When I heard 'Any idiot', I knew you were talking to me! Always enjoy your videos, Mike.

Thanks for the INFO.

Excellent information,  thanks.

Great info! Thx Mike

Cool man thanks for your input

Like always great advice my first build I following your advice and that little monster is 15k miles and running strong
Thanks

I have 2 - AS 21 cases. Sitting on my bottom shelf in the back.
Saving for rainy day - ha ha !!! Both have never been machined. All stock - might have to sell to buy groceries if things keep going up !!!!
Excellent video as always - thanks for the info.

Your awesome. Thank you for sharing your experience. Totally rad. Love that you are so willing to help all of us.
Thanks bro

where 87 came from is back in 1970  what they did is instead of giving you new p/cs they would use a old school piston expander and then there was it looks like a drill press machine that was a cyl bore hone and then stick some .010 rings on it . then they had green end wrist pins that were over sized and hone the bushing in the rod and the piston to match , they charged 8 bucks a piece but when you could get new VW brand p/cs for 10 bucks a piece    WHY  a 87 is a 85.5  .010  over sized . now they make them new but back in the day they were used .

Sir--  I have seen your videos in my feed for a while but hadn't watched one until today.  That's when I discovered you think like I do.  So I wanted to ask a few questions about my engine.  I don't know how where to go to ask, so I'll ask here.  I have assembled a 1641.  I used stock heads, a CB "Cheater" cam with 1.25 rockers and Mexibeetle springs.  I have an EMPI pea shooter style exhaust, and Weber 40 IDFs.  I didn't do anything with the heads because this engine was built using 85% of parts I already (I only bought the cam, rockers and valve springs....and the exhaust).  I don't have any idea what the CR or deck height is.  Just whatever the factory values would be.  Based on things you said in the video I'm commenting in, I'm thinking it would be worth my while to pull the heads, and, perhaps, replace them with something that will give me more CR.  I've used the CB engine size calculator a million times.  With 87mm pistons and the stock 69mm crank, if I shoot for 8.25 CR, and deck height of .050, and can obtain the desired CR with a CC volume of 50.  I would actually like to get to 8.5 CR but I'd have run. 045 deck and 47 CCs.  Is 50 CCs reasonable?  Seems like suck a small volume to me.  Thanks in advance

Mike, what are the reasons for not building a single relief case if you are not building a performance motor?  I have seen people build them to 1904 or even bigger

Please build a slow turning VW engine which has a cam giving it's best torque at 2700 rpm.

Cool running

Low compression

Aluminum engine case

Good flow in/out

I gave the 1.25 Rockers to my wife for her dune buggy I rebuilt.  It gave it a little more pop.  And in that fiberglass car it moves good.

Hey Mike, this is Mark from Montana. Curious what you would recommend for building a 2021 for a camshaft.

What octane do you run with 8.25 compression?

Does a guy need the expensive lifters to go with the cam? Everyone says to replace with the cam, do you buy stock ones?

Is the ingle 110 good for bug or bus ? Thanks

Good stuff.  I did a 40 HP awhile back for my '62 that I wanted to have a complete stock look yet pep it up a bit.  I put in an Engle 100, 83mm pistons and rejetted the 28-PIC carb a bit and the difference was huge.  That thing really pulled hard and I could drive it on the freeway and hold 70 mph no problem.  Everyone told me I was nuts but it really worked out well.  The cam is key......and cheap.

Thank You for sharing with the VW community.  The thin wall 87 mm and 92 mm cylinders are a bit risky = hot running... A 1904 is a good choice due to very little case clearance work.  The nice cylinder heads available today save a lot of money. Having custom head porting is money. One quick point for performance is with a higher lift/duration cam you can bump up compression.  For my own engine I will run 9 to 1 in a bug with a 110 cam. In a bus, 8.5 to 1 (realizing a bus engine has a shorter lifespan 😊

And im available Sundays and Mondays :)
