At 400+hp, What kills A904s?

I will make it super simple for you....if someone wants to run a 4 speed for the fun factor, great, I have a couple 4 speed cars and they are fun but I don't race them or even have them in very rowdy street strip cars but some do......in regards to the 904 they are a phenomenal transmission and are way faster than a 727 and safer and I dare say that 90 plus percent of the stock eliminator guys that have to technically run a 727 case have 904 guts on the inside as they are obviously lighter which simply equates to a faster overall package. The argument of it can't live over a certain power level is a moot point as every part of these cars can say the same thing and as power increases things need to be modified appropriately.

That all makes sense, especially in the context of a class where every advantage counts.

I don’t doubt that dollar for dollar, a 727 is stronger, at least at the lower investment level but if I was in a position to compete in any non bracket racing class, I would be inclined to go for the less energy hungry, less massive option given that the 904 could be built to withstand the stresses without reinventing the wheel.

If someone faced with the same challenge came up with a different solution, well that’s what makes racing interesting. I certainly wouldn’t call them stupid for disagreeing.
