? About dickmeyer mpg cam

[UglyEd]

Definitely some food for thought didnt really think about that at all love the info dont know if i will revisit this cam in the future or not

I been looking at "torque issues" to with the factory set ECU.
There seems very little can do to tweak stuff, and I'm still researching the theory.
This is a very interesting thread BTW.

So far, if I was to "re-build" my 1.5L to my specs, it will require control of the tweaks and tunings, at the same time not to over spend or go over-the-top.

First port of call now is, because of, this mob's concept here

Yes, a "carburetor" that from my understanding "fuel injection".
I know the lads with the big gun V8's and endless buckets of cash are looking at these to.

So let's assume the factory standard EFI and ECU is ditched, replaced with one of those, and the rest of the motor can be re-built accordingly.

So it becomes, Carby, Head , Cam , Bottom Ends and Exhausts, all in control to tune and tweaks as ya go.

The standard ECU, ( I have asked around ), there is not much one can do, not even chip it.

My point is, if I still want to keep the same 1.5, SOHC engine and get as much as possible without having to go to extremes and replacing to DOHC etc etc, I'd now start at looking for one of those carbys, hopefully they make them to fit most engine requirements.

Of course the "new age" stuff is relatively new to me, don't mind being corrected.

[QUOTE=TominMO;728344]Had another thought today on the issues involving the Dickmeyer cam.

My car's issue was using it in an EFI setting, and the ECU apparently fighting the cam, then throwing a lean-fuel code and going into the rich limp-home mode.

In a Festy carby, I wonder if the famously inefficient carb intake manifold (too many turns) might be an issue. With the Dickmeyer FE cam drawing less air in due to its lobe profile, this might cause a lean condition because the lower suction can't do a good job pulling fuel from the carb thru the crappy manifold; so larger main jets would need to be used, which makes the whole effort pointless. A more efficient intake manifold might well solve the problem.

--One possibility would be adapting the lower half of an EFI intake with a custom upper that would let a carb be mounted.
--A simpler way would be to source the gen1 323 carb intake from Japan or Canada, if you can find one. It is inherently more efficient.
--Third method would be an efficient one-off manifold like one for a 4-cylinder motorcycle. Maybe instead of using a Weber or Escort carb, motorcycle carbs could be used. Possibly the m/c carbs could be mated to a cut-off intake mani, with internal sleeves to extend the mani and provide a good mounting interface for the m/c carb rubber mounting tubes.
--Possibly a stock carby manifold can be cut off a couple inches from the head flange, and then be used to make a better custom manifold. Perhaps the carb flange could be used too

Wanted to add to this and say that i think tominmo has touched on something here when i had the cam in i had very little vacuum. Was making my brakes feel like i was pushing on solid brick so with that said that cam defenitely was doin some strange stuff to my motor
