Turbo's lag is basically based on aspect ratio, like if you're using a Aspect ratio of 48 or 61, this tells u about how big exhaust inlet size is, so if its bigger lag will be bigger, gains will be greatest. If turbo is small like 48 or 41, the lag will be less and gains will be low too.
Then comes supercharger, with no lag, ready to fly you straight away. That feel is insane,boost with no lag and that idle sound.
Plus once on my Nissan b11 I was going near rawalpindi pc Hotel, and it was raining heavily and it was chand raat back in 2017. Suddenly my car started jerking, it was a QG18det. Friends towed it to westridge, next day Brought it back to my home. Was diagnosing the issue which made it stopped and found out plugs were wet, dried them and they were again and again getting drenched in water. I said let's open fmic out pipe.
Suddenly saw a flood coming out of fmic, which was a new concept hydrolocking that I found out, so thats what we have from turbo department.currently have ar61 garret turbo with me ready to pull some triple figures soon
