I don't know about 25 hp being able to produce reduction of a second in
the 0-60 time. Especially when you consider the fact that the quicker
your car is the hp needed to make a time reduction of a second is
proportional. I.E. - the hp gain need to go 0-60 in 9 instead of 10
secs is less than the one needed to for the difference in the 6.5 to
5.5 sec reduction.
I do understand what you say about the gain, it isn't exactly how much,
but as well the improvement to the powerband.
I don't know where you are buying your 2 1/2" custom exhaust, but I have
a feeling that it is going to be more than that. I had a exhaust put
on my Audi 4000S Quattro in '92, and the least expensive was $440. This
was at a place that bent their own pipe, and wasn't a custom performance,
just a plain exhaust. Audi wanted $900 for the system, everyone else was
about $600, like I said, this wasn't a performance oriented application,
either. If you go to a shop that specializes in custom performance
exhaust you are going to pay a considerable amount more. I honestly
wouldn't even trust a shop that told me that they were going to put a
custom performance exhaust on for $360, I would get the impression that
they don't know what they are doing.
I am somewhat familiar with the aftermarket world for turbocharged cars.
It isn't cheap. If you are getting things cheap I wouldn't trust them.
Engines are too expensive to be putting questionable equipment on them.
I just ordered a mechanical valve controller for my '88 323 GTX, but don't
plan on leaving it on for too long, for I plan on getting a more reliable
electronic boost controller from HKS or GReddy in the not too distant
future. (We're talking $80 versus low $900s) The electronic ones give
you more control, and you don't have to worry about them locking your
wastegate shut/open as much on a failure. I have put a air/fuel monitor
in and am putting a boost gauge in with the mechanical valve controller,
I believe in putting in safety items that will give me a warning prior to
my engine going south. I also will get a exhaust gas temp gauge and a
few other things as hp goes up.
I don't dispute that you can't do some impressive things with a Audi,
but what some people have claimed does seem just a little bit ridiculous.
The numbers that I have been getting from people in e-mails indicate
that the 200TQ does 0-60 in the high 6 to low seven second range, with
the q/m in the mid to low 15 sec range. I look into aftermarket equipment
all the time, and follow improvements with a particular interest since
both of my vehicles are turbocharged. When someone tells me they are
going to knock off TWO seconds in the q/m with a chip I'm going to tell
them they are full of it. If the most reliable shops can't do it with
custom chips, I won't believe a chip manufacturer like Superchips can
I still really don't think that the $500 is reasonable for the hp
increase needed in the mid 6 sec to mid 5 sec reduction in acceleration.
