5.4
You're not going to get any more stroke out of the factory 5.4 , their isn't a 6.0 / 6.2 unless you are getting the 6.2 motor from Ford or any Ford affiliated party. Some would bore then place slightly bigger pistons and a three angle competion valve job. Their is potential in the 5.4 3v Triton modular motors like to make power and a good built one loves boost. On the turbo or supercharger. Either way need the cooling to handle. I'm thinking procharged.for my set up . I've looked at several 5.4 built for 18 psi boost to 25 psi boost . I good built 5.4 3v with these numbers can put you in the 650+ hp range. Easy starting in the $5k to 15k price range
I don't know half as much about engine technology as you or the other person you are at a flame war with, but why would anyone recommend keeping the stock displacement instead of boring it out to 6.0L - 6.2L if you plan to use a supercharger? Could you not increase the displacement and run more boost to bring more power or am I missing something? Not trying to sound like a dumb ***, just a realistic question.[/QUOTE]

Stave Lake in Mission, brother. That's where to go. And when you're done let me know, I'd like to swing by and check your beast out!

To answer the question...
Bore has nothing to do with how much boost an engine can run. It's all about compression. An 8:1 engine will be able to handle more boost than a 10:1 engine. Keep in mind that rods and cranks will usually be the weak point in forced induction setups. What good is a big boosting turbo and big stroke/bore if the rods are going to fold in half? Also remember, 15-25 psi is very different depending on the turbo size you run. Cfm will vary at the same boost levels depending on the turbo size. For example, I have a lot of experience with the srt4's. 15 psi on the little stock Mitsubishi turbo is COMPLETELY different than 15 psi on a 50 trim or a gt30/35r...
