Don, The fuel distributor can be modified to pass more fuel with out
drilling or cutting or modifing the control plunger in any way. I have done
it with several 930 Turbo's and the process yealded a 10 to 15 HP boost.
Take a look at the pricing on the web site.

Prior post:
"As with the turbo cars, it leaned out
horribly on the top end. Any of these solutions really exceed the
capacity of the stock fuel distributor/injectors."


I was talking to an authorized Bosch mechanic with regard to my solution to
the 'lean at boost' problem. What I do is inject windshield washer fluid in
liberal amounts onto the turbo impeller whenever I am in positive boost. It
cools the intake tract as well as adding fuel to the fire. As well as it
works it would be nice to not need it.

The mechanic suggested modifying the Bosch mixture control unit by removing
the plunger and machining a little more taper into the plunger such that it
flowed more fuel at the higher air flows encountered at boost. Seemed
reasonable to me but before I attempt it I was wondering if anyone on the
DML has any experience with the process. This would be a irreversible mod to
a very expensive component.

Thanks,
