Well Here is my setup first
B18B
T3/T04E .63 ar/ 54 trim compressor
Zdyne Gold SECU 450 CC injectors
Drag FMIC
2.5 inch exhaust + dp No cat
open loop tial wastegate

best run at 8 psi was 189 HP/155 ft/lbs tq
I was hoping for more power but A/F was aready really lean if not too lean (13:1-14:1)
Don't know why I am not making anymore power then that but I think I would like to build the engine so I can run 15 psi I think then I would be getting better use out of the turbo
Also the head needs to be opend up to make more power. I a pic of the dyno plot but I don't know how to post it.

when do u hit full boost w/ that turbo? do u have stock rev limit?

89civic1.8T

Fulll boost it around 3000 rpms but the power takes abit to kick in. The rev limit is stock

FAST94GSR

hmm seems a little low to me, but i could be wrong.

That is amazingly low. If you running really lean you should have been making more power than rich.

my b18b at 14psi makes 303whp 234 ft lbs w/ 160k

VaporTrail

that is really lean. Power will come up with more fuel

How? What kinda A/F ratio's are you running to run that much boost? Any thing done to strengthen the block?

What A/F should I see? 11:1 or 12:1?
Also right now I can't run any higher then 8-10 psi because I still have the stock map sensor. Once I get a 3 bar I can try running 12-15 psi.

TurboSedan

I think a safe yet powerful A/F ratio is 12.5:1. It will take some tuning to get there but I think that is about where you should shoot for.

What kind of dyno was it on? That was pretty lean though...

b18bvudoo

thats pretty low for full boost for yor turbo specs. u sure it doesnt start spooling at 3k instead? sounds like it if you say it takes a bit for power to kick in. reason i ask is cuz i have a smaller compressor t04b and i start spooling at 2900 and hit full boost at 3800.

HybridHatchC1

you sould be aleast in the low 200 range with 8lbs and that setup. somthing is terribly wrong. **** my Sohc ghetto setup makes 186whp at 9lbs

GokuSSJ4

thats low ...
good ?? what type of dyno too?

intekragsr

i got the same turbo and I wish it hit full boost at 3000 rpm.

HXMan

Maybe it is a Mustang Dyno??

89civic1.8T

It was a Mustang dyno.
And I get boost so early is because My turbine is a standered or a stage II wheel. Not a stage III like the rest of you luckey ones.

SlowB16

Dont Mustang Dyno's give low hp numbers?

Etylorcen

Yeah they do...so that makes sense. Lets see the dyno.

89civic1.8T

I have a picture I took of the dyno plot. It's a large file but If someone could host it for me I could post it. Ecomplanet isn't working for me to upload it.

iTrader: (1)

1) that is a mustang dyno, its gonna be low

2) u r way too lean. try to get it around 12:1. boost loves fuel.

3)that stage 2 wheel is really holding u back.
