Questions on 6.0L LQ4 build
So I'm getting ready to tear down my entire block and rebuild it I'm pretty sure I'm going to run a all forged 418 or 421 stroker kit! After that however I'm still bouncing around ideas..... I really would like to run a Magnusons MP 1900 supercharger kit thoughts on this kit? Also I have never built a supercharged motor before and I understand the with forced induction motors you want to run less compression.... But how much less? This kit produces 6psi of boost. And would I want to adjust compression with the pistons dome/ flat top etc. or in the heads and cam set up?

I would run the TVS 2300 with that many cubes. Usually people shoot for 9.5:1 compression on boost motors but if you are only running 6psi, then you could run all the way up to 11:1 compression safely. Also, if you are starting with a LQ4 block, I would do a 402 or 408 set up.

You should start doing some searches for blowers and stroker motors on this site before you start getting parts. 1st off I would not try to get those cubes out of a Lq4 block and second that 1900 is not a big enough of a compressor for those cubes. You won't see a 2300 kit on their site but if you contact a site sponsor that sells Magnachargers they can set you up.

408 is as far as I would push it, LQ4 and LQ9's have not had the greatest of results when it comes to longevity with a 4" stroke. As for a 418 or greater you will have to go to a even longer stroke, if you are dead set on higher cubes then plan to use a different block like a LS2, LS3 or a LSx.

Also with running a supercharger is there a boost target range I should be looking for no more than? No less than? I want to be able to notice a difference without pushing it too far
