I spent most of Friday night next to my phone receiving phone calls from different customers that were out running their cars and then again on Saturday. Everyone had their best times and 1 guy had his best dyno number. Below are the results from this weekend. Car # 1. SRT8 Magnum Stock 6.1L Stage 2 Heads Road Warrior Camshaft 214/222 565/547 114LSA Stock Headers Stock Catback On his best run, he left the speed limiter on by mistake and couldnt accelerate beyond 106mph. His other runs were between 114-115mph. Definitely an 11 second car with just heads/cam/Drag radials. Car #2 5.7L Magnum 392 shortblock Stage 3 5.7 Heads Very small cam 212/218 546/555 114LSA Mopar Headers Dynomax Catback Car #3 5.7L Magnum Stock 5.7L Stage 3 5.7 Heads Custom grind cam 218/222 531/533 112LSA Mopar Headers SDT Catback Underdrive pulley 90mm TB 12.5@109mph That isnt his best run ever, but it was his best on Friday night. He has not sent me his slip, but I will post it up once I get it. His best time is a 12.4@111mph I believe. Car #4 5.7 Charger 6.1 based 392 shortblock 6.1 Stage 2 Heads Custom Camshaft 230/236 576/570 113LSA Longtubes (not sure which brand) Bassani Catback He was shooting for 11's and ran a 12.09, 12.06, and a 12.03. lol. Car #5 5.7 300 6.1 based 426 426 twinscrew cam Longtubes Catback RDP Blower Car #6 SRT8 Cherokee 426 shortblock: 8.8 compression Stage 2 Heads Custom Cam 236/242 610/584 113LSA Longtubes Catback 90mm TB 475rwhp/470rwtq NA (air/fuel 12.5-12.0) 580rwhp/590rwtq N2O (air/fuel 10.5)
Uh...isn't the SRT8 speed limiter at 170 mph. I've never heard of an SRT8 run that was cut short by a speed limiter at that low of MPH. Are you sure he didn't go into limp mode because the tire height was off?
I am 100% positive. He sets his limiter at 100mph because of some law where he lives. Once he got to the track, he raised it to 120mph thinking that would be enough, but with the shorter tires, the speedometer was hitting 120mph when he was actually only going 106.
umm In your first post you mention his 426 with 8.8:1 compression. I am assuming that his 580 numbers are with some sort of FI? Which? Turbo or blower? How many PSI?
His 1/8th mile time suggests he's pretty much maxed around 12.4 seconds. Maybe 12.2 with better launch.
