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.

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.

Yawn....

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?

SANguru · #35 08-16-2006, 07:41 PM

how do you do performance tuning without doing any baseline runs/test runs or getting any before and after dyno numbers?

you should reread my thread. the 10sec run was done in MKiV single turbo Supra putting out about 850hp. The E60 is not a rice rocket.

BTW, G-power does not have a application for the US 4.6is unless you make you own downpipe and take out the cats. There are additional cats on the US models for emission reasons.

First of all I REALLY do not understand why some people and in this case Sanguru are so provocative and may I say a bit insulting.
If you feel that your E60 M5 is an absolute rocket it is fine with me and I believe it is fine with everyone , but dont you think that EVERY person is entitled to feel the same about their car ( right or wrong ) and to try to mod it to go faster even if the primary reason for owning an X5 4.6is is not the dragstrip ???
You are dead wrong to believe that g-power does not make headers for the 4.6is. It does and I know it because my g-power 4.6is supercharged stage II
car has these headers with their complete free flow exhaust system.
I also do not understand why polishing cars and adding new rims or dvd systems is so much important and modding for going faster is not.
Anyway everyone is entitled to an opinion but I would like to mention that one person's freedom stops where the other person's freedom begins.
Thanks for reading my thoughts.

P.S. The Active Autowerke E60 M5 with software,exhaust,intake mods and nitrous pumping more than 600 hp was able to bring home a very respectable 11.1 secs. Your 10 secs are way too optimistic if you consider that heavily moded cars like Evoms 800 hp 996 biturbo can do at best a 9.4 secs and my Gemballa Gt-r 750 R (996 gt2 moded) with 850 hp running only with 100 Octane fuel ( 15 cars ever made worldwide ) can do 9.2 ( not by me ).

I foung two leads for headers today actually spawned from discussions in this group. I contacted G-power in Germany (at least emailed them... ) but have no reply as of yet.

The other firm that actually has a part number of their website is Hamann-Motorsport.com (again...taken from suggestions in this thread...and they do have a US dealer out in CA... Wheelpower.com). They have different part numbers for the 4.4/4.6 and for the 4.8. I asked for a price quote including shipping for the ones that fit my ride... lets see what they have to say. Hamann has a big collection of "body enhancement parts" offered. Some are very cool... you should check them out. They also offer, get this... "replacement engines". They are bigger displacement... and not enough technical info about them to know if they are strokers or big bores.

I'll post the info about the intercooler sometime later tonight.

the quality of the hamann crap is pretty horrible not to mention that their gains are pretty negligible. Wheelpower will probably not going to be able to get you the header either. Contact Discovery Auto. the owner goes by Shadowman on the m5board and can custom weld you some headers and tune them to your SC'ed application if you are serious. He is very expensive though.

Well I know enough about the physics of a dyno to say the results can be misleading. Let me be more clear... if you get a baseline from a dyno, then make mods and get another dyno test from the same dyno... you can probably trust the relative difference in numbers (all other parameters equal, the HP will probably not be meaningful). BUT you can not match your results against anyone elses from another dyno. The reason for this is that you must estimate some of the physical parameters of the dyno testing process (like, for example...the efficiency of the drive train... which is quite complicated for a 4WD vehicle).

BTW here is the place that makes X5 intercoolers: http://www.allardturbosport.co.uk/ The one that fits is actually for a X5 3.0D, and it is priced at $340 USD. Hoses (Which they can make) are extra.

Also this is a very good discussion of intercooling. The math can be a bit much if you havn't taken a college thermodynamics class: http://www.vortechsuperchargers.com/...oler_paper.pdf
