原標(biāo)題：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.

在上個月的Option x G-Works超級速度節(jié)上，兩輛FC3S馬自達(dá)rx -7在中央賽道的維修站引起了我的注意。雖然這兩款車有一些相似之處——比如它們都來自北海道——但在它們一塵不染的白色車身下，它們是兩臺完全不同的機器。

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.

單單看這輛車的正臉，你并看不出這輛車與我們在Speedhunters中展示的其他調(diào)諧風(fēng)格的FC3S有任何不同之處。但當(dāng)靠近swart /Zeroyon Factory RX-7時，你就會察覺出那些只能在專業(yè)打造的直線加速賽車中找到的細(xì)節(jié)。

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和印第安納輪胎-——向后滑出29×11英尺，到位！平后翼和降落傘，到位！隨處可見的聚碳酸酯窗戶，到位！。帶換檔燈的5英寸轉(zhuǎn)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.

與參加超級速度節(jié)的大多數(shù)其他賽車相比，這臺馬自達(dá)看起來相當(dāng)“正?！保吹骄薮蟮膫?cè)出口排氣從右側(cè)前擋泥板冒出，我就知道引擎蓋下的什么東西絕對不能用“正?！毙稳?。

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的主人兼司機Akira Kato，熱情地向我展示了他的FC RX-7的構(gòu)造，后者得益于轉(zhuǎn)子發(fā)動機的功勞非常強勁。您先看看Garrett GT4508R渦輪增壓器(具有80mm壓縮機入口)與拳頭大小的比較。考慮到渦輪的大小，我很驚訝地發(fā)現(xiàn)它甚至不是最大的Garrett渦輪;據(jù)悉，寬達(dá)106mm的版本即將上架。

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.

發(fā)動機本身是JC Eunos Cosmo強化過的3轉(zhuǎn)子，但加藤先生投入了更多，包括完整的推進(jìn)裝置和一氧化二氮動力系統(tǒng)來使這臺馬自達(dá)“移動”。根據(jù)該團(tuán)隊的說法，這款發(fā)動機的紅線為9200轉(zhuǎn)，轉(zhuǎn)速為950ps，是RX-7離開馬自達(dá)工廠時的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).

介于這款RX7采用了Jarico變速箱和R33日產(chǎn)Skyline GT-R后端底盤，它的重量并不輕，但加藤先生在這款車上取得了不錯的進(jìn)展，今年早些時候以233公里/小時的速度跑出了9.052的最佳成績，直接沖擊著8秒大關(guān)。這個速度足夠快，以至于可以在日本直線加速錦標(biāo)賽的“RWD超過2.5L和3轉(zhuǎn)子發(fā)動機”級別中拔得頭籌(總體第四名)。

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賽車當(dāng)天在中央賽道運行的視頻，但你可以在茂木今年早些時候的一次活動中看看這輛車的身姿，聽聽三轉(zhuǎn)子高亢的聲浪。

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.

另一臺在幾周前極速沖入中央賽道的RX7 FC3S則是日本最著名的國產(chǎn)直線加速賽車之一。它的所有者是如假包換的zeroyon OG。自1986年它出廠以來，就一直在渡邊的手下為直線加速賽而改裝進(jìn)化，所以我無法判斷誰才是真正的傳奇-渡邊還是馬自達(dá)。到現(xiàn)在為止，他們肯定已經(jīng)形成了某種共生關(guān)系，所以他們都應(yīng)該得到同樣的高度贊揚。

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.

在這段關(guān)系的前10年，RX-7用強悍的13B渦輪側(cè)出動力系統(tǒng)主導(dǎo)了北海道街頭直線加速賽事。在21世紀(jì)初，這輛車被改裝為全管框架底盤，這套底盤是渡邊桑通過郵購從美國RJ賽車公司購買而來的。零件到貨了，而且五一確實，渡邊先生松了一口氣，在他的車間里做了一個底盤支架，把框架焊接在一起。雖然需要進(jìn)行一些修改，但RX-7的車身面板還是基本吻合這套底盤的。

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.

多年來，這輛車使用過不同的發(fā)動機設(shè)置，并贏得了許多獎杯，其中大多數(shù)是在現(xiàn)已關(guān)閉的仙臺Hi-Land Raceway drag strip上贏得的。渡邊先生過去也曾開著這輛車去澳大利亞，在Jamboree賽事期間，在Willowbank Raceway上與世界上最快的一些緊湊型直線賽車齊頭并進(jìn)。

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工程公司組裝的自然吸氣四轉(zhuǎn)子發(fā)動機提供動力。通過MoTeC M800發(fā)動機管理系統(tǒng)調(diào)整，定制的“YR26B”產(chǎn)生600ps馬力。

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超級速度節(jié)對渡邊先生和他的團(tuán)隊來說是一次難忘的活動。他們不僅在比賽初期以247.42公里/小時的速度以8.707秒的成績創(chuàng)造了新的組別紀(jì)錄，而且在比賽的最后一場比賽中，他們的最佳ET降至8.559秒。這個成績真是令人嘆為觀止！
