Oil Pump Blueprinting

By Martin Gonzales and Mike Kojima

What is as important to your engine's health as your heart is to your own body?  If you guessed the oil pump then you are absolutely correct!  Like your heart, your oil pump circulates the engine's life blood, oil, around to critical components like your engine's bearings and valvetrain.  These parts like parts of your own body would only last seconds without a continual supply of pressurized oil.

AEM No Weld O2 Sensor Mount

By Mike Kojima

Being able to quickly attach a bung for a wide band 02 sensor is a big pain in the ass.  I know a lot of you have probably tried to help a friend tune their car.  No matter how many times you told them to have an O2 sensor bung welded into their exhaust before they show up at your place, then they arrive and you ask them where it is, they blankly look at you and go "what?"  I know this happens to me all the time.

AEM Performance Electronics Water Methanol Injection System Evaluation

By Mike Kojima 

AEM gave us their latest version of a water methanol injection system and we agreed to install it on Project EVO IX.  The AEM system uses a powerful high pressure, 6amp, 72 watt 150 psi pump.  This is important because on a turbo car, the water system has to work against the boost pressure so a 20 psi windshield washer pump will actually not pump any water at all at 20 psi of boost unless the water tank is boost referenced. The pump also features chemical resistant fluroelastomer EDPM seals and a santoprene diaphragm so as not to be phased by ethanol or methanol in any concentration.

EFI 102- Understanding EFI Processes Through Detailed EFI Sub-system Analysis

By Christian Krahenbuhl

This is the second of four EFI articles from Cobb Tuning. This article will provide a more precise focus on modern EFI Systems; introducing you to various closed-loop control systems and explain how some of the basic calibration/tuning feedback systems are used. We will again introduce you to the new terminology and rhetoric used by tuners, engineers, & engine calibrators. This article will use more advanced animations and hands on exercises (with a spreadsheet) to educate you as to how calibration of modern EMS is done. We will breakdown the EMS into sub-systems; we will look at separately understanding and calibrating the Fuel System, the Ignition Advance System, the Boost Control System, the Camshaft Phasing System & Other Control Systems.

Ask Sarah- Does water injection work?

By Sarah Forst

Hey Sarah,

I have a turbocharged 1995 Integra GS-R with a T3/T4.  I usually set the boost around 8-10psi but sometimes I get up to 14psi.  I still have a stock ignition.  Is this boost too high for 91 octane?  One of my friends said I should install a water injection system, but doesn’t that just kill power?  Can you recommend any water injection systems?

P.F.

Suck Squish Bang Blow part 2- The Four Stroke Cycle

By Mike Kojima

Now that you know what all of the basic parts of an engine are and what they do, it’s time to understand how they work together in a system.  Almost all cars except for the rotary powered RX-8 and nearly all motorcycles use 4 stroke engines or what is called by engineers, the Otto Cycle to turn the chemical energy of gasoline into power.  Manipulation of the 4 stroke cycle is essential for obtaining more power from a motor so it is important to know what the different parts of the cycle are and how they affect your power output.

 Project Pathfinder Part 10, How to Build the Nissan VG30E

By Mari Umekubo

We are getting quite excited as Project Pathfinders motor is now up and running. We are out to show that a solid and reliable naturally aspirated Nissan VG30E can be just as strong or stronger in the power department as the VG33R supercharged motor in the  Frontiers with vastly superior fuel economy.  We also want to show that we can get the pulling power of a small V8 out of the VG. Last month we covered some tricks that Dan Paramore of DPR used to make our heads flow.  This month we will dive into the shortblock of our super Pathfinder.

AEM's Plug and Play ECU for the Chevy LS1, a Swappers Delight!

By Mike Kojima

Being able to have full control of engine management is a huge advantage when putting together one of the new generation hybrids.  We found a great remarkably simple solution for tuning with AEM's plug and play EMS for the LS1. The LS is fast becoming the new hybrid swap replacing K motors in Nissan S chassis and finding homes in the engine bays of 1st and 2nd generation RX-7's.
