displacement doesnt matter??
Marley, when's the last time You took a good look at the compressor map of a T3 S60 on Your motor? Versus a Holsten 35?
Displacement is pretty much how You find the VE of a motor. VE kind of matters when You are figuring out wether or not You are facing surging - given Your compressor housing and trim.
You have a GN....

BTW - out of curiousity, what computer are You running with those injectors (sig)?
Disp matters, but when you are going FI,you can shove infinite boost into your engine, and make not as much power as 10psi of boost, because power is dictated soley by the air that can effectively be burnt.
Like how I can shove all the food in the world in my mouth, but Ill only be able to eat a certain part. Just because the food(air) is there, doesnt mean I can eat it(burn it)
For the compressor maps, Ive read many, I dont bother myself studying small turbos. 60trim is too small for my needs.
Holsten 35? Doesnt matter to me who's it is. Ill stick w/ Garett or Precision. John Craig is a genious.(unlike me //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif )
How does disp determine VE? You can have an 100% VE 6.l or a 80% efficient 2.0l
When you FI something, you almost immedialtely attain over 100% VE if VE would be 14.7psi. 100% VE would mean you **** in 100% of the cylinder @14.7psi, and if you are running lets say 13psi, thats almost another entire atmosphere,on top of the pressure of 14.7 as is, thus greatly over the atmospheric pressure of 14.7
Compresor surge is simply the air in the IC piping coming back at the turbo...has NOTHING to do with wheel trim or housing...I would know..Ive had 2 turbos on my car w/ 2 diff housing and wheels,did the same thing. Any car w/out a BOV will get compressor surge,regardless of turbo.
Im running the stock ECU. Running 26psi
