82 stroke, rod length?

[louisb]

Okay, I just picked up a new 82 stroke, VW journal, forged CB crank for a song. Time to think about rods. H beams or I beams? Length: 5.325, 5.352 (912 length) or 5.4? I am leaning towards the 912 length or the 5.325 length.

Rest of the motor will be:
44x37 Denham heads
48 IDAs
94 cimas
FK-45 cam

Mostly street miles, some track.

Any thoughts, suggestions?

Thanks,

I didn't think you could get a VW journal rod in anything shorter than stock length (5.4", 137mm)?? And I thought the 5.325" was only avaliable in Chevy rod journal? Either way, get H beams. The shorter the better

CB makes a 5.325 VW journal H beam:

I think Bugpack has a (12 length rod in VW journal as well but they are not cheap.

Yeah I don't want to go with a longer rod than 5.4. Ease of assembly is not my top concern.

Good thing ease of assembly isn't a top concern. Personally, 82mm VW journal cranks have been a bitch. Rod caps have always hit the cams in the motors I put together. You may find you'll need a smaller base circle version of the cam. A few 2276's with VW journal and Eagle H beams clinked the cam upon trial assembly, and yes they were clearanced on the back. I did an 84mm Chevy journ and had "more" room for rods to swing in Danny W.'s 2161

I'd watch "the shorter the better" belief. Yes a low rod ratio does make for a romper stomper motor, but just watch skirt to crank, rod-caps... there is a limit. Remeber you need .040"

5.352 on 82mm seems to always work with big heads and cam. Makes them "think" the motor is bigger than it is.

Having posted that, I will say much to Tom's chagrin I insisted on using my RIMCO Super Rods.     Mark Herbert's engine article on the old CLF really stuck with me.

JUst double check your rod big end to the underside of the oposite piston at BDC.

I know someone who is using the 5.325 rod with a VW journal on an 82mm crank.  Zach knows him better than I do.  He runs in the high 12s and drives it on the street or at least he used to.  Zach remember Travis's engine...?

Travis' engine used a Chevy journal crank. But you're right about the 5.325" on an 82, 12.63 was his best time, a true daily driver. He had to clearance the pistons skirts to clear the big end of the rods at BDC. The motor came out narrower than a stock engine, but only 9.1:1 as I remember. He pulled the car apart probably 3 years ago and hasn't driven it since.

hej louis

this engine is so similar to the engine I have in parts for assembly.The only Difference I would want to use 42x37 mid d ports,and 48 IDF carbs.

I have been searching for the wright answer regarding the rod ration and selection on few forums,and at the end I decided to stay with the 5.4 rod for the street.The piston skirts clear nicely on the crank with the I-beams .I-beams are more trouble clearencing,but they are alot cheaper,and the H-beam rods,they fit in more nicely,but you need to have $240 just for them 

I-beams are surely good to 7500,and they are strong with those 3/8 rod bolts.

which lifters,pushrods are you using?

Good question and I don't know. I would have to ask Jeff Denham. The heads are coming ready to bolt on from him.

Well it looks like this is a moot point now as the seller has apparently backed out. With no explanation they gave a partial refund of my money and now won't answer any emails. I have bought hundreds of things on-line and this is the first time I have been screwed. Oh well.

who were you  buying from?

[louisb]

I posted this on the samba but thought I would like it here so no one else gets burned by this seller:

ovalteen420 - christopher winkowski

Beware of this seller. He had an add up for a CB 82 mm stroker crank which I agreed to purchase. Made payment through PayPal for the amount agreed on through email. Later that day he did a partial refund of my money without any explanation. Now they will not answer any emails and they have not returned the rest of my money.

He uses the following contact information:

lebron.erika@yahoo.com
winksyota@yahoo.com (paypal account)

I'm sorry to hear this man.....In our hobby there are guys who would do anything to help us out and sell us good parts,but on the other hand there are some bad people out there.....

If you want a CB crank,get it from VWparts.net.If you need any other crank,I suggest Brothers VW Machine shop.
