Hey guys and gals...

I don't know if there is another section I should be posting this to (or if anyone is keeping a tally of these numbers) but I went up to AMD in Bicester this weekend and had Geoff remap the ECU as well as the usual cat bypass. The numbers were as follows:

pre remap: 253 bhp corrected, 231nm torque ( I think, will confirm the torque number when I get home)
After remap and bypass: 277.5 bhp corrected, and again, I think 256nm torque.

I will confirm the torque figures once I get in this evening. (at work presently)
The car feels livelier. I have a lovely stretch of road which is just over a mile long, straight and a 70 mile-an-hour speed limit. I used to be able to watch the rev counter move round to the red line, but now it is all a bit more frenetic.
Also feels better at low speed, with less tendency to "hunt" at idle.

Also, thanks to the guys who posted the "changing of the headlight bulbs" trail. It took me 15 minutes yesterday and now I am the proud owner of blue-tinted headlights. (sad, I know, but they look better and perform significantly better than the old ones. Claimed 30% brighter-can't test, but it looks better.)

Now, just the RUF suspension kit to be installed on Wednesday this week and the beloved will be complete...(yeah, right!)

Cheers

I'm a bit cynical about these things - especially the before & after dyno plots - which are pretty easy to 'adjust'. But, I'm interested in the seat of the pants dyno - is the car quicker??

Also, let us know how the suspension upgrade goes as a few of us (me, Christer.....) are still looking into improving/lowering/stiffening the suspension.

 

John,

I am just as synical, and having annoyed all the tuners with tons of calls, having read all the forums, both this one and smartgroups, I decided it wasn't too bad a price to pay. It does definitely feel quicker. Not just quicker, but "stronger", I suppose, would be the best way to put it. It pulls really "strongly" now and sounds meaner. Even my wife (who is a bigger sceptic than anyone here - car is from a-to-b!!!) is impressed. Now THAT is the biggest result. She now has given up her idea of an MG and wants a Porsche - my Porsche, to be precise. Maybe, if she gets this one, I can buy me that 993 Turbo...Mmm

 

How much was the 'price to pay'??

I too have a wife to convince, but luckily she loves the black C2. She is a Merc CLK fan (doesn't have one yet), but she really likes 'our' car.

Like you, I have been sneaking a look at the 993 TT board - its a laugh to read guys trying to make a 450 HP car go faster!!!

You're also going for the RUF suspension. I'm thinking of just lowering mine with the H&R lowering springs. Let me know how your RUF thing works out.

 

John,

CLK??? Is that a real car. Only kidding - before all the merc owners flame me. It was about £600 inc vat. This included the cat bypass (£140 ex vat). Not bad.
The RUF is something I am really looking forward to as the car has it's original springs and dampers on, and they are feeling a little tired now. GT-One are doing it, so it should good. I will let you know on Wednesday night.
BTW, I think the 993 TT is probably the perfect shape. I know the 964 is more aerodynamic, but I love the TT shape, not the normal 993 shape, just that one. I think it's the whole ex-80's whaletail type thing that does it for me. Also 450 BHP. Mmmm boy-racers and 330 Ci owners (also include M3 and M5 owners in that!) beware. Why do these guys always want to race me??

 

Yep - would definitely be interested in the RUF kit feedback. Where did you buy the kit? What was included?

On the chip side, If I was doing this to gain power, I would get before and after RWHP only plots at an independent place as well as AMD's own one. As John says, it's a bit difficult to be sure of the actual improvement in output.

Christer

 

I'm also keen to hear about the RUF suspension - I'm at the early stages of the same thought process so any details as to what is included, things to watch out for anf your feedback (and ballpark price) would be GREAT!!!!!!

Thanks

 

Christer,

The RUF kit was purchased through GT-one. Check
/<a href="http://www.gt-one.co.uk" target="_blank">GT-one homepage</a>. They are installing it. I'm not sure on who the manufacturers are, but the thing that swayed it for me was the fact that all is included. Roll/sway bar, bushes, springs and dampers. PLUS the fact that you have components which were designed to work together, and it's from RUF!
I was thinking of going to JZ or another tuner for an independent dyno, but all the people I would be taking the car to, would be selling their own versions of the standard de-cat and remap, so how independent would they be?? Dunno, just my 2p worth.

Mark

 

Sorry all,

Thanks for the preliminary info - I too have researched the RUF kit thru GT One. Interestingly (or not), you will find that the RUF kit uses your existing front springs. They uprate your rear springs and provide you with new shocks all round. Then you get the 2 anti roll bars (I believe they are both adjustable). I haven't got any data as to the size of these roll bars.

If we compare the RUF approach to the rest - then RUF are the odd one out. Most other kits (at least the street kits) use 4 progressive springs and 4 uprated shocks. You can of course add RS antiroll bars to the setup at a later stage if you wish. At extra cost.

I would be very interested in more detailed feedback if you have it/or care(!) and possibly a ride in the car to see what it is like...

I have had an independant dyno run on my C2 today -result 296hp adjusted. I was unable to pick the car up today, hence i don`t have the dyno plot as yet.I hope to pick it up tomorrow evening and I will post the dyno result from today along with the original before and after AMD dyno plots.

 

Odd RUF comments:

A friend bought some RUF parts without doing the proper research and it didn't turn out well.

He has a 911SC with stiff torsion bars (like springs). He replaced his shocks with RUF shocks that are essentially re-valved Bilsteins with a RUF logo. They didn't match the torsion bars and it made for an unpredictable ride.

He also bought sway bars and they are not adjustable.

I'm sure that you guys are doing the proper research (in fact - you state that you are making all the right calls, etc) -
But I thought I'd just send in a statement of the obvious - that you should always check these things out first.

ps - the friend consulted a good independent mechanic and got the proper shocks installed, and now it handles very well...

In the US (and I would guess outside US too) you can have Bilsteins revalved to whatever you want for $55 plus shipping per shock/strut.

Tony the figure that I would be interested in is the Rear Wheel Horsepower. This is a much more accurate reading as there is no adjustment (read guessing) for powertrain losses, and the figures cannot be 'massaged' (well not that easily).

Look forward to hearing more from you.

But anyway,

 

They can be massaged if there are "temperature" corrections. Have seen plots from dynos in UK where the test temp has been over 30 degrees C - not in February it wasn't!!!! However, the corrected HP for temperature was a up a few HP!!!

But hey, I'm just cynical!! <img src="graemlins/c.gif" border="0" alt="[ouch]" /> <img src="graemlins/c.gif" border="0" alt="[ouch]" />
