[QUOTE="V-Ref, post: 22456, member: 660"] To your original post though...at 24 psi of what AE calls "Manifold Guage Pressure", AE data logs 38 psi of "Exhaust Back Pressure". I'll see if I can't post some better data logs later today. PTE 76mm billet inducer (not sure on exducer), Dual ceramic BB air cooled center section, 75/83 compressor wheel, .81 undivided T4 compressor housing. 200% nozzles. Turbo needs 800 deg, 2100+ rpm, and then it "lights". Hard to see/log anything in the 20-40 psi boost range....kind of on/off situation. [/QUOTE]
