    DIY crankshaft balancing with an oscilloscope

    What is the real purpose of crankshaft counterweights on a flatplane crankshaft?

    Fun fact...I once cut a vw gti inline four crankshaft exactly down the centre - when viewed from the side, with 1+4 at tdc, and 2+3 at bdc. Big end journal bits weighted exactly the same as the counterweights. I could write about 10,000 words more on this but I'll hold off. All I'll say is...

    Press-together crank vs a billet crank

    Billet all the way... A press fit together crank is a nightmare to build up - At least I hate doing it... Something thats wire EDM'd, would be even moreso I'm guessing. Keep in mind too oil way drillings in a built up crank...you're going to have to have a lot of grooves, 90deg drillings, and...

    Piston to wall clearance, during operation.

    Still sticking to my word on this guys - as a stubborn Irish man. Modern materials, I've never once seen in anything non round upto 105mm, billet or cast, upto 13,500rpm in production engines - way above in F1 stuff. I've even seen the lathe gcode run... Bowing out of this thread now as I gave...

    Piston to wall clearance, during operation.

    @CWB1..very expensive Mitutoyo equipment... I feel some of your advice in this thread is old wives tales to be honest. Ive stood beside at least 50 cnc lathes making motorsport pistons, and the same making oem items in cast - they are round - I assure you - please stop spreading false info...

    Piston to wall clearance, during operation.

    @CWB1, have to disagree with your last comment having measured very accurately probably 1000+ petrol road car pistons. From 999cc vw units, to 500hp Bmw V10 items. All are ''round'' just tapered towards top. To even go as far as F1 pistons, which Ive had a few through my hands..these are also...

    More F1 part teardowns,

    Formula One Engines - Tech Videos of the Rare Engine Bits

    Started a new youtube series two weeks back - there was a bit of demand to see these parts ''live in person'' so to speak - have written many tech articles on them in the past. Hopefully the videos will bring a bit of life and scale to the parts! Ep 1 Pneumatic Valve Spring...

    Race car Dry Sump system starting to fail

    Tmoose, yes...they all suck air, however poor collection entry or windage causes serious oil aeration - not normal, along with volumes of air - normal. See vid below, tanks wont de-aerate if case is severe and must be done with another centrifuge section also built into pump...

    Race car Dry Sump system starting to fail

    The scavenge sections are normally sized to the pump - however, sump design can cause collection issues or windage. Did you change sump pan design in the past? (Ps...it may not be that at all..just shooting the breeze as its odd..) B.

    Race car Dry Sump system starting to fail

    Scavenge too big - aerating the oil? Pump pullies tight and not spinning at high rpm? Brian,

    SF Tower settlement Part II

    This is a silly question, but if it has sunk 16" how are all the entrance doors still working or if the entrance doors and thresholds are also sinking with the foundations - surely there would be a very noticeable ramp/step down into building? Explain! Brian,

    Carbon fiber fuel tank

    ''Fuel systems in F1 (and in every other serious racing class) are heavily regulated to avoid teams compromising driver safety to increase performance'' 'we are developing the carbon fiber fuel tank for vehicle application' Which is why you shouldn't use one. Brian,
