Yeah, I think Mercedes recommends not exceeding 45 mph with these engines. But hey, you brave souls are more than welcome to try it. Personally, I'm not leaving 1st gear.

 

i havn't tried 45 in first gear yet

 

It is crazy they built these cars so they can not go 90mph since it would be at a crazy high 3,000 rpms. A guy in Canada tried it once and his car caught on fire and exploded. His family tried to sue but since Chrysler was smart enough to put the disclaimer on page 147 of the owners manual "This car was not designed to exceed 2,999 rpms or 89mph otherwise risk of death or serious injury or both could occur."

D@mn Chrysler and their clever disclaimer!

 

So where is the danger? 90 or 3000. Could we change the rear gear to reach 90 without touching 3000? What about 45 lbs. of air in the tires? Wouldn't that help reach 90 at 2998 rpm giving a measure of safety? I believe once the 90/3000 threshold is surpassed all is safe up to 150 something. I, for the life of me, can't understand why Dammler Chrysler would build this booby trap into our beloved xfire. Thats why I'm buying a code3 pulley. Its a know fact that if the 90/3000 threshold is passed at great velocity the auto destruct is immobilized.

I wonder if you were to take a magic marker and change the 3 to an 8 on the tach if it would trick the car into thinking there is no longer a 3000rpm range for the car to hit?

 

hahaha aaaaaaaaahh good stuff guys

 

That is inspiring for sure, woody. I still want to go hard when I'm your age LOL

 

You know the solution is usually right in front of your eyes. What if we close them?

 

I will try that on the way home and let you know. I have been taking this online ninja class and one of my lessons was to blindfold myself and be aware of my surroundings using my other senses. I think I can do it!

 

I know this is an old thread -- but I did 85-90 for quite some time driving from Cody WY to Casper WY -- and YES, I was sweating a 'lil bit.

Also, averaged about 27 MPG during this drive. Drove from Cody WY to Wichita KS (992 miles). Had to slow down in Colorado and Kansas, but could floor it in Wyoming.

 

Back in '70, I had a '67 Camero RS, 327 / 350 hp. The speedo cable was broken, so I drove thru the night on I75, I70 and I65 with the tach on 4000 rpm. I have NO idea how fast I was going at any given time, but i did the 550 miles in 6 hours .....
( works out to 91 MPH average, pretty good for the day )

On another occasion, I drove Alabama to Denver in a Opel Rallye Sport that had a really tiny 4 cyl engine at 5000 Rpm most of way.

Bottom line : 3000 RPM ain't gonna bother the Crossfire 3.2

 

KBoyd, Thank you for resurrecting this thread, it gave me quite a good laugh reading through it. LOL

 

These cars were designed for the autobahn (which is not as fast as most American's think), but they can cruise well over a hundred all day if needed. i did a quick trip from the Mackinaw Bridge to Sault Sainte Marie at 100-120 for about 30 miles and the temperature gauge did not even move over the half-way point. (Top down, too). If at 27 you feel old, you need to find a 13 year old. I'm 60 and found a hot 46 year old.

 

I ran about 7 minutes at 155mph @ 6000 RPM on a highway along the Canadian border.
Loved every minute of it except for the thought of being arrested.

My Crossfire didn't mind it at all...lol

 

Ha, my 14.5 hp single cylinder air cooled lawnmower engine is set up to run at a constant 3,500 RPM.

My Mercruiser was designed for constant cruising between 3,500 and a WOT of 4,500 rpm.

My Honda S2000 got on the high speed cam at 6,000 rpm and would scream to 8,200 rpm.

I think this little German V6 can handle 3,000 rpm indefinitely.

I think a Corolla can handle 3,000 rpm all day long.

 

i'd love to do that. felony impound here in the land where hot rodding all started.

 

My SRT6 runs 170 mph at 6,000 rpm, with some tuning. That seems to work for me. I think they will runn 3,000 rpms and 90 mph for 150,000 miles, and still have a lot more to give, if you're not in jail:-))

 

Bulloney!

 

He was being sarcastic when he posted this....We all know these cars are safe to redline and drive fast on a track or on the hwy for hours !!!

 

Knowing nothing about Crossfires when I bought my first one last fall & realized it took 8 qts of oil , I knew it wasn't designed for parades .
