Dyno numbers d15b7!!!! disapointed.
well,
I can only sigh on this one. First I lost to my buddy gay *** vr6 gti. Today I took my car to the dyno for the hell of it, not expecting too much or nuthin but at least put down some decent numbers. well this is how it went, the setup is
d15b7
greddy mni
garrett t3 42/48 ar.
2 inch charge pipes
2 1/2 dp no cat
starion front mount
dsm bov
12:1 fmu
inline pump
I wanna post the pics and the chart but i'm an idiot, don't know how,
it's odd that my tourque is greater than my peak hp. another thing is after 4k my boost goes down to about fiv until redline, is that normal or I gotten too rich on the top end and lost power therefore my torbo lost steam by 4.5k? if u guys can help me read this chart and expalin to me whats the deal is.but here's the link

Re:Dyno numbers d15b7!!!! disapointed.
hey!
thanks man for posting it. I appreciate it. I dunno man this is my first time on a dyno, i don't really know what to expect out of this setup. I'm down to a couple of reasons why it lost it's steam, one, gotten to rich or i'm leaking boost somewere which shouldn't happen if it did won't the home depot couplers pop off? well anyway feel free to help me explain this, i feel bad to show all you HMT members this awful dyno chart, but feel free to critique and explain what happened. thanks again for posting these pics again

Re:Dyno numbers d15b7!!!! disapointed.
I think your turbo is not to blame. You need better management. Your A/F is pig rich after 5-5.5 which is killing you. A 10:1 might help, but it's not going to bring a smile to your face.

Re:Dyno numbers d15b7!!!! disapointed.
Yeah, you can see it clear as day... once your a/f ratio goes below 11:1, it's downhill from there. It's almost definatley a way overfueling problem. It may need some more timing too. That tubo tops out around 300hp according to the compressor maps, back when I was researching them, and I'll tell you, I run teh same one on my d16z6. It's much bigger than the greddy turbo, and I know that's good for like 250~275 @ like 15~16psi. There's a major fueling problem there. Look into the afc hack.
