Hi John,
I have just been reading bits and pieces of your concern with power output. I haven't had much Just Commodores time lately, so I do not know the full storey.
I do agree that that your 123rwkw is certainly on the low end of the power table. (I assume that the dyno was a Dyno Dynamics or Mainline unit). It should be noted that all Dyno's will give slightly different readings due to a range of variables however, thats another matter).
I also agree that the LPG could be holding down the power @ Wide Open Throttle. Many mixers for standard fit ups are probably marginal, most will struggle with gas flow at WOT demand. Also, if you have a power robbing gas ring in the induction pipe, there is another restriction to be accounted for. Did the engine surge on the dyno at WOT, or was a lean condition noted??? Just throwing in some observations etc.
Is is possible to give a run on Petrol for back to back comparisons, this will certainly tell the storey??A few years ago I carried out back to back comparisons on a VR V6 Commodore. At WOT there was a small power drop when run on LPG however, it was barely noticable on road.
Also, I have learn't from my experience with the Ecotec V6 that a check on the valve timing (cam degreeing) is abosolutely critical upon camshaft installation. I have noted that most camshafts which are fitted @ zero degrees (Factory dots aligned) will not make power. I gained this info from Crow Cams who stress that cam timing must be right with the Holden V6.
Was the camshaft you installed degreed as per the cam card????????
John, I built an Ecotec V6 last year and achieved good results with basic modes. 133 approx rwkw. As part of this build I posted the results on a personal web site:
My Street Car (Which is soon to be decommisioned). Before it goes, perhaps you may like to check out the Stage One engine build. Perhaps there may be some further info that will help you with your build up.
Good luck
