another injector ?? sorry

Post by toon2 »

I am trying to find the right F injectors for my conversion. Reading the megamanule, it says to find injectors off roughly the same HP motor. There is a motor that produces 3 HP less than mine but is also 200 cc smaller.

With the calculator I can get the lbs/hr(10.3) that my motor will need but I cant seem to get the conversion to work to see if the injectors off the smaller motor will work on my app.

The motor I am going to convert is a 32hp,2cylinder motor with a max of 3600rpm. I has a 90mm bore and 78 mm stroke which is the same bore and longer stroke than my 914 porsche. My thought was ,I might be able to use the same injectors that the 914 uses but they have the capability to flow enough for 250 hp and will probably be too big.

sorry to rehash a beat down subject.

The difficulty is that this calculator won't tell you if the engineers picked injectors that were just barely large enough for the motor, or decided to go with much larger ones than necessary. Still, it looks like a small enough difference in power output that the worst case is you may need to bump up your fuel pressure a little bit.

thank's Matt, I have called several places looking for info but have turned up nothing pertaining to this injector.

Do you think the Bosch injectors will work? givin it's the same bore and stroke?

where can I look to try to find a injector for this setup?

what type of fuel pressure will I need to run?

I ran some calcs trying to find a injector for my setup. I was playing with different fuel pressures using the same injecor as my porsche 914.

With 33psi I can get the flow req. for my micro S project. Will this work?
