Turdle · April 25, 2017

I'm going to throw the Turbo word in again. I think you are going down a rough road while stressing the front of your 2 bolt main block.

Just my .02. Going back under my blanky now.

vroomzoomboom · April 25, 2017

i have a feeling the 2 bolt main block will end up being a 2 bolt slant 4 cylinder. even more so if i get my hands on a m122 and make the intake i want to. the turbo thing has crossed my mind a few times. looking at the headache that don had making everything work in his truck shies me away a little bit. he did tons of research to. for a dummy like me, a supercharger is the only way to add speed.....plus the sound of a screaming supercharger at full throttle puts a smile on anyone's face lol. its also easier to hid when a punk in a vet rolls up along side you. i can hear dons turbo under no load a block from my house lol.
i have talked to ron at damper dudes on the phone and emails. once again he has said he can repair the one i have, but he is also going to see what he can do for a performance one as well. i boxed it up tonight with the smaller pulley (he wanted one to make sure everything fits i guess) and have sent it on its way. i am also still thinking of pulling the motor and popping a few mains off just to make sure the bearings are still ok. that and i can fix my leaking pan that drives me nuts.
all this and having to work on the kids truck (put a stereo in it last night for him, now the cats are clogged, has zero power and cant rev in neutral past 2500 even) as well as i am going to do a rear diff swap because it has a pinion bearing going bad.

I was thinking of staying with the stock sized crank pulley so that the rest of the accessories don't get over sped too. I'm also fairly certain that at 6,000 rpms the blower is turning it's maximum rated rpms, if not more than that already (it has been a while since I ran the math on it).

I hope those "clogged cats" aren't a jumped timing chain. We recently had that on a 2012 F150 with the new 3.7L V6 at work.

This is a REALLY nice truck! Great job on everything. I am constantly changing mine up too. One of the things on my short list is a blower, not the Eaton but a Procharger or Paxton setup. Keep up the good work.

thanks eh!

so i got a email from ron at damper dudes

I received your balancer.... looking at it revels it is the same dimensions as the explorer balancer ....that would be the easiest fix as they are available in street performance and SFI race applications. not having any luck to find a bolt on pulley balancer such as yours to accept the reluctor wheel ( hubs don't extend back far enough) to install a wheel on....

gave him a call. long story short, i told him to repair mine and send it back up, then have a hard look for what can be done for a performance one. if it ends up being a *****, i will have to bite the bullet and tell him to make me a larger diameter pulley'd explorer one (even thought i would like to stick to one i can change pulleys).
i also asked him how much the old one slipped.....ready for it?
180 degrees....ouch. surprised it even ran.

CDW6212R · May 2, 2017

Thanks for the details on the balancer, hopefully that source will be able to put one together for you long term. I hope your engine is fine too.

I wonder what balance the Aussie 347's are that they run in their cars, 28oz or 50oz? Plus I wonder what a ring of steel would weigh to weld to the back of an SFI balancer, to mount a trigger wheel. Most of the pictures of various brands show a weight right where the trigger wheel needs to go, that's hard to attach to.

Dono · May 2, 2017

Maybe the counter balance just kept spinning.
That would explain why the shake seemed to get better for a bit.

lol

its funny, but i think you have a valid point! lol

vroomzoomboom · May 11, 2017

balancer came back today. ran right to the post office....and paid the duty on a part i already own....what a scam.
so bolted it on, put everything back together, and it now started leaking antifreeze. don's luck with his truck flashed through my mind. turned out i didnt have one bolt going to the t stat housing tight enough. started it up (which im sure the neighbours wished spring wasnt here). felt a little shake. dont think i can do anything with that if 5 and 8 are acting funny at idle. wished i knew if there was a fix for that to. so i took it for its first wash since october. night and day difference. my fillings dont rattle out of my head driving it now! YAY! i do however have a high idle issue. i think either a line came off when i changed the mounts, or a broke a brass fitting. will get my hands on buddys smoker again and smoke the motor. that will happen hopefully saturday. because tomorrow this lucky guy gets to change the rear axle on the kids sport....

Dono · May 12, 2017

Great news!
And... whenever Lasota is done, we get to play.
Your going to me start leaning out the idle and see if it helps.

I think cammed motors don't read accurately at the 02's idling at low air speed. Let's try it.

My motor seemed to be responding pretty good to it, and it was slowly removing that terrible smell from the exhaust at idle.

ahodges · May 12, 2017

Don, I don't think cammed motors read accurately at idle either. When mine idles, the wideband fluctuates all over (between 13.5 and 15).

Dono · May 12, 2017

Thanks Andrew. This helps.
I'll be interested to lean out Evil's idle. Both our trucks really kinda stink when idling. The smell seemed to get less as I leaned idle rpm, extremely low load on mine. I'll try pulling 3% to start with and we will see how evil responds. Since my trucks still broken, at least I'll be able to play around with Evil's tune and learn what works (and what doesn't).
There are some things that just require playing around with to get the over all manners civilized.

