Chamber Rework for Improved Efficiency and Power

[@SRDmotorsports]

Here’s my dad’s bug he has owned since 1981 ! kzbin.info/www/bejne/qmameIprrdWkjrcsi=FQFu1Eg3EX89tLRc

This thing is gonna make some jam when you're done with it i just know it! Love the knowledge that you dropped as well, it's alwaya appreciated

[@SRDmotorsports]

a good coffee cruiser indeed 😎

[@vwdarrin]

nice work

[@SRDmotorsports]

Oh whoa! Thank you sir😎 always check your stuff (just almost no type4 here)

[@avomarkarian6187]

I would go with 90.5 I am Bulding a 1914cc engine with 94 mm and I have a 044 old stock cb heads I bought 15 years ago still needs porting and polishing

[@SRDmotorsports]

That’s a possibility… it’s just I remember my old 1679 beat a local 1776 so I’m not always worried about displacement 🤣

[@magicmaizie2015]

How important is it that each chamber is the same?

[@SRDmotorsports]

Yes definitely… that’s a must… I will cc’ the chambers when the build happens as it would depend if it’s gonna be fly cut for an 88 thick wall or a 90.5mm piston/cylinder 😎 So it is very important actually

[@Ek3_8888]

Sir, what do think if b18cr head bore the combustion chamber to 86mm same size with piston 86mm for b20 block. Is it any benefit from it? Ofcoz it will drop the compression right? Or any advantage for doing it

[@SRDmotorsports]

No need cuz if u look at the chamber the valve seat has extension to the chamber to guide flow so removing that makes everything else junk and how about GSR heads? They never get chamber bored doesn’t mean they flow bad So the question is why do it

[@Ek3_8888]

@@SRDmotorsportsmaybe people want to make the size of gasket matching with size of piston bore? Or maybe it can make tuner to do more advance timing since it will improve the cooling efficiency of the engine?

[@SRDmotorsports]

yeah depends on the builder and tuner preference just too much deshrouding also makes for a bad discharge coefficient

[@Ek3_8888]

@@SRDmotorsportsok sir I just wonder why they doing that😅 thanks for info btw

[@SRDmotorsports]

@@Ek3_8888 I’m not sure actually… maybe it looks good? It sells? 😂 welcome and glad the info is good for you 😎

[@magicmaizie2015]

Anyone else see meerkats?

[@SRDmotorsports]

where

[@magicmaizie2015]

The combustion chamber looks like a meerkat 😂

@@magicmaizie2015 oh now that u mentioned that! I can’t unsee it! 😂
