Ah, but Adrian you must admit they rooooly,roooly cool, e4specially on an SP. Are they useful? probably not but driving my car and watching those lovres rattle in the wind does something to one's libido. I can't remember just what....
Don't be so po faced. Please give my highest regards to your lovely missus and tell her I said "we will always have Southend on Sea"

My wife is having a great time in Bali.
I'm on the Swedish High Speed Train from Stockholm to Linkoping.
The active tilt system has failed and people are staggering along the train like drunken sailors as they make their way to the toilets or restaurant car. The carriages tilt passively in the wrong direction when the active system fails.
It's hilarious.
I'm staying glued to my seat, otherwise I would probably fall over.
I could do with a coffee though.

Adrian, am very aware your lovely missus is in Bali. She seems to miss you. So you took the Swedish job and sold your soul and left Paradise. Ahh! the drama though. And the new things to discover. Do it now as the years do drift by and suddenly you are sitting on a veranda contemplating the setting sun and louvres. Yes they are probably useless and are decorative. Like many beautiful woman i have known in my past lives. Took my Great Dane to a dog show today. he won special prize of being Tallest Dog in show.Tried to shag around three other dogs. Is too strong now for me. Missus won a first in a raffle after judging and got a very expensive soup maker. Seemed very surreal. Won another Best In Show for SP recently at show up the coast. Don't know why I bother. It makes the E Types and Porches very annoyed. Don't very much care now and really nothing really matters at al anymore. Am eighty this year and have had what can only be described as a very interesting life. Can't believe where the years have gone. The shadows deepen as Calver R. observed on his recent visit. Always do it now! Do you want a cat? kenny38 8)

Congratulations on winning all those awards.
Have you seen the Royal Albert Bridge, one of Brunel's masterpieces?
I crossed it on Saturday, on my way from not buying an S500 in Camborne, Cornwall, to not buying a CL500 in Chichester.
That big Westbury White Horse thing on a hill was a wonderful sight too.
Next time, I'll look at buying a car from a proper dealer at a proper dealership, offering a warranty, at a proper price, as I'm a bit tired of private sellers and a certain amateur dealer misrepresenting their cars.
No cats allowed in my building.

Adrian and Kenny ... you need to get a room together with some Cats and Goats and the odd wife thrown in with some Cups and Ornaments :D :wink:

On the underside of my fenders I have installed a material called peel and seal plus 1/8" foam rubber sheet to keep rock from leaving reverse chips or raised areas. My race cars would have rock marks showing on the tops of the fenders. There are no inner fender shields like most cars today. I will try to find some picks of the different panels I fabricated to make the air flow chamber. Hope I did not bore you. Just tried to give you a full idea of what was involved. The area was tight and will take a bit of work and time I feel it will be worth it. I have a few other ideas like disconnecting the hoses going to the heater core but do not forget to flow the water pump hose to the return side back to the engine. I will show you what I did on the the heater hose end

Obviously it would be horizontal the cut out is for installation of the alum vent. The location is low enough to install the nuts at the top of the vent all from the inside after the rear splash shield is removed. Joe.JPG

The top panel has to have a small cut out for installation. You install the nylon nuts and washers from the top. I used SS dome top Phillips screws at the bottom.JPG

What I easencially did was direct the hot air via a blowerdirectly into an enclosed box with the vent as the release area. The front and rear walls have curved faces to flow the air out the vent. With about 400 cubic feet of hot air per minute The factory placed the vents to evacuate the air under turblance and pressure. I will see now if I have made a difference RacerJoe

Hope I am wrong, Joe but after trying and failing over the years I have given up and now drive naked with all windows down so you are heroic in your efforts. Perhaps you are being like that old myth King Canute and the tide. Except your fate and. kenny38 :)

Great efforts Joe on tackling the heat build up.

You have mentioned previously the heat soak that occurs via the air box that is central in the firewall/bulkhead.

The pics shown of my car illustrate the area either side of the airbox (below the screen but above the silver sound proofing) where hot air accumulates with no where to go.

When i trim with foilcloth i will deliberately cut oversize in order to seal off these areas.

Appreciate your endeavours,Tim

I just recently drove my car in the 110* Tucson Heat to a car show.

My cooling fans are temperature activated by a thermostat with a probe that pokes into the radiator cooling fins.

My fans had been running steadily for ~15-20 min after I had shut off the car.

I opened the hood to show off the engine bay, and within 30-60 seconds of opening the bay, the fans clicked off.

So coincidence, or release of trapped heat? More experimentation to follow.

A few years ago I found that someone was producing an electric water pump that worked in conjunction with a delta switch. The idea being that when the rad water was hot both the fans and water pump worked together to dissipate the heat. Anyone tried that?

VW have them fitted to a few models and I also beleive the Vauxhaul Omega had one.

If you fit one they need to be carefully controlled. The problem with them as far as I understand is speeding the water up means it picks up less heat as it spends less time in the engine also as it spends less time in the rad it looses less heat.

Without going to the expense of one of these there are some very good mechanical water pumps for our engines that flow more than the original item. A high flow thermostat is also a good idea in my view and make sure your radiator is flushed.

I replaced my radiator a couple of years ago and the previous one had only ever had distilled water in the system, it was amazing how much silt was in the old one.

I think this is what I was looking at.

http://www.mawsolutions.com/html/electr ... pumps.html

The idea was to pump cooled water around the block in conjunction with the fans when they were running on. If it is not a good idea the website is interesting for bits.
