Mine has all of what Ninemeister has listed bar the intake, infact it was the first car they fitted with the custom ball race turbo, it's had head work and porting etc too. I'll try to post a chart showing it against a 930 with just a 1bar spring but i'm no good on computers so i'm not sure it will come out

What about supercharging?
Isn't the base car for AdamT's YellowBird a narrow-body Carrera???

Spot on Gaz, the Yellowbird is based on the Carrera 3,2
all the best

Adam do you know what exactly the CTR has in common with the 3.2 carrera? Is the suspension different? I've read that the engine the same as the 930 turbo just TT'd is this true? Can anyone guess what the top speed would have been if the turbo-body had been used?
Also...so if you go to town via the ballrace turbo etc, would it be as quick if not quicker than a CTR?
Hi buddy,
The 3,2 carrera was only used as it was a much narrower basis than the Turbo with the wide hips.
The engine is nothing like the engine in a 930 turbo
With a turbo body i would guess the top speed would have decreased by 3 or 4 mph (thats purely guess work on my behalf and not scientific)
Concerning ballrace turbos, it would be interesting for sure, but i doubt it would be anywhere near the CTR
all the best
adam
there goes my best chance of having a car that could possibly perform like a CTR then!
Out of interest why would it not be close? Something to do with the twin turbo's as opposed to one huge one? What size turbos does the CTR use? And what boost pressure?

jbl can't make out anything even from the link! Can you explain what its showing? (apart from the obvious)
It's just a dyno graph showing three back to back runs of my 930 showing a peak of 497bhp and 617nm against a stock 930 running 1bar showing 320bhp for comparrison. 9m/Ninemeister did the work on my car, the list reads similar to what he listed ealier in the thread.
There are on going issues with the WUR (warm up regulator) which still aren't resolved completly, on the whole the car runs fine and has done for the best part of two years, there is nothing better than full EFI at this power level or higher which is where i will be going eventually, but bang for buck the ball race turbo and the other work makes the car a bit of a giant slayer
Sorry, bit of catching up to do:
1. Yes we can organise a live remap for a 3.2 Carrera, a good engine typically makes about 250hp, around 5hrs work on the dyno, cost £500+VAT.
2. 930 turbo fuel system is K-Jetronic, and despite its name has no electronics in sight. As JBL hints, full engine management is definitely the way forward but you then need flywheel, cam, et, at, MAP/BAP & tps sensors, fuel injectors/rails/regulators, injector housings, ecu, wiring loom, and a shed load of time to fit it all and get it working properly, estimate somewhere in the £6000+VAT level.
3. JB I doubt that a silencer will make a lot of difference to your engine, but you have nothing to loose.
4. I think JBL's engine in a narrow body car would not be a lot slower than a Ruf CTR, and I think if you have a look at the area under his power curve it will easily outperform most twin turbo set ups. As mentioned earlier we have just fitted a set of headers to a BTR which shares a similar motronic fuel system (although not the same intake manifold) and it made 460hp at 1.2bar on our dyno against JB's car makes between 475 & 500 at 1.0bar depending on conditions. In my opinion modern ballrace turbos are now far more efficient than two small turbos (although packaging is more difficult - which is probably why the 993/996/997 now use two) and they are available in many trim levels to suit anything up to 1000hp. Our current single turbo dyno record is over 650hp....

Colin, not sure if you've seen these pics but thought you might be interested, had the old girl in for some detailing, it came out quite nice don't you think. Will give you a bell next week about getting her in again, not sure if it's the WUR or something else like a vacuum leak or dodgy AAV but it sometimes runs a bit lumpy and ticks over at different levels, although it was faultless today? Think i'll go for the intake mod and a new back box (more for sound than anything else), and you can fit the larger injector too
