C7 ARH full length header results
C7 ARH full length header results Unfortunately we weren't able to get a stock baseline with this car, as it had already been mailorder tuned and had other parts installed. Customer and us had some issues with the other parts that unfortunately couldn't get address within our required timeframe , so it was a mutual decision to install a set of brand new set of ARH full length headers we had sitting here and return the cars calibration back to stock. One thing I must say first is these headers are simply a breeze to install. They do not require any lowering of the cradle and literally will fall out of the car if you do not put a bolt in to hold them up. Mid pipe lines up perfectly in the tunnel and slip on to the rear section with ease. Now on to the numbers. I must emphasize that these are fully warmed up dyno numbers, the actual coolant temp you'd see on the street , as i have seen inflated numbers from running these cars cold. For reference stock m7 c7's dyno roughly 410-415 on our dyno.
Stock calibration+ ARH headers w/cats: 434 RWHP 436 rwtq (a lot of knock retard)
CMS tune + ARH headers w/cats: 449 RWHP 451 RWTQ
both runs of course on 91 octane.
Next week we'll be testing ARH's mid length header system on a c7 z51 A6, stay tuned for numbers on that.

I'm loving the power they are getting out of these motors. It's still so early. Headers and Tune means 450WHP/TQ....I would love to get one in my RX.....Hopefully the crate motors aren't too technically attached the chassis. Some day....
