Are there any differences in the compression ratios between these pistons? The last of the pre HE engines had a 10:1 compression ratio and are these pistons available to buy anywhere?
Would like to see a discussion on piston wear and suitability for reuse. I have a set of used 9:1 UK pistons I'd like to use to replace the 7:1 US pistons in my pre-HE engine. None have severe damage as seen in the examples you showed. What do I measure and how?
@@thecampchaoschronicles9567 Apparently it is, but only (for me) if I'm using a different than std audio device - I took the suggestion from @handhwiegman8115 & changed my output device so.. something on my end though I don't have this issue on any other videos - and AFAICTell, stereo works fine and is in balance on the default device and I've double-checked the plug insertion. IDK what's going on except if I switch to essentially "mono" sound - like via the monitor's inbuilt speakers, the narration comes through. Otherwise about 5 - 10 seconds comes through in just a couple sections of film. I'll keep working on it and figure it out. Intersting TWR just machined OE E type Hepolite Pistons. Will you side skirt coat those Omega pistons & give them a top thermal barrier coating? I never thought about the wrist pin being offset on the Jag Engines, but it now makes sense with a to-the-front directionality to the pistons. I'd like to know why it makes the engine smoother but less powerful. If the cylinders themselves had been offset to the outsides (instead of the wrist pins) theoretically more power could be captured from TDC (because of the rod angle offset) than directly in-line (the opposite of what you've noted happens with the wrist pin offset.) The hashtag d4a (Driving 4 answers) channel has a good short animation explaining offset cylinders. I wish we had a real extensive documented piston PN list with pictures even if many were NLA.
@@ferrariguy8278 Piston offset makes the crankshaft reach TDC before the piston does. I may do a Tuesday extra about pin offset. The original pistons aren't going back in, we have new omega supplied pistons. The specialist the client is in touch with thinks it may have been an early development engine.
I'm wondering where that is documented b/c the block was done in the West Yorkshire foundry, and one would think the heads would have been done there or at another UK foundry as well. All machining and assembly is of course on video right through the 6.0L being done in the UK.
The West Yorkshire foundry story btw is an intersting one 1846 to 2004 (closed) with buyouts and name changes from 1997, but was the premiere UK engine component caster for numerous firms for decades...

There's always the sun shining at Camp Chaos.
Very interesting I always wanted a talk on these engines pistons

Super cool information!

The TWR notes i have show the CR to be 12.19:1. We had to have the new pistons made.

IDK if it's just me, but the music track is there, but not the narration.... Might need to check this one & re-upload if it's not just me Robert.
I checked and it all seems to be there.
try to listen to both Left and Right audio channels, or try Mono. Sometimes Bob’s narration is on one of the two channels.

He V12 drop vave seats and suck because they have India Made heads valves and pistons....earlier Pre HE v12 are the only war to go Jag V12!
