I got this e-mail on backdating to SSI

Hallo Mikkel,
vielen Dank für deine schnelle Hilfe. Also es lohnt sich für mich als Deutscher wirklich nicht, es in Dänemark zu versuchen. Der günstigste Anbieter für die alten Edelstahl-Wärmetauscher (bis Bj. 74 a´la RS 2.7) zum Umbau auf auf „Free Flow“ ist die Firma Febö in Remscheidt- Preis pro Stück inkl. MwSt. 498,-. Ich hatte nämlich zuerst auch den Umbau vor und muss dir allerdings dazu mitteilen, dass nach Info von ehrlichen Fachleuten, eine gute und echt spürbare Leistungssteigerung nur mit den kanadischen SSI Wärmetauscher erziehlt wird. Sie bieten deutlich mehr Abgasdurchlass (dickerer Innendurchmesser der einzelnen Rohre) und sind im Bezug auf die abgestimmten Rohrlängen wie ein Fächerkrümmer verarbeitet. Leider sind die WT sehr teuer und in Europa wohl nicht ? zu bekommen.Ich habe vor nicht all zu langer Zeit den Hersteller bereits mehrmals angemailt (www.stainlesssystemsinc.com), mit der Bitte mir doch einen seriösen und kompetenten Lieferanten in Europa zu nennen, allerdings bis heute keine Antwort erhalten. Es ist also bestimmt Vorsicht geboten, sofern du dich in den Katalogen von FVD und Cargraphic umschaust. Hier sind zwar die echten SSI abgebildet und es wird in Worten auch darüber berichtet, geliefert wird allerdings ausschließlich die dänische Dansk –Ausführung. Ich wollte es von jedem Anbieter schriftlich haben, dass man mir auch die echten kanadischen SSI liefert, jedoch konnte mir das kein Anbieter schriftlich zusagen (Betrug?!). Für mich ist es auch etwas unverständlich, wenn im Forum des elfertreff über das Thema „Free Flow“ diskutiert wird, so hat sich bis jetzt noch kein einziger gemeldet, der die Sache bereits angegangen ist und diesbezüglich kompetent und nachvollziehbar seine Erfahrungen mitteilen könnte. Ich vermute stark, dass diejenigen die diese WT-Anlage montiert haben, über die zugesagte Leistungsabgabe in Bezug auf die finanzielle Investition sehr enttäuscht sind. „Mehr Geräusch, verbundn mit der Vision das Besondere getan zuhaben, bringt leider nicht unbedingt mehr an Leistung“! Hierzu gibt es diesbezüglich nur eines- vor und nachher auf den Leistungsprüfstand! Sofern es dir in punkto Qualität und Leistung besonders wichtig ist, kannst du ja mal sebst einen Versuch starten und beim Hersteller anrufen bzw. hierzu nochmals im Forum eine geziehlte Anfrage starten. Grundsätzlich wäre ich evtl. an einer preisgünstigen Sammelbestellung interessiert. Sofern du etwas in Erfahrung bringen kannst, so lass es mich bitte unbedingt wissen. Kommst du evtl. am 17. Mai zum Treffen nach Bad Wildungen ?
Mit freundlichen Grüßen
Walter

LOL

mikkel,

ok, i for one am interested to know just what the hell that means.

care to translate?

What he says in short is:


I want to backdate my exhaust too. Unfortunately I must tell you that I have been told by honest people of the trade that a good genuine and noticeable increase in power will only be achieved with the "canadian" SSI heat exchangers. They offer considerably better exhaust gas flow (bigger inner tube diameter - (compared to Dansk, Mikkel)) and are completely equal length (as "Fächerkrümmer abgestimmt"). Unfortunate the heat exchangers (SSI) are expensive and probably(?) not available here in Europe (I have found a supplier, Mikkel). I have recently sent several e-mails to www.stainlesssystemsinc.com asking for european SSI dealers, but haven't recieved any replies.

Be careful if you look in FVD or Cagraphic catalogs. Here SSI's are shown and described, but when you order Dansk items will be delivered! I wanted a written statement from each company that if I ordered a backdated exhaust they wouldn't deliver the Dansk version exchangers, but instead genuine SSI's. They didn't want to provide such a written statement! (Fraud!?)

Then he talks about www.elfertreff.de where he hasn't been able to find any hard facts.


What do you guys think?

Is the inner diameter size different between Dansk and SSI?

I have found out that Stuttgart Connection deals with SSI heat exchangers. Anyone who knows others?

[dickster]

btw are your heat exch shot? i still don't get why you want ssi's. why not put the money into other mods?

are you doing it purely for the power increase?

i guess it is your cash.

Go Canada Go!

