9 Cylinder Engine

[YLD-CHLD]

What does it use for cooling?

its in the thesis in a lot better detail

its called a dry sump :sorcerer:

I think he was wondering how you oiled a piston that was upside down.

its called a dry sump :sorcerer:

but how would the dry sump scavenge from the bottom of an upside down piston thats moving?

and for my earlier post, yes it might pull well from 4500-10000, but how often do you rev to 10 grand on the street? just like rotaries, severe lak of low down torque (again i would need to see a dyno graph, but this is my assumption)

wow, why not a 13, 7, 19?

quite unco i must say, i dont know what to think of it

Don't know enough about determining engine balance to be sure, but given that 6 and 12 cylinder engines have very good balance maybe this guy has worked out a way to make a very smooth 9? Don't be too quick to judge.

guess the firing sequence would work out. tying to read all the thesis LOL.

interesting....

with an internal catch can!

three turbos! 1 small, 1 medium and 1 large

its too easy!

526hp from 3 litres is pretty impressive,

but, then again, a 3.2L race NSX car will do that with only 6 cylinders...and probably best not to mention to them how much power the 3L V10s in F1 cars were making before the V8's came in (which already make nearly 700hp from 2.4L)

i love the way we all criticise because it is not within the bounds of what is considered 'normal' engine configuration

what would have happened if 'they' were as harsh when the Wankel was designed, and he didn't keep going with it?

and if we go far enough back, the internal combustion engine itself?

tall poppy anyone?

Seems pretty 'normal' in the age of W12 and W16 engines

But as a pure race engine, with no emissions standards to adhere to (or mass production origins), it doesn't make huge power for it's capacity and revs, but is still very impressive for a scratch built motor designed on a limited budget.
