Is he/she well known? That kind of blanket statement is full of problems.

One comment: the dip in torque is my stock clutch slipping a little..but you can see the curve was leveling out already.

If we are operating under the assumption that 400wtq is acceptable with the OEM 7AT, then I think you can just tune it to that target and be done with it.

Sending you a PM

Elmo370z 01-09-2017 03:31 PM

You should be able to control Tq with tuning if I"m correct

bullitt5897 01-09-2017 08:01 PM

For you AT guys you Have three options from level10:

Option 1: valve body upgrade (a must have) this will require sending yours in. Costs about $1k
Option 2: valve body + tq converter upgrade (next best option) costs about $2k

Option 3: get the bulletproof transmission from level10

A couple other options

Exedy clutch pack: costs about $350
Fast intentions billet flex plate: costs about $1k

Now put wtq #s you can safely achieve with these options and the benefits of each.

Going to have to ask level10 on that...

This is interesting i will keep my eye on this development.

I have no problem up-grading my trans.....just want to see the kit on the engine perform & be reliable,without the horror stories of previous SC'd kits.

And what will you be upgrading on the trans? Valve body? Or full blown trans from lvl 10?

jchammond 01-10-2017 09:35 AM

I'll pull it out & send it to Pat@Level 10 & completely go through it.

bullitt5897 01-10-2017 10:58 AM

Just got off the phone with level10. Pat stated anything over 450ftlbs should get a full transmission build for the automatic. Regardless of forced induction method.

bullitt5897 01-10-2017 10:59 AM

Valve body and torque converter will only give reliability within the 450ftlb range

Did he say what the trans will handle in completely stock form?

RJ MFG Said 400 ft/lbs. Maybe we should get back on topic though. I have no interest in reading pages and pages of posts about the woes of people driving Automatic 370s. :driving: <-- (He's not putting into "D")

bullitt5897 01-10-2017 04:24 PM

The stock tranny can hold 400ft lbs reliably. Anything above that runs the risk of failure. Not a if but rather a when scenario. A valve body upgrade pushes it to 450ftlbs safely. Once beyond 450ftlbs other items need be done in the form of a full transmission build.

MCLOVIN 01-10-2017 06:14 PM

I'm so excited for this!

RJ MFG 01-10-2017 08:18 PM

Slight update everyone:

As we work to make the system bullet proof we have come to the conclusion that the unit will not be able to fit under the stock hood. However, we have anticipated this and plan to partner with a vendor to offer two options.

Option 1: Full hood replacement (keeping under wraps for now)

Option 2: A hood cowl add on that will look great on any stock profile hood!

Here is a teaser of what we are working on. More details to come.

Reliability is more important! I don't have a problem replacing my hood if need be.

Note: the design for the hood cowl add on is specifically made so that any body shop can install it with ease. Also we wanted a design that will not leave creases or require lots of body filler to blend. The attachment points will be folded under the cowl allowing for a seamless mating to your stock profile hood.

Our intercooler package is going to be rated to over 1000whp. The design of the intercooler core is modular in that you can add or subtract cores. Currently the stage 2 kit is looking to run 7 cores. The stage 1 kits we are going to offer with a few cores less of the full capability in order to lower the entry level costs. However this leaves everyone an upgrade path just by ordering more cores, new pulleys, Throttle bodies and fuel system.

We are really taking the time to look at this kit from your perspective. We want to provide a very modular, reliable and scalable kit without breaking the bank. Everything we do toward the kit has efficiency, quality, reliability, cost and performance in mind. We want to hit all of these metrics when the unit comes out in may.

MCLOVIN 01-10-2017 08:29 PM

So it's a cut the center out of stock hood and place over design? Will it require a reprint of the hood?

we plan to offer a downloadable template that anyone can print out to make modifications to their hood. The add on piece will utilize the angled edges of the center of the hood for mounting points. Mounting will be done from underneath the hood. We hope to have a carbon fiber option and an FRP option. The level of fitment will be up to the end user. If you want to bond and repaint you can. If your want to sealer and rivet/fastener you can.

MCLOVIN 01-10-2017 08:41 PM

The render looks fantastic! I'm just worried about clean cut lines if it comes in from underneath, that means the cutting to install it will be visible from the outside? Cutting into the hood just makes me cringe lol but I guess a good shop could do it.

Is that cowl functional? Ie..will it bring air past the blower and out the rear? Hopefully so. Maybe add a slot in the front to allow for more air. I do like it though and would rock that for sure.

Curtis_J 01-10-2017 09:01 PM

I'm sure it's very likely been thought of already, but if the hood has to be replaced, a design that allows as much cooling/heat extraction as possible would be very welcome.

Did he happen to mention if they are going to offer a clutch kit like Exedy does? If so, did they mention how much more torque it could handle?

For a lot of us, its the cost of shipping the whole transmission, that really sucks. Finding a local transmission specialist, to do the work, is easier and least expensive than 5K + shipping from Level 10.

No offense intended but I'm having a hard time justifying the 5 K cost too.

Same here, I looked into a manual swap. I got a pice list of everything you will need. I even threw in lightweight flywheel new clutch, the CSC fix kit from Z1 and triple pass MT radiator. All parts shipped to my house would cost $4,515. Now mind that you could do the work yourself that's the price for a transmission to handle the power of a boosted car.

Also I'm in the process of finding a a totaled MT sport package Z to see if it's cheaper.

lj909 01-11-2017 12:08 PM

Based on the initial rendering pics, are you trying to have the throttles in the OEM location?

That is correct. The idea is to give you guys the option to run your current cold air intake kits.

This rendering looks great. I'd do this hood modification even without the kit. I'm totally stoked about this kit and hope it works out. As for now I'm saving my nickels for it!!

we haven't asked about any upcoming product offerings from level10 yet. Our only thoughts are that they would be supplying aftermarket clutch packs with the build to justify the costs. However, that is unconfirmed at the moment. Instead of shipping of your trans you could do the following:

Fast intentions flex plate
Exedy clutch pack
Level10 valvebody
Level10 TQ converter
Transmission cooler

Have a local competent shop install it all. That is if shipping is an issue. Now if new gears need to be made we can handle that if it comes to it.

TopgunZ 01-11-2017 02:56 PM

Anyone have a link to these clutch packs?

jchammond 01-11-2017 03:32 PM

Not holding you to anything RJ MFG,
Have you guy's calculated an estimated HP/TQ potential on 93 octane fuel?
And on a stock block vs. a built bottom end?
This is all pending our AT's & Stick Trannys are built to hold...including a free flowing exhaust & cai.
I plan to be at Zdayz this year & this kit is sounding more inviting daily!

Curtis_J 01-11-2017 09:31 PM

91 octane is the highest I can get locally, and no e85. Thinking I'll likely need a methanol injection kit. Or race gas. But I can only imagine how expensive that would be, considering that 91 octane here is roughly about $4.50/gallon in US currency.
