Thinking of upgrading my standard IC, and wondered how much it costs, whether installation was expensive etc, and whether it could be a diy job?(like how do you tell the waters low? 
). - more room/easier access for rad etc? - Ian. And I also have the Roque Systems C/C that you mentioned. Some will also tell you that you would be better off spending your money on an uprated I/C. (Spearco) and the Rogue Systems/Pace C/C..... It has completely transformed the way my car performs for the better, leaving me with more power, more of the time and all of this even lower in the rev range than before! £1000.00, but I do think that in this case you do get what you pay for. ie a complete kit that has all that's needed to complete the install. The instructions included were not all that great to be honest but i'm led to believe that this has now been sorted out? In any case the kit is quite straight forward to fit. You will come across a small problem, as did I, when mounting the pre-rad at the front of the car. Simply because the pre-rad was designed to use one of the existing mounts on the air con rad. Some thing our UK cars don't have! It's an easy fix though with a little imagination He's car had the original prototype fitted to it. After some time spent on the dyno, it was discovered that Neils car had a restriction some where in the system, and all fingers pointed towards the Roque C/C core not being able to flow any more than 1.2 bar efficiently. However, it is thought that the core that Neil recieved was different from that of the one's made their after, for general sale. And that these are now able to flow up to 1.5 bar efficiently. 
(in so many words) that i've also fitted a 3S-GTE lump

How tricky is it to do - wondering where the pipework is best routed to the front of the car as well? Roughly how long did it take you?.... - Ian. I and a friend fitted mine in about 5 hours and I only think it took this long because the insruction led us in the wrong direction a couple of times But only because we had to make our own brackets to hold it in place. Running the pipe work back will explain itself once your under their, if that makes sense!? It would work out a fair bit cheaper to go down this route, but then you will need to fabricate a few bits and bobs to complete the install. Which is why I just decided to buy the complete kit from Roque Systems, because i'm lazy Wow..(the original was splitting - looked like a dodgy repair 
) and it took us ages to get all the bolts out, especially as the front wheel had to come off to get access to the wheel arches for a couple of the more obscure nuts? A fair few broke off too.. (if you don't mind me asking?) - I'll have access to a drive and a couple of trolley jacks.... £250... not cheap i know but it takes the best part of a day and plus it will be installed correctly ahem 'Mike' ahem. It is quite fiddly to do without the use of a lift but as mike has proved it can be done. ..a jack, four axle stands and a standed tool kit. All the work was carried out in a friends humble garage. We did it over two days in the end. On the first day we just mounted the pre-rad and run the pipe work back to where the C/C would be. On the secound day we fitted the C/C, accompanying pipe work and the pump (it was 345bhp), but Pete managed to find another 20lbs of torque!. I am getting 20 lbft of torque more than Andy even though he made about 60bhp more. I think this is entirely down to the Pace CC core cooling the intake charge MUCH better than the spearco, but also being much more restrictive. If Pace would just make the core 3" wider I think it would be fantastic, its just a shame that they made is so small!. The frustrating part is that there is enough room to make it larger - I am going to call them tommorow and explain my findings, maybe they will do something about it.- its just not big enough for the GT30+ guys. If you want excellent cooling and predictable response then you will struggle to find a better kit on the market at the minute. There are other guys working on alternatives but none are quite ready yet - I am hoping that one of them will be on test for the Rolling Road day at Noble Motorsports on the 26th March but we will have to wait and see... Does the pace CC pre-rad fit on cars with aircon?? Or do you have to ditch it? It was designed to fit along with it, ie it uses one of the brackets from the a/c itself. My car never had a/c to start with which is why I had make my own brackets to fit the pre-rad

Neil, what's the relevance of Muddly Talker then? Smile
- besides Muzza is a long time hero of mine - read that book cover to cover a few times now. He is an incredible man .. The outside dimensions are about 20% smaller than the Spearco although the internals probably look much different. I am just going down the route of swapping the CC core to prove it one way or the other. Especially since a restriction in the CC core would cause my symptoms. Knowing my luck it will be something else but until I rule it out my money is on the CC...Knowing my luck it will be something else but until I rule it out my money is on the CC.
.... Now i know this works as spearco chargecoolers have been used on very high bhp mr2 including the 1000bhp extremeboost car. "normal intercooler" flow channels.................just an idea.....xxxx wrote:
If you look at the other big chargecooler names like spearco and PWR you will notice the internals of the cooler is like on normal intercoolers with channels through the intercooler and small fins transfering the heat to the air, apart that there surrounded in a water jacket so effectivly have cold water remove the heat.
Now if you look at the pace design they have the boost air flowing through the small metal fins on the coolers faces and the water flowing through the
There is a chargecooler from spearco in a single core which is around the same size of the pace core and they rate this to a much higher flow.

surface to work with besides, I don't think the pace core cooling efficiency is in question as it appears to work. This is normal in a single core cooler - and is why it will be rated for a higher flow... Each individual core in the Pace cooler is effectively built this way. However, I believe the pace design is a 4-core cooler, one core stacked after the other, which is why the air path cross section appears smaller than the water path. not down the longest dimension. Greater open core area = rated for higher flow, though it may not cool as efficiently as the 4-stage pace design. The other thing to note about Spearco, is that all their cores are Bar and Plate not Tube/Fin which means Spearco can manufacture the core to have any combination of Air cross section Vs Water cross section they want
. They are not limited to the size of pre-extruded tubes as pace are.
