Actually on gasoline the 160 PPH is what I had to have for injector flow for
my turbo application. (we measured 600 HP at the rear wheels) The N/A motor
uses 80 PPH on gasoline and I figured that alky requires twice the
volume/wf. Consider that my calibration guy wants duty cycles of less than
80%. The turbo calibration was terrible below 3000 RPM because we could not
control very well. An ideal situation would be 2 50 PPH injectors per
bore, run at 70 psig,+boost. I have run at 40psig + boost. With the N/A
engine we are just learning. This is the first race motor that I have not
had a turbo to help things out.
.....More power with alky?? from where other than a couple of percent of
O2..but the ERC has some too for a 'blending agent'...Octane is similar
too..so where might all this power come from..Not that much from the latent
heat thing...
Thats why I asked the question. I need some input from people that have run
both fuels in the same motor.
I have heard a number of statements like yours that there may be no
improvement. Depends on how well we used the ERC fuel we have been running.
Since I have reservations about running 17.5:1 at sea level (dyno and
Maxton) a switch to alky might be in order. I need to have a conversation
with Rick Gold.
Thanks for your thoughts
Keep them coming.
