[DeTomaso] Engine Bay Air Flow

[Göran Malmberg]

The force of inertia can be tremendous depending on the time we alter
its movement.
Bjorn Carapi experienced the same thing at very high speed but he broke
the clutch.
 
Yes, I remember that now, Eskalov was hard on gearboxes. Myself I have
some sort of 
“ in body inbuilt function” that makes me handle mechanical things in an
orderly fashion. 
But from a strict go fast standpoint, those “rough on things guys” may
be VERY fast
drivers. But remember, one has to get to the finish line in order to
win.

Esakov's problem wasn't exactly just 50 horses. It was that his engine
was already at 750 and he shifts gears like a drag-racer. Shock-loads
seem to be the problem up in this power region. Jr Wilson's monster
big-block also broke ZF input shafts by getting air above 220mph without
backing off the throttles, also shock-loading the tranny when the car
hit the pavement under power. 

Jr had split Holley Dominators on a Hogan sheet metal intake. That put
the float bowl vents in line with the roof, so instead of cutting into
the roof, he cut the decklid's top loop plus a short amount of the rear
roof and built a scoop that sat on top of the carbs, above the roof line
but quite a bit further back than Colin Haney or Gregg Esakov had. It
probably wasn't ideal but did seem to gather enough cool air to support
around 850 horses at over 230 mph without going lean. Interesting fact:
Jr tried EFI early-on but lost speed and burned valves, compared to
carburetion. Dunno what system he tried but it sat on a shelf in his
shop for years. Might still be there....

And the gentleman from AZ that did cut the roof on his GR-4 clone,
adding a NACA-duct-type depressed intake: wonder how that worked out at
speed? It sure looked good and apparently used the area in the cabin
above the console so no head-bumping on a lowered roof. But since I'm
incompetent at bodywork, its something I will not personally attempt.
Nevertheless, I enjoy all the air flow speculation. Now, if someone can
test some of these ideas and write an article for those who don't live
on the web, that would be ideal. Good luck- J Deryke
