I am looking at doing a turbo upgrade, and i am going to want quite a bit of hp. I was lookin at the T66 and that flows 65lb/min and the GT35R goes 65lbs/min...i was just wondering what the stock VF34 flows, and what the VF22 flows, or maybe you can point me in the direction of a website that can give me the flow ratings.
thankyou

 

 

Here a map for you...






edit: These are all the IHI turbo's.

60-1 ----------------- 725 CFM at 14.7 PSI
GT-35R -------------- 820 CFM at 14.7 PSI
T72 ------------------ 920 CFM at 14.7 PSI <--- Note you would have to spin a 2.0 L engine at about 14,000 rpm to flow this much air.

IHI VF 25 ----------- 395 CFM at 18 PSI <--- estimated
IHI VF 26 ----------- 400 CFM at 18 PSI <--- estimated
T3 60 trim ---------- 410 CFM at 20 PSI
IHI VF 27 ----------- 420 CFM at 18 PSI <--- estimated

PE1818 ------------ 515 CFM at 22 PSI <--- estimated from manufactures rated max power
Large 16G --------- 520 CFM at 22 PSI <--- upgraded flow some on review of compressor map

========= 526 CFM max flow for a 2 Liter at .85 VE pressure ratio 2.5 (22 PSI) 7000 rpm =======

========= 578 CFM max flow for a 2.2 Liter at .85 VE pressure ratio 2.5 (22 PSI) 7000 rpm =======

HKS GT2835 ------- 580 CFM at 22 PSI 400 hp
MRT 400 ------------ 580 CFM at 16 PSI
AVO 400HP -------- 580 CFM at 17.5 PSI
MRT 450 ------------ 650 CFM at 19 PSI
AVO 450HP -------- 650 CFM at 20.0 PSI
SR 40 ---------------- 650 CFM at 22 PSI

========= 658 CFM max flow for a 2.5 Liter at .85 VE pressure ratio 2.5 (22 PSI) 7000 rpm =======

HKS GT3037 ------ 670 CFM at 22 PSI 460 hp
PE 1820 ----------- 680 CFM at 22 PSI <--- estimated from manufactures rated max power
20G ---------------- 695 CFM at 20.0 PSI

HKS GT3240 ----- 830 CFM at 22 PSI 570 hp
GT-35R ----------- 880 CFM at 22 PSI
T72 --------------- 1000 CFM at 22 PSI <--- note you would have to run a 2.0 L engine at >40 PSI boost to flow this much air

Conversions used where I had control over conversion factors:
1 HP approx equals 1.45 CFM

1 CFM approx equals 0.0745 lb of air/min

0.108 Lb/min approx equals 1 hp

1 Meter cubed/sec = 35.314 CFS = 2118.867 CFM

1 KG/sec = 132 lbs/min approx equals 1771.812 CFM

power coversions:
1 PS = 0.9859 HP = 75 Kgf m/sec
1.3405 HP = 1 KW
1 HP = 746 watts

 

Perhaps this will help

 

Thats what we're here for. We're the guys who make those turbos spool faster
