Dirk,kreeg laatst het volgende mailtje binnen van Andy van Performatek.
I've been working on a new product that may have some interest for
you. in addition to all the new drive line services Performatek now
offers, i have started development on an Aluminum Flywheel for the V6
engines. This is a part of the standard tuner performance parts
arsenal that has never been available to the Alfa V6 community.
Weight with steel ring gear is projected to come in under 10
pounds. The original (3.0L) flywheel weighs close to 27 pounds!
By going to an aluminum flywheel, rotational mass is cut by some 63%
and inertia greatly reduced. the engine revs much more freely and
more of its torque is free to spin the rear wheels. These types of
weight savings can never be matched by shaving the original, (in
fact, these should be half the weight of a shaved unit) and are much safer.
As far as i know, no one else offers one, and now i know why! The
built in imbalance in the flywheel, required by the engine's V
configuration, makes it much harder to design and build a proper
one. You either have the special equipment and knowledge to make
these or you do not. Most flywheel makers do not. They make zero
balance flywheels (as in 4 cyl Alfa engines) which are a much simpler
proposition. I have found a supplier who specializes in flywheels
like this, and he is willing to entertain the small business that
servicing the Alfa community brings - not a trivial issue!
We used a Milano (75) 3.0L flywheel as the base for the design. It
will work with any V6 engine in a dedion chassis. For 2.5L engines,
a special spacer is required, and 3.0L flywheel bolts are required as
well. The imbalance weight differs between the 3.0 & 2.5 flywheels,
but the difference is well within the range of what a balancing shop
can deal with.
First engineering has been done, costing developed. I am turning
production on this week.
They will not be inexpensive, however, i think pricing will be within
"reason", and the performance gain will provide good value. It is a
one time expense that will provide benefit forever, never wear out or
need rebuilding.
The first buy is the worst because there is a significant amount of
engineering cost to amortize. I have enough committed buyers now to
make the proposition financially viable (at least i am not likely to
lose too much money!), and so i am proceeding. The more that commit
to the first buy, the better i can make the pricing. If you have any
interest, please contact me soon, and we can discuss further. email
or call 508-655-8079.
Thanks.
