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

    • Yeah 98 for me, and 6.7/100 was my actual usage. On the downside the bloody thing still isn't running properly but at least they hybrid system is happy now. It starts but missfires like a bastard, and isn't throwing any code except "missfire". Thanks scoop. I did notice the AFMs are reading quite different at idle 1.33v and 1.67v so 25% variance (and have both changed and swapped them, the issue stays on the driver's side afm) so I'm looking for exhaust restriction (mouse nest?), compression issue or (hopefully not, no physical damage seen) wiring issue. Throttle might also be an issue but that is harder because you can't swap them side to side and not cheap to fire the parts cannon at.
    • I hope you're right and it somehow justifies it's existence!
    • actually, I've had one of those for a while and it gets more use than you'd think. Yes catching subframes, engines etc coming out under a car on a hoist, but also getting heavy stuff on shelving (to a certain height) without a forklift, holding the fuga's hybrid battery....like many good tools you'll find the jobs for it once you have it
    • Right, so God, it's been nearly 12 months since my last confession....  The main confession is I'm a horrible car modifier (amongst other things).  Obviously the pool was a massive distraction for the entirety of last year but really doesn't excuse me for doing nothing at all on the car for this year.  To be honest this year was a mental break to get over the extreme mental torment and pressure I put myself through putting the pool in!  It really was a slog.  The pool is still not completely finished but it might never be....  The kids love it and the wifey and I love it so mission success! I have spent a grand total of 30 minutes working on the car since when I commenced on the pool.  I just have not had a spare brain cell to be able to focus on it.  The thought of working on it just seems abhorrent to be honest.  My heart is just not into it.  Yet..... What I have done is decide that I'm a clown to not paint ALL of the underside of the car while I'm at it.  Originally I was stopping at the start of the rear subframe to then "get back to it later on once I'm ready".  Let's be honest, later on might never happen so may as well keep diving in!  I'm already balls deep so may as well go a bit deeper! So......  I've just purchased a hydraulic scissor lift table to be able to take the rear subframe out as a whole unit without having to dick around with jack stands rolling around on the ground.  Us 6' 8" blokes don't operate well at ground level! One of these- Anyway, will the investment in an expensive tool that I'll probably only ever use for one job motivate me to crack on?  Only time will tell..... Wish me luck!
    • Yeah the ACL and similar formable heat shielding materials are really nice. But most people do not have the patience or talent to do a good job like that. Almost anything is better than nothing though. Even if you didn't form it closely like that and just had a slab of it slipped in between the manifold and somewhere/thing you wanted to protect, you would gain benefit. There has to be a market opportunity for people like Artec to make formed heatshields to suit their cast manifolds. The fact that they are cast means that they are consistently the exact same dimensions and they could add bosses to the castings like you see on stockers to allow heat shields to be firmly attached yet floating away from the manifold itself.
