I was told an 8 week turn around... it's been 8 weeks and I asked for a refund today. As soon as I get the money refunded I will buy an available hood.

So any idea when Stage 1 will be released and ready to ship?

The schedule has been posted above. There is more testing to be done. Once that testing is complete they have stated they will open a new thread.

500whp with CARB is a big deal. I am not familair with Whipple SCs, how does it differ form Rotrex and Vortech units?

Read the thread. All is explained.

About halfway through this thread now. i was pretty set on Topgunz upcomming a2a Vortech kit, but now this definitely has my attention. 500/400 with CARB is pretty tough to beat. The 7at was a concern, but it seems you guys have considered that with the stage 1 kit. Any chance you guys will do an initial forum group buy deal?

Where does it say in the stage 1 kit that they have the 7AT covered, what parts?

Zat_Zuma

It has been solved with posts in Fast Intentions thread and other threads throughout. You have three choices. Level 10, Z1 Motorsports and FI.

How did you miss those posts?

I already know all this, I have read possibly every thread here on boosted 7AT and then some.

What I was saying, is because 'Brucelidat' made it sound like the Stage 1 kit here comes with mods to help our 7AT handle the power as I thought was also being discussed at the beginning of this discussion. But I did not see anything to do with 7AT mods in the Stage 1 parts listed just recently, hence my question to 'Brucelidat'.

According to the guys on the Infiniti forums the Q50 TT and even the new Q60 TT still use exactly the same 7AT. Some users there think the only difference is that they have bigger axles to take some of the stress from the extra TQ.

Ape Factory

I think he's referring to the RJM kit being "compatible" with the 7AT and no mods or mods that come with the kit. Since the initial post raising the question says "you guys (RJM) have considered that with the stage 1 kit." That implies the 7AT issues aren't an issue with the Stage 1 kit as it sits.

But we all know the 7AT can't even really handle the Stillen kit, let alone a supercharger kit that produces significantly more torque lower in the rpm range.

They said that 400wtrq is a safeish range for the 7at which is what the stage 1 is supposed to be at. It would probably be safer to do the valve body and flex plate upgrade to be safe though since that is supposed to ne good for 450wtrq. A safer option would be a centrifugal sc kit since the trq ramps up more gradually there, but you won't get that low end grunt obviously.

The Jatco 7AT revision A is rated at 295ft lbs. and plenty of folks have had issues with that tranny and a centrifugal SC. I'd think the whipple's low end torque would kill it in short order.

The full build uses the valve body, flex plate, torque converter and new friction plates to the tune of four grand.

From what I've seen, it's more of the tune that causes premature 7at damage for the stillen setups. That or just plain bad luck, since I rarely see them take a dump. There's people including me who have ran the stock trans fine for many miles. Look at the q50s running stock trans over 600whp perfectly fine.

Ape Factory

I've actually never heard of a Q50 running 600hp with a stock 7AT but I've honestly not been looking. Is there a thread where someone's been pushing at or above the RJM's potential hp/torque for some time? Most of what I've read is them starting to slip at under 5k miles. I would LOVE it if I could run the stock transmission. I'd consider keeping the car longer and going with the RJM. I'm also 500 pounds heavier than a Z so that may have an effect on longevity.

No way in hell is ANYONE running around at the 600hp level on the stock transmission.

Evan (StillenZ84) has the most experience with FI and the 7AT. He could probably tell you power limits on the stock tranny.
