True. I got mine which is also the basic unit, ON and OFF. No time to fiddle with the valve opening when driving the 430....just too busy flicking the paddles.
I just wanted to share a couple of interesting pictures I received from Antonio Capristo: - Installation of the remote control unit on the right hand side using the existing tail light screws - A F430 transformed into Scuderia using the new Capristo exhaust line for Scuderia. You can see very well the nice work of header and cats isolation using the heat covers. It's also interesting to see the heat shield bowls which are protecting the exhaust valves. Also in term of heat control, the Capristo's mufflers are heat insulated inside several times and have side coolings grills which pushes out the interior heat. Compared to the stock exhaust, the heat in the engine bay should be considerably reduced. I'm certainly paranoid about excessive heat but I consider this as being the number one priority in an exhaust upgrade Stef Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
The catalyst insulation looks interesting. Is it a 200 cell sports cat? and - of course - have you got any price indication for this heat shield? //A.
Stef, Thanks for the pictures on the Capristo remote controller. Could you explain a little more on the Capristo remote controller programming? I assume that disconnecting the factory wires from the stock vacuum controller and connecting those wires to the new Capristo Controller will allow: 1. Valves open at all time, all RPM range 2. Valves closed at all time, all RPM range (what would solve my sound restriction problem at certain racetracks) I read somewhere there was a Capristo ECU that allowed (1) and (2) above, plus some custom ones based on engine load or voltage coming from the stock ECU valve controller.
WOW! Thats a nice conversion into a pseudo-Scud. Very nice! Just need CF intake and plenum covers to finish it all up. Love to see more pictures of the project though...please?
Hi, I try to answer the question, this remote are very easy to install, it will be only as a bridge between the original and the electronic solenoid valve on the valve plug that is on it. then the black cable connected (ground) and it's ready. there are vehicles where the exhaust valves work the other way (for example 355, 550 Maranello), but there is a small switch to set the valve type. when you click on a button: press then our remote control and is disabled as production configuration, will automatically open (it must be so when the exhaust valve to stay up, you risk that the engine has too much back pressure) when you click on button 2: then go open the exhaust valves, and remain open until you press again on the button 1. should not work so, then the small slide switch is pushed on the wrong side, push on the other side then it works. need not be programmed, and fits on any Ferrari. it needs no extra power, there's a black wire, this need only be connected to the frame (ground) information about the Scuderia exhaust can be found at this link.

Yes Anders, it's a 200 cell cat but with a much larger diameter then you uselly find on the market (see other thread which has been discussed about this topic: http://www.ferrarichat.com/forum/showthread.php?t=294704) I don't know the price of the specific cat heat shield. Maybe you can ask directly to Antonio? Cheers, Stef
Hi Rad, As Antonio Capristo explained (who's making great efforts to write in English, thanks so much Antonio!), the Capristo control unit acts as a bridge between the ME7 and the solenoids. With the first button of the remote, the Capristo control unit leaves the ME7 managing the opening/closing of the solenoid valves. What it means is that the exhaust valves are NOT forced closed which would have a dramatic impact on the engine! Position one means simply that your exhaust valves will be managed as stock and that the control unit is bypassed. If the control unit should fail, you will always be in this mode. With the second button of the remote, the Capristo unit takes over the control of the exhaust valves leaving them open whatever the ME7 decides. There is indeed another version of the Capristo remote control unit which is the programmable version. This unit has a backpressure sensor and depending on the mesured backpressure, you programm the unit to open the exhaust valves or not. http://www.capristoexhaust.us/Programmable-remote-control-p/pr%20re.htm for the details. Cheers, Stef
Ok I am convinced. One manufactor of headers says there is no need for heat insulation - the other manufactor develops an extreme heatresistant glove that cover the total manifold. Extreme heatresistant and extreme expensive. Didn´t think of the petrol tanks before, but they are realy close to manifold. Since I got the money I will go the Capristo way. Both manifold / insulation and now also the big body 200cell cats - also with insulation. And I will also heatinsulate the tanks a bit extra. Placed my order today and have of course already forced myself to forget the price. My Capristo headers are now on and tomorrow I will fire up and listen. These manifold are realy a pain to mount and the only complain of these headers is that on some screws there is no space to fit a tool to tighten them. The welding edge at the tubing should have been trimmed at bit. Noticed this when the jobb was half done. Grinded the tool instead and used M8 with 12mm hex head. Grind before you have them into the engine compartment. Standard manifold - piece of cake. Fabspeed - double the time. Capristo - tripple the time. //A
