I'm guessing if you have to ask..... you cant afford it! lol

No pics yet! Would be interesting to see some.

1/4mile in 13.2sec @ 111 terminal on 15psi

pics or it isnt real

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

I'm wondering how they mount the 4th and 5th bearing?

Unless they don't, and just counter balance but i would think you'd get some flex then.

Be interesting to see a picture

the extra bearings could easily be 'bolted' into the crank case of the block from the sides. Consider that the original three bearings take for arguments sake 33% of the load. Now fit two extra bearings, they all now carry only 20% load. That is more than half the load the original bearings deal with.

I'm not sure how the cam would work around this though.

I'd suspect the extra journals simply float ?

If everything is designed and balanced up properly, then I guess they dont need support. The crank is likely over engineered anyway

I seriously doubt it!

I wonder if they had this crank when the Dart was originally raced in 66

they have gone about a slight! problem and over engineered it, thay would be better off using the money and making a larger displacement block with crank and rods........... come on Mr swift tune

theres a market for sure in that

Nick only goes for what is allowed in regs, a larger displacement block isnt an A series anymore, a new crank in a standard block is still as a series as a different profile cam, rocker ratio or straight cut gearset.
Can of worms again?

I seriously doubt it!

Flexible rules?

If something is worth doing, it's worth doing half of.

not great because i dont have scanning ability

So are the 2 extra journals actualy bearing surfaces then or simply floating? says in the article is uses 5 main bearings or this just a terminoligy thing and im being a picky bastard? interesting non the less

David.

Look at the picture Brett posted. It's a crank designed like a 5 mains one, but wears only three. For improofed counter baöancing. I think the '5 main bearings' sentence is just a bit missleading :)

[X] nail here for new monitor

Even then I wouldn't hold your breath!

So, forgive me if this is a stupid question, but given the revs which they're talking about (8000+), what advantage are we talking about over a well prepped steel crank and rods (given the likely cost) - reliability and life expectancy in a race application presumably?
If the major selling point were the smoothness that it mentions I'd have to question VFM.

thats the same arrow crank that MED are selling IMO

So basically they have developed a new crank

1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.

Looks clever.

If something is worth doing, it's worth doing half of.

a well prepped high reving 'normal' configuration crank will suffer from torsional vibration as a result of the lack of propper counter balancing, which could mean failure of the bearings or the crank itself, not to mention the loss of power as a result of the vibration itself.

If you ever get a chance to look at the super high reving motor bike cranks, you can clearly see that they are far from light, since they have excellent counter balancing which is one thing that allows them to rev to 16k+

Heavy counter balanced crank and super light flywheel is the way to go
