I have a 2005 limited manual and just found this video. Its an auto and goes 90 in 3rd gear, i can only go 80. Are the cars different since on is auto and one is manual, or is my car messed up? is my gearing messed up?

There is nothing wrong with your car!

Your 3rd gear's radio is 1.723, the auto's is 1.486

Got that from the SPecs page someone posted here.

 

It is possible.
The rev limiter is usually set at 5740 RPM's

You can have the rev limiter remapped to allow 6800 RPM in any gear you choose. I have my manual mapped to allow 6800 in 1,2,3 but only 6300 in 4,5,6. I don't recommend 6800 in 4,5,6 as you may get valve float which, at those speeds, could be dangerous.

This will allow one to go over 90 MPH in 3rd. It also helps that first gear launch issue.

It will also void your warranty.

You should change out your injectors if you want to do this or you will run lean.

Why is valve float more dangerous in different gears?

 

This seams like it would help with 0-60 times also? And how do you have that done?

 

In fourth gear valve float means you lock up the engine at 140MPH. Kinda hard to recover from that unless you are really, really, really good.

That's three really goods.

I'm only one really good.

Get a dyno tune from somebody like Eurocharged or TVT.

I guess I dont' know what valve float is, then.

I thought "valve float" was when the engine is turning so fast, that the valve doesn't have time to close - it actually lags the bump in the cam that caused it to open. This would cause intake and/or exhaust flow in and out of the combustion chamber to be "ragged" or whatever term you use.

Meaning that the engine would not run right, would not deliver power properly, and would self-limit it's speed.

I don't see why the engine would lock up!?!?!!? Are tolerances close enough that you have valves and pistons hitting each other at this speed? Or am I just not getting it?

 

I don't believe we have interference engines but, I ain't gonna try it.

In any event, have you hit your rev limiter at high speed. It just shuts the thing down. Even for a second, you don't want that at high speed. You can lose control of the car quite easily at 140 MPH.

It will instantly turn your Crossfire into a short range cruise missle. You know they don't put landing gears on cruise missles for a reason.

Ok, got it. By "dangerous" you meant dangerous - not "dangerous" to the engine, but to YOU!

Ok, I'm with ya now. Is my definition of "valve float" anywhere close to right?

Yeah, you're right.

Nitey nite.

I haven't trapped it at the track but I believe you are right. We'll know in a few weeks when I get it together and go to the track.

Assiming I don't blow the shift to third,

plus your manual has 6 gears while the auto has only 5 so gears are gonna be diif to end up at around the same top end as the other car in the final gear.

 

Franc, you said the rev-limiter is at 5740......I thought it was 6,000 or higher?

When R&T tested they said it would do;

@6,000 in

1st 31 mph
2nd 53
3rd 80
4th 111
5th 138
& at 5450 6th = 150 mph

 

R&T are usually pretty accurate but not perfect. R&T also said the HP was 219 when it was really 229 because of Benz marketing.

I'm just passing along the info I got from Eurocharged when they did my engine. I have no idea if the specs are in stone or in general. You know "contents may settle during shipment and handling" kind of thing.

I do know where my rev limits per gear are now! I peg 90 MPH+ in third.

I must have missed that R&T, the one from Oct'03 says 215 hp although it is said to be 219 hp. Please post the R&T article as I keep them for the records.
RoadandTrack.com -- Road Tests - 2004 Chrysler Crossfire (10/2003)

 

you're right.


R&T posted 215 HP.

One wonders, where did they get that number?

Franc

 

They were testing one of the first ones, and the info they got from Chrysler was probably a little off. Most likely due to production specs not being completely locked in at that point.

If you look at the comparison chart for the Nissan and the Audi in the article linked above, the numbers for one of the other cars are out of whack as well.

If a base Crossfire will do the 1/4 mile in the mid 14's, in my experience that's a pretty quick car, regardless of the hp number.

And I love the fact the car only books in at 3000 lbs.



Sorry, didn't mean to intrude....

 

No problem adding a little info. The only real issue I have with the car is the HP, I would have thought another 35 would have been easy to get from the factory. So when my five year warranty has gone bye bye maybe I will add it myself. Heck the 300 puts out 250,3.5 ltr but still.

 

Heck, 35 more HP is fairly easyto get out of ht NA. And I will testify, it makes the Crossfire a whole different animal.

When you do finally do it, you will enjoy the new ride.
