Good luck with the mapping tomorrow Ben, the first time the new engine will see the red line?

What a massive anti-climax.. :evil:

Image

Drove it no problem in the heat yesterday afternoon to TDI, parked up and walked in. They take the car into the dyno cell, prep the car and bolt it to the hub dyno, meanwhile the radiator decides 'I don't like you' and feebly wees onto the floor. So didn't get very far with that one, car is unloaded and I call the AA who once has a look, decides best not to try any sort of rad-weld and takes us home :ok:

It seems like the core has failed, cracked around a row of two at the end. Whilst waiting for the AA I phoned pro alloy about a new one, of which they were extremely accommodating to my tight time frame (I had already booked the car in again for 2 weeks time - cutting it fine!). I decided to waste no time and drove the old rad to them this morning so they could see what additions had been made to the otherwise alloy Escort Cosworth radiator. I'd also decided on the phone that I would sort out the mounting of the fans and this led to getting one of their fan kits perfectly suited for this rad.

And I left, £700 lighter :cry: :cry: :cry:

I'm really hoping I start running out of bad luck soon.

I am supposed to get the radiator on the 29th to allow me enough time to fit and check. Fingers crossed they meet the deadline.

Barry, yes it would have been its first full sweep, I've only had it to 4k :-)

Oh oh.. Not good! Hopefully they will source you the radiator in time! Ford Fair is getting close now :lol:

Hi Ben
One of these days you might get some good luck, let's hope it's soon.

Very close - every year I've been with a car I've been rushing. I was in good time about 3 months ago before engine went :roll:

I hope so Barry, probably not that much bad luck but it certainly feels that way.

Still, Monday was very hot for an engine anyway so maybe it'll be a bit cooler in 2 weeks time and get a better result 8-)

So I've had a strange clock ever since I put this engine in 5 years ago. I've gone through everything, and things have changed anyway as the car has evolved. Last thing to try was the lower arms so I bought I set of genuine Ford arms at a great expense to swap with mine which have a spherical bearing at the rear and an uprated rubber bush up front.

Here are the new ones..

Image

Image

Unfortnately, they clonking was/is still there so definitely not those then.. So these are now for sale (have done less than 10 miles), see for sale thread.

I had also got some new punch bolts, as well as a new bolt for the rear torque link/lower gearbox mount.

Image

Next up, I picked up the new radiator from Pro Alloy on the way back from Lincoln last Thursday :-)

And here we are..

Image

Thanks to Dan for prepping the fan wiring and putting a new male Delphi plug on.

Image

Image

So all fitted, plumbed in and tested ok.. Although now my heater matrix has got air in it again and doesn't blow hot! It's also slightly thicker than my old one and so very close to the intercooler pipe at the bottom. I may remake the radiator brackets to give some adjustment and therefor clearance.

Next, I improved my oil separator pot. I welded a plate over the thread at the bottom as oil was seeping out.

Image

Then I changed the plates inside. This way the air has to change direction many times and should cause the oil to separate away.

Image

Dyno day tomorrow again, hopefully better luck this time!

Rubbish, just rubbish - well, power-wise anyway. Less power than before :roll: as far as I make out the short of it is, the engine is really built for a bigger turbo. All the flow work that's been done to the head is just making the turbo problem worse because the one I have is so small.

On with the good news, no leaks after nearly 4 hours on the dyno and all temps were fine. It's also nice to finally be able to drive on boost properly and use all the rev range. Although down on power it's still quite pokey.

Unfortunately, the next step will have to wait until 1, I pay back this round of bankruptcy and 2, get the funds to go for a new turbo, new inlet manifold, new injectors and nice new management with some active knock control.

The list is endless!

Also, might have found my knocking. Would be grateful is someone could get some photos of the drop links and anti-roll bar whilst the car is on the ground (preferably flat). I guess the photos would have to be from the front of the car to get access. Thanks!

TBH, I think anything over 250 bhp is in puma overkill anyway, and somehow I suspect you are north of that figure already :wink:
I would just make sure that engine is as driveable as possible and enjoy it if it works flawlessly

Hi Sinisa,

It definitely still has a lot of poke. The problem with the turbo has been accentuated by long duration camshafts and a high flowing head. However this now means that torque takes a dive after 5000 rpm and it's quite noticeable on the road.

It's only ever going to be a problem on dual carriageways and motorways at speeds which you lose your licence anyway. The plus is it drives like it has no lag, and the power is practically instant.

I'm wondering whether it's better in the meantime to concentrate on the chassis and handling to improve it further.

Of course it is! If I were you, I'd leave the engine alone and perhaps look for ST170 gearbox with additional gear to make use of that low end grunt :wink:

Probably for the best, as no matter how much power you have, you can't go fast upside down :lol:

That was a choice I had before getting the MTX75 box, however the ST170 Getrag box is nowhere as strong unfortunately, hence the choice was the MTX75. Shame otherwise I'd go for 6 speed every day of the week!

They did pretty much of ST170 turboconversions in the States, IIRC, so it should gandle 300-ish bhp, I guess? Or that, already, IS NOT ENOUGH for your engine? 8-)

I'm at around 300hp. The ST170 gearbox will take a bit over 400hp. But I plan my next power hike to make at least 400hp at the hubs, which in theory should be easy with the right turbo :-P

Hi Ben
I think you need 4WD or RWD now with that sort of power. Wheelspin must be epic in your car now with the power transfer.

My thoughts exactly. I would just refine it as it is and get a 6-speed gearbox in....

But I do respect the effort

Road legal slicks are my friend :lol: only spins in first and if the tyres are really warm, barely spins in first.

Also with new management I could get boost per gear :wink:

But I do understand where you're coming from. I'm chasing it because there are plenty of zetec turbo fiestas around rubbing 400+ (some 500+) hp.
