RJM GTR Intake Lower Manifold...oh yes!

bullitt5897 · 05-12-2016, 12:08 AM

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?

bullitt5897 · 05-15-2016, 09:16 PM

Harry forgets to read the analysis as usual. Ohhh and btw more dyno numbers are coming from NA and turbo applications. Needless to say the manifold makes more power 5 psi to 5 psi... As per my analysis you can see gains throughout the power band... But hey I already know Cosmo doesn't want to see this product succeed due to his prejudice and hate. As for a pull one and install another the same day from a third party well good luck with that... That's a big ask from most people especially given the time frame to do the work and be on the dyno. The best you will get is like comparisons right now and the dyno sheets posted above have been explained. It is not deceptive when you provide a same psi graph and then show an additional graph at a higher psi showing what you were able to do.

Update: Just wanted to pop in and say I haven't fell off the wagon - my company sent me out to Texas for a month to work. Didn't see that coming so quick, but hey, overtime and benefits are calling my name.

My plan is to install this setup next month with a custom return fuel setup, and also later adapt to the CJM road race fuel pump setup as well. I'm still trying to work out how to dyno this fairly - I severely doubt I can install all of this in one day, let alone between dyno sessions. Maybe I can do a two day deal, and just do some correction factors.

Awesome man! cant wait to see yours and others results in addition to mine.

Another dead thread / unfinished RJM build with no results?

OP, give us an update.

370Z JT · 09-04-2016, 06:18 PM

Jake had not finished his testing and was in the middle of other business testing when RJ MFG sent him the conversion. Being as I know what is going on I dont see an issue with him taking his time with it. But many of you dont get to see the behind the scenes and I totally get all the questions.

At this point RJ MFG has focused on this for the Forced induction market. However, I will talk to the parties involved and see if there is a way to get the NA portion back rolling again. For those who dont know... They just had another car make 70+whp with just changing the intake from stock and a slight retune for the higher airflow!!!! Thats massive gains on the same PSI level...

Spooler · 11-12-2016, 09:39 PM

Anymore news on these? The AMS GTR intake looks awesome but dang it is expensive.

Zbrah · 11-13-2016, 12:29 AM

Op- been waiting for some NA results...surely, it's installed by now. Where are the results, man?!

If that is what happened. He needs to come on here and say so. Then close the thread. Otherwise, people will be calling BS for a long time on him. Which is what I don't want to happen.
