Sharpie Posted July 2, 2005 Share Posted July 2, 2005 Not sure if I like the look of this.... http://www.boostaholic.com/supra/cooling/radiatorscoopsnew.jpg http://www.boostaholic.com/supra/cooling/airdam2.jpg Taken from here: http://www.boostaholic.com/supra/cooling/ Just for info Link to comment Share on other sites More sharing options...

Zed Posted July 2, 2005 Share Posted July 2, 2005 That flap is seriously going to get forced back when travelling at speed, and maybe even cause the car to become unstable at a sufficiently high speed. Just today I ducted my fmic so that all the air that hits it is forced through it without any chance of escaping around the sides, which will hopefully mean that more air is now hitting the rad.

Terminator Posted July 2, 2005 Share Posted July 2, 2005 What a muppet. Looks like a Nova mod. I agree, at speed unstability could be a real issue. Link to comment Share on other sites More sharing options...
b_have Posted July 3, 2005 Share Posted July 3, 2005 I made a intercooler 'stuffer'. This sits in the nosecone and totally seals the intercooler so that all the air is forced through it. Together with the undertray that I made and the forced ducting to the turbo compressor housing, my cooling is becoming pretty efficient. Link to comment Share on other sites More sharing options...
Zed Posted July 3, 2005 Share Posted July 3, 2005 Is that intercooler stuffer made from expanding foam, did you shape it on the car, seems like a difficult product to control. Got any pics of the turbo compressor cooling ? Cheers mate Link to comment Share on other sites More sharing options...
b_have Posted July 3, 2005 Share Posted July 3, 2005 Yes, used expanding foam in a huge bag so to get a perfect,then cut the opening and sealed to make it waterproof. The compressor cooling is fed from the Bomex 'spotlight' intake to the underside of the compressor housing. Link to comment Share on other sites More sharing options...
Ian C Posted July 3, 2005 Share Posted July 3, 2005 That's a good idea Charlie I like that. I used reinforced plasticard strips cut to shape on the sides of my IC, the undertray sits flush at the bottom, and anything sneaking over the top (and it'll have trouble as the IC is much higher than the intake apeture) gets deflected off the cover panel and into the radiator anyway. Question - if you are that concerned with cooling, why have you junked the stock fan and (I assume) put in an electric one? When this is a known big step backwards in cooling effectiveness? -Ian Link to comment Share on other sites More sharing options...
Syed Shah Posted July 3, 2005 Share Posted July 3, 2005 It may not be a good mod, but lets not go slagging the guy off. He knows more about Supra cooling problems and has more track experience than all bar one in this thread. He later made changes to this setup, that did work on the track. Trial and error, he was not on a trodden road. Its easier to criticise him than innovate yourself. Link to comment Share on other sites More sharing options...
Ian C Posted July 3, 2005 Share Posted July 3, 2005 Was that aimed at me? I was hardly slagging Charlie off, I'm actually interested in his reasoning for putting an electric fan in, which is why I'm asking him... why he's put an electric fan in -Ian Link to comment Share on other sites More sharing options...
Wez Posted July 3, 2005 Share Posted July 3, 2005 I thought the new AAP fan setup and shroud actually flowed more air than the stock fan. If so would this be a good mod as it takes the fan load away from the engine. Link to comment Share on other sites More sharing options...
b_have Posted July 3, 2005 Share Posted July 3, 2005 One of my first mods (over six years ago!) was to lose the stock fan, I like the thermo-control twin electric fans. Have to say, they have been faultless in all that time and provide loads of space infront of the engine. Link to comment Share on other sites More sharing options...

b_have Posted July 4, 2005 Share Posted July 4, 2005 Ian, is it such a bad thing? I vaguelly remember people like Justin Fodden and Nick Phelps raving about this setup at the time, so just went with the flow. That was about five years ago!

Ian C Posted July 5, 2005 Share Posted July 5, 2005 If you have no cooling problems then no Can't beat empirical evidence I just know some people have had trouble with them - I recall the Paul Laing argument where he thought they were the best thing ever because the 10sec USA cars used them and even when the builder of the exact car he was mooting came on and said "it's for drag use only - it overheats with normal street driving" he wouldn't have it -Ian Link to comment Share on other sites More sharing options...

Keith C Posted July 5, 2005 Share Posted July 5, 2005 Which I would have thought would be less efficient, as the load has to go from mechanical to electrical and back to mechanical, rather than being mechanical throughout. Link to comment Share on other sites More sharing options...
Wez Posted July 5, 2005 Share Posted July 5, 2005 How does it impare performance by drawing more from the alternator? I thought alternators were rated to a set ampage and thats what they can deliver, if you are under that and then add these fans and remain under it how does that affect the performance? I dont think I am seeing the whole picture as I can only see the gain of removing the rotating load from the engine and these news fans also shift more air than the stock fan (according to some web info ):- This kit includes 2 of the highest flowing Zirgo fans available. The stock clutch fan produces 3,300 CFM of air. The dual Flex-A-Lite fans produce a low 1,200 CFM. This dual fan kit produces 3,350 to 3,400 CFM!

SteveR Posted July 5, 2005 Share Posted July 5, 2005 The more current you want to draw from an alternator (usually via the battery) the harder it is to turn the alternator, so the engine is therefore using some of it's power to overcome that, rather than sending it towards the wheels - hence Chris' comment about 'moving' the load.

Wez Posted July 5, 2005 Share Posted July 5, 2005 Just thought, does the viscous fan spin at full rate when you do a drag run or circuit, as there should be suffecient air flowing through the front of the car to keep it cool. With this in mind, would the electric fans only be used when travelling slow or sitting in traffic, i see on supraforums that they are wiring them in to be on constantly.

I've experienced no problems with them on normal street driving or on 1400 mile road trip just completed through Europe. As to pro's and con's relating to power issues, couldn't really tell you!
