Scuderia exhaust valves, any sense to open all time?

If you go for a long drive, you'll probably find the drone unbearable and you'll also be deaf by the end of it.

 

if u want to go deaf!
get the capristo control switch

 

All it does is give you a nicer sound at start up and cruising through town (below 4k) which I do alot, I hate having it so quiet that it doesnt feel like your driving a Ferrari. I have the Capristo Twin Sound with Remote so I have the best of bot worlds.

 

Fabspeed is currently working on a Valve controller that will have three modes. We are planning to have an Always open, An always Closed (regardless of RPM) and an OEM type function with an adjustable RPM switch.

I do not currently believe that anyone offers such a controller, but it would be all of the positives combined into a package with none of the negatives.

 

Yes it's nice to hear the engine at low RPM. I had my valves unplugged before my S Line exhaust.

I have the Capristo remote and love it. I pretty much drive with valves open all the time unless I get a phone call (and hear it)

 

What about the effects on power/torque? Wouldn't power/torque be lower at low RPMs with the valves open?

 

I've never noticed any real difference. Power isn't really made till after your revs are up and valves open on their own anyways. It's really just for sound I'd say.

Why would you want a mode to have the valves always closed. Wounder what effects to the engine with the valve closed at wot

 

Only reason I can think of is if you go to a track that has noise level restrictions.

 

You also might try the Forza Componenti controller that is advertised in the for sale section here on FChat. Improved functionality compared to Capristro for half the cost.

It depends on RPM and engine load - you can experience that clearly when you rev it in neutral, the valves don't open until way up in the rev range.

There's a good writeup here Ferrari 360 & F430 Exhaust Valve Control Unit | Aldous Voice with a link to another forum where the logic is explained in more detail. It also describes how to build such a remote control unit if you are so inclined!

 

I would prefer the Capristo kit, plug and play!

The one from Steve here on FChat is plug and play. Check his video here.

+1 on the switch. Amazing mod and very inexpensive. Even if you think you will mostly use the loud mode there are many times when you want to quiet the car down. For example of you are coming back late or leaving early or any other reasons you want to avoid setting off car alarms...

 

Yep! Just installed on my '07 F430. Love it. Open valves with the click of a button. Close them and it reverts back to ECU operation.

Are there any systems out there that allow you to run (i) always open, (ii) always closed, and (iii) OEM (i.e., opening only at higher revs/throttle position)?

Edit: Just noticed Evan's post indicating Fabspeed is working on this. Wondering if there are any systems already on the market like this.

 

Never drive always closed! The engine need open valves in higher revs because
the heat have to go out!

If the valves closed, the system get too hot!

And thanks for the vid Alan, looks fine!

But really big box, the Capristo is really small.

Run “Open” all the time (as I do), you will save electricity by not turning the radio on.

 

This logic cannot be faulted

Is the name of the 'other' ferrari forum automatically censored? Let's try: ***********. Why??
