Turbo; JH or PL?

[rfkellner at snet.net (Rick Kellner)]

The attached link describes, in their words, the proper way porting
should be done 'with calculations and a good flow bench work' and the
results that should be gained.  I found all the responses informative
however; one specific to porting and the use of a flow bench is located
about 7 pages down.  The pages are separated by a line across the page.
Again, all were a good read.  Rick.

If you want to find it directly, do a find on the word 'bollocks'.

I fully agree with David.  Unless you have a flow bench, you stand a
very good chance of doing more harm than good when you start removing
metal in head ports.  Port-matching is one thing, but changing the full
port cross-section is an area where few of us know what we are doing.

  Some folks love doing this sort of thing, to me I have never felt
confident.  I know that it takes a lot of consistency to get each port
the same pot to pot.  I know even better than porting it a certain way
gives specific gains, and I know that I don't have a clue what is the
best for each engine.  I sent mine off to Fumio to get the results I
wanted, bankable power.  I still don't have that motor in the car yet
though.

  A quick google if the internet found this.

  Not bad and it looks fairly easy. I am going to try this on the old
head of the 8v first. Test the tools and how stable my hand is. Any one
got a better link?
