Owner: Tony Car: Porsche 911SC Year: 1978 Engine: 3.0L Cams: Stock Exhaust: Backdated to tuned headers
The airbox has been cut up to completely remove the CIS metering unit and stock air filter only leaving the bare bones parts required for CIS to EFI converison. An after market air filter, and rubber boot have been used.
Below is a dyno pull for the above setup. Peak Hp at the wheels is 187Hp@6250rpm. With a 15% tranny loss this works out to 220Hp at the engine. This is 40Hp above the stock configuration. Backdated exhaust contributes to about 17Hp, so the EFI conversion has made 23Hp!
