roller cranks are awesome. great for fast spinning motors, but if too much horsepower is squeezed from them, *BOOM*

From what i have heard of them they arent too good in a high rev motor. there are a few vw performance books with info on them.
best off with a c/w crank i reckon.

Before you put a bid on Ebay.....do your research!!!
From all records alll I hear is BAD news about these things....as Dave said, "WOFTAM!" (For the unenitiatied Wast of #$%^*&^ Time and Money!) Not a good investiment when building a high HP motor.....

You have been warned!

they are apparently just the thing to rev out a vw to around 7k. However they won't use keyways and as such are very prowen to damage if you load them to quick. Therefore they are usless if you plan to drag/street race.

You're reffering to "roller bearing" cranks then?
They were used in the very early carrera's only to free up the friction between bearings and crank. They then fitted a carrera motor with a normal bearing crank and found there was much more resistance when turning it by hand, but when running (oil heated and circulating) they were making identical power to the roller but alot less fragile.

No QANTAS actually its an old saying there. We had another one as well COTOS see if u can work that one out we did shift work there.

The other main problem with these cranks nowdays if finding someone to align them if they have been pulled apart to replace the rollers.

A better puchase would have been the

Dave,
that's the same brand crank as the one I have in my engine now, except I got mine for nuffin!

Peter Keegan ran an 82 mm SPG roller crank in the 70's in his supercharged Beetle, It ran 10 second 1/4's back then, He had no problems with it.
This thing ran on methanol and up around 20lb of boost,

But these days there is no need to use one, with all the good plain bearing stroker cranks around.

well, heres the thing. This is an old crank. they do work well. They are made for revving higher than a stock crank. but they arent that good at holding alot of horsepower. The reason for buying one of them is to build a period correct motor with the good stuff. It may not be completely up to date by todays standards, but Id use one in a hearbeat. In fact. Im building a motor with an Original Counterweighted EMPI 40 horse crank, Big bore 40 horse pistons ( 83 mm) Original EMPI cam, Original Serg Erson Rockers, and 40P11's mounted on OG EMPI manifolds. It may not be the fastest, or the most powerfull, Or even the most reliable. But its a kick ass motor to build. And Its the right motor for the car that im building.

Scott, that sounds like a nice old skool combo.
I want to build a old skool 36 HP motor for my oval one day.
Counter wieghted crank, blueprinted and balanced, ported heads, Arbarth exhaust and twin 28's.
Hopefully would put out the same HP as a stock 1600.

Mine should put out about the same horsepower as a mild 1776. Its alot of work to get everything correct and safe. I ended up having to send the case out to get cam bearings put in it. But to build a good oldschool motor, you can under do it, or over do it. My manifolds have small ports in the back that you could put Nitrous nozzles in, but hell no, thats an expensive motor to blow up. Since i have so much invested in the motor, tring to squeese every horse out of it is too dangerous. But, i am going to push it a little harder than i should. I am trying to get as much out of the motor, without compromising it. I have 6 inch parabolics velocity stacks for the carbs, to free up some air movement, 6 Volt 200mm flywheel that has been lightened to 10.5 pounds to help it get to speed a little quicker.
Grey 57- building an old school 36 would be sweet. Myself and a few others have been kicking around building damn near the same motor you describe. we have also been talking about getting some 3 barrel weber IDA's and cutting them down to one barrel, and put them on a 36 horse, just to say that we did it. But as of now, we know very little about those 3 barrel IDA's.

Scott, what I would really like to build up is an Aussie only hot up kit using twin SU carbies and a Lukey Muffler.
Aussie Old Skool.

There is a really good article on this in an old Aussie car mag. If some one has it, would they be able scan it and post?

Yep they are the ones Scott. Way kool I reckon. But way rare and probably way exy too.
They say that a dual 28 carb kit will make as much power as a judson blower on a 36 hp motor.
Cant wait to put that to the test :thumb😀

I reckon those Old Blowers have been around for So Long - they'd have to be a period accessory as well :- although the
judson is a bit small, I'll just replace that with an 80's style one
