keep us posted on what he does and recommends, and how it turns out, and the diff. before and after. may be a huge learning tool to the rest of us fast owners !!
The Roadrunner has been a really disorganized build. Maybe I shouldn't even refer to it as a build project. It'd probably be more accurate to describe it as a car that we've been throwing parts at in an attempt to increase power. There are so many things about it that we should know but don't. We didn't build the motor and the guy Spencer bought it from didn't know any of the engine specs. We don't know cam profile, compression, or how much it's been bored.
I felt like an idiot when we took the car in and they started asking us questions about it. Adding the headers was a no brainer in an attempt to increase exhaust flow. We threw the heads on it as an afterthought simply because we had them around and had no other place to use them. We never considered the effect on compression ratio and have tried to guess at what we have based upon some calculations my son made. We're thinking it's around 9.5 to 1.
I don't know how many details we'll get from the shop when we pick up the car. I'll try to document everything I can. When I post on this thread it's partially so we have a timeline of changes that we can go back to ourselves to see what we've done and when we've done them. I know from reading other forums that others have been having tuning issues with their FAST systems. I doubt that we'll be able to provide a definitive guide but we'll give as much info as we can.
