Project complete – for now.

It’s been a long time since posting, mainly due to my laziness than any lack of progress with the car.  The car is now road going and it’s probably got around 1300kms on the motor.  Here are some pics with a bit of a rundown.

Believe it or not but it sounds better than it looks.

Ready to drive

Another close up

When I first collected the car with motor installed I was a bit nevous.  It was smokey, hard to start, felt a bit flat and certainly running very rich.  There were lots of issues with it sneezing out the carbs so larger idle jets were installed (hence the richness).

It was left in that state of tune while it was sealing itself during run in.  Progressively the smokiness reduced but the other symptoms were there.  When I hit 1000km’s it was straight back to the mechanic for it’s service.  New oil and all other adjustments made and it certainly was running better.  The original idle jets were reinstalled. The decision was then made to set it up on the dyno and so I booked in with Melbourne Performance Centre.

I explained to them the flat spot around 2500, the popping throughout various points in the rev range and what I thought was a lazy acceleration up until about 4000.

The results were significant.  Sneezing is virtually gone (always a compromise but I opted for the odd sneeze at around 1200 in favour for a better mixture higher in the rev range.  I now have about double the power around 1500 rpm which explains the sluggish starts I was experiencing.  Top end power is about 17KW more at the wheels and really gets going about 4200.  Peak power at about 6200.  There is loads of torque and the curve is quite flat.  the result is a very strong motor that pulls early in the gear.  It revs very freely and before I know it it is ready for the change up.

On the dyno the power numbers seemed a touch lower than expected  but torque was 384Nm at the wheels. Needless to say I am very happy with it.  Phil and Darren at Auto Coupe have done a great job putting it together.

All focus on the engine but the 915 shifts nicely.  With the Rennshift fitted it’s a positive shift and might swing any 915 doubter into a fan.

Enough for now.  I plan to do a proper photo shoot of the car – inside and out.  I’ll also follow this up with a series of before and after pics.

Thanks for reading

    Fantastic work! What a neat machine! You must be glad the project is over so you can get out and enjoy it now. Hope you keep the blog going to show us how you use it. You interested in another Porsche project yet? – Cheers, Al. (tripleblack911.com)

    Thanks All. I’ve still got lots more I want to ad to this blog. I want to do some more pics, better before and after comparisons and also some video. I’m waiting for this hot weather to go away so I can have some more use out of the car.

    Who did your plating? Thanks!

      I sent some parts to Auto Coupe for refurb. They are always sending items off for plating so I gave it all to them. I believe it goes to a plater in the Preston area. There are lots of platers around. If you try someone new then have a look at the work first to make sure the colouring is what you want. I know Phil at Auto Coupe would point you in the right direction.

    Love it. Inspirational. I am looking for my 2nd 911 at the moment, similarly to you I sold my first, which I hadn’t. Was this a uk import? Would love to have a chat if possible.

      Hi Rohan.

      Yes it was an import. I was after a Pewter Metallic or Zinc Metallic and after waiting for a local car in that colour I became impatient. In the end buying the car I did gave me the freedom to start tinkering and ultimately led to the restoration.

    great looking car… nicely written blog… did I miss the final HP output result?

      Hi Mike. No, I haven’t posted that yet. I had it tuned by ‘feel’ first but took it to Melbourne Performance Centre for a dyno run. To be honest I was initially disappointed with the HP numbers but slightly comforted by the big torque increase. If you go with the ‘15%’ drivetrain loss then the HP at around 6000rpm was 235 (up from 204). Torque was up from 267NM to 450NM (same 15% calculation). It’s the torque that made a massive difference to the engine, plus very drivable on the street. I remember reading the dyno sheet thinking WTF – I expected 265-285 HP. I was quickly appeased once I got back in the car and drove off. The tyres spin into second gear if you want, not that I do that with my 915 gearbox!

  1. No trackbacks yet.
