The best part is that 80mm restrictor isn't doing ****. That 80mm is over 3". 3" Pipe 700 cfm = 162 mph = 0.21 mach 800 cfm = 185 mph = 0.24 mach 900 cfm = 208 mph = 0.27 mach Having tested many LS style motors for intake speed they average around 200mph. Given that is going to be a Pre-Throttle Body flat plate restrictor you can bet that its still flowing 800cfm. So 800cfm to Lbs/min is give or take 14.5 so 800/14.5 = 55lbs/min or 550hp So yea... Likely costing them 1-2hp if that.. |

yeah. rough start for Nissan. #14 retired, #41 looks to have done one lap, #28 in 2nd place at the moment. I presume will need to pit for fuel (like last season..) and will drop down.
edit - not sure if it was for fuel, but #28 still in pits.. so guessing something else happened.

My understanding:
#14 had clutch problems #41 (summarizing the radio transmission I heard) F-ing Porsche driver made contact and ripped the rear wheel off. (atleast that's what I think I heard on the scanner) And race control didn't even throw a caution for it. #28 Long stop seemed due to bodywork repairs. The rear bumper was partially ripped off before they pitted and then was taped back in place when they came out. Then it must have stopped again because it was MIA for a few laps (at least that's how it seemed) and when it came back out the hood was taped down. Also the Skullcandy #34 Altima had noticeable contact to the Driver's front causing it to go a number of laps down. Just before impact: Just after impact:

Yea another tough day
BMWs 1-6 Won't know what the deal is on 14 until we get it apart. Brad was p10 when the issue happened.. Feel bad for the team and the guys in the 41. John was picking off car smoothly .. Car in front dropped wheels in the kink and John passed him. The Porsche driver kept his foot in it and unfortunately the next turn is a right hander... John turn in and the Porsche smashed into the left rear wheel and B pilar . This then turned the car and it got into the wall. Best news John is okay We test at Sebring in exactly 4 weeks .. |

The one that failed tech had their intake system break after the restrictor allowing more air to the motor.
