A shameless image thread for the enginephiles

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Uhm... what intercooler?
My thoughts exactly, it's just a carbon tube with an air filter attached.
That's the air intake. The "intercooler" is (isn't) the piece of aluminium tube running across the engine bay in front of the engine.
my bad, yes just a nice looking intake plenum, no visible intercooling present.
The impossible often has a kind of integrity which the merely improbable lacks.

Why would they ever not run an intercooler? Looking at the pic it's not like space is a constraint

Not needed, its an alcohol dragster setup.

An engine with what's left of a corvette attached:

I am pretty sure that is the kinsler ITB setup. I have been really good if anyone would like to get one for me.

One unusual feature on this one is the axial-entry, tangential-exit on the turbine to accommodate the PTO.

Also, there's a bellows joint right at the turbine entry. The turboshaft seemingly quite long if directly connected to the compressor i.e. one continuous shaft. Is such a large high-RPM device with a flexing region in its middle a unique achievement?

High res image here for inspection:

More of that sweet single-channel low-restriction intercooler.

I remember this! It was on NR750 and 125 HP from that displacement was kinda big deal in 1992.
Hardly.. unless..if by epic, you mean epic fail.. & Yamaha had a 125hp 750 on test - in 1972..
I did not write 'epic' i wrote 'kinda' - as it was totaly new architecture and the engine from the get-go was at (or near) the top for that displacement (not talking racing bikes here or something that was on test bench). The biggest fail on that engine (IMHO) was that it was too heavy.

And, please tell me as I was driving lot of bikes at a time and cannot remember myself, which bike that was sold that year made 125 hp from 750 ccm in 1992 'epic fail'?

Huh? Dunno quite what you are trying to express there.

In 1972 Yamaha had shown their GL 750 4 cyl EI 2T roadbike, but chose to to offer the design for sale - solely as a racing machine, & sold a dud 750 4T twin as the streetbike, instead.

Image

The NR Honda effort was an "epic fail", both as a race bike, & as a production streetbike, no question.

A better intercooler.
With vortex tubes ofc.

How much TQ does it make though?

Could have a much shorter pipe if they'd simply drilled a clearance hole through the radiator. Running it through the headlight seems like an odd choice, you'd have to run sealed beams to make sure headlight fluid doesn't get sucked in.

An intercooler without a turbo? Interesting...

The GN Spider II's 1920s unique chain-driven overhead-cam 4v per cyclinder 90º V twin (since any links appear to be broken in this thread)

I read somewhere that it's effectively dry sumped too. If you can call it that. It uses pump-driven squirters instead of the gravity fed setup it was originally designed with. It's still a near total loss oiling system though.

It's one very sporty tractor.
