Yeah, wish I could spin it alot harder becuase it would pick up alot more. I am only doing 52psi max total psi and only producing about 25psi out of the big turbo. I wish I had a back to back with the cast because that was huge down low increase, like 200hp/400ftlb increase at 1700rpms. I was never really happy with how my twins ran with the cast 475/96 becuase it was extremely laggy compared to the single turbo that I was running previously. Topend was fine with the twins just sucked driving around town and coming up on boost. The billet wheels in the atmosphere turbo made a huge difference in drivability so it is pretty much all I sell now. It is definitely marketing at its best and I can't blame them for it, there will be alot of used like new turbos flooding the forsale market very soon. I will probably not go this route with my billet wheels that I had them make for my vgt and lb7 turbos, and offer them to any one that has a 4094 based turbo. Thanks again Bullseye for the great products, most of my customers are running Bullseye based turbos! They won six different points championships in sled pulling in 4 states so we must be doing something right.:charger:
