Coming from the best Nissan Infiniti performance shop(Z1 performance) in the Southeast they claim you do not need to work on your transmission at all with just a supercharger upgrade from Steelen

 

I'm highly skeptical of anything Z1 says after reading some user experiences.

 

Same guys who ran Exedy disks, Fast Intentions Flex plate, and 24 row AT cooler on their boosted 370z?

At a minimum, you need a transmission cooler but I'd go the route they did and consider clutch packs. The G transmission is only rated for about 290 ft. lb. tq. in stock form. That instant TQ a SC provides will grenade your transmission. Check out the Z forums for some real info.

 

The Stillen S/C can vary in power quite a bit and will be the variable how long the transmission lasts. There are people with low 400 WHP and owners over 600WHP.

 

From what I heard from Sebastian @ SpecialtyZ and several others on the forum, 450whp should be fine on stock transmission.

Still obviously going to be more wear and tear though. So YMMV.

 

Eh, stock rating is the stock rating...

RE7R01A is only rated for 295 lb tq. It's that instant onset of Tq and heat that gets it. I'm sure you can baby it and get by but who boosts and does that? Cooler at the very least if you're boosting on a 7AT @400-450

 

The TCU treats the trans with kid's gloves. It sometimes overrides manual setting when I'm at the track, forcing me to short-shift or ignoring down-shift commnds. Quite irritating. Level10 says the top three gears are quite weak.

 

I would argue that the centrifugal units in question have the slowest onset of torque of any supercharger style available, but that certainly doesn't negate any of the good advice for beefing up the transmission that follows.

 

You gotta pay to play. It’s that simple. I’ve decided to stay N/A it’s fun when gain a few years I’ll probably build another motor and turbo it but I’m just taking my time. Buying quality parts and not cheating out has helped me. I’m making great power with three bolt ones and a tune lol can’t complain.

 

Will you please explain exactly what you have done? Thank you

 

It’s in my Signature dude.

DAMN. Those are some good *** numbers. props to the tuner and choice of mods.

 

I'm going to echo you on on this part bart. I've read this time and time again on the Z forum. Go bananas 1-4 but stay out of boost 5-7.

 

I'm looking at the q50 3.0 TT when baby comes, do we know if it has the RE7R01A?

 

It does but they have dual transmission coolers and beefed internals to handle the torque.

Mod on.
