Ok i have acquired a mk1 focus with a 2.0 black top.
all i intend to do with it is rip the engine out to use as a dyno mule.
what i want to is run it on the dyno at minimum possible cost, so i dont want to buy sumps, flywheels, etc.
the dyno uses a T9 bellhousing.
im hoping i can just hack some of the alloy sump away to fit a starter in the normal T9 position, and keep the zetec flywheel, if so what starter?
you can do that yes , its the lrs 707 starter or possibly space a pinto one back 15mm
excellent thanks mike i knew you would know.Originally Posted by alladdin
the plan is similar to some of the pinto tests, bolt on a cheap rwd exhaust, run it up on the standard intake and fuel system on my spare emerald ecu, blagg an oval racing intake from somewhere to fit a 32/36, then move on to 40/45's or maybe throttle bodies
i can help if you dont have the T/b spare when readymaybe the 5 progression 45s too ( non weber)
thought you would say that, yes would be good, will keep you postedi can help if you dont have the T/b spare when ready
That would be interesting to see a 16v engine on the Dyno for a change as I think you have covered every possible aspect with the Pinto engine now, maybe we might even see a Duratec going on at sometime.
I always fancied fitting a Zetec out of the ST 170 with VVT delete into my Escort but as yet it hasn’t happened. I have also got some Duarte’s parts somewhere that have been mislaid, including a dry sump kit but again it’s never happened. It just seems a lot less hassle to leave the Pinto engine in for now.
ha ha, not done with pintos yet! ive got distributor tests coming, along with a split weber test. a test using standard efi intake, so lots still to come.
a few zetec tests appeal to me because its fairly cheap and easy to do.
thats not to say i wont do a duratec, but as i cant even bolt one on the dyno and no one has yet asked me to do anything with one its not overly likely to happen in the near future
The split Weber test sounds very interesting Graham, however I don’t think there’ll be a great demand for them somehow. I do admire your enthusiasm for the Pinto engine, all the tests you do including swapping parts takes up a lot of time and money.
If you ever get around to Duratecs I have a base 2.5 Ranger engine I bought with no ancillaries you could use along with a 2.0 high port head knocking about somewhere.
cheers, the split weber testing will be on the behalf of someone who makes engine kits, who might also have a 2.5 pinto in the pipeline.
tbh i just like testing interesting stuff
TBH Split Webers for me are a travesty - I know why it was done, but shed a tear when I see a DCOE chopped up just for a straight shot down the hole - this was mainly on Cooper S's especially as I doubt if the 'actual' difference was measurable beyond reasonable doubt?cheers, the split weber testing will be on the behalf of someone who makes engine kits, who might also have a 2.5 pinto in the pipeline.

in this case the weber will be a chinese webers, so is that ok?
there must be some gain on a pinto or the likes of Brooks would not be cutting them up for road rallying, on a pinto splits do give a much better shape to the inlet compared to a lynx manifold, but the lynx does in theory do a better job by compensating for the firing order
We actually managed to fit a brand new set of 48 Dellortos to a Pinto engine with a split manifold without cutting them, the carbs were very close to the bulkhead but everything cleared okay. In the 80’s there was Carburettor dealer advertising in Motoring News brand new DHLA’s at a very reasonable price but I still couldn’t bring myself to cut them up. When the Rules changed in 1987 and the Motoring News Road Rally Championship came to an end we fitted them back has twins to a NA Cosworth engine for stage events.
The split Dellortos performed much like a pair of twins unlike the poor performance of a single 45 Weber with its massive mid range flat spot. I can see with a 2 port A series Mini engine on a long swan neck manifold with single 45 or a pair of splits power being very similar.

We'll just have to wait for the results - it'd be nice if it was one of those myths - spend loads for a 1hp gain LOL!
The splits have far better drivability than a single side draught on a Pinto, I have no experience of the A Series engine on similar carburettors.
I have a single side draught manifold somewhere that I used in the mid 80’s for Road Rallies if I can find it. You are welcome to give that a try on the Dyno Graham if you have a single Weber to fit on it.
Always wanted to try a single Weber on a Lynx manifold but the opportunity never arose. Friend of mine did try this on a Pinto and after some fiddling with tubes/jets he said the engine performed very well incl. drivability.
thanks, i do have one and even fitted it, but it didnt perform as expected, same torque as 32/36 less top end, but the engine had also started to breath heavily i suspect the scrap yard test motor has broken a ring, so i will have to try again on another engine
No problems Graham, I look forward to the results especially when you get the big engine on the dyno.
