RE: JE Pistons finally arrive :-)

["MLP" <mlped@concentric.net>]

Marc -

Thanks for the information on the J&E pistons.  For rough comparison
purposes, do you have any idea what the weight of the OEM pistons were, as
compared to the J&E's 380 grams?  I know were probably talking different
sizes, 81mm vs the J&E's 82mm but... that should be close enough for guess
work on the effects of the changes.

I'm assuming the J&E's are definitely forged as opposed to the Audi Stock
pistons (my guess) cast?  In addition to strength, I thought another reason
to go with forged was supposed to be their lighter weight?  Any idea if you
original pistons were cast or forged?

Finally, does J&E give you a cylinder tolerance to bore to, or is that
something your machine shop decides for you?

Thanks

Mike P.

The pistons are for an 82mm bore.  Each piston weighs 380 grams.  I also
got lightened pins at the same time, but I don't remember the exact weight
of those.  Some other miscelaneous bits of info:

Top Ring:  1.5mm
2nd Ring:  1.5mm
Oil Ring:  4.0mm

Pin Dia:          .866in
Pin Length:      2.500in
Wire Locks:       .063in
Inv. Dome depth:  .475in

The cost breakdown is as follows:
                         Ea.    Total
Wire Lock Chrome Si.    1.50     15.00
JE Premium Pin          22.50   112.50
Ring Set(Total Seal)    94.93    94.93
Pin Fitting              4.75    23.75
Pistons                100.00   500.00
                                ------
Total                           746.18
+shipping               10.27    10.27
                                ------
Grand Total:                    756.45


If it is any help, the Job # of this was 193763.  They should be able to
pull up the specs from that number...

HTH
