5 psi of boost on 3 mains
I hope its a good crank
I would be cautious about how long and how high you spin that baby.
But I will say it’s a cool design

Actually if you build it right with good parts three mains will hold 23 pounds of boost for some time. 5 pounds is nothing for the stock assembly to handle I know from a bit of experience. The Flathead platform is really strong with three mains. The running temps will get high well before you could ever hurt anything as long as the air fuel ratios are a bit on the fat side.

All I can think about is the conversations you must hear about this twin turbo flattie seen at a cruise night! Some must be hilarious! Someone not in the know seeing a flattie can really bring up some great stories but can you imagine a flattie and twin turbos?!?!?? Lol!!!!

Really cool setup btw and I, like others, would love to hear/see it run!

Well not everyone is afraid to spin them up Im not alone in how hard the Flathead can be pushed and survive. However the majority of people are just happy having a nice running engine with little interest in pushing them hard and theirs nothing wrong with that.
