I believe if John wanted to and wanted to spend the money, he could build a 900 HP engine.
He has built up the knowledge BTDT to do just about all the work to do so.
I expect he'd have to contract out some machine work.
He can see and hear the air, lol so I expect all porting would be done by John.
BTW My heroes have always been cowboys. lol

At this stage in his life I don't think we will ever find out and I actually think he found his niche, and a good one at that, of making simple, reliable, moderate power and putting that into a light car......easy recipe for running on the cheap with less wear and tear on things
