A common sight at a drifting event it's good to see a few more late model 4-cylinders street cars at the drags. This SR20 turbo powered Nissan S15 car has strong trap speed so expect times to keep on improving.

Nissan TB48 turbo Torque Monster Dyno tuning a Nissan Patrol TB48 4.8L six. The engine is now rebuilt with forged pistons and rods and features a custom JPC turbo at 10psi Boost and MoTeC EFI. Not built for outright power, but instead good throttle response and reliability the engine will be going into an off-road dirt truck. Initially making close to 600Ib.ft at just 3000rpm, torque was backed off for the truck's first shake down runs. A final figure of 559hp was achieved, not bad for a low Boost application.

A long-time customer of Powertune Australia, Ryan sports Powertune Australia's Stage 3 upgrade package for SR20DET on E85. Check out the link to the Powertune blog to catch a photo and a full write-up on what's in a Powertune Stage 3 Upgrade for SR20DET on E85.
Now for the wordy part on Ethanol Flex Sensors and Wideband Controllers...
Ethanol Flex Sensor - The Ethanol Flex sensor Is a device that can be fitted along the fuel lines of a vehicle that will be tuned to run on any mixture of ethanol based and octane based fuel.
Traditionally, vehicles were tuned on straight octane or straight ethanol only. Recent years have seen advanced ECUs support multiple fuel mapping which allowed switching of fuel maps to run on different fuel types, however this required dumping of fuel when making the switch, meaning inconvenient switching between fuel types.
The Ethanol Flex Sensor overcomes this by allowing a knowledgeable tuner to effectively tune on both fuel types and allow the ECU to handle transitional changes in the fuel and compensate accordingly.
This not only offers convenience in being able to run whatever fuel is available, it also offers a more reliable tune for those who wish to run primarily on ethanol. Ethanol content is quite inconsistent between bowsers so a straight ethanol tune from content in one bowser might not be ideal for the ethanol content from another bowser. By having an intelligent degree of compensation in the ECU, a flex sensor will allow the ECU to tune according to whatever ethanol content is being used.
As is seen in this video, Ryan currently has an ethanol content of E78 in his fuel lines so the tune on his ECU will compensate accordingly to run optimum on that level of ethanol.
Wideband Controller - A wideband controller is simply a unit that allows real-time trimming of fuel during the combustion process. This results in better fuel economy, smoother drive experience, absence of fuelly smells, absence of black soot buildup, better idle and cleaner tune.
A number of good ECUs can utilise a wideband controller. As a result of the Haltech ECU and wideband on Ryan's S15, his tune runs spot-on consistently and avoids all the negative "race car" experiences.
Nissan Silvia Military 6666 Customs - XCAR
Sataomi Nakawatase has a very particular style. He loves military iconography and the feel of old factories and has put that into his work. His Nissan Silvia has been customised and looks like a proper road tank.
This beast draws a lot of attention wherever it goes but can still tear up the track and drift with the best of them.
Sataomi describes the car as robot-like. It features rocket-bunny aero parts, a Greddy turbo charger, suspension by Stance Japan and Mickey Thompson wheels.

RH9 R32 GTR - Tassie Drags
OK now seems to be allot of GTR driving experts on here who have all owned and driven a 1000hp drag car.... the car was having issues namely with the gearbox and gear selections hence some of the causes of the dramas. But you knew that didnt you!
