I see where they advertise their transmission is IMCA legal but I don't recall it being listed with the Bert, Brinn, or Falcon. Where does this transmission stand as far as the IMCA rules? It sure sounds like a sweet gear box!

You guys might want to compare apples to apples here:

Here is the Layne your talking about... http://www.hrsapplications.com/cgi-bin/shoppingcart/cart.cgi?action=link&product=53&uid=12

Brinn has a comparable tranny that IS NOT what you guys are pricing as far as internal weight.

This Brinn (Pro Series) transmission is priced at 3,400 dollars without ANY other parts.... If the standard Brinn were comparable to this transmission, why would they manufacture a completely different transmission (Pro Series) that is lighter in rotating mass? HMM?
Take a look....
http://www.brinninc.com/pages/Tranmissions.html

Here is what the site states fyi:

The original Brinn transmission revolutionized circle track racing when it was introduced more than ten years ago. Now an entirely new Brinn Pro-Series transmission has been developed. This new transmission is as big a step forward in transmission technology as the original version was when it was introduced. In the new Pro-Series transmission the clutch has been moved to the input shaft.
The Pro-Series has been designed to fit anywhere that a first generation Brinn transmission fits and can be used with any Brinn or Chevrolet bellhousing.
The new generation Brinn Pro-Series transmission features the lowest rotating weight of any transmission, just 11 pounds. Even better, that weight is concentrated in an overall diameter of less than 2.75 inches which reduces inertia. The diameter of a weight is much more critical to overcoming inertia than the total weight itself. Effectively that means that it, and you, can accelerate and decelerate quicker. In high gear the only rotating components are the input and output shafts, the direct drive and reverse couplers and the clutch drive discs.
This revolutionary new concept in transmissions allows the greatest reliability ever. Since none of the gear train turns during operation there is little to fail. Lubrication is by the splash method and all gears have dog rings for easy shifting. The case is a hefty, well-ribbed magnesium unit that offers the maximum in strength and reliability. Best of all, the distance from the center of the main shaft to the bottom of the case is only 4.25 inches. This is the smallest dimension in the industry.
An important feature of the new Pro-Series transmissions is the integral hydraulic clutch. This unit, which includes the input shaft, clutch assembly and throwout bearing is simple and quick to install and remove. It mounts to the front of the transmission and can be quickly unbolted by removing only three bolts. Just one snap ring needs to be pulled for disassembly, meaning that clutch service and or replacement is easy.
Inside the clutch drum are 5 drive and 5 driven clutch plates. A needle bearing assembly ensures that the clutch drum is well supported and in alignment thus guaranteeing no drag and a positive clutch release.

Brinn has everyone fooled.....make sure you are reading and see the complete story.....

The Layne is a better buy than the Pro Version Brinn by far and is just as light internally. Layne did it with a stock muncie case and have been around for a while....they have been track proven, you can't say this about the Brinn.

I looked at both sites you posted jammin. So the rear mounted starter on the Layne is IMCA legal? I don't think the Pro series Brinn is IMCA legal is it? Either I missed it or it didn't say what the Layne transmission weighed. It does sound like a sweet setup.

I don't have the 2004 rules, but I don't think the rear mounted starter is legal. BUT, I think if you run a Brinn, they require a 14" flywheel where if you run an oem case, you can run a 10" flywheel....something to think about. But, I just wanted to show everyone the apples to apples comparison, because I have listened to alot of people compare it to the brinn, and it isn't an even comparison at all. If it was an even comparison, i guess a full spool versus a mini spool would be the same....and 9" gears that are lightened wouldn't matter either.....

just something to look at.

A Bert or Brinn is still a best way to go.Very Very few racers are using the new Brinns,There just to high right now.Maybe in a few years they will go down in price.

I have a Layne Trans set up with only 3 races on it. The mounting ears on the left side need to be repaired. I will let this go for 2,000. I changed classes so I don't need this anymore. It is a sweet trans though. The rotating weight is so little I had to drop a gear ratio. The engine really rev's fast.
