everyone goes big and doesn't push the turbo at all. not nearly to where its designed too. trade off? lag.
the vortec turbo truck community is most guilty of this. a t100 turbo, 6" thick ic, and 6psi boost. like, why?

Bs. As long as you have a properly setup boost controller that can keep the wastegate shut until you are approaching peak boost if anything a higher boost will be laggier as it takes longer to build to peak

an oversized turbo at low psi will build boost slower than a proper sized turbo pretty much maxxed out.
the wastegate staying closed won't magically make it spool faster. rotaries like to blow internal wastegates open from exhaust pressure if they don't have a helper spring or adjustable actuator.
a boost controller just helps if the wastegate is sized right in the firstplace. rolling antilag, 2step, nitrous, etc is what makes the lagfest bigturbo spool faster.

same cfm but higher psi is more stress than low psi for the same cfm. that's why. so less money and work into the build of the motor. and a bit less likelyhood of it going pop when tuning. downside is small powerband. going water to air intercooler would help reduce lag with the short pipes and less intercooler core to fill up and less pressure drop. but again work and money.
the boost controller will only help the turbo spool faster going from having the wastegate read straight manifold pressure to using a boost controller. does the same thing as using helper springs or and adjustable wastegate to an extent. but much easier to set at a specific psi with the fastest spool

>6psi
what kinda spring you running in that wg, nancy? put the right spring in there and you wont even need a boost controller.

Thinking of strapping a centrifugal supercharger to my shitbox but they don't really seem much cheaper than a Whipple. What do?