Psst, that's the cats, without them it can't make that rotten smell.

Good to hear Tim, hopefully that one will stay together for years.

Dono · May 12, 2017

Cats? what cats? we can't see any cats. Just a rich idle.
Evil hates idling, He hunts for an idle as soon as you bring idle down to an area that he doesn't like.
Put the truck when in gear and he pulls on a non-hunting idle, to low and he hunts for an idle. My truck doesn't like to start unless its within a couple of percent of its own 'ideal' startup enrichment. very frustrating. Both have their own personality. I thought an expert like Don Lasota would have some magic dust here, but there isn't any. Its trial and error. were trying to make our modified motors behave like a perfect factory fresh vehicle, and its a challenge.

Hopefully we have a better year this summer with this stuff.

Centaurus5.0 · May 13, 2017

Has adaptive learning been disabled in the PCM?

Dono · May 13, 2017

We disable it for tuning, then turn it back on when we have the part throttle, closed loop stuff dialed in using the front o2 sensors.
With adaptive learning turned on, the long term fuel trims (LTFT) start adjusting, and that's really the adaptive learning.

vroomzoomboom · May 14, 2017

you'll have some stuff to touch on for me don. remember when i was telling you sometimes it would buck? well....
also smoked the motor today. found leaks around the throttle body gasket, which is kinda odd because when ever i take the intake tube off, i never touch anything on the throttle body at all. i pulled the intake tube off and re smoked the motor. could see anything (but that has happen in the past when i couldnt see anything and there was a leak). made some new gaskets for the intake tube on both ends, and smoked the motor again. this time nothing came out. took it for a small ride tonight. idle is still a little high but better.
also did the diff in the kids truck last night. was talking to gmanpaint about how to go about the brake system on it. he did recommend taking the hard line off where it and the rubber line meet. sorry greg, but i went against your advise. but it did work out pretty good however. diff swap in 4 hours. that wasnt busting ass, and that was also showing the kid on how to do this and that. finished that up, and took it for a drive. all good.
as we were driving his truck i turn to him and say "see! no more bearing noise!:
him "honestly, it never really bothered me"
me ".........."
kids

Dono · May 14, 2017

Lol. yea, at least he's interested. he also now knows what that noise is.
Great to hear the smoke test helped find leaks. doesn't matter why they were there, just that you found them and fixed em.

We will work at the problem areas that are going to take some trial and error. some of it will just mean copying stuff from tuning that we had done together over to your new tune. Don Lasota is very good at what he does, and its great to hear that some adjustments are not easy to nail down.

Lets hope we can lower the idle and not end up with hat crazy hunting idle we couldn't resolve before.

vroomzoomboom · May 21, 2017

its the long weekend here, as well as it has been super nice out now. i've had a high idle issue for a while with evil (like 1400-1500 rpm high). thought it might be in the tune. lasota sent a file but it didnt work. i also had a problem with the injectors shutting off while cruising, he did for the most fix that, said that i had to remember, with basically a racing engine being driven on the street, i am going to find some glitches. dono swapped the trans tune over for me as well. but this high idle thing drove me nuts. it wasnt real drivable. i mentioned it to dono as well. i brought up that the throttle plate looked a little too open to me. dono suggested trying to back it off. i was worried about it messing with the tune because it will also affect the voltage on the tps. his easy solution, adjust the tps after i adjust the plate... duh, brain fart on my part. so i was outside until about 10 or so with flashlight in hand trying to get it just right. got it, and even somehow found .2 volts at WOT. i didnt want to start it because it was late, and i like my neighbours and i want to keep them liking me lol. came home friday, went to start it...wont start. wonderful. i spent the next four hours checking fuses, probing this that that because i had no power going in or coming out of the tps. the problem? the 5v ref wire going into the connector somehow broke inside but the cover didnt. i was happy and pissed off at the same time.
pulled a connector of one of my parts trucks, soldered it in, good to go. or once again, so i thought. set the volts to .98 closed, but when i would go WOT, and let it go, it would rest at 1.2 volts. because i messed with the tps to get adjustment from it, it was binding on my throttle body (accufab which takes a 96-97 explorer tps no problem, but 98 and up, you have to do a little tinkering. surprise.).

so i made up a little spacer to go between the throttle body, and tps.

dont mind my red neck paint bake booth.
idle is now back to pretty much where it should be. took it for a drive tonight down the highway for about a hour. bad new, she does still have a good vibration to it. so when i get a chance because i have been pretty busy lately, i think i am going to pull the motor and have it re balanced. i am also going to ask how hard it would be to zero balance it, that way i wont ever have to worry about the weight ever spinning like it did before on the balancer.

CDW6212R · May 21, 2017

That's making progress, keep working with it, you'll get it right. I don't know what to say for the vibration, if it is the balance that would mean something is way off(wrong flexplate(50oz)) etc, and I doubt that could be the answer. I'd go at the engine only if nothing still can be figured out(I know you are basically there now).

Thanks for the TPS tip, I didn't know the 96/97 was any different than the 98-01 part.
