Misfires were related to the tune, not OCC...AFR imbalance I was seeing WAS related to a restrictive RR OCC as it went away immediately after I removed the RR OCC...
Here's some info straight from fluid dynamic on impact of longer tubing, same diameter:
In terms of air flow through a tube and a changing length here's a GREAT reference:
http://www.newton.dep.anl.gov/askasc...9/eng99525.htm
If you go through it you'll easily see that length of tube directly impacts air flow and resistence and does so significantly...
In our case, tube is being extended from about say 5 inches to say 5-6 feet so about 15 times longer than stock. On top of that add the immediate bends at the PCV outlet and you'll quickly see where I'm coming from here...and then what about the baffle inside the can and details on flow there and how that impacts much needed vacuum coming from the other side (rear intake tube)
You keep mentioning 525whp and nitrous and running it for a long time and I know you're not putting milage on that car or racing it for extended periods of time as you've said this yourself. That sort of feedback on this topic is really inappropriate.. |
Dzenno, I have been your friend on here for a while, but your statements as of late are really lacking tact and quite rude. You are making tons of assumptions with no data whatsoever. This is no different than when people used to say you would blow the tranny at more than 350 rwtq or 14 psi of boost. I had a theory about whether a DCI or CAI would give noticeable IAT gains and didn't get on this forum throwing around theory. I datalogged a ton on my own time and posted legitimate scientific data. Until I see facts, this is nothing more than speculation. I am sorry that makes you angry to the point that you say my feedback is inappropriate, but you have not a single ounce of data at this point to support anything you are saying. I would
love to see data and would support any of the findings.
The fact remains that I have run probably 8-10 bottles through my car at about 525 rwhp and never once had a misfire with my OCC.
