原标题：3-Rotor Turbo & NOS, 4-Rotor NA: Drag RX-7s Done 2 Ways
At last month’s Option x G-Works Super Drag Festival, two FC3S Mazda RX-7s caught my eye in the Central Circuit pits. While the pair share some similarities – including the fact that they were both down from Hokkaido – they’re quite different machines under their ultra-clean, white bodywork.
在上个月的Option x G-Works超级速度节上，两辆FC3S马自达rx -7在中央赛道的维修站引起了我的注意。虽然这两款车有一些相似之处——比如它们都来自北海道——但在它们一尘不染的白色车身下，它们是两台完全不同的机器。
At a quick glance from a front-end view, the first car looked a lot like any other tuner-style FC3S we’d feature on Speedhunters. But as I got closer to the SWATT/Zeroyon Factory RX-7, the details you only find in a purpose-built drag car began to present themselves.
单单看这辆车的正脸，你并看不出这辆车与我们在Speedhunters中展示的其他调谐风格的FC3S有任何不同之处。但当靠近swart /Zeroyon Factory RX-7时，你就会察觉出那些只能在专业打造的直线加速赛车中找到的细节。
Weld Racing wheels and Hoosier tyres – 29×11-inch slicks out back – check. Flat rear wing and parachute, check. Polycarbonate windows all around, check. 5-inch tachometer with shift light, check.
Weld Racing和印第安纳轮胎-——向后滑出29×11英尺，到位！平后翼和降落伞，到位！随处可见的聚碳酸酯窗户，到位！。带换档灯的5英寸转速表，到位！
Compared to most of the other cars competing at the Super Drag Festival, the Mazda looked quite stock, but seeing the huge side-exit exhaust sprouting from the right front fender, I knew there was going to be something definitely not stock under the hood.
与参加超级速度节的大多数其他赛车相比，这台马自达看起来相当“正常”，但看到巨大的侧出口排气从右侧前挡泥板冒出，我就知道引擎盖下的什么东西绝对不能用“正常”形容。
The RX-7’s owner and driver, Akira Kato, was keen to show me what his FC RX-7 was packing, and it’s some serious rotary firepower. We’ll start with the Garrett GT4508R turbocharger (featuring an 80mm compressor inlet), with fist size for comparison. Given the size of the turbo, I was surprised to learn that it’s not even the biggest Garrett available; up to 106mm versions are available right off the shelf.
RX-7的主人兼司机Akira Kato，热情地向我展示了他的FC RX-7的构造，后者得益于转子发动机的功劳非常强劲。您先看看Garrett GT4508R涡轮增压器(具有80mm压缩机入口)与拳头大小的比较。考虑到涡轮的大小，我很惊讶地发现它甚至不是最大的Garrett涡轮;据悉，宽达106mm的版本即将上架。
The engine itself is a 3-rotor 20B from a JC Eunos Cosmo, but Kato-san
has thrown a lot at it, including a whole of boost and a shot of nitrous
oxide to get things moving. According to the team, the engine has a
9,200rpm redline and makes 950ps, which is more than four-and-a-half
times what the RX-7 left the Mazda factory with. Yikes.
发动机本身是JC Eunos Cosmo强化过的3转子，但加藤先生投入了更多，包括完整的推进装置和一氧化二氮动力系统来使这台马自达“移动”。根据该团队的说法，这款发动机的红线为9200转，转速为950ps，是RX-7离开马自达工厂时的4.5倍多。哇！
As a mostly stock chassis car running a Jerico transmission and R33 Nissan Skyline GT-R rear end, the RX-7 is no lightweight, but Kato-san has made good progress with the car and is banging on the 8-second door having run a best pass of 9.052 at 233km/h earlier in the year. That time is quick enough to claim the fastest rotary spot in the Japan Drag Championship’s ‘RWD Over 2.5L & 3-Rotor Engine’ class (fourth outright).
