Around the 400 whp realm, would the .70 AR on a 62 sxe have any drawbacks (pick a scenario) compared to the same turbo with a .83 AR?

RC did your 62 have lower egts up top with the tighter hot side because it boosted sooner?

With a ve, absolutely no drawbacks. The turbine flows a ton, and the gate is always there just in case. If you had the airflow mods that bc847 has the.8 is more logical, but at this point none of us have airflow like David.

Thanks Dman. It's impressive what the sxe's are capable of

They are some pretty awesome little chargers, especially for the price.
