Banjo/QC 4.11 Vs 3.54 Question?????

I picked up a 3.54 centre on the weekend for my QC, all I know is that people say it is the ratio to run in your QC, but I would like to know why?
Can someone explain the benifit of 3.54 over a 4.11??!!!!

 

411 has way less pinion load on the bearings on the later model QC'c but not sure what QC your running. It really shoulsd apply to all the QC's I would think.

 

Thanks, is that the only reason?
Its a NZ quickchange.

 

How bout some pictures of the old coupe! I want to see how shes coming together! i miss her!!!!

 

Don"t know about ratios but a couple of years ago I was in New Zealand and visited Derrick in Nelson and looked at his product,very nice very well made.I do not think a Culver city rear cover will interchange but his looks great with the Kiwi bird cast in it.

Anyone else?!

 

Use to do a lot of circle track with a Franklin QC and we used a master gear with a 486 gear instead of the 411 and at that time was the only 2 available ratios for the big QC that we knew of. The failures we knew of were on the 1/2 mile ovals and it seem's the pinion bearings went out in most cases. At thet time Bobby Allison was the Franklin distributor and he also recomended the 86 over the 11. I guess your use of the QC would be a factor as to durability.

 

Anouther thought that hasnt been mentioned, is the 3.54 for a street car gives you better ratio's if you are crazy about changing gears. With a 3.54 you can switch between hiway and normal driving ratio's by just flipping the gears from ratio's like 3.20 to 3.70 or so. Whereas a 4.11 will give you good street strip ratios like 3.48 and 4.86

 

You get less heat from the 3:54 , the gears in the back are bigger = lower speed less heat. old b-ville guy told me that.

 

That makes sense, as there would be less work for the gears as others have stated.

Thanks for all the replies fella's, keep em coming.

 

So thats it then, durability of the centre????
I was thinking it would have something to do with getting the most out of the gearing in a mathematical way.......hhhmmmmm thanks to those who took the time to reply.

 

Yep thats about it and as to heat due to the gears--Thats the reason for the aluminum or alamag end bells. They disipate heat very fast and heat was never any thing we had to deal with. As to reversing gears there are many that you can flip top to bottom but the time to do it is the same as installing a different set.You have enough information here to make a decision as to your use.
