This is another great video about heads that touches a little more on technicals. Actually the whole series is a great watch when you have time to ****.

Stay twin turbo. Those borg Warner’s aren’t too big for two? What would you do for wastegate? I was looking at Precision 11910 wondering how I would mount it and 3 boost references on it have me wondering what for. I don’t know Jack about reading turbo maps but definitely don’t want to something out of efficiency or surging.

Well, what are your real goals? BorgWarner EFRs are available internally wastegated up to 74mm.

I want a set good enough for power just over 700 awhp but capable of up to 850ish full send. Idk if it’s realistic to have a one and done turbo setup but that’s what I wish for. Instead of a big single what about a compound turbo setup? Had me wondering bc doing a larger custom turbo for the front would have plenty of room….but can’t leave the smaller one on the rear? So then rather than one single turbo do a compound setup.

Just need to keep it as simple as possible really.
