Scuderia Owners: Free power upgrade

Any pictures please?

 

It works!

Many thanks.

 

You should probably cap the valves' stems too, so no dirt gets in there. You never know, in the future you may want (or need) to hook the valves back up. A vacuum line cap works well.

 

Did this a couple weeks ago. way cooler sound.

 

Pictures ?

 

Pics would be great. I dare not venture in there without an illustration of what im supposed to do...

 

This work opens the exhaust valve permanent, or am I false ?

 

Yes I have done that to all my cars. 430's it works as well and 360's. Make the car sound much better. Hell I even did it to my Bentley

It can be done on 360 and 430's with removing anything as well. Takes two minutes

 

correct. To me, the scud seems much louder than the F430 once this mod is completed.

 

I did this on my CS and loved the sound. Does it also take away some back pressure so there's a slight power loss down low?

 

Does anyone have pictures on this?

 

Will do it one mine..........thanks Rad.

 

Just did it, sorry no pictures. Remove small triangular mesh screens, one on each side, to get access to hose. I can't tell if there is more power, much louder, best part is the burble on downshifts. Another realization that Ferrari made this car almost perfect in stock form, the new sound is very annoying for everyday driving.

 

But I thought the valves in the exhaust were suppose to hold the pressure in low RPM to improve low end torque. By opening the exhaust system, that would have the opposite effect as you have mentioned above! Are you sure???

 

That was my question as well.

 

yup, some people like it some folks don't. but the reason Ferrari did it is not to appease the milder folks, it is to meet noise regulations.

no, it is strictly for noise regulations.

backpressure to improve torque is somewhat of a myth. in the old days it helped because of non computerized ignition and fuel systems. so as snopes would say, true but outdated. think about it: an engine is an air pump. restricting flow can only hurt performance.

 

When you say its louder, does it give it drone? My dad has a F430 and I'm going to see if he'll do this, but he doesn't like a lot of drone...

 

Hey Rad, would you mind posting some pics for the "not so mechanically inclinde"??

TIA

 

I guess I will try this later this week, I like it loud. If no one's posted pictures by the time I do the mod I'll post some up.

 

Can you tell me how to do it on my CS? And this may be a dumb question, but is it something present on aftermarket exhaust systems as well? I have a Tubi GTC.

 

Correct me if I'm wrong, but isn't this "mod" just causing the exhaust valves to be permanently open? If they were going to open at high rpm anyway, wouldn't you violate noise regulations if you were to shift late? There was something very similar discussed in the 599 section, from what I recall, there was similar mention of power loss because the car was very specifically tuned to operate at peak efficiency with the amount of back pressure present when the valvues were closed at low rpm. Hence any changes in back pressure would only cause a loss of power.

I'm completely mechnically uninclined, so I'm just stating what others have said, but you seem to know what you're talking about so I'd like to hear your opinion on this matter. I'd actually really like to do this mod myself since I like loud exhausts.

 

The CS sounds terrible with the valves permanently open, somewhere between a tractor and a civic with a 5inch exhaust on it. Get someone else to drive your car when you do this and listen from outside, awful. You just pull off the two vacumn hoses you can see when you open the engine cover.
