damn, so my aaz camplate and 10mm head is deemed to be a failure right from the start? hehe
I'm still extremely sceptical of the concept of getting 60HP by just changing the pump and welcome the discussion of ideas. We all reserve the right to disagree
guess not....goes back to understanding how the pump works...and your description was great.Joe
If the governor starts limiting fuel at under 4000rpm then why can I blow smoke at 4500rpm? It pulls fairly hard still and the smoke is slightly less than at say.... 3500rpm. Shouldn't the fuel be so limited that it couldn't smoke? This is a with a 1.6NA.
Don't forget, even with falling fuel delivery, the HP still increases with RPM rise to the peak HP point. Much more so and beyond with a Giles pump!
I'm sure someone will correct me if I'm wrong but it may be because the fuel is not being injected early enough into the cylinders to allow enough time for a complete burn so you are getting wasted/semi-combusted fuel out the back (black smoke)
