Pretty happy with how it turned out data wise. Lots of 9.5s in there

Beautiful

Time to reveal this bad boy since y’all saw I was looking for a shell.


This is my 6.2 racing longblock that will be going into the hellcat. The car has 67k on it and this was designed to be a normal block that can handle some serious power. Built by MMX to my specs piston and rod wise and could handle well north of 22psi which is what I run now. The old Hellcat motor is a rare block, it is an early block with no BGE stamps. It is being sent to MMX for a refresh and will be turned into a 411 stroker for the shell. I haven't decided on forced induction path yet but I’m looking at entering the 8.5 index or heavyweight and I mean 7s/8s heavyweight.

Cant wait for you to get it going brother!! Badass!!

Nothing crazy just going over the fill procedure and inspecting the fluid drained. This occurred prior to going to the Rock.

It doesn’t say BGE on the back of the block? I have a real old hellcat block that says 6.2 on it, but in the bsck by rear main it’s still stamped BGE

This thread has become my personal wiki

Installed a 2-step, for drag racing purposes only 😆

@Speedy! here ya go

@Marc W finally installed!

Good deal! The “old” 6.2 block (15 & 16)) are stronger. They have a higher nickel content and are the desirable block for a big hp build. A new BGE is generic now.

Is there a reason you use this over the ZF fluid? Is it ok to use this in a stock transmission with stock frictions?

Well that’s a bummer my new block is a 2021…

for stock applications. I recommend stock fluid.

ts expensive which is why I was asking lol. When I swapped from the M6. I pulled the intercooler/trans cooler and drained it/cleaned it out with brake cleaner because I was told the ATF would be bad for the stock frictions, was just curious if I could switch to this as I need to change mine as well. Great videos man! Lots of good info here and high quality

I use the factory 8/9 speed fluid for my trans and have seen no reason to change to something else in my particular case. It’s worked really well for me over the years.

. Nothing wrong with the 6.2 BGE. I’m guessing that when they first came out with the Hellcat, they overkilled the block a bit. Concern of the unknown. Afterwards they started using the standard BGE specs. A “source” told us that the early 6.2’s were a stronger metallurgical deal that they later determined wasn’t necessary for the stock Hellcat. For somebody pushing a1500+ hp build…that is good to know. For most it won’t matter.

Sad part is they were much cheaper then to 🥲

Im running a racing trans and this is what Pure tells me to run. The fluid is just as expensive.

No doubt, however my builder tells me to run this.

Im no where near there lol!

I got one Ill sell you at today’s prices. J/k im keeping that bish…

Those prong edges are pretty cool, definitely makes life easier, where did you find them? I’d like to get my hands on one.

 

[Speedy!]

Good info on the 2 step. I'd velcro the controller.

I've heard 2 step will murder cats....I need to research bur could def use one to help my rt.

It does the same thing launch control does, only it doesn’t activate the dumb traction control after you launch

Launch control will cut ignition and fuel while also limiting boost as well. This two step setup will just cut ignition. I had fun playing with it on my car when I still had it hooked up from early th400 testing. That is, I tried incorporating use of the two step for launch and better reaction time when I had the 8 speed back in. I liked it and wish I got to play with it some more while I still had the 8 speed installed. My reaction times improved .100 - .150 right off the bat and could probably get even better with practice.

The 2-Step is only good for one thing with our Hellcats. When combined with a quick release transbrake (like in a T400) you will have a quicker reaction time on a pro tree. Releasing a single depressed button takes less time than the footbrake/gas pedal footwork you have to do otherwise.

Here’s another.

Even on an A8 it can help when setup well. Being on the two step with the foot brake, it still takes away the time delay that occurs from having to press the gas pedal and then the time delay of the factory pcm reacting to that gas pedal press. With the two step, everything is essentially WOT ready to go once you release and come off the foot brake. I saw improvement with limited testing. Combining it with a real trans brake would improve it even more.
