Who can wedge my 488 valves open?

[DW91]

Good afternoon - my first post here and was hoping you could help.

I love the sound of my 488 - I actually think it sounds better than most people give it credit, but only when the valves are open.

Is there anyone (ideally in the north west) that can permanently open the exhaust valves? Or has anyone had this done?

Cheers guys 👍🏻

Get a capristo valve controller.

The days of welding the valves open have been over for some time

Hi , drop the rear under tray 8 bolts , don’t need to Jack car up
Un plug DRS & fog light cables & move to one side . Look up u can see the bypass valves on the side of each exhaust pipes , pull the small blue tubes off , plug the pipes with 4/5mm short machine screws .take the holes in the valves to keep any dirt getting in , Job done then just Put it all back . There is some pics on the Ferrari chat forum just search for them

[DW91]

Thank you - that’s sort of the response I was hoping for, or for somewhere that would do this for me.

I was looking at the valve controllers but they need fitting too I think - and I’d rather just have them open permanently.

I’m not great with a spanner - is it an easy enough job or can I cock it up somewhere? Haha

If you aren’t great with a spanner then it’s probably best to get someone else to do it for you.
Just get your Ferrari garage to fit the capristo remote next time the car is in for service as the undertray will be off during the service anyway.

R&D automotive in Eccles did my 458, think it was a couple of hours labour. Would recommend them.

I did my 430, 360, 458. Took less than 10 mins with a screw driver and two golf tee's. Very easy I'm crap on the spanners and never caused me a problem with any of them. Just asked the same question for my f8. Apparently not so easy.

Hi Does anyone know of a UK supplier for the Capristo valve controller for a 488 ?

Try the official importer, Scuderia

[BarryP]

Forza valve controller is a better option, buy it direct from Steve Bisell in the States who makes them, it will work out much cheaper even with import duty and only takes a few days to arrive.

Forza Componenti valve controller is a better option, buy it direct from Steve Bisell in the States who makes them, it will work out much cheaper even with import duty and only takes a few days to arrive.

Not sure if it fits the 488 (can't see why it wouldn't?), but i've got a brand new one for an F12/FF which I never got round to fitting that's for sale

Also regarding the above comment - i've heard the Forza one can lead to check engine lights so i was told to avoid

[ANOpax]

I'd stick to Capristo (in fact, I did as I have it in my car) as the Forza controller gives you the option of leaving the valves closed all the time which is potentially harmful to the engine. And with Capristo you'll have importer backup in the unlikely event that something should go wrong.

Like many aftermarket parts for Ferraris, the best solution for US owners is a US one and the best for UK owners is a European one. For example, catless headers (manifolds) for the F430 - get Fabspeed in the US, Capristo in Europe.

I have the forza componenti controller and it is excellent. The statement about leaving the valves open or closed all the time harmful to the engine is strange and I'd like to know how you come to that conclusion - there is no evidence for it across any of the ferrari forums.

Leaving them closed all the time is the dangerous one - it can lead to excessive heat build up because the gasses can’t flow as they should. Also increases back pressure a lot

Yes, oft repeated by the competitors of the valve controller systems, no evidence of damage ever having happened.

Not 100% the case you will get an overheat warning from the cat sensors which you would be stupid to ignore and if you did i suspect would end up with damage or at least thats what happens with Lamborghinis.

Having designed exhausts for high performance cars, and done plenty of testing, I can assure you there has been damage done. Why wouldn’t the manufacturer offer the option to keep it closed all the time otherwise?

Wasn’t the request to keep it open all of the time? I don’t believe that any of the controllers give the option to keep them close. In my experience it’s operational, which means valves open or off, which would go back to standard operating.
