We spin out with 35" old style BFGs 4:10s and a 2.5 inducer S400 in 4 low 4th. We used to snuff out at the end when we had a fueling issue. 5x18 injectors are not enough for that turbo pulling IMO. 5x18s were not enough for us. We run 5x22 JL injectors now on our 2.5 and that is about perfect for our setup. Run too small of an injector and heat will be an issue. Ours cooled way down and quit snuffing. Carries 80 psi until we let out. A tight housing on a small turbine isn't the best setup in itself.
