Why no boosted strokers?

X air makes Y power. When you force the air in, the actual CI of the engine isnt much relevant. Smaller CI lets you run smaller bores, shorter strokes, which increases relative piston/rod combo strength due to pin placement and compression height, as well as thicker potential cyl walls.
For a given sized turbo, you'll move the power curve down and decrease spool....and increase back pressure the larger you go. Ran a boosted 383, excellent off boost power and spool, went up to 15 psi on 93 pump gas no issues. Doing it over again I would have saved the money on the added cubes and turned the **** on the boost controller lol. Regardless of stroker or not, whether or not it lives comes down to whose tuning it.
