Hey Wil: Was that Kennedy's dyno you got the 200 number on?
My 89 pulled 210 R.W. HP (3 rd gear pulls) the last time I was on it. I have stock heat exchangers with GHL single outlet muffler and MAF, plus custom mapped (By me) ECU.

Note to guys testing on dynojets, the gear you are in when you do your pull WILL affect the reading you get, you will get slightly higher HP numbers in higher gears.

Peter:
Yes..it was Kennedy's Dyno at a recent local Porsche club ( Niagara Region) dyno day.
We'll do it again in Spring...I'll try to arrange it for the club...but it won't be at Kennedy's, it'll be at another location with an identical DynoJet 248C. I think we used a 3rd gear pull.... I'll ask Bob at Kennedy'd so we can get at least "close" to a meaningful comparison.

Kevin, It would have been more convincing if you had cut out the license plate and replaced it.
The pinging sound of the heat exchangers while they are cooling is interesting on SSI's, do they all do that?

Kevin,

You're the answer to my prayers! You're absolutely right in that I have been on the fence about single or dual outs. I, after researching this BB, had concluded that the Fabspeed or Dansk sports were the way to go for performance, sound, and (hopefully) lack of resonance. You tipped me. And, thanks for the advice on painted steel vs stainless. My car only gets about 2 to 3000 miles a year on it, and has hardly ever seen rain, snow, or salt...........so the painted muff will probably last my lifetime.

One more question, though. Fabspeed has a Euro premuffler that is a lot less than the Dansk unit offered by our host. Any thoughts on why I shouldn't go with the Fabspeed and put the savings into a SteveW chip? I would still go with the Dansk muffler.

Incidentally, I had concluded that switching to the SSI's was probably not cost effective since my current OEM exchangers are in excellent condition.

Regards.

Your description is hilarious Denis. Although i'm sure you don't find it all that amusing. Sorry. But thanks for the clarification. :p

I was referring to one of these:

BTW, not trying to plug the FVD place for a sale. Just using their catalog and pictures for an example.

Another member mentioned he special ordered one from Pelican for around $350. He's pleased with his. I think it was toolman who mentioned it in the "3.2 Performance Upgrades"/Everybody vs. Lorenfb topic. Maybe it's not a sport muffler though. Those are known to be a little tinny sounding. FVD catalog refers to these as "race," I think?

I coulda just blurred the plate too. :D

All the SSI's do that. My B&B headers sounded like someone tapping on them with a small tool.

I think if you tapped on them with a small tool you could get a really nasty burn.....

Might want to check with the Dansk experts on which is sport and which isn't. Not completely sure if the painted ones are a sportier version of the stock muffler or not. I think Pelican member Danskman works for Dansk? I agree that an alumnized unit should last a long time on a limited use, nice weather car like yours & mine. But I wouldn't get a painted one if it's not a sport one. It'd be just like buying a brand new stock muffler. No fun in that. Part of the fun in a new muffler is the nice sounds.

Still, my car sounds pretty decent and moves out just fine with a stock muffler, Fabspeed premuffler and a SteveW chip. The Fabspeed premuffler is a nice one. I have it and although the alignment is slightly off, it's since been improved. A handful of people got a bad batch of them and Fabspeed's supplier/builder had square-up their jig to remedy the problem. Since has been fixed as far as I know

Kevin, Yeah, that's the one. Mine is the #170 025 100, '74 style. I was thinking that w/ SSIs it would sound like an earlier 911, more or less, reasonably quiet but free-flowing, if that makes sense?

Anyways....., I am giving Dansk the benefit of the doubt that mine is defective somehow. Saying that it is tinny and loud would be generous. ;)

"Danskman" on this BBS is Mike Jensen, the Dansk rep. He has been helpful w/ facilitating my returning this muffler, I might try their more expensive "sport" unit, that would be the stainless one, I think. People on this board say that they sound good, if I get another bad muffler from them I'm-a-gonna lose it. :)

You guys need to keep in mind that the cams used also have an effect on the SSI's ability to produce the desired power.

For the tuning effect of headers to be effective they need a certain amount of overlap in cam timing. This overlap is practically non existant in smog motors.

One of the reasons that the SSI is less effective on 3.2s (besides small size) is that the same wimpy SC cams on the larger displacement engine are even less capable of generating the strong acoustic signals that headers are capable of amplifyng.

For a relatively 3.2 the euro premuffler is a cost effective way to improve the exhaust, SSI is far more debatable.

Anybody experiencing popping on decel. I have the SSI's and dansk 2 in 1 out sport "painted" muffler? Is this normal for sport mufflers?

Eric

Haven't noticed any.

I've noticed faint popping on decel ever since I use Pre-muffler in lieu of cat..

Wil Ferch:

It would have been more insightful to have done a dyno run before your mickey
mods, e.g. drilled air box. Sounds like something learned in high school auto
shop.

Why do we have to wait for spring to see your dyno runs? Can't wait to hear
about all that new DRAMATIC horsepower from the new questionable add-ons.
Don't waste anymore time and money, just put in a 3.6.

Ya know, Loren...I'm trying to find a "middle-ground" between you and SteveW in other posts...and have actually tried to sway others to see your side, since you have great subject knowledge but, unfortunately.... absolutely no tact !

...I'm tending to be sorry I did that....see here ( http://forums.pelicanparts.com/show...threadid=145977).

Why do I have to wait until spring?...Well let'e see, Maybe...just maybe...( if you've actually followed some of these threads)...it's because I have about 11 feet of snow in front of the garage door. Does that make any sense to you at all?

As to the drilled airbox, etc....perhaps you should ASK if I did these...or did I get my car that way from the PO? ( Tsk, tsk...Loren ...you ASSUMED). I mentioned that part only for "clarity" of what the baseline was.....seeing you're an engineer, you MUST understand BASELINE values, no??

I think you may just have burned the last bridge you may have on this list , Loren....and the loss will surely be more yours than the collective grouping we have here. Shame, really.....

---Wil

Good Dr. Mark...

Don't put the defender in that category...my issue is not with you or anyone else on this list....stand-down

---Wil

DITTO!

I don't need to be reprimanded by the Good Doctor or ( now) by Scooter...as I simply defended my point to the original and unwarranted slam by Loren. Take it to the moderator if you want...or talk to Loren who threw the first punch

--Wil Ferch

Wil, as I said in the PM to you, my post above was not aimed at you, but at Loren for his snipe. That being said, I will reprimand whoever I want whenever I feel it is warranted. You may not have started the degradation of the thread, but you have participated in it. I don't hold any ill will toward you or Loren as I think you are both valuable contributors to the board. I do however, think you should both take your disagreements elsewhere. But because this thread no longer has relevance to the original subject and no longer supports the technical nature of this BBS, I'm asking that the moderators close the thread and let it descend into the archives.
