TLicense Posted April 9, 2004 Share Posted April 9, 2004 All, On monday I went for a good day's hoonage around Brands Hatch. A Fantastic day, although a little bit hampered by April showers in the afternoon. Now when I first joined this forum I asked whether the stock cooling would be man enough to hold the temperature steady at WOT. (I would post a link to the thread - Don't know how) Well after 20mins of probably never seeing below 4000 rpm, and foot to the floor action, I pulled into the pits and low and behold, I was bubbling over. Now this could be one of three things as I see it:- 1. The stock set-up just won't take that kind of abuse. 2. The stock set-up is fine. My cooling system is up the swanny. 3. It was fine as I was caning it around, the lack of airflow when I stopped, associated with the heat built up in the engine, caused it to overheat when I stopped but would be fine at speed. When I say overheated when I stopped, there was a quiet bubbling noise coming from the engine area, and every now and then the stock rad cap would release some water. That was the only symptom, and the only time it's done it. I didn't see the gauge as I was driving. I was concentrating on overtaking caterham's on the straights. (Not so quick above 60 are they hehehe :flame Dev ) So basically I have three options:- 1. Look at sorting a better cooling system. 2. Look at getting my possibly knackered system fixed. 3. Don't worry about it. It's normal. Discuss... Regards Link to comment Share on other sites More sharing options...
Nic Posted April 9, 2004 Share Posted April 9, 2004 Tony, you could try fitting a new a new rad cap. I had similar problems when stopped after canning it, ARC rad cap sorted the problem. Link to comment Share on other sites More sharing options...

Alex Posted April 9, 2004 Share Posted April 9, 2004 Sounds like when my Radiator went south. IMHO get a new radiator. The stock one is fine for a stock car hooning about... This of course will raise the issue of whether to "upgrade" to a better radiator. IMO the advantages of a non-stock radiator are slim. And with the MANUAL radiator, that I now assume you'd get, they should be even slimmer. Most people would instantly say get a Fluidyne. I'm not convinced, they look good but there are better cores out there. Also the stock one has been made out of two different materials (I think about the time of VVTi's intro they produced a different rad), but I cannot remember the two options. PWR and Koyo also make aftermarket rad's (the Koyo being a similar price but much bigger than the fluidyne). If you want the best core you can get for reasonable money but are will to wait for them to make it you should speak to Docking Engineering they are based in the uk and have made a Supra radiator before. HTH - but by all means try a different rad cap first. Link to comment Share on other sites More sharing options...
Gaz Walker Posted April 9, 2004 Share Posted April 9, 2004 The best thing about Fluidynes is they fit exactly out the box, and they are bigger and lighter etc. PWRs are bigger again but do need a bit tweaking to fit perfect. Gaz. Link to comment Share on other sites More sharing options...
Wez Posted April 9, 2004 Share Posted April 9, 2004 Tony do you have a front mount intercooler? The stock rad has been noted OK on track days, I for example am running a stock rad and side mount and didn`t have any issues on track at all. With a front mount you are blocking all the airflow to the rad and therefore reducing its cooling effeciency, if this is the case then a larger aftermarket unit like the fluidyne should fix the issue. Best bet is prob speak to Paul Whiffin as he uses his as a trackday monster so he has setup for this purpose and as far as i know has no issues.

That was the only symptom With this bit of evidence I'd say get a new rad cap. Without proper sealing the boiling point of the coolant will drop so it'll boil easier. The rad cap oozing water out is as good a sign of it being shafted as you'll ever get Cheap fix hopefully -Ian Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 9, 2004 Share Posted April 9, 2004 If you have a front mounted I/C and want to use the car on track days you have serious problems. The IC only fits by dint of removal of the stock rad ducting, and also masks the rad core. It's the main reason I devised my uprated SMIC cores and tanks.

dude Posted April 10, 2004 Share Posted April 10, 2004 FWIW , i have driven the whole way down the M23 and A23 to brighton at lets say over 4000rpm early in the morning with an FMIC and trans coolers behind it and no overheating , i had my uprated rad fitted and it runs twin electric fans and temp never goes over normal .

Terminator Posted April 10, 2004 Share Posted April 10, 2004 Not quite the same as on the track:p I have had no temp problems with a stock rad with SMIC on the track. If you did a good cool down, before switching off, then its the cap or a new rad. Link to comment Share on other sites More sharing options...
TLicense Posted April 10, 2004 Author Share Posted April 10, 2004 Cheers for the advice so far chaps. I've still got the stock set-up. SMIC, and stock auto rad. I think I'm going to get me-self a new rad cap for starters, and take it from there. I'm thinking of doing another track day maybe in may, so that'll be the next "test date". So why are docking engineering so acclaimed Chris? I don't know who makes our cores at work, but IIRC we were looking at doing some pretty funky stuff, perhaps they'd be interested.

No termmy but prob. even more extreme , speeds between obscene and My god for about 15-20 mins as in WOT , try that on a track !!!

Syed Shah Posted April 10, 2004 Share Posted April 10, 2004 Yes Dude, but it is those insane speeds that provide the airflow to the IC and rad. A track is a much more punishing test of cooling. Link to comment Share on other sites More sharing options...

A track is a much more punishing test of cooling. My point exactly, insane sustained speeds mean insane volumes of air for cooling. High excelleration in short bursts and then slow corners robbing the car of cooling air then on the throttle again. If your cooling is not upto scratch, temps will go through the roof, then any iffy componants will soon show their weaknesses. Link to comment Share on other sites More sharing options...

Paul Whiffin Posted April 11, 2004 Share Posted April 11, 2004 Have you got an oil cooler fitted Tony? Link to comment Share on other sites More sharing options...
TLicense Posted April 12, 2004 Author Share Posted April 12, 2004 No. It's on the "to do", which unless you boys are offering interest free credit, will have to remain on the "to do" list I did actually speak to CW about running the lower piece of my auto rad as an oil cooler, can't find the thread, but basically he said I was talking nonsense (as I very often do) and not to bother. I saw his point and didn't bother. Regards Link to comment Share on other sites More sharing options...
Paul Whiffin Posted April 12, 2004 Share Posted April 12, 2004 Fit an oil cooler and your over heating problems will be history, it worked on my car anyway! I have them in stock here if needed.... Link to comment Share on other sites More sharing options...

I saw his point and didn't bother. Regards I fitted one of our uprated rad and an oil cooler and it seemed to work on mine too! These are not mega - and you can fit the oil filter relocation and dual sensor head on as well - to fit your oil temp and pressure gauges! http://www.mpaconsultancy.co.uk/miamirice/images/Oil%20Cooler1.jpg Give me a shout if/when you need one!
