[QUOTE="TyCorr, post: 1435323, member: 1451"] Yea. Cranking it shut is fine on an 80 or 100 percent nozzle. But a bigger nozzle will blow that ***ker open if you pour the hot, hot coals to it. If you try to do that on mine it'll start blowing through the gate at 28psi. If adjusted it'll make about 32psi in lighter tunes but in the hotter ones despite the gate opening it'll creep up to about 36psi yet the gate is still keeping bp in check. I drilled my turbine hsg so it pulls from both volutes. My back pressure is 1:1 until 30 psi. But i also dont have egt issues. Well besides finding gauges that arent garbage. If some of you guys are using autometers you might not even have high egts but the gauge is saying you do. I did some searches and as I have been saying for the last five years their quality control and such is so bad that tons of people are wondering how they have 600 degree egts at ***kin idle. Mine you could wiggle the wires on the gauge and it'd go from 500 to 275 at idle. I can see less gands on owners being confused and assuming their egts are 1200 degrees at 65mph. [/QUOTE]
