Very Nice.
My FMU keeps the fuel pressure up for quite a while after the car has seen boost. I was going to ask about this (start a thread) but I think i figured it out... After the car has been shut off the FP returns to normal. I think either the FMU or the 'one way check valve' keeps the FMU in a 'multiply the FP by the FMU's set RATIO state' on purpose. It the FMU fluctuated on and off immediatly upon going from boost to vacuum and back again (during manual shift for instance) this could cause intermitant FP problems. That might be bad (rich to lean then rich again, etc...)
Maybe some veterans can tell us about the 'fmu sustains FP well after engine is no longer seeing boost' deal. ?????(anybody????)
You have a used kit with a BOV so MAYBE you have a modified or adjusted FMU ratio. Instead of the FMU multiplying FP by 6/1 perhaps it is running 3/1 or 4/1. Your FMU is working it seems...but you are seeing a lot less FP increase than on my rig for instance. (my FP is 47-51 at idle and up to 86 psi at 6 pounds of boost.)
Are you seeing FULL RICH on your A/F gauge when you are 'dropping the hammer?' You want to figure out if your max '65 psi FP' under full boost is enough to keep the Air Fuel Mixture on the RICH SIDE. Did the guy who sold you the kit say anything about the FMU? Can you contact him...ask if it has been adjusted? Is it the 'stock' vortech fmu that comes with the RKSPort kit or did he replace it or change/modify it?
Dont worry about leaks in fuel line. the most important thing is to worry about good fuel line connections when you do things line adding the FP sender and the FMU. As long as those are ok the rest of the system is very capable of handling the hi psi of our high pressure fuel system.
Um, I can't help much with the slow launch problem. I haven't had to worry about that so have never studied it. Was your AC on when you got the slow launch? Have you tried launching with the AC off? (sometimes having the AC on can cause bad idle...bad idle can cause bad launch)
So, how loose/tight was the belt before and after your cool 'quick grip clamp' job?
