~400bhp CSLs?

Hi Lawsy,

On the S54 Heads, its very hard to
make real world gains.

But I did Lightly port the exhaust ports,
de-burr, and Glass polish them.

At the same time I roughed up the Intake
upper and smoothed up the lower intakes a
little and again some small de-burring.

Triple cut the valves and made sure all
valve seats were flush.

Gains, maybe more than likely not.

I had the head skimmed 0.4 thou to make
true, but kept with std H/G as there
not exactly 'thick' to start with.

Regarding the posts of 400 BHP S54's on std CR or the even more
ludicrous 450 BHP 'Stroked' S54's just go
do the Maths, either all calaculators have
been incorrect for years or ''stroking'' the
S54 defies the rules of how an engine
makes Torque/Power.

Regards,

The Gorilla.
