dose any one use blow through carbs at all? i the mustang I'm looking at is a 87 that is speed density right? Ive heard that SD is not that good for a turbo application. is this true? so I'm guessing in the the mustang world no one really does the fmu and msd btm method? seems that there are better choices any ways. i appreciate all the info guys ill have to look into all of those.
87 speed density computer can not be tuned by above listed tuners.
Its a quirk for that year. All other years are MAF based systems so that is what
got aftermarket development.
SD is actually better for boosted motors, but again no one put out an
aftermarket tuner for that one year they used it.
You can do a MAF computer swap, do a search tons of threads and info.
boost-a-pump and FMU are very limiting and dont give a very safe tune.
Boosted motors need more fuel than an N/A motor. They run at much richer
a/f's at WOT. To do it right you really need a custom tune with the fuel and
timing maps adjusted properly.
CSU makes good blow-thru carbs if you want to go that route.
