Toward the end of my racing career, I started using lightened Wrist Pins (G=
udgeon Pins for you British.=C2=A0 Not to get too far off the track, but I =
always loved where the workshop manual describes the process called "Reamin=
g the Gudgeon Pin Bush".=C2=A0 Maybe it's just me, but there must be a sexu=
al connotation there someplace).=C2=A0 OK, back to the subject at hand....
My intention, of course, was to lighten the reciprocating mass in my TR-4 e=
ngine.=C2=A0 I found a guy in Quincy, IL who could have these lightened pin=
s made up for me, and I ordered 2 sets.=C2=A0 By this time in my career, I =
was only running 4 or 5 races a year, just enough to get qualified for The =
Runoffs, and The Runoffs itself.=C2=A0 I ran these in both of my engines fo=
r a few years, then I bought 2 more sets to replace them in both engines.=
=C2=A0 These are the pins I replaced, and therefore, they do not have much =
track time on them.
Externally, they are the same size as the stock wrist pins.=C2=A0 However, =
the wall thickness is only .87", compared to the stock wall thickness of ab=
out .161"=C2=A0 Thus the reduction in weight is considerable, with the stoc=
k pin weighing 143.4 grams, while the lightened pin weighs only 86.6 grams.=
=C2=A0 Multiply that difference times 4, and you have a total reduction of =
227.2 grams of reciprocating mass.=C2=A0 And the good news is that I will l=
et them go for only $25 plus shipping. =C2=A0 Anyone interested?
If no one is interested, I will put these on Ebay in about a week.=C2=A0 Th=
anks.
