Project 350z: Testing the MotorDyne Engineering MREV 2 Intake Manifold

by Mike Kojima

We are reaching the limit of easy bolt on performance gains with Project 350Z.  In looking over the offerings from MotorDyne Engineering, the folks that bought us the intake manifold spacer which made such an awesome difference. we noticed that they had a lower intake manifold plenum available for the VQ35DE that would work for both the Rev-Up and original intake cam only variable cam timing engines.

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 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 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.

Project 350Z - Testing Jim Wolf Technology C2 Camshafts

by Mike Kojima

So far we have tried some easy bolt ons like a manifold spacer, headers, high flow cats and exhaust on our 350Z all with good results.  Naturally at this point it is time to change camshafts to get more bolt on power out of our VQ35DE engine.  One thing that discourages many people from going this route is that changing cams on a VQ engine is quite a big job. Having two banks of cylinders and 4 cams is a lot of the reason.  It's not super hard technically but it requires at least a couple days of wrenching and some care has to be taken to avoid problems.

Time consuming or not, camshafts are the next logical progression in the evolution of Project 350Z so we asked our friends at Jim Wolf Technology or JWT to provide us with some of their excellent C2 cams.  We chose the C2 because they were probably the biggest practical camshafts that would work in the stock bottom end engine.

Project 350Z - Finding More Power with MotorDyne Engineering

by Mike Kojima

In looking for more low hanging horsepower fruit for Project 350Z, we decided to try an intake manifold plenum spacer from MotorDyne Engineering.  The 350Z's VQ35DE engine has a very thin intake manifold plenum that slopes toward the front of the engine to clear the low hood line.  Although this is good for styling, the engine would prefer more plenum volume and the flow to the front most cylinders is somewhat choked off due to the low overhanging plenum wall.

TESTED: Royal Purple Max Boost Octane Booster

by Mike Kojima

To be honest we were not big fans of octane boosters.  In the past, we have not been able to get good quantifiable results with them over the years. Older boosters ate up the fuel system or left weird deposits on the plugs and chamber. Engines that usually need higher octane are generally expensive so we have always just used racing fuel in them,  Pump gas with conservative tuning for street cars and race fuel for race cars.

Meanwhile, Royal Purple had been bugging us about testing some of their new Max Boost octane booster.  They told us that it would give us 3 points in octane for sure and burn clean.  Not being too enthusiastic about octane booster in general we let it sit around for about a month.

Nerd’s Eye View: 2013 Performance Racing Industry Show

by Wes Dumalski 

If you were one of the more than 40,000 sets of eyes that had a chance to read through our first PRI article, here is the sequel. In our previous article we slaved from 8:00AM to 1:30AM to bring you 16 pages of goodness! That meant a whirlwind tour through specific booths and a map of what we needed to cover from start to finish. It also left ZERO time to walk around the show and soak it all in on Thursday. So on Friday and Saturday we strolled to bring you what WE thought was cool, the things that caught our eye, our Nerd's eye....

350Z - Boosting Power With DC Sports and Berk Technology

by Mike Kojima

In the past installments of Project 350Z, we took a look at getting the car's suspension and brakes up to snuff.  With the car handling and stopping well, we turned our focus to freeing up some more power.  Since the car is mostly a budget track day beater, we decided against forced induction options for now because making a high power forced induction motor reliable under continual hot lapping conditions is a somewhat expensive proposition.

To keep a decent budget balance, we decided to focus on some good bolt on's to see what we could get from our 350Z.  For our first step we decided to free up the exhaust side of things with headers and an exhaust from DC Sports and free flow cats from Berk Technology.

Nerd's Eye View: Inside Fredric Aasbo/Papadakis Racing's Amazing V8 eating 2AR Toyota Engine 

By Mike Kojima

A couple of years ago, a lot of knowledgeable people, myself included declared that the turbocharged small displacement 4 cylinder engine was dead in the sport of Pro Drifting.  Dead, uncompetitive and obsolete.  We sung the praises of the latest new generation of domestic V8's like the Chevy LS, the Chevy SB2 and the Ford Coyote.  For a while it seemed so even though others like our own Eric Hsu predicted otherwise.

This year things are changing, turbochargers are coming back to the delight of fans and challenging the rule of the V8.  One of the most intriguing and successful applications of new turbo technology is the Toyota 2AR engine developed by Papadakis racing and driven by Fredric Aasbo.

The 2AR is a 2.5 liter all aluminum inline 4 that is both lightweight and stout at the same time.  Papadakis racing has proven that it can operate reliably for a long time at exceedingly high power levels.  It's taken about 2 years for Papadakis racing to hone and develop the 2AR into the potent package it is today and the story and parts behind it are interesting indeed.  Check it out!

Project FR-S: More Power Everywhere with an Intercooler from Innovate Motorsports

by Mike Kojima

With good handling and unbelievable brakes, our FR-S is really hurting for power. In one of our last stories we added an Innovate Motorsports supercharger and got a healthy boost of power across a really wide powerband, we gained power literally everywhere from idle all the way up to the redline.  We still wanted more so the next logical step was to add an Intercooler and run a little more boost all with parts from Innovate Motorsports.

As a bit of great news we were informed that the Innovate Supercharger has earned a CARB EO so in addition to making nice power, the Supercharger is now 100% smog legal!
