In reading engine review post, it was stated that the turbo lag is more pronounced in 225Q vs 180Q. Any first hand drivers with experience care to comment? I hate turbo lag and may forgo my purchase of a 225 if it is worse than my TT stealth.

The turbo lag of the K04 turbo is more pronounced than with the 180's smaller K03. The power is not quite as seamless, but I think Audi did a pretty good job here, and the power is great. A huge improvement over my 180. This car will throw you back into the seats, and my 180 would not.

Though there is a little bit more lag, it doesn't bother me and is not too bad. Overall, I much prefer the 225 engine. Now if they had coupled it with twin K03 turbos, that might have been a better way to go.<p><img src="http://home.san.rr.com/winefinds/1.jpg" border="0">

so I guess I will have to practice a bit where someone behind me can't decide to rear-end me if I stall out like I did the other day. Embarassing and needless but I will get it right.

I think Brad describes this well. There is a little bit of lag but it doesn't bother me, and the engine is clearly superior to the 180. I once had a Saab 9000, and prior to my 180Q TT I drove an Audi S6 for two years. Both of these cars had turbo lag that was more pronounced than that of the 225 TT (especially the Saab), but neither had the power curve, flexibility, or engine note of it. The S6 had to be kept at fairly high rpms to avoid a lull, but it was a rocket in the 30-50 or 50-70 range! I will be driving the 225 on the freeway this afternoon and will write you later about how the turbo feels in that situation. So far though, I'd say the bigger turbo of the 225 is a big PLUS for this car.

In my view, the 225q is a really fine car. The handling is very good, the brakes are great, and the power is excellent. With all this talk of turbo lag, dulled suspension, stalling out (not my experience) and such, one could easily be misled to believe that things are now bad, which simply isn't true.

There are some areas that I believe could be improved upon, such as the suspension. I have reviewed a number of posts on the German TT newsgroup, and some owners do seem to prefer the new suspension. I'm not one of them, but my opinion is not universal

I just wanted to make sure that we don't lose sight of what a fun sports car this still is, despite a few minor gripes.<p><img src="http://home.san.rr.com/winefinds/1.gif" border="0">

The MR2 turbo wouldn't even provide boost in first gear at all.

Newer computer-controlled turbos may be out, but older, pressure regulated only systems would have the turbos in at idle.

Problem is, at those flow rates the turbos don't work since they don't generate enough centrifugal force to make the impellers efficient.

I don't know really though if it helps to take them out at idle, except where you are trying to get them to spin down before shutting them off.

Turbo only provides boost under load (exhaust heat). Idle = no load = no significant boost. right?

ANY hot engine, turbo'd or not, has relatively little power at low rpm's, so why complain about the way it has little power? I've driven the 225 (hard) since last summer, and the problem doesn't exist. I'd prefer a 3-liter natural breather, but that isn't on offer (yet).

Bollinger

At idle, you can have them in or out, I don't think it matters.

I was wondering if anyone knew of a solid reason to prefer one over the other.
