let me start by saying I don't know as much about this stuff as I would like so bare with me if this is a stupid questing. I'm still learning

I will soon be building my first engine. From what I've leaned, a stroker would be a good choice for my purposes since it will be going in a super beetle (heavy) and I live in LA (stop and go traffic).

Is an 82mm or 84mm to big a crank for my purposes? If so what would you recommend?

82mm crank with chev rod journals and scat I beam rods will require minimal clearancing of the case.84mm reqires more clearancing of case and cam. Yes, it is an excellent choice when used with 90.5/92/94 bore size.Lots of useable power.

Awesome. Thanks for the feed back. I'm glad to hear it cause that means I can take advantage of that price.

It's no bargin if you end up running hot in stop and go traffic.....

You would be way further ahead with a stock crank and enlarge the bore.

I'm talking money wise and practiclity.

There is no reason for a stroker engine to run hotter than a std. stroke engine if it is properly designed and carefully assembled. All things being the same, stroke has no effect one way or the other on engine temps.

I'll be sure to tell that to my buddy who's currently running a 2110cc engine in his daily driven '68 Bus. No issues to date with excessive temperatures or overheating. It's all in the combination.

I second the poster above me.

Cool...let us know if it arrives looking like the other one in this thread (forged with the business end of a claw-hammer).

I don't think electrickery works that way

This is pretty funny........why did Berg go to Sweden for the steel to build his crankshafts? Is China going to Sweden for the steel for there crankshafts? The stock VW crankshaft is make from 1045 forged steel. The E4340 crank is very strong, but does not have a big spread between the yield and break. There is no flexible. Don't worry about me, I have 2 84mm Okrasa cranks.

In the Mini world, crankshafts made from EN40B (S cranks) are considered to be the toughest, wonder if it's worth looking into for a VW race crank.

Sorry to bring up an older thread, but we sell rods and cranks from China to the Volvo community. They have been really good so far. This is in 2500-3500lb cars with 300-600hp/tq turboed 4 and 5 cylinders.

I'm sure we could get the same rods and cranks for VW's for the same prices as CB sells them for, but we are a small business that specializes in Volvo's only. I have bought single sets for friends with other makes.

Prices for VW rods and cranks are really cheap. We sell Volvo rods for $100 a rod, CB is selling the VW H-beams for about $62.50 a rod. That's a big difference, but I'm assuming there is 10x the volume for VW rods versus Volvo rods.

I'll check into the VW pricing just out of curiousity and report back.
