anti lag rocket beyond the dyno

External Combustion Rocket Anti Lag System + JDM Spec C Impreza STI

By Eric Hsu 

The external combustion anti-lag "rocket" combustor was used on the factory Prodrive built WRC STi Subaru cars to improve the EJ20 engine's inherent mediocre torque and engine response. The rocket is so good that a version of it is still in use today in the 2012 Japanese Super GT GT300 STi BRZ which also uses an EJ20. Last time I wrote a teaser article, but this time we'll take a look at some of the details of the rocket combustor anti-lag system as it applies to my buddy Ben's JDM Impreza STi Spec C street car over in the UK.

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.

External Combustion Rocket Zero-lag Teaser 

by Eric Hsu

On the other side of the world is a lush green island with some of the brightest minds and most creative people in the world. They gave the world the Beatles, the universal joint, the Rolling Stones, Cosworth, the Smiths, Aston Martin, the wind tunnel, James Bond, bangers and mash, stainless steel, Depeche Mode, black pudding and of course, fish and chips. England is the little island that's given the world quite a bit. Now (or actualy several years ago in WRC), they give us external combustion anti-lag technology. Well they haven't quite given it to the world yet, but here it is in the first working street driven Subaru STi that belongs to my buddy Ben who's the best engine calibration engineer that I know.

Project Gen 3 STi: Testing the COBB AccessPORT

By Wes Dumalski

As it turns out owning a project car is not easy! First and foremost these are real cars owned by real people that pay for them with their own money. Life as well as vehicle practicality and reliability have ways of getting in the way of project car progress and/or completion. Take our Gen 3 GR STi project for example... We had had the car repainted, put back to stock all just so we could start fresh. OK so that is a total lie, the real story is that the previous project car was sold by the owner after blowing up it's totally stock motor on more than one occasion...

Adventures in China & Hong Kong, Part 1

by Eric Hsu

Last month I took a trip to Guangdong, China and Hong Kong to train a customer to use the Cosworth ECPro ECU and software suite. I had no idea what to expect in China. It was to some degree what I expected being a developing country, but it was also good to discover that street car tuning is alive and kicking. Track days are massively gaining popularity and there's even a touring car race series.

Beyond the Dyno - Rotary Love 16X

By Eric Hsu

I love rotary engines even though I do not currently own a rotary powered vehicle. I'm just taking a break I suppose. I'm all about 6 cylinders at the moment, but I still love rotaries. After the jump is why I love rotaries, Hydrogen rotaries, and some information on the up and coming "big block' 16X Mazda rotary 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.

Ask Sarah: I Need More Track Time From My Water Injection System!

By Sarah Forst

I have a 1996 Mazda Miata with a Jackson Racing MP45 supercharger and an ECU controlled Aquamist water/methanol injection system.  The water tank I use is about 3/4 gallon in size, so when I fill it up with straight windshield washer fluid (no additives, just water and methanol) I'm running the tank dry well before my 30 min. track session is complete.

Nissan's MR16DDT 1.6L Direct Injection Turbo Engine

by Eric Hsu

Nissan's exciting new MR16DDT engine has all of the features and stats that you would want in a kick ass engine. It also sounds like it may have what it takes to be Nissan and/or Renault's entry as the GRE (global race engine). Imagine seeing this engine in the back of an F1 car...

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.
