    Help please.

    I'm still trying to corral all the remaining parts for my project. Just secured the Challenge steering rack, Fabspeed headers and header/cat blankets. I'm going to reinstall my Hyper-Flow cats but will have both headers and cats ceramic coated first.

    I'm thinking about covering the transmission cooling system over to the Challenge car transmission radiator set up and then eliminating the inline "heat exchanger."

    I'm also thinking about using the Imola Racing Vented Engine Bonnet Window. See it here:

    Engine bonnet windows

    and the Carbon air intake heat shield:

    Heat protection shield

    The biggest headache have been dealing with is getting fixed back seats and racing harnesses. It's really a bit complicated here in the US. Nobody wants to add the shoulder anchor points in the rear firewall. How did you do that? I think I've found someone who will help me get the anchor points located and weld in some mounting support for the threaded harness anchors. The factory race seat fixing kit has mounting points as part of the floor mount. So, here are the biggest issues:

    1. Airbags - keep or deactivate? If deactivate, how? If keep, what do I need to do to "trick" the system so they are active (I'll need to always drive with the harnesses but that's the whole point; right :))

    2. Standard seat belt: Best bet is to remove them, including the retractable gears (or at least tuck them neatly behind the B-pillar and recover so that I don't see all of the holes). If I go that route, I guess I'll need to "trick" the sensor to show the seat belt is buckled, which will keep the airbag light off. As long as I'm wearing the harness, I'm not going to worry about the added protection of a deployed airbag.

    3. Assuming I can work through Nos. 1 and 2, what harnesses should I use: 4 point (with a Anti-submarine feature like the Schroth Profi 2 ASM) or go the full monty and install a 5/6 point system. I'm leaning toward the 4 pt because I'm not "racing" (and it's way more convenient on the street) but . . . Thoughts?

    4. Or the weird option: Try to figure out how to install harnesses and keep the standard retractable seat belts. The problem as I see it is getting a good fit through the lap openings using the standard belts. It's easy on the shoulder strap side but getting the tab into the receptacle using the side opening (rather than over the top of the side) is going to be a real challenge.

    Looking forward to your words of wisdom,

    Rob

    I'm not sure I understand why you'd want harnesses if you're not going to the track?

    For mounting, I bought a harness bar for my 355, I would have something similar made up. Same amount of work to install and easy to remove. You could easily have one made by any place that does roll cages.

    If you do this please do a write up so the rest of us can get an idea as to what is involved. The radiator from Ricambi is about $1200 and a silly $1400 for a metal bracket that could easily be fabricated. The rest would just be oil lines available from any good hose supplier. I assume they connect at the same points on the casing.

    Be careful doing this on a street car, the heat exchanger works both ways in that it warms up the gearbox oil when cold more quickly. Ferrari transmissions are notoriously cranky when cold, so you could have some crunchy/harsh gear shifts on a street car as it will take longer for the trans to warm up.

    The issue for me is that it will be track "focused" not track only. So, I either need to have some kind of "dual" set up where the standard retractable belts are retained or deal with either (1) deactivating the airbags (probably a bad choice) or (2) creating some kind of jumper or mini circuit to trick the airbag activation circuit to see the seat belt as "deployed and connected" so that the airbag system is still functioning.

    If I can get this figured out, I can remove the retractable cam mechanism from the b-pillars and recover them.

    The next step is to choose between the less complicated Schroth Profi ASM 4 pt. Harness (which was designed more for the track "focused" applications) or go the fully Monty with a 5/6 pt. Harness, which sort of seems like one mod too much.

    I promise to do a detailed post of the project. More advice and counsel along the way is greatly appreciated.

    Pete,

    EXCELLENT point on the heat exchanger and cold start. I hadn't really thought about that. In stock form, the trans fluid on the road cars is indeed being warmed up without being driven. Hmmm???

    Interesting point. Esp. since the tranny is an F1. With a 3pedal we can be more careful placing the shifts.

    But.. as we live in the Southeast, for 9 months of the year its hot and keeping down transmission temps is of greater importance IMHO. If my intercooler pops.. this is something I'm definitely going to consider.

