GetawayDriver Posted September 7, 2006 Share Posted September 7, 2006 hello, Car has started to overheat when been driven hard after installing FMIC. car is UK spec, running 1.1bar ish on stock turbos, fuel, hks intake. Rad is almost new so in good condition, good quality coolant, checked thermostat, fan etc, just seems to be air flow issue. i don't currenly have a engine undertray on and i have a do-luck style front end (which seals very well on the front of the intercooler). anyone got any reccomendations? do the radiator slam pannels make that much of a difference? cheers j Link to comment Share on other sites More sharing options...
Thorin Posted September 7, 2006 Share Posted September 7, 2006 If the radiator is in good nick it's probably an airflow issue, you could try and make up some proper ducting, undertray and slam panel would probably help. I'd do that anyway whether I was getting a fluidyne or not. Now why don't you like dogs feet? Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 7, 2006 Share Posted September 7, 2006 did you replace the fan you removed?? as Thorin said....air will be exiting right underneath if there is no undertray as it will take the easiest way out....so will more than likely just blast right out under the car giving your rad no cooling effect at all.....you need to seal as best you can around the bumper and around the outside so no air can escape once through the core Link to comment Share on other sites More sharing options...
GetawayDriver Posted September 7, 2006 Author Share Posted September 7, 2006 i think i need some big sheets of ally, i feel a custom undertray coming on. dogs feet? - odd i know, but they're quite pointy and they don't look comfortable to walk on. they look like they might break quite easily and they make a silly noise.

GetawayDriver Posted September 7, 2006 Author Share Posted September 7, 2006 i haven't removed any fans. can you remove the stock fan and have twin electrics ones? Link to comment Share on other sites More sharing options...
Thorin Posted September 7, 2006 Share Posted September 7, 2006 i haven't removed any fans. can you remove the stock fan and have twin electrics ones? You could, but they would probably be worse than the stock viscous unit. Link to comment Share on other sites More sharing options...
SEDGE Posted September 7, 2006 Share Posted September 7, 2006 Yeah i had a similar problem..good ducting usually sorts it out. Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 7, 2006 Share Posted September 7, 2006 to fit the FMIC you must have removed the stock electric fan, the air con cooler, sheilded by the metal gauze, not the viscous fan attached to your pulleys?? it comes on when your air con is on?

GetawayDriver Posted September 7, 2006 Author Share Posted September 7, 2006 def didn't remove any fans or metal gauze, mine is UK spec. mine only has one fan, the viscous one. maybe this is part of the problem?! Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 7, 2006 Share Posted September 7, 2006 there should be a fan on the air con heat exchanger, has anyone got a pic?? I replaced mine with a slimline spal jobbie, go to a breakers yard and see if you can pick up a bargain....has to be really slim though 1.5inch max Link to comment Share on other sites More sharing options...
kosmic Posted September 7, 2006 Share Posted September 7, 2006 I managed to fit my 2 row front mount intercooler just right so that i didnt have to trimthe Do-Luck at all and managed to keep the stock air-con fan & cooling coil. All i had to move was the air con filler nozzle and reservoir tank. Il post up pics tonight when i go and see the car Link to comment Share on other sites More sharing options...
Kranz Posted September 7, 2006 Share Posted September 7, 2006 I didn't have to move anything when I fitted my FMIC... Lucky??? Link to comment Share on other sites More sharing options...
Ian C Posted September 7, 2006 Share Posted September 7, 2006 I think that fan is autobox only Undertrays, as big a pain in the ass as they are, are part of the cooling system for the reasons mentioned above. -Ian Link to comment Share on other sites More sharing options...

What I SHOULD have done is listen to CW and suck with an SMIC!!! Dump the restrictive I/C in favour of a 2 Row max IMHO now you have it on - but this wont go away - it doesn't sound like the rad can cope with the heat soak now Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 7, 2006 Share Posted September 7, 2006 What I SHOULD have done is listen to CW and stuck with an SMIC!!! I am about to try and organize deposits for my final batch of SMIC's. Not only does the FMIC resrict air flow to the water and air con rads, it necessitates the removal of the Toyota duct that feeds said water and air con rads, so the whole thing is a cock up. modern cars have rad intakes in the front end or the car absolutely NO bigger than vitally necessary, to keep drag low. Rad intake drag on road and race cars is a huge percentage of overall drag, so makers go to vast lengths to make the aperture no bigger than is vital. To place extra demands on that intake aperture or to remove that duct is to invite serious problems, as you have both discovered... Link to comment Share on other sites More sharing options...
supra matt Posted September 7, 2006 Share Posted September 7, 2006 have you got a water temp gauge mate? if so what temps you seeing? Link to comment Share on other sites More sharing options...
JohnA Posted September 8, 2006 Share Posted September 8, 2006 ...To place extra demands on that intake aperture or to remove that duct is to invite serious problems, as you have both discovered... ...Furthermore, the stock SMIC sheds the heatload in the driver's side wheelarch. The bling-o-matics shed it in the engine bay (which doesn't exactly crave for any extra heat:search: ) Link to comment Share on other sites More sharing options...
Pig Posted September 8, 2006 Share Posted September 8, 2006 When you guys are talking about over heating? Do you mean the water temps getting too high? I fitted a greddy 3row and a fluidline rad and have not had a problem yet! Link to comment Share on other sites More sharing options...
