STEVO, I hope you're reading this homeboy! 14psi!
I just apply the formulas...I'm still not a turbo master...I can be wrong...but I think my numbers are making sense and their based on solid numbers. I think would be better first to target more the 300+ than the 400
But what you have to know...is I calculated 14 PSIg with an average setup. When I optimize everything it seems possible to reach 400 HP with 8 PSI....but with
100F Tm = Intake Manifold Temperature (instead of 130F )
0.99 VE = Engine Volumetric Efficiency (instead of 0.98 )
0.5 BSFC = Brake Specific Fuel Consumption (instead of 0.55 )
11.7 A/F Ratio (instead of 12.7)
it gives ...
400hp@6200
Wa = Airflowactual (lb/min) = 39
Pressure Ratio = 2,8688776
The VE is theoric I don't know the true value for the 3MZ.
To reach 100F intake manifold temp you would need a pretty efficient IC.
THE BSFC is also theoric, I don't know the real data...but I optimize it with the range Garrett are using. The A/F is rich and the setup will need good upgrades regarding fuel system to reach it.
But it can be made...but I guess the stress it will gives to the 3MZ can damage at least the rods. I hope your cousin is serious and preparing himself with good research and numbers to validate if the intermals can make it thru.
