Here's the Q50, he's been running around these numbers for a good while now on stock trans. He also daily drives the car without a filter cause he's crazy. I honestly thought something would have blown by now. https://uploads.tapatalk-cdn.com/201...01fb08e67c.jpg

Do you have any more information on that particular car other than a shot of a dyno plot? JMS is my backyard and I've been on their dyno. How do you know this car is a 7AT? They come with 6-speed manuals as well. There's one sedan in town that runs the SC kit but I'm pretty sure it was a manual tranny.

No filter IS crazy. I've taken apart too many damaged turbos to ever run without a filter, LOL.

What are his trap speeds/times?

@ Ape...Never heard of a Q50 with MT.

This is a 7at. I think the first year of the q50 came in 6mt if I recall.

He has trap times on his IG. I think they were mid 11s.

Actually I know Eric. Met him at Nismo Fiesta a few years back. Very nice guy and his car is indeed a 7AT. I don't know how in the hell that transmission is holding up being completely stock especially with the extra torque E85 produces. One lucky SOB.

I might have to reconsider selling the G for a turbocharged German car.

Be nice to incorporate some type of vents to dissipate the heat being produce by the blower

I wouldn't be surprised. There is a guy here in Australia with a GTM TT 7AT running 468 whp and 550nm and the only upgrade he has done was the flex plate. He said it has held fine since 2012.

550nm is about 405 ft.lbs.

Man, that second PS hood looks great. Would be perfect with the vents from the AMS hood.

The Q50 has a different model RE7R01A tranny then us. Different TQ converter specs, different gearing, different shift programming, most likely different clutches and band. I would be hard pressed to say you can compare their's to ours.

Check the FSM for reference: 2009 vs 2015

That is actually the same trans in the G37/370z... The RE7R01A/JR710E is rated for 295lbs. You are thinking of the RE7R01B.

No, I am talking about the same model tranny but it is changed. They tweak each model tranny from year to year. The Q50s is rated different across the board. Look at the FSMs. If you reference each FSM you can see the slight changes made to the different tranny sub-models throughout the years. Not all RE7R01As are made the same it would seem.

Hmm interesting. I just assumed it was the same with beefier clutch packs. Time to do some research.

So is that just for the Q50 or is that also for the 370Z 7AT? I.e. could the later models have a stronger tranny?

Yes, there are different variants of the Nissan 7 speed transmissions all with different build specs and control software. Torque management, engine variables (programming) and even torque convertors will help prevent damage and help maintain transmission life.

The magic number for our cars is still below 400 ft-lbs of torque and its the 4-7 gears clutch packs that are in danger of being slipped around that torque range. It's amazing how just little material is in those clutch packs.

There is no magic solution to this problem. If you want to boost a automatic car and have more power and torque than stock, you need better clutch packs, torque convertor and heat management. OR eventually you will burn out the transmission .... period. Just like a manual clutch will eventually fail from more power than stock.

Consider a upgrade to the automatic transmission clutch packs, cooling etc for a car you want to boost and make more power. Or don't boost because you will wind up paying way more in the end.

The parts you need are out there and any competent shop that's local can do the work for you. If you want the best and can afford it, Level 10 is the shop to use.

There are NO shortcuts

So you think the clutch packs (in addition to a trans cooler) are the most important upgrade over the trq converter or flex plate for a car running high 300s/400ish trq?

I would do all of the above .... only as strong as the weakest link

I agree, outliers notwithstanding, flex plate, torque converter, valve body, clutch plates, transmission cooler. It's my understanding (and maybe it's just favorable marketing) that the upgraded clutch plates take someone with experience to install them due to the extra thickness of the plates? Which is why lots of guys have their transmissions shipped directly to Level 10. The valve body is matched to the TCU so you need to use the one on your car, again necessitating shipping it out.

It's kind of why I was interested in the "B" revision transmission. At least it's rated at 400lb ft. out of the box. Figuring out which cars/SUV's it came on has not been easy though.

