My 74 did not want to start or run worth a s*** today, actually, it hasn't run very well the last three days." My '54 hasn't been enjoying the humidity to much either. The first thing you need to do is get a dry rag, pop the distributor cap, and dry it out. Moisture can condense inside the distributor redistribute the spark in pretty unfavorable ways. You may also need to check the wire that runs to the points and make sure the seal where the wire enters the distributor is in good shape. If the spark plug wires are getting old, they can also be affected by humidity. I've heard of a product called "Wire Drier" that can be sprayed on the spark plug wires to displace the moisture, but I hear spraying the wires with WD40 works too. I have never tried the last remedy, because drying out the distributor cap is usually pretty effective. Be sure to wipe down the outside of the cap while you are at it. Hope this helps!

Does this sound good? I don't need it right now so I thought I would pass it on to everyone. If it's good enough I just might buy it for safe keeping.... what do you all think? If anyone needs it let me know privately and I'll give you the info... John Miller, FoMoCoNUT With the disc brakes, it might be a 28 spliner.

Driveshaft it saves weight. that is all it does, and it is not a stronger driveshaft necessarily. the advantage is that it takes more energy to accelerate/decelerate rotating mass than it does non-rotating mass. saving 1 pound in the driveline is like saving more in the body. it increases acceleration and deceleration and should make for a quicker revving engine, even more then saving weight in the body/chassis/interior/etc. can't give you a ratio, but the savings is ALOT more helpful on rotating parts. what kind of racing? check out some other types. i think the newer explorer has something like carbon fiber driveshafts. not sure though. the aluminum also cuts down on NVH. it won't last as long in severe service though. aluminum has a short fatigue life and when it goes, it lets loose completely, where as steel mat just keep bending before letting go, giving a longer warning period of its coming demise. sleddog - ---------- From: Brett ITT 41[SMTP:bwallen Sent: Wednesday, July 08, 1998 9:00 PM To: perf-list Subject: FTE Perf - Alum. Driveshaft First, thanks for all the responses on my last question on colder plugs. Now, I am considering putting in an alum. shaft into my racing ranger. The drive line shop wants $300 bucks for a custom made but I was thinking that the aerostar van used a alum. shaft. Does anyone know the length on a aerostar shaft? The dealers computer doesn't give the length. I was figuring I could have it cut down to my 51 1/4" cheaper than having one custom made. So all that said what sort of advantages does an alum. shaft make? Other than weight reduction. How will it affect accel. and stopping? I ask this because it was just allowed in the rules this year and I am curios if it is worth the trouble.

They are a little noisy in the 1900-2200 rpm range, but above that they quiet right down. At freeway speeds You don't hear them. They are a lot quieter than a 3-chamber blowmaster, a feature I like a lot since I can usually get away with a lot more stuff if I don't attract too much attention while I do it.. (-: Had 'em on for 2-1/2 years now (41,000 miles) and no external signs of rust yet... time will tell how long they last. Dunno how well they flow.

The Dynomax turbos are quiet when the throttle plates are closed or near closed. Once you get serious with the go pedal, they sound real nice. I can hear when the secondaries open on my Edelbrock 600 carb. in my truck. When I get close to maxing out the cam (an unfortunate 4000 RPMs), the exhaust sounds like a Winston Cup car - sounds even better when driving down the highway with concrete K-rails on both sides of you. Of course the amount of sound and type of sounds depends on the cam. The intake duration of my cam at .050" is only a puny 204 degrees, but the exhaust duration is 216. You get a nice exhaust note. >besides, a muffler is not always the most restrictive exhaust componant and >therefore a freer flowing louder muffler is not always a performance >improvement. every vehicle is its own case. Yeap, thats true. Especially when the heads are stock smog heads with thermactor provisions - can you say flow problem?

(most people have too short of a collector - i know i do!) david vizard's article was in drag racing monthly. at first it seemed to me to be a bit off, but after really thinking about it i have come to the conclusion that for race cars, and even street cars it should work. in fact i think that it may increase most street vehicles output by a oticeable amount. too bad noone sells the expansion boxes. you need to make them yourself. sleddog - ---------- From: Mike Schwall[SMTP:mschwall Sent: Thursday, July 09, 1998 6:53 PM To: perf-list Subject: RE: FTE Perf - best muffler?

Fun facts to Know and tell: Dynomax uses non pulsed flow numbers, ie: straight flow, to test their mufflers. Flowmaster requires a pulsed flow, just like a real engine, to get the correct flow capability out of their mufflers. So, the Dynomax is going to appear to be a higher flowing muffler, BUT the Flowmaster will start to scavenge the exaust gasses in a real vehicle, where the Dynomax won't.... We found this out with a stock car on a chassis dyno, a couple of years ago. Pretty cool, huh?

No problem, I was expecting it - left the door wide open on that one. Two years ago a friend and I were faced with the same question that started this thread - "Which muffler is the best?" We looked in all the magazines and saw all the typical ads which claimed "their" muffler was the best. It was amusing to see that several mufflers claimed to be the best. So we dropped some coin and bought several mufflers: Flowmaster 3 chamber, Thrush, and the Dynomax turbo. We tried each muffler on the test vehicle - an '82 F150 with a 351W with auto trans. The engine was not race prepped or anything, just a basic stock engine with a mild cam (something like 218/218 duration - I don't remember the lift) and Edelbrock performer RPM, Holley 600 CFM w/vac secondaries, and (cheap) Headman headers. We "Y" 'd the headers to make one exhaust pipe so we didn't have to buy two of each type muffler. We used 3" pipe between the "Y" pipe and muffler, and the same diameter pipe out the end of the muffler and had it bent to curve out toward the side of the truck. We then went to the local drag strip (Alamo Dragway) and ran two passes per muffler. The times were not that great to begin with - high 16's. We averaged out the two passes then compared it between the mufflers. There was no definite better muffler - all the times were pretty close. The Flowmaster went faster then the thrush (not by much) and the Dynomax and Flowmaster were pretty close. Wish I would have kept the time slips. The Dynomax had shorter times than the Flowmaster (discalimer: but not by much). So we figured the Dynomax design was a little more efficient than the others and assumed they must flow better. And they are a more streetable muffler (quiet when you want it and loud when you need it). Of course this was not the perfect test situation. We didn't check the weather - no telling what the pressure was or humidity level. The wind could have changed direction, the tire pressure could have changed, etc. >i would like to one day build the best exhaust system. max power is >generally made with collector extensions from headers, open to atmosphere. > collector lengths of 16"-28" or so being normal from what i have seen. > if, from the collector, the systems "looks" like this even with a full >exhaust max power should still be made. in an article from david vizard >with dyno tests to support this there is more info. > >using either a flowmaster type muffler mounted on the collector, or a >special expansion box (sized by vizard's test data), and then full exhaust >afterward with a second set of mufflers, either turbo (ala borla) or >flowmaster type. crossover tubes may be used at the expansion box >junction. >this type of system has been shown to work for 2,000 hp drag cars with less >than a 2% loss in power over a properly sized collector only.

Why not a set of Try-Y headers (primary, secondary, collector design) and then a nice big pipe (slightly bigger than the collector) then a crossover pipe, then go into seperate banks of two mufflers in parallel (for a total of four mufflers) then going to atmosphere. And have all pipes including the headers wrapped. Shhh...don't tell anyone. Anyone built the better exhaust system? Inquiring minds want to know...