    I'll bet we can use a cheaper oil cooler and fab some lines to the tranny. For the intercooler I might just be tempted to use the adaptor Ferrari intended. It doesn't look like the system has a thermostat. I wonder if it can even be mounted beneath the main oil cooler in the right fender or in 3 pedals where the F1 pump is with a temp actuated fan..

    On the CS it looks as though it's mounted above the muffler area on that bracket that is attached to the rear of the tubular sub frame -- but it's difficult to tell from the parts diagram -- would have to look at the WM. Still cannot figure why the heat exchanger is $1200 and the mounting bracket is $1400 -- ah welcome to the world of Ferrari. :)

    I highly doubt you'll overheat the trans fluid unless tracking heavily. If that's the intended use, I'd swap, but for a dual use or mostly street car I think it'd be a waste. Just keep the fluid fresh so the heat exchanger doesn't clog.

    Gotcha. I'd just get the belts that clip in to the rings you install and you can put them in/take them out easily when going to the track (and you can run the full 5/6 point setup and just leave the anti-submarine belt(s) in the car tucked under the seat). If your main concern is 'cohabitation' of the lap belts so to speak, I think you'll be ok if you just take out the buckle portion of the stock belt when going to track. Post some pics of your seat setup and maybe the issue will be more obvious. I personally wouldn't run harnesses on the street and when harnessed in and helmet on at the track, the airbags won't really add much so I wouldn't worry about them - just deal with the airbag light being on at the track and use the regular belts on the road.

    I have gone from streetcars, to dual use track cars, to full caged racecars. Be very careful. Safety systems are very difficult to engineer. You risk making your car less safe thinking you are making it more safe with added track gear. It would be wise to consider full street safety system while ok the street then harness setup, proper seats, helmet Hans for the track. Some would say cage too full containment seat etc or you are fooling yourself. The Ferrari is not a 100hp miata but capable of high speeds and the energy increases at the square of the speed. Airbags have not been shown to be a problem with helmets and better left functional in a streetcar. Good fia rated seats have an expiration date as do harness belts. Note those dates.

    Also six point parachute style is way better than four point. If you can mount six point hybrid scroth that is the best with individual substraps

    I have a couple of additional thoughts.

    1. Transmission Radiator Project. One of the biggest motivations for this upgrade is my concern about increased engine bay temps due to the new Fabspeed headers and reinstalled Hyper-Flow cats. As noted, I'm going to send the headers to Jet-Hot (Jet-Hot Ceramic Coatings). The headers will be ceramic coated (internally and externally) with the Jet Hot Extreme 2500 coating in Titanium color. I will also have the cats coated (external only). As an additional precaution, I'm also using the Capristo header and cat blankets. The challenge transmission radiator allows for several options to physically relocate the core. I'm inclined to use the factory bracket and location because the other options may involving cutting, etc. As such, in order to ensure good air flow, I will install a vented engine bonnet window. I could use the factory challenge car window and gain weight savings in addition to a specific duct to direct air past the transmission radiator but I'm thinking the Imola Racing option gives enhance engine bay cooling. See it here (Engine bonnet windows) as well as the carbon air box heat shields (Heat protection shield).

    2. Transmission Temp at Start-up. While the heat exchanger works both ways (cooling and warm up), my guess is that the relocated radiator will nonetheless draw heat from the engine bay (particularly when the car is not moving), so I'm just going to need to be sensitive to trans oil temps (and will also change over to better trans oil). Andrea Taurino recommends Royal Purple 75 w 90. Any other thoughts?

    3. Dual Belt/Harness setup. My biggest concern is getting a safe lap belt fit using the standard seat belt because the belt needs to be threaded through the side openings not over the top of the seat. It's not an issue on the retractable belt end but I'm not sure I can squeeze the tab through the side opening and into the receiver end. I also don't believe the receiver end can be forced through the side opening and if it can, whether it will be comfortable or just dig into the side of my right hip.

    I may be selling my setup since I bought a challenge car. It's exactly what ur looking for with custom mounting brackets for the seats and a serious harness bar. All very over engineered by a fellow fchatter. Let me know if you want to know more

    Then you have selected the wrong seat for the application. Either find a dual use seat or use the stock seat with stock belts and change the seat when you go to the track or are at the track. It is only 4 hex bolts. Besides if you change seats at the track you could get a safer seat like a containment seat which would be a no go for a streetcar. Your seat is the foundation to any safety system.

