430 What is the torque value for the bolts on crash plate at the back of the gearbox?

    My fabspeed exhaust bracket rubs against the diffuser (both stock and new) and I can’t really adjust it away without my Kline exhaust hitting the bumper (the Kline is a work of art but they have a single piece for the bottom which doesn’t allow much alignment adjustment).

    Plan A is to have my mechanic take a look and possibly trim the bracket a little. It’s busy season so not sure when he can get me in since he will need one of his lifts.

    Plan B is to remove the bracket myself as I already marked where it needs some trimming then bring it over to a machine shop who would have a band saw to cut it and then reinstall. I would go to town with an angle grinder myself, but it might discolor the stainless steel on the bracket too much. A machine shop would have experience on how not to overheat the stainless.

    If I go plan B, i found the torque specs for the bracket itself and the U bolt, but can’t find the specs on the black crash protector. Pretty sure it has specific torque specs because it is marked that it was torqued with a pen. See pic.

    Anyone know the specs for the bolts on the crash protector?

    Btw in the pics you can see the white fiberglass to see how far it wore a groove in the diffuser, so I think the bracket needs to be trimmed a little more to give extra clearance which is what the sharpie line is for.

    24 - 30 nm - that is for a Scud not sure if the same

    The WSM that I have for the 430 does not have it .. the scud wsm has it on d1.03

    Thanks. I would assume the value is the same for the 430.

    Given the range and similar gear box i would say it is a pretty safe assumption

    Corey, it looks like that would be real easy to trim off with a small angle grinder, with it still on the car. No need to remove it.
    Harbor Freight has cheap ones. I think they are called 4” angle grinders.

    Its only a tiny bit to take off, either use an angle grinder with a disc for stainless and dont press too hard or use an engineers file and a vice.

    I would recommend giving Fabspeed a ring and see what they suggest. I'd think they should be ok doing it for you since their design added too much material creating a 'wing', unlike OEM (pic attached). They're a nicer 1 hour drive out to PA from where you are.

    I've also attached the Torques table from the manual. I was trying to find that same torque spec, it doesn't list specifically, I went with 24 Nm.

    I was going to go to Fabspeed and see what they could do with the bracket and I decided not to bug my mechanic with this as he has better things to work on even though he did offer to just trim it with a plasma torch for me. So I wound up taking the bracket off myself and bringing it to a local machine shop and they trimmed the bracket. Figured this way I don't have to drive the car around half assembled and I do need to get comfortable doing stuff on my Ferrari myself. If it was my GT3 I wouldn’t hesitate to grab a wrench and fix something.

    So installed everything, and torqued it up to spec using my brand new Harbor Freight digital adapter (I have a good 1/2 snap on torque wrench but it's enormous and I only use it for lugs).

    The big question... I'll drive it around tomorrow a little to make sure nothing rattles before I put on my diffuser, but should I re-torque things after driving or once it's torqued it should be ok?

    Thanks,
    Cheers,
    Corey

    Glad you're all set!

    I will leave the answer to that to the more experienced folks

    I have done retorquing but have never found that anything moved

    You only need to torque it once.
    If you are installing new wheels, especially aluminum ones, they need retorquing after 100 miles.

    Is your new diffuser shaped differently? I’m assuming your stock diffuser didn’t hit the exhaust bracket. Or did you install the new diffuser and new exhaust bracket at the same time?

    Stock did hit the bracket also, only noticed it when I installed the new diffuser and was on the ground looking though the mesh. It seems there is a groove worn into the original diffuser which is the white "fiberglass" dust on the bracket.

    I only drove about 100 miles since the bracket was installed with my new Kline exhaust. This is really an issue with the Kline since the entire bottom of the exhaust is a single piece (X-Pipe to all four tips) so there isn't a whole lot of adjustment according to my mechanic. Most exhausts separate the left and right side so they can be adjusted individually with more "play". The Kline is a work of art, but that is one downside. I also think the stock brackets wouldn't not have hit. The Fabspeed brackets are flowing in design so they are a bit larger than stock.

    If I read Corey's post right, Fabspeed bracket wore into the stock diffuser, he didn't want the same to happen to the new CF diffuser

    You said

    "I also think the stock brackets wouldn't not have hit."

    I'm about to install my Kline with stock brackets

    Presume you meant stock brackets would not have hit?

    Thank you

    Yes. The stock brackets don't bow our as far as the Fabspeed. When I looked at my cars service records while I was putting them into a book, I noticed two brackets replaced at different times under warranty so I figured I'd just replace them pro-actively with the Fabspeed ones.

    Here is a pic of the slightly shaved left bracket installed.

    I could have filed it down or cut it with an angle grinder. I’m kind of a perfectionist/OCD so it had to be done cleanly on the right machine where it didn’t discolor the stainless from the heat.

    I am a bit handy with a file after 40 plus years on the hand tools. Filed a few shaft keys out of round bar before now, ships normally only have a lathe so you need to be adaptable

    I'm pretty handy too, but for some reason I'm not comfortable doing much mechanical work yet on my Ferrari. Strangely, I have no issues with working on million dollar museum artifact restorations on a daily basis so it's not value based. I think it's something I just need to learn to be comfortable with. The pandemic doesn't help because I feel guilty about working on my cars instead of finding something to do with my family that's allowed. Before the pandemic lockdowns, I nice trip to London, Paris or Prague would get me months of time working on my Porsche or some other project without a guilt trip from the family ;)

    Cheers,
    Corey

    Went to put on the diffuser and while it didn’t hit it was only a few MM clearance on engine startup. If I ever had an engine mount go it would hit and crack the carbon fiber. So off came the bracket and I took a little bit off with an angle grinder and a stainless steel flap wheel. I took my time so I wouldn’t overheat the metal and then cleaned it up with a file. I’m still glad I had it initially done by the machine shop as it made me more comfortable just taking a little more off with the
    Angle grinder.

    Anyway here are pics of the bracket installed again and the diffuser. I hope to take some better pics of the diffuser tomorrow with the car out of the garage in the sunlight. Just had too many things to do today I didn’t get more than a drive around the block to check everything.

    Yep, Kline Valvetronic exhaust with the Inconel button in my accessory power socket to control the valves. Actually the tips need to be adjusted, the left side is about 5mm higher than the right. I got instructions last week from Kline on how to do make additional adjustments but want to order spare clamps for the exhaust to cats because there is a chance when I loosen them up I might need new ones. Apparently there is special procedure to get an extra 20mm of adjustment that is different than other exhausts because both sides of the tips are welded to the X-Pipe and exhaust input.

    Cheers,
    Corey
