for a to4e, which setup has less lag, which can make more power, and would they both hold boost to redline?

to4e 57 trim .96 a/r hotside vs the to4e 60 trim .84 hotside.

If i want >350hp and as little lag as possible which setup would be better for me?

Ive searched and that narrowed my decision to these two setups or the to4e 60trim with the .96 hotside but that setup is only if these 2 choices dont get me deccently past 350hp

Turbine A/R dictates power band.
Compressor size dictates power potential.
...as a rule of thumb.


The one with the smaller turbine A/R - "60" 0.84 A/R.


"60", but the power output between both will be close...I'd say within 50hp of each other.

Different people have different views of what "hold boost to redline" means.
This is more dependent on the WG set-up.
An EBC makes this matter moot.
The larger turbine A/R will tend to not drop off at redline - "57" 0.96 A/R.

I don't think the "57" will be able to hit 350 at the wheels.
The "60" should be able to hit 400.
If you insist on hitting over 350 at the wheels, then the "60" is your only choice.
