I would have to put my money on the Profec. I have worked with and built
stepping moters before, and with the application of fuzzy logic technology
the boost controller can find the quickest "route" to achieving the desired
boost level without overshooting that boost level (thats the key). Also
mantain that boost level once it is achieved. The "parameters" that need to
be "characterized" by the controller are the desired boost level, the rate
at which boost climbs, and how well the wastegate bleeds boost pressure. If
you chould quantify these "parameters" you could build or tune the ideal
controller, unfortunately everyone has a different setup. This is were
fuzzy logic comes into play. The idea is to keep the wastegate closed as
long as possible, but not to open it too late as overboost occurs, and to
complicate matters you have the rate at which the "gate" opens. Now how the
controller opens the "gate" will depend on the wastegate characteristics,
and how fast boost levels climb, and the desired boost. I hope you can
"see" that. I feel like I am not making any sense, or perhaps confusing
matters worse.
As for the injectors, I have not installed them as I have not ordered the
MAF sensor. I put that off, because my clutch was slipping too bad, so I
put my money on a new clutch. Now I am a little frustrated, because I have
Texas Probe Summit on June the 12th, and my Clutchmasters Carbon/Kevlar
Stage III clutch is on the way, but no Aluminum flywheel. I talked with ELP
Motorsports about buying an Aluminum flywheel last Friday, and they said
they would get back with me that day. Here it is a week later, and I have
left 2-3 messages a day for them to call me back, and I still have not
answer. The have told me in multiple emails, and over the phone a couple of
times that they can make flywheels for our application, but now that I need
one I cant get a hold of them. I would like to have the two installed and
broken in by the event but it just doesn't look like its going to happen
thanks to ELP.
I will be RE-installing a working Walbro fuel pump this weekend, and will
probably cut an order for the MAF in a few weeks, so I can get the fuel
system fully upgraded for force induction. I will keep you updated.
Thank you for the dimensions,
Enjoy,
Bryan Pendleton
