:drama:

being in here is like sitting outside someone's window and touching myself inappropriately.......love it :yum:

my god man Get Back To Work!!!!! :rofl2::rofl2:

this is work. you ever try to balance on a tree limb with only one hand for support when I'm fondling my own balls and jackin it?

serious core strength needed. :wtf2:

intake ports on the rough side... have you ever seen/held/touched a CNC head?

like i said when cosmo said it, yall's concerns about selling he product untested is legitimate, but some of us (individuals) are stepping up to try to fill that need. please be patient with us, and understand that we are trying to help. i also feel like you guys are placing too much emphasis on the performance of the entire combination on the lower, particularly due to the price. it cant do the job on its own. ill reiterate, the runner length and plenum volume are going to be determined by the UPPER, not the lower. all rjm has done here is created a product that facilitated the use of any gtr compatible upper manifold onto the HR/VHR platform, with a much nicer transition between runner angles than anything else previously released...

:icon18::icon18: This just kill me. Dude you need some therapy sessions :rofl2:

RJM and AAM should get together and sell a snake oil package for 4K.

:iagree:

Ryan with RJM Performance (NOT RJ Manufacturing) is working on one and expects to have something available soon :twocents: He plans to have one ready for a local guy to install and drive down to ZDayZ next month.

Jake or James, when you install, take pics down inside the runners to the heads. Someone said its gasket matched which from my experience ends up being a bad thing. You end up making a 1/8th lip all around the head entrance. So while it may be wider, smoother and have a straight shot vs zig zag like OEM or GTM, if you made a huge lip for the air to hit going down, thats going to negate any benefits from the better design.

And nothing to this date proving anything on this product. It's funny how some of the arrogant people on this forum push products with Absolutely nothing to show. Instead of becoming a vender and supporting the forum here they have spineless people advertise.

That may be but hell people spend a fortune on looks. Maybe people want the bling of a GTR mani or aftermarket one with zero gain. The CF JRC upper plus the RJM lower will run just under $10,000. Maybe they want that.

Jake has been testing this n/a and I hopefully finally on the dyno tonight with some real world numbers for the NA guys!

I will say from our conversations it's looking to be very promising!

As far as gasket match runner picture I think I already have one. If I remember correctly it was really flush. I will post up what I have in a sec

Pretty darn flush:

That's before I finished aligning it and bolting it down

What you needed to do, was to have the lower manifold flipped up side down, and lay the gasket over top of the ports. And put the gasket on the head. So that we can see the match between the gasket and the ports look like. What you are showing, doesn't do me any good. If you are trying to show the first port. Can't see down in it. Need better lighting.

This was all I had... During the install.

Then what good are you?


:rofl2:

just as an fyi for those looking to get the kit and want to run fuel pulse dampners you will want to purchase these fuel dampners:
https://www.radiumauto.com/Fuel-Puls...Kits-P759.aspx
20-0177 FPD-XR, 8AN ORB

These are rated for 50+psi base fuel pressure. If you do not want to run one I believe RJ MFG is willing to delete or provide a delete for it.

Jake is currently testing the setup for N/A and is working through some tuning hurdles with his short ram intakes and MAF sensors. Since he is in uncharted territory he is working to find the best way to maximize the benefits of this conversion. I know as I am testing and he is testing we both agree that we can feel an immediate shift of power in the bottom end and mid range to the left in the powerband.

Well what does that mean?

A shift to the left means that torque comes in sooner and harder. It means that you will have more power under the curve where it counts in the mid range and the low end.

In a NA application we dont know what the GTR upper plenum will do at higher RPMs until its on the dyno. However, Jake is looking at the upper plenum and feels with some larger end tanks there should be much more to gain. Again this is just our conversations on the subject and we wont know 100% until he is able to get on the dyno.

For the forced induction side of the house me and a few others have already noticed a dramatic improvement in torque and mid range. I should be on the dyno next week and will have some preliminary numbers on my old fuel pump. Following Zdayz we will have a triple pump solution designed and built. Thats when you can expect big numbers from me.

Lmao big bore TB's $2600! Wtf are GTR manufacturers thinking??!?! Jakes are only $800!

http://i39.photobucket.com/albums/e1...psinyuaz7w.png

Those intakes are nice but even at myrtle pricing I couldn't justify spending that kind of money on an upper intake plenum... The all carbon ones is only $5-6k though lol and judging by the end tanks I would not expect massive gains... More of an eye candy piece.

The AMS is insanely efficient and makes way more power than my Greddy intake manifold but even then I couldn't justify the thousands of extra dollars.

you can get an entire FI TT kit for the cost of just that upper mani alone lol

Alpha makes parts for people who can easily throw around hundreds of thousands of dollars, 10K for their consumer base is like 500 for us. They just set the price by what people are willing to pay.

:iagree:
They feel if you can afford a GT-R and have money to mod it. Why not charge those prices.

Bullitt any word when you're going to get some numbers up. Bobby just posted the conversion on a 08 350z oem upper and lower it made 401 on 5psi, with the conversion it made 430 and picked up 40 ftlbs/trq. Im just curious to see how your set up will respond

We will be on the dyno this week.

AS elmo eluded to earlier. There are some preliminary numbers from a stock block 350z HR. This is a stock block with over 80k miles on it and over 40k of those being boosted and beat on. Needless to say the motor isnt the freshest in the bunch and there is room for more potential.

They started with And ended with @ 5 psi:
http://i234.photobucket.com/albums/e...ps1rrq0ni8.jpg

400rwhp and 326ft/lbs @ 5psi of boost

Then after the install with the same dyno and same tuner were able to crank out

430rwhp and 341ft/lbs @ 5psi of boost

Analyzing the graphs we can see that the intake manifold allowed for more aggressive tuning without compromising reliability. The highest gains we can see are a whopping 42whp and 48ft/lbs at 4600rpm! the numbers just didnt stop there. We can see that the intake made more power throughout the entire power band! With the peak power climbing an addition 30whp and 15ft/lbs at the top. Proving that this part does in fact make power and will also make power on any 370z with forced induction.


The intake also allowed them to run more boost safely within the tuners limits or 9psi pushing out the following numbers:
http://i234.photobucket.com/albums/e...psu58ufjd5.jpg

@ 9psi they were comfortably sitting at 523rwhp and 400ft/lbs.

This is further evidence that this is a mod that will help your gains no matter what the internet naysayers think, there was R&D done on this product and the numbers will speak for themselves.

Stay tuned for more updates from those of us waiting on dyno time. :tup:

also, a lil birdie told me there might be one available for grabs at Zdayz in the drawing!!! WHAT??? yep... And a Zdayz special deal too... Just saying there was a little tweet tweet and I know atleast one lucky soul is going home with a new conversion....

You mean the auctions and giveaways i have never won in 5 years of going? Yea I'll be in high hopes for that lol

I have never won either but Dai won 3 prizes one year!

Your luck is as good as mine. What luck? :shakes head:

The winners seem to be rigged :stirthepot:

I may actually participate in the drawings this year if this is available.

LOL, Yeah I need some parts myself. With my luck I would get 2 more herniated disks in my neck from the guy behind me bulldozing to the front to get his prize. Well, I got a totaled car and 2 herniated disks for my birthday, why break the trend.

Ill take it this fpenvy

At least you're getting fast intentions mufflers after Zday. :iagree:

So it made a ton of power with the new RJM lower and GTR upper both at 5psi, but was the base run tuned also? Meaning, car shows up, it's tuned to 5psi as a fresh update targeting same AFR, timing, boost etc, manifolds then swapped, and tuned again for same AFR, timing, boost etc. if that's not how then it's not comparable only because the original 5psi tune could of been old and needing an update. Also swapping manifolds over and changing targets a lot doesn't give us good numbers. They're great numbers though over all! Customer I'm sure is happy to make all that!

The original 5psi tune was optimized for the stock intake manifold. The GTR conversion was done and was retuned and optimized. That is the most comparable you can get. It's a straight apples to apples comparison. This is what people can expect to make as far as gains on low psi tunes. The dyno's carry similar signature attributes to GTRs and similar attributes that I saw on my GTR conversion before rjm. These are legit numbers and real world results.

Throwing on a whole new intake system is going to to dramatically change your afr. We saw that with mine... And I wasn't going to spend another $600+ for a retune on my old tt kit. So my numbers will be probably the max you can expect out of the kit.

Umm boost went from 5 to 9psi so the 100 gain comes from boost. As for the 29hp and 15tq gain from swapping manis, what tune was on the car before? Only true test is a safely tuned car same day, then swapped, then tuned again with same timing and boost and target AFR. Any one of those things change you cant say its on the mani!

You coulda just turned the boost up for free.

^agreed those numbers posted are deceptive. Anyone here doing real dyno testing like COSMO suggested?