:wtf2:
any mod feel like pruning this thread and moving the 20 pages to the 7AT & power sticky? There's alot of decent info in the discussion about the 7AT in here which will probably be hard to find to anyone searching

No one in here with a 6 speed is spending 20 pages to figure out if they will need to change the stock clutch to go FI

Get your tuner to ramp the timing down before the shift point like the OEM's do and hope for the best or cough up for the upgrades required from Level 10 or whomever

Yea no kidding, let's get back to why we were brought into this thread. This kit being produced! Any new updates fellas?

They said it's coming pretty soon, exciting stuff. It's really great that an older platform like the 370 is still getting some great new after market products and support.

What I said exactly ½ year ago. --> http://www.the370z.com/forced-induct...ml#post3600673

If we pruned the posts about ATs and the posts about possible hood designs, this thread would only be like 2 pages.

hood designs are relevant because they are necessary and specific to this kit

So is the 7AT and those who own a car equipped with one who are considering this kit.

I understand, I am one of those, but it did get too AT and AT upgrade focused for a bit there. Still good info though.

Could I wait till the cluch packs burn out then upgrade with the Exedy clutch pack then?

Preproduction Heat Exchanger has arrived! Progress!!! More preproduction parts will be wrapped up in the next weeks.

Here are some pics:

Notice the large cross section and direct bolt on billet 55gpm waterpump.

Here are the pics since Photobucket extortion for $400/yr

thats a big *** exchanger.

Yes... yes it is. I got to design it to give us the most cross sectional area for heat dissipation and with triple pass. Fluid stays in longer and with the pump it will perform like no other! They asked me to design it to run on multiple platforms and they are going to use it as an upgrade for the new VR30 platform meaning there will be a plug and play application for the Q and new Nissan Z.

YAY... Progress

:iagree:

new heat exchanger
 

I like the way they integrated the pump. Nicely done!

I designed it to be one seamless unit. I wanted a user to be able to easily service and install with minimal hardware. They should have mock up pictures this week

So after sitting here over the last two days reading 48 pages there seems to be more concern about the hood than anything else. People have to understand that when innovation comes around, things change. Compromises have to be made in order to ensure success of the product. Not meaning compromise of the product itself but of the initially designed product (the car) that wasn't built to take every single thing into account.

Also some people have to understand that not everyone here follows the popular kids on this forum. I've been part of this forum since 2010 and I still know only a handful of the big players here. If you're not directly linked to the vendor who is designing said product and someone questions who you are and asks to provide proof of expertise in the field, it would be wise to do so (something in the "about me" section of your profile) as it turns out said expert is helping in design and sales pitching. Reacting the way he did just potentially killed a $10,000+ sale, maybe more as other people could see it and think negatively on his association as well.

From what little I can see (thanks photo bucket) it sounds to be a promising endeavor by this company. Scrolling through what I can see in face book (no account), I'm not seeing much there either. I think an update on the project (lots of pictures) will solidify the reality of this project, put them on the first post of this thread as well to increase interest for people who are just now reading about it and can get a better picture in their head as they're reading through this book.

Lastly, some years ago I inquired about a positive displacement SC possibility for the 370Z on this forum and I was met with nearly 100% opposition that it would be impossible due to the VVEL system. Which made no sense to me at all because there are plenty of other PDSC vehicles with variable timing that are out on the road. Where is this opposition now? I don't recall one single post on this thread saying anything remotely close to what I received.

Well....the kit is a great thing.....but no way you cant just dismiss the hood deal...

There have been a good amount of pictures and the ones i've seen, seem to work just fine. I think they have been plenty good with keeping the community informed and updated i know they were close with the z days in May and had to push it back to make sure this kit is 100%. Me personally I would rather them take their time and deliver a solid product just as FI has. They had to squeeze every drop of space out of this kit and if the hood is the only downside for a change because of this, im sure people will be understanding. Just have a little faith in them. they make kick *** products and im sure will deliver on this as well, great things come to those who wait:tup:

The hood mockups I've seen don't seem to take into account that the clearance problem of the Whipple s/c (as I understand it) is mostly in the front section of the hood -- not the topside so much or the back of the hood. Repositioning (or eliminating entirely) the cross-support bar will be an issue as well.

I think a lot of folks are following this thread just out of academic interest to see where it goes, and what it does on a dyno, but as far as making all the concessions necessary to actually make it fit their own car, very few will bite if the hood can't accommodate it tastefully.

Just my two cents...
