[Fot] Why is the TR250K so fast?

[quicktr4]

the reason the tr250k is so fast is the talent behind the wheel. tony is a remakable driver and can make an also ran car run upfront. not that the tr250k is an also ran.the standing joke in the pits is if you want to take 5 seconds off your lap times just have tony drive it.the tr250k is a very good car very neat to see it run.

  Having read all'y'all fun stories about the Glen, the 6-cylindered TR250K
  and Sam Halkias' car were phenomenally fast, even faster than
  Bill Warner's and Tom Kreger's cars (which are phenomenal in their own 
  right).  I'm going to make the assumption that all the drivers were of 
  god-like ability, and so any differences come down to the cars.

  From top-secret spy photos, I think I understand why Sam's car is so fast.
  I suspect that Sam's motor is producing way more HP than anyone else,
  and I think I have heard that Sam is running a TVR rear tube sub-frame
  as does Dave Wingett.

  I don't have as much access to spy photo's of Kas's car, but what I have seen
  does not explain the success of this car.  Yes, I understand that the aerodynamics
  of the plastic body and weight is a significant advantage over the steel/plastic of 
  the racing TR6s.  I assume that the TR250K shares the same wheelbase and track
  as its production cousin.  I am also assuming the TR250K is tube-framed, and thus 
  more rigid. I am presuming that the engine is the same as Kas ran in the Kastner-Brophy 
  TR250/6, so is not offering a HP advantage.  Photos show that the front suspension of 
  the TR250K is "stock" TR, except that I cannot find any bracing at the top of
  the coil tower.  I have no idea what sort of voodoo is going on at the rear end,
  but I suspect that it has unequal-length A-arms.  Anything has to be better
  than the Triumph semi-trailing arms.

  In summary, I'd say the reasons why the TR250K is so fast is due to:
  1) Lightweight aerodynamic body, rigid tube frame;
  2) Some unseen voodoo of the "stock" front suspension;
  3) Rear suspension voodoo, including rear disk brakes.

  Of course, what I really need is more spy photos so that I can attempt
  to copy some of the more esoteric top secret engineering.
