So you know what the possible horspower is at that PSI? This won't tell you how bad it lags though right? Another questions does the stage 2 and 3 Ludespeed Turbo T3/T4 have as many CFm's as a small 16G DSM? These turbo's look smaller than the T3/T4 but produce lots of power.

According to the chart I took that from, 1.45 CFM approx. equals 1hp. There are many different sizes of t3/t4's. You would need to find the specs for whatever trim ludespeed uses to see how it compares with a 16g.

a svx motor with boost is not a good idea! You well make a bit more power for a very short time!
