Car: Porsche 911SC
Exhaust: Backdated to tuned headers
Comments: 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!
