Guys

thank you very much for the nice words. The 911 & PW article is really nice. It was a wonderful experience and I had a great time.

As per the car after the 1st 5 months of ownership what can I say?

After a couple of hickups due to some wiring issues with the ECU and injectors it is running fine.

I am really enjoying it. The performance is really on a different level. I can honestly say that the car can stay with the likes of 997 GT3 RSs on the track. The driver needs to improve a lot though to take advantage of the car's potential.

Clearly it came out much more hardcore than the initial (remember 28 months ago? I was going to be my daily driver.... ;)) proposition.

Between the aggressive cams, the huge ducting for the massive oilcooler (with no thermostat, even though we are fixing that), the impossible toe settings etc it is a real handful on the awful UK B roads.

But take it to Silverstone, Doninngton or Brands Hatch and it is just a blast!

And this is just the beginning.... I am really happy and proud of driving the 911!

But he made up for it by some nice short acceleration runs, man that thing was like being in the millenium falcon going into litespeed!!!

I was in an Audi R8 the other day...sometimes it's actually better from the right seat...seems faster then it actually is. My first introduction to Porsche cars was in a wild ride in a well set up 73 911S. I'll never forget it!

Great writeup in 911 & PW! I'm sure most of you noted the author... ;)?

Scott,
Did you write it? I haven't seen it, but will try to pick up the magazine.

Thanks, Doug, I'm sure you were typing that with your tongue firmly planted in your cheek, but no, the writer is one of our own, fellow Pelican contributor John Glynn (johndglynn). :D

Matteo, can you summerize how the engine would perform as an ocasional dd? Looking for feedback on idle, starting, general docility around town and on high way. Any issues w/ gasoline?

John did an excellent job with the article, but what stayed with me is the fact that he is a true gentleman.

The day of the photoshoot I was meant to drive 150 miles to get to the location.

Whilst on the highway all of a sudden my car started cutting off. Remember that I have had the car now for just a couple of days.

And now i was stranded on the highway... well to cut a long story short there were a couple of issues with the wiring.

The ICU (Ignition control unit form the 993) was mounted on a very small heat sink and was therefor overheathing.

John made a couple of calls and I was able (after having let the car cool off) to reach Tuthill (a very well known Porsche specialist in the area)....

These guys dropped everything and built a bespoke heat sink plate and provided me with a brand new ICU...

But things were not meant to go smoothly that day.

Back on my way the car started running very rough. I eventually manage to get to the photoshoot location but by the end of the day the car was undrivable.

We would find out later after taking the car to Bob Watson (the Motec guru in the UK) on John's suggestion that the mapping was all over the place and that the connector from the wiring harness to the Motec ECU was faulty, firing only one distributor.

Basically the car was running too rich and I wet all the plugs.

I could not drive home (I was 150 miles away) so John offered me his treasured 1976 3.0 Carrera. The agreement was that he'd pick my car up from Bob Watson's after he had dealt with the mapping issues and we'd swap cars back.

It turned out that the problem was not only the mapping. A couple of injectors were not properly connected and the engine builder had used the cylinder temp sensor to control the cold start cycles.

Needless to say the sensor was showing a very high temp immediately switching th map to a richer one too early, resulting to eventually wet plugs.

So it took a while to diagnose the problem and fix it.

Everything now is fixed and Bob switched the CHT sensor with an engine mounted one and remapped the whole thing.

Still John let me have his beloved orange beauty for 3 weeks, whilst my car was getting fixed.

And I had not met John before that day.

To me that goes a long way to show what kind of man he is... I hope I will be able to pay him back sometimes in the future

my situation is a bit atipical. Unfortunately we were not able to solve all the teething problems with the original engine builder because of the fact that the car was shipped to the UK as soon as it was assembled.

But we had to do quite a bit to make it to my liking.

Basically Timmins built a conservatively tuned (rev limiter at 7,800 and not super aggressive cams) race motor for me. Which would have been great had I raced the car only.

