Project 350Z- Testing the AEM Induction Cold Air Intake

by Mike Kojima

In our last trip to the dyno, we tested  AEM's Short Ram intake on our 350Z.  We were surprised to find a small but definite power increase over another leading intake that was already on the car.  Since AEM makes a long runner Cold Air Intake as well as the Short Ram, we decided to test that as well as an interesting contrast between the two vastly different intake designs.


 

Project E36 M3: Part 3 - Borla ExhaustProject E36 M3 (Silver): Part 3 - Uncorking the M3 with the help of a Borla Cat-Back Sport Exhaust.

by Billy Johnson

E36 M3s are notoriously difficult to make power out of while staying naturally aspirated and we are constantly in search of the best bang for your buck since a lot of money can be spent for little to no gains in power.

While this E36 M3 was previously used to test various intake components and eventually cams, the quiet 15 year old stock exhaust was left untouched.  With help from our friends at Borla, we dive into the exhaust half of the equation to free up some more ponies without breaking the bank while making our car sound more like an M3 should to better reflect its performance.


 

Project 350Z- Increasing Oil Capacity with Jim Wolf Technology

by Mike Kojima

We have been working on getting more power out of Project 350Z's VQ35DE engine in our latest series of articles.  With success coming bit by bit, we decided that we had to give the oiling system a little help.  Some 350Z's with highly modified suspension and sticky tires have suffered from engine oiling issues when driven on the track hard.  The oil had simply sloshed away from the pickup under hard cornering allowing the oil pump to suck air.  Since engine bearings are made of soft metal and depend on a hydrodynamic layer of pressurized oil to prevent damage, any interruption of oil pressure caused damage very quickly.


 

Project 240SX Land Speed Racer:  Better Living through Volumetric Efficiency

by Chuck Johnson

After removing more than one cylinders' worth of displacement from an SR20DET, the need to improve the volumetric efficiency of our engine through forced induction became absolutely critical. In other words, if we were going to have any chance at breaking land speed records, we'd need a badass turbo system and there was simply no room for scrimpin' here.  So, we stocked our turbo system with the best components we could find:  A Borg Warner EFR turbo, dual Turbo Smart Hyper Gates, and a stainless steel Full Race Motorsports turbo manifold.  Then, we made all the right connections with Earl's Performance Products.


 

Blacktrax Performance S2000 Motorsport Makeover: Part 1 - Basic Chassis Preparation

by Edward Hu

To start off 2014, the TunerPlayground and BlackTrax Performance team have huge plans for overhauling their time attack Honda S2000, nicknamed “Irene.”  In the past few years, Tom Tang, TunerPlayground founder, has showcased just how capable he and the car are at events such as Global Time Attack at Buttonwillow, where it ran a 1:56 in the CW13 configuration, all while retaining street-driven status. Above is a “before” photo.

This year, however, Irene is going all out. TunerPlayground Motorsports is aiming to participate in wheel-to-wheel, hill climb, and time attack events. These include, but are not limited to: NASA USTCC, Honda Challenge, SCCA Run-Offs, Global Time Attack, Redline Time Attack, Super Lap Battle, MotoIQ MPTCC, Hoopa Hill climb, and eventually, even Pikes Peak.


 

Project G20: Making it Stick With APR’s Wing and Splitter

by Steve Rockwood

Project G20’s an aerodynamic disaster. It’s blockish shape leads to a car that makes masonry look sleek. As a result of poor aero combined with suspension balance in line with “loose is fast, don’t be a <sissy>”, we needed all the APR aero help we could to tame this bronco.


 

Project [Rotary] FD RX-7: Part 4 - Turbo System

by M-P Spierer

Designing and installing the turbo setup is one of the most enjoyable aspects of any build. There are many decisions to make when planning out a turbo setup and each decision has significant effects on subsequent decisions. It is a balancing act of desired goals and undeniable trade-offs. Many questions need to be answered like, am I looking to maximize mid-range response or top-end power? And, how much response will I be giving up if I choose one turbine housing A/R over another? These are questions that have different answers for every build. For this RX-7 we are trying to maximize response around a specific power limit without breaking the bank.

Project E36 323is: Part 7 - Cleaning Up The Office with Driven Steering and BMWPedals.com

by Jonathan Lawson

There’s something to be said for having a comfortable and productive work space, and that goes for your regular work desk or your driving office. We decided to clean up the look and feel of the Project E36 323is office with a new suede steering wheel from Driven Steering mounted to a MOMO hub adapter, and with some new pedals from BWMPedals.com, all as a way to increase driver focus, and to simply make it look a little better.


 

Project FR-S: More Rear Suspension with Cusco and Whiteline

by Mike Kojima

In our last segment we brought the front suspension of our FR-S up to the latest top standards with new parts developed for the car since we started developing our project.  Now it's time to bring the rear suspension up to snuff with some of the latest parts now out for the car.  Since we started out project, Cusco and Whiteline have come up with more parts for the rear suspension.

Our suspension had first gotten done well over a year ago and we used Suabaru STI parts in the initial stage.  We used Cusco adjustable lower arms and some Whiteline bushings and their first generation of rear swaybar.  As we are running tires much bigger than stock, (265 vs 215), the additional grip was causing a lot of body roll even with our KW coilovers and upsized swaybar.


 

Project 350Z - Testing AEM's Short Ram Air Intake

by Mike Kojima

When we first got Project 350Z as a well used and beat up car, one of the mods the car came with was an Injen Cold Air Intake.  Since Injen intakes have a pretty decent rep we simply left in on the car.  However, when we installed the intake manifold spacer, we noted that the manifold was full of dirt and that our engine was a little low on compression for the amount of miles that it had.
