F1 » Only physics could have limited V8s, admits Renault


A freeze on development and subsequent rev limits stunted the potential of taking the outgoing breed of F1 V8 to impressive levels, it has been claimed.

Since its birth the IC engine development was constant and continues, but there were two periods which are regarded as to have seen the biggest effort and focused concentration in the quest to extract the most power possible from the IC engine while overcoming the resultant problems associated with that quest, the first period is attributed to the Pratt and Whitney radial aero engine and the second period is attributed to the F1 V10 engine, while also on record will also be the FIA effort to stop and freeze the IC engine development.

isn't there two types of radial engine? one where the cylinders rotate and one where the cylinders are static.

ty, I don't think that sunny makes models, he makes real miniature engines. to me , a model is a static display reproduction, but a real miniature is one that works.

Taipan, in 1980 I bought a set of plans for a model 1/5th scale Pratt Whitney R-2800 radial aero IC engine from a MR Samuel Hodgson of Dallas Texas, at the end of 82 the engine had its first pop, it still takes pride of place in the home.
Richard the “round” IC aero engines are of two different types, the first one is of the Bentley BR1 and BR2 type, these where of the ROTARY type and not Radials, on this type the crankshaft is fastened to the frame and does not rotate, it's the cylinder block complete with anything fastened to it that rotates.
The other type is the RADIAL, with normal crankshaft rotation.

On the pup the prop set up was the same as two types of ROTARY engines were used, the French Gnome Monosoupape and the French Le Rhone which were both ROTARY'S.
The pup was the first to land aboard a moving ship.

sunny. nice to have a sensible debate about engines.
I was reading the other day, about a new performance engine (and I cant remember which engine.....I think that it was bmw....and they were saying that the pistons were steel. I was a little puzzled at that as I would have thought that they would be heavier, but apparently, they are light weight steel, and due to the fact that they expand at the same rate as the bores, they can be a much snugger fit in the bores, and can have slimmer rings and also smaller skirts. so I is far easier to produce to finer tolerances and improves performance of engines.
but it did make me wonder....were steel pistons ever used before in an ice?
