Just got this reply from Jetex regarding the exhaust system:

"Dear Adrian Han,

Thanks for e-mail.

I can assure you that the oval tail pipe will fit in the cut out correctly.

The development was carried out with Jabba and a Skoda dealer in Sweden. I have spoken to Jabba and Bedrock the two last orders supplied and they have had no problems with the fitting.

As a general comment the Jetex/Simons systems are noted for a good fit and we have always had good write ups in magazines."

So alls well again with my plans for Octy.

good luck with it.... hope it sounds better than the milltek.. might drill holes in it.:(

"...might drill holes in it".

:eek:

I think the Milltek like the engine gets better with miles but that said I don't think it was ever designed to be overly loud.

DaveU was telling me the Impreziv system may now come as a CAT back system. I believe that's a lot louder.

it has got better but i think lack of cc and cylinders is the main prob...

Ah...the age old probelm of moving from a V8 to a 4cylinder......

......had the same thing when moving from a VR6 to a 1.8 Passat.

Someone tell me for the uninitiated what engine is in a VR6? I've never known....

2.8 v6 in Golf.

2.9 v6 in Corrado.

they were very narrow angle to allow FWD mounting - quite radical back then....

Not much torque below 4k rpm but after that it flew. That said I used to take round abouts in third.

RS is faster but doesn't sound better.

i know where you are coming from.....

Any relation to the V5? (A VR6 six-pot with one less cylinder?)

And wasn't there a VW V®6 that was rubbish?

Yes - what is a V5 - surely not what the name suggests???? :eek:

V5 - is a vr6 with one less cylinder but supposedly vr5 doesn't sound as good.

Edit to explain: VR5 does sound as good as V5 apparently.

god know how they got around the vibration but does seem to work... funny how it never made it into any Skodas

So is it really a V5, or a straight 5? I know there are straight 5 engines out there but can't imagine a V5.

Yep; one bank of 3 and one of 2.

Personally I think the sound kind of nice....Audi Ur Quattro-ish.

Yeah its a Vee! I love the way it sounds , definately like the old inline 5 of an Audi. I havent heard one with a aftermarket exhaust on it yet , i bet they sound sweet! (hmm...edit my 'cars wanted' list to include a Golf V5 in a few years time...)

Icidentaly , I have always assumed that the VR engines were all 12 valves , but the later V6 engines (ie in the 4 motion golfs ect) were 24 V designs and not related at all...is this the case?

It is a v5, but the Vee angle is very narrow (about 15 degrees).

The cylinders are in a staggered array in the same block, and share the same cylinder head. Because they are staggered, they can overlap and the distance between them (front to back) can be shortened. At the same time, the inlet valves are all one side, and the exhaust valves are the other. In a conventional Vee configuration, inlet would be at the inside of each cylinder bank, and separate exhausts would be at the outsides.

The narrow Vee configuration makes for an engine which is shorter than a straight one with the same number of cylinders, with a smaller width than a conventional Vee.

EDIT: just found this site http://autozine.kyul.net/technical_school/engine/tech_engine_packaging.htm

which explains vr and w engine configurations far better than I can. The vr5 is just a vr6 with one less pot.

Yeah, the Autozine Technical School rocks

Mike, as you seem to be well informed on VW engines, do you know the story behind a previous VR6 being a vibration disaster? Duncan also relates to two separate VR6 designs. I've been told several times now to keep away from the early ones. So what's wrong with them?

I had a 12v vr6; the mk4 Golf have 4v head.

When I had the Golf I was dreaming of having the VSR inlet manifold done; very expensive at AmD though but really gave the low down torque the car really should have had.

I thought the reasoning behind the frst vr6s only having 12v was to cut back on engine complexity; basically it was an old style big engine in a small car.

Cheers.

Adrian.
