How much reasonable air-flo can an Eaton M90 flow??? 455+ M90=:grin: :grin: :grin: :grin: :grin: :grin: Just a working theory.
The new M120 is only good for somewhere around 350 cubes. The 455 could probably use 2 of them just fine.:bglasses: Even the heavily modded SC3800 guys are 'out-growing' the M90. It's a great supercharger, just a little to small for anything bigger.
I used to own a Thunderbird SC for awhile. Had the M90 sitting on top of it. Nice blower, but as just about everyone said its going to be too small. However, I have seen another Ford guy use 2 of them on a 351 Windsor. It was an interesting setup. James
