i went on the dyno today
I dyno'ed tuned my car today myself on a dyno, becous there aren't any good tuners here in the Netherlands. Could you guys analise it for me
Here is the dyno
Fist line is on 10psi street tuned 2line is on 17psi tuned on the dyno
and its flywheel hp
This is my setup
B16a build bottem end(stocksleeves)
Stock b16a1 head
itr IM and TB
T3/T4 57 trim .63a/r
apexi gt core intercooler
dynamic autosport mani
hks waste hks blow
2,25inch downpipe(it will be replaced for "3)
2inch to 2,25inch intercoolerpiping (it wil also be replaced)
rc 550cc
My a/f is 12,5 in boost
and my ingnition is retated 0,6per lbs of boost
its 15,25@9000rpm @18psi and it looks good this is how
i made the most power. Egt was good also and the plugs lookt great
But What i noticed on the dyno whas that it made goed power till 14-15 psi.
But above that it almost made now more power.

Nice, probably running into that restrictive downpipe is causing back pressue as the HP goes up. Still nice numbers

ditch that downpipe and you wiil gain some hp, and what kinda exhaust are you running?? and just to be safe i would have the a/f no leaner than 12:1 ,

Re: (JDM S1eeper)
When you look at the line in the dyno. Its very flat between
6500-8000rpm and you can see the torque caves in at the 6500rpm.
Is this al normal????
and would other cams like gsr cams help to overcome this
thanks Jose

Re: (Mag00n)
exactly his point.. the 'positive' reactions are great... but he opened this topic because the dyno isn't looking that good.. the main question is, I think... will a larger chargepipe and downpipe be the first thing to do... or should he also get the gsr cams installed, or........................

I think you've got some boost creep with that 10 psi run. The torque curve is sloped upwards like you see on a centrifugal supercharger. The torque curve for the 17psi run looks right for a turbocharged car.
