Changed up the turbo build a bit and will be running a 90mm LS2 intake. I have a 85mm TB now would I see any benefit upgrading to the 90/92 mm TB. Setup in sig.

What size is your charge pipe? I wouldn't think having a TB that's bigger/flows more than your charge pipe would be beneficial, but I'm no geologist.

Isn't it not worth that many whp in an NA application? I should think it would be worth less with a hair dryer forcing air through it... Sure, on a max effort motor every little bit counts and more air is more air, but the $ vs whp ratio isn't good... I'm no expert though.

Its worth more to slow the air down entering the plenum more than anything
