AMG G63 4x4² „Nuthin but a G thang“.

The AMG G63 4x4² brings driving performance to the segment of unadulterated off-road vehicles in unexpected form.

The AMG 4.0-litre V8 biturbo engine generates 430KW (585HP) in this model, and delivers a maximum torque of 850Nm. This is available across a wide rev range between 2.500 and 3.500 rpm, and provides a sense of effortless superiority. It absolves a sprint from zero to 100 km/h in 5 seconds.

The two turbochargers are not positioned on the outside of the cylinder banks, but inside the cylinder „V“. Advantages: a compact engine design, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts. The eight-cylinder delivers its power with muscular torque in all engine speed ranges, combined with maximum efficiency for low fuel consumption and emission figures.

Two twin scroll turbochargers are used for optimal response.

The housing is divided into two parallel flow channels. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct, that from the second and third cylinders to the other duct.

The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output, more torque at low revs and very fast response times.

I want to try red light therapy so badly!! Please share with us your experience when u try it and if u have any recs, I'd appreciate it a lot ❤️

I will give you an update in like 12 weeks time ( I have put it in my calender)

What I want to make crystal clear is that red light therapy should not be expensive. Its coloured light, albeit at a specific wavelength but coloured light nonetheless. When you look to buy red light products or any light therapy, you have to make sure you get the correct one wavelength. For red light, its 630nm to 700/850nm. The papers I have read seem to hinder between 700-850 so the one I got is closer to 630.

Like I said, there is no reason to be forking out hundreds to thousands of pounds for this. Literal chicken light works as well.

Advantages of 400G QSFP-DD Optical Transceiver Module

Backward compatibility: Allowing the QSFP-DD to support existing QSFP modules (QSFP+, QSFP28, QSFP56, etc.). It provides flexibility for end-users and system designers.

 Adopting the 2x1 stacked integrated cage/connector to support the one-high cage connector and two-high stack cage connector system.

SMT connector and 1xN cage design: Enable thermal support of at least 12W per module. The higher thermal reduces the requirement for heat dissipation capabilities of transceivers, thus reducing some unnecessary costs.

ASIC design: Supporting multiple interface rates and fully backward compatible with QSFP+ and QSFP28 modules, thus reducing port and equipment deployment costs.

Applications

400G QSFP-DD optical transceiver module is used in 400G Ethernet, data centers, telecommunications networks, cloud networks, Infiniband interconnects, high-performance computing networks, 5G, 4K video, IoT, etc.

so Lucy remembered that as a teenager we really wanted to try near infrared photography, and we finally got some filters and stuff for it.

we're going to get a full spectrum converted camera eventually but in the meantime these were taken with an 850nm filter over our phone camera

and then this one where we played around more with the post-processing on it

we also have a few taken with a 590nm filter but we're figuring out what to do with those

AMG G63 „Nuthin but a G thang“.

The AMG G63 brings driving performance to the segment of unadulterated off-road vehicles in unexpected form.

The AMG 4.0-litre V8 biturbo engine now also replaces the previous 5.5-litre V8 biturbo engine in the G63. It generates 430KW (585HP) in this model, and delivers a maximum torque of 850Nm.

This is available across a wide rev range between 2.500 and 3.500 rpm, and provides a sense of effortless superiority. It absolves a sprint from zero to 100 km/h in 4.5 seconds. This dynamic performance is maintained up to the limited maximum speed of 220km/h, or 240km/h with the AMG Driver‘s package.

The two turbochargers are not positioned on the outside of the cylinder banks, but inside the cylinder „V“. Advantages: a compact engine design, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts.

The eight-cylinder delivers its power with muscular torque in all engine speed ranges, combined with maximum efficiency for low fuel consumption and emission figures.

Two twin scroll turbochargers are used for optimal response.

The housing is divided into two parallel flow channels. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct, that from the second and third cylinders to the other duct.

The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output, more torque at low revs and very fast response times.
