This is a NIB turbine that I just started today in a new Cermark Viper, popped and started as normal first time. It is in a BVM pegasus fully enclosed bypass NOT the factory Cermark one.

My question is what can most likely be causing a very slow spool response on throttle? like 5-6 seconds lo-high
I operate another non SP pegasus in a Kingcat, and it is typical 3-4 second spool.


EGT running 571-635.

Here my list, but what is higher probability.

Bypass starving for air. has some cool sounding whistles at variuos settings
Slow heat seen by Temp probe, maybe put it further in cone?
UAT is notcably sucking in sides, I kept all lines to 5/32" ID.
Pump was not broke in seems a bit high @ 5.6-60Vout on display.
Lines on fuel supply are same as Kingcat so not thinkin this.


Any help would be greatly appreciated.............
