I hope this is ok ?

A little short on words, but u'll get the picture.

Can you tell us about what powers the beast?

Nice photos and vids there Roger.

Did you ever think of feeding the webers with cold air from the side of the rad through a large pipe. I cannot remember the formula but every 5 degrees reduction in temperature equates to a few percent increase in power. It also makes the engine more detonation resistant so you should be able to run more compression or timing.

Automotive breath,



It has a pinto, 2 liter head, T 10 block. 38.1mm & 45.5 mm valves, twin 45s, 40 chokes, TRW 11.5 pistons, head planed to get 12.5:1

The whole story......specs way out of date now..........

Visard should be able to recognize it he wrote 2 books on them.

His hair was a little different color, back then




Tom,

U can see a hole in front panel there, for air...but so many changes...so fe w hours to do all this these days.

The trumpets don't allow K&N filters any more so a whole rethink of induction is on the cards including inlet manifold as u know.


In fact...... a new engine is getting closer all the time

Hey guys,

Had to get my ten cents worth in here. That model Escort and the one that came after were, in RS spec, one of the funnest Fords of the era to drive. I used to reckon they were the nearest thing to a rear wheel drive Mini. For a short while I had the model after the one shown above. Made 182 hp at the rear wheels and could smoke the tires all the way through second gear. Ran a high 13 at Santa Pod at just on 100 mph trap speed in street trim.

These two liter Pinto motors have a lot of potential. Much better than the 2.3 US Pinto engine. With reletivly low buck 2L motors we were still winning races in 92 against 2.3's with megabuck mods.

I did a bore and stroke job on a 2L to bring it out to 2.3. Used a Piper twin cam conversion on top of that big inch bottom end. It was turned up to 11,000 to test the valve train (was OK) Final #'s were 193 lbs-ft and 249 hp.

K&N filters can be used with S/Draft carbs if the right stacks are used. Check APTfast.com.

By the way I was just 33 years old when that front cover was shot. That was 31 coming up for 32 years ago so, for the guy (no names here) who mentioned my hair has changed color - --- at least I still have hair!


In closeing let me say the 2 L Pinto engine was an undersold engine by Ford. It had so much production line development potential that was never persued. Instead some young engineer/s wanted to make a mark and the 2.3 came into being - The cylinder head is a disaster and the rest of the motor is somewhat dubious!

Last point - Fuel droplet sizes. Measuring these in my shop has always been a problem. The only gauge I have had is high speed photgraphy and analize the enlarged photos. At best it is dicey but it does at least show better from worse and good from bad. As for size - good question - the hotter the engine runs the less droplet size figures into the equation. If you want a really good fuel atomizer check out an SU or Stromberg constant vacuum carb. If I were going to enter the 100 mpg carb designing conmtest I would start with one of these two carbs.

This is my idea of an air box for webbers.................




The Piper twin cam conversion, for people that dont know, requires the cam towers removed [milled] and the conversion fitted to top of head.
This is a rare item, now, though I am told Piper cams still will grind cams for it.
Note the gear driven cams and therefore lack of easily phasing them, as a downside.
And that the air still has to go through that horrible inlet port.

Hopefully, with this boards help, I can enhance the flow of the thing



There were a few different manufacturers that did twin cam conversions donefor this engine.

As for crack about hair ..........merely stating uve been doing this for a long time.
