MK2 Escort LS1 in orange!

here some mk2 vented bonnet classic style.

or build in some channels in the side for cooling and airflow the headers/engine and let air escape passing out those type fronts panels ;-) (just kidding)

got escort cossy on mine, work a treat :-)

Decided to run as is and if gets too hot on track will lift the bonnet at the back or run without then fit vents. Will also fit timer relay to keep fan running for 10 mins after shutdown if fan was running before shutdown, as the standard ecu/pcm turns fan off when you stop the engine!

So you dont ruin your bonnet for no gain, The area at the back of the bonnet / base of the windscreen is high pressure when your driving.

Lifting the bonnet at the rear allows the high pressure into the engine bay and it reduces the airflow through the rad.

Rad only cools the water when air passes through it and if you have the same pressure both sides the air wont flow,

You can get air drawn out from the engine bay with grills set into the front section of the bonnet where the air flow is fast and low pressure so it pulls air out( and lets more air in the front)

The electric fan should stop when its cooled the water in the rad (assuming thats where the Temp sensor for the fan is)

Hot air does not escape from the back of the bonnet on modern cars, the grill is there let air into the heater

I managed a few laps of Croft at the weekend. I got on track after a day in a Radical turbo, 911 and a MX5 so was up to speed very quickly in the Escort which soon highlighted its lack of grip when on road tyres at normal pressure! With the right diff it feels it will drift all day if thats your bag! Temperature crept up but once I stopped reving it to the red line it started dropping off again. Brakes were spot on too. Now not sure when I will get chance to take it on track again as most weekends booked untill the backend of the year. So make me an offer!

great sound

[5potTurbo]

Car sounds great.

I did snigger at the video commentary, "I'm on him!", then proceeds to miss most of the car on the straight.

[DougMcC]

Ooh that sounds good!

Kurt's Radical?

[sheepdip]

Ah yes - you know him?

[edh]

Looks great Dave - shame it's not coming to Spa

Remind me to take you down to the auto engineering college at the other side of the circuit - they were just starting to restore an old Escort rally car when we were there last year. I wonder if it's still there?

Yup. He's good mates with my brother in law Jonny. Who I think has seen your car IIRC.

[sheepdip]

Fame at last! The Escort is the cover car in this months PPC. Really pleased with the story only downside is that there are no drive by shots of which we took loads with the photographer hanging out the back of the camera car. Also a mate from work stated that there are no shots of the rear end from the underside which he thinks is the most trick bit!

[sheepdip]

24 hours from removing the diff to try a change in the viscous fluid this happened! I was trying to show a mate how poor the lsd was by giving it some on a wet road!
So now skipping the uprated viscous route and going straight to the gripper solution. Just hope the 3.62 ratio is going to be Ok.

[sheepdip]

All change! Decided after taken tons of advice from the big power cossie boys I have ditched the cosies diff and gone for a Supra turbo unit. First mounting completed tonight - only 6 more to make!

[sheepdip]

[Caddyshack]

Good idea! Have you got the weir maxi spring kit in there, Bara recommends them along with seals and bearings if needed.

There is a group buy on passionford for billet rear cover integrated with the hanger as the top two bolts can shear and is the weak point. MK Motorsport is making them.

[sheepdip]

Cheers for that advice. The flanges are from MK, I did not buy the rest of the kit as I am not using the Sierra beam as you can see. But I did think that the rear mount could be weak when only using the two top bolts and I will be adding more bracing to pick-up the two bottom ones. I just need to think of a design that looks good as well as been functional.

[sheepdip]

Diff in and complete. I had a slight delay due to not realising that the MK side flanges are tapped standard metric and not fine. So just when I thought I was finished and only need to fit the cv joints to the flanges I had to leave it for a few days until some new bolts arrived.
I had one test run around the block last night and all feels very good but I was not keen on too much testing in the dark! You never know who is watching! But it holds a drift loads better than the viscous cossie diff as you would expect it also is not as noisy.
