Everyone, We are still catching up on a backlog of manufacturing work. We should be testing the kit in the following weeks. We had some additional changes to the intercooler design and should have the new unit in our hands within the next week.
Our schedule is as follows: Next Week: 15 Closed Deck blocks being cut and built (if you want one they will be in stock next week) Following week: New version of supercharger parts are being cut. Test fitting and testing begins. 3rd week: More testing on the Supercharger kit. We will not release the kit without extensive testing and documentation. This is a lessons learned from previous products and we will ensure you have all the details prior to purchase or deposit. Pricing for stage 1 kits are currently going to be set at $9,999.00 Pricing for stage 1.5 kits are currently going to be set at $10,500.00* Pricing for stage 2 kits are currently going to be set at $11,500.00* *Pricing subject to change based on testing. Also will require supporting mods. |

Still really edging for the CARB. any idea of how long this part would take should stage 1 be carb legal? Sent from my SM-G950U using Tapatalk |

Is there a full listing of what comes with the stage one kit?

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

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?

How did you miss those posts? |
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. |

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.
http://www.the370z.com/3306182-post282.html http://www.the370z.com/forced-induct...370z-info.html No way in hell is ANYONE running around at the 600hp level on the stock transmission. |

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. |
Bigger axles won't make the 7AT last any longer or solve the 7AT/torque issue unfortunately. A lot of Q60RS guys who've tuned their cars are seeing big torque gains down low. I'm not sure how long their transmissions will last. Not sure why Infiniti just didn't use revision B aka Jatco JR711e transmissions but I think Infiniti purposely minimized the torque in the lower rev range to preserve the transmission. Time will tell.

I know it's a little chunk more; but my plan was to pull my transmission & have built by Pat@level 10 when that day gets here for boost.
I'm considerably under the torque wire with 314/264 Rwhp/Tq...though I'm sure they gauge it at the flywheel. But that's a 5-6k expense,that I have acknowledged with the 7A/T. Hopefully with my current fluid change intervals; it will live till then. 82600mi. & still pulling strong. I was really looking forward to seeing the prototypes @Zdays, but also understand how sh*t Happens & they really want this kit to ridden of flaws from the start. A little easier for us guy's in the US to get shipment to & from vendors...but still an expense. |
So how is this kit coming along? anymore news

They are wrapping up the last of the inventory this week and the supercharger kit news, pics and updates will start flowing again ;)

Torque on a PD SC is going to be nearly flat off idle, so whatever that number is, if it's within specs for thr 7AT it should be okay, especially after tweaking the torque map.
With a centrifugal charger, because the torque curve is much less flat, the irony is, it's actually less wear on the numerically lower gears, which are stouter, but then murder on the numerically higher gears, which are not designed to handle as much torque. Of course, if by 2000 RPM it already past the mechanical limits... good luck. |
I've been watching the dyno numbers for the new 3.0TT Q50/60's which use the same transmission as the Z/G37 and many are making relatively big torque numbers very low in the rev range where the stock car did not. I'm wondering if they use the "B revision" model of our transmissions which are rated at 400lb-ft. and found in other Infiniti/Nissan vehicles. I have a Q70S in my garage as well but I haven't taken the time to crawl under and look at the transmission code.
Respectfully, I'm not sure about the CF supercharger being harder on the higher gears. You're still experiencing the peak torque/hp in each gear you redline. I'd think it'd be just the opposite as you're far less likely to redline 4th-7th (on the street anyway) and more time redlining in the first three traction-challenged gears, LOL. With the PD supercharger, you'll have all that torque down low and it'll get used more often than a torque peak at 5K rpm. Tuning to limit torque (for a stock transmission) does make sense. I just wish we had more hard data on long term reliability at 400lb-ft. |
This kit is really tempting, gotta way the benefits vs the extra cost vs a centrifugal kit. I wonder if the Fast Intentions flexplate alone with a transmisison cooler would be enough to reliably handle 400 trq.
Any hood updates? I think a lot of guys would like it to look as OEM and subtle as possible (no big noticeable vents down the sides, just keep the one in the back of the dome) |
the debate:
Whipple PD SC kit vs Vortech A2A kit + 2015 Nismo front and rear bumpers..... |
not sure if supercharger thread or automatic transmission thread
|
|
Nice! Do an M3-style simplenpower bulge.
