Subject: '7730 and nitromethane

I am currently in the process of building a 377ci. SBC designed for =
bracket drag racing, and I am very interested in using a 93 oct. pump =
gas/15% nitromethane mix ratio for fuel. I know that one of the benefits =
of using nitro with gasoline is increased octane characteristics, =
including adding an oxygenate to the fuel, but I'm rather ignorant of =
the many other pro's and con's of using it. Engine management will be =
provided by a '7730 ecm and related harness. I wonder if the Bosch =
injectors will be compatible with such a fuel, in terms of sizing and =
magnetic winding tolerance to the fuel. I understand that due to the =
oxygen content of nitro,=20
(49.6% by weight) that more fuel will have to be administered/ms of =
pulse width than with conventional gasoline.

Does anyone have any contributable thoughts on this idea that may steer =
me in the right direction, or maybe know of some publication that =
explains the use of nitro as an auto fuel? Thanks in advance and looking =
forward to your comments.

Regards....
