it was indeed 90s today during the dyno however judging by numbers alone I'm a bit depressed.

my dyno from jan 4th this year, 47 degress with everything except z1 headers, AAM test pipes:

317whp, 266 wtq

today, 90s something:

321 whp, 257tq

so, gained 4 hp, lost 9 wtq

comparing these is difficult though because of the difference in temps. anyway though it is what it is:


I had to drive home in rush hour traffic so couldn't really get on it too much but some worthwhile observations:

the smell, didn't notice at all. I thought I was supposed to smell gas/fumes with test pipes, I guess you can slightly but nothing like I expected.

at idle and low throttle hard to even tell it sounds any different when it didn't have the headers or the test pipes. start laying on the throttle and it becomes noticeably cool sounding I try to grab some internal audio tommorow for those interested.

Butt dyno - couldn't really get into much coming home so I can't really say yet. I don't like that my TQ numbers are down but just from driving eh, can't tell but I didn't really lay into it yet.

overall:
I'm bummed at the present time. I will take it up to capital drag this weekend and hope it stays in the 90s because I know before the headers and test pipes the heat affected the quarter from 12.9 108 to 13.2-13.5 from 105 down to 103 for the trap so if it stays this hot I should have a decent comparison judging how it does in 90s heat vs 70s and 80s at the track.

anyway sorry if I bum anyone out. right now I'm thinking probably not worth the investment but I'll give it some time to grow on me. It certains sounds better and surprisingly it isn't obnoxious unless you start really getting on it and even though not really unless noise frightens you

not even gonna take them time to take a pic of the dyno, but if someone really wants to see it I will but I'm just not happy enough to put it up right now.

Peace
