5th & 6th ports always open may not be advantageous, but is it DANGEROUS?

5th & 6th ports always open may not be advantageous, but is it DANGEROUS?

I made that subject line nice and long so that maybe (maybe) you wouldn't think I'm a complete idiot asking the same questions again.

I searched and there is tons of discusison on the pros and cons of "wiring" your aux ports open. but I want to know if there are any >risks< to the engine or other components if they're open all the time.

long story short, my aux ports are stuck at about 3/4 of the way open. the car seems to run great, although I do plan on getting down to the LIM soon and cleaning/fixing the sleeves so that I'll have a proper 6PI system... but in the meantime I have to drive; is there any danger from running the aux ports open all the time?

thanks

Not that I know of, many modded n/as aren't even running 5th/6th port sleeves. You should be fine. I ran around with my wired open for a long time with no problems.

I wouldn't think so- mine open way early now with the setup I've got, don't get the 3800 acceleration "bump" anymore, just a smooth transition now, ports open at 3000 or so, secondaries kick in at about 4500 now...it's tripping out the boost sensor, throws a code every time I nail it, but other than that, no probs...I keep thinking it MIGHT be running lean before the secondaries finally kick in, but I see/ hear nothing that would support that...so, long story short, it might take a little longer for your secondaries to kick in...

just thought of something else: if each sleeve is stuck open, but they're not open to exactly the same degree, how does that affect the engine?

it wont hurt anything it just wont be running at peak effeceincy or power. if one is fully open and one is completely closed it could cause a lean condition in the one rotor, since the efi doesnt look at the rotors seperatly, but i doubt it would be an issue.
