So much this!

Only heard about these a few weeks ago. Wonder how the CPC or Plazmaman go in comparison. Alright guys, here is all the testing & results on our manifolds. Head to our online store to grab one: https://www.otakugarage.com.au/shop/intake/ Notable observation, rumour has always been that the GReddy intakemanifolds caused cylinder 6 to lean out. It had always been speculation that perhaps that was incorrect, only because the flange angle direction and distance from the throttle body that i would receive the least amount of air. So far we have completed cylinder balance testing on our intakemanifolds, and the RB25DET GReddy. Before the test we were discussing what our expectation was going to be and we assumed well. First let's start with the GReddy manifold, as I would have assumed cylinder six was quite the opposite of what people always say. Number six was actually the cylinder that received the least amount of air movement. The cylinder that receive the majority was actually cylinder two followed by cylinder three. This can also be traced to its design where the throttle flange angle points directly on cylinder number two. Unfortunately thesemanifolds are not cast identically between cylinders and the runner lengths are different. I had never realised how much of a deviation that these manifolds had until now. It is actually a very poor design in respect to balancing. Our manifold did a better job of spreading the balance. The longer equal length CNC design off of the common collector provided for better distribution with a much lower deviated average between the cylinders. However the scenario was the same where the runner at the centre line of the throttle flange is the manifold that receives the most amount of air movement. However on this particular unit number five is the highest number and number one is the lowest. However the deviation to average is minimal in comparison. Otaku Garage RB25/RB26 Billet CNC Intake Manifold 200 CFM source Average flow 2950 feet per minute using , Highest (5) 3087 fpm, lowest (1) 2991 fpm Greddy gasket ported RB25 manifold 200 CFM source Average flow 2790 feet per minute using , Highest (2) 2988 fpm, lowest (6) 2690 fpm For the testing process that we used a calibrated 200 CFM electric motor fan and a eGMP rated and calibrated hot wire anemometer. The measurements were taking at each individual runner and recorded at a 10 second average. Each number was recorded three times. Pressure Tested at 50PSI no leaks or issues at all.

It will flutter in neutral with no load though

Do a revs check Do a Japanese odometer history check Ask questions about vehicle history, owners, why did it need a respray etc check steering wheel, carpet, handbrake, sills etc for wear and tear. Those seats aren't factory, see if you can get a look under the leather covers, if they are covers. Braided fuel lines? A few mods are questionable and need close inspection. The car looks to have been touched all over. It looks amazing for sure. But sometimes this can be a sign that it has had a few 'dodgy' mods done. Check the car with a fine tooth comb. Welcome to SAU

I've had a few, i noticed it on all. I tried a few things like what turbosmart suggest. I am using an automatic, so it could be more pronounced because of this.

But in all seriousness. I don't use any bov, never will again. They all leak and cause serious lack of power around 10-30% throttle. That's just my personal opinion

why would you block the bov? block the front of the turbo for ultimate sutututu

yep seems it is

Oem and splitfires are roughly the same price now days. Check out 'kudosmotorsport' they have some great gear and are very well priced. I too use 7es gapped to 0.8

Most aftermarket ecu's come with boost control functions. So buying one may be redundant. I have a turbosmart mbc if you were looking into winding more boost into your current car on the cheap. Pm me.

very interested. Great time in the land whale. What has been done?

That's extremely impressive on a std 26. I've only ever seen similar numbers on a 3l.

Yeah my bad. It is too.

From all the dyno sheets I've seen and have been overlaying. 80kw by 3k is what the stabdard 21u and highflow is doing. Not sure what you've been looking at.

Hmm 80kw by 3k isn't too bad. I'll do an overlay this arvo against a 21u highflow and 43g3.

What's the correction for speed to rpm on that dyno sheet?

Wut. Next you'll be telling us you have a recirc.

Wut. Next you'll be telling us you have a recirc.

i was going to say this as a joke. My god.

i believe if you unlug the brown plug for the auto it will be locked n 3rd? i have not tried this, but read that's what a lot of tuners in japan do. find the brown plug on the drivers side under the battery and trace the wires or see if it still plugged in

Hows the build been coming along? i always loved reading your updates

gotta catch em.... wait.

how old were the ad08's? what were they used for until you changed them? at half the price, the RS-RR's seem to be a clear winner.

Man that sucks! sanding up to wet 2k is the only way. That's if it even comes out. 240grit would have gone through the clear coat too.

love them Ryan!
