Have any one raced with 300 SRT (425HP)?

Have a good read. http://www.300cforums.com/forums/srt8-gene...new-m5-yet.html.
People, just stay away from any Dodge Charger or 300c that is a SRT-8. It would look quite embarassing being walked so easily. Like swajames mentioned the regular 300c is fodder for 550 but not any of the SRT-8s.

I'm just new in the area but give a few points in this discussion.
I'm living in Europe, owner of a 300C Hemi as daily driver and a Z28 LS1 (beefed up).
During the last 3 months I testdrove 300 SRT8, 540i (306HP) and 550i. Both BMW in Germany (1000mi test drive).
Well buttmeter performance are so:
300C and 540i
300C SRT8 and 550i
are about the same. Bimmers are much lighter. M5 is something else.
The major difference is handling. BMW are very easy to drive fast and you can travel much faster than Chrysler only because of being "confident".
As example, I drove the 540i between Munich and Dingolfing in 30' for the 93km (58mi) with 2 redlights wait. A 300C isn't able to manage a curve @220kph without a sweating driver.

My Ride: 07' 550i sport; Sapphire Black/Auburn; sport package; steptronic; navigation with R.T.T.I.; heads up; cold weather package; Logic-7; BMW MOST ipod kit; Motorola V3 snap-in adapter; rear heated seats and rear shades; anthracite headliner; sirrius sat. radio; M-aero kit; OEM style 166 Wheels with 245/35-19 front and 285/30-19 rear Michelin PS2s.
Depends, which SRT? My father has a 300c SRT-8 and I'm taking delivery of the 550i soon. I have driven his car. It is a tidalwave of steady thrust. I confirmed this with Car Test, a neat DOS-based program that calculates a myriad of info. using extensive car data. The 550 generates more accleration force than the SRT-8 (and even the M5 up to around 40mph) so it pins you in your seat harder, but the Chrysler's power band is flatter---it accelerates with less force but with a longer uninterputed flow of power. As far as numbers. The SRT is about .2 quicker to 60 and .2 quicker in the 1/4 mile than an automatic 550 (a manual is even closer). Not a big gap. Over 100 the SRT starts to pull away. I'd bet money that an unrestricted 550 can top 170 whereas the 300 hits 166 max without a limiter. Some Dinan equipment could easily eliminate the 300's acceleration advantage. But, where the advantage really lies is in the BMW's handling. My old 740i sport had better handling than the 300 SRT-8. A 550i sport will eat it for lunch in a corner.
I hope that answers your question.

Just a reminder to most people that in straight line acceleration, it's these new "blank" tronic (auto tranny) that are FASTER than a manual tranny because the computer shifts and doesn't let go of the torque in the engine unlike a driver's shifts (3 shifts in a 1/4 mile). Additionally, brake torque in an auto allows for torque building (turbo boosting in turbo'ed engines) at the start. Manual shifting usually requires a slip.

I replied in a thread over in bimmerforum about the Step being the fastest tranny in straight line acceleration. Know what an ignorant poster said to my post? "Ban." I guess nothing can ever be faster than a 6speed or SMG.
Traditionally, the winner of a race is all about the driver (shifting too, of course), which is still true, but in a straightline, the driver in a " "tronic has a mechanical advantage. Non believers, it's the true and has been proven. Look at porsche's tiptronic versus the manual.

I had to mention to the salesperson, that even though the 300 pulled great, my 550i has a more "violent" pull through the gears. I agree with you in describing it as "pinning" you to the seat much better than the 300. If you squeeze our 550i, your hat will fly off into the back seat!
Thanks for the reassurance. I was hoping it wasn't just me being a bit biased.

I'm glad to hear you say that (about the acceleration differences). A few weeks ago, I test drove a 300SRT-8 for the second time. The first time was before I got my 550i.

. The link Vegas posted above points to discussion on the SRT and includes posts from even an M5 (E60) owner who struggled against a stock SRT-8 and posts from SRT owners claiming wins - both rolling and standard starts - against other exotics. I also prefer the 550 over the SRT but we have to credit where it's due, the SRT-8 is a very fast car, and, contrary to some posts above, it does stop and corner just about as well as the 550!

Hard core drivers, or racy drivers don't want to admit that in a straight-line, "blank" tronic tranny are quicker shifter because the computer is given a simple programming instruction (unlike tracking conditions) to shift at certain rpm and pedal position.
Traditionally, the winner of a race is all about the driver (shifting too, of course), which is still true, but in a straightline, the driver in a " "tronic has a mechanical advantage. Non believers, it's the true and has been proven. Look at porsche's tiptronic versus the manual.

A properly driven manual transmission will normally be faster than its automatic counterpart. The tiptronic porsche that you mention is most likely the 997TT. The reason that the automatic is faster in this case is because the turbos maintain boost and don't need to spool up between shifts. It has nothing to do with how fast the automatic transmission shifts.
I do agree that it has nothing to do with how fast the transmission shifts.
