I believe Dinan was equating 7 hp to the CF removal and the additional 13 hp to the rest of the modifications as he stated CF removal equals 1/3 of the gain. Also, keep in mind that this is on a STOCK setup. I believe those of us with other intake/exhaust mods would see larger benefits. Maybe not. It depends upon the mods working synergistically together. But I believe the RPI scoops would create more of the ram air effect with these boxes because they appear to be sealed much better than the stock units. Also, this is what the intake of the M3 looks like. A much larger volume box, better sealed, better intake tube design, with an oval shaped conical type filter. So, there must be some logic to his thinking. I think Dinan was right that BMW learned from the shortcomings (although few) of the s85 and applied that knowledge to the s65. Now if I could just find someone that sells the M3 filter without the CF's integrated, I could get 7 - 10 hp right there on the M3.
So the new M3 air filter is conical like the Dinan one? I wonder what the stock M3 box costs?

It would appear there are 3 things we can do to the stock set up to help with gains.
1. Try removing the screen before the Air mass meter. Although this may cause some turbulance and reduce power as well.
2. Especially for those with the RPI scoops, seal the entire air box so air only comes in from where it is supposed to.
3. look into the M3 intake and or filter.
I guess number 4 is to plunck down the dough for the Dinan box. I does seems like only 13 hp gain (crank or to the wheels?, if it is only crank then no way.) afterall but they did their due diligence that is for sure. And it would be interesting to see how it works with the RPI scoops. I never did see the CAD drawing for those scoops.
I must also add that there seems to be a dissconnect between cost and power sometimes. I have had discussions with Steve Dinan as well (at Bimmerfest) and the guy is sharp really sharp. Total engineer all the way. They obviously put alot of time and research into their products more so than most I would think. So why the hell do they only come up with so little? I guess it just seems like Dinan is really smart, does a ton of research, has alot of equipment and so on.
We sure go out of our way to dyno the competition, like RPI scoops, dyno proven for 15 hp. Evosport pulleys, dyno proven and so on. One answer might be that the other stuff is not CARB certified so they get away with more? Oh well enough said. I just want to believe that Dinan can get us the power and quality we all want. I am still looking for more though and left wanting.

The Following User Says Thank You to deknight For This Useful Post:
I agree with you. Steve Dinan knows what he is talking about, that is for sure. You would not develop a project like the 5,7 liter V-10 stroker engine with warranty without the knowledge.
One thing to take into consideration with products to the BMW M5 is that there is so much smaller volume compared to for example the M3 or 335i so the research cost per item is alot higher than for more mainstrem BMW models.

For sure good point Gustav. And thanks for posting the vids great job!

Concerning the stroker, after watching these videos it does scare me
a bit to wonder if other companies are doing this same type of
research with their strokers. Applying the same attention to detail.
I came away thinking that Dinan's stroker sounds pretty bullet proof.

+1. I agree completely. I have been considering various alternatives for "always on" power increases. At one point, the stroker was at the top of the list. Then, after weighing cost vs. power, some other alterternatives (FI) seemed the better choice. But, after watching these videos, the stroker seems like the best way to go. Notice I did not say most powerful way to go. Best in terms of research, development, longevity, etc... Now if we can just get him to come down on the price a bit!

+2 I am also one who wants my E60 M5 to last as long as my dad's (now mine) 325e 1984. I am in the process of selling my E39 M5 and as soon as it goes the money will be used to mod the E60 (and of course pay off some bills). My dad watched the video of Steve Dinan and the stroker kits and his exact words where "that guy know's what he is doing with BMW's" and my father is an electrical engineer and car enthusiast to. Quality is important to me and if I do decide to mod the E60 I wil have to consider the DINAN route. There are a lot of other geat tuners out there, just got to wait and see how the table pans out.
Weird question, will hte stroker kit drastically reduce fuel mpg? Just surious, thanks guys!
