      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Glass-pack mufflers

Recommended Posts

Dual-piped my truck this past summer.. The guy who did the job for me put a glass-pack muffler in so it wasn't extremely loud.

It's fairly loud now, but I'm feeling I could use a little more juice. I've heard some stories where guys have turned their glass-packs inside out, and it's even louder than straight pipes?

Maybe I'll just take it out and straight pipe it?

Any good reccomendations?

I have never heard of turning glass packs inside out, but I have heard of wetting them out. When the muffler is hot (eng. not running), spraying a garden hose in to mat down the glass and make it sound different and most times louder. Sometime much louder wink. This depends on how much water you spray in their. I would start out with a short spray/mist at first and then go from their.

The only thing is once you do this, you can not go back. If you do not like the results, you will have to replace the muffler.

I also remember guys using a torch or gas and burning them out also. A glass pack will burn it’s self out eventually, causing a different tone/sound threw out its life. Some times when I would switch out my mufflers/glass packs for some reason, I would be disappointed at first about the sounds. It always seemed the best sounding glass packs where the ones that have been around a while.

Also if you go with cherry bomb syle GP and you want the loudest sound, go with the shorter glass packs. If you want the deepest hotrod tone, go with the longer style wink.

More noise won't give you anymore power. Just more noise. Glass pack mufflers are nothing more than a tube full full of holes going through a larger solid tube. Between the two is some fiberglass packing to help absorb some noise. Eventually the packing burns out and they get louder. Can't see how they could be turned inside out ???

Reminds me of my High School days.

The year was 1977. I had a 1965 LeManns, Candy Apple Blue, jacked up with 50s on the back and 60s on the fount.

Duluth Central High perched on top the hill.

The downhill drive went right past the outdoor smoking area looking over Lake Superior.

Thats were the BAs hung out.

Get it up to 40 in second then let off and let it rap to the bottom of the hill. It couldn't have been a more perfect show.

The whole town is on a hill for that matter, I must have been a real PITA.

What more out of it, when the exhaust manifolds crack replace with headers.

That is the definition of cool ST!

Good times! grin

Mine was cruising School St. and Jackson in Elk River before and after school, looking for any one that would look grin

Loud, crisp rap was the key wink

COOL = Quiet

I hate loud vehicles. Especially when my neighbor fires up his truck at 6am every morning and lets it warm up until 6:30 and all I hear is the dang pipes. Then he comes home from the bars or wherever at 1am.

Keep it the way it is. Your neighbors will appreciate it.

    • How hard has he been running this 400 HP rig? Might be as simple as a plug wire or might require a compression test. 
    • Get the choke adjusted that should take care of the cold start issue. A weak fuel pump usually starts to show up at high RPMs.   If left to idle the fuel pump fills the carb bowl, as you accelerate the weak pump can't keep up and the engine bogs and bucks.  A bad fuel filter will do the same thing and is often overlooked. You probably have 2 filters,  one on the gas line and one inside the inlet of the carb.  Replace them, don't clean them.   A  fuel pump pressure test would be the next thing to do.   If your getting the bog throughout the power band then I'd suspect something electrical but it could show up just at higher RPMs or load as well.  Condition of plug wires, dist cap, rotor, pickup coil, and vacuum advance.  1st check all the vacuum lines for cracks and loose connections.  Something that old is bound to have bad lines.  While your at it clean the PCV vavle.  Google HEI distributor to test the pickup coil and ohm values.   Check the linkage to vacuum advance.  You can do a visual on the cap and rotor but its hard to find a hairline crack.   Keep us updated.  
    • I was seeing the same things on the lakes in Roseville/Shoreview. I assumed that with the cold temps over night the ice was growing and expanding causing a few of those cracks to show up.  Maybe some of the light snow helped push the ice down enough to let a little water seep through.
    • Tried wiring the choke open at operating temp and took for a drive. Still misses at appx 45 mph. Always seem to miss about 90% of the time at that speed although sometimes at around 30mph. Next question,,, fuel pump maybe or possibly the EGR VALVE. Dont have a way to test the fuel pump but thinking with the way its hard to start I was thinking possibly low fuel pressure. 
    • Bald Eagle skimmed over on Saturday.  Today after the relatively light snow there are many areas where the cracks look like water came up through and discolored the ice.  At least that what I think happened. Since there was only an inch or so of snow I am surprised that it pushed the ice down and let water come up.  Anyone else have an explanation?
    • I am assuming it was either an Ion, SM Lithium, or drill setup... If it is, no need for a slush copter. I put my slush bucket over the hole... drill... then reverse. In 12" of ice I can do 6 holes with one dump of the bucket. Every 6" beyond that takes another dumping of the bucket.
    • I have the parts on order to get the unit set up for the ice.  I ended up buying a marcum lithium shuttle for my LX7 and then plan to mount the Helix on the shuttle that came with my LX7.  I am hoping to find walk-able ice in my area this weekend and hopefully the parts show up before then so i can give it a go.  I have the pre-chirp model of the helix so with a little luck i can get them to cooperate.
    • Big home game tonight against a very young and vastly improved Calgary team.  Should be a great game.
    • I sold my old 4 stroke and bought a new electric this year because of the fumes.  Even drilling 4 holes nearly gassed me every time.  
    • I'd be careful about extending these older guys at this point....extending Koivu was a mistake and if Staal proves out and he's worth it we can sign him later...like we should have done with Koivu...but we've already been down that discussion. Agree on the 3 on 3 OT wins...we showed more aggressiveness, it paid off...and then it becomes a confidence factor which we certainly should have going forward.  Big game tonight.
