Darton sleeved at 427ci. should hopefully get on the engine dyno next week and if all is well car should be done soon after. would like to see near 500rwhp na. That’s on a stingy mustang dyno. That thing will be scary fast! Dude, post the progress here! I still need to get mine to the track and see what it'll do. Hope the DR's are worth a crap.

jamtoy Posted June 30, 2022 Share Posted June 30, 2022 Drag radials are on the agenda. I’m now worried about the Georgia heat. I’ll be close to silver dollar dragway where the 2000hp sinks run. 1 Quote Link to comment Share on other sites More sharing options...

I suspect the trans cooler and air to air ProCharger intercooler are blocking a ton of airflow to my radiator. The plan is to get a ZL1 front bumper cover and hood so it can extract more heat out. If that doesn't work, I guess I'll see if I can cram in a larger radiator.... Quote Link to comment Share on other sites More sharing options...

I just remember it was getting hot in traffic and at slower speeds. That was last summer. I've not driven the car in the hotter months this year.

jamtoy Posted August 8, 2022 Share Posted August 8, 2022 I want to drive it to Georgia where I work. Only concern is Atlanta traffic jam on Friday’s. Can the car stay cool and can my left leg handle it. 1 Quote Link to comment Share on other sites More sharing options...

jamtoy Posted August 10, 2022 Share Posted August 10, 2022 Well waiting on shipping co to find a truck. Was hoping to have it by Saturday. If I do get it that biotch will be Georgia bound early Monday morning. 1 Quote Link to comment Share on other sites More sharing options...

JohnC Posted June 26, 2023 Author Share Posted June 26, 2023 Well, fixing some issues I had and just didn't have time to fix. TKR crushed my PS wideband wiring, so redoing that now. It's a PITA to hump over under this dash when my back was already hurting before I started. Changed oil because plug wire came off coil and I assume a lot of e85 got in the oil. Moved starter wire that TKR should have zip tied away from the header it was sitting on. Other O2 sensor on DS was nearly touching the header. Zip tied it away. TKR never plugged a harness in behind my front bumper that I believe went to the side lights. Fixed. Going to discount tire to make them rebalance these Nitto's. Ever since mounted, they get about 70mph and go out of balance. I've hardly driven the car since i put them on. Quote Link to comment Share on other sites More sharing options...
Ashley P Posted June 26, 2023 Share Posted June 26, 2023 When I used to park my car for months at a time, I noticed the tires would "flat spot" after about 3 months. It would go away after several miles. After 6 months it vibrated for dozens of miles. Quote Link to comment Share on other sites More sharing options...
JohnC Posted June 26, 2023 Author Share Posted June 26, 2023 Replaced the wideband wire to gauge. The gauge did not work. Got a spare kit I had bought and installed a new gauge. BAM! Works now. I assume crushing the wire shorted out the old gauge. Everything seems OK for now. Still some weirdness on the test drive. Coming to a stop at a red-light, the rpm sounded different. I look at my wideband and it went to 0.8XXX Lambda and it started running and shifting crappy. Took off easy and it snapped back to normal and for the last half of my trip, it ran good. I think there is an intermittent issue going on. I'm going to replace both O2 sensors and see how it does. Quote Link to comment Share on other sites More sharing options...

JohnC Posted June 26, 2023 Author Share Posted June 26, 2023 Car is still doing wonky shit. Ever so many starts (don't recall exactly how many), I see Stabiltrack in the info thingy. Once that flashes, it drags like the battery is almost dead and doesn't want start. Really irritating. This is all the BS I see when I scan for codes via HP Tuners.

Ashley P Posted June 27, 2023 Share Posted June 27, 2023 That U0198 code....all U codes are communication faults. Sometimes it's difficult for a U code to set because there are comm issues....so, check to see if all modules are communicating. There COULD be a few off line. IF SO, that changes the ballgame.

JohnC Posted June 27, 2023 Author Share Posted June 27, 2023 Comm’s as in I need to drive it more? Drive it a while, a few starts later and it drags like the battery is weak, flashes Stabiltrak in the dash info and then acts like it doesn’t want to restart after being turned off.

JohnC Posted June 27, 2023 Author Share Posted June 27, 2023 With all those faults with lights, I bet I have a bad ground wire someplace? https://www.obd-codes.com/u0198 I did find one harness in the bumper off. I reconnected that, so that might be the front lights faults. The license plate lights, I had that known issue where the bulbs fall out of the cheap Chinese housing and end up between the bumper cover. I disconnected the bulbs so they wouldn’t melt in to the bumper or worse, the wire harness. I’ve not had license plate lights for years. Cam code has been there since the cam and DoD delete. I had cylinder imbalance since the broken rocker arms and beat up push rods. The leans codes, not sure. Id say those aren’t current their old. So I need to find the cause of this lost comm with tcm. Do you know where all the ground wires are in a 2010 Camaro SS for the tcm? Quote Link to comment Share on other sites More sharing options...
Ashley P Posted June 28, 2023 Share Posted June 28, 2023 Respectfully, I'm not answering any questions until you KNOW which modules communicate and which do NOT communicate. We have to know which ballgame we're coaching before making plays. Quote Link to comment Share on other sites More sharing options...

We have to know which ballgame we're coaching before making plays. How? It’s intermittent and I cleared the codes again. It might be that issue some of these Camaros have because the battery is in the trunk, grounds get weaker over time, gets heat soaked and then it drags like you have a nearly dead battery. When it drags like it has very little charge, it does exactly the same as it would with a weak near dead battery and sucks the voltage down enough that Stabiltrak flashes and that would indicate that the TCM probably intermittently lost power causing all this mess to happen. What do you think? Quote Link to comment Share on other sites More sharing options...

That's still what I think. GM Tech II and the SnapOn scanners I've used will "scan all modules" and list them. Check that against what the car is supposed to have. If one or more is missing, start there. Quote Link to comment Share on other sites More sharing options...

JohnC Posted June 30, 2023 Author Share Posted June 30, 2023 Camaro 5 group show it’s a very common issue. After heat soak, car doesn’t want to start. They add grounds. I seen mentioned: 1. Add starter ground 2. Add negative battery ground. 3. Add alternator ground 4. mention of 3ga wire 5. mention of oxygen free copper / marine grade copper wire. So far…..

JohnC Posted June 30, 2023 Author Share Posted June 30, 2023 Also… The problem has been isolated to the power post under the hood. There is a big loss at that connection The fix is to run a new seperate 0 gauge from the battery straight to the starter alongside the old cable Quote Link to comment Share on other sites More sharing options...
