I will have some temp figures by end of Feb when car goes to Bruntingthorpe.

Mike,
is that 140mm wider than a rs500 core, or whole width?
wot does the scop actually do?

The scoop makes it difficult for the air to escape around the intercooler (as air will always take the path of least resistance), so forces it through the intercooler for better cooling.

duhhhhhhhhhhhhhh.... no shit sherlock
just cos your a norrrfok inbred we aint all that silly
have you increased the airflow from under the bonnet ???
did this small mod at the beginning of last year so i have an idea of what you did .. and possibly can see some room for improvement

Eagle, why would I need to do that? There is no more air going into the engine bay . Just that the air that is going into the engine bay, instead of being deflected around the intercooler / radiator, it's being forced through it .
I have seen no increase in engine bay temps by doing this - in fact both water temps and ACTs are lower than they have ever been before....

As with the pics I sent to you a few months ago, even the simple mod of cutting out some of the bulk-head plastic (simple job) and allowing air to escape through the slotted wiper valence gives very positive results.
I have lower ECT/ACT with these mods AND GT series turbo putting hot water back into the engine than I had before the bulkhead mods - and remember that was with the old T4 turbo that was not water cooled.

Doug,
Read my reply above .
I have even run the car with the inner headlights removed - and it makes NO difference.
As I have not increased the air flow through the engine (I've just made that airflow more efficient), I don't see the need for your mods at the moment, but I won't rule it out until I confirm full load temps at Bedford. However, at this stage, the road temps are lower than they have ever been, so it works exactly as I intended it to.

Thats what i was planning to do with my cooler as i need to duct the air into my cooler and rad to make it more efficient !!
Just never got round to the trip to pro alloy
Didnt you have a custom quad cossy intercooler mike ??
Must say they look better in black, thats somthin that i think will loo good when a get all my tanks done black aswell

I think we need to find a white bonnet that we can put lots of slots in (at the hinged end) I reckon that even if this bonnet did not have the Es Cos oval vents It wouls be more effieient in the reduction of the temps.
Mike, if I can get hold of a white bonnet and get it modded wiith lots of slots can we do some field testing with it fitted to your car?

Pete,
Think you need this back
Doug,
I think your mods are better and more in keeping what I would want to do (subtle). If I have any probs, then I'll go down that route first, but at the moment, it's looking pretty good .

Pro-alloy one is the only thing i can say, top job on the finish and flow
Will also try to do those upgrades as mike and doug are writing about, should be fun to se what it changes on the 1/4mile

Cheers Mike.
i've run a 2nd rad for over a year, and the only down full is wen stat shut, the water is still passing thro, so if warmin up whilst moveing, takes ages. and on motorways wont warm to over 50oC unless i stop and let it warm to normal temp, and carry on my journey.

Danny,
If you compare the front of your car to an Escort, it's pretty obvious why this is . I could have fitted a WRC bumper and that would then see similar temps to you, but it would also create a lot of drag at high speed (due to the big frontal area/lack of exit area), and I would definitely have had to do the mods that Doug mentions, as so much more air would be going in to the engine bay.
How is your rad connected, or is it a turbo-cooler one?

I have removed the water-cooling from my turbo, and my auxiliary radiator is fed from the head, so is a "true" supplementary radiator .
Your cooling system is already compromised by having to deal with the turbo . However, given the temps you're seeing, I think you can safely say you have cracked it . However, I attribute that more to the design of your front bumper. Unless you're prepared to do something similar to a Cossie, then the Pro-alloy item is the way to go .

mike, by doing something to allow the air to escape easier, you will actually allow more airflow in to the engine bay, as the pressure difference between the bay area behind the coolers and in front of them will be reduced.
i'm not sure that the vents at the base of the screen are the right place to do it though normally, that area is a high pressure zone to force air into the cabin for ventilation and out through the rear inner wing areas behind the back bumper where it is low pressure.
if you allow the engine bay air into that area, i think a lot of it would be drawn through the cabin making it hot and possibly fumey (spelling, or is that even a word?)

at mo, AH fabs are sortin a new twin past rad, and i'm lookin at new core and tanks for inter.
on low boost 18-23 (didnt change temps much)
on a hard 10-20min track seesion my coolant saw a consistant 92-93oC in 27 ambients with my twin rad setup. and 38oC ACT's
but with a std escos rad on its own fitted, saw 93oC coolant temps on 15-30 mins session at brands with 6-10 oC ambients. and 34oC ACT's
yeah bumper helps,
it went from 48 oC act's before i cut it out, to 38oC at same boost, ambients and inter/rad set up, and coolant dropped 2ish oC also.

Doug Stirling good. it's all well and good saying that theory says this and that, but doing it and testing it is the only way to know.
what have you done with the blower during those 2k miles doug? general use, including some at max speed, or just low speed?

didn't know that. so the vent at the rear of the front wing is a functional item as it's in a low pressure zone to draw the air out from the engine bay?
i always imagined it was just an aesthetic thing
