| Post subject: | budget EFI ideas + intake manifold heat? |
I am brain storming for my upcoming budget EFI build. Megasquirt II seems like a good deal, and can easily adapt to upgrades in the future ( turbo, Ford EDIS). I am thinking about converting my Carter BBD into a throttle body by adding a TPS, removing the venturi and smoothing everything out. The Doug Dutra article about EFI manifold construction seems very doable. For fuel I was going to use a surge tank primed by the stock pump that feeds the electric pump to the fuel rail. I have access to a small machine shop, so I can fabricate/modify some parts. My question is: with EFI, do I really need the heat riser? Don't I want the intake temps as low as possible, especially if I add a turbo? I am trying to think of some way to thermally insulate the intake from the exhaust, something more than just wiring the heat riser valve in warmed up mode. |

If you are going to make the bbd work as a tbi unit, you would need at least a bit of heat, as the engine still just see a "carburator", even if you can tune it with a laptop. Well, that is my opinion anyway... But there are plenty of guys running around with real carbs without heat. If you are talking about a multipoint injection, with the bbd as a throttle, you won't need heat. uh, forget that part up top...I am getting tired... hard to read words and stuff |