But I was planning on driving the car to work (20 mile commute).

So we encountered some problems. First the plugs were way too hard. Second because of the CHT sensor was chosen to control the cold start maps the car (especially during the cold British winter) would not get onto temps quickly enough and was running way too rich. And the maps themselves were all trimmed apart from the top 3 (90-95-100% throttle at above 6k rpm).

This caused problems with the plugs (wet), the engine cutting off when comingoff the throttle (say coming off a highway ramp onto a stop I had to keep it revving above 2k to prevent it from stalling), and lots of backfiring.

But now (and I must say it was a bit frustrating and also a little expensive) everything is good.

The motor is a monster. It idles perfectly at 1k from stone cold.

It revs quickly (the LWF also helps) and throttle response is immediate.

What has surprised me the most is the torque that it still produces. Around town I can just sit in 4th and occasionally drop into 3rd and it would do it all day.

On the highway I cruise at 90mph at 3k in 6th gear and I really do not need to downshift in any situation.

The problem is that it is just too much fun to drive it "on cams" so I am always in 2nd-3rd (good for 110mph) gear.

So all in all it I just love it.

Shush Teo, or I'll have a line of broken 911s outside the back gate waiting to use my car! LOL

It is wide of the mark to say we had only met that day, I've known you through here for quite a bit longer and was glad to be able to help out. I wouldn't give the car to just anyone, but you are a genuine gentleman and it's the least you deserved given the disappointment you were suffering at the time. Plus it meant I got the Blue Meanie to play with for a few days, so it was 'swings and roundabouts' as we say here in GB; no payback required.

Now though it is all good, the car is a proper gem on the move and it goes like stink. What more can a guy ask for, apart from some heat! EFI on throttle bodies is the way to go on our cars; there is no doubt about it. I look forward to working out my own system along similar lines, though staying 3 litres or maybe coming down a bit.

Scott, thanks for the kind words mate ;)

Great article in 911 & Porsche World. I've been reading that magazine for several years now, it's definitely one of my faves, next to Excellence, of course.

I actually went out and bought the mag today after reading that Teo's car was featured in it. Great write-up John! I can only hope that one day I will be as good a writer as you when it comes to Porsches. :cool:

Keep those pics coming, Matteo! I can't get enough of such a cool car to come out of Charlotte, North Carolina! SmileWavy

Doesn't John get to pick your beast up?! Are you sure he did not have something done to your car just to set this whole situation up!;)

John is a super nice guy. I hope to meet you in "real life" someday mate. SmileWavy

dial 911 12-25-2008 02:51 AM

just spent a good while going through page 1 to 61 and i am just amazed at the transformation. any updates on that car? enjoy the car in good health!

peter_soj 12-25-2008 06:30 AM

dial 911, I just spent a good 2 or 3 hours looking through the pages as well. Amazing transformation, and Matteo, if you read this I was just wondering about the color of the car, is it one of the original option colors or your own custom one?

Thanks, and great car!

shamrockcustoms 12-25-2008 12:10 PM

Mexico Blue I believe and it was a factory color

mpeastend 12-25-2008 08:55 PM

I seem to remember that they couldn't get the powder coat color to exactly match Mexico Blue so it is slightly darker/deeper. They then painted the sheet metal in the same shade as the chassis to match the darker shade of Mex Blue. My Iroc is Mexico Blue & it seems a few shades lighter than Matteo's, appearing almost powder blue. I like Matteo's color, wish my car was a little darker.

Reaper930 12-25-2008 11:17 PM

Correct its a few shades darker due to the chassis powder coat color. I think it turned out perfectly as well. The color pays homage to the cars of the era but the slightly darker color really modernizes it at the same time.

good work on rebirthing ur car!...

Hey Teo,
What are you faster in the 911 or the Ford GT? Do you still have the Ford? Great car as well.
