Probably a little optimistic, but quoted from my installer based on also having the midsection, 13% underdrive pulley, and decatted headers. More likely around 650 at the crank, but 680 is conceivable in colder weather.Very nice. Although I am curious as to where the 680 HP figure comes from?
I enjoyed filming this as much as you guys viewing, glad you like!!!
I have the 4" resonators.which Dinan middle section are u running? res or non res?
What a great sounding car!
Did you ever dyno the car after the modifications to get a before and after? I haven't seen an actual dyno on a Dinan Stroker yet.
I was there with Darren when his car was dynoed at Dinan's facility in Morgan Hill on their Maha Dyno. IIRC, he had all the same additional mods as your car except he had Supersprint headers, not modified stock units. As for the air flow, you can't get a stronger fan than what Dinan has which probably comes the closest to replicating real world wind speeds.No dyno but Darren_Dallas' stroker dyno'd at around 550 RWHP. Apparently the dyno results for our V10's typically underestimate the true RWHP due to the high air flow requirements. One of my gauges for power gains has been my Performance Box 0-60 MPH times. When I had the exhaust, software, TB's, and airboxes my best 0-60 was 4.3 seconds. With the stroker best time is 3.8 seconds (with lots of wheelspin).

Let's just say from MY experience........it's rated at: Fast as HellRWHPI was there with Darren when his car was dynoed at Dinan's facility in Morgan Hill on their Maha Dyno.

Thanks, my sapphire black M5 is starting to blush and looking more like Indy red. Coming from someone who has had seat time in virtually every modern exotic, that is saying a lot. :cheers:Let's just say from MY experience........it's rated at: Fast as HellRWHP
550, 680, the world may never know, but at the end of the day that thing MOVES!:M5launch: To think you can take you kids to school (I won't be), hit up Starbucks, do 150mph on the highway to work and be 5 minutes early is ridiculous. E60 M5 RULES!!!!! :thumbsup: Vent over........:S
Don't get me wrong. I was not challenging your comments or the power of the stroker; just stating my experience. I actually raced Darren after he picked up his car from Dinan that day. Back then, my car had full RDSport bolt-ons (headers, race cats, xpipe, competition exhaust, pulley, tune) and RPI scoops/BMC filters. Of course, all I saw was a lot of dust as Darren pulled about 10 cars on me at around 150mph. He posted a thread about it on here too. haha
I've also seen that race against the CTS-V. You probably know but that's also Darren's car.