    Couple of suggestions, if you are going to track your CS I would change some of the suspension settings (do a search F430GT has good suggestions for camber caster and tires) and corner weight the car - start with normal ride height and look to get a cross of 50% and adjust at the track depending on how the car feels. Properly set up, it is is very easy to drive at the limit and you can even be a (slow) hoodlum with nice controlled drifts...

    My car has the Swain ceramic coated fabspeed headers and sports cats, that works well (regularly get CEL b/c of secondary air system delete) but the engine bay will get hot regardless of coating and blankets especially when driving hard. I have use Jet Hot coating on other cars, it looks great at first but doesn't perform as well as Swain, especially over time. I have put a lot of track miles on my CS all in the texas heat, as long as you are moving the temps are fine even when pushing the car hard, just account for a cool down lap or two for engine and brakes and you should be ok. Open the lid when in the pits to help further with cooling. Again this is a well engineered car and I have driven it in 114 F and it doesn't overheat so you probably are not going to get you a lot from the transmission mods (unless you have a wind tunnel to confirm effectiveness).

    I also have a 4 point harness (a 3" Sabelt FIA rated with welded mounting points) in addition to the normal seatbelt) and partial roll cage be added safety. As this is a Street/track car I didn't didn't go all out on the belt set up though I do wear my HANS when pushing hard or when there are a lot of other cars on the track just is case. The buckles fit fine through the seat back opening and can be stored when driving on the road and lap belt is mounted off the lower seat frame. Everything clears fine and gives a tight snug fit, as the seat angle is pretty steep, I felt a submarine belt was over overkill (again this is track car not race). My race car is a very different set up... BTW, don't mess with airbags it's overkill especially if you plan to drive the car on the road...

    I went with a 2-pt rollbar for my Scuderia. It is 100% reversible, non-intrusive ie doesn't require any drilling or cabin modifications etc. It mounts directly to the oem seat belt mounts on either side of the car.

    I was also fortunate enough to have been able to get unobtainium oem Ferrari 4-pt harnesses, complete with Ferrari shoulder pad sleeves. It was obscenely expensive but our cars deserve nothing but the best =)

    I think the setup really sets off the interior and makes the already special-to-me Scuderia interior just that more special and "track-focused".

    I abandoned the 5-6pt harness route because I still wanted the ease of entry/exit that the 4-pt harness offered. The 4-pt harness is also what eurospec Scuderias are packaged with and I wanted to keep my car as clean and oem+ (as they call it) as I could.

    This has been really helpful!

    I just bought a Factory Fixing Kit from a fellow FChat member. Thanks Ray! If it works the way I think it should work, I'll need to find a second kit to install the passenger seat but at least I won't have to worry about the anchor point locations for the lap and anti-sub belt anchors because they are built into the mount.

    After a lot of back-and-forth, I have decide to use a set of Sparco DTM Carbon seats (which are based upon the EVO II US). I will need to have Courtney Tassie of Specialty Interior Manufacturing, Inc. recover them to match the interior of the car, but I got a wicked deal on them from Speedware Motorsports. Thanks Shaun!

    So . . . leaving aside whether I will run a "dual" system or swap between road and track as some of you have suggested . . . what's the hot ticket for harnesses? I can get the Factory 6 pt. system but it's uber pricey or I can go with a Schroth set up. You're wisdom and guidance is really appreciated.

    I thought it might be worth re-posting a few pictures of the work done to date. As some of you pointed out, harnesses without a roll bar is potentially a big no-no. I have a roll bar but not a full cage. I had wanted the Factory roll bar but that is absolutely not available in North America. I had the guys at GMG Racing build me bar using chromoly based upon the Factory design and then Courtney covered it to match.

    And a couple of pics of the Sparco DTM Carbons from out in the internet. Ignore all of the Porsche RS stuff, these will be re-done Black Leather and Black Alcantara with an embossed Cavallino Rampante in the headrest (just like my Factory Sport Seats - see last picture).

    Keep the comments and thoughts coming. I'm starting to feel like this project might actually get buttoned up so that I can actually spend more time seating in the seats rather than looking for them!
