Justin767 Posted July 3, 2010 Posted July 3, 2010 Does anyone have a Radiator bigger than the standard Seight High Capacity one, that is surplus to requirements.?.
adamnreeves Posted July 3, 2010 Posted July 3, 2010 Problems with the high efficiency rad? Have you got the JE Developments thermostat cover?
Justin767 Posted July 5, 2010 Author Posted July 5, 2010 Hi Adam, I'm not sure if I already have the JE Thermostat cover... When I bought the car the chap mentioned that he'd done something with the thermostat housing (I think it had leaked and he might have just had it welded?) Do you have a photo or link on your build site to a picture of the JE one? Mulfab have sent me a big Email and seem well clued up on a bigger radiator.. Also they say they use a 16 Fan.. do you happen to know the size of the normal Westy one (factory built in 2003) As I'd re use my current one if it's decent enough.. Thanks.
Simeon Posted July 6, 2010 Posted July 6, 2010 As in my previous post I have a steel radiator for the Seight but this one is an inch thicker than the standard alluminium one. £80 and it's yours.
Justin767 Posted July 6, 2010 Author Posted July 6, 2010 Might be a solution. (I'll post on your advert) Maybe in conjunction with the JE Thermostat housing.?. What does that housing achieve? Does it just give better water flow or cure an air lock issue or something like that? I'm also thinking of sticking a little ball stop dangler valve in the heater hose so that all that water passes through the radiator instead.. - But is this water circuit in series or in parallel with the Radiator? Thanks.
adamnreeves Posted July 6, 2010 Posted July 6, 2010 Regarding the JE thermostat cover no photo required I can explain. Standard Cover, the outlet points upwards and to one side whereas the JE one comes straight out from the middle. Greatly removes the possibility of air locks. The top hose of the radiator ideally should never have to go down to the radiator, either level or up and this cover puts the hose closer to the ideal position. I reckon this has dropped about 4 degrees of my running temperature but also the temperature is more stable as it used to just go up 5 degrees and then dropped down, etc. A must I am also running with a restrictor instead of a thermostat. My running temperature is 82celius on my 4.6 with power output of 281bhp
Justin767 Posted July 6, 2010 Author Posted July 6, 2010 Thanks Adam, The Mulfab big rad option is already quite pricey, so if my engine temperatures are fine and stable - regardless of what I put the car through, I might save the JE housing for a later date.. PS what Rad have you used?

PS what Rad have you used? Sorry about delay Justin. Been having internet problems and missed your post. I am using the Westfield High Efficiency one with the accompanying puller fan. Seems to just about cope with my output so if you're higher than that then probably best to go for a Mulfab or docking Rad.
Justin767 Posted July 9, 2010 Author Posted July 9, 2010 I called a few suppiers and I've settled on Mulfab. Peter there has been very helpful. He knows his stuff and has been very quick to respond to Emails. He has supplied a radiator for years that works well but is a bit of a faff to fit and needs to sit reclined back by 33 degrees.. It also needs some expandable foam or something to stop air flowing past the edges of it.. So we've decided to give him my car for a while to use as a template to design a new made to measure super sized radiator that will cope with any power or driving situation Westfield drivers can come up with :-) It will use the proven principles of the Docking based Radiator - such as mounting the Oil cooler on brackets just behind the Rad where is gets far more air flow and also there's a heat exchanger effect that helps get the oil to the best temperature after cold starts.. It will also enable the use of the ducted nose to good effect - to eject the hot air away from the engine bay.. I'll keep the Forum posted on what he comes up with :-)
adamnreeves Posted July 9, 2010 Posted July 9, 2010 Excellent Justin. Keep us informed. At some point when I decide to up my power I will definitely need to address this area. I bought my oil sump off Peter and its a great bit of engineering very well designed and thought out, I know I quizzed him about all sorts when I picked it up from him. Very experienced and the welding and powder coating is spot on.
Justin767 Posted September 10, 2010 Author Posted September 10, 2010 UPDATE - In the end we stuck with the tried and tested radiator that Mulfab have supplied many times in the past. We thought that the new 'made to measure' design would take too long to get installed and I was keen to get my car back for at least some of the summer So the chap who's building up the monster engine (again!) dropped my car off at Mulfab and Peter rattled off this installation in just a few days - impressive stuff! But as it happens the engine tuner neglected to mention to Peter that he was heading off to Spain for 3 weeks and had no intention of collecting the car any time soon! (it's now been there for well over a month!) So a bit of a missed opportunity But on the plus side Peter says that the standard Westfield High Capacity Radiator has a surface area of 1220cm2, the redesign would have generated 1700cm2 but that the one fitted has 1800cm2 (48% above standard!) He's posted a couple of photos on his website showing the 2 radiators side by side - http://www.mulfab.co.uk/our-pro....adiator Check out that monster of a fan - it could power a small plane!? I believe that Peter has now used my nose cone as a template to design the made to measure Radiator, so if that is of particular interest drop him a line - but it would probably cost a little more and take a few weeks to complete.
