I just ordered the clutch/flywheel from ZSpeed, and Joe asked me about torque numbers at the wheel. I told him no more than 410, and probably 390-400 on 93 octane.

I just ordered the clutch/flywheel from ZSpeed, and Joe asked me about torque numbers at the wheel. I told him no more than 410, and probably 390-400 on 93 octane. I also told him I will never launch the car, or track it. He actually recommended his Stage 2 EZ-Street Quiet Clutch, and while he said I'd be at the upper limits of what the clutch is rated for, that I'd be very pleased with the day-to-day operation of it.
Anyway, long story short, I'm starting to get nervous that I told him the right numbers, and went through this thread and dug out Turtle's, overture's, and redondo's dyno charts. Theirs were lower than what I told Joe...so I think I'm safe. Anyone else with torque numbers on A2A? |

What if you decide to go E85 some day? We are seeing over 450wtq on that stuff. What if you get the 928 full build and throw 13psi at it? Also, what if you decide down the road to swap to a turbo setup where your making over 500wtq? Id go to 450 at a min.

Well...I guess at my age, I'd be more than happy with your A2A setup. I just don't like the torque curves with turbos, which is why I'm going s/c, and want an enjoyable, reliable, fun car. e85 isn't readily available in my area. If I do go with the 928 build after a few miles on the Si, I wouldn't boost pressures higher, and keep them at ~9psi. I'd like to see what others experience with the 928, and if it really provides noticeable and earlier torque.
I'd also probably have a difficult time convincing the wife that putting more money into the car will reap huge rewards! |

Fair enough.
FWIW I had the stage 3 street with quiet disk and i loved everything about it. Next to stock feel, barely audible, not grabby and it held 510wtq all day. If i ever need a clutch again thats the one id buy. The stage 2 Im sure is very similar with a slight lighter feel and probably cheaper.

Early G37 often have a 350z fuel pump housing which doesnt have the hat breaking issue of the 370z or later G37 that use 370z style fuel pump housings.
I have not yet come up with a way to determine which fuel pump housing is in the G37 other than just pulling it from the tank and looking at it. |

I have a question:
With the 7AT, Can the OEM Transmission handle the following upgrades: - 3.0" & 3.47" Supercharger pulleys - 9 PSI Pulley - A2A Kit - 1050x ID - 928 Impeller & High-Speed Bearings / Seals on V3 SCi I understand that the OEM Auto Tranny can handle up to 425 ft lb. TQ max safely, anything past that is a risk. Thats why I ask |

See my other posts, our stock autos don't last long when boosted. I tried mine has lasted 20,000 with a VERY CONSERVATIVE tune just about 400whp. That's with a 19 core Setrab cooler on it and SEB increasing the line pressure also.

So I would be pretty much driving a Tranny Time Bomb until one of three things happen: - Upgrade it with a level10 Tranny - It blows up and Im forced to get a new one - I get the Z1 Excedy Clutch Packs & FI Aluminum Billet Flex Plate This is assuming I have said upgrades I listed a few posts up with a very conservative tune. Welp. Upgrading the 7AT is what I will go for ASAP next year lol. |