介于这款RX7采用了Jarico变速箱和R33日产Skyline GT-R后端底盘，它的重量并不轻，但加藤先生在这款车上取得了不错的进展，今年早些时候以233公里/小时的速度跑出了9.052的最佳成绩，直接冲击着8秒大关。这个速度足够快，以至于可以在日本直线加速锦标赛的“RWD超过2.5L和3转子发动机”级别中拔得头筹(总体第四名)。
I can’t find any videos of the SWATT car running on the day at Central Circuit, but you can check out this video from a Motegi event earlier in the year to see and hear it in action.
我找不到任何swat赛车当天在中央赛道运行的视频，但你可以在茂木今年早些时候的一次活动中看看这辆车的身姿，听听三转子高亢的声浪。
The other white RX-7 storming down Central Circuit’s straight a few weeks back is one of Japan’s most famous domestic drag cars owned by a true zeroyon OG. It’s been in Makato Watanabe’s hands since it was brand spanking new in 1986 and drag raced from day one, so I can’t decide which is the biggest legend – Watanabe-san or the Mazda. By now they would have surely formed some kind of symbiotic relationship, so they both deserve equally high praise.
另一台在几周前极速冲入中央赛道的RX7 FC3S则是日本最著名的国产直线加速赛车之一。它的所有者是如假包换的zeroyon OG。自1986年它出厂以来，就一直在渡边的手下为直线加速赛而改装进化，所以我无法判断谁才是真正的传奇-渡边还是马自达。到现在为止，他们肯定已经形成了某种共生关系，所以他们都应该得到同样的高度赞扬。
For the first 10 years of their relationship, the RX-7 dominated the Hokkaido street drag scene with an aggressive side-port 13B turbo setup. In the early 2000s, the car was converted to a full tube frame chassis, which Watanabe-san purchased by mail order from RJ Race Cars in the USA. The parts arrived, and, relieved that nothing was missing, Watanabe-san built a chassis table in his workshop and welded the frame together. Some modifications were required, but the RX-7 body panels fit.
在这段关系的前10年，RX-7用强悍的13B涡轮侧出动力系统主导了北海道街头直线加速赛事。在21世纪初，这辆车被改装为全管框架底盘，这套底盘是渡边桑通过邮购从美国RJ赛车公司购买而来的。零件到货了，而且五一确实，渡边先生松了一口气，在他的车间里做了一个底盘支架，把框架焊接在一起。虽然需要进行一些修改，但RX-7的车身面板还是基本吻合这套底盘的。
Over the years the car has been run with different engine setups and won many trophies, most earned on the now closed Sendai Hi-Land Raceway drag strip. Watanabe-san has also taken the car to Australia in the past, going heads-up with some of the quickest sport compact drag cars in the world at Willowbank Raceway during the Jamboree event.
多年来，这辆车使用过不同的发动机设置，并赢得了许多奖杯，其中大多数是在现已关闭的仙台Hi-Land Raceway drag strip上赢得的。渡边先生过去也曾开着这辆车去澳大利亚，在Jamboree赛事期间，在Willowbank Raceway上与世界上最快的一些紧凑型直线赛车齐头并进。
Today, the RX-7 is powered by a naturally aspirated 4-rotor engine
pieced together by Yashiro Engineering. Tuned through a MoTeC M800
engine management system, the custom ‘YR26B’ produces 600ps.
今天，RX-7由Yashiro工程公司组装的自然吸气四转子发动机提供动力。通过MoTeC M800发动机管理系统调整，定制的“YR26B”产生600ps马力。
The 2022 Option x G-Works Super Drag Festival was a memorable event for
Watanabe-san and his team. Not only did they set a new class record
early on in the event with a 8.707-second pass at 247.42km/h, but on the
very last run of the event they dropped their best ET to 8.559-seconds.
How good is that?! You can watch footage of the record pass here.
2022年Option x G-Works超级速度节对渡边先生和他的团队来说是一次难忘的活动。他们不仅在比赛初期以247.42公里/小时的速度以8.707秒的成绩创造了新的组别纪录，而且在比赛的最后一场比赛中，他们的最佳ET降至8.559秒。这个成绩真是令人叹为观止！
