Well the summer in Montana has come and is quickly on its way out. Although we will be back to enjoy the winter it was time to get the Nissan 240sx KA24-T drift car down to a suitable environment in order to keep doing what it was built to do. The trip south began the beginning of September. The goal was to make it to Seattle, WA and then drive down the coast on Hwy 101, enjoying the sights and some spirited driving on all of the twisty roads. There isn't much to say besides the fact that I had a perma-smile on my face the whole time and I'm sure put a smile on those faces whom I passed! Be advised that driving a car 2000 miles Below are some of the highlight pictures from the trek.
The modern turbocharger has come a long way in the last 10 years, with new lighter and stronger materials becoming available the performance and efficiency of turbochargers has vastly increased. Materials such as Titanium used in turbine wheels and forged Billet CC’d Aluminum used in the compressor wheels are now becoming the standard.
At Brewed Motorsports we decided to use our S13 track car to do some testing on one of the hot new Borg Warner EFR turbos, the EFR 6258 to be exact. The new Borg Warner EFR series turbos have taken a large step above and beyond all the competitors.
The EFR turbo charger series utilizes titanium-aluminide turbine wheels. These state of the art turbine wheels are half the weight of the typical inconel turbine wheel found in 99% of all other turbo chargers. The reduction in weight or rotating mass vastly improves low-end response and spool time creating higher boost levels at lower engine speeds greatly reducing lag. The renovation does not stop there, the compressor wheel is forged milled aluminum creating an extremely light and strong CC’d compressor wheel. Of course Borg Warner’s Extended Tip Technology has also been implemented on the EFR series turbo chargers increasing compressor efficiency even more. Borg Warner does not stop at the wheels either, the internals have also been redesigned for un matched performance and durability. Dual Row Ceramic Ball bearing w/ M50 races and metal bearing cage can be found at the heart of every EFR turbo. This ensures thousands upon thousands of boosted miles for your project. For those serious racers using anti lag systems these bearings will not fail under the extreme heat and pressure seen in both drag and rally style anti lag systems.
We decided to use our KA24 powered S13 to do some testing on the Borg Warner EFR 6258. Thanks to the custom Full Race turbo manifold we were easily able to switch out the old worn out Garrett GT turbo for the new EFR 6258. A simple mod to the downpipe to accept the 3” V band found on the EFR and we were ready for some tuning and then headed to the track for real world testing!
Check out short video for the EFR transformation and quick preparation for the track. Of course stay tuned for our full review as well as a new videos from Fire Bird Race way drifting with the new EFR turbo.
The Korean Auto Show may not have been comparable in size to the SEMA or PRI shows in the states, however the Korean manufactures as well as imports from Japan, United States and Germany did not hold back. With great booths, displays and models (both cars and Korean women) the 2011 Korean Auto Show is the perfect place to get a feel for the OE Automotive market in South Korea.
With an all but complete lack of any aftermarket manufacturing companies present at the show a motorsports enthusiast may feel some disappointment upon arrival. This feeling is however short lived as many manufactures not only brought out new prototypes but also many different factory built race cars. Everything from light weight GM FWD 4cyl powered road race cars to a fully prepared Hyundai Genesis Coupe. Of course the female models kept the cameras flashing and the Korean men on edge and blushing.
Enjoy the pictures and keep an eye on Korea where a unique (for lack of better terms) Tuner scene is growing by the second. Special thanks to my good friend Youngdae Kim of ProConcept for inviting me to the show.
