[Fot] Weight Reduction TR3-4

[Barry Munson]

Amici -

As I have proceeded through Barnie's - 1959 TR3A -  evolutionary process
from a derelict barn-find to a vintage racer over the last two years, one of
the initial questions that I was faced with was related to the issue of
weight reduction. The question of how much and where could I reduce the
weight and remain compliant with the requirements for originality of the
majority of vintage racing organizations, while not compromising either
safety or performance, was forefront in making decisions. So things like the
addition of fiberglass components, changing the frame to a TR4, increasing
the width of the fenders or the addition of flares were not considered. What
I was looking for were areas that I could substitute alloy components for
stock iron ones, use of components that were available on later models of
the TR3 line and offered weight saving options. Over the last two years I
have been able to reduce the weight by 104 pounds simply by acquiring
bolt-on parts. Of course knowing what is available, its source and cost has
been the key and I have to thank many from this list for that knowledge.

The 104 pounds was achieved in the following major component breakdown:

Engine - 61.0 lbs

Chassis - 11.0 lbs

Front Suspension - 16.0 lbs.

Rear Suspension - 16.0 lbs.

In addition to the weight reduction that was achieved, many of the
components offered additional benefits in terms of safety and performance.

 

I have prepared a component by component table showing how and where this
reduction in weight was achieved, however it is much too long for team.net
therefore if anyone would like to receive a copy please just ask and I will
forward one immediately. I can also supply the source and cost for any of
the components. I have checked the archives for such a compilation and
couldn't find one - that doesn't necessarily mean that it's not there..
