speed density?

For a 5.0 Mustang(stock engine) single set-up, with this turbo:

Master Power 60-1 "P" Trim - 630hp
TO4 ' P ' Trim Turbine wheel - 64.5mm / 78mm
Super 70 Compressor wheel - 60.5mm / 84mm
.70a/r Compressor housing
T4 .68 a/r housing

Could speed density work or would I have to switch to mass-air?

Thanks
Fred

Re:speed density?

You could do either...

It's like saying, Carburators or Fuel Injection...which works?

Re:speed density?

i dont know much about speed density but i would assume mass air would be better (before the turbo, im not sure if a ford maf/mas can work under pressure)

I'm a fan of speed density, ---- putting restrictions in the intake.

can I get by with just getting bigger injectors and a bigger fuel pump? How do you trick the speed density system to tell it there is no boost?

What is one that would work on a 5.0 mustang? I have read that you can use a check valve and an fmu, but all the people around here are saying that the car will not run...

I dunno

Thanks for the replies!

Re:speed density?

All aftermarket engine management systems do speed density, except a few that are designed for specific applications.
Price ranges from about $150 (MegaSquirt) to about $2000 (Autronic, Pectel)
