the above link is to a very large page of description on valve lift profile design ... we hope you enjoy it

Prof Blair

thank you VERY much Mr. Blair for all the great info you provide here

keep it coming Sir

Is this forum still open, and if so how do I get to it.

Professor Blair died last week - there is a tribute on the Prof Blair and Associates site!

I tried posting the link, but if you search for Prof Blair and Associates you will find it!

What a loss. The world is a lesser place without him

Here's the link to the tribute :

I'll leave it to individuals to read it if they like but the closing line is worth sharing here.

RIP, Professor Blair!

The tribute was very informative. I really enjoyed learning about some of his many accomplishments.

rest in the very peace you deserve SIR.

thanks for providing the link to his tribute. all motorcycles entusiasts, lovers and mainly those interested for design, tuning or simple to compreend how a engine really fires are devasted by such notice.
one of the hardest and greatest accomplishments made by him was his books. super complete in every aspect, outsanding detail for the covered aspects keeping the books relativetely small, very affordable, with humour and most important very compreensive language for every people! be it a doctored mechanical engineer that want or need to increase his knowlege about engine design or the uneducted (school studies wise) person that just want a outsanding reading and loves motorcycles.

no better tribute can be made to SIR GPB and his legacy than to quote him:

''The Last Mulled Toast

A Grand Prix race is very rough,
the going's fast, the pace is tough.
The four-stroke rules the world of cars,
in bikes it´s the two-strokes that are the stars.

Now, why is this you´d have to ask?
The rulemakers you can take the task.
For the intake air never needs to question,
"Is this the right bellmouth for my ingestion?"

The designer of both must surely know,
or else his engines will all be slow,
unsteady gas dynamic trapping
by right and left waves overlapping.

To model an engine is algebraic simple.
You sit on the gas like a veritable pimple,
solving the maths the waves to track
from valve to bellmouth in the intake stack.

At the inlet valve you scan induction,
count the air that´s passed by suction
and just as the valve would shut the door,
you get a wave to ram home more.

In the exhaust it´s furnace hot,
for the modeller ´tis a tropic spot.
Exhaust waves reflect but do the job
of sucking out the burned gas slob.

Some time ago I wrote two tomes
on two-strokes, including poems.
It seemed only fair to tell those with cars
that black-art tuning is best kept for bars.

This book informs the four-stroke tuner
what I wish I knew decades sooner,
as Brian Steenson followed Agostini
with my exhaust on Mick Mooney´s Seeley.

The pen´s both strokes have now been told.
My writ is run, I´m pensioned old.
While I may be ancient and time is shrinking,
only Dei voluntas can stop me thinking.''

SIR Gordon Blair,
1 November 1998

He was my mentor, friend and colleague - a great man, who told me that he felt lucky to have been able to spend a career doing something he loved, which was more like a hobby to him!

Helio Lucas, with the greatest respect, and I'm not sure if maybe you already know this, but Gordon Blair was awarded a CBE (Commander of the British Empire) and not a KBE (Knight of the British Empire) by the Queen of England in 1995 (in tribute) and so is not "officially" a SIR!.... although I figure he probably still is in your eyes!
