i have pictures, ill get them up tonight.
Well I think I pretty much damaged my rear running it dry. I'm pretty sure the bearings are bad, maybe even the ring gear and that's most of my power loss. cause this isn't cool: http://www.boostedmiata.com/dynos/in...ld_compare.jpg |
here's the rest of them:

how much boost for those pulls would be nice.
|
third gen, how much boost are you running?
|
he peaked at 11.5psi and then it dropped the 9.5psi by redline, IIRC.
|
Mine peaked around 8.5psi, dropped pretty fast after 5500 or so. Damn AFM.

So I uploaded my datalogs as I datalogged every dyno pull I made on Saturday. I did 3 pulls. The first datalog, I peak at 11.9psi at 5276 RPM and I let off at 6833 RPM where I dropped to 9.7psi. Second dyno, I peak at 5147 RPM where I hit 12 psi. Why does my boost fall off like this?
P.S. I just today upgraded my stock 2" midpipe with a resonator, to a 2.5" no cat no resonator midpipe. So now my entire exhaust is 2.5". Hopefully this should help me out a little. Hey Brain, what's up with those easytherm values?Attachment 11624 Attachment 11625 Attachment 11626 |

What's with you guys running filters right off the compressor housing? I've seen a turbo car drop almost 30 whp on the dyno when moving the filter from a cooler location to right off the compressor housing. This was an 800 whp car, but the the negative effects are noticeable and should still be on cars making 1/4 the power.

Frank Hell, our first dyno day in DE there was a 700+ hp mustang that gained like 50-70hp by removing his filter altogether. |

Frank We removed the filter for my second pull and gained/lost nothing. So that "tiny" filter is more than big enough for the particular setup/tune. |
Tim took off his filter on his 3rd run and saw little to no difference.
