Hey guys

I have a 2004 XF and maby some other crossfire drivers think the 215 hp are a little bit booring , and now i want some more ponnys. The only engine upgrades i know is the 74 mm throttle body and the k&n filters.


May someone show me his ideas and witch parts i have to get ;-) thanks and sorry for my language ( austria )

 

1. Cold Air Induction ( CAI - either single or dual - single is recommended for N/A ) ( Performance auto parts & aftermarket auto accessories for your car, specializing SRT4, Crossfire SRT6, SLK32, C32 AMG, VR-4)
2. EuroCharged tune. ( Eurocharged Performance and Tuning- Exotic and European Tuning Specialists )
3. Under drive pulley set. ( evosport.com - Detailed Product Description )
4. new plugs and Magnecor wires ( Performance auto parts & aftermarket auto accessories for your car, specializing SRT4, Crossfire SRT6, SLK32, C32 AMG, VR-4 )

 

what is the under drive pulley set???
benefit???
can not find info on it.
plse help.
thanks

 

according to psurpti :

 

Read the fine print on that though. The problem is if you plan on a stereo involving high wattage your alternator CAN NOT be underdriven. Even if you dont have a high wattage system it still results in shorter alternator life. Then, if you are like me and like having a good A/C then you wont want to do it to that either. Its your car but alot of people dont understand the consequences of that mod. Buy a CAI, TB, and get a tune. You will be plenty happy, if you want more, do something substantial like wavetrac. If I had a grand extra when I bought the car that would have been the first thing I would have done, I hate open diffs.

 

thanks for all the input.
seems that the pulley is great if you don't use your xfire much.
here in my area i love to drive it as that is the reason for having it.
thanks again

 

I have a system in my car along with underglow and a few other bells and whistles so underdrive pulleys would not be a good mod for me. Does anyone make a lightened pulley set?

 

Not that I know of, but if they did it most likely wouldnt be worth the cost. I honestly wouldnt worry about pulleys of all things. If power is really THAT big a deal to so many NA owners, then it looks like more need to be following the BEGi thread for a turbo... by follow I mean call Corky and see where he stands more often .... or just buy an SRT. Like I said CAI, TB, Tune, and wavetrac... If that isnt enough, Forced induction or buy another car.... Im quite content with my car, if a turbo gets made then, nice . If not, oh well, my car still looks better than 80% of the cars on the roads today and that makes me fell quite good .

 

The K&Ns don't do anything for performance, but you won't have to buy air filters again. The best performance mod is the tune which increases hp and gas mileage, but it did not have enough value for me to pursue. If I want power, I switch cars.

 

I'll wait on the Turbo myself.. and if for some reason it falls through, then I'll consider CAI and Eurotune.. Then for real power guess I'd have to consider this:

The Camaro ZL1 Offers 580 HP With 6.2L Supercharged V8 Engine.. Just hate how you see two on every corner anymore.. Camaro.. not necessarily the ZL1..

 

My company is raffling off a Camaro convertable. LPE supercharged...600hp. We move it around farm show to farm show to sell tickets. I loved my old Camaros...I can't say that about these new ones. A lot of money for no more than you get. I would buy an old restored one before an new one. This car is valued at 88k. i wouldn't give 20k for it. Nice motor, brembo brakes, and suspension was done by LPE as well. I still don't like it. Heavy, ripped the tires off, goes nowhere fast...a lot of power and show, but just really isn't a fun car to drive like my little roadster. I can't win it, but I will be posting up some photos and an opportunity to buy some tickets. All the money goes to an Orphan program the company sponsors. Company is family owned and they have adopted children...We gave away an Orange County Chopper last year.. So, power is what you make of it. The limited's do just fine in the twistys and pretty well in the straights. Get a tune, and a cold air intake...you will surprised..

 

Even as a stock limited.. she will still give you a rush.. second gear and throttle down on a clover leaf highway exit..tires chirping..no cops watching...... Just always that need for a little more..lol.
Give me a shout when your passing out raffle tickets.. Don't plan on winning.. lol.. but never hurts to help out a worthwhile cause..

 

The evosport pulleys will run additional lights. I had them on my car with additional amps and stereo equip and everything worked just fine.

13hp... I doubt it and I did not notice a difference when driving

 

I am glad someone with them on the crossfire spoke up finally. I had to do outside research and posted what I found, the general consensus spoke only of bad in regards. Question though, stock alternator? When driving a constant speed, say 45, at night with the lights on, subs beating, how bad were your lights flickering? Just curious because mine do that now with a normal pully on the alternator. I am actually thinking of buying a bigger alternator. Anyone know what stock amperes our alternator is rated?

 

That's why I'm hesitent, at idle my lights flicker really bad, with the stock infinity amp, and the two I'm running in the trunk, my underglow and interior lights. I figure with all this and HIDs I'm running close to 1200 watts.

Speaking of electronics, has anyone tried the big 3 wire upgrade? it's upgrading the following wires

1. Factory alternator positive wire to the battery positive
2. Negative battery cable to vehicle ground
3. Engine ground to chassis

Most stock cars have 8awg wire and upgrading to 2awg or 0awg has shown to increase voltage.

 

Unsure on the Crossfire, but I have ran underdrives with extra stereo equipment on many different vehicles in the past with no charging issues, no flickering lights, and a definate boost in performance. The boost was not crazy, but was noticeable and you could tell a difference in the seat of your pants. Crossfire might be different, but I can't see any reason why.

 

There is no flickering at those speeds in my car.
By the sound of it you need to rethink how your car is setup and how are going about this problem. If your lights are "flickering" at those speeds or anything higher than an idle its not your alternator. Get a capacitor and/or additional battery.
An altinator charges your battery which it does because you are able to start your car after a drive without putting it on a charger. Your battery is not keeping up with the demand of the amp(s) thats why "flickering" happens. If the alternator wasnt doing what it is suppose to your lights would just get dimmer and dimmer as the beat goes on.
Make sence?
Like I said, evosport UD pulleys did not cause my lights to flicker with additional electronics.

People just thow in a great stereo system and expect any factory setup to be able to power it. Thats why you will always get bad reviews with any component being "underdriven" (slowed down). Car Audio stores around here sell proper batteries/capacitors but not once have they said I will need to buy one...

 

I have had an alternator cause flickering lights before. The brushes in the alt. were getting worn, while it still worked it did cause voltage spikes and would cause flikering and drive the internal computers/processors nuts.

 

voltage regulator will cause this....

 

I was going by all his stuff working properly and not needing to get a larger alternator as that would not be the problem.
IF all Components on the car work properly, And everything is set up properly, Underdrive pulleys are designed NOT to cause an issue with charging your car and will not cause flickering even with moderate electronics added.
That was the question, dont be a devil's advocate with this. a bad ground could cause flickering, hitting the fuze pannel with a hammer could cause flickering too but thats not the focus of my comments.
