Re: DW's (new?) Sierra N/A PINTO race car

Ap aren't that expensive,I use a single 4 paddle cerametallic on mine,it gets lots of abuse including standing starts with a 2.04 1st gear and a 3.5 diff! I can get you a price if you want DW?

Yes please Nick. I know AP aren't a lot dearer than anyone else and the paddle should last a lot longer but at the moment any cash saved gives me a better chance of getting the car done.

Re: DW's (new?) Sierra N/A PINTO race car

Big thanks to Ant who popped over for a few hours today to help me start refurbing the rear wishbones.
We have one of them removed now and I just need to make up a suitable puller to get the old rubber bushes out that are a bit reluctant to give up the home that they have probably lived in for 20+ years and yes they are fooked

I have some new polyrace bushes so hopefully I'll get them in this week

The other good thing was Ant drove over in his mini and I've gotta say the build quality and paint is stunning.
Luckily it also matches my car so i think I'm gonna use it at race meetings as an alternative to a pit bike or quad in the paddock





Thanks for letting me drive it Ant, feels like its brand new. Needs a bit more power but not a lot as its great fun as it is

use a blow lamp to burn them out

Re: DW's (new?) Sierra N/A PINTO race car

Burn the rubber out with a blow lamp then cut the outer sleeve with a hacksaw and chisel it out.

Will let you know about the clutch,so you know which strength cover you want?

Cheers chaps, will try to persuade them out but like you say the outer sleeve may need to be cut.

As long as the clutch can cope with 200 ft lb and 250 bhp it will be pretty future proof. For now it needs to handle 160 ft lb and 190 bhp though.. so I think its a green one possibly??

Orange would be better,I've pm'd you with a price

Re: DW's (new?) Sierra N/A PINTO race car

****Right time for a BIG UPDATE!!!!****

The start of the race season is looming and with the car not ready yet and requiring a fair bit of money, that i don't have, to finish it, it is time for a big decission. If I get the car back to 2009 spec it would cost a fair bit as it needs a new clutch kit, exhaust system, most of the efi system to go on the throttle bodies etc and I then need the money for new tyres, race entries and a trailer...

This has led to a difficult decission to sit out some of this year and try to get the car to the spec I intended to run in 2011. As you all know the sierra is a bit of a fatty against the escorts and pugs, but now it is also against minis and fiestas that weigh naff all, so ultimately more power and a higher class is the way forward. The pinto is close to its ultimate power as a 2.0 so a new engine would be needed to get a good increase in power. It will be very sad to not use the pinto but there is no point messing with it and nicking bits off it when it is such a good package as it is.
To start from scratch my options were;
-N/A YB over 250bhp
-N/A Pinto, big cc, 2.4+
-302 V8, as used in he XR8
-YBT with sensible power, circa 350bhp

Once I sat for ages and weighed them up the YB and big pinto would need building from scratch with all steel internals, bigger T/Bs, and at least £2.5k+ of pro gearbox to be reliable. Big bucks in other words.
The 302 would be most simple but the engines over here aren't that cheap, need ally heads,new T/Bs, a custom exhaust and a fair bit of developement.
This all leaves me back where the car started before I had it, with a YB turbo being the best option. Now I love N/A for the track but theres no denying the cost advantages of using a sensible YB and it would make the car a bit more 'complete' in my eyes putting the right engine back in it.

So the plan is now set and I have a very rough idea of the spec i will run.
The engine will have slightly higher c/r, a T3 or T34 turbo, 2wd manifold, baffled sump and maybe cams. In other words little or no lag! The other advantage of running the YB is that the T5 box will be a lot less stressed than the type 9 tranx box so with this in mind I have already purchased a nice T5 from an equally nice TS member and soon the type 9 tranx box will be for sale.

Now that I've made the first steps of going YB I am very happy, but I must say that the amount of effort that went into the pinto last year is still greatly appreciated and hopefully it will end up in something like a light escort and really show its true potential

Re: DW's (new?) Sierra N/A PINTO race car

I've spent the weekend adjusting the car to suit a YB turbo installation. First of all the dry sump tank etc was removed, the engine mounts put back to their standard position and the rad moved back to make room for an RS500 intercooler.
Then in with the T5 box that I picked up earlier.





The T5 slotted in nicely as you would expect and i have fitted the prop so that the box now sits roughly in the right place, ready for an engine to be fitted (bare block, YB head and 2wd exhaust manifold for mocking up purposes)

I have moved the battery tray to the passenger floor well to make room for the breather tank that I have, which will hopefully work. The battery just requires a bulkhead connection and a couple of foot more cable and its done.

I am re-using my S80pro ecu and loom with the Yb(no dizzy) and already have a crank sensor, trigger wheel and MAP sensor read to fit. If anyone else has some useful ancillaries let me know as it would be nice to get the engine bay finished fairly quickly so that I can concentrate on theengine build up.







All in all a very good day, and lovely weather

Will miss the pinto but looking forward to hearing about your exploits on the track with the new engine.

I'll miss it too, it drove like a dream but unfortunately it needs to be in a lighter shell to get the best of it and the sierra ain't going nowhere In an escort it would absolutely fly and there was still a bit more power to be found by finishing the mapping.

Hopefully Graham will be involved with the new YB engine too and we have already discussed a few ideas that should work well.
Just need to rebuild Linford with its new bearings, rings and gaskets and then hopefully I can sell it to fund the start of the new engine.

Re: DW's (new?) Sierra N/A PINTO race car

good stuff,

i ve a fair few ideas on how we can build a yb with a difference, that will be very strong lag free engine which should be both bomb proof and enable dave to run very competitively

Re: DW's (new?) Sierra N/A PINTO race car

Nice one Dave, let me know if I can help out with the exhaust, I can sort you out with a re-packable box so you can keep your costs down

That would be a good thread to follow. If it is as good as Linford it will not be Ok. Might convert me away from the Pinto too.

Thanks Jon, will let you know pretty soon. Hopefully noise levels with the turbo should be good compared with the N/A engine. but time will tell.
