currently yes... about 300Kg and 100bhp.

Plans are already in progess to gut the car of any redundent weight, and rebuild the engine to 3.4 twin plug/Turbo S cams spec.

That should narrow the gap some what....

300kg sounds like an awful lot to loose. I wonder where it all is? Im guessing an extra 30 on luxury front & rear seats, maybe 10 for aircon compressor etc, 10 for general insulation, maybe 20 on glass rather than perspex. Just made all that up so it's a wild guess... around 70kg there or so. What about the rest?

The 300kg is what I guess the difference is between the CTR and the T2. I will loose about 100-130kg. I've already got rid of 40kg through exhaust and rear spoiler. The rest i'll make up with brute force (bhp)....

I was talking to Adam's dad (Mike) at Vmax about the weight of the Yellowbird. He reckoned it weighed about 1200 kg, although I heard that Yellowbirds weigh under 1100 kg, does anyone know different?

Adam's Yellowbird has carbon front wings and carbon doors which wasn't the norm I believe. It does have carpet though which makes it more luxurious than my car!!

I always thought sub 1100kg too, & perhaps even nearer 1000.

In reality its more like 1200kg, i mean people spout out lightweight claims and bhp claims but they are most of the time over ambitious and grossly inaccurate imho.

The CTR is about as light as you can make a 911 without going extreme racer.

Like said previously we have the CF Doors, Wings and hood. And then absolutely nothing by way of interior equipment, no radio, aircon,(we do have a ciggie lighter though) we dont even have fog lights. Its bloody brill imho.

UV good luck with your conversion, sounds like a great project. And i look forward to comparing the two cars in the next Vmax. If you can though, i would make your car narrower, because the wider fenders seriously affect acceleration at higher speeds.

all the best

You can shed 40kg from a CTR by changing the Ruf wheels for magnesium lightweights.

Don't get me wrong I love the look of the Ruf wheel on all the impact bumper 911s (had them on my 3.2 Carrera convertible), but man are they heavy mother's.

10kg per wheel is next to impossible methinks.

Porsche with the 964 generation RS used magnesium wheels instead of the aluminium ones, and they were able to loose 10kg total.

Granted the CTR wheels certainly arent light, but they are durable

Pah, lardy, I've driven what is acknowledged to be the lighest 911 (factory) built at 789kg & ok more plastic than a Baywatch girl but it wasnt that extreme...

Ha ha no thats a lie it was like being sat in an oil drum with someone beating the out side with a baseball bat! lovely jubbly tho.

Noisy, peaky, nearly 8k rpm of unsilenced howling screamertastic lump= absolutly glorious

Johnny- yours in comparison is a Maybach vs an (original) Mini Cooper S!

You do have to try an early special 911 to see what I mean really, a 911R is similar & around 800KG, ok worth a fecking fortune, but hey only say 4 to 6 993RSs worth

Alex, whose R did you drive? There are several out there that are bitsas (one famous one isn't really a purebred R at all) and I'm just curious, that's all.

Rear 17ins RUF speedline weighs 24lb10oz/11.18kg, although I'm not sure if they're the same as those on the yellowbird.
Sub 1200kg for a 964 is easy; Mines at c. 1185kg with a 50kg cage and I've identified another easy 40kg and the car would only be as sparse as an RS lightweight.
