Symptoms I am experiencing are, very hesitant under anything other that gentle throttle, check engine lamp up, error 23 on diagnostic, MAF sensor! I had an HKS panel filter on my last scoob, absolutely no problem 20K miles+. How much for a Maf sensor?

Finally went for the HKS (green was all I could get) - oh well it doesn't match my car or my watch.. Let just hope it does the trick.
I will post my view on what I think to it..

Hi Stef,
Sorry for the delay in replying.
Difference between our K&N and the original is that the only part of the K&N that we use is the filter. The mounting brackets pipes etc are all custom. For 2 reasons. First of all to stop vibration and secondly to improve airflow. the original pipe restricts airflow by reducing the size of the pipe by about 4mm all round. Significant believe it or not.
If you take off the original pipe containing the MAF sensor and look through it at the filter you'll see what I mean.
Hope this helps,
Paul.

Paul,
How much is your system how and have you got one in stock, Apparently there are no K&N filters to fit a scooby in the country at the moment, K***nor have the last one on order which should be coming my way, been waiting two weeks so far!! If you have one in stock you have an order Paul,
MY97 UK with latter style front end which means it has latter style standard induction?
Yes/no I'm sure you know which one will fit.

Well got the HKS fitted today. Wowww, the car spins right round to 7000rpm easily and then in 2nd and so... very impressed..
One thing that is concerning me is that when lifting off at about 2000-3000rpm I get a noise, almost like a dump valve sound but a deeper noise. Its like fluttering / chattering and is quite load... Its not the dump valve cos I can still hear that at higher revs and this noise comes from the drivers side of the car..
Does anyone know if this is normal?? I was expecting the extra noise when I floor it but not when I let off at low'ish revs. If it is normal then I think that it will take some getting used to but the smile on my face at the moment is helping me to forget it...
Cheers

That is related to the dump valve, there is pressure in the intercooler at very low revs ... what you hear is the chitter of the pressure coming back through the turbo, the spring on the MY98 dump valve is a bit stronger than other MY's and so its more noticeable.

OK Stef, Let me try to explain.
I wasn't very clear on this. My last car was a 99 reg but was a MY98 with the old type hot wire MAF sensor so it wasn't as prone to damage as the newer models.
The induction kit that we sell is very different from a standard K&N induction kit. the only part of by K&N used is a very large cone. It has an internal diameter of 6" compared with almost half this for a standard induction kit. The piping is all made by STI. So it's a kind of STI come K&N. The full kit by STI is mad money so to reduce cost we use the K&N filter element.
We guarantee an increase and guarantee your MAF sensor for 12 months. I have researched this MAF failure problem extensively in the last few months due to 2 failures on my own car. I concluded that there were 2 reasons for the failures
1) due to minute particles getting through and damaging the sensor
2) Due to turbulence caused by uneven airflow sometimes causing the MAF sensor to "bend" in the wrong direction.
Some people have reported their car going slower after an induction kit was fitted. This is quite possible due to the MAF sensor getting incorrect readings due to turbulence and incorrect air flow.
With our system the Air is smoothed out before it hits the MAF. We believe in our system hence the guarantee.
When someone comes into the garage looking for an induction kit I offer them both kits, an original K&N and our version. Still haven't sold an original yet although our version is almost twice the cost.
Hope this answers some of the questions.
Paul.

What kits were you running when your MAF sensors failed then? I presume they weren't K&N as you say your failures were caused by minute particles getting through and bad airflow. How exactly did you come to these conclusions? Most other MAF failures were linked to excessive vibration.

Ok Stef,
You want the gorey details then???
When my Maf sensor failed the first time I was using a panel Ramair filter. Due to overoiling or whatever, some oil got sucked through the wrong side of the filter and contaminated the sensor. I tried cleaning it but it was damaged. Replaced.
Second time was after about 800 miles with a pipercross induction kit. This time the maf sensor was completely broken. What started me thinking was on examination I noticed that the maf sensor was "bent" forward and not back as if it had been hit by a piece of grit or whatever. So I conducted a little experiment........
I stuck a tiny loadcell on the side of the inner tube near the maf sensor. It was about an inch long and was used in a lab scales.
im sure you know how this works but for those who dont........ When the loadcell bends it sends an electrical signal to a scales. the voltage is directly proportional to the amount of bend on the cell.
I calibrated the scales to read 0 on idle and took it from there. It wasn't very stable due to vibration but it gave an indication of the airflow direction.
It was noticed that with the induction kit fitted on full acceleration the scales read anywhere from +10V to minus 5V. indicating that the airflow wasn't constant. The maf sensor obviously gets the same reading. Hence with someinduction kits the car seems slower as the correct fuelling is not being given.
Our Kit smooths out the airflow and reduces the turbulence. Of course the MAF sensor failures can also be down to poor filtration and vibration. I have almost 20 kits sold so far and no problems with any of them. A number of rally teams also use our inductions as well as a lot of our other products and again without problems.
We stand by our stuff. Simple as that. If it's not good enough we don't sell it.
Hope this sheds a little light on the subject.

Cheers Paul.
I was just trying to find out whether any standard K&N kits had suffered any problems, and it seems they haven't.
Did you do airflow tests on these, or just PX?
Cheers.

Paul,
Any chance of getting one before the 27th(Oulton), I would like to try it but double the price it is a little hard to swallow having not seen it, Perhaps we could then compare on the 27th Stef....

Hi Mark,
I can send you a kit on Monday if you like.
We can also supply the original K&N induction kits as well if your looking at price. But if it's performance you want then it has to be the Mac's Power version
As I mentioned to you earlier all our mail order stuff comes with a 10 day refund period.
In this case I'll supply a kit on one condition? That you post a full review good/bad here on Scoobynet?
e-mail me and let me know. I'll need CC details but not by e-mail. In this case I will make no charge until after the 10 days. I think that's fair enough?
Let me know asap.

Stef,
I've never seen the GGR kit before but I just had a quick look at their website. Looks kind of similar. Except out bits are branded STI. Cone looks similar though. What price are the GGR units?
Mark,
You can call me on 00353 86 8797512
We're in Clane in Co.Kildare about 20 miles from Dublin. Look me up sometime when you are over. I'm in Dublin nearly every day so you I can meet you if you like?
