Jeez Darryn..... L.O.L.

It seems Darryn got a bit trigger happy, but I've deleted all the re-post's to clean things up a bit.

It seems to me that some of the posts against rear mounting radiators are a bit to concerned about the Level Playing field thing ,If you want to go there then how about we measure diff clearance to see what tyres you can run ,also should we ban all Hyd winches as its not fair for the poor guys running an Elect one ,how about coilover suspension ,Yea right" The Rules state it must look the part from the B pillar forward mine does but like all the tray backed Nissan etc from the B pillar back it would be hard to tell what it is so i dont see what the problem is in having a radiator on the back surely your not going to tell me it would make it less factory looking ? .

Bloody good point Stephen. I like that, lets measure diff clearance! lol.

Hi guys I can,t make the meeting so thought i should put in my thoughts.

Here goes . Yes AND no to the rear mount radiators. First I like the idea of keeping it in the OME position and under stand that some have over heating problems. I like what Darryn Bell said keep the the one in the front but add if you need too . This way best of both worlds and extra means more weight . I run a std OME radiator but have made it very easy to remove and is done about 2 times in a comp. I dont think i will fit one to the rear of my rig as i like to use it for different activitys and if i was going to fit one it would be small and out of sight . Big radiators on back look like trials trucks and mine is not a trials truck yet . If I did remove radiator from front it would make space for a big hyd winch na bigger PTO . My vote is keep it in front(OME) but can add to rear if needed.
And keep it in mind we build the style of trucks because we like that type for a reason. And saying I can,t fit it in is not good enough. We all fit things in small place.s.(Nigel reid comes to mind) HaHa Cheers Klembo.

Anyone who thinks front mounted radiators are not a problem has been in some other competition. Darryn has a quick removal option, everyone who has competed in Rotorua knows what happens after driving through a meter deep puddle. The very fact that some resort to auxillary radiators (rear or in cab) means its an issue. If anyone thinks that some vehicle types such as full body can't benefit from rear mounted radiators then have a close look at Darryns Rangie. The simple fact is that rear radiators are cheaper than open core radiators which don't block up so readily and also a lot cheaper than cooking an engine. It comes down to cost and safety. While we're expected to drive through meter deep puddles of radiator blocking muck then rear radiators must be allowed to curb cost and for the safety of the crews, for example Darryns steam encounter at Norwest. How many people would you wish that on?

Darryns situation at norwest was due to a closed cooling system minimaly vented and using a plastic reservoir bottle. this is the standard disco set up, if the bottle had been vented it wouldnt have exploded when the bonnet stopped containing it.
i think the front rad should stay as the main cooling radiator with a size limit on an auxillary unit. Like klem i dont like the thought of a full size radiator on the rear. we need to keep coming back to the reason and very first rule that the trucks are based upon

: "This event is open to vehicles that represent OEM (original equipment manufacturer) production based 4WD vehicles. They must be certified road legal, registered and warranted and have third party insurance cover."

the more you are changing the rules the further away from this first rule we are getting!

Good idea about allowing secandary radiators but limiting the size! Some more discussion around that could be a good compromise.

And a rear mounted radiator effects none of the above.

Why does battling blocked radiators need to be a part of our sport? I dont see where the fun is in that?

why can you not fit a blind in front of your radiator to stop the mud n s*** getting in there??? it seams to me that sticking the radiator on the back is an easy way out. youve all managed so far with it on the front, yeah there is a bit of work cleaning them from time to time but it looks like youve got that worked out with spares and quick release fittings. what about the rotorua mud eating alternators? next thing we will be debating mid mounting engines!
its not about leveling the playing field, its about keeping "winch challenging" PRODUCTION BASED, its so that when joe public sees the event on tv or live somewhere ie the kumeu show special stages or even driving between stages on public roads, he can easily reconise the make of truck he likes go down to his local dealer and buy one put some mud tyres on and be very happy. the whole concept behind it is not to be "buggie style" hybrids, thats for trials.
looks like theres a bit more to be discussed on this issue.

Seems this has been brought back to life. Have peoples attitudes changed at all???
Again does it really matter or is this another thing that Challenge class should keep and just make it a rule for this new class that is again gaining ground???

Nope ,I still want to rear mount mine ,as of now i still havent heard a reason that imho holds water ,most of the rules go on about looking factory from the B pillar forward , well my rad woulkd like alot of others be behind the C pillar .most if not all of the people who are against this are either at present not a current competitor or havent been for some time ,or those driving full bodied trucks that would find it difficult to do this ,that to me is not a valiid reason .if under current rules we are allowed to have trans coolers,oil coolers tanks full of hot hyd fluid then surely it cant be a saftey issue as it will pass current wof standards dosent require a cert,so whats the real problem????
