The Story (or original problem):
All after-market 6 cylinder Ford 4.1 litre inlet manifolds
don't have good, or even, or efficient flow on all six ports.
There is up to or 80% variation on all other after-market manifolds.
We set about to fix this ( N Moxey & D. Jones) and came up with a manifold that works & has even,
efficient flow to all ports with only approximately 2% variation.
Using the right
carburettor (500 Holley) and a good D R Jones Head, we gained over 200 HP. |
