Steve Harrison's 335i (auto)
272 rear-wheel hp at 5,970 rpm
edmunds 335i (auto)
279 at 6,295 rpm
+0.5psi boost from 5000-6500rpm
Originally - I thought 300HP (Thats all?) but now after seeing the numbers - this how I had hoped it would perform -- I think I found my next coupe unless lexus can bring out something better..
So is that kind of various in a modern day electronically controlled turbo car considered normal or is there a chance that since that car was supplied by BMW they tried to tweak the boost just a hair over factory levels hoping nobody would think to check but that they'd be just that much more impressed (and get that much better numbers).
It seems back in the day the magazine's numbers used to always be a 'bare minimum' meaning you'd look at them and assume you could do better... but man these days it seems kinda rare to see a car run at the track and do any better if not quite a bit worse than you read in the mags.
I know I was reading my GS400 running 13.9-14.2 @ 99-101 in the magazines yet the best I could seem to manage was a 14.7 @ 97 with several 15.1 @ 95-96 before I got the 14.7. And that's an automatic - something that should allow for pretty consistent times.

Probably nothing more than lower quality gas in one of the cars.

I know if a car senses knock from predetonation in the combustion chamber due to poor quality gas, it will retard the spark timing... but I've never heard of a car reducing turbo boost as well. Does that happen?

I have read in the past that turbo engines will reduce boost if knock is detected. Not 100% sure in the BMW engine works that way, but I would assume it does.
This is why I take anything that I see in magazines like a grain of salt because you just never know quite what you're getting. Manufacturers sent ringers to the mags all the time in the 60's and they still do it today.

I know that i've read that when C&D or MT does their 0-60 tests nowadays they try all sorts of techniques to get the very best 0-60 times they can. Cluth-dropping, brake-torqueing (on automatics), switching electronic gadgets like TSC or VDC off and back on. I'm sure in real world driving your personal 0-60 times would be a bit slower unless you really want to beat up your car.
