Just FYI guys, I just spoke to Chris over at RP (www.rx7.com) and he has five 1999 undertrays in stock at $130 each. They don't have the upper second layer that the 93-95 pans have so there is clearance for a front mount setup. I know these can be tough to find (there is a long waiting list at mazdacomp, which sells them for ~$100) so wanted to let the forum know. Running without an undertray leads to high temps, especially at highway speeds, so an undertray is not a part to drive around without

Rich,

what is the best way to nab one, give them a call right now? I dont' see them on their site. EDIT: ****, I just saw they were closed.

I have a Greddy three row and never had a clearance issue with my stock under tray. Am I missing something here? Whats the problem?

Perhaps it has to do with the orientation of the a/c condensor? I have a SMIC so never had any problems.

Actually, I was looking under the car yesterday and noticed my 3-row does not drop below the tie hooks in the front. I was thinking a normal would clear but Ray said after the turbo install that it probably wouldn't (he said it out of nowhere, so this whole time I have been wondering what to do). Now with your post I'm thinking I may not need the 99 spec and the normal would work.

There is some misinformation here temps, with a FMIC will not go up with the tray off at least not with the Radiator in the vertical position and AC condenser in the horizontal position.

It will open your belly to damage like what recently happened to Rynberg.

In my setup I don't think the AC would work with tray on and I know my temps would go up.

Not really sure what you are saying here. I have driven an FD (with greddy 2 row fmic setup) without an undertray for a 150 mile highway trip and had problems with the coolant temps creeping up to 105 degrees celcius. Put a hacked-up 93 undertray on the car, and on the same day, making the reverse trip, temps stayed at 85 degrees celcius.

whoa, I need to get my **** on then. Also, I realized a couple weeks ago my 4-blade fan is busted I need to do soe work on the car, but living in a new townhome isn't very conducive to working on the car.

105 while moving at highway speed? In the dead of summer in FL w/AC I only see under 100C at highway speed. The under tray kills air flow with a FMIC.

Also with the stock setup I would see around 103C under similar conditions with the tray. Around 95F ambient in the afternoon.

Are you running the stock radiator in the stock position?

When I had my blk FD with greddy 2 row FMIC with Fluidyne verticle rad, it still hit 94-96 on the interstate without the fans on. I had 99 front with the 99 underbelly. It might of help a little, but I think best is to run your fans. I didn't have datalogit and never change the fan temps.

It was a friend's car. He had a custom made large capacity radiator, not sure if it was in the stock position or not.

It may be Rich. I ran the ac condensor behind the radiator. I dont know if the stock undertray is supposed to rub but mine did not.

Herblenny

Hmm.. I would like to see a pic of that if you have it. Was your radiator verticle?

Also, 99 spec undertray comes with big foam thing that you could peel it off and relocate so that it will go under your verticle Rad location. That would help seal off so that the air will have to go thru the rad.

It actually pulled the engine and ac along with Phil or I would have been happy to snap a photo.
I run the mazdacomp radiator in the stock location and mounted the ac behind it on purpose but it was pointless since the ac was never cold.

You know it takes like 10 minutes with a dremel to remove the upper tray from a 93-95 underpan right? Costs nothing.

GoodfellaFD3S

Yeah, as I understand it that is the popular 'mod' with the fmics. I was posting this as an fyi for people without undertrays altogether. the 99 one is cheaper than the 93-95 one.

Just got one. They were very nice on the phone. Came to $146 shipped.
