Fast Intentions Stage 2 TT build by MA-Motorsports.

Spooler · 01-18-2019, 11:38 PM

One of MA's customers also popped an input shaft. That's why this all came about. He had just installed a brand new Nissan tranny.
To be honest, this brings back bad memories of my 1975 280z Turbo. I popped 3 trannies before I finally had enough and upgraded. I still have the car but it is a love/hate relationship. That is why it is still sitting in the garage.

I would like to think there is a market for some middle ground option between stock and a transmission worth more than the car.

Maybe it's time for someone to explore a new input/main shaft made out of some fancy alloy?

If there was a big demand for it. Someone would be making it now.

Agreed. How many people are actually running north of 600wtq, if that is even the limit or just an isolated incident, ten, fifteen tops?

This^^^^I here of more broken axles and they are few and far between.

I got the axles covered. Trust me when I say this. If our transmission can be broken, I will break it. I have skills in that department. I am not talking about bad syncro's. I am talking about breaking a shaft, ripping teeth of a gear, or the outright explosion of said tranny. LOL I sure as heck hope not but I have already forewarned the wife so she is not surprised if it happens.

R&D is not cheap. GTR guys have Sheap transmissions. The old Borg Warner T5 had G-Force for the Mustang crowd and the 280zx turbo crowd, etc, etc.

FYI, My 04.5 Dodge Dually with a 5.9 diesel has an upgraded transmission. The input shaft is billet and heat treated along with several other upgrades. Someone may be able to do the same to our trannies but what will break next and at what power level will be the big question. The only way we are going to know is if someone foots the bill to figure it out. We may just be at the design limit of the tranny. I know the diesel guys with NV5600 or G56's gave up. They just changed out to an automatic since the R&D was already massive for the 48re/47re auto trannies.

I have looked high and low for a billet CD009 input shaft with no luck. Only thing we can do is see if Sonnax will make one.

You gonna have to get traction before you begin breaking the large parts

With the potential power you’ll be making;you’re gonna draw a lotta black lines

If I had to guess the problem happens when you shock load the input shaft. Say you are in it all the way and you hit a bump, you loose traction, and then the car hooks back up hard. That's what will kill an input shaft on the street. Drag strip issues all depend on how good the prep is. If it is a good prep, it can be very hard on drive train parts.

Just ordered some new tires. Going with Bridgestone S007 for now. My back tires are done and it is too cold to be messing around with R888r's.

Spooler · 01-23-2019, 09:55 AM

Dang it. The 325/30/19's S007's are on backorder until mid February. Frustration is setting in. Guess I will try R888r's.

solidus · 01-23-2019, 04:21 PM

Spooler the 888r hooks good for me on 17psi WOT logs. But I'm in Florida so the coldest I had them out doing that was probably low 50s. Just had to drive for a while before I had confidence to do it with some heat. I had planned to do them in 325/30 on Nismo's like my spare set with RE11S but the 305 888r actually sits wider on the wheel.

I have 11.5 in wheels. No problems for me.
