prechambers mods?
Well the work is done with the prechamber mods and the end result is just short of "WOW!" I did not change the timing as it was already advanced so there is perhaps some room there for future gains. Now for the report after 40 miles: not as much low end increase as I thought, but there was improvement from idle to 1500 rpm; maybe 5%. It did climb thru the rpm range to get to 2000 RPM measurably faster- and from 2000-3000 the power difference is very noticeable. There was a perhaps 80% decrease in smoke at all rpms except idle where there was and is just a slight bit. That is ultimately important because I have a MYNA pump and it's turned low due to too much smoke for a daily driver when I get on it. Now I can turn the pump up and the car ought to really fly. The 2000+ rpm response is instant and stronger. It really makes a difference at the mid and top end by seeming to breathe freely. The engine is louder and sounds more like a Cummins, but I'm very happy. I certainly cannot say what the long term effect is on enlarging the PC holes, but the short term result is "oh yeah!" I'm going to sleep tonight with a big smile- I think this was a very good mod.
