David P Posted October 31, 2010 Share Posted October 31, 2010 Cheap alloy shroud with twin electric fans. New £69.99 inc P&P on ebay. Look the same as I have, fits a treat and been running for 12 months with no issues. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130426792196&ssPageName=STRK:MEWAX:IT#ht_1381wt_1026 Quote Link to comment Share on other sites More sharing options...

mawby Posted October 31, 2010 Share Posted October 31, 2010 Just a note from that advert... (Please note, these fan shrouds & electric fan kits are not a 100% direct fit, they will require some modification/fabrication, if you are unsure of how to fit please do not buy, please be aware of this before leaving feedback) Quote Link to comment Share on other sites More sharing options...
richarde7927 Posted October 31, 2010 Share Posted October 31, 2010 If you brought these were do you get the power from for them ( to get them to switch on when the water temp starts to get hot ). Rich. Quote Link to comment Share on other sites More sharing options...

Rich. Either an aftermarket ECU or a Fan controller such as http://www.demon-tweeks.co.uk/Motorsport/Cooling_System/Fan_Controllers_&_Thermostats/1847 Quote Link to comment Share on other sites More sharing options...
KrisM Posted October 31, 2010 Share Posted October 31, 2010 (edited) I have a loom and thermostat all ready to go for this. Very tempting. Would this only fit a standard radiator or will it go on the fluidyne? ta edit: after seeing demon tweeks prices i recommend http://www.x-eng.co.uk/X-Fan.asp for thermostat kits. Just need a couple of relays and away you go Edited October 31, 2010 by KrisM additional data (see edit history) Quote Link to comment Share on other sites More sharing options...
Nic Posted October 31, 2010 Share Posted October 31, 2010 (edited) Cheap + electric fans in the same sentence would worry me. They may work okay or they may fail, potentially leading to an expensive engine rebuild. I'd stick with a free mechanical fan personally Edited October 31, 2010 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...
David P Posted October 31, 2010 Author Share Posted October 31, 2010 I used one of these, they come in all sizes. http://cgi.ebay.co.uk/TOP-HOSE-THERMOSTAT-KIT-ELECTRIC-FANS-35mm-FITTING-/130449220997?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item1e5f612585 Fits in the top hose.

David P Posted November 11, 2010 Author Share Posted November 11, 2010 I have seen a set of these ebay alloy shroud and fans. They are identical to the ones I have, but without the Mishimoto badge and at half the price. Quote Link to comment Share on other sites More sharing options...

supra_aero Posted November 11, 2010 Share Posted November 11, 2010 surely if you have water temp gauges you should have little reason to worry if these fail. Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted November 11, 2010 Share Posted November 11, 2010 Always makes me worry if things appear 'too' good to be true. Usually is, hence why i will be buying Whifbitz's electric fan kit - tried and tested Quote Link to comment Share on other sites More sharing options...

David P Posted November 11, 2010 Author Share Posted November 11, 2010 (edited) Lovely engine bay David! What is the major advantage of having these over the stock? (Sorry for the dumb question). Thank you That's the snap that made the montage on the cover of the new calendar. They are quieter, only function when needed, which is when stuck in traffic or engine running without car moving. Free up power from parasitic loss, and give more room to get at the front of the engine, look good too. The OE water pump and viscous fan use around 13bhp, which is around 2mpg. Can't remember off hand for just the fan, because have changed both. I have been running a set of these for 12 months with no issues. The one's I bought have a 'Mishimoto' label on, and cost twice the price plus International shipping plus import tax. It is the same item. The only difference is the price: £440.63 + P&P + VAT ? or £69.99 inc VAT & P&P Edited November 11, 2010 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...

David P Posted November 11, 2010 Author Share Posted November 11, 2010 You don't need a dyno to work out that it requires power to turn a water pump and drive a fan. Quote Link to comment Share on other sites More sharing options...
davej705 Posted November 11, 2010 Share Posted November 11, 2010 You don't need a dyno to work out that it requires power to turn a water pump and drive a fan. You'd still keep the water pump wouldn't you? Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted November 11, 2010 Share Posted November 11, 2010 (edited) You don't need a dyno to work out that it requires power to turn a water pump and drive a fan. Well while that is true, you probably will only free up a couple of BHP if any moving over to electric fans. You see the Viscous fan isnt a "direct drive" unit, yes its powered by the engine but it runs on a clutch hence why you can move it when the engine is off... It will consume more engine power if its broken and turns the same speed as the engine, but a fan that is working correctly wont take away too much power from the engine. You probably claim more BHP from changing over to an electric water pump, what kit did you use for that, it was something i looked at a couple of years ago but never got any further with.

You probably claim more BHP from changing over to an electric water pump, what kit did you use for that, it was something i looked at a couple of years ago but never got any further with. The viscous coupled fan is engaged at all times once the engine has warmed up. I used a Meziere electric water pump, you can see it in the engine pic on the previous page, but should you decide to fit one, make sure that it is going to fit before you strip the engine! The one I bought had 4 bolt holes in the wrong place, and the U.S. is a long way to take it back. Details in my garage if you click on the thumbnails in the cooling section. In fact almost every 'made in the U.S.' component I have utilised has required re-engineering. Quote Link to comment Share on other sites More sharing options...
Matt H Posted November 12, 2010 Share Posted November 12, 2010 You don't need a dyno to work out that it requires power to turn a water pump and drive a fan. While that is true, 13bhp both seems optimistic and rather precise? I think Nic was wondering where that number comes from. Me too. Quote Link to comment Share on other sites More sharing options...
Nic Posted November 12, 2010 Share Posted November 12, 2010 (edited) While that is true, 13bhp both seems optimistic and rather precise? I think Nic was wondering where that number comes from. Me too. Yes I was curious where the figure had come from. If manufacturer's advertised claims on power increase gains for each of their products are to be believed, eg. exhaust, intake kit, electric fans, decats, exhaust manifold, lighter pulleys, etc. etc. and add them all up, I doubt the resultant dyno figure would agree.

Dnk Posted November 12, 2010 Share Posted November 12, 2010 13 hp loss using a viscous fan instead of an electric set up, hmmmm yeh okay i believe that, not Quote Link to comment Share on other sites More sharing options...
JustGav Posted November 12, 2010 Share Posted November 12, 2010 They are quieter, only function when needed, which is when stuck in traffic or engine running without car moving. Free up power from parasitic loss, and give more room to get at the front of the engine, look good too. The OE water pump and viscous fan use around 13bhp, which is around 2mpg. And what powers the fans and electric water pump? While you might see some gains, you still have to power the units and that means an alternator will now get the load instead.

David P Posted November 12, 2010 Author Share Posted November 12, 2010 (edited) I have just spent an hour searching, but could not find where I read the number 13. There are plenty of quotes like this though. "Here is my experience, when I had the 327 in my car running 13.10 with a best of 13.0 I was running the mechanical h2o pump, mech. fan and power steering. I swithced to elec. fan, moroso elect drive for h20 pump and put a manual steering box on. No other changes at all and car ran 12.50's and best 12.43 and mph went from 102 to 106 which is the best indicator of hp increase."
