The most boring build you ever watched... 1385cc

[modok]

some 30% of flywheels are stepped now, so hopefully people grinding flywheels should be able to deal with it if they grind all kinds of flywheels.

Would be nice if the flywheel grinder has a CBN "wheel" instead of an regular grinding wheel. CBN wheel always keeps a sharp corner, that makes it easy to get into the corner of the little counterbore without enlarging it.
Pressure plate should fit snug in the flywheel so that it s centered and the balance is not thrown off.

The step distance should be between .827 or .835 depending what book you look it up in.

Cb cheater seems like a good idea IMO

Using the full groove bearing with single drilled crank is.....a good idea, but it isn't a requirement. VW didn't seem to care which bearing went with what crank.
Single drilled VS cross drilled and full groove vs half groove is.....like what is your favorite brand of oil. Everybody has a opinion, but generally they all work.
in the past I have extended the oil reliefs inside the bearings to be closer to 90 degrees each. Did it work better? not sure....but it didn't work worse.
doing this you might think to yourself.... Is the oil going to flow up this side of the groove in opposition to the way the crank rotates? hmmm so I did not extend the "leading" side as much.
Now I think I would extend the oil troughs in the bearing, BOTh ways so to be at least 90 degrees each, and add an additional hole to the leading side of each groove.
I got the idea from LS engines, and a discussion on speedtalk, besides just common sense.

It's not that having two holes in the crank is good, rather that the cross drilled VW cranks had a HUGE oil trough ahead of each groove. With so much groove in the crank you don't need as much groove in the bearing. But actually I think that was NOT best. i have noticed measuring these cranks they almost always have excessive wear next to the oil troughs, and that's interesting because generally cranks do not wear much on the sides. it's possibly a clue to what is really going on, far as HOW the crank flexes.

awesome! thanks modok. you answered my questions and then some. The Chinese went with a smaller cross drill on their crank. as noted on both the AA and empi crankshafts. idk about the rest but mine have considerably smaller cross drills.

btw do i have to re coat bearings if i cut a groove in them? i will look for that thread on speed talk. i found some interesting topics over although admittedly i rarely visit the site. after all, i do have one post

oh, and i FINALLY found an un garbaged pinion gear. except for that little knick on the side. its slightly protruded above the surface. how should i knock the edge down?

thanks

edit- ok damn thats a blurry picture. apologies

Just knock down any burr with a little file. Brass is soft, work softly!

[Chickensoup]

how about a pair of SU carbs from something like a rover v8 or a volvo? whats so special about these carbs besides looking cool and being simple? will they work just as well on a vw as they do on bikes and British cars? I saw some on a vintage speed car today and it got me thinking.

Thanks

Yes they should work just as good on a single port VW as they do on an MGB

BUT, it's only been done a few times, so, it's experimental.

You need a good set of carbs to get the engine running good before you do any experiments.

[Chickensoup]

yeah that sounds like a better plan. they caught my eye is all. i think if i were to try them out, id get a set of the 1 1/4 in throat size su's. which is 31.6 or .75 mm i think.

btw, are their any known "mods" i can do to the type 3 (32pdsit) carbs? i think i remember seeing people improving the flow of the passages and stuff like that one other carbs. i know way more about efi than i do performance carbs. of course jetting should need changing. i will study a diagram of the carb if i can find one tonight. thanks

wait a second... what if, i add a groove to the main journals before i have it ground? This is something i can do on a lathe right? thanks

I don't know how that is done.
If it is "turned" they must be doing something special to prevent chatter, or, I just don't know.

[Rome]

[modok]

Bushings IN now.
How much force.... to press in the pin bushings?
.004" press+ loctite, turns out, 3000lbs

Is the loctite completely unecessary?....probably, just tradition tho
it doesn't hurt

Honed to .0008" clearance, assuming a .866 pin. Alignment checked, 3 needed very slight correction. Checked the big ends, right at 2.2760" good.
Done

[evanfrucht]

Loctite is lube, lol

Well... atleast before it cures

Slippery when wet as it were

True, used sunnen pin press, about 1 second.
Loctite not recommended if installing the bushings with only "arm" power.

[Chickensoup]

YAY! thanks fir reaming them Mr. Modok. even before the bushings were installed the pins were a bit tight. Cant wait to see em. I got 700 bucks ready to lay down for this engine so mega progress isn't too far away in the future. Thanks again!

I didn't feel comfortable with the small box, so I used a bigger box, needed some packing material so I stuffed a blue book in there to help fill the space.

[Chickensoup]

Just as expected, the rods came out beautiful! A true work of art. Thanks Modok!

Gots me some hood core heads

32pdsit carbs

Nos german 83mm ring set

A 1600

And some body panels

Also, this book is dope Modok

Have to keep in mind.... the time it was written, late 80's.
Aftermarket parts were very limited, and the ONLY parts.... were new parts from the dealer, or totally blowed up used engines.


Gene at that time did not fully understand cylinder head flow ratios, or exhaust system tuning. The stuff about compression ratio is wrong.
The book used to take a lot of flak about the info that was wrong, but that's because A LOT of it was right.
I think.... if Gene had CONTINUED to keep innovating, he would be right there with us, or ahead of us, but that's not what happened..... instead GBE is still around but they build engines like they are stuck in 1990. Not complaining, just saying.

And it's slightly a shame that the book is out of print.
Last few years I rarely see anybody discuss if the "Berg way" is the right way or the wrong way.....you think we finally resolved all the issues?
GREAT!
But no, the real reason is the book is no longer available!

So now you've got he "old testament"
Someday somebody should scan that thing and put it on the net for history's sake, maybe it is your destiny, or maybe it isn't. i don't wanna

[Lingwendil]

If I could find a copy to scan I would! They are always expensive- too expensive to cut up to get the professional quality scans that slicing up the binding would entail.

A kingly gift, for sure
