As things have settled down a little and having decided to put aside my next engine upgrade for a while I thought I might do some low-budget tinkering.
Besides finishing up the sound inside (like soldering the new pioneer head-unit + speakers I bought 1,5 years ago...), I thought I might tweak the sound outside too and perhaps gain a few horsies while I'm at it. :trumpet:
That's to say: the dyno operator of my most recent, rather disappointing dyno run (205rwhp/305rwtq) said the reverse flows I'm using are way too restrictive. :crap:
Though I do have the cash for some max-flows or STS baffles, I'd like to play with these reverse flows first. :bounce:
I was told I could drill holes to improve flow and sound. How does this work? Would drilling front and endcap suffice or are there baffles in between to drill too?
Edit: Should the carb/timing be readjusted after drilling the holes?

)... now if this blasted thunderstorm would pass I could actually get something done today. :shocking:
