Kenne Bell on the 5.0??

MY 85 GT said:

Thanks for taking time to help me out.....I do have a couple more questions please...One what wiring needs to be hooked up? Where does the vac line go for the boost gauge..lol like thats important right now... And for now could i run the FMU and say throw in some 24 pound injectors and a MAF sensor to match will it be ok until i took it to get dyno tuned...And im sure the stock pump would be ok for now with the FMU? The reason im asking this is i want to save myself money by doing the install myself and be able to save up for a good tune later on...Would i be able to say bolt this on and drive it with say the FMU and be ok?...Oh yeah how about timing? what do you do about that less intial and less total?...Thanks again I know how to set intial on the car how about total cant do that right? without a tuner?

Going based on what my set up consisted of (and again, I’m running a different kit), most of the wiring consisted of the Kenne Bell Boost-a-pump (which I think the 5.0L Kit comes with) some ignition related stuff and some extension wires for the ACT sensor. There should be a spot on the Supercharger manifold casted for a line hook up to the boost gauge. It will detail all of this in the instructions. Now that I think about it, you may need to bend your A/C lines a little as well, but I don't recall it being a major issue.

The FMU is designed to work with your current 19lb/hr injectors. I jumps fuel pressure from he stock 40lb/hr to probably about 70lb/hr under boost. Adding 24lb/hr units to the mix without making changes to the ECU program could result in drivability issues. Some guys have done it without issue, others have all sorts of problems. Since you're sticking with the stock head and lower intake components, jumping to 24lb/hr units aren't necessary right now anyway. If memory serves, the FMU increases injector flow to 24lb/hr anyway. I'm pretty sure KB also supplies a larger in tank fuel pump, or the aforementioned Boost-a-pump to increase fuel flow to the injectors. You'll have to ask them specifically, as this may change with each kit.

If you're going to swap out injectors and go with a chip dyno tune later on, I would go with nothing short of a set of 36lb/hr units. This will leave you a little more room to grow should you start upgrading heads or modifying your lower intake in the future. Having an injector that flows a more fuel is better than having one the won't flow enough. Besides, you car still utilizes a "return style" fuel system, so whatever fuel is not needed is recirculated back into the tank.

I'm not sure what KB does for the timing set up. If I recall, you start with the factory 10* setting and a timing retard device is supplied to pull timing on the top end. Again, this will be covered in the instructions.
