[Shotimes] 7000RPM, Man , I'd have to spin a bearing

[Ron Porter]

Not true on the drag racing part. For the SHO (and other street cars I've
had), drag starts are no tougher on the clutch. Maybe with sticky tires, but
SHO dragstrip starts are even probably easier on the clutch than the street.

For the engine, you are not getting enough oil pressure/volume versus the
load being imposed on the bearings.

Granted, the overall wear is a minor issue. I worry more about the clutch &
tranny than the engine. You definitely CAN whack a pressure plate strap.

I have had cars with clutches.  Can't say as I have ever worn one out.  Drag
racing will ruin a clutch 100 times faster than engine braking.

If I don't get 150k on used motors and over 200k on new ones then I feel I
got screwed somehow.  I have yet to have an engine wear out before the body
disappeared.

Never had a mtx tranny problem in over a million miles.

If done at the right time and place and with finesse it will set the
chassis.

To use the compression of the engine to slow the car down does not use more
fuel.  The throttle is closed and you are making good use of the fuel
already spent.
