Turbo Tech:  Turbo Bearings

by Khiem Dinh

We like turbos at MotoIQ.  Why?  In the phrase made famous by Tim Allen, "more power!"  In order for a turbo to cram air into an engine, it has a pair of wheels and a shaft spinning at incredible speeds.  Depending on the size of the turbo, they can spin anywhere from 100,000 rpm (big turbos) to 300,000 rpm (small turbos).  300,000 rpm equals 5000 revs a second.  Put another way, if you rolled a compressor wheel on the ground, it would go about six football fields a second.  That's about 1.7 times the speed of sound.  Wrap your head around that!

Fredric The Great, a Look Inside the Papadakis Racing Scion tC of Fredric Aasbo (VIDEO INSIDE)

By Mike Kojima

We had never heard of Norwegian Fredric Aasbo before Formula D's Long Beach Round last year.  Suddenly out of nowhere a red privateer Toyota Supra driven by a guy whose last name we could not pronounce almost stood on the podium bettering the efforts of many seasoned and well backed Formula D veterans.

Project V8 RX-7: Part 4 - Dressing the E-Rod

By Jeff Naeyaert

So we’ve got our E-Rod kit, unpacked everything and laid it all out, but curiously missing are all the spinny things that go on the front of the engine—more specifically, the alternator, power steering pump, a/c compressor and the other pulleys and tensioners necessary to keep everything playing together nicely.

Professionally Awesome - A look inside Professional Awesome's EVO VII Street Class Time Attack Challenger

By Mike Kojima

We first spotted Team Professional Awesome's EVO VII at last year's Redline Time Attack at Cal Speedway.  To be honest, it was not the car that first attracted us but the name of the team.  After looking the car over, we knew at once that this was a well constructed and balanced car.

Suspension Techniques BMW E36 M3 suspension tested!

ST Suspensions'  BMW E36 M3 Street Suspension Reviewed

By Mike Kojima

When Formula D and road racing pro Mike Essa needed a street suspension for his daily driver BMW E36 M3 he was not looking for the latest and greatest track shredding stuff, just something where he could comfortably run a lower ride height with firm control that could replace the old 140,000 mile worn out stuff on his car.

Compression Ratio - A Look From The Thermo Side

By Khiem Dinh

You want more power and probably better fuel economy due to ever increasing fuel costs.  The government wants lower emissions.  So how do you achieve all those?  Increasing the compression ratio of the engine is one method.

Project Infiniti G20 Racecar - Making It Stop, Every Time

By Martin Gonzales & Steve Rockwood

Loud engines, big horsepower, gratuitous tire smoke, and high cornering speeds are why we love and watch motor sports. Most people, when they watch racing on TV, listen for the engines, stare at the gruesome crashes or marvel at the speeds drivers carry through the corners. However, much like the scrappy player on a basketball team that gets all the rebounds and never scores, brakes just don't get the attention they deserve.

Project Honda EJ Civic: Initial Driving Impression

By Annie Sam

Standing in the hot pits of Buttonwillow Raceway Park, I could still recall the first time that I had taken my little Honda Civic to the racetrack back in the winter of 2002. We were at the Streets of Willow, in Lancaster, California. Nine years and 200,000 miles later, my baby was battle scarred and war torn with years of daily abuse, adding to the list of things that plagued the back of my mind as I prepared for my hotlap at Buttonwillow. Slipping clutch? Yes. Faded front brakes? Yes. Nonexistent rear drums? Yes. Blown shocks? Probably. Be sure to check out the video at the end of the article!

Project Nissan 350Z Part One: Installing an ACT Clutch and a Nismo LSD

By Mike Kojima

Our friend Sera is a stuntwoman by trade who does a lot of driving for movies, commercials and TV.  If you see a woman driving in a car commercial, chances are it's Sera. She also does track days with NASA and is into drifting.  She had bought a Nissan 350Z to use as a car to do some track days and also for her to practice her stunt driving and drifting.  The trouble is as soon as she hit the track, she encountered some problems.

Tuners: Test Your Injectors!

