Mains 1, 2, 4, 5 will be at 0.0018" and Main 3 at 0.002", Rod clearance at 0.002"
H22 88mm bore BC rods
Opinions?? I was told these numbers because of the possibility of adding supercharger

 

boost does not have an effect on bearing clearances as far as I am concerned. Piston to wall and ring gap, of course. the biggest factors for bearing clearances, IMO, are peak operating RPM as well as the type of oil and viscosity used.

With that being said, those clearances are fine unless you plan on spinning 9-10k rpm......which, IMO, wouldnt be smart with the m92 supercharger to begin with. They are good enough at being heat pumps at OE rpm ranges.

 

Even if I decide to stay NA and maybe trade off for a shot a n2o

 

speaking generally, yes, those will be fine. But again, depends on what you want out of the engine, what you are going to be doing with it...etc. engines get built different depending on intended use and how wild the engine is setup as well as other aspects which daily engine builders use.

 

Sweet thanks. Think I'm just gonna trade my sc for a 100 shot n2o kit. I'll only need the NA dd'ing all the time anyways. Been reading so much my eye ***** hurt. And I got other responsibilities as it is. That's why all the questions lol. I only got a couple more days to confirm cause crank and rods are getting balanced and then once that's done it will be out the door to my place.
