I have been told several times that the 1995 F355 is the fastest of the F355 series due to the dual airflow system giving it an extra 5-9 bhp. 96-99 models were moved to a single Y linked airflow system (the dual system however was kept for the Challenge series cars). Does anyone know if this is fact or fiction ?

Welcome llenroc.

Ferrari converted the airlow system for the later model 355 because it's easier for maintainance (one flow meter)/balancing the air flow. But it is true that the dual flow system produces a little bit more power. That's why they're still kept for the Challenge Cars.

hey stradale,
I think the major reason for the change in air intake flow meters was because of the change to OBDII in 1996 vs. OBDI in '95 & all Challenge cars. The throttle plates for air intake manifolds were not changed, balancing(maintainence)of the intake throttles via the set screws is the same on all 355s.

llenroc,

Welcome to Ferrari Forum, good info and observation on the ODB changes too.

Boxer,

Good post/topic. I will have to update the Buyer's Guide with this tibit.

So are there two throttle blades and one air flow meter after MY 96 (I've thought it was MY 97)?

Where are the blades mounted on the single system? Is the distance from the blades to the cylinder shorter on the double system resulting in better response as well?

Pardon my ignorance but what are you referring to when you say "blade"?

Sorry. I guess I could/should have written plates instead...
