355 engine w/360 parts??

Maybe they are running MAP instead??

 

I think there may be a way out there. It should breath easier too

 

ASk No Doubt. It could be that since racing street drivebility and emmissions is not an issue. Therfore, they can Alfa-N? Throttle position and RPM to sence load and they map the ECU based on that.

 

I think the goal would be to use the existing ECU .

 

Not my expertise either, but I've been doing some research on this so I can put open stacks on my 355 tbs. There's a guy who builds a box that will interpret the signal from a map so that your motronic reads it as a maf. The maps I've tested give voltage readouts backwards and in a narrower range than the maf on my motor. See my thread "355 throttle bodies on a 348" for the reference. IIRC, he gets about $400 for the box.

 

Hey Plugzit, Gothspeed ,

Are'nt those tubes Helmhotz trompettes?

 

That's what Imagonnado. IMO, the more controls and sensors you have, the finer the tuning, the greater the horsepower, but the mafs limit the possibilities. What I'm really going for tho is the look of old Hilborn injectors sticking out of the hood! (I'm that old too).

 

Yes, it looks like they were made to produce the fabled Conical Helmholtz effect, said to create a tornadic effect. By taking the outside airflow from the tornado, a high pressure ram effect is created thus obviating the need for turbo- or supercharging. The problem has always been sustaining stoichiometry throughout the curve. A moving chicane solution has been sought for eons using everything from transducers to gerbils. A change to Motronic 5.8 would seem to help, but even decimals on Motronic systems create a new problem that can only be solved by arithmetic. Your input would be apprecaited.

 

No. The opposite actually.

 

What's the opposite of trompette?

 

You got it exactly!

 

95 F355 Euro Spyders are the only Ferrari I know of that have helmholtz resonance involved in the intake.

The stuff going on between the 360 intakes is not quite the same.

Sounds like the ticket!! Are you going to pull the trigger??

Absolutely!! That way I can just put air cleaners at the inlets

Plugzit!! You have gone mad!! It may be stemming from the aproximal overexposure of the 355 TB's to your cerebellum causing a cyclical disruption to your central algorithm processing intermediary whereby your modus operandi has been markedly amended to its exitant constitution

So in summation you are screwed up and in severe need of an F355 as a counteractant !!!

 

Sorry if I scared you. Sometimes I have short periods of lucidity to screw up an otherwise gloriously insane day.

 

LOL

 

Air flow meters can be removed with an ECU flash..

you can then remove the filters and sensors which restrict flow so much.

Mixture map is then dependant on pre set throttle position based programming and lambda readings.

Here's an opened 360C air flow meter... note.. straight through.. no air flow sensor in the way, and the sensor terminals are simply folded flat out the way (looks like std from the outside).. You could always just fit a straight pipe.. but unless you have rigid engine mounts (360 Michelotto), you need the flexible tubes.

also, here is a modified 360 Inlet manifold..
