Hey that's pretty awesome :)

Honestly, I think if you're focused on the market of people using clutched LSDs, they're pretty much all going to put in a diff cooler eventually, at which point the fins are just minor "nice-to-have" things. A little extra capacity and having the extra ports to drain/fill without disconnecting the cooler setup is a win, and I actually like the blocky look.

I guess some kits/controllers will have a temp sensor that wants to screw into a tapped port on the diff, may as well add another plugged hole for that option?

agree with him !

but the last sentence...

Ive seen a few different thread pattern sensor on a various temperature kits/controllers that it would suck if its wasn't the right one!

about 75% (49 out of 63 total) of every sender unit sold by summitracing use the 3/8-18 NPT as a reference...

I love it. The boxy look is nice. Represents business and it obvious someone will know something is going on back there.

Phunk gets things done. Take notes all you other business owners.

Oh ya totally forgot about the temp sensor port. I'll get that on there. Also, I didn't forgot the ABS sensor flanges.. Just didn't draw them yet!

Too many holes for Phunk to handle lollll

Very nice. Do you have a ball park figure on price?

I'm in...Pm the first batch price please.

That is a really good question. This project will have a lot of material removal compared to what I am generally used to.

My software is telling me that I am starting with a 24lb block of aluminum, and making it 3.5-4lb. So thats about 20lbs of aluminum shavings I have to make per piece.

I have to balance the realistic value of the item too. This part does not make power, it does not increase performance, you can hardly even see it when installed. Yet, if one guy walked in my door and asked me to make just one of these custom for him, it would probably be $1200 with reverse engineering and CAD work and all.

I could take a stock cover, machine off the lower half except keep the flange, and weld in a billet section with all the added features, and it could be quite a bit cheaper.

What would you guys say if I asked $450 for the full billet cover? I have seen a place that makes them for DSM/EVO etc and they go for $400, for a much more flat/simple cover applications (much easier to machine).

For $450, make one up for me.

This thread needs to be split so we don't distract from your excellent Road Race Fuel Pump.

I'm not sold on the value of making a new diff cover. I think the Nismo version is sufficient. Are extra bungs really going to make that much of a difference? Diff cooler setups work fine with the stock bungs. It's easy enough to add a T if you want a temp sensor.

Sure, I would pay a 25% premium over the Nismo cover for a nicer version; maybe even 50%, but that doesn't even get us to $200. And it's a pretty small market to compete against an existing part.

Or look at the Grand-Am teams. They have a much much larger budget and they have not seen a need for this. Love your stuff phunk, but I don't think this one is worth your effort.

i think it's a great idea.... pre-drilled for external cooling is helpful... otherwise people have to take a chance drilling the oe unit

The problem is that there are no nismo diff covers. Try buying one tomorrow-they don't exist, and haven't existed in months. Nismo USA doesn't give 2 sh1ts about anyone of us is what it boils down to. If they did, they would be making the f-ing parts we need to make this car go faster. They are focused on the GTR market not us. If they were smart they would warranty replace the oil cooler problem and then build a nismo turbo kit. but when your golden boy and your marketing department suck at fast, just expect to get pimped.

I'll buy a diff cover with some extra cooling capacity tomorrow for 450 from anyone that can send it to me because it is holding up my LSD install.

^ well said. The Z gets no attention even from the US market where money can be made. Then the companies that do take a lifetime to produce. By that time the next model is out.

Back on topic..

Has my Unit shipped out yet?

After looking at this, I would like to see a 1/2 - 3/4 inch spacer and the stock cover??? If there is more room under car a full inch? It would keep the cost down

Unfortunately there is a mount location on the cover, so it cannot be spaced. ABS sensor mounts too.

None have shipped out yet. They should be headed out this week. I began assembly of them Thursday or Friday and ran down the entire parts list and ordered up everything small that I didnt have enough of, and it all came in the other day. Yours, along with the other 3 paid units are in their respective shipping boxes about 70% assembled. I was actually going to start finishing them up this evening!

I can probably get yours out tomorrow if you wish. I will post up if I have any issue finishing your kit this evening.

edit: sorry I did not mean to ignore your post early when I was on here. My previous reply in this thread was posted from my phone. I was sent an email with a comment about the spacer, and I replied to it from my phone without realizing there had been more posts above it that i didnt read.

Welp... one part prevented me from being able to complete shipment on RRPs tonight. I just ordered it. It should be here Thursday hopefully.

Any thoughts on making an oil pan? The GTM one looks pretty good but with all the problems GTM has I have to wonder if it will ever make production.

The GTM pan has been ready. It would ship out same day if you ordered it. But that pan really serves no purpose than the baffle design. A oil pan spacer is all you need to gain quanity. When added up a 34R cooker and Spal fan orb ding where you live is all that's needed. But a average oil pan with baffle would be nice.

The biggest problem which isn't huge is We need more people buying to get cost down while supporting a real enthusiast as Phunk that gets things done. All these tards buying these crappy body kits and interior CF junk with what money they do have instead of real true potential performance parts. In which this is what the car was intended for.

