I think this speaks confidence for Dinan: sending you a new engine on the fly.
Regarding transportation vs flying a mechanic I can understand that they would like to have the car inhouse where all of the competence is: Frank the engine guy, Steve himself and more.
Sure Dinan is supporting their product but it also appears they have never seen this issue and that this issue is a real problem given Darren and SBM6 both have it.
Dinan wants the engine to do the analysis but it is critical that they share their findings with other stroker motor owners who may not be as diligent as Darren / SBM6......
What about the fixes that Dinan will have to do once they root cause this issue? THis is where Dinan will need to prove their name / reputation.

The thing that confuses me is...... Your car ran pretty much dead on to what the computer model came up with. The 1/4 mile time from the V box... and also the 60-130 time. The horse power from your dyno seems to be a bit low (50hp)... but we all know Dinan uses a pretty drastic % loss to get its numbers.
On the video of darren racing the RacerMx and pulled a couple buses... There would have to had been 200hp added to the car. 100 hp isn't putting a coupe buses on a stock M5 unless it was in p400 mode... or the stars were aligned just perfect.
Im also confused that you guys think the car should be in the 7 sec 60-130. That is Porsche Carrera GT and Enzo Ferrari territory. The GT has similiar HP..(612) but only weighs 3000 lbs. The Enzo has just over 600 hp.. and also weighs 3009 lbs. I can't believe that the M5 weighing more than 4000 lbs.. and running 620 hp.. would have a 7 sec time.
I don't doubt that the cars are down on power.. but I wouldn't expect them to be THAT fast.
When you raced the 997TT... How many cars did you put on it.... what speed did you reach... and most important.. how well can the driver of the 997 shift?
One more thing...
Is RacerMx absolutely positive he was in P500 mode when he raced you?
Im not trying to doubt the cars performance...just looking for other possibilities to the problem.
The stroked Nowack E39's went through the same ordeal a few years ago.

PhillyM5,
I appreciate the feedback. Yes RaceMX-M3 was in P500S. Also, our cars should not be making the claimed 620 hp. We have additional modifications to the car which should put us in the 640 hp range (headers, free flow midsection exhaust, pulley, etc.).
If you review the Turner Motorsport conversion where they had Supersprint headers and put down 567 rwhp you'll see what I mean.
Now...I don't know if we should be a 7 sec 60-130 car (although that would be nice), yet I do know that a stock SL65 should not walk me and should not beat me from 60-130 which it has multiple times now over the past few weeks.
Hope this puts some additional perspective on this issue.
We appreciate the feedback. We have other bolt-on mods (headers, and in my case, RPI Scoops) that should propel the car to roughly 650+ crank horsepower, or 150+ crank horsepower more than a stock M5/M6. We should see 560 - 570 at the wheels with headers.
Yes, RaceMX knows how to drive his car very well and would not have made the mistake of P400. And if by chance he had, he would have said so. Or, in the alternative, if he had hit the limiter or made any other driver error, he would have made it known at the time and the video would not have been posted. We are not interested in smoke and mirrors, only real results.
Yes, Quinntin also knew how to drive his 997 turbo by that time and, in fact, commented that he felt he was shifting extremely fast and Darren just plain walked him hard.
We should be trapping 97-98 mph in the 1/8 mile. And yes, I do believe, based on my 9.11 60-130 in "limp mode," that this car with its proper power will be a very low 8 or very high 7 seconds 60-130 car.
Im not trying to down play the cars at all.... Don't get me wrong.
Im just trying to eliminate ALL possibilities. Its just real odd that both the stroker motors would have the exact same power loss at the exact same time.
(unless the M6 never was right in the first place)...
As far as RacerMx's driving, or the "smoke and mirrors effect"... I don't think there was anything intentional... just an idea.
Gustav...
I forgot those Nowack cars weren't stroked...
And asking if the other car was at its best isn't that crazy. Please don't try to make me look like an idiot. It not like there is 10 different videos of the stroker cars racing ALL types of proven cars to make comparisons. The only video we have is the one running MX's car... and thats it. It ran good for one video.

I just heard about the trouble you guys are having with the 2 cars in Texas. I have a good friend in Atlanta who has had a Dinan stroker M6 with custom headers and exhaust for about 10 months and has had zero problems. I also know that there are 3 other Dinan strokers that were installed in M cars in Europe and have had no problems after several thousand miles of hard driving. I would think that the engines were installed incorrectly and I would be going back to my installer. It just seems weird that no one else has had any issues except you guys in Texas maybe you guys have gotten into some bad fuel or something.
