100% VE: 2500-17.727 3000-21.273 3500-24.818 4000-28.364 4500-31.909 5000-35.455 5500-39.000
at 85%: 2500-15.068 3000-18.082 3500-21.096 4000-24.109 4500-27.123 5000-30.137 5500-33.150 But also keep in mind that this is not m^3/min rather lbs/min. m^3/min at 100% VE with 6psi you'd be at: 2500-10.768 3000-12.922 3500-15.075 4000-17.229 4500-19.383 5000-21.536 5500-23.690
85% VE you'd be at: 2500-9.153 3000-10.984 3500-12.814 4000-14.645 4500-16.475 5000-18.306 5500-20.136
As you can see, on 2 psi, 4 psi, you'd be spooling the turbo by 2,500 K but these numbers don't take compression ratio into account. I also used a temp of 85º which can and will change. It aslo looks as if a 2.0 Pr and around 8-9 M^3/min would be somewhere in the middle of the *island*. It takes roughly 150 cfm to make 100 hp so in order to make say 300 hp you'd need roughly 450 cfm. 9 M^3/min would put you in the 320cfm catagory but this turbo would be capable of 17.5 M^3/min max. Any way you look at it, you've got alot of math to do before you even start welding  lol
What are your HP/Tq goals for this motor/ I think missed that? |
As you know, stock is 200 hp, 275 lb/ft. With the bolt-ons that I have now, I am guessing my engine is pushing around 250, as *gasp* a G-meter that I have was rolling up 202 hp to the front wheels. With the turbocharger, I would like to add another 80 or so hp. That would be considering that I remove all bolt-ons, return to stock values, and add the 80 hp to that.
As for the torque goals, 80 would be good too, however it may happen to work out.
As for the math, I'll leave that up to you
I am barely passing College Algebra and cannot stand another polynomial to the tenth degree...If you understand what I mean...
So if we can translate the jargon you've just jotted down (sorry for that term, but I hate math), the turbo should start to spool at 2500 RPM's?
