The duration of the cam when parked (not active) is simple numbers, but with VVT it is not a static thing, and people’s eyes glaze over when I explain combustion phasing in detail, so here’s a quick animation:

Whilst the engine is building torque duration is skewed to early induction, and a deliberately short expan…[Read more]

Yes thats the best, others approximate BSFC.

Thus bro sez ut bihst:

Once engine oil pressure is greater than the preset pressure of the (air side) of the piston, it is forced back and the (oil side) chamber is filled with a fresh charge of oil. So once set it is automatic.

Yes it is wired hot from the ignition circuit, via an installed oil pressure switch on the oil bypass adaptor plate

which powers a hydraulic solenoid valve.

So everytime before cranking I pause for five seconds or so to allow the pressurised piston to inject a few litres of oil through the system at a head pressure beginning around…[Read more]

Have you tried PipeMax?

Yesterday I saw a Delorean coming the other way along the Bracken Ridge Wetlands area… a most unlikely and welcome sight and freaky because today is the day Marty, Doc and Jennifer arrive #BacktotheFuture

So yeah #science, iPhone, NetFlix, VVT and shit but time’s up where the fuck is my hoverboard? #BacktotheFuture

Nah not N2O, it’s a pressurised oil reservoir that injects directly into the lube circuit when pressure drops below 35psi.

It works well for pre-oiling on startup and burnouts and racing circuits generally, a poor man’s dry sump because is an auxillary damper utilising the existing oil pump.

I say mostly dry sump because the sump is still…[Read more]

Even the “always 85%” ethanol is only ever 81%-83%, so I ‘splash out’ on high grade alcohol – e95 – on weekends:

For perspective, the difference between ULP91 and PULP98 is seven RON points. Take that difference, multiply it by 3x … this juice is 120 RON… yes that’s .

No very straightforward, one plug connector off, swap in the space glow afterburners!! 

OEM VFII beauties!

Not Gawler, no. Barellan, NSW.

That Space Pirate look…

Funky.
