Alot of rods carry surplus material over the cap. If it's properly butressed around the bolt, then it makes it stronger, but most aren't and have a neat stress raiser created by the rod bolt counterbore; like these "kit car" replica rods:
Also the reduced piston and rod mass of my designs reduce stress. If you take the peak inertia of a Wossner "Kit Car" piston and PEC rod at 9000rpm, mine won't see that until 10,000rpm on the same stroke. And because I target high torque figures over using revs to achieve power, my engines tend to be limited about 500rpm lower than others. The resulting inertia at the rev limit is about 27% less. That's a healthy margin of safety, before you consider the manufacturing/material quality and bolts.

It's amazing the amount of sharp edges and vertexes you can find on some expensive mechanical components. really is shocking coming from some companies that must run these through FEA and just say "good enough"

I won't be saying the valve sizes I'll be using, but single piece stainless. The exact sizes I use aren't available as a direct fit, so I have to re-machine valves designed for other applications. I use various sizes according to spec, it's a fallacy that bigger valves equal more power, there are so many side effects at work that valves sizes need to be developed alongside the cam profiles, CR and chamber/porting/seat work to get the delivery you want. I don't use "big valves" as most people would; moderation is the key. Anything over the standard seat insert sizes means oversizing the inserts, and I don't like changing valve seat inserts unless I have to, it adds alot of cost and risk to the process. So most of my development has been based on valves that fit on the standard inserts safely.

Will do
I wouldn't go any bigger than standard inlet on a JP4 unless you really have a good reason to do so.

New set of pro race 1.2 wheels and t1r tyres have arrived, mainly for the trips to track days, ring trips and the odd show...
Also means I can now run my r888's for longer

Ment to say to you that one in the boot needs using or least un strapping, as making marks on tryes.
Work will resume on yours once I can get myn out as the trolly jack has broken and can't get car down lol and other jacks having new seals fitted lol. All steel ect should be here tus.

Nice work mark!!!!
This thread has being a pleasure to read from start to now. It's really nice to see the car is being built for the use its intended for. As well as sandy giving us a insight to how he builds the engine' with a eye for detail that is next to none.
Keep up the good work and look forward to seeing future progress.
