smokinrod said:60psi , it's a wew bit laggy but when it hits ,it is scray bad. it is makin some goood HP . I was in High range 4x4 ,strated spoolin it up got to 18psi and the turbo lit and instantly snapped the output shaft on the 47RH
you'll have to waite to see it run untill the DHRA Martin MI event,
I'll be there with it and were putting on a 2 stage NOS kit for that. it should be kinda neat a sled puller with NOS and slicks.
