How much porting are we talking? I'm thinking of standard engine, rebuilt,
and porting would be with standard valves. OTOH 170BHP would be plenty and
would keep costs down - if I were heading for 200 horses, I think I'd prefer
the 1.8T route...

Who remaps the VW ECU by the way? I was assuming it'd need a custom ecu in
the MK2 or run off the existing Digifant setup, but I've not done much
research yet.

Yes, it was.

"Mr. Pot, Mr. Kettle would like a word with you"

Despite what you say, unless you have measured the power on a bench and
then in the chassis for that particular car, the 'corrected' figure is
pissing in the wind.

However, it wouldn't have been good for your business if this was
publicised.

I think it's just a basic job cleaning up everything and then three angled
valve seats, you don't want to open the ports up too much and lose torque.

Yep, don't waste your time with the 16V if you want over 200bhp, just go
straight for the 1.8T.

The corrected figure has nothing whatsoever to do with engine or chassis
dynos and obviously both cannot be compared. Ans as I already stated you
cannot give a flywheel figure on a chassis dyno anyway.

The "corrected figure" only relates to the absolute atmospheric pressure and
temperature and both are corrected to a standard pressure of 1019mb and 20
degrees c. I t has nothing whatsoever to do with chassis or engine
dynamometer comparisons.

A chassis dyno is just as accurate and measures as ir says rear wheel Hp
CORRECTED to a standard pressure and temperature if you want it to. Or not
if you dont but thats useless.. This obviously includes all transmission
and tyre losses as actually happens on the road.

An ENGINE dyno does exactly the same thing and it too is corrected in the
same way. Unless you have a specific reason not to do so. In which case just
like a chassis dyno you instruct it not to bother.

Correction factors have absolutely nothing to do with the difference between
the two types of dyno or measuring "flywheel" or engine power on a chassis
dyno (which is and will remain impossible)

Do you get it yet???

Prey tell me why not?
What EXACTLY would you publicise??? This should be fun...
