The other smaller stuff will create a lot of exhaust backpressure, and egts will skyrocket in the higher rpms. I have done it before, if I remember correctly was near 1800 deg F past 6200rpms. Was 400rwhp @ 16.5psi on something extremely close to a GT3076R.. |
from what i understand the .84 a/r would spool faster than the 1.0 a/r. i'm just curious if the .84 a/r would be too small and cause excessive backpressure and heat.
smaller a/r should just shift the powerband down. i would rather take under the curve power over top end power. for the modest (if 400hp is modest) i'm after i doubt the falling off effect would really come into play with the smaller turbo. |
