Extremely sorry to read the results you're having. That really sucks.
Have you guys contacted any other stroker owner?
I would find it very interesting to have feedback from them.
Has anyone else experience such problems?
Trying to trouble shoot maybe difficult. I would expect Dinan to make this right and not on your dime.
BTW when you posted the videos of the 1/8 mile drag races were the engine issues present or were your cars running right?
Reason being because I compared all my 1/4 mile time slips and I noticed something I thought was surprising but maybe the cars were not running right?
Good luck and hope Dinan come through.

No, the cars were obviously down on power at the strip. The posted 60-130 times are also "down on power" times. When Darren's car was making more power before (when he put 10+ cars on RACEMXM3's M5 and also at this time he annihilated a stock 997TT), we did not record any "times." We only started to record the times when he could only pull 1-2 cars on the stock M5.
The funny thing is that the cars make significantly more power and torque low in the RPM range <6K RPM as evidenced by our dyno comparisons to our old cars. This makes the car a much more "driveable" around-town car for sure. We are wondering if 1. Most, if not all, other stroker owners do not subject their cars to rigorous testing (runs, times, dyno's, etc...), therefore they are impressed by the more driveable feel and they are "faster" than other M5's and M6's? or 2. Not many, if any, other strokers and the requisite software have been installed in '08 MY cars, therefore possibly software compatibility issues?
I mean, Darren achieved 3.8s 0-60 and 8.2 0-100 with only 457 PEAK rwhp (DynoJet) or 399 PEAK rwhp (DynoDynamics). Those are the peak numbers, but there was at least 50 rwhp and 50 rwtq more than our old cars "under the curve." Our old cars made roughly the same peak horsepower with the bolt-ons, but again, significantly more peak torque and significantly more power <6K RPM. So, I can only assume that when the cars are "fixed," and producing peak rwhp numbers such as the TMS Stroker install, then we should see 7 second 60-130 times. We are either losing compression up top due to mechanical issues, losing air up top due to a restriction or software issue, or something along those lines. The dyno graphs on the dynojet had some strange /\/\/\/\/\/\/\/\/\/ up top. One of the race shop guys said it looked like "valve float," which would cause compression and power loss. We shall see what shakes out tomorrow.
Thanks for the concern and kind words, guys. I'm sure DINAN will get it worked out satisfactorily and we will have our BEASTS soon.

Are you talking about the 1/8 mile traps? I had asked what the traps were on Darren's car...it appeared that the strokers couldn't break 94mph....bolt on M5/M6's have topped that (yours included). When they get this figured out they should be hitting close to 97-98mph in the 1/8th and approaching 125mph in the 1/4 mile (which you probably knew )
Tom C you picked up on what I was referring to.
I had noticed that on motor I had faster 1/8 times and faster traps.
On nitrous which is set up spray in 3rd gear (from to hole it is impossible to manage) the times and traps were even greater.
On motor my fastest trap in the 1/4 mile has been 123 mph and 126 mph on nitrous.
Next month ASR (Abid) hopes to help me achieve 128 with new goodies.
That is why I question how the motors were running at that event. Chris confirmed that they were under powered. That helps to understand the results.
I sure hope Dinan comes through for these guys. They have been the best promoters of the Dinan stroker. At least that have come forward and showcased the Dinan product.
The forum watches with interest.
BTW the motors came from Dinan with the larger TB's on already right?
I am waiting to read when Dinan says, it is an installer issue?
Good luck guys,
Ranger

Juan,
Could you please post your 1/8 mile trap speed and times? We need all the data possible for real-world comparisons. We're being a little transparent right now and feel fairly stupid after investing this amount of money in Dinan products.
Please share your 1/8 mile data if you don't mind as it will help us show Dinan there are issues with the car and it's not "bad gas" as Steve would like to say.

Darren, I would suggest a leak down test as this is a much superior manner in which to test the sealing quality of each cylinder. Just make sure when you have it done that the engine is at operating temperature. Another value to datalog is the quality of combustion and duration of spark through the Ionic Module, this will tell you exactly what's going on in each individual cylinder. Dinan should be able to interperate those values, if not call me with datalogs and I'll interperate them for you. This will help determine if bad gas is the issue or some other cause.
I have attached some of Juan's 1/4 mile slips both on and off the bottle. The best ET pass was done with Nitrous from 3rd Gear up since Juan originally had a 3.91 diff and this caused tremendous wheel spin even with drag radials. My best mph pass with Juan's car was a 129.2mph, but the ET 12.7 was horrible as I hit the nitrous from the gate and had to pedal the car until the end of third gear down the track.

Abid,
Thank you sir. All the input and guidance is much appreciated and I'll pass it along. Also, thanks for sharing Juan's time slips. I think it proves we are definitely not make 630+ hp.

No problem, anytime! Just to let you know Juan's M5 was making 585whp and 465wtq on the bottle using a dynojet when we did these runs. Although, none of the slips I posted were with full nitrous power throughout the whole run.

I can't really compare the runs or power on nitrous. All motor is a better indicator and clearly shows we're not making the power advertised by Dinan.
Once we get these working properly then we'll be able to have a good comparison between Dinan stroker and ASR nitrous'd cars
