Modding... My Jeep

**Doctor Feelgood** · Posted: Sat, 11 Oct 2003 11:51:25 Post Subject: Modding... My Jeep

No PC work this morning... Tweaked my Jeep Cherokee's 4.0L Inline 6 Cylinder instead...

1. Rusty's Off Road Air Tube with K&N Air Filter
2. Rusty's Throttle Body Spacer
3. Platinum Plugs
4. Heavier ignition wires
5. New distributor cap

Maybe I'll get this 190 HP stock up over 200... Sun

Should be good for 10HP depending on how bad the stock intake setup was.

What wires did you get? Were they precut? What plugs (don't say Bosch please)?

Well... the throttle body spacer has already been removed... it made this really annoying whistle with the gas pedal about 1/3 of the way down. Not cool for a daily driver. It has a helical bore I may have machined out to be smooth, but we'll see.

The ignition wires were all pre-cut... The inline 6 on the Jeep requires 3 different sizes to make it fit / look decent, and to be honest, I don't even see a brand name on them or in the catalog. They are much beefier than the stock wires, and even if its all in the insulation, the quality seems higher.

The plugs are Auto-Lite Double Platinum. They seem good, but I didn't really care to research them too far...

You let a little whistle get you down? Laughing

After I removed the Holly and the aluminum spacer on the Bronco to do some grinding and polishing, it whistles at a certain spot when you just crack the throttle open. I rarely hear it because the spot it whistles at isn't a spot that you use too often.

I really don't know why it started that, because I enlarged the bores in the spacer to match the carb, polished them to a 2000 grit finish, the polished the bores of the carb (just had some dings on the bottom from being taken on and off over the years), and ground the screws that hold the butterflies down flush.

I think it's the screws doing it, I probably didn't get one quite flush and it has a gap that air goes through...

Anyway, did you call the manufacturer and ask them if that was normal? Might be some way to make it stop.

I had the throttle body spacer machined to remove the helical bore, and re-installed it this morning!! w00t! Whistling gone, punch is back... all is good. I'll just have to keep an eye on my gas mileage to make sure its worth it...

Cost:

Machining the throttle body spacer... 1 bottle of Cherry Brandy.
Eliminating the whistling noise... PRICELESS!

what does "HP" measure?

Spire · Posted: Sun, 16 Nov 2003 23:27:47 Post Subject:

HP = HorsePower

Horsepower is defined as work done over time. The exact definition of one horsepower is 33,000 lb.ft./minute. Put another way, if you were to lift 33,000 pounds one foot over a period of one minute, you would have expended one horsepower.

That clear things up???

And welcome to Big Bruin!!!!!
