2.72 Hellraiser.

So + 10 lower and 2.72 up top?
Take blower belt off and spin pulley by hand and look in TB to see if rotor are turning too or not. If they are out your hand in there and see if they still spin if you try and hold them back. You may have had coupling fail between snout and blower. PCM will throw a TB error if it doesn’t see expected boost at certain rpm.

I’m thinking something was missed in engine diagnostics

There is a whole slew of them. I sent you a compare file.

Well? What did you find?

Well one thing is for sure a 2.72 and lower is a nasty combo! Agreed @16GoManGoHC2?

Yes, takes special prep of blower coupling security to survive the combo, but it does produce results! M6 remember

Best part is all 3 have a pause in GPS speed half way through the pull from tire spin

thats the 3-4 manual shift there auto guy lol, but yes tire spin can be seen in the orange G force squiggly up and down graph from spinning to well past 100, and sometimes on the 3-4 shift she’ll break loose in 4th on the shift, it’s a fun ride, most I’ve taken on a 60-130 highway pull say no more, once was enough lol. A street 1/4 pull is even more brutal, I need to put a go-pro on the passenger side visor pointed at the seat for when I stomp on it at 50-55 the facial expressions are priceless as they get pushed harder and harder into the seat as third pulls hard for its entire duration lol

Duh I forget about the "SLOW" shifts from manual cars. If you just had something I could tune the trans on that wouldnt be an issue

Necessity is the mother of all invention. After doing plugs it was time to do the dreadfull BMR tank fill. Since its almost impossible to put it under vacuum using anything I had a friend plasma cut me a lid. After that I picked up a roll of cork rubber and made a gasket. I got it to 15 psi of vacuum using my little harbor freight. It was a sigh of relief to hear the bubbles hit the tank. Filled

Kong full CNC port, I mean everything. Kong full supercharger race rebuild. Things are about to get fucking nutty. Metco 2.75 so the tune wont have to change.



Sending my current 2.4 to valhalla tomorrow night at MIR. Stay tuned for some live action.

So have you ran it yet with tighter gapped plugs to see if miss fires reduced and the occasional knock there not there thing abated??

no knock so far with the tighter gap. Also spoke with a dodge tech, there is an acceptable amount of misfires within a period of rpms, he says if the pcm isnt firing a code im being over paranoid.

@16GoManGoHC2 that assumes there is a code😂

Good to hear knock abated, I may try closing gap as well as I get the here and there for no reason STKR as well, what did you go to .026” right? As far as being over paranoid I would say there’s never such a thing lol especially if you have a reason to be hunting for something like this occasional knock thing. What rpm band would you see the STKR in the most? Me 1,2,3 clean and get it in the top of 4th (stick remember) at times even with just 100F manifold temps. Happened last night, one run totally clean next run had 1.5 degrees around 6200 rpm, ran again and clean. And this was all back and forth across the bridge like a nut in a 10 minute period so it got hotter and hotter as she was beat on but the coolest and hottest run where clean but the middle one dialed timing back. Definitely going to try closing up the gap some as well. Keep us posted on this topic please.
