You can ignore what we are saying all you like. Trust me I know what the banshee does, I have talked to steed he is a very smart dude. His tuning does not use shaft speed to tune the turbo, only a gauge. I have a 351ve that I have controlled using, boost | boost and drive | drive | tps boost drive | tps rpm boost drive | and finally shaft speed , tps, rpm. There's a reason why I have written about 50 different base tunes for the turbo, you need to know shaft speed as a calibration part of the tune, if you don't know shaft speed you overdrive the turbo across most of the map and you have EGT issues. vane position at 15 psi and 70,000 rpm != 15psi at 120,000 rpm.
I am not going to argue about spool speed...
The point is if you overdrive the turbo you run into high EGT issues, which you have. Right now I have a 351ve with 7 x .009's at 7000' altitude and I can't break 1200*f. so if you are having EGT issues with 451 then your issue is not with the turbo, rather the tuning of the turbo....... You have more than enough fuel now to get the 451 into a happy part of it's map.
so yes it is very much a tuning question. So to answer your question yes the 451 can handle those injectors, IF YOUR TUNING DOESN'T OVERDRIVE THE TURBO. the 451 will flow ~80 lb /min
FYI I have been in a truck with a steed controller and I know EXACTLY what you are talking about with EGT issues. You should not be having EGT issues with your setup
His setup is really cool and he is a very bright dude, but I really wish he would use shaft speed to tune with.
