Triton build

Just working on this given I am on enforced vacation .... one for the Morris Dancing Pommy bike lovers

The exhaust junction seems a bit odd, both headers point towards each other and then bleed into the outlet.
Looks a bit restrictive

[Marc.com]

you need a little back pressure Geoff

[Daryl Jones]

The BMW M12 is considered to be the highest HP F1 engine ever, (1400HP in qualifying spec... ie. 3 laps 'til blow-up)

A little back-pressure must have helped (obviously didn't hurt).

The bright yellow at the merge shows point of highest pressure & temp.



Some might say So? This is a Turbo engine, it needs pressure before the Turbo! .

But looking carefully, we can see that the pressure/temp after the outlet of the merge, is significantly lower.
A valid reason for the tight merge here, is to generate Seriously Useful sonic wave effects in the header pipes and exhaust process.

The same engine was used, naturally aspirated, in F2.
Similar pipes & merge with a big megaphone instead of the turbo.



Probably valuable lessons we can learn from M-Power.
I know what I'll be playing with on the SL350 Flat-tracker.

They had a lot of problems with these engines until they used an old block.  New blocks would break but old work harden olds would last.

One show I watched on these BMW engines development said they used to leave the blocks outside to weather and rust up and that the engineers were encouraged to go out on there rest breaks and urinate on them to speed up the process.

So i've been wrong all along, BMW's aren't pieces of shit after all, apparently they're pieces of piss!!

      During world war 2 Rolls Royce used to put there Engines blocks out in the weather to harden and cure
      before they bored and assembled them said they lasted longer..

Yes you need back pressure but the other exhausts shown all have 'flow'
F1 engines don't have a header tube pointing straight into another header tube!

Left hand primary has one of those special cheater 180's as well..

Granted, I would like to see a bit more taper to the merge.

Its a bit hard to see from the angle of the shot, but from the diameter of the tube and how close they are (parallel) I would expect they are merging somewhere closer to 45deg. rather than 90. (or 90deg. included, rather than 0.)

Cheers, DJ.
