2 dead cylinders and only 14% off? So what caused the 2 dead cylinders...
He still has "some" compression as he states... around 30 psi.
So its still burning, however obviously not a full fire condition.

I was just stating that the deviation of the banks was an after effect, of the main issue at hand. AS to the cause that started the two dead holes, thats not my place to speculate about.

It was lean on that bank, because the dead holes throw the AFR's off.
(Can't read unburnt fuel AKA misfire)
If that's the case I would have thought it would read rich not lean? Because the plug is still firing it wouldn't be a misfire, no? I don't know just trying to understand?

Really sucks for the OP though!

Quick question for the OP, was the car running fine and the first couple of hits/logs went ok then it started to act like this? Or was it reading lean right from the first hit?

Opposite,..... misfire or incomplete burn = false lean reading.

You can literally dump a bucket of gas into a piston, but if it doesn't fire it (or completely burn) its not going to register. However it will see the "air" go by the sensor, and thus = lean reading. :)

Nothing wrong with asking a question... thats how we all learn. :)
And the whole point of forums. :)

lots of boost on pump fuel

I've gotten 93 at stations that read like 87, I've gotten 91 at stations that read like 93

by read, the timing the car is adding or pull

14-15 is enough to make 850+ with the right fuel and timing, now, you pull back timing to help

the 15's are stronger, but not light years above the 11-14, again, the biggest culprit being the rings, the top of the piston is still very thin.

but, good fuel like e85 takes you far, look at process (jay) look at our car.

we took the block out before taking out the piston

wanted to add something in here, now that i know where the tuning was at. this shouldn't deter anyone from wanting to do a blower on their car.

this could or couldn't be a boost related issue. with the logging with lund, Shane has been had some misfire codes from the beginning

sometimes i get screen names mixed with customer names. shane had some issues with getting the timing right on the car and the car was running really bad when he called me last month. he took it back apart and believed he had everything put back together correctly, but with his initial logs with lund, lund has had to change fueling more than normal on these cars

just want to make sure all the info is in here since I'm getting calls with people scared to install their kit.

issue could be a combo of multiple things. Timing incorrect. Too much boost with not good fuel. Bad fuel. Etc

I did have some misfire codes from the beginning one of my brisk spark plug was bad and gave me some misfire codes along with an injector coming unhooked. My misfortune shouldn't scare anyone away from installing this kit. I'll have time to fix it while I'm waiting on Paxton to fix the charger.

Yikes, 14% is alot. So if you were 11.5 or so that puts it up over 13:1 on the one bank...







E85 is forgiving, but I dont think even E85 would save from a 15% swing on AFR...:thumbsup:

Actually it will. Not saying you should but e85 is extremely forgiving. Way way way more than pump gas. I've seen it save an engine at trims over 25% out.

Sorry to hear that man.

I know how you feel.I broke a piston with my Hellion TT when I had a boost spike.My car had just 4000 miles.I had plan to build it eventually but no quite yet.
lol.
Well I guess it simply happened sooner rather than later.

My engine was just put back together with a 11-14 alluminator short block.

You can buy a complete 2015 alluminator now but i doubt the short block is going to be any different from the 11-14.Obviously the heads are different

I should be picking it up tomorrow



My engine is back together with the 11-14 short block
Also did the MMR billet crank sprocket
Runs good but obviously still babying it.
Looks like I am going to do E85 after all.I don't know if t would have saved my stock engine but want to be as safe possible with the alluminator motor ..... before I turn it up.
I may have to drive up to see beefcake and have his shop install the fore system.

On3 car should be ready in a few weeks.:headbang:

I am going to build the block that came out of the Hellion car and eventually put in the on3 car.I would love to sleeve it to but that is another $2.5 K.
Also worried about tuning options for the 5.2.
Already have limited options to tune the 5.0.

I guess it is time to start my own build thread.
I am going to call it " A tale of twins with twins"
lol

Did you install the OPG and Timing gear yourself?

Most likely not related to Paxton. OP......did you have these issues after you installed the opg and timing gear?
