ITG maxogen - new enclosed filter information.
R-tech-Nick:
I have not see much losses with the stock intake and a good panel filter, if you think about it its the same setup on the S3 at 265bhp stock and 300bhp just from a stage 1 map using the stock paper filters.
We have done lots of testing for filter companies over the years and have seen little gains from induction kits (we upset them and they never came back as we did not give them the 12-22bhp gain on testing like the superchips dyno.... :stupid:), only when pushing turbos hard at stage2 and above is when we started to see nice "peak" power gains from induction kits over the oem setups.
At stage 1 k03 TFSi tuning you need to be looking at reducing exhaust back pressures first, just by removing the pre-cat you "could" gain 10bhp peak power and upto 15bhp in the midrange, get a sports cat fitted and you could be seeing gains of 20+bhp at points on a dyno graph.
Another way to gain power from flow is reduce the pressure drop between the turbo outlet and inlet manifold, getting outlet and inlet pressures close to each other by just 1-2psi could easy gain 10-15 bhp at points. Higher flow intercoolers and bigger charge pipes.

Nick. your supposed to be on holiday now. :signLOL: log off and start relaxing.
Well as you know i've had the pre cat knocked out now so that should have improved things a bit.
My exhaust is still sooting up pretty quickly though so perhaps still over fuelling?
If im not going to see much of a gain with any intake then I might save some money and go back to the stock set up.
Shame though when everyone seems to say what a beneficial mod having an aftermarket intake is.

totally agree with Nick, only really felt the benefits from the ITG when stage 2+, and higher up te rev range at the expense of low down grunt

I have revo stage 1 and have had my (open) ITG fitted for a week now. You cant tell me there are are little gains to be had as I have noticed a big difference , especialy mid range.

They will aways soot up a little at stage1 power as the "Lambdasoll für Bauteileschutz" maps are still in play and to be use to dump fuel as part of thermal component protection, which mean when giving the car some hard beans the lambda with drop to the richer side around 0.79 0.81 to cool the combustion at a compromise to power. Only when the main cat gets removed and better charge cooling gets added then the lambda mapping is aimed more towards power by running around 0.84 - 0.85. At stage1 its a fine art to get the balance right of all conditions.
I will make sure we have lots of time booked for you in the workshop, we can test many things on the dyno if needed to see whats worth doing at stage 1
ps
Wife is packing now... I have fitted the Halfords roof box to put the kids in..... Heading down south about 10am tomorrow.. :laugh:
