New affordable Fuel Injection

The OEM electronic specs are usually over 100c (212F) for pretty much every electronic piece. So, if all the components are auto related, it should last no problem assuming the components are good quality. I'd be more worried about the vibration being engine mounted personally over the heat.

I have a sequential multiport setup on my car with coil near plug, and that is really incredible. These cheaper TBI setups certainly decrease difficulty, however, you'll remember that you're giving up some potential here. Really depends on what you are going for. I won't have to worry about "wall wetting", the design of the intake for wet flow, or a distributor cap ever again, but then again it cost a lot more. really, really fabulous compared to a carb. 45 degrees ambient and it fires and drives perfectly immediately. I can fix any fueling problem in a matter of seconds, and I can easily see everything the engine is doing.

Hi. My name is Larry and I live relatively close by (Garden City). I ran a dyno at the Ford Scientific / Research lab 17+ years before moving into vehicle development. I'm in agreement 100% with your findings. The only TBI unit I was considering was the FAST unit used in many of the Roush crate offerings. Having been involved with engine development, I have seen the clear advantages of a multi-point sequential system. It completely eliminates the atomization / wall wetting problems created with introducing the atomized mixture far upstream from the valve. The ordinary guy doesn't realize that when the air (light weight) and fuel (heavier), traveling at speed together, don't make turns or bends at the same rate. The air is easily directed while the fuel can't make the turn as quickly and hits the walls of the manifold. That's why the single plane manifolds have better distibution. Straight shot...less turns. Enough school. Let me know the make/brand of the EFI system you've got. I'm really interested. Thanks.
