Quaife Sequential for NA & NB
Quaife came out with this last year. https://shop.quaife.co.uk/gearboxes?...e=13&vehicle=4 They offer 4 different options for the NA/NB. The 375bhp limit it's somewhat restrictive though. The weight looks to be the same as a stock 6 speed.
The price is pretty tough to swallow. After seeing my friends BMW converted to sequential I had to peak at our options. One can only dream. :-)

Yes, it's possible to instantly shatter a gear by applying eleventeen-hundred ft/lbs of torque to it with sticky tires and an adequate rear suspension.
But the track crowd, who seem to be the ones killing 6-speeds most frequently, have demonstrated that it's not hard to do so with levels of torque and HP comparable to what many of us run reliably on the street through 5-speeds. The difference would appear to be that they are producing said HP on a nearly continual basis for tens of minutes or even hours, rather than in short bursts of a few seconds at a time.
It's this continual HP production which leads to the generation of heat in the gearbox. Heat softens things, reduces the effectiveness of the lubricant, changes mechanical tolerances, etc.

How about a slightly different question: Would a 6 speed last ANY LONGER with a transmission cooler?
I would say yes. There are high powered cars that are stock with a warranty that have transmission cooler.
I made a transmission cooler thread a while back, it's somewhere on here.

I think a cooler would extend the life for sure. I also think a traditional trans mount would help as well. I can't help but think the case is twisting slightly when things get hot. Would love to hear some thoughts from BBundy or other engineers.

The69G is rated to 750HP.Should be plenty but eye watering in price.

That was my thought. Built whammy engine. C30-94 Rotrex on corn. No roof, maybe 1750lbs, many aeros. 15x10 6UL's and 245/40/15 R7's and the pile of 245/580R15 R80's I won a few years back. Much like the 200whp ITB motor we just built, it has no logical reason to exist and won't make me any money. But if I can make it happen, I will. Figure 15s under SM lap records or thereabouts.
Epic is a good word for it.

In light of Emilio taking the plunge I am bumping this thread back to life.
I am also going to drink the cool aid in late March. Honestly it's not that expensive after selling off both of my 6 speed transmissions. Money is finally starting to loosen up so this should be a good year for racing.
I am lost on how to handle the flat shift and auto blipping with the MS3. I am hoping the ECU supports that. Thoughts on the matter would be appreciated.
