E53 Headders/ Gears?

[SANguru]

pleeease.. 30 feet.. hahaha.. btw.. it's headers not headders and gpower, dinan and supersprint make headers but not for the X5. You're smoking some damn good crack.. 30 ft..hahahaha...

I've been able to take every Mustang I've raced since supercharging... that's not to say its invincible though. I had one occasion where I ran a cobra... shut down at about 145... beat him by about 30 feet overall. At the next stoplight I could hear his girlfriend in the passenger seat say to him "I thought you said this car was fast...? you just got beat by a van!!!".

For some reason, people don't think BMWs are supposed to go fast... that even applies to some BMW owners! (nb. the rest of my races are subject to my wifes M5. Its a hotrod too with loads of goodies. Its a pretty even race between my X5 and her M5 until we get to about 150 or so.... then it all over as she leaves me in the dust).

Anyway... YES I have thought about nitrous... the wet systems are about all you can use, because the injection systems will create too much HP for the motor. Its only good to about 600-650 HP peak. I'll mess with that once I get all the HP out of the hardware I can.

Most people don't know this, but the diffs are made by Dana for BMW... and for those who have raced... know that they build almost indestructible parts. They are surely not the weak link. The stock gears are 3.91's. The only lower gearing available from any source is a 4.10 without completely replacing the carrier and housing. The transmission is a pretty stout unit too. I don't know what the limits are, but no failures yet.

I've yet to break anything in the drive line, so I must not have enough HP yet?

"I had one occasion where I ran a cobra... shut down at about 145... beat him by about 30 feet overall."

It seems SANguru questions the veracity of being able to beat a Cobra by 3 car lengths.

Warbucks.. I can appreciate your Need For Speed but I don't think the way to introduce yourself to a forum is to dis it. It's true this board is more geared to pimping ones X rather than what 1/4 mile times you can click off. But in all deference the X5, even the 4.6is, is more about stylin and profilelin than true performance.

It should cost no more than $20 for a timed run at your local track.

Yeah... you are right, is should cost $20, but it doesn't...its $85... and its only open Wednesday nights...so after getting home from work and get to the track... I barely get a run in before it closes. Its a poor investment at best.

[SANguru]

lol at poor investment.. how about this for a good investment, I bet you that you can't even hit 12's in your current setup.. We'll even start a pot here.. make sure you post videos and timeslips. Until that, all your posts are about as useless as your POS intercooler... btw.. you can still size the intercooler for height and depth.. there is a tradeoff in size vs boost lost but anyways you're so FOS that there is no point in telling you anything.

If you are daddy warbucks what the hell is $85 dollars. And wendsday nights is tough for me too. But even i could get it off at least once a year to go to the track. Shit im no daddy warbucks but i spend $85 on bullshit never mind the $85 dollars it costs me twice a week to fill up the X5. I would certainly have no problem spending it just to see what my car could actually run.

Show up and we'll trade cars for a day, and you can go run it. As I said... for $85 and one pass...its not much of a test or a bargain.

Ya know, this thread was originally about performance tuning an X, which I am really interested is...now it's what, a test of penis size?
