SPG Roller Bearing Cranks? Good for the Street?

[Fasterbrit]

I have an 82 mm SPG crank that is in very good condition with zero twist etc. I am thinking of using it in a hot street motor that will not see strip action. I realise there are issues of the crank twisting when heavily loaded on slicks. What about using them on the street? Anyone have any info or stories to share? Ratto? Thanks, matt

Has the crank been pin'd - as each layer gets pressed, all the newer ones were pin'd at each layer - if it has you will have no problems with it. I twisted on old 69mm crank after a 8000rpm pull, but it wasent pin'd. Have built 3 or 4 with these cranks and have had no problems. The only draw back, Heavy.

This might be a little bit OT, but how to or who can pin a SPG crank ??
I also have a very fine 82 mm SPG crank without pins in each layer and
would like to get it pin'd, any pictures or link would be very much appriciated

Funny you guys should ask cos Rob (bronze manx+deano van) is having an 82mm SPG rebuilt AND pinned by Gary Holznecht - the original builder of lil Snort 

I have his email address if anyone wants it 

I also have a NOS 82mm SPG linned up that I will be sending over to Gary soon - I have heard that once you drive a roller crank its hard to go back cos they are soooooooo smooth

[ian c]

or have i got the wrong end of the stick again ??

There's a roller-crank motor running around near me, in the most unlikely-est of cars.  Got to drive it once, its a pretty good time!

Tiny pulley and Solexes on "GENE'S" manifolds.

The only draw back, Heavy.

That's what aluminium flywheels are for

I'm running an 82 SPG roller in my bug and had no problems whatsoever!!

I did get told when I built the engine though to never use it with slicks. (It's a street car so no problems there)

I also got advised to not run a compression ratio of over 8:1

The advice was from Geoff Thomas (from Autocavan) who was the sole person to import them into the UK back in the day apparently.

Your right about the slicks/track thing BUT I was think more like 10/11:1 for my 2180 monster

Well I just played it safe to be honest as it was originally a 2nd hand chuck together job from an old VWDRC car but with better heads and bigger carbs.

Long term plan was to eventually build a proper engine with a forged 82 and higher ratios but I thought I'd start mild and build up to mental when I was richer! (Hasn't happened yet)
