I have made an aluminium undertray between fmic and rad. The oilcooler is mounted just 2inches in front of the rad, positioned in the center. I have filled the gap with bi-plex (pvc based material with Air channels. Light and strong) which we have at work, but simple cardboard would do the trck

Because the oil cooler is so close to the rad, the black magic e-fan does all the work properly!

Ill check for some more pics

 

Want to make an undertray for awhile (OEM one bit worn out)
What thickness aluminiumn did you use.

 

I think it was 1mm.

Do you have stock oilcooler? Because then you have to make the same vents as in the stock undertray, otherwise temps will go up!
Tried this in the first place with stock cooler in stock position With a closed undertray and oil was 15 degrees higher

 

Wait what seriously? Damn why is that? I've been thinking about cutting out the back of my tray, the part after where the radiator meets the tray, in order to provide a place for air to escape, thus more efficiently sucking air through the radiator, but does it matter where the vents are? I thought the most efficient way was to ram air through both the stock oil cooler and radiator?

btw I used .25 gauge sheet metal I believe.



Oh and nice car. Serves as an inspiration to what I'm trying to achieve

 

It all has to do with airflow, low and high pressure areas. Mazda has tested this and made the undertray like that for a reason...

Dont know how it works exactly, i just know that i tried on stock setup with a closed undertray and temps went up.
I think it could work if you relocate the Stock oilcooler, perhaps by trail and error, to find the right flow passage.

 

yeah have stock cooler, thinking about upgrading oil cooler
Cheers for the info

 

wow that hing is so clean, nice car man. keep it up

 

Good looking FC man!

 

wow that is a clean *** FC dude. keep up the good work.

 

thnx for the support guys!

started on my suspension yesterday, the front arms are almost finished!
just need to put on 1 last bushing and get the arms a bit cleaned up.
then its time to take off the rear subframe

 

I love this car and quality care that's gone into it. Well done sir!!

 

I made a custom undertray out of .25 alum. It begins at the back of the front mount intercooler and ends at the front of the Koyo. The oil cooler is kept in the factory location. I sealed it all with soft 1/4'' weather stripping. I run the CorkSport shroud with the factory clutch-fan. That factory fan with proper shroud to blade clearance does some major heat/air scavanging.

My oil temps went down about 10*F while cruising (165*F constant while cruising) and my air temps dropped 10-15* too. NO TRACK temps tested yet since I am in break in still.

Pics below...not the prettiest thing but it is functional. I had NO factory ducting before.

 

Absolutely perfect. I love your car.

 

how did you mod the 350z hood dampers? im interested in this conversion. i saw a video on youtube.com from EVO-R.net showing hood dampers on an FC3S. are they using their 350z dampers you think? they sell them for the 350z on the website but not for the FC, but theres a video of it.

 

sorry for the late reply...
i modified the brackets that were supposed to bolt to the 350Z hood and mounted them onto the hood hinges.
i made an aluminium spacer to extend the dampers so it bolts right to the oem fender boltholes

 

My RX is ready to go back on the road and track! :mrgreen:

this is what happened the last couple of weeks...

taken out the entire rear supsension


found out that my diff was ruined, because there are 12 teeth missing in total


25hours later i had a replacement low-mileage FD3S torsen diff
mounted the diff in my FC housing, replaced the seals and filled her up with redline oil.



refurbed the subframe


SuperNow main camber control links



PDR solid subframe mounts and lower control arm bushings


OEM vs TC-Sportline camber control arm

 

rear suspension reasembled, but due to the tight schedule to get the car running for the first trackday i decided not to paint/powdercoat everything

everything back underneath the car


did some cleaning and polishing under the hood


here they are, side by side, like father and son
`

 

Awesome... looks great

whered you get that alternator relocation? someone said pineapple racing but i couldnt find it

 

made it myself, like many other things

 

very nice! if you made another id totally buy it. you can even put your name on it lol.

 

well, maybe in the future i will replicate it if there are more people interested.
but at least for the next year i wont have the time for it..

 

haa well keep me posted!

 

amazing car too btw!
