2003 wrx. Full cobra 3inch decat,k&n panel filter,perrin inlet pipe,prodrive y pipe and mapped on carrberry rom. |
Firstly, why is the torque/bhp shown crossing at 4600rpm when it has to be 5252rpm?
What turbo? I'm presuming not a TD04 as the peak toque is late in the rev range. What's the reason for the dip in power after peak torque? Then it picks up again later on. I would have expected the power to continue to rise to around 340bph. Also, that graph suggest that about 3mm is the difference between 290 and 340 - what scale is it? Do you have some better images/graphs? |

I'm guessing boost control not held.

Good numbers but can't say much about the graph with the scale being so far off.

Would a 3 port boost solenoid and a tweak to suit iron the curve out abit? Like i say car drives spot on.
|
I would have fitted one for sure.

Also, the dyno sheet above is 11 years old, do you have a more up to date one? |
11years? The dyno was done this morning

See what u mean. Operator must of made a typo lol it says 2006,05,17 should be 06,05,17

Better control of boost at high revs, especially when run boost above stock. With the 2-port, you are likely to experience a drop off in boost after 5k or an oscillation. As per the graph.
|
Hence I said boost control not held.
|
290/340 on a 2.0?
|
3 ports aren't that expensive either

Its peaking at 22.7psi aswell so running good boost on a td04. That from my psi3 data monitor so accurate.

Ive got a print out from scoobyclinic from 2months prior to me owning car and it made 273bhp. That was before perrin inlet pipe and i had it mapped on carrberry rom. The difference when carrberry rom was mapped onto it is night and day.

What was the torque on the clinic graph?
