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

http://www.dragtimes.com/Chrysler--C...ag-Racing.html

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:

There was never a question regarding this. No need to set any records straight here.

Yes, I didn't like your "destroy" comment and it was only related to slk32. Not sure why you are bringing in the SRT-6 into this. Also the top 4 times for the SLK32 only equate to 2 cars. That is not "destroy". Your twisting of the facts only shows disrespect to the C32.

I already posted earlier regarding your questionable analysis on this subject. But if that is not enough, here is what someone else that actually owns a SRT-6 said.

BTW, the 181mm pulley is not the largest pulley. And what have you done with your former SLK32? As a member from the E55 forum says " run your car, not your mouth".

He knows the 181 isnt the largest pulley and Steve isnt shy,he runs his 32 :zoom:

I could've sworn that Jake (loungn14) mentioned about his old C32 ran high 11's before from one of his posts and that he was going to share the timeslips. Correct me if I'm wrong, but it was in of the older threads.

I have seen Jake's old car first hand. It was hardly stock, but would put down the 11's. Jake would have to answer those questions though. Eurocharge is helping us all go faster, quicker with the same drive trane platforms. I like the slk's and will own one someday. Just about had a C for my wife until the deal fell through. The 2 XF's I own and play with, have made me repect AMG and I was already a fan of MB quality. We all share similar tastes which ever way we go. And I agree, we should be after the ricers, and those old "muscle cars" that I use to like....lol Talk to ya all later...hopefully at a "test and tune" somewhere...

Also a 2-fer XF owner (SRTs). Bought a coupe and HAD to get a roadster. Have owned a zillion cars and these are the best I have ever owned. Sold 5 of my muscle cars as I have lost interest in them due to the XFs.
LOVE the cars and someday hope to own a "real" Mercedes.

BTW Ran 12.5 spinning through 1st & 2nd in my SRT6 coupe with a C3 pulley.
Have a 192mm pulley (the biggest?) on my roadster.
:zoom:

I helped him install the needswings single CAI. Everything went good there. The supercharger is a lot more noticeable. The C32 still pulls a little on his SRT-6 even after intake. I'll post up a photograph later.

:y

He now has Eurocharged Stage 2 ECU, CAI, ISO, and Supercooler... We got some runs in. C32 might have a slight pull still. Overall about dead even. I'm running as low as 13.4 at the track. If I can get traction better off the line maybe hit into 12.9's or 13 flat at 5500ft.

I'm confused... the SRT owner has all of that, and STILL only runs 13's? :eek:

Does the altitude really kill power that badly?

Most stock SRTs are in the low 13's, and some high 12 factory freaks have been noted.

Yes... Not to mention I have 120k miles, and he has less than 40k on the clock. Of course I'm still impressed he can be dead even with me off those mods no pulley at all. Let's not forget I have the 185MM and all supporting modifications... :)

SRT-6 owner reports feeling the extra power to weight on my C32... :) He might see this, and I feel kind of bad mentioning, but it's a good laugh. First time driving my C32 the SRT-6 owner gets an 88MPH in 60MPH ticket... Thanks for driving that night man! :P

I know I am jumping into the fray a bit late here, but as a former Limited Crossfire owner myself (non-SRT), I have to just comment on the surprise expressed on the Crossfire's weight. Why oh why Chrysler/MB did you decide to make the SLK/Crossfire so heavy? With Limited 225hp MB Spec 3.2L V-6, the car was painfully sluggish at low speeds under all of that 3200 pounds, even with the 6-speed manual that my car had. Interestingly enough, the Crossfire pulls extremely strongly from 60-90 mph (power torque band weighted on the high-end) versus my C55, which has amazing grunt on the low-end and from a dig, but at highway speeds the C55 is out of its power band and you don't get the "pick-me up" I felt with the Crossfire.

+1, the quickest/fastest of them is in the high 11s and not consistently (I am discounting the E55 conversions that have been done since those are low 11s/high 10s) ) . It would be more accurate to say low 12s with the SRT-6. Very highly modified ones run high 11s. They are ONLY quicker than the C32 IMHO because of the 1. Engine bay room to work with for mods and 2. About 300 lbs lighter than our sedans too. At Morrocco, I'd often see them doing 12XX-12.50 at about 112-114 at best. Engines are identical. Its the mods that make the difference. Stock SRTS are just a lil quicker than the stock C32s and its mostly trap speed advantage. I am not discounting them at all because they are monsters when modded...............

My Kleemann is the opposite. Could be due to the SC, BUT the low end grunt is NOT what the C32 is, BUT on a roll-on, the things a monster?? My C32 runs out of breath before the C55 does.

Results from dragway last night. SRT-6 was able to pull off a 13.5 even. 13.6 was my best run last night. However, I did run a 13.45 few trips back.

I need to get over here more often. :)

Eurocharged 181 & Tune - NW Single CAI - NW Catch Can
NW PSK - Big H/E - Johnson Pump - 20+ PSI - 12.30 @ 111 w/ street tires

Gee, I think there's more Crossfire owner posts in this thread than MB owners. LOL

I had to get in on the action... a little late though.
Both the main arguments in this thread are right in their own ways. Yeah, modified Crossfire SRT-6's can run high to mid 11's consistently. But there are less than 10 of them doing it. So your likelihood of running into one is pretty slim. How do I know? Well, I keep track, because I'm closing in on them! :eek:

As for the modded SRT-6 that is running mid-13's, that's either altitude, bad DA, or bad driving. A stock SRT-6 on street tires will run a 13.0 consistently, with good DA and a good driver.

Then there's me: modded SRT-6, decent DA, and the best I can get is 12.5. So I must not be very good at it! :rolf:

He bought 178MM and custom needswings manifolds... Not installed yet. :)

is he tuned? if he bought robs big manis they flow 970 cfm. tune is needed for this mod. did he get them from rob or another xfire member?

BTW, what are your engine mods??? You running drag radials as well??

his mods are listed on the dragtimes link

Are you tuned? Reason I ask is my father has just Code 3 pulley and Tune on Ps2's ran a 12.2, weather was about 70* but you should be close to that if its cool enough. Stock I ran a 13.17 in 90* weather hoping to cool off soon too see a good stock time, then trying to find me a Code 3 and Eurocharged tune plus cooling mods, trying for high 11's on Et streets... btw any more news on Eurocharged supercharger pulley?
