Case Study # 161 - BR Bullet Muffler RULES!
Those are some amazing numbers for the limited mods. The IX's continue to amaze me with the kind of power they put down with a few bolt-ons. This is also a testament to Al and the folks at Buschur. Keep up the good work.

Seriously though, I did break the car in pretty hard. I was laid back until about 150 miles and then did 5-6 6000rpm pulls per day. I drove it pretty hard from 150-1300 miles. Not trying to start the debate on the best break-in method, just throwing that out there.

I was just impatient and wanted to get on the car right from day one. I read enough about people breaking in their cars aggressively with no detriment, so I figured I'd go for it.
Holy crap is 322whp on a TBE, 21pis peak ,and no tune high! The air and gas must be different over there on the east coast. Stock IX's do about 255-260whp on our dynojet AWD dyno. Add a TBE and run 21psi peak (dropping to 18psi) and power goes up to about 295whp. Maybe our dyno reads low?
I did an EVO IX last week with a cat-back, K&N filter, boost control, & my flash. On 101 octane & spiking to 24psi dropping to 19psi it made 345 ft-lbs & 330whp SAE. We never hit a knock threshold but did hit a timing limit. As I suspected we reached a point where I could add 2 degrees of timing and it would make miniscule difference in power or torque (1-2 horsepower). I was running about 5-6 degrees more timing than I could run on 93 octane. Sorry I'm just a little confused on how much difference there is in our the power and torque figures, even though we should have the same dyno.
BTW if this car makes 355whp and 365ft-lbs, it should run about 116-117mph in the quarter, that's what our customers run at the strip at that power level.

Uncorrected numbers + COLD = what you find on the 1st page.

Al, how does your dyno read compared to the DynoJet at topspeeds? On my aggresive tune (24 psi if i'm correct) I made 340whp and 360tq but then when you did a more conservative daily tune I was making 320whp and 340tq. These numbers are still awesome but it's almost 35 whp less than this guy, and i'm still spiking at 23 and holding at 20... is the 1 psi and cat back making that much of a difference? Or is the dyno reading different? It's kind of dissapointing that I could have made so much more power.. :\

These figures may be slightly higher than top speed sue to the colder temps here yesterday than you would find in Atlanta
I would discount them by 10 whp for the weather - the car is still making kick *** power
