Heres an overlay of my 5.3 turbo vs the brand new GTX ball bearing style turbo "fast spooler" on an SR20DET at 30psi
It is a deceivingly fast spooler. Next time I hit the dyno I'll grab a 2nd gear to 3rd gear pass so you can see just how fast it really spools.
Actually If just watch my videos you can see everytime I nail it on the downshift it rips the MPH gauge
None of these are 3rd gear pulls, it downshifts automatically to 2nd. there is no "lag" lmao
