’ up so we could go racing there….   In the meantime I’ve racked up more land speed records than I can count in the car at the ECTA’s Ohio Mile event, 13 of which I/we hold currently.  Note that several of these records are running on larger engine classes—meaning we hold records all the way up to the unlimited engine displacement classes—with a measly little 3 liter engine…

Unfortunately the ECTA lost use of the airstrip we were racing on in Ohio, so we took 2016 off. They’ve still not found a new track but they’re working on it, so for 2017 we’re REALLY hoping the salt turns out to be a safe racing surface so we can go run the car where it was built to be run. Bonneville!
