GT-RR partners with John Shafer
Monday 28th September 2009

It is with great pleasure that we announce GT-RR’s newest member of our team of GT-R specialists. John Shafer has recently joined GT-RR officially as our Master GT-R Tuner. John will assist our projects and clients all over the world with technical support and custom tuning. GT-RR has already had a successful history working with John on various projects and we are excited to have him as an integrated part of our team to even better serve our clients needs.

John as many of you may know was the R35 GT-R tuning guru behind the development of the Cobb AccessPORT for the GT-R. John was also the first aftermarket tuner in the world to collaborate on the reverse engineering team for the GT-R’s ECU during his time working for Cobb. Since then John continued to make advancements to the Cobb unit, personally writing every map for every AccessPORT around the world. John has also served as a liaison for nearly every GT-R specialty tuning shop in North America. Amongst all of this, John has also written a tuning guide for Cobb which teaches their dealers how to tune the R35.

We at GT-RR are proud to take our level of service to new heights by adding John whom many would consider to be the most respected and experienced R35 GT-R tuner in the world.

Additionally, as you may have heard, we are now offering complete car building services on both coasts of the US as well as remote computer tuning worldwide. John’s tuning facility, Akuma Motorsports of Morganville, New Jersey has become our official east coast partner for our client projects. If you need any work done on your car, regardless of where you live, we now offer more flexible and cost effective solutions than ever before.

Keep tuned to our website and blog as we release more information of our new 2010 Black on Black Street car project and the finishing power modifications of our Toyo GT-R project, both of which are being tuned by John out of our east coast partner facility.

Client support and technical questions for John can be emailed to john@gt-rr.com

Mine’s continue leading the way in terms of GT-R engine tuning with the release of their latest hardware upgrades. The Mine’s Super Camshaft Shore PRO is a full camshaft replacement for the VR38DETT designed to unleash the full potential of the engine in terms of response and power.

The Mine’s camshaft profile on the intake side is 256 degree duration with 10.2mm of lift. On the exhaust side there’s 264 degree duration with 10.5mm of lift.

Compare the Mine’s camshaft profile against the standard item which is 238 degrees / 9.56mm on the intake and 248 degrees / 9.88mm on the exhaust and you can see that the Mine’s set will clearly breath better.

These would ideally suit someone already running / considering turbo upgrades but even on the standard turbos you would see a concrete improvement once tuned. They’re full drop in replacements for both GT-R and SpecV GT-Rs.

Update: Pricing for the Mine’s Camshaft set is 138,000 yen.

Next up Mine’s have also released the final word in lightweight titanium midpipe for those who are chasing the ultimate response and power from their GT-R.

The Mine’s Titanium Straight Converter for Nissan GT-R removes the secondary catalytic converters and replaces them with two small resonators. The final weight reduction over the standard item is 9.8 kg (3.6 kg vs. 13.4 kg). The main pipe sections are 70mm into a pair of 110mm resonators. Then via dual 70mm pipes into a single 80mm collector.

Fitment is a simple bolt on affair and pricing is to be announced shortly. Again, stay tuned to the new Mine’s website for more details.

Update: Pricing for the Mine’s Titanium Straight Converter is set at 210,000 yen.

You may or may not have heard of the RH9 Club before, and if you haven’t what sort of rock do you prefer to live under these days? Anyway, RH9 Club is a group of workshops throughout Japan who are capable of building a GT-R capable of 9 second quarter mile passes in street trim.

While no R35 GT-R has stepped up to this realm yet, the RH9 Club does not simply ignore them altogether. Recently, in order to bring their collective expertise to the R35 owners of Japan they got together in Kyoto to work together on a set of tuning data that could be applied to the GT-R and be made available throughout the member workshop network.

The results achieved are interesting. Over at Phoenix Power’s workshop a test car was donated by Decide 226 workshop as a test mule. Originally tuned by Decide, in standard trim, the car made 513ps with 68.6 kgm of torque up from a baseline of 459ps. Tweaked with the RH9 collaboratively built map, it went on to make 550ps and 72kgm of torque.

Later, the same map was applied to the Phoenix’s Power GT-R, which is modified with a Blitz SBC-iD boost controller and SARD high-flow exhaust and results were 614 ps and 96.1kgm or torque.

Just how much boost was being used in these runs was not revealed, wastegate modifications were also not detailed. In the past Phoenix’s Power’s GT-R has run around 19.2psi running down to 13 psi by redline to achieve the 616ps it has previously clocked.

Interesting results out of Japan for relatively stock cars. The price for the upgrades are set at 168,000 yen plus 10,000 yen installation fee for 2008 model cars. An extra 60,000 yen fee is levied for the 2009 JDM cars which require some TCM tweaks apparently. Installation is available at any RH9 Club workshop throughout Japan.

Thanks to Mindlessoath for the email tip.

Kind of related to the previous story, although not featuring the exact same car, this short video presented by Sharif from Forged Performance shows what sort of technology and hardware goes into building and then tuning a quick Nissan GT-R.

Taking a look under that hood was interesting, these guys are making mid-10′s look pretty damn easy these days!

Great job Sharif you should do more of these.

Mine’s debuted their first version Nissan GT-R trunk and hood at Tokyo AutoSalon in January 2009 as part of the special Mines Spec-X 6.0 prototype, but since then further work has been done on both to produce these final products.

First up is the new Mine’s Carbon Bonnet – this OEM style hood has a few unique features. for one, it’s extremely light at just 5.2 kilograms. This is about a 57% saving over the standard item which was already quite lightweight. In making it light, Mine’s chose not to sacrifice rigidity and on the underside it is reinforced similar to the OE version. Secondly, the intake ducts have been redesigned and as you can see these original design intake ducts are much more integrated into the hood over the standard versions.

This hood is available with (651,000 yen) or without (577,500 yen) Mine’s Super Clear Coat protection at your local Mine’s dealers.

Next up is the new Mine’s Carbon Trunk Type I and Type II. You probably may think you’ve seen this before and that may be the case with the OE replacement Type I trunk lid. Take a closer look at the Type-II lid and you can see how Mine’s have integrated the lower spoiler mounts.

This results in cleaner airflow under the rear spoiler and subsequently lower drag and higher downforce at the rear. Best used with the Mine’s Complete Rear Spoiler which also deletes the center pillar.

The trunk lids are also exceptionally lightweight, saving 68% (4.5kg reduction) for Type I and 62% (4.1kg reduction) on the Type-II item. Price wise you’re looking at 399,000/462,000 yen for the Type-I with/without Super Clear Coat respectively. The Type-II is a little more at 451,500/514,500 yen with/without the Super Clear Coat.

Sweet, sweet carbon – you know you need these.