I just sent Walter this thread: SSI Info and Pics Needed


Dickster

My complete exhaust (except for the rear muffler) is 19 years old and quite rusty. So everything needs to be replaced. In that situation I'd rather go for a more simplistic backdated system instead of keeping the - in my opinion - overcomplicated stock exhaust setup. Since I have a 231HP non cat car I don't expect any possible HP gains from any exhaust option but the backdated type. I know 12 HP is promised by some from changing just the rear muffler. I don't believe that. I've even had Willy Brombacher at FVD admit that it's unrealistic. After having driven 2 cars with backdated exhausts, where I felt an improvement in power, I have more trust in a backdated setup.

Ha ha. Yeah I don't know why Walter thinks it's canadian. SSI is american right?

Mikkel,

Porsche Shop sell an SSI (I assume it's the real thing) kit with oil pipes, both HEs, gaskets and single 70mm rear box for £1395 (€2063).

I'm not sure if this is a good (European) price or not!?


(BTW- Their website doesnt seem to get updated very often. Prices are from their current catelogue)

[Doug Zielke]

Canadian, EH??

Looked for Novato on my map of Canada, and darned if I can find it!

I believe you can get them here too

check your PM's Chris I sent you one recently

Just replied Bones. Sorry about the delay. I'm rarely on the user cp page.

Mikkel,

We have tried 2-3 times to respond to your email address, but each time the email was returned to us. Your best bet is to call us when you dont receive a return email.

Next Thursday a "vendor" is flying from the Netherlands to discuss being a European supplier of SSI's. FVD has contacted us several times and praised our products but has never bought from us. I find it interesting that they are selling Dansk. This is exactly why the wording used in the Excellence ad aimed to point out the fraud in our own industry.

The tube size in the SSI's are 1.5 inch. The Dansk use a tube measured in MM's that ends up a tad smaller than the SSI's. Our products flow a "little" better over the Dansk ONLY because we have a collector that is TIG welded (no weld penetrates the inside like the MIG welded Dansk) and one piece tubes instead of the welded together tubes that Dansk uses.(They cannot make a bend that we can make so they piece them together)

Dont forget: You can order from Pelican Parts. They normally stock the SSI product.

Hey Brad!
The Blue Bomber loves her SSI's.

I'm glad I followed your recommendation to pair them up with a Dansk 2/1 sport muffler. Great sound. Excellent power. No hassle fit.

Another happy customer!

[speeder]

As I stated on the other SSI thread, actual performance difference between SSI and Dansk or factory '74 H.E. is probably not measurable, but even if they were dead equal the SSI wins out due to quality and beauty of the pieces. What other aftermarket part would be considered an improvement on a concours level early 911S? I rest my case.

And no, I am not affilliated w/ SSI nor do I get a discount from them for these testimonials, (I wish), I just wish that there were more aftermarket parts this well engineered and built. The only downside to SSIs is that they only provide a substantial performance boost on SCs or '75-'77 2.7s, they need to come out w/ more products.

Great! This was the kind of info I was after. My e-mail should work fine? Mikkel@roadfly.com

The problem with british sellers is the strong british pound. The problem with pelicanparts is the duty that I'd have to pay here in Denmark. A dutch seller might be interesting, but I guess I need some patience then.

So to sum up: SSI are more well-made. Have slightly better flow and the performance gains with SSI should be a little better than with Dansk.

Good. Now I'm not feeling so confused anymore.

Brad Roberts

It seems you're part of the SSI company? Do you know for sure if Cargraphic sells SSI or Dansk. Walter (the German who e-mailed me first) just wrote me back and said that he apparently was wrong. Cargraphic DOES sell SSI heat exchangers and not Dansk? Brad can you confirm this? I have no problem with ordering from Cargraphic (German company and no duty).


Another thing:
I guess I'm being stupid, but I can't seem to find backdating SSI's for 78-89 models here at Pelicanparts online catalog???? I found this: http://www.pelicanparts.com/catalog/shopcart/911M/POR_911M_exhaus_pg2.htm#item3

However these SSi's are for earlier cars. If anyone knows the link for where the backdate parts (for 78-89) are shown please post the link here. If the price is the same for backdate exchangers (?) then they are cheap!!! 425 USD is much cheaper than Dansk.

I know I keep on asking questions but I always do that before buying something expensive

[speeder]

Mikkel, That catalogue entry could be a little clearer, but those would be the SSIs for an SC, they are 1974 style, hence the description, I guess. They are $425 each at Pelican.

Hmm ok. So the ones for my 84 Carrera 3,2 aren't necessarily also priced at 425 USD? If they are priced at 425 then it's very cheap compared to danish prices. In that case I might not care about danish duty and simply buy from our host.

I have tried searching for parts under "SSI" and "backdate", but found only those above??

[speeder]

Mikkel, They are the same ones for a 3.2, they do not make another model for Carreras. $425 each from Pelican.

Thanks Denis

I was under the impression that these were the OEM style for earlier cars and not the conversion items for later SC/Carreras. I guess I need to e-mail Wayne now for more details regarding sending costs, delivery time, how to pay etc.

Oh and I also have to find out how much the duty here will be

Anyway now there's hope for my plans
