To Dinan (full S2) or to Nowack that is the question
Dinan For:
1) Reliability- I believe I read somewhere over 1,000 dyno pulls on his own car!
2) Meticulous engineering-Took over 2yrs just to rewrite the software for the ECU
3) Warranty will match BMW's-are they confident in thier work or what?
4) Strong Dealer Network-4 Dealer Distributors within a 3 1/2 drive of my location
5) Results-477 bhp and 415 ft/lbs of torque
Dinan Against:
1) The only thing I am able to come up with is that to some it is overpriced....I guess it depends on how much value one places on above!
Nowack For:
1) Decades of experience with BMW and BMW tuning-the father
2) Design and engineering seems to be well thought out and executed
3) Results-503 bhp and 465 ft/lbs of torque at 3400 rpm! You gotta love that!
Nowack Against:
1) No US dealer network-it appears that the car will have to be shipped to Germany and back (shudder)
2) I could not find warranty info in a language I understand
3) I also could not get any info from the website on pricing (if it is there it is not in english)
I welcome any and all Nowack or Dinan proponents. I believe in a systems approach to tuning, not much interested in mishmash. Seems to me that if it is worth doing then it is worth paying for!
Here are some thoughts..
Dinans s2 pkg has been known not to perform to numbers
its great stuff but as you stated over priced
warranty is sometimes an issue even with dinan....check out the latest owner vs dinan vs bmwusa beef
Nowack
pain in the butt to deal with
many people have sent cars but when the come back they dont perform as advertised as well
no warranty at all on US soil
I cant believe im going to say this...but i would choose dinan.

Do a search or simply ask Apples & CharlesW both of whom have had bad experiences with Nowack.

Some Nowack cars really perform well, dusting SL55 AMG, Diablos, 996TT X50, Viper etc easily. No question about it, the Nowack are really fast. But some cars did not perform so well, Do a search on members CharlesW and Apples, prefferably with Nowack as keyword.
Dinan S2 also delivers, check out me from last summer with the Dinan S2 video:

Depends how much importance you place on 1, 3 & 4, versus your willingness to turn your M5 into a project in search of more performance. These are the best things Dinan brings to the table.
You may like to also look at Kelleners (www.kelleners-sport.com) and also closer to home, Discovery Automotive (www.discovery-automotive.com) who do some extra-ordinary work with supercharging the s62 engine, but also do normal NA mods.
Im sure, deep down inside you already know the answer yourself but you just want to hear "IT" from others, for re-assurance. So as the other guys have stated, DINAN all the way, for the reasons you've described.

I can also say ther are people in Europe that have ripped out a total Dinan S2 conversion and had a Nowack after that (Member Mattar).
I would say for the money Nowack gives alot more.
Hello Gustav,
I've had the Dinan S2 video for awhile now, very impresseive. You state that "for the money Nowack gives you more", I have to wonder if that includes air freighting the car to and from Germany from the East Coast? No contensousness intended, that is a real question. I have no feel for what a Nowack N500 conversion costs and even more clueless about the costs involved with shipping a car overseas and back.
...the costs involved with shipping a car overseas and back.
One-Way Costs from East Coast:
- RORO (ship): 20 days, $900 (+3% of value of M5 for insurance).
- Private Container (ship): 20 days, $1,700 (+3% of value of M5 for insurance).
- Air-Freight: $7,000 (+3% of value of M5 for insurance).
Cheers, Daniel.
PS Dinan is your best bet, if you don't want to mix-match your own selection of mods. Please note that there are many mods not offered by Dinan or other tuners, so you will likely be mixing and matching even after the tuner conversions.
