So I haven't had a performance car in 12 years. I quit fooling around with cars (I had several cars with lots of mods) to start a business and a family. The business is good, so are my kids. I'm not wealthy and a turbo 911 or Corvette doesn't fit my current lifestyle so a nice low mileage 2008 M5 was just what I was looking for. It's not my daily driver and i'm not afraid to modify the car- But i'm 40 something (all grown up) now and don't want to build a 4 door drag car, just have *more* power that will still be- for the most part- reliable.
My wife thinks it a 535 or a 328 or something classy and anything but the beast it is. She thinks I should have the suspension looked at and the transmission because there is obviously something wrong with both of them- the ride is rough and the shifts are 'jerky' in her words. Some day I will come clean but that time isn't now... My kids are going to rat me out if they don't get blackmail pizza on Fridays "Don't tell Mom".. I'll pay for this.
So I started reading this forum before I found the car and it has been a wealth of info so far and I thank the senior member here for the tips, tricks and experience that are shared for people like me. I read on here recently from another poster that he considered himself a '2nd generation' owner that bought a $40k (or $30k) supercar and felt like some of these new owners would breath a little new life into the E60/61s. I kind of identified with this and I see a lot of posts from 2006-to 2012 that are relevant to my searches and less after that time so I hope I can contribute something here as I own the car and modify it.
I bought my car with 40k miles on it. It has H&R springs on it and I was worried it was a track car for 39k miles but could find no trace of abuse or hard driving. After reading for several weeks here I followed good advice and installed:
E-Mann Race mufflers (with stock cats and stock mid pipe) that gives me the sound that I want without terrorizing my neighbors. I sounds better than an F430 to me.
I removed the stock charcoal filters from the air boxes (thanks again M5Board members!)
I changed the angel eyes over to LED- thanks again for the info guys!
I learned about 50 nifty things about the car from posts on here. Launch control, S6 mode, etc- confusing for a new owner waiting for the owners manual to arrive in the mail. (dealer lost the originals)
I bought the Viseeo Tune2 Air for the radio. Its awesome.
I dynoed the car on the local guys dyno (they work on GTRs 99% of the time) They said a stock GTR makes about 370 on their dyno and the M5 made 387 rwhp. That number seemed to jive with conservative reading from other members here. I just look at it as a baseline number. BTW the mechanics at the shop (remember that 1100 hp GTR's are pretty normal around there) were kind of amazed the sound the ol' V10 made on the rollers. They laughed and said it sounded like a video game audio clip. They loved it even if it didn't make 800 at the wheels and were impressed with the power and curve for an NA engine.
I refinished my headlights following the great advice from a member here. It took forever but they look brand new. My wife keeps asking why I keep working on the 'new' car...
I am buying a few things for the car that I want and they are pretty major mods but I don't know how fast I will get them in- I want to prepare for them now while I get them ordered and ready. I have looked on the forum a bit but honestly the years of information on here make searching somewhat of a endeavor at times. I am purchasing a 5.7 stroker motor (good deal) that I am sending back to be freshened up- It came with a SMG gear box that is in good shape so I basically have spare motor and gear box ready to go. Roman at ESS is going to sell me the supercharger kit/ SC Tune that I may or may not use with the blower (lol, who am I kidding, right?)
Anyway, I have a reasonably extensive automotive background and a whole set of my TV repairman dad's tools (thats a movie quote for you young guys) so I expect that I can work on the car even if it was built by a bunch of genius engineers named Fritz and Hans. What I can't find on M5 board is a link to the OEM technical manuals or really good aftermarket tech manuals so I can understand what I am about to do when I work on the car, know what the part numbers are of the parts I will need and when it goes back together what I need to do/ know when to push it down to the indy shop/ dealer to have something done that I can not do myself. I assume along with the manual I will need diagnosis tools/scan tools.. I see references to 'Auto' something and some other acronyms for what I think is a scan tool from reading. Can you guys enlighten me once more?
Thanks again guys and will post my experiences on here for other that come here like I did.
