Cat Diesel Land Speed Record Fantasy Car


Recommended Posts

This is a land speed record car that "could have been but never was", based on components available in 1973.  Power is two Cat 3406 6 cylinder diesels, conservatively rated at 550hp each but capable of much more.  Target speed is 300mph, which I think would have been possible, IF you could find a driver crazy enough to climb in.  Here's the specs:

Displacement:  1786ci  (29.2L)  
HP: 1100 @ 1800 rpm
Torque:  3700 ft lb @ 1200 rpm
Weight:  ~20,000lb
Cd:  .40
Frontal area: 8 sq ft

This was one of those projects that got totally out of hand, as you can see from the build thread here.  I had recently finished another fantasy LSR car (Quicksilver), and this one was forming in my demented mind even then.  The main components started life as an AMT Ecto1A and a Revell Kenworth W900, with an extra engine from ebay and lots of mods and bits from the junk box.  Paint is Createx, Wicked Golden Yellow/Wicked Orange with 5604 Gloss Top Coat.  "Caterpillar" lettering is dry transfer, "C" decals are photo printed.

Call me crazy, but I find it very entertaining to imagine I'm behind the wheel of this monster with seven tons worth of diesels rumbling behind me.  I may do more detailing on it someday, but I'm done with this one for now - except for the fantasies!

Very creative build! Your body creation looks awesome. I like the color! Top notch work!!

Not to take away from your excellent build, those are 3406 or 3406A engines, the 3406E looks quite a bit different and wasn't available until 1993.


You are absolutely correct!  1973 was the first year for the 3406, first post corrected.  Thank you!

Many thanks to all for the kind words!  This was a fun build that took WAY too long.  I'll think twice before narrowing and modifying a body so drastically again, I think it's time to start my Tamiya Jaguar Mk II.
