The '''VRH''' engine family consists of several racing engines built by [[Nissan|Nissan Motor Company]] beginning in the late 1980s. All VRH engines are in a [[V8 engine|V8]] configuration and can be either [[naturally aspirated engine|naturally aspirated]] or [[forced induction]] in design. Some of the VRH engines are loosely based on Nissan's production V8 blocks including the [[Nissan VH engine|VH]] and [[Nissan VK engine|VK]] engines, while others were designed from the ground up for racing and share no components with production blocks.

The Nissan '''VRH''' engine family consists of several racing engines built by [[Nissan|Nissan Motor Company]] beginning in the late 1980s. All VRH engines are in a [[V8 engine|V8]] configuration, with either [[Naturally aspirated engine|natural aspiration]] or [[forced induction]]. Some VRH engines are loosely based on Nissan's production V8 [[engine block]]s, including the [[Nissan VH engine|VH]] and [[Nissan VK engine|VK]] engines, while others were designed from the ground up for racing and share no components with production blocks.


The name "VRH" comes from the engines' [[V engine|V configuration]] ("V"), their purpose as racing engines ("R"), and the fact that all of them have [[V8 engine|eight cylinders]] (with "H" being the eighth letter of the [[Latin alphabet]]).{{Citation needed|date=April 2021}}

In 1987 Nissan began work on an engine exclusively for race use and began work on the VEJ30 engine, developed by [[Yoshikazu Ishikawa]]. This engine was based on old technology, and was not a success. For 1988 the VEJ30 was improved by Yoshimasa Hayashi and renamed the VRH30. Changes included increasing [[engine displacement|displacement]] to 3.4L.

This engine was still based on the obsolete VEJ30 and development of the all new VRH35<ref name="Subete">Super Car Chronicle Part 3 レーシングカーのテクノロジー ISBN 4-7796-0785-X</ref> was started in parallel with VRH30. In 1989 the VRH35 appeared as a new development engine and was used in the [[Nissan R89C]]. The improved VRH35Z appeared in 1990 in the [[Nissan R90C|R90C]].

A 3.0-litre variant of the VRH35Z was also used in the 1998 [[Courage Compétition|Courage]]-Nissan C51 at the [[1998 24 Hours of Le Mans]]. Both C51s [[Did Not Finish|failed to finish]].<ref name="racingsportscars">[http://www.racingsportscars.com/type/archive/Courage/C51.html Courage Nissan C51]</ref>
In 1997 Nissan, working in partnership with [[Tom Walkinshaw Racing]], fielded an updated version of the engine called the VRH35L in the [[Nissan R390 GT1|R390 GT1]]. This revised engine produces around 641 hp (478 kW) at 6800 rpm.


The design of the engine was later sold to [[McLaren Automotive|McLaren]], where it served as the basis of their [[McLaren M838T engine|M838T]] and [[McLaren M840T engine|M840T]] engines (which were used in all of McLaren's line-up since the [[McLaren 12C|McLaren MP4-12C]]).<ref name="caranddriver">{{cite web|date=2011-02-01|title=Car & Driver: 2012 McLaren MP4-12C Tech Trickledown|url=http://www.caranddriver.com/reviews/car/11q1/2012_mclaren_mp4-12c-first_drive_review/tech_trickledown_page_2|access-date=2011-03-27}}</ref><ref>{{Cite web|url=http://www.caranddriver.com/reviews/2012-mclaren-mp4-12c-first-drive-review-tech-trickledown-page-2|title=2012 McLaren MP4-12C First Drive|date=14 February 2011}}</ref>

The Nissan VRH engine family consists of several racing engines built by Nissan Motor Company beginning in the late 1980s. All VRH engines are in a V8 configuration, with either natural aspiration or forced induction. Some VRH engines are loosely based on Nissan's production V8 engine blocks, including the VH and VK engines, while others were designed from the ground up for racing and share no components with production blocks.

The name "VRH" comes from the engines' V configuration ("V"), their purpose as racing engines ("R"), and the fact that all of them have eight cylinders (with "H" being the eighth letter of the Latin alphabet).[citation needed]

History

[edit]

In 1987, Nissan began work on an engine exclusively for race use; the result was the VEJ30 engine, developed by Yoshikazu Ishikawa. This engine was based on old technology, and was not a success. For 1988, the VEJ30 was improved by Yoshimasa Hayashi and renamed the VRH30. Changes included increasing the displacement to 3.4 L (3,396 cc).

This engine was, however, still based on the obsolete VEJ30, and development of the all-new VRH35[1] was started in parallel with the VRH30. In 1989, the VRH35 appeared as a new development engine and was used in the Nissan R89C.

A 3.0-litre variant of the VRH35Z was also used in the 1998 Courage-Nissan C51 at the 1998 24 Hours of Le Mans. Both C51s failed to finish.[2]

The design of the engine was later sold to McLaren, where it served as the basis of their M838T and M840T engines (which were used in all of McLaren's line-up since the McLaren MP4-12C).[3][4]
