Nic Posted July 6, 2002 Share Posted July 6, 2002 Go to: http://night-pager.com/ then click on the middle picture. It looks as though it links the top radiator pipe to the feed for the heater matrix at the back of the engine, would doing this improve flow and cooling?

Steve W Posted July 6, 2002 Share Posted July 6, 2002 IF the Supra is a pig to bleed-out the cooling system (as I've 'heard' on here), then might it be a way of aiding bleeding ? [Looks like TWO branches on the replacement top-hose and only ONE feed to 'matrix'/wherever - the 2nd branch appears to be what the 'plug' is for in the piccie ? - maybe the 'bleed' ? ] ps.

Nic Posted July 6, 2002 Author Share Posted July 6, 2002 I used Babel Fish to translate the description of the product, it came out a bit a garbled mess but mentioned something about reducing water temperatures by 5-10 degrees. Quote Link to comment Share on other sites More sharing options...
Steve W Posted July 6, 2002 Share Posted July 6, 2002 It can only do that using the matrix IF you have the interior heating ON... BESIDES, if the interior heating is ON then the matrix should be working at ~max.effeciency anyhow ! [it should be taking 'hot' water from the engine BEFORE the rad anyway - otherwise the matrix couldn't work until the stat' opens] Perhaps it's NOT going to the matrix at all but elsewhere ? I DUNNO' ? ? (looks impressive anyway - Blue silicon hose always looks FAST on the RS brigades ! ) Quote Link to comment Share on other sites More sharing options...
Terminator Posted July 6, 2002 Share Posted July 6, 2002 That car has some serious alterations, relocated battery, huge induction box thing and the water system. What else? Just a thought, the new hose is diverting some of the water to the matrix, thus increasing the operating temp. Does the matrix have a flow of air drawing heat away when the heater is not in use. Does the MKIV in effect have two radiators with heat from the matrix being blown away out of the car when the heater is not in use. Perhaps the matrix never works at its optimum efficiency rating. So by diverting some extra water the rating is reached. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 6, 2002 Share Posted July 6, 2002 Any company selling a "blow off valve" for N/A cars, basically a speaker and ROM based pseudo BOV noise, demands my utmost contempt. On that basis I figure it's to make a cup of tea whilst driving, or to fill your hot water bottle as you arrive at your destination. Seriously, the MKIV should not suffer any of the cooling problems the MKIII does, and no bizarre mods should be required, unless you have a FMIC, and basically some of these just plain mask the water rad. Getting rid of the air con condenser helps. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 12, 2002 Author Share Posted July 12, 2002 Hi Nic! I got the detail infomation for you. The Night pager stuff made by PentRoof Tokyo. I "OOPARTS" is a representive agent of PentRoof. The radiator by-pass pipe kit for 80Supra: This stuff make the water short-cut to the radiator, in order to make the water cool faster. I reccomend "upper type" made by stainless. The water by-pass kit: Y29800 This is an explanation from a dealer about what this thing does, you'd think that Toyota would have done this if it actually made a difference. Anyone understand how it would short cut the water back to the radiator? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 12, 2002 Share Posted July 12, 2002 Sounds a load of tosh to me. Toyota did a good job with the 2JZ-GTE engine, it doesn't need these sort of kludges to cool it. If the stock rad is masked it needs sorting, or a more efficient rad making. Pity your car isn't in the UK, I know I could sort it for you.

Nic Posted July 12, 2002 Author Share Posted July 12, 2002 Agree it does sound dubious, I saw one on a R34 and was curious about what it was for. I'm looking forward to having a chat about engine cooling with you, as you can see on the photo the radiator is completely masked by the FMIC. I've ordered a cover to blank off the gap above the IC to force more air through the radiator. Any other ideas with how to keep the engine cool with 36+ temperatures gratefully received.

Gareth Davies Posted July 12, 2002 Share Posted July 12, 2002 Nic, i've also got a fairly large FMIC on mine, and the way the previous owner got round overheating was to change the rad for a large (custom) ali version and fit a pair of suplimentary electric fans as well as the plate you mentioned. I can't tell from your pic if the bonnet is standard. Obviously UK weather is a tad cooler, but i've never had any kind of heating problems with mine even on hard track days.

Branners Posted July 12, 2002 Share Posted July 12, 2002 You can aid cooling a bit by taking the rubber strip off the back of the bonnet (ie just in front of the windscreen). I thought the air would flow out the gap but CW was kind enough to point out that its a negative pressure area and it will suck air in through the gap. Graham Dash tested it with bits of string and its true. Not sure how much air it would suck in but every little helps. You can also do a bit of work on the underneath of the front bumper to force air in, not sure how but there was a site for a buy in Arizona US who had done it.

Steve Cargill Posted July 12, 2002 Share Posted July 12, 2002 Originally posted by Chris Wilson Just a thought Nic, you DO have all the undertray in situ still? This DOES matter! Chris, what difference does this make? I don't have one, should I get one fitted then? Is there any difference between the stock one and I believe you can get aftermarket ones?

Chris Wilson Posted July 12, 2002 Share Posted July 12, 2002 The way underboonet hot air is removed usually depends a LOT on the undertray, it will have had wind tunnel testing by Toyota. Removing them usually impedes the flow, believe it or not. Hot air exit route for front engined, RWD cars is normally down the transmission tunnle and out the front wheel arches, the undertray is designed to help smooth this flow.

Steve W Posted July 13, 2002 Share Posted July 13, 2002 Mr. "42", WHAT THE *&£%*& does that all add up to ? ? I thought you said it was translated ? You've still left it in Japanese ! [ or Gobble-de-Gook] nb. Just a thought, but, IF the cooling was too bad, why couldn't you just ADD another radiator/ or/ just extend the pipework to give more coolant/better cooling ? (or FATTER pipes ? ) MORE COOLANT = MORE COOLING (probably - along as it's still 'flowing' right) ? What goes in the spoiler hole where the IC used to be once you've got the FMIC ? An 'extension-rad' could go in there ? Just 'throwing-a-bone' again......shoot it down boys ..... ps.(*rajietah*) and (*rajietah'hohs*) you MUST have PUT that in....too funny to be REAL ?

Rich J Posted July 13, 2002 Share Posted July 13, 2002 Originally posted by Steve W Mr. "42", WHAT THE *&£%*& does that all add up to ? ? Probably Japanese characters that have no English equivalent I thought you said it was translated ? You've still left it in Japanese! [ or Gobble-de-Gook] It's an electronic translator, they come out with lots of shit but I though people would be interested ps. (*rajietah*) and (*rajietah'hohs*) you MUST have PUT that in....too funny to be REAL ? Nope those are words that do not have Japanese equivalents. In Japan often in such cases (especially with in modern or technical language) the word will be written in Japanese phonetic characters keeping the original (usually English pronunciation (well vagelly)). If you think those are funny the Japanese phonetic characters for Lancer (as in Mitsu's EVO) come out as “Ransar”. Quote Link to comment Share on other sites More sharing options...
