Hi. I’m new here. I just purchased a 2022 Jailbreak Charger. 807HP.
1) Does anyone know where the EXTRA 10HP over the standard redeye 797HP comes from? Magic?
2) I’d like to add the Direct Connection Prestage kit, 5 degrees more timing and the 180 F thermostat, but that takes the 797HP Redeye to 802 HP —— so do I lose 5HP???
3) Mostly I just want the 180 F thermost just to keep the engine a bit cooler.
4) Thoughts on the other kits on hellcat and redeye too?
4) Any advice on an oil breather catch can would be welcome too.

Thanks in advance for ANY advice. I hope I did this correctly!
Regards, Q

The 10 extra HP is from a redline increase by 100 rpm, as I understand it. The kits are all for Demons, Redeyes, and lesser trims. They may include jailbreak and give the extra 5 on top of the 807, but that hasn't been established yet.

1) 1134 CFM (Demon) vs 1130 CFM (Redeye); hood airflow difference (larger hood scoop on the demon and there is a plastic baffle difference above the air box (Redeye slightly more restricted vs demon). 6400rpm (Demon) vs 6300rpm (Redeye). Both are the same engine SAE certified at 812hp @ 6400rpm.

2) The increase on the direct connection is spark advance and likely 100rpm increase to redline. It suggests the 5hp difference is due to the hoods airflow. But really, both engines make 812hp.

3) $59 aftermarket Mishimoto 180 tstat.

4) Billet tech has been around for awhile and made a decent catch can.

JB and SS have the same hood as the RE and are rated 10hp more. Airflow has nothing to do with it. It’s just the 100 higher rpm measurement.

Ah, it was for a 2022 Charger.
Yup, just the rpm difference.
797 bhp (595 kW) @ 6,300 rpm (advertised)
807 bhp (601 Kw) @ 6,400 rpm (advertised)
812 bhp @ 6400 rpm (SAE certified, Demon, Redeye, Super Stock, JB)

@Q-36 Mishimoto is the Best 180 T stat. I have this installed on My Hellcat now.
Description
Your high-performance 5.7L, 6.1L, 6.4L or 6.2L HEMI needs a reliable and effective cooling system to extend engine life and perform at its absolute best. Mishimoto is proud to introduce a racing thermostat specifically designed for the 5.7L/6.1L Hemi engine. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat will open at a lower temperature (180°) compared to standard thermostats (203°). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Whether your vehicle is stock, cammed, or blown, the Mishimoto racing thermostat will provide superior cooling efficiency to keep your vehicle on the road and out of the shop. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty
*Does not Work on 6.4L Rams


For all Mishimoto Lifetime Warranty claims, please visit:
Lifetime Warranty


My husband back in 2015 Popped a Metco Breather on our Hellcats, and they are still there today.
Metco is also a supporting vendor on here.https://www.hellcat.org/forums/metco-motorsports.23/




Description
This breather installs as a direct replacement for the OEM oil fill cap, and absolutely no modifications are required. The precision-machined helix in the bottom of the billet stand fits tightly into the fill tube, and the seal is maintained by the included o-ring.

In supercharged applications, combustion pressures invariably find their way into the crank case, and this pressure contributes to pumping losses, elevated oil temps, and premature failure of engine seals. The breather serves as a high-flow vent to allow any pressure that builds to easily vent into the atmosphere.

This breather is fitted with our proprietary APV one-way check valve, so while internal pressures can pass through, outside air cannot be drawn through the breather and into the inlet tract of the engine. Your engine tune will not be affected by the installation of this breather.

Like all Metco breathers, this unit is CNC-machined from 6061 aluminum, and micro-finished on the exterior surface. The filter is a high-quality reusable unit manufactured in the USA by S & B filters.

Total installed height is less than 3". This breather may not be legal in all states.

For earlier Gen III Hemi applications using a screw-in style oil cap, please see the MBR0012 breather listed elsewhere in this section.

CANNOT BE SHIPPED TO CALIFORNIA**

180 degree thermostat does not make an engine run cooler. It means the thermostat opens at 180 to allow radiator fluid to start flowing through the block.

if the engine’s natural temp is 225, it will still run at 225 even with a 160 degree thermostat. If the engine runs most efficiently at 225, a 180 will hurt more than it helps - especially in cold weather when you want the block to heat up.

