67 is bigger on the turbine side. In terms of flow on the compressor it is not.I'm not sure if you would call a 67 a "bigger" turbo... but my car makes near peak whp from 4500-6500.
There is no way in hell you make 150 to 200whp more than me, fyi.
That's a lot...
over 20 psi of boost my 30R hotside combined with only .64 a/r housing is highly restrictive. But I can still make big HP/torque at lower RPM making up for the losses at higher RPM.
There is a 6262 Turbo going in the parts car today. That will wake it up big time and put the trans to bed lol
