MHP S4 C63 AMG on Nitrous, starting in 4th gear, it spins at 3000rpm at WOT N/A with 315 Hoosier slicks on the back N/A so no choice but to start in 4th on spray. Verified 6speedonline. That beats the previous world record held by a McLaren SLR by over a second.

Despite the weather (lots of rain) we hit the dyno with our SL65 today to see the improvements made via our v3 CDT (ECU & TCU Tuning) vs stock with BMC filters, and here are the results. We used the same dyno as when stock (with filters then too), same brand of 93 octane (Mobil), 4th gear, and...

Again congrats to Mike, Hagi, Craig and the rest of the crew for putting on another show for us, this time in 500-1250'+ DA due to unseasonably warm weather in MD, high temp was 75F for the day. Despite the air we set new ET and Trap Records for the 63 AMGs, mthis ended up trapping a new...

Video of a pull from today, we switched fuels and are running a 125 shot. Same shot size we'll run tomorrow at the track. We made 622rwhp/546rwtq SAE with slow ramp in (TQ will be higher at track) on the 150 shot as well. YouTube- DADSC63 DYNO PULL 150 shot dyno:

622rwhp/546rwtq SAE Keith's car in FL, please ignore the 55k typo. N/A numbers are low to start due to colder plugs and too much octane (nitrous fuel). Nitrous was ramped in slowly starting at 4300rpm (35%) by 6000rpm it was 80% in and 6250 100% in. TQ would have been higher had we hit it...
