C32 vs Crossfire SRT-6
 

So it's my 185MM vs a basically stock crossfire. He just did ISO and CM30. We raced around five times at the quarter. He averaged 14 even I was averaging 13.7 a little worse than last time. Hotter day... Very surprised by it's performance. Probably going to help this guy mod it up. As far as the runs went it was a very slight pull in the c32 or even out the entire way. :eek:

We did race once 0-125MPH and he fell back bad starting around 90MPH. Claims it was the bad pump which I can believe... :)

Nice. maybe film next time?

who was the srt-6? don't mod him too much xfires with 3 main mods see mid 11's with consistency!!

I've been bad about getting video at the dragway. Next time I'll pass my phone off and make sure to get some runs recorded... :)

I ran into this guy a few nights ago heading home... I know his cars potential and that's why I want to help him mod. It only has 35k on the clock as well... :)

Here we go again. Mid 11's as in 11.5? And consistency as in more than one car? Show me.

I thought they were on par with C32's with power/speed.. even slower due to C32's modding more (or so I think?)

Form these spec's they sure are faster.. a good second or so

would you consider 11.7 to be a mid 11 time? top 6 times on dragtimes are by 4 different cars. seems to be fairly consistent to me. the top 3 are low 11 times next 3 11.7 so yeah i would say mid 11's to be an accurate statement
considering the TOP 20 times posted are ALL faster than the FASTEST time recorded by a c32 and the engine is the same the gearing is the same and the weight difference is a mere 200 lbs or so i would worry more about getting your ride faster and less about the consistent times of a srt-6 or a slk32.

Since I don't know crossfires at all .. are the faster speeds mainly due to lighter weight or is something else I'm missing?

Take off 1000lbs and the stock engine nearly keeps a 185MM setup. I was having issues with keeping traction today. Pulled off a 13.7 after lowering rear tire psi to 25. That was with an overpowered launch spinning most of 1st. Thinking 13.2 with perfect launch.. 5.5k altitude.

c32 specs say 3400 lbs
srt-6 specs say 3240 lbs 160 lbs difference

Wow... Thought it weighted a lot less than that? LOL...

Why such disrespect to the 4 door brother?
No argument as to which car is faster. It's just this is the second time that you are putting the C32 down. The top 3 runs below 11.5 are actually 2 cars and only 1 without Nitrous. I wouln't call Nitrous one of the main mods for any m112k car. And having 3 cars (one still using Nitrous) running 11.7 out of many cars that are listed is not exactly "consistent". As far as who should be worried about what, I think that you who should worry about beating my time with any of your m112k based rides. :p:

Wait... Is this accurate?

Crossfire SRT-6 is 2900lbs
C32 AMG is roughly 3500lbs

It has to weight less than 3240lbs... No way it could keep the C32 otherwise..?

Crossfire SRT-6 Coupe is 3240lbs and the C32 is 3540lbs.

So we are talking more along the lines of a 300lbs difference. That equals out to a 30hp or so increase in the lighter vehicle. My modifications put me around 60-70hp increase. Guess that about equals out, and makes sense... Bringing up traction problems again it's about right.. :)

also much more space in their engine bay. allows for a much better flowing intake setup (see Needswings Dual Cold Air Intake) and quite larger intake manis.

that's in addition to less weight

Now, don't you guys get all worked up about the step child of MB/Chrysler. They run low 13's stock, mid 12's with a cold air intake, low 12's with a pulley, and will break the 11's with the right tune and tires. Mid 11's are not consistant yet, but a few are getting there. The rest will follow in do time. My coupe weighs in at 3300lbs/ the roadster is 3450....hope this helps clear it up a little....

Doc, thanks for setting the facts straight.

I'll take the credit as I made him aware of the post. :D (I guess)

Comparing the C32 to the Crossfire is pretty much like comparing the C32 to the SLK32. The SRT coupe has a weight advantage, shorter wheel base and maybe an aero advantage. Just about anything we can do to Crossfires can be done to MB's. There are now two and close to being three 55K powered Crossfires and I will be adding a turbo to my 500 engine in my car in the next couple of months. the 500 engine on 10lbs of boost will produce over 500 HP. Maybe there will be some 55K powered C's and SLK's in the future? It does seem the Crossfire folks are modifying their cars more but that could be becuase they are much cheaper to buy and many of us die hard gear heads are snapping them up.

As a few others have stated, it's all about weight, engine-bay breathing room, and tire contact patch. We have TONS of room in the rear fender wells, more than the SLK and C32. Most of the guys heavily modding their cars are running north of a 285 in the rear. Combine this with the ~3,200 pound curb weight for the SRT and as Lantana stated, potentially better aero -- it's no surprise our Crossfires are faster. My N/A coupe with manual trans weighs even less (2985 without me in it, on certified scales) but I have a huge power deficit from any of the kompressor motors, so I stick to the corner-carving, which my car does very well at.

The horsepower figures are identical for the C32 and SRT, despite whatever erroneous marketing you may have read. On the dyno, they're within 5whp of each other. Chrysler wasn't allowed to advertise that due to the marketing constraints.

Not sure why there's any animosity towards either car though... the Mercedes cars are our heritage. If it wasn't for the C32 and SLK32, the Crossfire SRT wouldn't exist. If it wasn't for the Crossfire crowd, many C32s and SLK32s would still be relatively stock, as the Crossfire crowd has pioneered many great breathing and performance mods.

The C32 can haul four people, and the SRT can haul two people down the 1/4 a second faster. There are similarities, but there are differences.

Embrace them.

lets set the record straight. i have never put down the c32. simply stated the facts. the slk32 and the srt-6 is faster. plain and simple. the records show it.
you didn't like it when i said the slk32 would destroy a c32. considering the top 4 times of the slk32 and the top 20 times of the srt-6 are ALL FASTER than the very fastest c32 i would call it destroy. you may not like it but its the published and proven facts.

you asked for consistency. you have 4 cars running 11.7 or less. thats consistent. mr photoman with a c3 tune and meth runs consistant 11.7's . he has the slips to prove it.
what you are saying above is that if you aren't running a 11.5 it isn't a mid 11. so a 11.6 isn't mid 11? or a 11.4? with 2 cars running 11.3 or better and 2 cars running 11.7 i would call that a mid 11 consistently. you don't.

when i referred to getting your ride faster i was referring to the c32 in general but if you want specifics, look at your sig. you have every mod possible from lsd to the largest pulley headers to tunes and so on. yet the best you can manage is a 12.4? i think that speaks volumes as to the ability of the c32 vs the other amg's with the same driveline. btw you asked me to prove different cars had consistent times and i did. see you at timmayfest!

What an angry note :D We should be fighting against the ricers instead :P haha kidding...:rolf:

I didn't get that vibe at all, I know Steve personally and he's one of the most laid-back guys you'll meet.

As he said, the facts are there for everyone to view.

I was ironic, just wanted to point it out :D All XF guys over at crossfireforum.org are very kind. :zoom:
