It's frigging ridiculous for that round here sometimes...

The other year, I wanted to give it a long run below but close to 2000 rpm to seal up valve seals with an additive because the etest was due NOW, couldn't wait a week or two for normal use to do it. Anyway, so 2000rpm being around 40mph, too fast for the city, too slow for the highway, so I was driving round the back roads, at 10 under the limit, just trying to stay out of everyones way... and a bored cop finds me... was there for half an hour and he just wasn't getting it..."I know you're up to something but I can't figure out what" :rolleyes: then thankfully he got an urgent call

Previously I installed a longer cable from some sort of 4 cylinder dodge but even after installing the cable holder closer to the throttle cam by drilling new holes, it would kink something fierce. Now I have OEM cable feel. The progressive cam I did this time is extremely progressive. Should give me great throttle control down low and past 50% it will go WOT very quickly.

Utah had amazing huge empty roads all over the place. In Seattle I am surrounded by 25mph roads that are packed with cars or are residential/potential pedestrians. There are some big open roads but they are just main roads that few people drive on that cops love to watch because the lack of traffic = more speeding tickets. Hard to give tickets in traffic. I can find big roads farther away but its hard to get away from people. The freeway? Forget about it :(
Re: The Holset he341 3.0L
realistically what do you think that the stock or stock replacement pistons (kb silvolite for exc.) would tolerate for boost in a daily driver while maintaining a good degree of reliability? about at what point would a set of custom forged pistons make the most sense for someone wanting to boost a 3L.
Re: The Holset he341 3.0L
Its hard to say on things like that. Ring gap matters, fuel/spark tune matters, fuel octane matters. How you drive it matters. How much power you make at a certain boost level matters. Boost will make different power on each setup per psi. It can also be that too much torque from a quick spooling turbo can hurt things sooner, and also probably indicate a setup that will get "whooped on" a little more.
It could be 8 psi, it could be 15. Could be more. Megasquirt definitely raises the safety levels.

Missing on a few cylinders. Need to pull the plugs and potentially the oil pan to check bearings :( Sounds can be hard to verify when you are not on all cylinders. Going to be pissed if it spun a bearing.
Re: The Holset he341 3.0L
Sounds like it's missing compression on a few cylinders....
Re: The Holset he341 3.0L
Good point. It seemed too quiet when it turned over with nothing firing. Guess I should do a compression test when I check the plugs. The valve lash was running fine when the heads were installed on the the duster but it is set really tight....Or it managed to jump some teeth on the belt.
Re: The Holset he341 3.0L
120-150psi in all cylinders with rings unseated. So no huge problems...but....
Yay, all 6 plugs are fouled. They are recessed tip NGK 9's so they are pretty darn cold, and they are gapped at .025" from my race car. I did a straight head swap and I guess leaving the plugs in on a fresh rebuild was not a great idea with all that oil and a tough first start.
Re: The Holset he341 3.0L
HOLY CRAP!! 9's!!! Yeah, get some 6's in there AT LEAST with projector tips. I like to file half of the ground strap so more of the electrode is showing (just like a race plug, but WAY cheaper!). I'd also start with .030 gap, but that's me...
Re: The Holset he341 3.0L
Gotta regap a cut back plug every 10-20,000 or so on my N/A 3.0 due to gap erosion, (with 15* base timing) can't imagine how quickly a boosted motor would eat them. (Those were a stock range champion)
Re: The Holset he341 3.0L
I put in some stock range champions that were already gapped at .038"
Apaprently she was actually super lean. All the crazy mods that I did to the regulator to try to deal with twin external pumps meant I was too lean.
Went and seated the rings. She is a bad B. That Semi brake kit spring opens the moment I get over 30% throttle and starts screaming. Sounds very cool, even if I am going very slow. The tune is obviously fubared and the Innovative MTX-L I have is not installed yet. I think its dumping fuel when it gets to 0psi boost because of the way the RRR is setup (point of onset, etc) so its running rich, then above 5000 rpms it rips. Its possible that above 5000 rpms it actually builds a few psi from boost creep or something. No boost gauge installed yet either.
So while its not fast, it is freakin loud. Never heard anything like this before because I can get the wastegate to scream withhout needing to make a lot of noise out the exhaust. It sorta sounds like a garden hose that is coughing on an air bubble...of fire.
Bad news, it overheated in the driveway when I got home. Radiator fan was unplugged but I never stopped for it to be overheating. There was water vaporizing on my radiator so i don't know if it has a leak or if that was from the overflow. The radiator sat outside for a long time and could have gotten damaged in a way that was not evident until driving. I need to check the thermostat in case that failed during the uber corrosion that was happening on the bad headgasket.
For me its a generally good day. I got to drive a holset 3.0 and make lots of noise.
The holset still has the silencer ring in it.
Re: The Holset he341 3.0L
Bent your going to have to bring her up to Misson (2hour drive)for a week end and let her loose .

My last rad failed from the outside inwards, I was getting indications of seep like that, but it still seemed to be holding enough pressure... I thought, hmmm, maybe I'll hose the fins out... hit 'em with the hose and the damn things ended up all over the engine bay.... the fins were rotted out completely, or the few that weren't were making contact by rust, not a terribly good conductor. So yours could be going the same way if it was sitting round outside.
Re: The Holset he341 3.0L
Well since everything was rotting out from that nasty coolant that I couldn't keep clean, i was thinking its probably rotted from the inside out.
I have already destroyed 1 thermostat in the Spirit a few years ago. Corroded, fell apart, had to pull over. I didn't take the hint since nobody believed it was the headgasket. You may have even been suggesting an electrical issue instead of the headgasket.
I want to drive it so bad after a terrible day at work but I gotta work on her instead :( I just wanna open that wastegate around town!
Re: The Holset he341 3.0L
Good job getting it up and going again. Why are you running a RRR with MS? That seems like it would be much harder to predict a tune since your injector tip pressure would be changing.

He traded in his brass balls for crystal ones. :D

Put a 180 stat in and actually plugged the radiator fan in :P Overheating situation gone. Easy to overheat 100% water with no radiator fan.
The bad thing is on my way back it sounds like something is rattiling bad in the top end. Maybe a rocker got loose.

This is not "getting it going." This is my daily driver. I just stole the turbo parts sans turbo off the Duster and installed burned exhaust valve stock heads from my Daily onto the Duster and took its good stock heads that had a big cam and solid rockers installed in. My daily 3.0 has had a leaking headgasket for 5 years and a slowly burning exhaust valve or 2. The headgasket finally started leaking water back into the cylinders and that forced repair. That only happened after 3600 miles of driving with 1800 of that towing another vehicle.
The proper cylinder head for the Duster will go back on eventually, she is just n/a for now with megasquirt until I build a new setup.

Dam i love how it sounds.

and the silencer ring is still installed. I might keep it installed. Will probably sound a little better when I fix the exhaust leak at the V band (not mating up right) and have it tuned properly. I took out the point of onset setting and it drove worse. Need to get my gauges done and installed. This is the reason I put the zero psi spring in there, so I could try to drive around without booming it up.
Its also pretty quiet. Catless 3" with ultraflow. I think it would be a lot quieter if I got that stupid v band clamping right. Gonna have to take off the downpipe and hack and weld.

Does not compute. It's either going or its not, eh?
Hope the valvetrain is alright. Replacing one of those rockers is a lot more effort than replacing a stocker.

Ahhh.....that makes more sense. I thought you were getting things back on the Duster.......but if I would have thought about it for more than 2 seconds I would have noticed all the pics weren't of a Duster at all.
