ITG Airbox Development for E30

[M5pilot]

Been looking into ITG air filters.

ITG have many years of experience in Rally and Touring Car championships at world class levels.

Basically they know what they are talking about.

They are also a company who do proper research on every car they design products for. Everything is dyno tested and setup properly.

They have proven gains of upto 10bhp on some cars like the Rover ZS180 2.5 V6 and Lotus Elise S2 (which both have good intake designs to start with).

I am going to give ITG a 325i so that they can design a Carbon Airbox for it and give us near 10bhp increases.

But we arent just talking about BHP here, from all the dyno graphs ive seen there are excellent increases in torque.

The Cost!

What will these fantastic little things cost!! Around Ԛ£250 for a properly developed Carbox Airbox kit specific to E30 325i's.

If they can give us these sort of gains for Ԛ£250 then thats very good value for money I'd say.

8-10bhp for Ԛ£250.......thats impressive!

There's a guy on E36coupe that's fitted a gruppeM carbon airbox to an E30 325i, pretty straight foward too by the looks on it.

Won't these be anything like the pipercross viper? That's basically a carbon air filter box ain't it? I've heard nothing but negative comments about them.

[M5pilot]

Simon,

The pipercross range is just an empty box with a filter stuffed inside it. Theres no real design behind it at all.

The ITG has some sort of internal flow system and air trumpets which increase airflow.

I doubt very much a company like this would lie. You can actually go on thier website and they have a whole host of cars with dyno's done back to back on the same rolling road.

If they can prove the gains then there is no reason to doubt them.

I will certainly like to get a kit developed by them and if it works then its all good. If not then no harm done.

What I would like to know is ...... IF......they can build something for around Ԛ£250 and give gains of 12 bhp like on the vauxhall VX220 and other cars are people interested?

I dont think its alot of money if it really will give gains like that.

[SwirlyE30]

Ive got an IS lump to stick in my car, and want to go for somthin like a BMC induction kit, although id be up for this also. But i doubt its do'able for the is

[E30Adam]

Sal, need a test car?

[M5pilot]

Adam,

yours would be ideal test car as it has a new engine!

As for the iS, I think its well do able with the amount of space in the engine bay.

ITG gained 15 bhp on a 16V Ford Focus engine @ 6000 rpm, no reason why we cant give them an iS to develop it on.

Before going ahead with the iS it has to be confirmed how many iS owners would be up for buying this if the gains were good.

E30 M3 would also be an excellent choice.

Let me speak to them tommorrow and see how the react.

[Chaos]

Adam,

wudnt a standard or close to standard car be a better bet ?
as thats what most ppl wud have. no disrespect but adams is sposed to be pretty high state of tune so any figures gained on that wud be irrelevant to most ppl.

[CiLK_WuRM]

Same sort of gain on an Alpina 2.7?

[M5pilot]

I expect the gains on a C2 2.7 and a 325i are going to similar because they have the same intake.

Adam's car already has an ITG foam filter from what I know so the gains will be less.

Also fitted with a MAF so the fitment is going to be totally different to that of a AFM's car.

So, Chaos is very right here, a much more standard car would be required.

The only car I know of which is bog stock and makes over 165bhp is taxidriver's black touring. He would probably lend it to me for the purpose of this test.

If anyone has a 325i, no chips, no nothing which has a proven 170bhp then I need your car!

Obvioulsy I will only need it IF ITG agree to make us a kit.

[Karan]

will this be like a BMC?

[M5pilot]

Its Similar to the BMC in that its got a carbon air box.

After that the similarities end.

The product will be proven only when tested, at the moment the only I thing I have to go by is dyno's on other cars.

I will probably be doing a test on the BMC Airbox in the very near future.

yeh do a test on bmc... as it has an interesting internal design.... which roates the air on intake thus accelerating it

[E30Adam]

Good point chaos. Most people will have close to stock 325's so a totally stock 325i in good condition would be the best car to use for development.