Thanks Anders for your interesting feedback about the headers installation. Very well done! I didn't expect it would have been so difficult to install them. Did you get some advice from Capristo on how to install them and which tools to use? Maybe can you give them your feedback so that they can improve their product? I agree the heatresistant gloves are expensive but isn't 2500$ worth protecting your car efficiently? Headers are so so close to the fuel tanks that I wouldn't fool with this. I just can't imagine the F430 running with the other aftermarket headers without any heat protection or insultation. Looks like suicidal to me...but as I wrote before, I'm maybe too paranoid about overheating the engine bay I suppose you must be very impatient to fire up the engine after all the important modifications you made Stef
Of course it is worth it. Now when you see it - I don´t understand how someone can say insulation is not needed? I insulated my Fabspeed manifolds anyway with the ordinary heat insulation band - but this insulation is next to nothing compared with the Capristo one. Will try to take some photos of tools and where to grind. Will be no fireing up today. Ruined my back on a ice cold garage floor, trying to tighten those awful manifold screws. Since everything else is in place - I will use the std catalyst first. Then cool down and re-tighten the bolts again - and by that time I think I will have the Capristo wide body catalyst and their new insulation delivered. So I will swap and re-tighten and then my exhaust, (expensive) adventure will be over once and for all. I hope. Stef - No I don´t like the way Capristo fixed the remot controll unit to the rear lamp screw. I think it is wrong to just tighten it in one screw - in one flench - it will probably vibrate and braek. I will find a better solution and come back. I hope. Ahh - this day is not so bad afterall. Got an invitaion from a friend - going to Maranello the 10th of April. //A
Here are somer photos showing how close the manifold is to the petrol tank. / You need hands like snakes / Valve location left side. Doubble side tape and string. / Welding edge that should have been trimed. //Anders Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Thanks very much Anders for your pictures. I agree about the remote control unit, one screw may vibrate it too much. Thanks for the tip on fixing it on the vacuum tank. Grace to your pictures, I can now see how difficult it is to screw the nuts there on the headers. You must have been spending a lot of time on them to get it right. Now I see the headers on your engine, I find them HUGE compared to stock! But it's a art of work, really. Take good care of yourself now, you deserve some good rest Stef
Now it is done. Made some new tools to be able to tighten the manifold. Had to lay on the engine - using a mirror and all the tools I could think of - to get to some nuts. Took 3 more hours just to tighten. And I have a complete workshop to suport this job. Had the car warmed up and will retighten a last time tomorrow night - and put the insulation gloves on. Had the engine running for about 20 min. and without insulation at all the manifolds transmit a lot of heat. Have an IR temp reader, but forgot to measure the temp at the tank. Could realy be interesting to see the differens between non insulation and the Capristo one. This week I will have the wide body catalyst with the expensive insulation from Capristo. Will just take 2 hours to change and then I am ready to put the underbody panels back. Service is done. Next winter project will be to change the door speakers and to do something about the springs and Bump Steer. Then Spring is here. //Anders
Someone wanted me to show the tools needed to fit the Capristo headers. Here they are. Some are bent or grinded to suit. Here is also a picture how to handle with the insulation. I fixed som copper wires in the strings - starting from above, pushing the wires through first - then go under the car again and pull in the wire. At last you can snapp the heatprotection together and you are done. If you don´t use my method you will probably find yourself fidling with this insulation next weekend also. It is tight. Realy tight. //Anders Image Unavailable, Please Login Image Unavailable, Please Login
Waaaw, very impressive! This is definitely not a DIY job. I'll leave it to Capristo to install them on my car Thanks for sharing Anders.
Haha - StefVan - now I only have the muffler left to insulate. Shall we ask Elain Romero to deliver a blanket of this marvelouse material that we can sweep around the muffler? - Or is this to go too far? You can´t get a cooler engine compartment than that. //Anders
I think there is no need to insulate also the muffler except if your silenced muffler is retaining a lot of heat... BTW, I'm not even sure the heatglove would fit arount the Capristo muffler. Also, their mufflers have side vents to expulse the heat which wouldn't be compatible with heat covers Related to your headers installation, I'm really wondering how Capristo does this and how because I will go there next spring to get the installation done by them.
Nop - no side vents on mine. Know what you mean, but my round vents are all solid. Would be nice to see some drawings of the different mufflers. //A.
Please measure your manifold temperatures with and with out the manifold blanket insulation and post the temps here.
Chris, I don't think Anders is gonna remove his heat gloves after all the hard time he had to get them on . But it would be interesting to have a temp reading with the heat insulation in place so that it can be compared with the stock headers.