Tuners: Test Your Injectors!

By Jim Wolf

Oh my God, what a mess this has become! As race engine development moves forward, aftermarket fuel injectors seem to be moving sideways. About ten years back a trend started to modify stock injectors for higher flow rates. This was done by either drilling out the spray orifices or removing the spray plate all together! While some of the companies attempting this seemed to be making a serious effort, actual flow testing in many cases would indicate otherwise. No doubt someone will eventually figure out how to do this accurately, but in the mean time, they at least need to be willing to do actual flow testing, static and dynamic on each injector (no duplicated flow sheets please). Add this twist to the already diverse methods used to state injector flow values and you have a bit of a mess to sort out.

Project V8 RX-7: Part 3- Inside the GM LS3 Cylinder Head

Project V8 RX-7: Part 3- Inside the GM LS3 Cylinder Head

By Mike Kojima

In the last edition of Project V8 RX-7 we looked into the bottom end of our EROD LS3 engine to find that the modern Chevy V8 is a far cry from the old small block Chevy of years past.  Lately on some forums that cater to import performance, there has been a huge backlash against the LS swap, particularly into Nissan S chassis and RX-7’s.  All sorts of bleating noise from uninformed sheep decry putting “NASCAR” engines and the like into the S chassis. Purists claim that putting in a domestic engine somehow is making their favorite cars all the same and causes them to lose their soul and other things not defined by logic.  Such is the garbage cluttering the net these days.  Like many FFF facts on the interwebz, their are many fundamental inaccuracies to these statements.

Project EVO IX Part 8: Tuning for AEM Water Injection

Project EVO IX Part 8: Tuning for AEM Water Injection

By Mike Kojima

When we last left our project we had just installed some Cosworth M2 cams and had tuned around that with excellent results.  Some time ago we had installed an AEM water injection system and warning monitor system and had been running the water, mostly just for thermal control when running hard.  We knew to get best results we would have to tune our ECU to take advantage of the detonation suppression capabilities of water and to nullify the water's quenching properties which reduce power.

Project Toyota Tundra- Installing the TRD Supercharger Part 1

By Mike Kojima

When we last left off on Project Tundra we had installed a TRD cold air intake and TRD exhaust system.  We were enjoying the high quality, warranty friendliness and smog legalness of our TRD factory engineered performance parts.  However being how we are we still wanted more.  In our search for the ultimate tow and work vehicle, we obtained one of TRD's awesome supercharger kits.

Low Cost and Effective Head Work

Low Cost, Effective Headwork!

By Mike Kojima

My race in the inaugural MPTCC race ended with a bang in the practice before qualifying as my SR20VE decided not to cooperate in a big way.  Tearing down my engine afterward I found that one of the exhaust valves had lost its head.  Fortunately the valve head did not bounce around in the combustion chamber and cause more damage, probably because I had shut the engine off and pushed in the clutch the second I felt the power fall off.

Project EJ Honda Civic

By Chuck Johnson

You're probably wondering what this busted ass Honda Civic is doing on the virtual pages of MotoIQ. I mean, it's far from the flawless presentation of MotoIQ's usual project cars and lacks the engineering luster to be excusable like Coleman's innovative crap cans. Instead, this Civic's clear coat is peeling off and almost every panel has some kind of battle wound on it… but every gear head has a story about the car that was their first love.

Project Hyper-Miler Part 1: Introduction

By Steve Rockwood

Let's face it: the days of cheap fuel are over.  Whether you want to blame Wall Street, the government, democratic demonstrations in the Middle East, OPEC, hippies, China, or the soccer mom next door; the fact remains that if your buddy tosses you a five spot for gas money, you're more likely to punch him in the face than thank him.  And everyone understands a punch in the face.

Ask Sarah:  Hi-po Eclectic Pistons

By Sarah Forst

I was at a car meet and overheard someone talking about hi-po eclectic pistons or something like that.  I didn't want to ask him about them because everyone else seemed to understand what he meant.  Are these high performance pistons?  How are they different from regular pistons?
