does intake help much?

[SAUmember888]

Hi Guys,

I just bought an R33 GTS-T, It's completely stock. I cant afford any major mod at the moment. Just wondering would an intake alone help much in term of performance? because it normally should go with an exhaust system (like the car gotta be able to breath in and out well!)

If your talking about whacking a POD on, you'll probably actually get a negative effect if the car is stock. But go ahead & whack a POD on anyway coz its cool.... You dont wana be caught showing of your skyline & lifting up the bonnet without a POD under there do you?

y do u get a negative effect if its stock. can u explain?

[Pva_Glue]

After market pod will help you, I dont know why geno8r said its will have negetive effect? :rollseyes:

Just make sure its fine enough to filter out dirty air...

and depends on the road regulation, if you dotn have permit or if the pod is not securely attached to somewhere you would get defect "yellow sticker".

hope this helps.

Pods bring in more air, but hot air

Stock air boxes bring in less air, but colder air.

Pods are only good for turbo's sucking lots of air @ higher RPMs. If not flowing large amounts of air, best to have a cold air box around it, otherwise its just going to be sucking in hot air.

Pods can be Bad for lower speed, but good for higher speed RPMs.

Hot4s mag did an article on stock air boxes vs pod filters & modifying your stock air box by replacing the filter & cutting out some plastic restrictions will work better than a pod if your vehicle is stock, can all depend on the total setup like all things.

cheapest mod would be a turbo bleed valve about $100, turn the b00st up to 10 or 11 psi and enjoy

Get an Apexi filter or a K&N. Then run some 3"-4" dryer ducting from somewhere exposed in the front of the car, such as a fog light hole, up to the filter, essentially creating ram air. If you cant make it work, you dont want it bad enough, and yes, you'll notice the difference.

[geno8r]

Yeh, do a search on Cold Air Boxes, there's lots of good advice on making your own, & as fantasy said directing air up to your pod. I personally have not done it yet but will expect good results when i do.

I rarely go driving & nighttime but went driving last night when the air was all cold & DAM! My car was running the fastest i'ver ever felt, stock 7 psi felt like atleast 12psi during the day. Then when i upped it to 12psi, all i can say is fast... very very fast... So when i do get a CAI happening should be great for daily driving.

Along with what Duncan said about the bleed valve....If you simply turn up the boost with out increasing the amount of air that the engine takes in, the engine works much harder than it has to. You might even see bigger gains with the addition of a filter at stock boost levels as apposed to just turning up the boost without one. The addition of a filter may raise you boost a notch or two as well. Both a new filter, and upped boost would be even better.

um since we are talking induction here, what effect does changing the stock (plastic or rubber or whatever it is) intake pipe that runs from the air filter to the turbo to a metal one. Are there any real adavtanges that make the change worth it?

[Cubes]

When my R32 GTS-T had an exhaust, FMIC & 1bar of boost it made 164rwkw.

Slapping a pod on inbetween power runs showed absolutely zero power gain. If anything it lost something like .5rwkw down low.

Apparently the stock RB airbox is good up to around 400hp or ~200-230rwkw before it becomes a restriction.

[GTRman1992]

I have 260rwkw with stock air box and K&N panel filter.

[shif_tea]

but does it make the noise that my nasty HKS pod makes???? I think of it as a cheap substitute for a blow off valve

[GTRman1992]

Nope. No extra induction noise really.

[geno8r]

I gota K&N Pod, induction noise is very nice in the cold & yeh, you get that flutter noise too... But lets not get into that, theres another thread about that.

but yeh, the point is a panel filter for your stock air box is good!

Yes I had the pod on, then we wacked in some 3inch piping from the front bar (middle of winter mind you when it was done) and yeah, I REALLY noticed the difference that made, altho it probably wont make a lot of different on a dyno.

And yeah get a bleedvalve, mine cost $70, works a treat, holds boost perfectly, never spikes etc.

Keep the stock box. Get a GTR foam re usable 'Finer Filter' they have very good flow and do a good job cleaning the intake charge. As an addition to the stock cold air intake I cut another hole nearby and routed short piece of flex pipe to just behind the headlight to assist with air flow. Car really seems to accelerate and breathe better, and you're not sucking in hot air, that kills performance.
