Subject: RE: Which MSD

Gary,
Have you hit the limiter yet? I'm curious how it works. I invented a
limiter back in the 70s that dropped every other cylinder and worked
very smoothly. When you hit limit the engine just wouldn't go any
faster instead of shutting down like most limiters I've seen. I
incorporated this limiter idea in an ignition I did for Indy cars but we
never got it into a race. The engine man didn't like new electronics
and the driver blew the engine by overrevving when he blew a
transmission during time trials. I published the idea and wonder if MSD
picked up on it. Maybe I should have gotten a patent.

Well I unhooked the alternator and ran the radio with the truck on and it
is crystal clear. Problem is I can't find what I need to put in the system
to block it out. Any suggestion on how to eliminate noise from the
alternator?

Ugh! Glad I don't live where you do.

How are you coming with that radio? You have any luck with the buzzing?

Subject: Re: Forever to fill

I don't know if this is the same on a truck, full size bronco, but my
friends BII had the inlet line inside of the breather tube. We simply
pryed open those two little vents furhter than they already were. After
that, enough air was able to get out quick enough so the pump wouldn't shut
off.

>>>>I hate it when that happens!!!
I have the same problem on my '87 F-250 and I go thru it TWICE w/each
fill. I have not noticed a pattern, but sometimes it works just fine,
and others not at all. I though that maybe there was too much fume
build up in the tank, but I don't notice any rushing air while
removing the cap. It must be these Cleveland/NE Ohio stations, I
swear. Of course it happens when I'm in the biggest hurry. I've
tried it w/the nozzle shoved all the way down into the stinkin' tank
itself and even just far enough in to hold the flap open so gas
doesn't spray on me. Nothing seems to work. Here I though I was the
only one suffering....let's start a support group....
Let me know what you come up with,
Randy

Subject: MSD mileage increase





ran out of steam about 3000-3500 rpm. with the MSD it is
engine when you reach the higher revs.

added a K&N filter, just the panel filter. And removed the
cat back. >>

Did you really get a 3-4 MPG improvement with just those changes?? I
would gladly spend the money for an MSD & a K&N if I got even a 2 MPG
increase!
Thanks! Bob

Subject: MSD

Someone asked for a good reason to have a rev limiter on a 4x4 and I have a
great one. Mud and hills. When off roading my friends sometimes zing their
engines pretty good. Floating valves and one guy even cracked a piston just
to get to the top. I dont use MSD but I have a Unilite ignition system and
I am sure that the revlimiter has saved me a bundle in engine repairs while
off roading in the mud.

Hey Casey
I think you are missing the cost/treatment? 1mL treats 1 gal. A quart treats
1000 gal. so you need to do the math figuring an increase in fuel economy of
say 20%. That's 200 gal. saved by using a quart of SUPER 21. If the cost of
fuel is averaged out across the country, you'd find it is about $1.40 gal.
200 times 1.40 is $280. If the retail price of the quart is SUPER 21 is $160,
that is about $120 isn't it? Nearly twice the cost!

So, the tailwind doesn't need to be quite 200 mph!

Besides, a 200 mph tailwind will put you past all the rest stops!!

Kind Regards,
Jeff

Subject: bronco II, modifications

i am new to this ford digest, and i have a question. I am doing a lot of
things to my 84 Bronco II with the small v6. it's not fuel injected, and i
have upgraded it with an offy dual port intake, and a holley 390cfm carb.,
i also unhooked the computer (no emmissions here) and put on a dual point
mallory distributor and mallory promaster coil. i have heard a lot about
cat back exhaust, but i really don't understand what it is. i am going to
get it custom fitted for dual exhaust, but if cat back is good and
relatively inexpensive, that could be an option. But i want it to sound
tough. man it's hard to find performance parts for the 2.8 v6, i got all
these parts at racer walsh, maybe you've heard of it. any helpful comments
or anyone who has done what i'm doing and could steer me in a particular
direction would be greatly appreciated.

Doing the math, the difference in circumference seems to be about 6%.
So John's comment about registering 55 for an actual speed of 58 is
about right. Your gasoline mileage will seem to be less but actually
might be better depending on what the lower numerical "gear ratio" puts
you on your torque curve. If your odometer reads 185,000 and you
changed tires 30,000 miles ago on your now slightly inaccurate odometer,
your actual mileage will be about 183,200 miles. Remember also that for
the same throttle setting, your acceleration will be 6% slower and for
the same brake pedal pressure, stopping distance will be 6% further.
All other things remaining equal, of course.

Subject: Re: Lifts

I bought these coil spring expanders for my Ranger and they don't work too bad
but I don't know if that's good to put that kinda stress on the stock springs.
Any of you think I should just buy a 2 inch lift with new springs? I would
much rather just leave these in because it sure is less expensive and I don't
have all the money in the world.

Subject: horsepower

I have a 1987 351w and would like to get a few more horses out of it. I
have headers but they are pretty trashed. I have a high rev carb $
barrel. and a mild cam. I don't know what kind of horses I am getting
now but I could use a little more to turn my mud Tires on the trails
around me. Any info on some quick horsepower would be greatly
appreciated.

thanks

I have been looking for the horsepower ratings for a stock 1987 HO

I would be grateful.

Sorry, but every now and then I get these brain burps...awhile ago when you
