S550 HPDE Prep - Need advice

I had my dealer change my oil, and make a complete mess in the tray area, and it started and stopped leaking a few times until I took it back and made them clean it up.

Yep. I’ve heard a enough stories about dealership experiences that I try to avoid them if I can.
 
You won’t have torque specs for the GT. The GT350 is unique with that as it sees 150 psi and needs the filter tighter than normal to not blow out the seal. The filter is special. It’s a more robust housing as well.

I appreciate the additional info. It’ll save me from trying to find something that isn’t there.
 
I think I found the source of the oil leak. I cleaned all the oil residue off. Then, I marked the filter and the oil cooler with black dots adjacent to each other. Then I hand tightened the filter again. You can see how much I turned it by the space between the two dots. It was almost a quarter turn. So I’m hoping the leak was just due to me not tightening the filter enough after the oil change.9479DA71-0CED-4826-AE73-618371242C7D.jpeg

I did take a look at the pressure sensor while I was under the car. The area where it connects was completely dry.

Ultimately all of your advice helped and I really appreciate your help.
 
I mentioned earlier that I’m installing brake cooling ducts. I got the driver side done and was able to test it in 4 track sessions this past Friday. They were charity laps so not full speed or full braking. But, there was no significant rubbing on the duct hose so I’m pleased with the installation.

So, today I started installing the ducting on the passenger side and there’s a minor problem. The windshield washer fluid tank is in the way...the duct hose doesn’t fit between the fluid tank and the wheel well liner. At this point, I think my best option is just to remove the tank. I’m attaching a picture so you have an idea what I’m working with. Remember this is 2017 S550 gt. If you have ideas on how best to address this little challenge, I’d love to hear from you.

I have the FTB cooling ducts that used to be routed to the fogs and had the same issue - like suggested above, routing to the lower grill is ideal.

That’s a nice way to do it. I hate the thought of starting over though... I might prefer to just pull out the windshield washer fluid tank and do without that. At least for my track weekend at the end of the month. I’m gonna have to think about this for a day or so.

I appreciate the replies and will post an update when I figure out how I’m going to do it.

I should have said this in my initial response...thanks for posting pictures. That’s very helpful.

It looks like you secured the ducts with black tape. Is that right? If so,has it kept the ducts securely in position?

@gtorpedo, I haven’t been able to find FTB brake cooling ducts on google. Could you please provide a link or website?

Routing to the lower grill area will give your hoses a straight shot to the backing plates and should be a higher pressure area than the fog light location. To secure the ducts to the grill its one fastener on each side and heavy use of racers tape (like an extra HD duct tape) - it is very secure.

Thank you! What you’re saying about the routing makes sense.

I actually had found that kit. I just didn’t think it was the one you used because the kit seems to come with round air inlets that reduce from 4” to 3”, like I’m currently using in my fog light openings. Based in the pictures you shared, I thought you had rectangular air inlets.

I should have clarified. I bought a pair of brake ducts (Allstar ALL42140 Black 5-1/2" x 8" Single Hole Centered Plastic Brake Cooling Duct https://www.amazon.com/dp/B006K8K7TU/ref=cm_sw_r_cp_api_txlNAbT5P5Z4S) and fastened them to the lower grill. Takes a little bit of trimming to the duct and cutting out the honeycombs in the grill but otherwise its the same as the FTB setup.

I actually used the FTBR supplied fog light pieces, heated them with a heat gun, and molded it around the back side of the grills. I then put relief cuts to help get some material to overlap, and put 4 screws through it all (washers and nuts), one on each "side" to secure it. Worked great, and has a cool look from the outside front.

Film at 11? LOL:p
Pictures would be cool if you could snap a couple.
