I was at the local speed shop today discussing EFI. Because most of us run the same dyno and the owner was kind enough to allow me a look at his 3.2 dyno numbers, I had Alex run a comparison from the computer logs. The A/F ratios were also very comparable fwiw..
The Varioram/Motec 3.2 in BLUE
"911 with US 3.2L, 9.5:1 , stock longblock that has been balanced and fitted with adapted 993 Varioram, MAF. K&N, Magnecore, 951 injectors, SSI, Sport muffler - all controlled by MoTec CD and Fuel management and mated to a early mag 7:31 915 box. I had the 993 Varioram adapted to my stock longblock 3.2L (now sadly history, due to a recent rod bearing failure after 200 track hours).... We did gain 20 hp and 30 ft lb of torque at 3500 rpm. Varioram starts to help the torque curve as low as 2500 rpm, then fills out that curve to about 5000 rpm. At 5900 the resonance flap acts to extend the HP another 500 rpm to about 6500. It is an amazing piece of technology that actually works."
CIS 3.4 in RED
3.2 crank, Puater rods and bolts, Mahle 98 P&Cs @ 9.8 for a 3.364l, SFL Piston skirts, Ceramic coat on the Pistons, EBS valve spring, TI retainers, APR case studs, New injectors, new exhaust valves (which is why I tore the engine down), boat tail the crank cases and half moon the cylinders, Bored throttle body
match and polish the intakes, 20/21 webcams, SSI, sport muffler
light flywheel.
It shocked me! Motec and CIS comaprable? I would have never believed it.
