Yeah, that mans right. And as he reminds me every time hes under my bonnet he tells me I need to replace mine.

Re: Measurements MJET Induction

BTW!! Done it!!!

Will get airmass logs later on as going to Linz mums for mothers day.

Pics here though

Re: Measurements MJET Induction

looks quite professional considering you did it
does it sound same as adams?
and what difference you noticed if any yet?

Theres definitley more torque, its easier to wheelspin (Had to try), and the sound is now quieter that with it up high in the engine bay.

Better sounding when you can hear it too.

Re: Measurements MJET Induction

Right!!!

I've cleaned up all the data, removed obvious outliers and heres the results.

I'm more than mildly impressed with myself too





Theres a minmal difference between mine and the GSR though I've discovered recently that some of the GSR piping early on in the intake is of a slightly higher diameter than mine.

I've also noticed that the tube into the filter on mine is in a little to far and may be making a lip preventing airflow.

Just want to add to this quickly, theres a couple of considerations I would like to make clear. Firstly, my air filter has done 15,000 miles and is due for changing soon. This will restrict airflow. Secondly, the airflow to the MAF (where the readings are taken from) will be determined by the size of the piping, which in turn is defined by the size of the MAF housing, therefore we can't be far away from achieving maximum airflow to the MAF.

Good job though Sir, with only a little help Proof of the pudding will be on an RR

Getting a bit worried there Adam

Nah, I didn't slice my hand while fitting mine Just thought we could do with making some points clear, thats all.

Dave probably did though

LOL be good to get some sane day airflow and power readings GSR is deffo better designed so new filter should see that push ahead.

Hopefully sort a map tweak soon too

Re: Measurements MJET Induction

Good work. Proper scientific data rather than the usual "look my custom kit owns a GSR" some people come up with .

Quite impressive for a DIY kit.

But a DIY kit that looks awfully like the GSR variant

Re: Measurements MJET Induction

Like he said and I agree, theres only one way to design it on a GPS Mjet! . Space is so restrictive.

Re: Measurements MJET Induction

Cheers Chris!

Dont think it quite owns a GSR though Still, been great fun doing it.

We've also come across a cheap FMIC that we are gonna look to see how much effort it will be to fit.

From reading the posts on this and seeing the pics it looks very hard and complicated fitting an induction kit, even if i just got an off the shelf K&N one.

Would a pipercross/ K&N pannel filter have similar results as an induction kit ? Not to worryed about power increases but i would like to hear the engine and turb a bit more.

Will make no difference to the noise I don't think. Easy way of doing it is buying the GSR version of the kit, which is just bolt on. However, its not available at the moment

bugger always the way

I agree here, looking and the unneccesary bends and closing of the intake at some points as well as the oversize filter housing I'd say the stock intake is not designed to intake an optimal amount of air but yet to restrict as much noise as possible.

A higher flowing cotton filter make make a tiny bit more suction noise as air is drawn in faster but I wouldn't hold out for it. Performance will also take a slight increase too.

K&N are selling an induction kit for the mjet for about £80-£90, have any members used this induction kit and if so any gd ?

By the look of the K&N one it must bolt on before the mass air sensor so it chould be easy to fit.

Look back in this thread, Alex used a K&N style version for a short while.
