[Fot] Torque Reaction Arm for the TR4

[N197TR4 at cs.com]

"You can share this information with the list if it helps. 

Dick Stockton uses the round motor mounts as well as your torque 
reaction arm (mounted on the opposite side of the factory mount so it 
works under acceleration). He has had no fuel foaming issues running it 
in this configuration.   Bob"

Dick Stockton's FOT Alter Ego reports that Dick uses the Torque Reaction Arm 
on the opposite side (Driver), instead of the passenger side. This will work 
from full acceleration and makes sense.

However,  I think the factory put it on passenger side to limit the first 
action (rotation of engine) under severe braking. This limits the full travel of 
the engine, from left to right at the top of the engine, when you come off of 
the brake and go directly to full throttle. (Visual engine rotating from 
extreme left to extreme right at the top)

The ultimate solution might be put the Torque Reaction Arm on BOTH sides of 
the engine. I may consider that for mine. 

Note: Since the TRA is normally in no direct contact with the frame, it will 
not transfer vibration to the float bowls.

The same concept will work with the TR3, but it needs different dimensions to 
fit.   Someone asked about this

I have never tried it on a TR4A frame.
