MAF kit fitted....944S2..

[Big Dave]

Ok folks i took the plunge this week + ordered a MAF kit from Andrew [ Promax]..For a 944S2 ..91MY...
It arrived in double quick time..[][]
+ today it was fitted...
It took a little longer than 30mins as it says in the instructions,[ very clear buy the way],, but i was fitting some vacuum hoses aswell, + doing some tidying up also...
Now to the test drive....[][][]

Well YES it does improve the drivability of the car....[][][]
It "seems" to want to "go" more + is more urgent , when you push the loud pedal,, ie things happen both smoother + a tad quicker...The idle is also dead level, not the usual fluctuations...[][]
For an increase in power..The jury is still out on that one ,, as it was WET on the road + lots of traffic...So i couldnt realy test it fully...
I will report back on that....[][][][]

All in all it looks a very profesional piece of kit, + looks like its always been there...It also saves a bit more weight as the AFM + assosiated braketry is quite heavy. so thats a +++++.

Thanks Andrew for the help + advice on the phone ,, greatly apreciated....[][][]

Great news Dave [8D]

If you don't get it Dyno'd soon I look forward to seeing it at next years 944 Dyno Day

Andrew,

Have you got any dyno figures for either the Turbo or S2 with the MAF kit? Are you going to get some?

Is this a true out of the box plug and play item? What about getting the mix set as the mixture set up was a screw on the AFM. Wont you have to set up the mix once the MAF kit has been installed?

If I were to go the whole hog with the 'Performance Kit' rather than just the bare MAF kit, I am presuming it would be sensible to make some other amendments/refreshments to the car, to prevent anything going badly wrong at higher levels of boost. Can anyone suggest the minimum steps I would need to take? I'm thinking stuff like a new head gasket.

 

[Diver944]

Dan, historically as soon as we start significantly upping the boost on our cars then the headgasket finally gives up the ghost. This is not because the car can't take it but purely because the gasket is old and finally wears out when more boost is introduced. A lot of work has been put in to Andrews aftermarket chips so that the AFR is safe and doesn't run lean (causing the heat that is so damaging to the gasket)

My car had been running with the equivalent of the stage 2 kit at 15psi for over 30,000 miles with no problems on road or track (dyno'd at 283 bhp). However, I had been planning to change the head gasket as a precautionary measure at its next service and then start running at 18psi with a Greddy electronic boost controller. At least then I should have got another 15 years or so

One question - my engine runs quite rough when maintaining speed at exactly 2100rpm in any gear (though most common is 3rd gear in a 30mph limit). Have you heard of similar problems, and will the MAF kit likely fix this problem?

Nice - does it affect insurance quotes with a MAF added?

 

[sawood12]

Paul - i'm glad someone agrees with me. I'm of the mind that i'd rather replace things in advance of them failing because if you are a few hundred miles away from home when it goes its a real pain in the bum. I'm also of the mind that with wide fire or Cometic gaskets around you may as well replace with these rather than standard. Only problem is it's a pretty pricey job and not one I wish to tackle myself.

Andrew - if the off-the-shelf chips like the one included in your stage 2 kit, are so safe then why would anyone need an AFR gauge? I always thought kit like this was really for the had core modders like Fen? With me being a relative whimp in the modding stakes what would I do if the AFR gauge suddently started to report mixtures that are too high or too low once I get round to ordering and fitting your chip??

however, it IS classed as an engine performance modification (isn't that the whole point of the "other" MAF thread to show the performance gains?), and you should check with your insurer beforehand.

Sorry Andrew, but that's extremely irresponsible of you to say that.

 

[Guest]

I know that, but to say it's a replacement part is just not true. a replacement is a replacement. an addition of a part which replaces the original, even though it may not add performance, is not. it's wrong.

To say you never said not to tell your insurer is just being pedantic, and is NOT in keeping with what I would expect from the supplier of a performance enhancing modification. As I said, i was sorry that I had to point out that you should contact your insurer, and that you didn't think it was necessary.

 

[sawood12]

Andrew,
You've been having the insurance debate with Mike not me! I'd rather not be drawn into insurance debates and I think insurers are all robbing b@$tards and are unreasonable at every opportunity! (sorry to anyone on this thread who work in insurance but they tried to load my premium by 15% just because I had non-std wheels fitted).

Thanks for your advice on AFR guages. One more thing to add to the shopping list!!

Sorry Andrew, but that's extremely irresponsible of you to say that.

I had to call my insurance company to correct some errors on paperwork, so took the opportunity to ask where they (Adrian Flux) would stand on installing the MAF.
I explained that this is the modern equivalent of the existing system etc. etc.

As they deal with many companies, some as we know will not insure with any mod whatsoever where as others may put a premium on it and others may not. Ok so we know that.

If it did not increase BHP then in general there probably would not be a loading.
If it did increase BHP then there probably would be a loading.
If your car already had performance modifications then without doubt there would be a loading.

So clarity on added BHP or not seems key. That pendulum seems to swing.

One of the reasons I had to call was that in the mods section they had not put down my wheels. The agent on the phone as so many have asked "˜Are they or not the wheels the car left the factory with?' No, so it's a mod. Being Porsche wheels seemed to help. Anyway, I think it would be fair to say that this is how they look at things; an alteration to the original spec is an alteration/mod.

It would be interesting to hear from someone with one of these fitted to comment on this issue, from the horse's mouth. As I did ask earlier with no reply. The one/first post and timing of post has led me to believe he may have been one of Iggy Pop's band?

Devils Advocate
I guess the grey area surrounding self-promotion is now plain black and white.

 

[sawood12]

The rediculousness of the situation is that my insurance company wanted to load my premium by 15% for non-std wheels and another 15% for my SS backbox. As a comparison I looked at the insurance cost of a £30k 400BHP 911 turbo and it was about £20 more than my std 944 turbo, but with the extra 30% loading my £7k 944 turbo with non-std wheels and exhaust would be more expensive to insure than a £30k 400bhp 911 turbo. Where is the sense in that??? When I pointed this out to the 'oik' on the phone he agreed with me but the problem is you often don't have barganing power or the opportunity to reason with someone who can affect your premium because you are often dealing with a call centre. The call after mine was probably a British Gas one. I find that alot of these specialist insurance companies are not interested unless it is a 2nd car with a limited milage of 6k per year - so I don't qualify.

In my view unles they can justify the increased liklihood of you having a crash or the car getting nicked as a result of your mods through statistical analysis they shouldn't load your premium. I'd love to know how many of these chavved up Corsas you see buzzing around have all their mods declared??

 

[Peter Empson]

I phoned my insurers last week to declare the latest changes to my policy and they told me I already had the maximum allowed number of modifications... This is clearly crazy, I've only just begun []

I'm not sure about other insurers, but I seem to be getting hit for a £15 processing fee for mods that increase the premium, so upgrading in stages as I've been doing has ended up costing quite a few of the fees over the years. It's certainly something to watch for, making the grouping of work together the best way to go.

And whilst I'm airing gripes, why can't insurance companies educate their operatives so they know what basic technical terms mean??? How can you stand any chance of getting accurate policies if its impossible to relay the work done to someone who seemingly has never seen a car before?

Best regards,
Peter.
