From CB Performance It is a 7161 dual diaphram pressure regulator cost is
79.95. I needed it to deliver fuel to the cylinders at a faster rate. I
determined that the fuel was not getting to the cylinders fast enough. The
engine made good power to 4000 rpms then dropped off, if I let it stay at
4000 rpms then accelerated, it would have power. I installed it with no
changes and the mpg went up @2mpg and the power also increased.

I talked to them several times for a long periods of time. I told them that
I wanted a cam slightly larger than a stock cam BUT not too large. The
problem was with the stock FI system.
We decided that the "91" grind on both intake and exhaust would be the best
choice- small increase in duration @6 degrees with a increase of lift from
.333 to .363.
I also planned to run 1.25 ratio rockers.
The use of the ratio rockers helped to increase bottom end torque to offset
the loss of torque by changing the duration and allow for more breathing at
highter rpms. With a change in duration, the power band moves up the rpm
range. Plus the lifters and valve train do not have to travel as far to
obtain the additional lift increase, so reciprocal weight does not increase
as much as with just going to a larger lift. Less were on cam lobes due to
not as steep ramps. Valve is also let down "gentler" do to not having the
ramps steeper
Will it pass smog? (I'm in Ca.)
I had it smogged before I put on the new AFM and it was .03% and 33 out of
220max.

I agree...
There's a place here in santa ana thats putting the

I put big valves into my 1641 dual port T1 engine and went from @40mpg to
getting 20mpg.
It's fastgermanauto.com if your interested.
CB Performance has some of the same hop up parts for less $$
Are you currently building an engine or have you already built one?
