Finally got my car to dynotest center for some tuning. Everything was great there and we got pretty nice numbers, best run was 445,9whp but there were little knock so we had to pull back timing a bit, so final numbers were 426,9whp ja 479,1NM . We only had one hour so next time we'll hopefully get a'bit better numbers

here's a videoclip from dyno


Power curve looks nice I think

 

did any of you guys test how it affects if you steer bypass air back to pipes?

 

Solid power band, should be a fun whip out there. What octane gas/petrol do you have out there? and what psi? You talking about recirculated BOV's (if so what's the concern)?

 

yep thats what im talking about... My car starts rough idle when moving and I hit the clutch, my tuner said that it may be cause I'm shooting air to atmosphere. Might be a intake leak also but I haven't found it, not even with smoke tester. We have 99/98 octane gas here.

 

Ah my setup is a little different without recirculated BOV's (the just vent to atmosphere). I have been waiting on GTM To ship me the external waste gate conversion kit which would recirculate back to the exhaust for external tial wastegates but haven't received that yet. I do have the stock actuators which do recirculate the excess boost to the exhaust and don't have any issues there with the symptoms you are reporting.

I'm not aware of anyone on the board running recirculated BOV's.

I know back in the day there used to be some issues with idle dropping really low pressing the clutch in if there was a very light flywheel which we used to fix by drilling a very small hole in the throttle plate back on the VQ35DE's but I currently run stock flywheel on my setup without that issue on the HR.

Maybe someone else can chime in with more info.

 

well there has been misunderstandings. First my bypass blows to atmostphere and I'm running GTM supercharger stg1 I was thinking if it helps if I blow air back to intake pipes...
