No, but we are very close to trying that.
I'll report as soon as it happens, win, lose, or draw....
I'm really excited about it!!!!
Just a lot of details to nail down, first...:violent1:
Thanks a lot for your interest!:cheers:
Well, we have been busy with this thing, for sure and have made some sideways progress, but are not there, yet.
I say "sideways" because I cant say, for sure, that we have been going forward... Here's why:
We started out testing our air/fuel mixture with an F.A.S.T. wideband, data-logging, hand-held meter, and it hs been very helpful in terms of telling us what the mixture is doing at any particular time.
Carb #1 was a blow-thru 750 Holley DP with a boost-referenced power valve, and in testing, trying to get the mixture under control using normal means (installing richer jets all the way around and we could never, after several tries, get close to our desired 11.5:1 A/F ratio under boost... it would get down to about 16:1 and that is not a useable ratio,
As an experiment, I replaced that carb with carburator #2 (a nearly-identical 750 Holley double pumper that I use on my Vortech-blown 360 Magnum) and did some A/F ratio testing with it, just to see if I could get ratios anywhere near what I needed with it.
After three tries, all with bigger jets than the previous attempts, I was close, but not there, yet.
My friend Aaron has been suggesting that I install some float bowl, vent tube extensions made from 5/16" brake tubing, running them all the way to the entrance of the carb hat. I decided to try them, but was also told that the high speed air bleeds could be totally blocked with round toothpicks, broken off leaving about 1/4" sticking out for retrieval, later, if it didn't work.
I did the stupid thing; I made two changes at the same time (I was tired of working on this thing, trying to fatten it up.)
The next test-run yielded figures that were TOO rich (10;1 to 10.5:1 on the meter. Now, when it gets into boost (8+ pounds max,) it staarts missing, badly.
I have a new distributor, new cap and rotor, new Taylor cable wires, new NGK supercharger (non-extended nose) cold plugs gapped at .030" and a Mopar performance Orange box with a stock coil.
I own a new MSD 6-AL II and a Blaster II coil.
I think the time has come to install all that MSD stuff, and pull the toothpicks out of the high speed air bleeds. I only used the toothpicks on the back 2 barrels. The front ones remain open.
Maybe that will get me the 11.5:1 A/F ratio I am looking for and stop the ignition "missing under boost."
The Snowperformance Boost Cooler has a #3 jet in it (small) and is set to come on at 5 pounds of boost. I don't think that was a problem because the engine started missing before the spray began, I use pure meth in that reservoir; no water..
So that's my story and I'm stickin; to it!
Goin' into the hospital Monday morning at 8, and will emerge on Wednesday afternoon. Heart issues...
This "missing under boost" issue is killing me!!!:banghead:
