mplavery Posted January 7, 2010 Share Posted January 7, 2010 Hi ppl Just wondering how many of you have had problems with overheating due to you having a FMIC with stock rad. I have put on a new larger FMIC and though it would be best to get a alloy rad too before it goes back on the road, Just wonderd should i do it a.s.a.p or leave it and out it on my LIST TO DO cheers Quote Link to comment Share on other sites More sharing options...

Ric Posted January 7, 2010 Share Posted January 7, 2010 I think it's bit of a Myth TBH i didnt have a problem with both of my supra's Quote Link to comment Share on other sites More sharing options...
mplavery Posted January 7, 2010 Author Share Posted January 7, 2010 Never been a problem since fitting mine I never had a problem with my last one although it was a little smaller, i do want to change it to an alloy rad anyways at some stage, just thinking weather it should be done a.s.a.p as i have heard of other people having problems Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted January 7, 2010 Share Posted January 7, 2010 Do you have the FMIC ducted? Radiator cooling plate? Quote Link to comment Share on other sites More sharing options...

Branners Posted January 7, 2010 Share Posted January 7, 2010 The FMIC will take cooling air away from the rad. If you run a car hard on a track day you may well find the engine temperature goes up way more than expected. Day to day it shouldnt be a problem though.

tooquicktostop Posted January 7, 2010 Share Posted January 7, 2010 Never had a problem, keep the stock fan set up though if you change the rad, I feel this works best and of course saves money Quote Link to comment Share on other sites More sharing options...
Alex Posted January 7, 2010 Share Posted January 7, 2010 A poor condition rad will be shown up earlier with an FMIC than without...that's all. Any car going for a hard track session should feature full ducting. Quote Link to comment Share on other sites More sharing options...

Any car going for a hard track session should feature full ducting. sorry to slightly hijack hear but could we go into more detail with the ducting as intend to track the car a few times this year. possibly with a few pics Quote Link to comment Share on other sites More sharing options...
InSvain Posted January 7, 2010 Share Posted January 7, 2010 it could be dust and dirt between the fins so try to blow it out with compressed air Quote Link to comment Share on other sites More sharing options...
Nic Posted January 7, 2010 Share Posted January 7, 2010 A poor condition rad will be shown up earlier with an FMIC than without...that's all. Yeah I had problems with the stock rad after fitting an FMIC, but that was in +30° temps, didn't have any problems after fitting the Power Enterprise rad.

Alex Posted January 7, 2010 Share Posted January 7, 2010 (edited) sorry to slightly hijack hear but could we go into more detail with the ducting as intend to track the car a few times this year. possibly with a few pics Air will take the path of least resistance....that's around items like FMIC's and Rad if given a choice. Many installs of FMIC ruin the stock ducting and allow air to spill over it and the Rad via a cut that is made in an air guide in the nose (required to fit the FMIC). The average joe leaves this gap and air can spill around the FMIC and concequently the rad, rendering both less effective. The rad also loses out as air that's already exchanged heat with the FMIC then rushes towards it, so the air that passes through the rad is not as cool as ambient. To sort thing out properly, you need to go all DIY and trap the air entering the nose in such a way as to stop it avoiding the FMIC or the Rad...(above, below and both sides). Toyota ducted the SMIC very well and that's the priciple you should be going for. As for what to duct with, well anything really, but it has to be strong enough to withstand air pressure forces at top speed. B'Have used expanding foam which he cut to shape, this is great cause it fills all the gaps really well, but is probably a pita to get right...Charlie can probably expand ( ) more on that. Other have tried sheets of ali, plasticard, acrylic etc, cut to shape and fixed in place with anything that'll work. Some aftermarket noses fit the FMIC quite well and only leave you the task of ducting between the rad and the FMIC, whci is easier. The Slam Panels that people make are an attempt to stop over the top flow. HTH Edited January 7, 2010 by Alex (see edit history) Quote Link to comment Share on other sites More sharing options...

jevansio Posted January 7, 2010 Share Posted January 7, 2010 (edited) Check out the thread I did on mine (search for ducting in posts by me), fits one of the biggest FMICs to the stock front, & is very easy to make in easy steps.

mplavery Posted January 7, 2010 Author Share Posted January 7, 2010 Great help everyone, thanks Im not doing any track days so i should be fine, it does have a do-luck front bumper which has a larger mouth then stock which will help out a little more, will have a look to see what air ducks i can add to help too Quote Link to comment Share on other sites More sharing options...

Everyone seems to be saying the same thing, i have never had any problems with the cooling of my car so i will leave it as it is. Quote Link to comment Share on other sites More sharing options...
monsween Posted January 7, 2010 Share Posted January 7, 2010 I had the exact same problem as you when i fitted my FMIC. Turned out the rad was knackered. The Rad was more than enough with the airflow it was getting when there wasnt one. But when i added the FMIC it was goosed. New stock rad and it was perfect. EDIT Check the rad cap first, its the cheap option as that could be broke too Quote Link to comment Share on other sites More sharing options...
nigelboyne Posted January 7, 2010 Share Posted January 7, 2010 never had problem but start with checking the coolant strength. Quote Link to comment Share on other sites More sharing options...
