cincy 2k+4 photo collection request / hosting - update



Oh Jason I was not taking it that way, but now you got me intrigued.
well if ya get all technical on me then you tell me...
 
3.67 final gear tranny 9a. and I was at 6400RPM 
 
maybe I need to find a cop.... he can tell me... (grin) could be worth it...
then again I could just get a dyno...

Oh I don't doubt that you were flying.. :)

224 km/h in a Scirocco (Cd=0.38, A=1.68m^2) is a very tough number to 
achieve, though. To hit it, you would have to put just a hair over 150hp 
to the wheels at that speed, which with a 3.94 R+P and an 0.80 5th gear 
(for example), would be ~6700rpm.

Not that I haven't heard from many sources that your car is fast as shit, 
but my guess is that the Kamei kit turns your Cd into more like 0.40 or 
0.42, which would increase that number somewhat more.

To my recollection, I've only seen a dyno result of a naturally aspirated 
4-cylinder VW over 150whp once, and that was Brett. (Forgive me if there 
are more of you out there -- I think Riley McDowall and Shannon Fenton may 
have been around the 150 mark, too)...

Brett peaked at 150.8whp @ 6750rpm... With his 3.89 R+P and 0.75 5th, he 
should see a top speed of 221 km/h (137mph). [An 0.80 5th would, 
coincidentally, bump that number up to 224 km/h... The increase self 
evident, of course, because as I said above, that speed would almost 
exactly coincide with his HP peak]

Either case, German auto makers generally build in 5-7% positive error in 
their speedometers... (Under German law, they can have between 0 and 7% 
positive error, but no negative error.) They all do it - BMW is notorious 
for ridiculous error at high speeds. An indicated 224 was probably 
actually around 211km/h, or 131mph... which is a FANTASTIC achievement in 
any Scirocco... much less an 8V, which likely has its power peak below that 
of a cammed 16V like Brett's. (And had a stock top speed of around 180 km/h!)

Not attacking your car at _all_ -- like I said, I heard from a number of 
people this weekend that your car was brutally fast!

Jason
