Crankshafts are cheap. Its that little piece of paper that costs all the money. And no, its not about liability or volume. Its about Lyc/Cont simply forcing GA to pay whatever it wants,Only issue I see is that as everyone should know, the 1st flight is Tuesday.
BTW, let me know where you can buy a 300HP aircraft engine *crankshaft* for under $10k, and you'd have my attention. ;-)
You can get quality forged, heat treated 4340 SBC cranks from Callies or Lunati for well under $1000. Similar quality to what's in a Lyc.Good crankshafts are not cheap. A good Chevy crank truly airplane quality is about $2500. Not some cheap Eagle junk. Lycoming only makes about 1500 new engines a year now. That ain’t much. A couple of times Lycoming farmed out cranks. Nice big hairy ADs. One a judge ruled that they could sell no new engines until all the customers that had a bad one was taken care of. Took Lycoming a year to make new cranks before to sell new engines. This was about 2003. 50% is cost to build 50% is for lawyers.
No doubt. One thing we chose was to remain all OEM stock. No after market cams. Yes, we contacted several manufacturers. As GM offered their factory Hot Cam, we felt comfortable going that route. And it was not terribly expensive. I think you can get one from GM for around $700 or so.You can get quality forged, heat treated 4340 SBC cranks from Callies or Lunati for well under $1000.

Just for comparison, the complete FWF package from Titan will run you close to 60 big ones.LS3 is a 300hp+ motor.. it can make a bag of bricks perform like a PITTS
Looks like a FWF package.. $50k or so IIRC
Get it down to $10k and you have my attention.
Ok. Let us know how much is enough. That will give everyone a target to shoot for. In our case, we have a max 430 hp available, due to rpm limits, with a max gross operating weight of 2250 lbs. On an airplane that was designed around a 100 hp engine. For my purposes, that is more than enough. And that power is with an engine that is complete factory OEM stock.Depends on the RPM you want that 525.
... And no, 525 is not enough.
