Boosting a 6.4 Scatpack engine... is it safe? 

So in other words, it’s safe to boost a 392 as long as the tuner knows what he’s doing

Great vid. Exactly what I was looking for. I want more power out of my 392, but not trying to turn it into a hellcat or rebuild the entire engine. Thanks for the info.

Very informative, thanks for sharing

I know this video is three years old and I always see folks asking if something is still running etc. And while I can't speak to this vehicle, I can absolutely speak to my own. I have a 2011 SRT8 that I installed my own Magnuson 2.3L TVS on. I installed my blower at 42k miles and the tuning was done by a well respected tuner of Hemi's. My car just rolled over 80k miles this weekend and it's as strong today as it was the day I installed the blower. I am running 6lbs on my setup. Like you said in the original video the tuning is the key and also not trying to go too crazy with the boost. The rings are gapped tight and if you build too much heat in the cylinders then those rings will bottom out and then the top of the piston will pop off. 6-7 lbs on a stock 6.4 with solid tuning is safe. Anything more than that and you should, imho be opening up the block to replace those slugs and lowering the compression.

I always wonder how many people commenting on what’s correct on this subject actually have boosted 392’s ?

when boosting any NA motor it's always good (sometimes necessary) to gap the piston rings, otherwise you need to run mild timing and low AFR to decrease combustion temps as much as possible (which limits your gains).

They say you gotta be spot on with a tune for a scatpack that's building boost

I was thinking about this would it better to drop In forged pistons n rods

I wonder if this thing is still running strong?

How much do y’all charge for installing and tuning the setup?

what's the 0-60 with the procharger???

Can you send me the type of blower you put on. I have the same véhicul but 2022 and i want to had more hp.

I doing a 6.4 conversion on my Jeep Gladiator. is there a kit or a way to put a Procharger on it ?

I'm @ 22lb boost with my Challenger Scat but I didn't cut any corners fully forged bottom MMX components fellas

But how much is this to do

Do you offer remote tuning for a stock scat pack with a complete procharger kit?

What are your thoughts I have a 2.9 Whipple and I am at 638 RWHP around 12 lbs of boost. My tuner person has it tuned down. I am wanting to get more out of my motor because I was able to get around 670 RWHP. Oh I am on E85 fuel also. You think my 6.1 can handle it like a 6.4 can handle it safely

How much HP/TQ will the stock scat pack 8 speed trans handle without supporting mods?

How much for this exact setup Ill drive up Im in Chicago lol

I'm running a stage 2 whipple and I'm getting 9psi on my 18 392 all stock internals. But I have to change them, if I want to put a bigger throttle body on it. I'm at 611hp and torque 599.

Personally I would not supercharge without forged internals on this motor. Interesting on the neural network--if the base ECM is being used to modulate parameters, and if it is indeed a neural network used to regulate AFR , timing, etc, then really should the tuner not just be setting target parameters and call it a day? If we see customers with lean conditions at max rpm, that to me sounds like corner cutting then or trying to optimize AFR and sub-redline rpms. Definitely would like to see richer conditions at the top end.

This guy seems to know these hemis well but I don't think I'd trust boost on my 392 without rods and pistons at the very least. What would the extra cost be to add forged rods and pistons? Another 4-5 grand including the install?

How much would a 6.4 make with forged pistons and a turbo make

SO many ppl in thiis comment section and every comment section always saying the 6.4 is rhe 6.2 stroked and they are totally wrong lol. Google is free. There are videos of Dodge explaining this.

The problem isn't just the pistons. It's stroked 6.2. basically it's fully stroked to 6.4 and the more the crank sticks out the block. The weaker the bottom end becomes. There's a reason why dodge does not use the 6.4 and uses the 6.2. yes you can boost a 6.4 . But down the road don't be surprised if your bottom end blows out or you crack a piston. Seems funny nobody in these 392 actually asks why does dodge use the 6.2 and not the 6.4 lol.

Is it safe to go up to 7LBS

Nope need expensive upgrades

STD !!!! Inflated HP numbers… sad

What about 2014 hemis and below
