TIA!

i think it's probably not putting down quite that much HP. i do think the headers, muffler and intake setup add a bit of power. the headers are ebay / surewin & the muffler is a stebro race exhaust. the intake setup is a BMC airbox w/ fabricated plumbing as shown earlier in this thread. i probably need to calibrate the vBox for the car having lost a bit of weight. also, in lower gears, a light weight flywheel will show up on a chassis dyno as a power gain. this effect wanes in higher gears.

my guess is around 320 - 325 based on the butt dyno. it's nice!

UPDATE:

passed the 500 mile mark on the new motor yesterday. she's running beautifully. i think the studs on the transmission mounts are still a little bit too long, though. i hear an occasional clunk that sounds to me like the studs hitting the subframe. at the 1000 mile mark, she's going back up in the air & i'll address this issue. i also plan on new oil / filter along with another Blackstone Labs oil analysis report to make sure everything is peachy.

this thing is a riot; i really love it. funny story, though: when i blew the motor in march '09, it was my daily driver (yes, my track car was my daily driver). i bought an '02 XTerra 4x4 that i planned to use as my daily. literally a week after i finished the boxster, the motor in the XTerra went south!! comedy really is all about timing......

i popped that baby on craigslist for $3k and it sold in five hours. we picked up an X3 for my wife last week & i'm driving her G35 coupe now. good times.

for some odd reason, it hit 62 degrees in atlanta today. i took an opportunity to see if my paint could clean up at ALL.

i've been nervous about this. when the motor blew, i lived in an apartment. i bought a cover & the car sat outside for six months. the cover, it turns out, was not waterproof....... the car was COVERED in crap. mildew, gunk, slime, dirt; you name it.

turns out some water and a LOT of soap can do wonders . thanks, glasurit!

Lookin good. Were you able to buy just the 540i maf housing, or did you buy it with a sensor and toss the sensor?

Your red interior trim looks great. Did you paint them or was it a factory option?

i found a guy on bimmerforums who had one. when they sell the new BMW sensor, it comes with the housing. there are lots of old housings lying around.....mine was $20.
