Time for the M140i addition to the library of cold starts.

M240i poppety bang cold start.



iPhone mic cut the second pops for some reason.

Yet another reason why my next car absolutely will not be bloody hybrid.

You still got the Porsche?

I shall do a no glow-plug cold start so everyone with a wanky 4 cylinder petrol can appreciate a good flattery start.

Dave!

iPhone doesn't do a great job here as its quite bassy but thought I'd post this anyway



Need to sort out a proper flyby vid with the bypassed rear silencer. Watch this space.

Found an instagram page of all cold starts. Lots of diesels in stupid low temps but lots of cool stuff too eg

My old V10 S6

155hp per litre n/a cold start and abrupt stop....I love the way the super lightweight internals make the engine stop the instant you hit the kill switch

This engine is over 20 kilos lighter than a bone stock K20.

Sounds smoother than I expected Dan...that yours? You not finished that yet!? but please, not the "bone stock"

Still want to own a V10 at some point, assume that's standard exhaust @tim ? always loved the long high-pitched noise starters make on the big engines.

That was especially for you lot, I can’t stand ‘stock’ or ‘bone stock’ either

Yes it’s mine, it’s almost finished, honest….

Smoother than a more conventional race engine would be due to the roller rockers on a Honda engine enabling cam profiles you can’t achieve on a tappet, which means extremely fast valve acceleration enabling you to reduce overlap but still achieve 15.5mm of lift. Hence it still ticks over quite smooth despite making over 330hp at 10k

Yeah full bone stock standard exhaust

I did one for my 86 a while back with my normal talking voice at the beginning for context (using a mic with fixed audio gain)

Steady idle that, with what sounds like a 100g flywheel

Flywheel is just over a kilo, entire flywheel and clutch assembly is 3 kilos - its a twin plate 5.5" diameter setup which meant it needed a thousand pound starter motor with a drop down gear to reach it, as i've got a single seater flywheel setup with a starter in the standard position rather than mounted on the back of an inline gearbox like they'd usually be.

Have some flat four air cooled rattle, excuse the legs
