Ok, naturally you balance all your components together.
though i think it is impossible to balance 4 stroke inline 4-cyl by just balancing the parts since the pistons coming down will be moving at different acceleration than the pistons going up. (due to the geometrics involved) so piston travels different length near TDC than BDC at same crank angle.
It seems to me that most engine builders eliminate the balance shafts, but i'd like to know more about the theory why it is done. The rotating mass is not that big since the weight is very much near the center of the shafts, they do run at 2x the speed which might cause lubrication problems on a high rpm machine though.

every little bit you can shave off counts.
And if the balanceshaft belt snaps it will also kill the timingbelt.
and most people don`t want their timingbelts to be snapped
Please post a Quadruple and Quintuple plate Titanium flywheel clutch for a Evo. 
This thread only gets more insane.

Hi,
The turbo is for the prostock Linde Markus project.
We are about to finish the 2000hp project, i will update sortly.
Next post i will show to u the best and lighter flywheel from billet or titanium for 4g63 suitable for most known 3.5'', 4.5'',5.5'' and 7.25'' clutches on the market. 2-3-4-5 plate systems capable.
From 750lb-ft capacity to 1780lb-ft.
Lekonna, no balance shafts. All the parts are 0 balanced it self.

Also, what A/R turbine housing were you using?
Oh my F*** . Im saving up for a set of your cams for my 2.4 gtx under 7500 rpm setup. Very glad to actually see some pics of how thorough you guys are. The holes in the flywheel look like the intake ports of the cylinder head. lol
