- in this video we run through final tuning stages of our 2.3 pinto, we run it on 45 does with huge 40mm chokes, 48 does with even bigger 42mm chokes and finally fuel injection and make some pretty decent power figures along the way

What a banshee on the 48's, still climbing at around 8k. Superb engine build, I'll be honest in I didn't know these could be pushed this far, even in a race build. Almost brought a tear to my eye hearing her just want to pull on.
Ok, quick edit. I've seen the next pull but still beyond impressed with the engines desire to pull on, outstanding. 230hp and 190lb man, a cossie was 202 hp/lb iirc with a turbo. Mental.
That was really interesting, as usual. 👍. I had no idea a pinto was capable of those numbers
The real trick is getting to last at those numbers!
Wow!!!!, 225 hp in a pinto engine!!!!!! That are serious numbers!!!!.
You are the Best!!!
It is a nine minute video, but a lot of work and effort! Thanks for that, I enjoy it! I will start to build a 2 liter for my Sierra. Not this level, but much lower.
as i recall, from the 1990 ties, a dutch oval racer i know, had driven a high end pinto ohc 2050cc limit in the hotrod oval division, wich made up to 220 hp on 50 dco carburettors
Threw me off a bit not having this or the final injection mapping dyno pull videos named like the first 4 build videos (part 1, part 2 etc) but I’m glad I found the last two. Mad HP/L for an 8v engine!
This is an awesome channel. Well done
Sounds the business on efi! Keep up the great work! Cheers from 🇦🇺
Great videos 👍
That water pump belt was pumping
I want to come and play at your house lol great work man
the Generator Belt is flattering me :D
by altering the radius on the finger follower, you can change the cam specs so as to increase the velocity limit, with out damaging the follower or cam
Helpful info on the choke increase without needing the jet change. Its probably unlikely on the kart, but nice to know its a possible situation.
Thanks Grayham. 👍
The I did change the air and emulsion tube, so that could be part of it, but I suspect them main reasons are that the 40mm chokes were too big to function properly on the 45mm carbs, whilst on the 48s with the straighter intake manifold considerably more air passes through the carbs
@@PenguinMotors Thanks Grayham, updates here after testing in a couple of weeks.
Great work. I'm building a 2L for my Cortina P100. I think I might go the 45 route after all your tests.
if you dont go mad on the choke size 45's will give best all round performance
@@PenguinMotors I think you're right, what choke would you use? I plan to skim, port and polish the head, mild cam and let it breathe.
34 or 36mm, 34 will give better low speed flexibility the 36 might give more top end depending on how mild you cam really is
just to add to my reply i recently saw 148 bhp using a pair of 34mm chokes in 45's on a mildish cam, which goes to prove you dont have to have big chokes to make decent power
@@PenguinMotors sounds like a plan
One question: plus your excellent work all around that engine, what camshaft have that engine on it? .
Many thanks in advance!!
Regards
its a newman P6 very similar to kent HT1
Hello.great video I have 2l pinto in my MK2 cortina love the channel.just a quick question what is the best jetting for a 32/36.here is SA not much performance parts for pintos
It’s impossible to answer that it all depends on engine specification and altitude not to mention climate
100 brake per Ltr with a wide spread of torque. Look back in 50 years and this will be as good as man got with a mechanical device running on dynosure poo
congratulations 🎉🎊!
I wanted to ask you which exhaust manifolds are those in the video?
its an SRD manifold www.srdengines.co.uk/
Quick question I see a lot of Picture's of Webber Carburetors where the Trumpets have no Filters fitted as is the case on this One,doesn't this allow dirt and dust enter the Carburetors?and cause blockages to the Jets.