Same is true if the engine runs naturally at 180 and most efficiently at 225 but the user puts a 180 degree thermostat in, that hurts performance more than helps.

to add; i had a 63 Dodge Dart, 4-door, with a 225 Slant 6, and living in San Diego. I took the thermostat out all together be cause I didn’t want a $5 piece failing in the closed position thereby overheating my engine. Most older, carbureted engines i do that to for that reason alone.

Long explanation

Yes.

The thermostat controls the minimum operating temperature of the engine by beginning to open at the set point and then throttles coolant flow to maintain a minimum operating temperature if needed.
Once the minimum operating temperature is reached the upper operating temperature limit is controlled by the radiator’s thermal equilibrium with the environment. That is a function of heat rejection to the cooling system and heat dissipation from the radiator.
Radiators (heat exchangers) are sized with excess capacity and the thermostat controls the limiting lower temperature. The reason for excess capacity of course is ambient operating conditions; hot day, heavy load/throttle, low vehicle speed operation (partially compensated for by the fan set point) otherwise overheating, also known as, thermal runaway occurs.
If the lower portion of the cylinder remains above the dew point of the combustion products there will be no condensation formed within the cylinders from the combustion products and if the oil temperature is above 180F condensation products will evaporate from the oil (general rule of thumb is the average oil temperature is 50 degrees F below the maximum oil temperature at hot spots, so water is easily boiled off as well as acid products).
Aluminum expands at 10x10*-6 in/in and iron at 6x10*-6 inches per inch. If you know the cylinder bore clearance you can solve for the thermal expansion crossover point. In other words, aluminum expands faster than iron so there is a crossover point where the engine will seize; piston to wall clearance becomes zero. We never want to get there.
Polymers and oil degradation rates doubles for every 10 degree C operating temperature rise (or 18 degrees F). Basically, too hot is bad, too cold is bad.

My goal is to reduce the lower set point from 203F which is controlled by the thermostat to 180F. Since there is margin built into the cooling system this will allow the engine to run at a minimum of 180F on very cold days and below 203F given the cooling margin. This should lower the engine operating temperature by approximately 20 degrees since the radiator has margin for extreme ambient temperature operation. Engineering design is for the engine oil temperature is to live at 20-30 degrees F above coolant temperature.
Operating at 180F or below 203F will extend oil life, seal life, in addition there is more resistance to knock/ping because of lower charge temperature.
We know that these engines go into limp home mode at coolant temperatures of 250F for a variety of reasons, knock, thermal expansion, oil degradation, seal damage.
Additionally, there is more thermal capacity in the engine IF it starts a performance run at 180F, a 70-degree margin to 250 F versus a 47-degree F margin from 203F.
My desire for the “stage kit” was to be able to use a 180F thermostat with a new factory calibration. The 5-degree spark advance is a nice performance addition.
If that calibration kit is not available, I’ll probably just put in a 195F and split the difference.

Hopefully that clarifies my goal. Appropriately, lower engine operating temperatures for enhanced durability while avoiding operating the engine outside its intended design parameters.

@ Q-36: FROM WHAT I UNDERSTAND: Standard Hellcats, Redeyes and Super Stocks are ALL tuned to 812 H.P. @ the crank. Also, All Direct Connection packages are DEAD as per President Joseph Robinett Biden. Again, this is FROM WHAT I UNDERSTAND. Please, no attacks from the peanut gallery.

I know 3 people that had those fell apart on them but ok : )

@Q-36 milodon 16406. Better quality, half the price


Mine runs right at 185°

The reason the factory doesn’t ship it like that is the same reason the ring land is so high on my pistons - emissions - no pump gas blower motor will make more power above 200°. It will make less power but it will be more eco friendly

Patiently waiting with crossed fingers these come to fruition as want a pre-stage kit for our new to us 600 mile 2015 cat and hoping that tuner is not married to a vin like our old mustang ford tuner was years ago as would be nice to double dip and use on the wife’s 20k mile 2016 cat. Would add the stage 1 to both as well. Right now those part numbers are not found on the dcperformance website.

Yup. That’s a perfect example, That little bit of unreacted (quenched) hydrocarbon - move the ring land up, raise the ring temperature, probably increase the possibility of ring flutter, increase coking in the land, reduce knock margin all for the last smidgen of HC reduction, right up there with the fast idle start to light off the cat….. oil pressure can’t come up that fast. I cringe when I start it. Complimentary oil temp reduction will improve piston crown cooling and reduce coking too.

Thanks for the 185 F data point. I appreciate the real experience input.
