Feels a bit quicker than a 318i with a automatic. lol. It's not a big turbo car, but she pulls hard. I am going to have to get used to living life in the upper RPM range. I always thought my M30 535i's were quick with the little things I did to them. They have more down low but thats about it. I wonder how much the Autothority software adds. %)

That was fun.

Be careful, it gets very addictive very quickly! I drove my Alpina clone which I just had the first thousand mile valve adjustment and put the afm on the infrared over to get my M5 at my Mom's house and wow what a contrast between the two! The M5 just pulls and pulls and sounds so sweet all the way through the rev range whereas the 3.5 gets it over with between 3500-5700 rpm. I did put ten gallons of 100 octane in the 535 and got it smogged and I must say the car really loved it! I am still running 100 octane in the M5 too, no complaints there either. Those 318i automatics go pretty good too especially downhill with a tailwind! LOL

5700rpm...? cmon ron..that l-block is good for at least another 1000 rpm...........

i plan on buzzing this one to 6500 or more daily.....

That's great, tony, but just wait until you get a ride in my SUPAFAST eta!

Hey Nathan's Dad! Got the car seat installed yet? hahahahahahaha

Seriously, did'ja find out whether the timing chain components had been freshened of late? I'd be takin' it seriously easy on that M88 if not.

Don't mean to take a leak on your tire, but that car could be a serious piece of garage art if it comes unglued.

All my best to Karrie, Sarah and young Nate!

hmmm new baby....new fast car....TT, you bought insurance lately ?? Seriously my M5 pulls strong right off the bottom, better than a m30 ,but then again a 3.91 is a big help

Steve, was there an optional ratio for that big diff BMW put in the M5's? Or are you strapped to the 3.91 or putting in another diff type?

Oooh, oooh, I know the answer to that one!!!

The M5 big diff was available in 3.91 and 4.10.

The gear sets from the e23 big-diff will fit the M5 diff, giving you a 3.64, 3.46, 3.07, etc. possibilities.

On another note, the smaller (e28/e30) diffs provide less parasitic loss and still adequate strength for M motors and turbo applications.

Just what I heard...

The Euro M5 was equipped with a 3.73 lsd just like the Euro M635Csi. The NA E28 M5 and M6 got got the 3.91 lsd to offset the performance loss of having 30 less HP and about 400 lbs more weight.

The PO of my Euro M5 installed a 3.91 lsd and the performance is quite invigorating.

Looking through the records on my car, there is a possiblity that I have a metric mechanic 3:91lsd with 40% lock up. I need to get under there and check it out. If the car is still equiped with the stock 3:73lsd, I will upgrade to 3:91lsd.
