The street testing of mods is a real joke! Do it right using a dyno with "before"
and "after: tests, i.e. ONLY one mod at a time and NOT all mixed. Using the
this thread's methodolgy, DOESN'T prove nor indicate anything.
Check out this website (www.systemsc.com) on the Problems page under
Performance Chips and the Technical page on Ignition Systems for some
info about chips. Also, go to www.andial.com on the FAQ page and read

Loren, I seem to recall you saying the same thing about someone's dyno results on another board. If chips were a sinking ship, you would drown before admiting the ship had a hole in it.
I am going to dyno with 4 different chips, GIAC, NBCD, Ruf, and stock. I was just supposed to wait until after I put 1,000 miles and had a valve readjust before doing so. I am at 680 now.
My goal was a sub 5 0 - 60 or else I was going to the Lenz system. I have a feeling I am very close to the hp of the Lenz system now. I will know soon enough.

There was a recent thread by Joe (Joey Bagadonuts) which, I'd highly recommend for assessing the impact of a combination of changes (including chip) on a more standard 964 motor than Doug's. While some of the participants in this thread contributed to that, for others here is the link.

To qualify the results requires both sets of mods. alone in isolation very little is gained.
The chip being the part that pulls all the parts together, as in the sum of all the parts is greater than the individual parts alone.

I cant understand the logic in thinking that the chip will pull all the modified parts together,Dougs modified parts with the standard chip produced a standard 0-60 time for a 964 cab.Doug does not acually know what if any significant mods have been done by the previous owner, with a standard 0-60 time with standard chip we can only sumise that the mods are not indeed that significant at all,but what we can see before are eyes is there was a huge difference when Doug fitted the RUF chip.

Andial is in the business of selling a very expensive engine upgrade. Naturally, they would have incentive to say that cheaper routes to increased hp are to some extent futile.
I had a stock 3.2 Carrera and I noticed an improvement in performance when adding a chip. Not a whole lot, but at least .2 range. Can you feel that difference by seat of the pants. I don't know, but some say they can.

Adrian,So youve taken your car apart and written a book about it,it does not qualify you for engine mod advice cos yours cars very stock isnt it?. You can say all you like that there's only a 10-15 bhp gain,it doesent work like that its where the power is concentrated to the rev range.
Let me tell about a pal of mine who's owns a 2.5 dse range rover who was dissapointed with sluggish engine response.I drove his car before and after the chip was fitted and with only the claimed 14 bhp chip gain
there was a huge difference to the acceleration.If your claims are true chip firms would have so many law suits against them that it would be pointless actually selling them.

The stock chip won`t take into account the modifications so there is no reason to believe the other mods would be effective without a rechip. It is possible that without the correct maps performance could be worse.
If your 964Cab is stock and does 0-60 in 5.5 then your a lucky man but that time isn`t consistant with the RWHP/weight ratio of a stock 964Cab. There was a thread awhile ago of UK listers measuring 0-60 with a G-tech and it is interesting to compare those times with 5.5s for a Cab.
I`d say Dougs times are consistant with his mods and the cost would be at $10k mark.

I am not by any means an expert on this issue, but it seemed like I was loosing power with the stock chip in the upper RPM range (last 1,000 RPMs). I though this could be attributable to back pressure issues now that I have a cat-by pass and no secondary muffler. Whether right or wrong, I had thought that the more aggressive mapping on the Ruf chip may have help out in the upper RPM range to compensate for back pressure issues. Something is working as the car definitely has tremendous pull now all the way up top the red line.

I believe Dougs car is not a lightweight and it would take serious power to get these times. 320 bhp is possible with the type of mods he has although if you wanted to be churlish you could argue the merits of data-loggers as measuing tools and the feasibility of acheiving 320+bhp. Doug has given this information in good faith and everyone can believe what they want.

Paul,
Think of it in a different light, singing for example.
There are many fine individual singers, all excel in their craft.
Put them together in a choir, making sure the individuals have the neccessary requirements to sing their part, and the result will be a full bodied harmonious song, with a much better range and depth than the individual parts on their own.
Kevin.

Dear Doug,
I am seriously impressed and I have save the images of your runs and I am going to take them to show to Alois Ruf when I visit him either this week or early next week. I know he will also be very happy for you.
It doesn't matter how you go there (cause I wasn't paying) but you have achieved something positive and reckon it is really kool.
This is a victory for DIY Power!!!!!

Dear Doug,
What I like about your work is that you are working with what you have. That is what most of us have to do. Your work has actually provided a great checklist of what can be done and some of the steps required to make it happen. It also provides a great example of the real costs involved. This is what Rennlist is all about.
May I suggest that you write this up in a flowing format and then we can get it posted to the tech section and maybe on a couple of other sites as a reference point. We can tell people, here is a real world story from 2003/4 of what you have to do. Or you can give me all the bits and I will knock something up for you to sign.
