Ok I am looking at putting cold air induction in my GT. I have searched and the only thing which i have turned up is 3 inch aluminium piping and a bendable plastic called flexipipe available from supercheap auto.

I understand the principles behind codl air induction but i cant see how i am going to get 3 inches of piping behind my fog lights! i could possibly run it through the hole in the side of the chassis.

oh and if i was going to do it i was going to take the pipe from the TBI how or where do i mount the MAF???

any ideas/tips would be appreciated cuz fiting is looking like it is going to be difficult

Dyno results, and tests, result in the further u place the maf from the TB the more "power" you recieve, as for the cold air induction, im not sure, maybe just pod it (taking away standerd airbox) and getting a Cold air kit (heatshield) i just run a K&N in the stock airbox runs good, i have it coming straight from wheel arch, with that restrictive tank part removed like 3/4 of the members here good luck

Check out the articles. there is a nice one with pictures detailig how to do it

not exactly what i was talking about. I want to move the pod filter down next to the bumper... or in that neat space in the article you were talking about

I have the stock air box with a hi flo element, the air box uses the stock nozzle thing that goes into the gaurd, i got a bit of flexi pipe and tightned it over the nozzle, brought it down and bent it out so it went thru and sat in the gap behind the front bumper.

didnt work too well there was a li lbit of hesitation so i jsut have the pipe sittn ther feeding the stock box, works well enoguh for now

Goin to out some holes in the stock box for a bit more breathing

nah not interested in a snorkel.. i am maybe considering getting one off suzukird.com but then i have to get it shipped.

ive got K&N pod with some PVC pipe with 2 elbow joints and run it through the hole next to ur air box and out the bottom. the pod becomes dirty quicker tho, i dont really no how to stop that tho but yeah

Good Luck!

Talk to Paul now. ;)

hahah browsed some internet links supplied by Mr OzMidnight this morning...went outside with no more than a hacksaw and about...10mins? now my induction noise is sooooo nice! and my car pulls so much harder hehe

Look and learn! http://www.planetsoarer.com/BFI3/bfi3.htm yes its a soarer but the principals are the same post your results

Weird the stuff you learn when you look hard enough in places other than just one! Interesting how the open pods are rated on the site. Damn good tech info there as they back up their stuff with proof, rather than just hearsay or saying "it feels faster".

erm i have air con so that will make it a little difficult i am thinking

hey paul can u plz send me pics of ur intake? im curious as to how u did it

me too plz

Personally i would stick with the stock setup but buy a K&N filter, not sure about the MKIII's but the MKII's came with CAI.

This is an interesting mod, thinking about it myself

are there legalities with tampering with the airbox?

what purpose does the stock box serve other that to restrict the engine? why did suzuki make the intake for it so restrictive?

Thanx

Now now, if suzuki hi flow'd the box themselves you wouldnt be able to do it now would you?

look on the teamsoarer airbox pics, basically anyhting that opens up the front of the box

The design is not that bad (when comapred to some others) and is mostly to remove the induction noise. I have not seen any tests that prove the design is 'very restrictive'. The DOHC was designed about 1985 and the Suzuki Engineers got a lot of things very right. Some of their ideas (like the CAI) were not adopted by other manufacturers for many years. Even the SOHC '83 Swift / Barina has a simplistic CAI standard - needs a larger surface area for the CAI intake but that is about all.

On MK1 GTi's, the intake is inside the wheelarch behind the light. The plastic liner above the wheel seperates the airspace so only clean air from the front goes through to the filter inlet. Only 'problem' is the pipe from the wheelarch to the base of the filter housing is a little small but is very easy to replace with a bigger inlet pipe. The filter also has to be cleaned more often because of the direct path of air to filter.

On MK3 GTi's, that same space has an irregular shaped plastic box that acts as a silencer (just like an exhaust muffler), water seperator and smooths out the flow of air. Its main problem is the lenght of the intake from the front to the filter - however, once moving, the box is full of air and the filter is drawing from the air pool in the box so the intake length appears to be short and the air turbulance is gone. Smooth air across the AFM makes for more accurate air measurements for the ECU. The filter will knock some of the big bumps out of turbulant air but it can not smooth it out. You can pass a lot more air through a tube if all the air is flowing in the same direction.

These intakes are well designed first generation CAI's. With a couple of miss-guided mods they can also be made to perform very badly - the hot-air filter pod in the engine bay is one.
By now most people will have followed the link to the Soarer article. The author mentions air flow rates, ram tubes, flow restrictions ...... Get a copy of 21st Century Performance by Australian author Julian Edgar (from the library or subscribe on-line). The book has performance design details on all sections of a car and a very comprehensive setion on air boxes and how to test the air flow rates, use ram tubes, design and build air boxes ......... all the bits mentioned in the Soarer article and anything else you could possibly need to know about performance design changes to a car.

Julian Edgar writes for Autospeed - http://www.autospeed.com and his book is available at most good Technical / Automotive bookstores.

Interestingly, same guy used the term "wankers" and Swift owners in the same sentence....back when he ran his modified Liberty RS turbo - the same one that lapped Mallala and other circuits slower than GTP - basically stock engined - GTi's. :D A later greater tech author called him out on it. But yes, some of his tech articles are very decent.

a simple and effective way of modifying the stock airbox is to drill holes in the front cover to facilitate intake of air reaching the air intake. this mod also makes a good induction noise when coupled with a K&N replacement filter.

i just tested my kilometres. without hose i got 450kms to a tank, with hose i got 480km to a tank. not bad, and that was me having a heavy foot, slipping clutch and lots of a/c.
