  1. Looking good, but be wary of any airlocks in the top section of the cooler due to the way its angled/situated. As the core is very high in the engine bay, you really want to have the water inlet/outlets facing as vertically as possible (so air does not get trapped in the core, though it may still get trapped in the pipework if looped back down on itsself) and the tank needs to be the highest part in the system (which may be tricky.. - where are you going to put it?)
  2. Strange, Ive never had a single pump returned, and you can bet your bottom dollar 99.9% of them came from me :wink: The pump is a magnetic drive, so no physical connection from the motor to the inpeller, so there is no way it can leak, no shaft to break, no seals to rupture, no odd loads on any 'bearings' that can fail, no way it can go 'out of balance', it doesnt affect it if it 'runs dry' etc etc.... The only thing that could go wrong, is if simply the motor simply decides one day to stop, but as the motor is designed to run at 100% duty, and is a beefy unit that doesnt even struggle under high loads, this is highly unlikely... As for the pressure drop, its one of the lowest, sub 1.5psi, even when maxing out the rated flow of the core at 20psi + ...
  3. Really? :? Sorry, what I mean is its just a logistics thing, rather than technical.. :wink:
  4. Yeah, any idiot can fit an intercooler :lol: I think the problem is too is so may people have fitted CC's in the past, f*cked it up, had bad results, and then people tarnish chargecoolers as being 'crap', when in fact there are so many advantages - if you know what your doing 8)
  5. Yes, thats the point, most people won't run boot mounted tanks so its advisable to run large piping to get the most capacity.. But in a big system, don't worry about water flow slowing down in a large system, as the advantage is the water flowing round is cooler as there is more of it, so its 'swings and roundabouts', but more water will always help heatsoak issues.. 32mm is overkill... I only use this on the drag setups with the massive 6" and 8" cores which have matching cores with 32mm inlet/outlets. 25mm is the most advisable for road car systems.
  6. I don't see your logic. First you say a huge tank is important, but then you think that water volume in the pipes isnt. :? Use a good pump and the flow isnt a problem (or even an issue)
  7. Yes, thats right, though a big water tank isnt the b-all and end all, as you can generate alot of water volume through lengthing the coolant system and increasing the pipe bore. 25mm tube is 2.7 times more water volume than 17mm, and it is actually IN the system, rather than being part of an external 'resevoir'. Some of my larger CC kits use 32mm throughout.. Whats going to lose heat quicker away from the hot side of the CC, 2m of 17mm or 2m of 32mm which has 3.5 times more water in it to absorb the heat...:wink: Also, if you move the water tooo fast through the pre-rad it may not be to its full cooling efficiency, but it has to be going at a fair rate of knots....
  8. Not really, slightly bigger is better, but huge tanks are not really nessecary as the tank will go in the cold side of the system, so its not like this large volume of water in the tank is cooling 'hot' water from the chargecooler. It would only work to that advantage if your prerad wasnt doing as good a job as it should be and the water coming out of the prerad was still hot.
  9. There isnt high pressure in the system, but enough if hot to blow a push on cap off. What does this washer bottle look like? Is it a flimsy plastic thing or hard resin formed like a header tank?
  10. Yes, that should be fine. :)
  11. Hi What do you mean 'combined' water tank?. You don't mean both at the same time do you...? Really, the header tank needs to have an inlet and outlet, not just a single feed as it makes it easier for the air to bleed, and just be as high up in the engine bay as possible. There are a couple of VR6 installations on my gallery page. If it helps though, I have a new model, the 6x6 which allows high CFM/power capabilty, larger inlet outlet diameters, and the overall length is slightly shorter than the 4x10.
  12. You might want to try larger bore piping. I use 19mm on my kits and even upgrading to 25mm means nearly an extra 80% volume of water in the system, and the pipework makes up the main bulk of the water volume, after a big tank. What pump did you use?
  13. Quick, someone ask a question about Pamela Anderson..... :lol:
  14. One of the Daves... :) Yes, theyre fine for that power level. The next size core up are very good, but of course the inlet and outlets are 76mm thus you need to up your intake piping size. Ive just added a 6x6 unit which isnt too expensive and still quite compact (same length as a 4x10)
  15. Hi. First post an' all... The CFM isnt strictly true. Just because a head on a flow bench can flow over 400, doesnt mean in application on a running engine you are actually going to see this nessecarily... Rule of thumb is 400cfm is around 300bhp. You can flow more than 400cfm through the chargecooler units, but of course you are going to increase the pressure drop, and the air speed through the core is going to increase to a level where it is harder to cool. Its a 'reccomended' figure, not a limit. :)
