Bill Jepson Hi Bill, Since the injector is on top of the engine, I doubt it's going to need any significant increase in pressure, since there can't be any real compression at that point. I would think they'd fire the injector while intake air is still rushing in, to help with mixing, so there will likely be a vacuum, rather than pressure. Still love the looks of this engine, and I'm with George, half of one would be nice too :-) Cheers, Rusty (machining my new damper adapter..or cutting off an appendage, too soon to tell) ------=_NextPart_000_001D_01C82AB7.7B88BE00 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Message
