Hi Everyone,

Just need a little technical support, my GTR is running the standard airbox with a K&N filter. My mechanic is telling me to go for some pods and get rid of the factory airbox.

My car already has an HKS drag intercooler and 3.5 inch exhaust from the turbo. I have been told that the only thing letting the car down is its breathing ability and that I should expect a noticable difference.

Any advice would be greatly appreciated

:(

If u do make sure you build some type of cold air intake (see: forced induction area), otherwise you're just going to be sucking in warm air which may give you worse performance.

Some argue pods are a waste of time compared to a good panel filter, but they sound better :(

Did any of those GTR's have any mods to their standard airbox,

extra cold air feeds running into their standard box or airflow meters??

No. Because of the way the airbox feeds from the front of the bonnet anyway, it was cold air already feeding to the turbos.

Leewah,

I guess what I'm trying to find out is if the standard box provides enough air to the turbos given the mods I have, or would an additional air supply be benificial, say for example if I added another cold air feed from the front bar into the standard box.

Or would that be over kill ??

Cheers

There is no real such thing as overkill when it comes to feeding the turbo cold air. What you need to try to accomplish is giving the turbo as much air as possible as long as the air is cold and directed in a straight line. Turbulant airflow has a very negative effect on the effectivness on a turbo. We found a 4 rwkw loss by simply removing the air pod. We found that the air pod directed airflow in a less turbulant direction so we left it on.

hehe all i can say is if u slap on that pod go get an engeneers certificate for it or when u get pulled over the nice little men in blue will be putting a nice little yellow sticker on your windscreen, and acting as if there mechanics when there telling you to put back your origanal air filter lol :) good luck mate you got to weigh up the for and against mate but id put one on anyway :D

and if your going to do it do it proply with the right filter dont get some REPCO $5 filter just to save money get quality stuff its enhances the performances and last longer as they say you get what you pay for

I think I will leave the box standard and try to feed it more air through the front bar.  

If anyone had done/tried this on a GTR I would love to know !

Thanks for the help

I know a couple people both in GTRs who run a standard airbox and his best time so far is 11.4@124MPH

Thanks everyone,

Thats the great thing about these forums you can chat with people who have been there and done it rather then taking the advise of a mechanic who wants to make more money !!

I'm going to stick with the standard box and get my hands on some cam gears next !!

I will probably need some more help when I get closer to buying them.

Cheers

    • Hmmm. that's a tough one. There's a lot of history bundled up in that lot. Perhaps instead we can create a new pinned thread, called "Legacy Pinned Threads" and provide links to the these ones that will be unpinned in there. And maybe put the names of the pinned threads that are linked inside in the tags so they can seen from the outside? Or something like? I mean, it's half a step back towards having a more complicated forum structure, without actually having it. But there's a reason that heirarchical architectures exist. They are logical, and if executed properly, make it easy to find something without having any upfront knowledge of where it would be , and without using a search function.

    • It's all about selling non-compliant emmisions stuff, and things like tuning stuff that makes your car have more emmisions, a very small percentage of modifications and tuning go into race cars, the vast majority of tuning and mods, like catless exhausts, or non-compliant cats, go into street cars with registration  Like a gun shop can only sell to someone with a gun licence, if they don't, they are fined and even jailed, and whilst a gun is totally different to a tune, or a catless exhaust, they are still illegal for a street car As for customers, it easy, they send a letter and tell them to show up for an inspection, like if someone says your car is to loud now, if they don't show up for the test, they can cancel rego, just like not paying a traffic fine This has been happening for years overseas in other countries  I'm in no way happy about it, but, I think there is definitely writing on the wall for modern cars with emissions standards, which will effect tuning shops, parts suppliers and end users And like other countries around the world, it is the government's that makes the rules and regulations for street cars with rego What would happen to a tuner or workshop if they were investigated about turning off stuff in a ECU IRT emmisions stuff like engine check lights for cats, or removing cats, or putting in a lower cell cat, this is apparently all illegal IAW modifications to registered cars, or, retuning the car so that with even stock emmision stuff still installed, but due to the tuning, or parts, like bigger cam shafts, it will now not pass the emmisions test Yes, I am going into a rabbit hole, but going off what other countries are doing IRT everything related to emmisions........cars, trucks, manufacturing, mining, modified vehicles are a easy target Meh, time will tell how it goes either way

    • Just wanted to share the recent dyno results on my car. 20lbs of boost on pump gas. Pulled the fuse on the AWD so it was only rear wheels on the dyno. It made 484 hp at the wheels. I asked the tuner to see if we could do something so it breaks the 500hp level, but he said that we were maxxed out on pump gas. If i wanted to make more power, id have to go to E85.      8739a97a-9408-4eeb-b769-108ff1678736.mp4
