Hello Net;
I am not going to try to add technical expertise to this discussion, just
impressions. In the rebuild project for my KR's engine, my #1 plan is to
turbocharge the Type 4 that I am putting together. I am not as interested
in normalizing as I am in adding a little horse power. I do plan on
lowering the 8:1 compression. My decission to do this is based on my
experience with an engine swap in a Mustang that I drive. The car started
life as a 2300cc engine with 88 HP @ 4600 RPM. The Ford Thunderbird Turbo
Coupe engine that I installed uses the same basic engine, with some
differences, namely the heads and crank, added a turbo and boosted the HP to
145 @ 3600 RPM. All I want is to boost my VW, which will be 2366cc to 100
HP. The boosted Ford engine recommends that 93 Octane fuel be used for the
maximum boost. I already use 100LL in my KR and should have enough octane
to safely boost without detonation. The Ford Turbo system used a vacuum
switched waste gate to control boost if 87 octane fuel is used. I will use
a manual waste gate to limit boost.
I welcome lots more discussion on this subject.
