You keep missing the point.........These cheaper systems are NOT designed to do what you are trying to do. WILL they work and get by?.......maybe. Is that what they were intended to do.......NO. They are made for the weekend guy who wants to take his carb off on Saturday and be driving with EFI later in the day.

Lets face........you are building a RACE CAR. Now you may drive it on the street, but it's a RACE CAR. Those guys you are talking about racing with in Huntsville, where you say you need a SOLID 5 sec car.......you may need to reword that to solid MID 5 sec car. A couple of those guys are tickling the 4 sec zone.

This type performance level is NOT what these out of the box, $1200, Throttle Body injected systems are for
