Just an added bonus for putting in the 10" dual voice coil 300 watt amplified bass tube!

Lotsa thump and no sideways jump!

 

Well congrats! If I had a spare 7500 laying around I would have to check out that one in McCallister that I sent a link to. Join the 2fer club here.. lol.

 

Way to go John , Glad to hear you settled on a 6 .

 

When the guy who wears a tie to work works in a wind tunnel, I would trust him over your 'feeling' any day of the week. We are not simply talking about how things feel, there is imperical evidence that it does not provide additional downforce, data he has seen and we will not. There was never anything about a museum, and this gentleman was an ENGINEER, not a curator. He was also retired from Chrysler and came to the hotel to talk to us for 2+ hours about the car, so no need to tip toe around issues with Chrysler since he does not work there anymore. He confirmed the 350HP on the SRT, not the 330 it claimed among numerous other things that no exec at Chrysler would ever admint.

I am not trying to be difficult, just going with what I believe to be true, no matter how many nay sayers come forward.

One question:

Why would he go out of his way to lie about engineering data? It just doesn't make any sense...

 

Are you sending this "gentleman" a Christmas card? I'm sensing some infatuation.

Believe what you will, it changes my experience not one bit. Again, I clearly know nothing about the car I owned and modified extensively for two years. Please ignore my musings.

A question for the SRT owners: would you feel comfortable swapping wings and trying your high-speed shenanigans with Flipper?

Just wondering.

 

Maybe he was practicing to take his dealership class

 

Hardly "settling" LOL... I'll have to spend some time adjusting to the additional 150 horses at the rear wheels...

 

Jumping into the fray to insert a totally random post here, but anyone with a black Base/Limited interested in doing a wing swap with a Black SRT-6? I am so-so about the SRT wing but miss the auto-retracting rear spoiler of my Limited. I know its cheesy, but whenever I revved it out of an entry ramp and saw the spoiler slowly deploying in my rear view, I always that it was awesome.

 

Ah, commonly referred to as "Fubu'd" ........ no thanks!

 

I was never implying you knew nothing about the car, but I think it is incredibly arrogant to assume you knew more than the guy who is the reason you have one. He spent 5 years of his life with the car, in labs, looking at numbers and you think you know more than him because you have modded one for 2 years? Rudy, probably, you or I, not so much.

I always thought we could discuss these things as gentlemen, but because there is the need for childish insinuations, I will not post in this thread again...

Enjoy your weekend.

 

?!?

Wow.

Whatever you say bro.

 

I seriously cannot stop laughing

 

So, assuming the gentleman behind the desk is right, and there is zero benefit from the SRT wing, would anyone be willing to hazard a guess as to why I felt more stability at speed after the installation of said wing?

If an added ~5 pounds to the rear causes that much more bite to the road, and it cannot under any circumstances be attributed to the surface area of the wing being doubled, then why aren't we just throwing a ten-pound barbell in the cavity where most folks put the first-aid kit?

Then you have ten pounds of additional downforce AND better gas mileage!

We might see a market for used SRT wings after all.

 

John, glad to hear that you have found another Crossfire..... welcome to the dark side of the club....

 

Some would say FUBARed.

I do not recollect him saying the wing had no effect rather the opposite. Simple aerodynamics says a flat plate at an angle to a moving air stream will create a force, the force created being dependent on the air speed, the angle of attack and the size of the plate. Rotating that plate to the air stream and you have an increase in lift or down force until it becomes an air brake at 90 degrees with neither lift or down force.

If you have seen a sheet of plywood poorly tied to roof racks you can see the effect of the air under that sheet at highway speed. When air coming up the windshield gets under that sheet watch out.... Lift off.

 

I couldn't answer that question as I haven't driven a Limited to feel the difference, but I could take a shot on why the downforce difference would be almost negligible between the two wings. The profile of the Crossfire isn't exactly the most aerodynamic. This creates a large wake coming off the car that causes air to mostly overshoot the wing. So more surface area isn't required on a wing, unless you want to mount it to the roof.

 

 

Just throwing it out there!

For what is worth, my Limited always felt very stable at speed. As much so as my SRT-6. I think any difference in down force between the Limited wing and SRT wing is negligible. More of a psychological "feeling" than real.

 

Abstaining from the wing/flipper debate, I just want to interject another comment mentioned by the "engineer" at the seminar in question. He definitely stated that these cars are not SAFE to run at speed (above 65 mph?) WITHOUT using some type of wing. Road stability is highly compromised as expected.
On an additional side note, he also stated that when they where in Germany, they had their choice of driving N/As or SRT on the Autobahn from their hotel to the plant, and they all wanted to take the SRTs. More fun!!!!! Just sayin .....

 

For those fishing for concrete "facts" I can say with certainty that the SRT wing decreases fuel mileage by roughly 1-2 mpg (I always do the calculations on fuel mileage, every fill-up... the nerd in me).

Pre-SRT wing, I got a combined 27mpg average per tank. This held true for thousands of miles and several tanks. After it was installed, I never got more than 25 combined. My driving is 80% highway, and I set the cruise at 80 for the full 26 mile trip to work each morning. Traffic and distance are unchanged each morning, traffic being no issue once I hit highway. Modifications to the engine were not changed until long after the SRT wing was installed. Therefore, the wing was solely responsible for the change.

This would imply that the wing is having some effect on the car. I would say more drag, but the analogy Dave presented would imply not, seeing as the angle of the SRT wing is noticeably less. If a short wing at a steeper angle creates more downforce, why does it also yield a lower coefficient of drag? Aesthetics be damned, why did Chrysler's group design a part that would handicap the SRT-6?

As for the intangible, anectodal evidence, allow me to clarify: at 130mph with the Limited wing, the car wasn't "loose" by any means, but there was a definite "wiggle" especially in windy conditions. Said wiggle was absent after wing was installed. Stability at speed increased even more once I finally bit the bullet and installed the SRT front fascia, which is lower to the ground. Trips to 150+ were smooth and reassuring. The effect was certainly tanigble, not psychological.

How much effect? No way of knowing. The difference between a B-cup and a C-cup is only an inch or two of boob, which is marginal in the grand scheme of things. But the level of satisfaction is apparently in the eye of the beholder.

Me, I'll take the big wing and the big *****, regardless of what wind-tunnels and chiropractors say.

I think we've more than beaten this horse to death... The "Flipper Crowd" can enjoy their mileage advantage, "ironing board crowd" can enjoy the aesthetic improvement. In the end, we're all driving the same damn car and very few of us have the brass to push the car to the extremes where the wing type would even matter. Right?

John, come back to the discussion any time you'd like, you big sensitive teddy bear. I still owe you a beer from your absence at the Fall 2011 Dragon...

Cheers,
