Speakers can be a good way to test ignitor polarity sometimes. Just make sure that the cone doesn't extend too far because it'll snap back and cause erronious readings. http://www.geocities.com/cd23c/test.html



Can you post a link to your sound clip(s)? I'll post a link to the sound clips of my 20B. Massive vacuum leaks and terrible AF mixtures asside, it's what an unmuffled 20B with DLIDFIS-style direct fire (spaced 120º apart) sounds like (better known as TLIDFIS hehe). I'll make some new clips when the manifold is finished.

clip 2

Nope, I sure don't. I don't even have any clips of any of my two rotor engines.

this should start the download of the only clip I have at the moment



84 12A Exhaust



just a bunch of idling a few revs...altho I didn't let off the gas fully on the second rev...need to make another recording of me letting it off at around 7-8k so you can hear the thing go BOOOOOOOOOOOOOOOOOM aaaaaaaaa ha ha ha



I'll see what I can do tomorrow...need to take it out for a spin anyway...washed out the engine bay...and I want to make sure that nothing important is going to not be working...er...uhm...perhaps I just like going on "test drives"

Jeff20B

Yep, your exhaust has the old style sound to it.

blown 83

That 20B sounds sick......uuuuuhhhhhhhhhhhh, I mean sick in the really bad *** kind of way. Mad props to you on the 20B.

Jeff20B

Thanks. Check out your SC thread.

Alright...I have NOTHING to do today...so I'm heading to town to buy all of this crap that I need to do this...heck...I might have it all wired up and ready before the day is over



Then I can have a really good recording of the difference in stock and direct fire on a 12A



got my list...and i'm headin to town...be back later

Jeff20B

Cool!

alllright...I got most of what I need here now

About to go start fabrication of the igniter plate in a few mins...ehm...lets see



I'm not TOTALLY sure what i'm going to do with the leading coils...I will have to move them somewhere closer to the plugs...so I've got this hair brained idea to fab a plate out of that alluminum and use the top piece that normally holds the coils...thread it into the plate or something...ah...I'll go look at it...still not totally sure how to go about doing this...but I'll find something



I got two of the 3 GM ignitors...which look just like the HEI...not sure if they are...but I doubt there are a lot of them that look the same...of course they can't seem to find me two parts with the same numbers...but thats how it goes with the parts game



I'm hoping the one I ordered will match one of these two that I have here...if not im gonna be pissed...they look identical really...just diff numbers...probably no big deal



got some 99.9% pure micronized silver thermal paste around here somewhere that I use on computer CPU's...i'll stick some of that on the ignitors before I put them on the heat sink...ehmmm....



got another borg warner coil...like the other...I think...but I don't remember it being made in america...guess it could have slipped my mind tho



ahm...and a bracket for it...a solid metal "mr gasket" universal coil cover...also has the mounting brakcet with it...not just a cover...i'll mount the trailing coil into that



mmm...bunch of connectors...mostly for 10-12 guage...but some smaller for the other wires



and 3 20 foot coils of 10guage oil/gas resistant braided wire...green cuz they didn't have red...black...and white



I think i'll use the black for hot...white for negative...green for ground...i'm the only one that works on it anyway...so no biggie



also some XLR mic cable from the music shop...which he tested for me...for carrying the ignitor signal



alright...going outside to work on the heat sink (s)...should have the ignitor tomorrow...so i'm hoping to have it up by friday...i'll record another exhaust clip before I do...and another after

falcoln0014

OH OH OH...i came up with a GREAT idea for the leading coils...i stole the factory coil holder off my parts car...and I'm going to modify it a tad...and mount it down where the ac pump used to be...then mount the trailing in the stock spot with a dummy coil in the other



this is gonna be sooooo cool when it done



got the heatsink marked...now i'm heading out to cut it...then drill all the holes in it
