RJM GTR Intake Lower Manifold...oh yes!

Boss_302 · 04-28-2016, 07:56 AM

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

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.

bullitt5897 · 05-03-2016, 07:05 PM

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

bullitt5897 · 05-03-2016, 07:07 PM

Pretty darn flush:

bullitt5897 · 05-03-2016, 07:08 PM

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

Rusty · 05-03-2016, 11:24 PM

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.

bullitt5897 · 05-04-2016, 01:54 AM

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

Rusty · 05-04-2016, 03:32 AM

Then what good are you?

bullitt5897 · 05-04-2016, 10:02 AM

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.
