Pinto Induction
I've noticed that some Pinto's run Carbs vertically (90 degree bend in the inlet manifold)... does this cause a problem if the car is
caught standing in pouring rain? I'm guessing water will get through to the carbs if using a foam filter???

They would be Weber IDF carbs I think. Basically DCOE carbs mounted vertically. Not that common I don't think for road cars. IIRC they were
used on some formula cars that used the Pinto.
I guess some form of horizontal air filter would negate the rain issue?

Like this...
I thnik they may also be used on Beetle and other flat engines too.

That's the fellows! Any idea what the pro's / con's are against standard side facing carbs?

simple answer is yes if water gets in it will cause havoc, I've already had to change one cylinder (replaceable on a bug engine) on my beach
buggy due to this. One solution is to fit upside down tubs over the filters.

don't know about the performance figures, but could you imagine those sticking out of the bonnet of a 7 style car, i think it would look awful!

Main ones are - normally longer intake manifold, harder to fit in an engine bay (unless its a beetle or porsche), much higher risk of carb icing due
to the increased distance from the cylinder head & they tend to sway far more when the engine moves in the mounts

with those you need to drill a hole into the top of the carb so the rain will not collect inside the filter (up to around 10mm deep) and then be
sucked into the engine when you start up.

I had one of these K&N filters protruding through the bonnet of a Dutton that I used to own. It was fitted to a 32/36 DG something or other
carb. fitted to a 2 litre pinto. I never experienced any problems with water ingress or freezing. The filters are cleaned and coated in the proper
oil (if looked after!) and I wonder whether 'It is it like water off of the duck's back?'
PS I do have a brand new 42DCNF twin choke downdraft Weber carb which will fit Pinto 2.0l manifolds. Bigger and better than the 38DGAS. Anyone
interested? I'm willing to sell or swap. w.h.y.?

Sure, Injection is great, but if you go bike TB's you're then adding a high pressure fuel pump, filter, regulator, swirl pot and ecu.
Then you have your manifold costs, TB costs and set-up costs.
Much cheaper and much more straightforward to just plug in a pair of 45's!

i did say bike carbs not tbs
have you actually seen the price of a full set up for 45 dcoes around a grand
bike carbs can be had for £50 make a manifold you dont need anything special for a pump standard one will do you dont need a swirl pot
do you work for weber or are you just on a wind up? yes injection is nice and you could still do it far cheaper than a set of webers

Ah... yes, erm... glad you spotted my deliberate mistake
Sorry - thought you were meaning bike TB's... no idea where I got that from mind you! Just one of those days I guess!

I'd be interested to see where you can get a comparative injection kit with all the necessary ancillaries (bike derivative or otherwise) for
less than the cost of a 45 set up. Even assuming you have no Carb bits to hand (unlikely if you started with a Carb engine), you can get a full
second hand kit for £350-ish and a shiny new kit with everything for £800-ish.
But anyway, what bike Carbs do you recommend... early Busa / Blackbird???
Cheers

IDA 40's used on some Rally Race 2000 Pinto Escorts 1973/4, used by AVO to clear either the battery or the brake servo both of which were front
right and left of the engine bay, later the battery was moved to the boot giving more space in the engine bay.
The Escort downdrafts used a shorter inlet manifold than the one shown in the earlier photo with the top of the carbs level with the top of the rocker
cover (just the carbs without trumpets)

Megasquirt - £200
TBs - £75 (I paid £40 including shipping for mine)
Jenvey Fuel Rail (if respacing to DCOE standards) £50
All you then need are:
- Manifold (if you respace then a DCOE one works)
- Fuel Pump

So, assuming that a manifold and high pressure fuel pump will cost more than £25, then I'm right!
