Can the Ferrari 348 be made faster ?

no you do not. Add nitrous and fuel through plate on plenum

 

If you figure it out, please post here.

There are plenty of places to get the Bosch connectors and you'd need to figure out a "Y" connector to use the stock dual harness to convert to a single standalone. I've always thought about it, but never hard enough to do anything.

 

I think ECU's like the holley dominator wouldn't even need a Y connector, it has 50 inputs and 36 outputs with ability to add more via CAN bus module. You could wire up and leverage signals from both halves of the engine using that. Biggest issue would be getting a base tune and making sure all of the sensors were configured properly, but once done it could be an easy almost off the shelf upgrade for 348's (same could be done on 2.7 355's for that matter).

 

It would have to connect to both ECU connectors to be easily removable and be able to control all parts of the engine?

 

You'd have to wire up all of the used pins on the two motronic connectors to the ECU, but it supports like 30 analog inputs, 13 digital and can drive up to 12 coils and 24 injectors (coils, injectors and grounds account for around 10 pins on each motronic connector iirc). You would probably also just not pin out duplicate sensors like coolant temp, cam and crank as there's no need to measure them twice - and as a side benefit you'd always be carrying a spare of those. The hard part would be getting all of the sensor values/ranges and then creating a base tune, but once done any other 348 owner could use it, maybe with slight modifications for different years. I think most of the sensor info is out there. In case of the 355 you could easily incorporate the cat temp ecu functionality into it and get rid of those failure prone units. The other benefit is you could monitor everything in real time (on a screen in the car if you wanted), add traction control etc.

 

With enough time ($$$) you could develop launch control, no lift shift… you could have programs for NOS (if you’re nuts)… programs to control aftermarket valved exhausts at certain RPMs, etc. Bob’s your uncle.

A 3200 pound car going 0-60 in 4.0 seconds is going to require close to 450 HP.
Getting 450 HP from 3.4 litres N/A is not going to happen at less than 9,500 RPM peak power.
This is going to require Ti con rods, higher compression pistons, higher flow intake and exhaust, and bigger cams.

Exhausts are 10-15 HP not 150 HP (although some may sound that loud).

The 348 leManns engine made close to 500 HP and had a 100-hour service life.
I suspect you want it both faster and to have a nice long life.

 

This is why I think the best way is to just remove the entire factory loom and start again, its not the first time I've made wiring looms for engines, my friend who is the engine tuner does it for a living so I have excellent resources available.
Its a lot easier than it might sound.
There is a lot that wont even get used in the factory loom, so it can be a lot tidier to start from scratch not to mention more reliable....
I'm look forward to having more consistency and efficiency from the engine to be honest...
When we get to it I'll share the journey.

 

I mean, that's 100 hours at full tilt. I don't know what challenge car engines last, but I'd be surprised if they didn't need a rebuilt after 100 hours running flat out...

 

The point is you don't want this kind of engine life in a street car.

I knew of several F355 Challenge cars that had engine rebuilds every race or 2.

 

Yeah and that engine IS the street car engine. If the 348 LM engine can run 100hours at full tilt, it'd probably live quite a long life on the street where it's not being run flat out the whole time provided it doesn't have insane compression and can idle without diluting the oil and fouling the plugs...

 

and thats why Ferrari most likely decided 7500rpm and 90hp per litre was plenty for a longer engine life....the F119 can most certainly rev higher with more power, but would reduce engine life somewhat....
