Team America World Time Attack - ARK Design's BNR32 Skyline GT-R Part 9

by Eric Hsu

I realize it's been a long ass time since I've published an update, but they'll start rolling out again somewhat regularly after the new year. The car arrived safely back to Design Craft in September from the giant shipping mishap to China. Progress has been slow with Team American members busy with the remainder of the Formula D season, SEMA, the holidays, and new jobs (for several of us ex-Cosworth people). I never did completely finish the coverage on what happened up until we rolled into the shipping container so part 9 will continue directly from part 8.

World Time Attack Team America - ARK Design's BNR32 Skyline GT-R Intro Part 1

by Eric Hsu

The team and I have been hard at work with ARK Design's BNR32 Skyline GT-R. You may remember this car as the old XS Engineering BNR32 GT-R, but that was the distant past. ARK Design now owns this car and it is being rebuilt from the ground up. Follow us as we convert this car from the glorified street car that it was to the world class Time Attack car that it will become. The team only has until June to have this car built, tested, and loaded into a shipping container for Sydney's 2012 World Time Attack Challenge with a limited budget and limited man power. One last thing: this will be the last time you will see an RB26 in it and the last time you'll see this car blue.

World Time Attack Challenge 2011 Pro Class Controversies

by Eric Hsu

The Yokohama World Time Attack Challenge (WTAC) 2011 was a massive success for the promoters, competitors, fans, sponsors, and vendors alike. Ian, Nathan, Kyle, the announcers, and the volunteers who all make up the World Time Attack Challenge and Superlap Australia successfully put on the best damn Time Attack event anywhere in the world to date! But there were some controversies and I attempt to clear them up here.

Cosworth 4G63 Stroker Kit

Cosworth releases 4G63 Stroker Kit

MotoIQ Staff Report

A high power Mitsubishi 4G63 engine places enormous amounts of stress on various engine components including the heart of the engine, the crankshaft.  Cosworth has engineered a 94mm (2.2L) crankshaft that is 50%-80% stronger in critical areas than typical aftermarket parts.

Cosworth's 400th Subaru Engine

In 2006 Cosworth started the Performance Parts business based out of the Torrance, CA Champ Car and Formula Atlantic engine build and test facility. Today the product line has expanded to form a self sustaining stand alone business with a world wide customer base. With Subaru engines and components being the most popular product line, on May 19, 2011, Cosworth built its 400th Subaru engine.

Turbo: Once Round the Block

by Eric Hsu

Two videos after the jump of the development process of the 1986 Cosworth GBA 1.5L V6 engine. The video also covers the development of the ECU and car, but what interested me more was the 4 cylinder Cosworth BD that was built as a tester on the engine dyno and its failure mode. This was before the time of CAD, FEA, CFD, and all that computer mumbo jumbo. 25 years ago it was all about your past experience and empirical testing which is a lot closer to how things are done in most parts of the tuning parts market today.

Cosworth XFE ChampCar Engine on Dyno

by Eric Hsu

Cosworth's last CART/CCWS engine revs to 12,000rpm on the engine dyno with glowing headers and all. A 2.65L V8 that revs to "only" 12,000rpm with approximately 7.5psig of boost = 750bhp.

Tool Racing has their 1983 Williams FW08C-07 F1 car taken apart for fuel system repairs which means that half the car is taken apart. I really dig old race cars; especially ones with a winning history. Check out the pics inside for details.

VQ35 on the Engine Dyno


Several months ago when we had the VQ on the engine dyno at Cosworth, I snapped a couple of pics. Since I never got to work on engine dynos very much in the past, I thought it was way cool to see a street car engine that we [the mostly unibody car crowd] commonly build/tune/whatever on a professional grade engine dyno. The ease of working on the engine is nice: there are no cut arms, burnt hands, busted knuckles, and emanating under hood heat blasting you in the face like on a chassis dyno. The amount of data we can collect is ridiculous too.

In the US, we do not have transient dynos. I think Cosworth has 7 transient dynos in the UK, but that is the SUPER big dollar equipment for ...

Cosworth EC Pro Development

 

These last couple of weeks Ben, an engineer from Pi Research/Pectel, and I have been living and breathing 2008 Subaru Impreza STi. The Cosworth EC Pro is designed by the brains at Pectel UK (a division of Pi Research and sister company of Cosworth) for Cosworth. It is exclusively sale and use in the North American market so all you guys in Europe will not be able to purchase or use it (for now at least). There are enough differences between the European market STis and North American STis to make it a very impractical adaptation. For you Americans though, you will soon have the absolute most powerful plug-in ECU available in the...

Cosworth CA F1

 

I got some emails asking me what the Cosworth CA 2.4L V8 engine was/is/going to be. I'm sure the engineers at Cosworth UK will be detuning the engine a bit for lower cost and higher mileage, but in 2006 it was the highest revving and most powerful F1 engine at the time.

Cosworth Drag EJ257

 

Before I started working at Cosworth, the guys here were working on a "low budget" drag Subaru EJ257 engine program. The quotes are there because the term is relative. Low to one person may not be low to another. The budget was low compared to a real motorsport engine program, but probably considered high for the street car/weekend warrior crowd. EITHER WAY, PLEASE DO NOT CALL COSWORTH AND ASK FOR A DRAG SPEC ENGINE (unless you have 6 digits+ US$, not Japanese Yen of course). I'm not being a snob; I'm just saving you the pain of rejection. Anyhow, Cosworth was enlisted to build 2 engine programs: one gasoline and the other methanol. Pictured below is the methanol engine that made 1013...