There an extremely small chance of that, 99.9 % of fuel jet blockages will be via fuel contamination. Even then as the jets are upside down with a gap under them it’s rare for anything in the fuel to find its way into a jet.Assuming you have the screw on jet covers fitted ( which I don’t bother with for dyno use) the only way airs could get blocked is if something finds its way through the hole next to the intake through the internal passages and up past the jet assemblies then turns 180 degrees to go down a jet holder. Much more likely anything going through the hole would simply end up in the bottom of the float bowl. In short you’re way more likely to end up with foreign material causing actual engine damage than blocking carbs
HI Graham - I am busy with a 2L pinto build for my Sunday croozing MK1 Escort - My bottom is stock standard with the head ported and flowed and will be running off 45mm Throttle bodies -
Can you please recommend a good profile cam to run off pump gas? I dont mind a rough idle as it isnt my primary car but dont want her to be a handful on pull away as well.
Much thanks & Regards
trouble is everyone has a different idea of what a good cam is! at a guess something with around 285 degrees duration would suit
What if you make the runner length the same on the 48 dcoe's as the efi?
i would expect the engine to react the same, however it may not, thats why you test stuff.
@@PenguinMotors Interesting. I appreciate your channel. Very interesting stuff on here. After watching a number of your videos, I was wondering if you have you ever heard of Keith Frank? He makes a device that replaces the emulation tubes on DCOE carburetors. He calls them Venturi Pump Tubes. They work completely differently than emulation tubes. Thought you might be interested in them if you're not already aware.
Do one have to use epoxy in the intake port to get to this level?
no port filler or welding whatso ever on this head
Hello, I have a standard pinto 205 2.0 with efi injection, but because I gonna put the engine in a capri I want to go with a 32/36 carb it’s otherwise not allowed for mot in Belgium) do I need a special intake manifold because of the egg shape inlet and are those available?
the 32/36 carb manifold bolts straight on to an injection head using the carb manifold gasket
@@PenguinMotorsthank you
Have you experimented amd tried e85 on the injection ¿
I tried E85 years ago, naturally aspirated engines don’t really benefit but turbo engines do massively. But as it’s not freely available in the uk there’s not much point in doing anything with it anymore
@@PenguinMotors oh that's a shame , I would have thought it was easily available via pumps at the stations.
Not in the uk unfortunatly, for a while one of teh supermarkets sold it, but then the government taxed it to death so sales all dried up
man... I had a 90's Sunbird boat with the 2.3 OMC. it was rated at 128 hp due to no emission controls. it ran great but man if it had some of these modifications it'd be scary on the water. I could only get it to rev to 4800. I imagine a hot cam and better carb would've woke it up. 160 hp sounds very doable ;)
can u post a parts list for this engine?
Cnc race head, Newman p6 cam, forged pistons, steel crank custom steel con rods
I hear ya on the intake length. So what total induction length did you end up with? The math suggests 13,5-14" but it would be interesting to hear what the engine liked IRL.
Did you play with the header to see if a different layout would make a difference?
Is this engine allowed to run an open header, or is there are noise regulation involved ? (I expect there is)
As a note to find even more usable power. A couple of Swedish tuners are pushing 250 hp out of the Pinto for track race engines, so there is something to be improved on. Those engines are lots of £££, Cam is a result of numerous attempts, heads are a work of art, but its possible.
Inlet length from head face to outer end of ram pipe was about 10.5 inches which is less than they normally like. Didn’t try open header as car cannot run like that. There is always something more to be had, this engine is conventional in every sense, so I’m sure more could be found, in fact we would have had more power if we were not in a heatwave when it was dyno tested, or could run better fuel to run higher compression
@@PenguinMotors So that´s something like 12,5" from valve to ram pipe opening. - Yes, its not "long" for sure, but not too far from the math either. OK on the other stuff. There are almost always limitations.
mayby some dyno with 205 with volvo 2.3 redblock head :?
interesting thought but why not just use the whole volvo engine? probably stronger and cheaper?
@@PenguinMotors block are similar , and heads fit Perfect but Volvo 16v are shorter and need some welding to do that.
Just dont like swaps
ok, trouble is volvo 16v are not common here
@@PenguinMotors here also. From time to time they are on eBay for 500-800$, so its much cheaper that yb or warrior head
pure automotive pornography, nothing to add...
