911SC
Has won 38.4% of 4048 battles

YEAR: 1978-1983
STARS:
From 1978 the SC was the only normally aspirated 911 available. A development of the Carrera 3.0, but the engine developed less power so that it would suit all markets. A Sport option gave front and rear spoilers, 16-inch Fuchs wheels, sports seats and dampers. COMPRESSION RATIO: 8.5:1/8.6:1/9.8:1
MAX POWER: 180/188/204bhp at 5500rpm (US cars remained at 180
MAX TORQUE:
BRAKES: Front: 287mm discs; rear: 295mm discs
WHEELS & TYRES: Front: 15x6J, 185/70VR. Rear: 15x7J, 215/60VR (16inch rims optional).

911 Carrera 2 Speedster (964)
Has won 37.8% of 4025 battles

YEAR: 1993-1994
STARS:
This combined the 964 bodyshell with the hood and windscreen of the Carrera 3.2 Speedster plus RS interior. It is thought that Porsche planned to build around 3000 Speedsters, but only 936 were made, many in bright colours such as yellow or red, with colour-coded wheels. COMPRESSION RATIO: 10.3:1
MAX POWER: 250bhp at 6100rpm
MAX TORQUE: 310Nm at 4800rpm
BRAKES: Front: 298mm discs; rear: 299mm discs
WHEELS & TYRES: Front: 16x6J, 205/55ZR16. Rear: 16x8J, 225/50ZR16 (17-inch rims optional)

911S (C & D series)
Has won 37.4% of 4135 battles

YEAR: 1969-1971
STARS:
An upgrade in engine size from 1991cc to 2195 gave the 911S a useful 10bhp hike in power to 180bhp. Unlike the 911E, though, the S didn’t gain such an improvement in low-down power and torque, so you had to keep the revs up to get the full benefit of the extra horsepower. COMPRESSION RATIO: 9.8:1
MAX POWER: 180bhp at 6500rpm
MAX TORQUE: 199Nm at 5200rpm
BRAKES: Front: 282mm discs; rear: 290mm discs
WHEELS & TYRES: Front & rear: 15x6J, 185HR

CAPACITY:	2195cc		LENGTH:	4163mm		WIDTH:	1610mm
WEIGHT:	1020kg		0-60MPH:	6.6 sec		TOP SPEED:	155mph

911 Carrera 3.0 (I and J series)
Has won 37.1% of 4105 battles

YEAR: 1976-1977
STARS:
Not sold in the US, the Carrera 3.0 was basically the same as the previous Carrera but fitted with a new 2994cc engine which was essentially that from the 911 Turbo. This engine, with minor changes, continued to power the 911 until 1989. COMPRESSION RATIO: 8.5:1
MAX POWER: 200bhp at 6000rpm
MAX TORQUE: 255Nm at 4200rpm
BRAKES: Front: 282mm discs; rear: 290mm discs
WHEELS & TYRES: Rear: 15x7J, 215VR

CAPACITY:	2994cc		LENGTH:	4291mm		WIDTH:	1610mm

911S G, H, I, J series
Has won 34.9% of 4162 battles

YEAR: 1974-1977
STARS:
For 1974 Porsche realigned its model line-up and 911S was no longer the range-topping car but rather a mid-range model comparable to the previous 911E. It had the same body changes as the base model and 911S came as standard with 15-inch ATS ‘cookie cutter’ wheels. COMPRESSION RATIO: 8.5:1
MAX POWER: 175bhp at 5800rpm
MAX TORQUE: 235Nm at 4000rpm
BRAKES: Front: 282mm discs; rear: 290mm discs
WHEELS & TYRES: Front: 15x6J, 185VR. Rear: 15x6J, 185VR
