Was reading the thread about high horsepower trucks with stock turbo. Didn't want to hijack that thread, but wondered what the difference would be with a 351
what sort of numbers are people seeing with a turbo upgrade from the stock 341 to a 351 off of an 04.5 and up truck? Especially on an otherwise stock truck.

Thanks
Bryan

Just turbo alone about 40hp. The 341 moves about 43lbs of air and the 351 moves about 60lbs. The down side is the turbine housing is still only 9cm but the wheel is 2mm bigger.
