94 bore / 76 stroke

Never mind. I noodled around and found out on an aircooled site that it equates to 2109 cc's.

Sorry if I wasted anyone's time. Sometimes I forget that a little searching can get a faster answer and not bother others.

Hi Bob,

There are lots of sites that give the cc of almost all the combinations of bore and stroke.  Just Google.  The formula is: bore x bore x stroke x .0031416. 

With your configuration, you've got 2109.69 or rounded off to 2110.

Thanks, Jim! I found that exact info on another site. Have a great day in paradise.

you can get to a cc by diferent methods, long stroke small bore big bore short stroke,med stroke&med bore.just going by the cc dosent always tell the tail. like my 1874cc.87 bore by 78.8 stroke. or my 2028 same basic motor but 90.5bore.and not all cranks are what they say they are, I have 2 78 mm stroke cranks, but 1 is 78.4 and the other is 78.8 not much different, but it does make a change in size&other aspects of the build.and about 10 cc's.

I would like to have a list of bore and stroke  and cc 's  combos from 1600 all the way to 2400 cc If such a list exist  i want to put it in my porsche note book that i used to build my speedster by..

scat, bugpack ,empi they all have it in thier catalogs.the scat cat has it up to 3048cc,but you can go biger. or you can go to CB preformance's site and use thier engine calculator & punch in what you want & you can figure cr,cc,deck,etc.

  if you figure out exzactly what you need the first time it saves on shippen, and have who ever you get the crank from ballance it(flywheel too) then it's usualy just a few things to get like cylinder shims after you find out exzactly what your stack up is& what you want then get the shims., but you need to figure everything as close as possiable so you can get the right cc heads for the cr to be where it needs to be. for me it's easy, I set pretty much everything up at zero deck&use a .040"(1mm) copper head gadget for clearance.but some heads have a step in them so that has to be addressed also to keep the quench down to .035-.045"(piston to head clearance)more than that and you are loosing a good amount of torque,power,mpg,clean chambers, happy engine.

You can also use aircooled.net's site for engine calculations. They have a displacement and CR calculator. Plus John is a knowledgeable guy who sells good parts. I like CB also. 

I usually use this one: http://www.chirco.com/tech_articles/?p=163

But a google image search for "vw engine size chart" will get you others.

The 76x94 combo isn't really popular because people usually buy 78mm cranks instead (why go with the smaller unit when you can have 2mm more stroke..). That said, it is a perfectly viable combination, and a 2110 is certainly big enough to make great power, no matter what the bore/stroke combo. It's actually a better way of doing it (for that size motor) because the 94mm bore won't shroud a 44mm intake valve (and interrupt flow) in a higher revving motor like the 90.5 barrel will.

the 78 will need a long rod or shorten the cylinders.so just go with 82 stroke.the 76 also needs a longer rod, or "A" pistons&a pile of cylinder shims. the shrouding wont affect a street car unless your spining it up to 7000Pluss rpm,you can also use a 42 mmvalve(witch I have in my 90.5 x78.8 motor) it's just like realastate, combo,combo,combo.
