(02-06-2015, 11:48 PM)MTUPower 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.
More testing, videos and minor tweaks to come soon...
This is very encouraging, and great news. Thank you for posting your results! Now you just need to get rid of that ancient paddlewheel - uh, I mean - stock turbo
I'll be drilling and reaming mine soon hopefully. Although I won't be able to drive the car for another couple months (snow). My plan will be a 25% enlargement of all holes. Already starting with the "uprated" '85 prechambers with the larger injector hole and lower seat.
