2022 Challenger Hellcat Redeye engine rebuild after water damage

[atom327i]

Hi Everyone!

I am Tamas from Budapest, Hungary.
I would like to share with you my current Redeye Hellcat build.

The background: I got last week my Redeye delivered. It's motor has sucked a lot of water.
I have already taken it apart.
The supercharger survived, and the heads, cam, lifters, are good too. Crank is at the shop for crack investigation.
Unfortunately at the insurance field the car has waited more than 6 monts with water in the combustion cylinders.
I have now issue with the engine block, because the water has corroded the cylinder walls.
The machine shop will try to hone, but I am not sure, how the result will be measuring (whether would stay in tolerance)
Has anybody faced with such an issue?

I would appreciate any help, suggestion or suport on parts, or methods.
In Europe there are no salvage components for this engine at all, and also all parts need to be ordere from USA (extra VAT and custom charges, long delivery) So the build shall be planned carefully to be ok on budget as well.
Greetings to the US

Welcome!

Collectively we've all done a lot of rebuilds, but I'm not sure I've ever seen anyone do a water damage rebuild. That doesn't mean that you can't get some help, there are some very talented people here on the forums.

Good luck, I'm sure somebody will chime in and help.

Maybe get it sleeved? Or a new block...

How did the engine sustain water damage

I do not really trust ssleeving on this type of engine. In the Hemi engines the piston goes really low, out of the cylinder. So there will be no support at the bottom for the sleeve. Redeye/Demon block has no orderable part number as new. Or do you have one?

Thank you! I am on the way to set up different plans. I have built a lot of BMW engines, stroker race engine as well, several 5.7 HEMI engines. But for 5.7 still I can find block used in Europe. But for regular Hellcat it is impossible, and now I need redeye/demon block, so no dreams I have .

Do you know MMX Modern Muscle Xtreme?
They are offering snap in pistons with 0.01inch oversize. It sounds a good alternative to overcome on this surface corrosion:

How did the engine sustain water damage

The story of it is unclear. But the car has no sign of flood damage, no water intrusion into the passenger area or in trunk, even no signs in case of structural body parts. So my assumption is, the driver passed through a flooded street with higher water level and the splitter has helped the water into the hood openings and into other air inlet parts with running engine. I have seen multiple videos like that. The vehicle is from Florida from time of hurricane saison... So this is an assumption. The water was clear water, no mud, or salt.

Welcome to the forum.
WOW, Nice to see your shop and work you're doing. Amazing to see hellcats in other countries. Sounds like you are on top of the issues, and I wish you the best on your journey! We in the USA often don't think about how hard it is for others to simply get what we can walk into any dealer or shop and find parts in a day or two.
