The VW factory built millions of engines with. There are far too many rocket scientest that simply insist the Earth will stop spinning and your engine will suffer a nuclear meltdown if you DO NOT have exactly. 040" deck height no matter what else happens in this world. It has become the absolute law here on the Samba that you must run.

Why is 0.040 deck preferable here? What is approx cost for machining? Would there be any harm in just keeping the. I will need to take the best shot toward removing 8cc.Maybe that 0.70 is enough. 01 cut would remove as it changes the actual volume removed with each cut toward the top. These are Chinese heads, unknown exactly then how much each. Since part of the area on the flat top is Already an opened part of the chamber, it cannot be included in the surface area to remove. Whoah! Now I see the error in my math logic. Posted: Fri 1:25 pm Post subject: Re: Flycut calculation math/machining verfication please 030, after removing the step, a problem? Confused here?! 090 cut is equal to the total cc mass needed to be removed, and gives the final 52 cc result? Is cutting the on flat. Measuring from the edge(?) to the top of a liquid surface will be difficult. 090 is based on 7.69cc, achieving the 52cc.+/. Im figuring the final resulting cc by just subtracting out the total mass calcuated to end up total at 52cc. Posted: Fri 8:43 am Post subject: Re: Flycut calculation math/machining verfication please 060" deck height.Īre you running a stock cam? 7.5cr is low these days. 040" deck will be better for multiple reasons than a standard. Trimming the bottom of the cylinders will also shrink your deck height and reduce the amount needed to flycut the heads. I did the before and after math on 37x33 AA500 heads and a. 010" cut per 1cc of volume is pretty close for new AA500 heads. ![]() Posted: Fri 8:40 am Post subject: Re: Flycut calculation math/machining verfication please 090 total? Not sure I understand why a problem, since still leaves deck? Would a machinist want to even take the time to recheck cc liquid several times between cuts?Sounds uber costly. 058 deck for squish? I guess I expect that cutting off the step is roughly. Well I will admit I suck at math, and this calculating is new to me, but isn't cutting that portion of the heads still leaving the. Posted: Fri 8:21 am Post subject: Re: Flycut calculation math/machining verfication please There are no stupid questions, only stupid people, It wont be extremely accurate, but from there you could adjust the deck a very small amount to compensate. This will give you the amount to machine the head. Ad 52 cc's of liquid, measure from the surface down to the liquid. Posted: Fri 8:13 am Post subject: Re: Flycut calculation math/machining verfication please Remember you can always remove more material but putting it back is hard! Be conservative and cc the heads after the first couple. I thought I'd read the rule of thumb is roughly 1cc per. I would not want to flycut that deep since its the combustion chamber volume, not the volume of the flat portion of the cylinder you want to reduce.

Thanks! So do I just find a machinist and say to. I don't imagine there's an alternative way. New heads came in at a whopping 60cc, but needing 52cc for +/- 7.5 compression (per CB performance calculator).