The CF pieces are the best. Nothing says rice like "The whole point of this stuff is to save weight on an expensive car, but I'm actually *adding* weight to my car by layering it over something else."

Let's not forget the cheap Taiwanese coilovers so you can slam it on the ground, yo. And fitting 225s onto 10+" wheels. :rofl2:

An oil pan has been on the list for a long time. I sort of stopped thinking about it on a personal level since what i am doing with the oil pump will almost definitely use a custom lower oil pan anyway. While I have personally not been a big supporter of the aftermarket pans... Its not up to me to decide what everyone else wants, and I have to have wide open arms to that.

Having been designing fuel systems for too many years now, i have learned a lot about fluid control systems and I could probably build a pretty rad oil pan. Oil pan would be much easier/cheaper than the diff cover because it doesnt need to be totally solid billet since there is no load on it. That diff cover, since it has the rear diff mount on it, needs to be BEEF.

Now.. you guys have asked another vendor besides from GTM to build an oil pan also... so I need to choose wisely where to put my efforts. Its easier to play nice and all construct different products for a car that lacks so many. But then for some products, there is plenty of customers to go around and its not a big deal. So it all boils down to interest.

I have a 370z here, and I have the ability to manufacture just about anything for it either in-house, or through close contacts. I am total wide open to building anything that is asked of me.

I would be definitely interested on an oil pan more than I am on the diff cover. That is me though, my car is not a track racer like most the ones in this thread. I guess I fall on the "tard" category Chris mentioned earlier of making my car heavier by making it look nice but hey, it is what it is. With the TT I need all the cooling I can get as far as engine oil goes, I'd be down for a high capacity baffled oil pan.

Just out of curiosity, what is wrong with GTM's offering?

Katy Texas! That place is gorgeous. Used to work there every once in a while like 15 years ago.

The most politically correct answer I can give you is that nothing is wrong with the idea of a product made by a certain company that may or may not be produced within the next 6 months if history repeats itself.

I've actually moved closer to Houston, I bet Katy hasn't changed much in 15 years lol.

GTMs oil pan solution is available now. I talked to Sam about 2hrs ago and he confirmed it would ship the same/next day if you placed an order through their website.

I thought maybe people didn't want it because of the "engineering" behind it, ie: waiting on something better.

I thought you had already picked up the Greddy one. Your Oil Cooler isn't doing the job? My 34 Row and Greddy Oil Pan are holding up just fine with my "inferior" non water cooled turbos.

down for pan and diff cover

No I don't have the Greddy. 34R cooler is enough for spirited street driving but not for track usage in TX summer.

The GTM pan is a serious over kill in which I feel there was no research done other than make a big oil pan cause it will fit. The baffle is wonderful on levels. The GTM pan all you get is a big pan with 3qts more oil. So that said it will take a couple months to bring oil up to temps (unless on a track), once up to temperature all you have is more hot oil. There's no real cooling properties going on beyond a oil cooler. Now the pan cost $400+. IMO get a oil pan spacer and 7'' Spal fan for your 34R oil cooler (considering most already do). In which the the Spal fan you can order different sensors to activate at different temps like 195 degrees. So at 195 you are instantly starting a cooling process. A pan is not doing nothing.

I love my GTM baffled oil pan. Minus cost of oil changes, I thinks it's great to have, just be sure to use a thermostatic sandwich plate. I don't have much issue getting temps up in cool weather. I can't comment on the effing cold arse weather going on right now tho... I'm out of town again.

What do you like about it exactly? How hard do you push the car for one period of time? I promise on the track you will see just as high temps as any size cooler. The capacity doesn't help. It really doesn't help in the high stress areas. There's no cooling properties going on after it heats up.

Well, we have other solutions for oil cooling anyways (setrab cores and/or laminova-style). The whole point with a pan upgrade is to get some real baffling so we don't lose oil pickup volume / pressure in a sustained cornering situation (like a fast sweeper). Basically, we're looking for a poor(er) man's solution for what dry-sump systems do :) Which is why I love my AM Perf pan ( http://www.the370z.com/track-autocro...-oil-pans.html ) - but they stopped racing and went out of business and only sold a handful of them.

i think im going to do another core, need more cooling! LMAO

There is cooling capacity in the quantity of oil. Less recirculation of the same oil means more time cooling off. An exaggerated example would be recirculating a quart of liquid compared to a 5 gallon bucket or a lake to an ocean with temp changes. I haven't gotten to excercize it like I want, but even averaging 95-105mph (avg) in the Mojave desert driving home with temps hovering between 90 and 100 depending on elevation, the car never went higher than 220. I can't say how much is attributable to the larger pan, but I can say that with more oil, it's not so critical to get a change every 3750m. The pan fits with my sway bars and fits with the 2012+ cars. It also sits higher then a tradional pan spacer. I can't find much fault in it. Yeah it's expensive, so was everything else I bought for the car.

Don't put too much fluid in the front clint or else your car be like:

i want my 3 minutes and 24 seconds back please

Try 7 or so years.
