I finally got around to dynoing my car after approx. 3 years of boost. It's been 2 years on this motor however.

95 civic hatch dx [completely gutted]
d16y7 block
d16z6 head
arp headstuds
b16 throttle body
greddy turbo mani/turbo
2.5-3' dp/exhaust
jrc 8" i/c
450cc [dsm's]
p28 -> crome pro [tuned my jose bellas of speedworx]
dx tranny
~9psi

1st run


2nd run


3rd run


most cars i saw dynoing made their highest numbers on the last run, apparently mine did not.

i just got a PLX M300 mounted in my car and usb datalogging port on the ecu. im going to raise the boost another psi or 2... keep an eye on the a/f and hopefully retune sometime soon on 12psi.

what do you think? /

i put down identical numbers to your first run on 8 psi with a stock z6, 450's,fmic so I would say your numbers are average. Im surprised you didnt put down a few more horses with the large downpipe,tb, and added cr of the mini-me though. What was the temperature like? it was 100 degrees and very humid when i did mine.

on my first sohc setup stock motor with the greddy kit i put down the same hp numbers but with 10 more lbtq. good numbers

it was really hot and humid (it showered a few times while i waited to dyno)...

it seems my #s are about average so i'm ok. i actually just finished installing an EX/Si transmission, ACT XTSS clutch and Fidanza 7.5lb flywheel. feels freakin' great!!!

next is JG Edelbrock manifold... and a retune.

a few more lbs should get you to about 200, what fuel pump are you running?

My buddy after going NepTune jumped up to 264hp@12psi with greddy kit and 550cc on a Z6..
But he is on the 19c, not the little 15g

My buddy's hatch made 201whp/180wtq yesterday at Lujan as well, 10psi on an Apex'i kit.

Other experiences: stock D16Y8 on a GReddy kit with a 3" exahust, Hondata, tuned my Frank @ SFP- 217whp /186wtq @ 10psi

Same motor (only now 140k miles), another GReddy kit w/ open DP, Uberdata tuned myself, 165whp (don't recall the wtq) @ 5.5psi

Keep in mind, IIRC the Z6 head has a larger combustion chamber and will yield lower compression, that along with the Y8's better IM design is why I typically see Y8's spitting out better numbers than Z6's or atleast Z6 heads.
