Twin Turbo Size Calculator
Twin Turbo Size Calculator. With great power comes great irresponsibility please note that this calculator should be considered a fun tool and cannot be. Displacement (liters) (122.04 cid) ambient air temp (deg f) altitude (ft above sea level) (14.502 psi.
Cfm = cubic feet per minute. Common wastegate selections for applications are: A larger bore in the housing will typically yield more power.
This Gt2871R Map Indicates That A Pressure Ratio Of 3 Will Deliver 400Hp.
P2c = 40.48 + 1 psi. Where, wa = airflowactual (lb/min) hp = horsepower target (flywheel) a/f = air/fuel ratio bsfc/60 = brake specific fuel consumption (lb/. Enter displacement, efficiency, maximum engine speed, maximum boost.
Cfm = Cubic Feet Per Minute.
With the same goal of 650 whp the owner hits the dyno and is able to make 650 whp on pump. You cannot make more horsepower that your turbocharger can supply.for instance if your turbo peaks at 360 horsepower (about 44 pounds per minute) it simply is not going to make any. The pressure ratio is simply the proposed absolute outlet pressure.
This Online Calculator Should Be Used As A Tool Only.
Enter the capacity in cc, together with the rpm that peak power will occur at. 2.0l or 2.3 4 cylinder t67, gt40r, gt42r. Recall from turbo tech 103:
These Turbo’s Are All Rated At 80+ Lbs/Min Of Airflow And Will Flow Enough To Make 800+ Wheel Hp.
Turbo size calculator peak horsepower air fuel ratio typically 12:1. Use this calculator to determine the turbocharger requirements that best fits your setup. The trick is keeping the turbine wheel's diameter within 15 percent of the compressor wheel's, give or take.
Overspeed And Damage Can Result From Many Variables.
Determining an engine's boost pressure ratio is the easy part, but it requires a reality check. P2c= mapreq + pressure loss between turbo and intake manifold compressor discharge pressure drop = mapreq + delta p loss assuming a 1 psi loss: Target crank hp # of turbos1 1 2 engine displacement liters # of valves/cylinder2 max hp rpm3.
