993 to 300 bhp at Ninemeister

[Mario149]

Hi all

Firstly, I just wanted to say hello after an absence of 3 years! With the kind help of one of the moderators (Paul, many thanks again) I've managed to get my old profile re-enabled albeit with a slightly different user name (I used to be mt0859) that now matches my PH, ClubScud and Fchat ones! I used to lurk and post a bit on the 996 section when I had my C4S, but have recently come back to the Porsche fold and got myself a 993 Cab so will likely hang around here now

So, my query was: has anyone here had 9M's 300bhp tweaks done to their car? : "Up to 300hp with Motronic ECU, cat bypass, KN air filter, ECU live remap"

If so, I was wondering how you're finding it? I emailed them and Colin replied with useful info, it seems the option I mentioned above is £1k + VAT which seems pretty good value for what is at least on paper a 10%+ power hike, but it'd be good to know if people on here had real world experience of it and could recommend it?

Sounds good - presumably based on a non-varioram car (i.e. nominal 272 bhp to around 300)?
Need a sound engine to improve upon, though.[] Interesting.

Chipwizard got my 94 993 to 300bhp with just a re-map for around £350, I believe now its around £400, including live rolling road! Something to think about! Was freezing cold when being done, which helps the figures a bit. Im not saying Nineminster isnt worth the money, just offering an alternative, wayne takes some beating!

Cheers

Mike

Thanks for the info Mike. Did they dyno the car before? If so, what was it showing?

 

[D Ward]

That does sound pretty good value for that sort of gain especially on a normally aspirated car. getting rid of the cat is always a good move, from the extra power gain, nicer engine note, better fuel economy and the losing of several Kg's hanging right out over the back etc

Not so sure I would wants the k & n filter if its the oiled type, for the reasons mentioned on here many times before

 

[Mike M]

Yeah, dyno before and after as:

Before 281.1 bhp - 258.1 lb ft
After 300.5 bhp - 271.7 lbft

Ambient temp of 47F.

Could you give me the abbreviated version?!

I don't suppose you have graphs? I'm most interested in the torque change and where in the revs you gain []

 

[Mike M]

Yes I have the graphs, Ill scan them in later on in the week and e-mail them to you or see if I can manage to upload them here.

Inside your mass airflow meter is a thin platinum coated wire stretched across the incoming air flow, the wire has an electric current passed through it, heating the wire.
The car dme measures the amount of air coming in via the resistance of the wire, the air flowing across hot wire cools it and the resistance changes, from that the dme works out how much fuel to add etc (the dme takes reading from other sensors as well)
Anyway by adding an oiled air filter, small amounts of oil can coat the platinum wire and give an inaccurate resistance reading and you can guess the rest, poor running etc

I believe the standard Porsche air filter is very good and easily fine up to another 50 bhp so in your case you probably dont need to change you air intake arangements

I would say that the air filter on 993s do get dirty very quickly, don't know if its cos the engine is at the back or the because the clutch vents into it, but i change mine more frequently than it says in the service manual

Ah, makes sense, thanks for explaining.

Hi and welcome.

If you have a look at the "NineMeister Dyno Day Results & Graphs" thread (993 forum, "top" items) - you will see some data from when the register spent a day with Colin checking our cars out on his dyno. As you will see, how much effort you need to use to reach 300 bhp depends on your car! There's quite a variation between cars (some with apparently no previous tweaking). For example my own has had no tuning done on it - OK some previous owner could have tweaked it, but there is nothing in the receipts file and I'm sure there would be because all 3 previous owners were pretty keen on keeping even the most minor receipt.

So worth asking by how much they can increase the BHP rather than to what top level.

+1 for Chip Wizzard. Wayne re-mapped my car to 305bhp. It already had the cat bypass mod done. He tested the car before hand and it was producing bang on the standard 285bhp for a varioram car.

 

[Mario149]

Does anyone have contact details for Chip Wizard? I can't seem to find a website....

 

[szklarek]

These are the details I have on file (it's on my list of things to do - after I had RS cams, RSR boxes etc fitted). Apparently he gets very busy as the race season approaches.

If they've changed perhaps you could post?

Wayne can do what u want with one hand tied behind his back.....hes done so many without problem
He is also capable through his wide experience of evaluatimg ur car beforehand and sorting any problems .......................ur out come will definitely depend on staet of car now
FWIW ...............HE SORTED BOTH MY 993 GT2 S AND MY 993 CUP CAR ................WATCHED HIM IMPROVE MID RANGE ON BASIC 993 S ALMOST BEYOND CREDENCE

A thousand pounds sounds like too much , I agree with other posters in that the standard air filter is the same one used on the turbo model boasting 408 bhp or more with a power kit upgrade, consensus is an oiled cotton filter is a risk, and not worth taking given the power gains proven with it. I don't see a decat as a good road going mod, it could be a pain every time time you mot the car, now the 993 can just about pass an mot without a cat ( I look after 1 M150 (leaded fuel/no cat) example and its a bit of a struggle but it does pass the mot. current legislation according to my mot man is that the car must appear to have a cat to pass an mot regardless of the actual emissions value. 200 cell cats conversion is a good mod however, not sure of exact power gains from that mod alone, i would think that a chipwizards remap on an otherwise healthy engine for about half the cost would be the way to go.

Mario I am interested to know what you thought about your C4S?
Thanks

Just to clarify, it was a 996 C4S! But if that's the one you're asking about....

I really enjoyed it overall.

Positives:
IMO it's the best looking 996 other than the GT2/3
Running costs were pretty sensible for me (but this was when it was only 7 years old)
Was great as a daily drive

Negatives:
Rather heavy, the extra 125kg or so over a C2 makes a noticeable difference when you've only got 320bhp
Over-tyred for the engine IMO
Not really sold on the 4WD, mine seemed to always understeer on track unless you really provoked it, at which point PSM would save your ass if it was on, or if off, you'd spin. But I never had its geo checked and I'm no driving god so it could have been that and I'm sure you could get it adjusted to your tastes if need be
