BMW M5 470 HP Upgrade
Add 70 HP to your 2000 - 2004 BMW M5. Cost: $12,500.

only 70hp, for $12.5K? That doesn't sound like much of a deal to me. :iceslolan shameless plug (http://boykinracing.us/index2.htm)

What's in this package? Is this same as Dinan SC kit? :D

Don’t know. I think it’s got to be exhaust intake and some inside engine upgrades.

The upgrade is the Dinan S2 package, and here is a link to a Car and Driver Specialty File on the vehicle:

BTW, it costs 35 grand and is more than an engine upgrade.

That's what I thought and $3500 sounds about right. :D
Do you know if that includes installation? With or without, 76 horses for that price sound pretty good to me. :D

umm no i thought i put it this is the hennessey performance upgrade. sorry.

Wow, I guess no one will go to that place after this... :D

hsk73, that price isnt 3500, but 35000..... :eek2: sorry for the disappointment. it includes suspension upgrades, etc. and does include installation

470bhp is a fairly straightforward job with the M5 engine. A colleague of mine has a Hartge-tuned M3, which consists of a lightened M3 with an M5 engine tuned to 470bhp. He still doesnt find it fast enough and is tuning it to ~520bhp. Needless to say he's insane.
