Not content to let the matter rest after their first foray into the Nissan GT-R exhaust market, PowerCraft have revised their Hybrid Catback Exhaust system to this bigger and better version.

Using a setup of user controlled valves, the exhaust can operate in tame daily driver mode when you need it to be. At a flick of the switch though you can instantly be as obnoxious as your right foot wants.

The system includes a 90mm straight pipe main section into the rear muffler set up. The exhaust then branches into 70mm piping to feed 4x 115mm titanium outlets. This is a 10mm increase over the previous version which seemed quite restrictive in comparison.

Price is 388,500 yen inc tax in Japan.

I’ve always had a fascination with this car since I first checked it out at Superlap 2009 back in March last year. Maybe it harkens back to my black R34 GT-R or maybe it’s the absolute raw focus and single mindedness of this build. It’s probably both mixed in with the fact that it’s happening in Australia versus somewhere in Japan where you’d normally see a R34 this insane.

This year the Superlap event has gone global and taken new form as the World Time Attack Challenge and Hi Octane are getting the car ready with some interesting updates to improve grip in the corners.

With thanks to Aeromotions, they’ve upgraded to an active rear wing that gives them more downforce in the turns but less drag down the straights. They’ve also updated the front aero with a rather impressive (and by that I mean massive) looking splitter.

Other changes to the suspension will hopefully make the car a little easier to control especially now that it’s making even more power even earlier due to an E85 tune.

The World Time Attack Challenge has attracted competitors from as far away as the US and Japan this year so there’s going to be some stiff competition. For GT-R fans this will be the horse to back I’m betting. Can it slay the finely tuned Evos of the world though? We’ll see this coming May…

For now I highly recommend you turn your speakers up and listen to this crazy RB26 as it preps for the coming events in the video below…

For maximum efficiency when using Willall’s front mounted transmission cooler, they’ve designed this pump upgrade that will replace the supplied VDO item. This Propump, as they’ve called it, manages to circulate the entire volume of transmission fluid through the front mount cooler every 40 seconds. In testing, the guys have found this unit can assist lowering temps by as much as 35 – 55 degrees F.

The kit will ship with all components necessary to fit it including the high performance pump assembly, control electronics and CNC machined mounting hardware.

To spec out a new WR35TC-F with the Propump will run you an additional $395. Existing WR35TC-F owners should stay tuned and expect an announcement on what they can do for an upgrade some time in April.

When a big exhaust just isn’t enough, when you need to make maximum possible horsepower, and when you need to do all that and wake up people in the tri-county area you might want to check out SSP’s new mammoth 102mm exhaust.

Perfect for the track GT-R, this exhaust features 102mm diameter mandrel bent 304 grade stainless main section which branches into dual 76mm high flow mufflers on each side and finally into quad 127mm exhaust tips.

The guys use it on their record breaking drag GT-R so it’s certainly proven it can support the horsepower. It retails at $2,999.

It’s been a while now but the previous quarter mile record (at an officially sanctioned drag strip that is) of 10.31 @ 131mph was destined to fall and fall it has! The GT-R nudges its way ever closer to the 9 second mark thanks to SSP, who built the car, and Jack Cecil from HP Logic who tuned it, by running a 10.236 @ 136.02 mph in Florida this week. A video of the pass is below.

On the same night the guys also recorded a 10.52 pass at 141.15mph in their white GT-R.

Certainly getting quicker and quicker, will we see 9 seconds sooner rather than later?
