First off,
Happy New Year DML.
Tony,
Agreed 100%! The 318 was very well engineered from the factory as an MPI
motor. The factory TB was well thought out for this motor. The 360 got the
exact same TB, which was a compromise to save $$. The 318 is "well aired"
in a stock or very light mod situation with the factory or ported factory
TB. (around 650-740CFM @ 25") The 360 likes to start out (stock) at
around 720CFM and go up from there as the modifications continue!
Installing a TB that is too large for your application is not good practice
and usually costs you in the launch and 60ft times. Our 52mm TB flows over
860CFM, which is too large for a mildly modified 318! It will work, but it
wont be optimum! With a stiff cam, good fuel mapping and some head work
(and the other mods that go along with that), it could be the right choice!
F&B has 5 different sized TBs for the Magnum V8/V6 motors so a perfect fit
is possible. I appreciate all the good things said about us (F&B) and we
will continue to work to provide the best solutions to the problem of going
faster (in style!)...
Thanks!
Bruce
