ok i was on the highway today and i pulled up to an srt-4 and i went past him a little downshifted into fourth and pulled away from him and it went back n fourth i know the srt would destroy me but r they good on the highway cuz it didnt seem it unless he was messing wit me all i have done is headers muffler intake and msd coil pack. just curious when i pulled awayfrom him it made me feel good even if he was messing lol also what does the avenger top out at i have the msd coil pack and my gears rev out longer but i was at 120 in 4th at like 6500 rpm about just woundering

 

Yeah, I'm pretty sure he was just messing with you or he could have just been a bad driver, lol.
They aren't slouches, even in stock form. They are definitely faster than an Avenger with either motor...unless it's turbo'd of course.
Your mods do help you out too, but unfortunately, it's not a big gain.
You do have a good setup though, your motor can breath in easy, the burn is a complete one, and it can breath out easier. A catback would benefit you a bit better though and also get an underdrive pulley. Aside from that, you're about as far as you can go without spending a ton of cash with only minimal gains, sadly. [>:]
A turbo can help remedy that though...and it's supporting mods of course.

 

Top Out Im still trying to get there. The fastest so fa is 128mph. I forget the RPM's I wuz at, I want to say a lil over 5G's but she had more. How much that coil pack cost? And explain to me the underdrive pulley what is it just less weight?

 

You can get an underdrive pulley from places like this...
http://www.autopartswarehouse.com/mmp/dodge~avenger~performance_pulleys~parts.html
Howell automotive sells them too..
http://www.howellautomotive.com/inde...amp;ProdID=345
..or..
http://www.customcargrills.com/prodd...%2301%2DD25PUL
and if you click "next" at the bottom of that ^ page, it will take you to the I4 UDPs

The UDPs are supposed to be lighter. The stock UDP is about 8lbs where the aftermartket ones like the one in that last link are in the ounces, like 14oz.

 

the coil pack was 40 and 15 shippin i got it off ebay not sure how much it cost anywhere else try ebay u might luck out with the underdrive pully is it hard to install and do i need to get a diff belt?

 

I've never installed one, but it's a pulley, it shouldn't be that hard to do and yes, you need two new accessory belts.

 

hows this one
ebay pulley

 

That's kinda fishy to me. The seller has a 98.8% and it's really cheap in price...fishy. It's also a no name and 1 lbs.

 

true ok thanx