[M5pilot]

I might use my own 325i Touring as it seems to be very quick for a stock car and it has no modifications other than a back box which in all honesty alot of people have already got.

I am going to take it to Bexleys to get it dyno'd along with Taxi Drivers car.

If one of them makes good power then I will start by adding parts to that and report back on the ACTUAL differences on the dyno.

UNfortunately this will only give an indication of differences at FULL THROTTLE. From Experience some modifications dont do a huge amount for when Full throttle is applied but do make a big big difference on part throttle driving. This can only be reported back with on the road performance.

Wathc this space!

[M5pilot]

I've just been on the phone to ITG.

ITG do some serious serious testing in order to produce a kit for any particular car.

One of the proceedures is to fit an Airtemp sensor to the stock car and measure temperatures under different driving conditions.

They then fit their kit and adjust where the air is being taken in until they get the lowest temp reading under the same different driving conditions.

So basically everything is done under real life conditions.

If they find that they can get a reduced air temp then they can be certain that a power increase will be there. If not then development stops or they start again.

If Lower temp is achieved they rolling road to see how much gain there is and if its a good gain they will go ahead and make the kit.

Obvioulsy this costs alot of money and alot of special tooling is required to make certain components.

In order to get anywhere I need 20 orders! If we can get these guys to give around 10bhp increases which they say is well possible and they will prove it, then its well worth it. Cost will be a more realistic Ԛ£400!!

I dont really know if I should go ahead with this as its alot of money for most people but the gains are also potentially very big in comparison to the money spent.

If people can spend Ԛ£400 + on exhausts that dont really give any more power at all then in my head it says people will spend somewhere it does make a big difference but Ive learnt it doesnt always work like that.

I need some sort of opinion from everyone if I should go ahead with this project.

[Karan]

but Sal... dont mean to pop ure balloon but thats a lot of money..... for a glorified air filter.....

[Jhonno]

yeah but if you spend Ԛ£250 on this.. Ԛ£400 on an exhaust Ԛ£55 on a chip and Ԛ£120 on a BBTB and saw near to 200bhp i reckon it would be money well spent.. thats not bad outlay for the BHP

however im am always dubious bout power claims from airfilters i'd like to see a back to back power run and 0-60, 1/4 mile..

yeh if it can give that mcuh power then its good

[M5pilot]

I really wish you would buy some glasses and read properly!

I have said above "Its alot of money".

Why do we always have to be so over sceptical anyway? They say they are only going to make if they get around that sort of BHP gain proven on the dyno.

I think thats fair play to be honest, they arent in the game of supplying goods which dont make gains so to say its a glorified airfilter is rather harsh.

Oh, and I will be testing the BMC in a week or so and we shall see if its a proper product or a carbon fibre biscuit tin.

LOL at the carbon fibre biscuit tin!!!

id like to see runs with an air filter and without to see how restrictive air filters actually are

Karan

[Jhonno]

without will show less power

[M5pilot]

If a company can back up their power claims with dyno print outs then there is no reason not to try it out. If those same gains are made on another dyno then its all good.

Intake/Airbox design is something that takes alot of time and development to get right, its great to see companies like these actually getting off their arse and starting from scratch and using a scientific method to do their analysis with and then putting it into practice.

No wonder they are a small company! They spend all their time developing stuff to make sure it works.

[Wilson325i]

Ԛ£40=1BHP is not bad

i think bexley charge Ԛ£60 for 1BHP

so if it is proven that you get stated BHP(8-10) then i will be up for it

[6potWil6pot]

Really wanna see if theres any gains with the BMC, i didnt notice much on my old car but i didnt drive on WOT that much!

[M5pilot]

ITG want me to place 20 orders to even carry out any development work.

So......19 more people required ...... LOL.......I feel this will be a long long wait!

I could just buy the airbox myself and experiment with airfeeds etc.

BMC will be tested when the Alpina goes for its final remap, hopefully it will give some gains.

Again, it really depends where the intake pipe is connected, this is really crucial.
