IIRC, with a stock ECU the fans should come on around 221 F.

did he mention that I stayed up till 3am making that rad ducting for his car ;-) and about 4 hours later I would have to be going 160 mph around BIR!!!

it was worth it, his ducting is sweet ;-p

I found that in a heating thread. The running lights were on when I was testing so I could use the illumination of the gauge.

I'm going to hook up the PFC and check the spread. If the Defi and PFC agree, I'll leave it. If they don't, I'll tap lower.

here are some more pics I dug up

Ducting looks good....some pretty heinous overspray though....

what material is it made of?

bump for question. Aluminum I guess? Thickness?

i noticed the oilcooler doesnt have a duct? is it supposed to be like that? or did you take it off to get a better look at the rad ducting?

There is no OEM oil cooler duct for 99 spec bumpers, I think rotary extreme's duct is the only option right now.

Looks like Dibond or Alucabond; basically two thin aluminum skins with a hard plastic core. Very light and stiff. It's the same stuff I made my front splitter from years ago.

very nice, where do you get it from?

There are these which help duct the oil coolers for the 99 spec bumper, that is it covers up the space underneath the coolers.

Yeah, but I never considered those true ducts... lol gotta love Mazda's engineers

it is not solid aluminum, it is a 'sandwich' material, some type of corrogated plastic skinned with thin aluminum skins. Very ridgid but very light. 1/4" thick.

awesome job... there is NO wasted air. direct to the radiator :D

i think i found a proj for this winter...

looks like a nice job
and a nice car also :bigthumb:

digging up an old thread here... but do you happen to have any sketches or measurements that you could pass along so i have some sort of template to start from in creating my own duct like this?

where do you buy that type laminant material from? i can't find any dealers.

I will be selling them shortly, what type of nose do you have? and radiator?

the lower temps could also have to do w/ the fact that he doesnt have any AC. Usually that sits right in front of the rad obstructing it no?

i have a Sanai Works nose on the way, but will not be installed for a while 6-8 months (better things to pay for than paint right now, but couldn't beat the GB price for the kit), so stocker for the time being. I have a Koyo radiator in it that will be staying put.

please add me to your list of seriously interested persons as i have no ducting for the koyo right now... perhaps i'll just resort to some foam on the sides until the new nose goes on?

can you get links to picture of the nose for me?

i posted a picture of one in your thread about the front splitters (which i'm also interested in, but will have defer purcahasing for a while)

in the very next post, FDNewbie pointed out that the lower contour is very similar in appearance to the C-West front bumpers.

Those pics are making me want to remove my ac and do some clean ducting myself... Its a complete pain with the ac rad and lines in there though.

think something can be done like this for a FMIC? i have a HKS Type S FM and a Fluidyne upright Radiator. the front mount sits 1.25+-" above the R1 lip and the radiator sits back 6" and up 1" from the intercooler. i wish this was possible, but i think you might need my car to make something like this work. i would like something that is flexible that can actually sit under the R1 lip maybe 1/4" and sit right behind the intercooler. so it can get more air under the intercooler.
