It is the standard that is used to measured horse power.

Europe uses the DIN method for measuring and calculating hp
North America uses the SAE method.

are you sure?
I reed everywhere in magazine that V6 et LS1 loose horsepower in european version (cause of pollution restriction)

Well the US has the strictest exhaust emissions in the world for new cars being produced. If any thing I bet there is a pipe restriction in your exhaust to meet Europes stringent noise pollution laws which are some of the toughest in the world.

I just compared emission data from europe and us . It was nearly identical with the us beieing a tad tighter on emissions.

All I can say is it is the way tha GM europe measured it to get the power difference. But I do believe it has something to do with the exhaust being restricted.

I believe the quoted power is 200PS which is 193bhp.

The Euro Z28 produces an alleged 288PS or 284bhp attributable to restrictions on the intake and the exhaust. I believe this is due to the fitment of the V6 exhaust which is ghenerally thrown away anyway. The intake I take to mean the airbox and the free ram air mod frees that side up and putting an aftermarket lid or FIPK removes any restrictions I can see.

Overall, the paradox is that the US Z28 claims 305hp but is actually nearer 345 as in the Vette so what that makes the Euro version is anyone's guess. All I know is that Euro Z28's can run just as fast as US Z28's with the usual mods.

It seems the difference in rated hp results in a difference in performance. The US spec Camaro 3800s are tested with 15.4 to 16.0 for the quarter mile and 7.5 to 8.0 secs to 60 mph.

Auto Motor Sport tested an A4 Camaro Euro convertible in 1998 with 9.6 secs to 100 kph. The official numbers are 8.8 secs for an A4. That seems to be a lot slower than the cars tested in the US.

Hm ... my 'vert ran a 15.97 once in Bitburg, other than that it were mostly low 16's ... 15.4 is hard to believe with that car ...

US Camaros seem to be significantly faster: None except one of the following magazines tested quarter mile times in the 16th - which seem to be normal for Euro spec Camaro 3800s:

The only US test I saw of the 3.8 involved severe abuse and to get it into the 15's entailed disconnecting the ac belt. Hardly representative.

In any event, aren't a lot of US figures theoretical in that they are "corrected for altitude"?

and the solution
European version have quieter mufflers : RPO code VP6 which is described as "noise level control"
Solution : Catback
here is my site:
http://camaro.pougnon.com

Another part of the equation est the PCM : The European cars have RPO code NA7 for "emissions system european".
The PCM (engine control computer) has a specific part number for cars with the NA7 code.

solution: chip

Bon Jour diamonduff,

so the European PCm has got a different part number. That is interesting.

I checked a RPO code list and found that GM offers all sort of different emission systems - NA2, NA3, NAsomething, you name it. That is probably due to the fact that most of the countries and even some of the states in the US have got different emission requirements.

Do all these different versions have different PCM numbers?

And what does a different PCM number mean? Different hardware or different software? If the latter is the case it would be easy to correct that with a hypertech programmer.

Well I've got my Flowmaster catback!
Really nice sound!

I ran my first 1/4 sunday :
I was disapointed...
but .. well : with a passenger and really bad 60' : my wheels were spining:

and 80 oF ... so that's not too bad for a 6!

1/4 : 15.788
1/8 : 10.188
60 ft: 2.413
RT : .626

There's a video on my website

Horst, you need to change your exhaust!
I can't take an hypertech , I've got a 99 model

[/quote]

I know, I know.

From what I learned now:
The difference from the Euro V6 muffler to the US muffler is aprox 7 hp.
The difference to the US stock Z28 exhaust is another 5 hp.
With a Flowmaster or similar system the gains are quite substantial.

But: How can I get a muffler other than stock street legal here in Germany???? And: I do not like excessive noice. I´ld like to keep it quite.

I know someone who cut a muffler apart, gutted it and welded it back together. If you cut it in the right place, no one will be able to tell after it's re-installed. The one problem (for you) - it's loud.

I know like 3 people with german registrations running borla mufflers / cat backs with no problems, not with TUV and not with the Police.
It´s louder than stock, sure, but it´s the way most people expect an american car to sound (and look) like.
The stock 3.8 sounds like it has an electricity powered engine :roll:
No average german (TUV inspector) can tell the difference, and some know the difference but don´t complain - because they like it. :wink:

I learned not to take the whole street-legal-thing too serious.
Perhaps that´s the wrong way (especially if you live in a bigger town with clever/strict cops), but for me it worked already 4 years.

I agree with Chris, get yourself a Borla and you should be happy.
BTW, if the Borla is too "shiny" (TUeV) just scuff it up with a scotch-brite pad or some fine steel wool. :wink:
