Turbo Information

Articles and how-to's for forced induction vehicles.
Forced Induction: Turbocharging The purpose of this thread is to give a basic walk through of turbocharging a Honda. It is neither a guide, nor an exact build list. It was designed merely to get new people pointed in the right direction of making some power. First, we'll start off with some basic knowledge. These are things you should know and understand (in my opinion) before attempting to turbo your car. Understand what a turbocharger is, and how it works. (How do turbochargers work? |...
How much Boost can a Stock (OEM) Honda MAP (Manifold Absolute Pressure) Sensor Read? On a stock map sensor, the amount of boost you can run is limited due to the fact that it doesn't know what to do with values out of it's voltage range and the result is the ECU throwing a code and putting your car into limp mode. The OEM Honda MAP sensors are roughly ~1.7 bar sensors (details below) 1 bar is 1 atmosphere of pressure, or roughly 14.7 psi. There is natural variance in these values based on...
How to Read a Turbo Compressor Map By JustinSane A compressor map can be a daunting thing to look at, but I will show you a few simple tricks to use a turbos compressor map to learn a couple important pieces of information. In this tutorial I will use the TD05 big 16g currently on my CRX as an example. You can download the map below and print it out to make it easier to follow the tutorial. Determine how much Flywheel Horsepower a Turbo can Support A few facts that your should take...
Mitsubishi made this document to explain how a turbo works and how to diagnose problems. pdf document is attached.
Turbocharger Trim Sizing A/R Explanation A/R is the rated volumetric efficiency of a turbos 2 sections, so to speak. Imagine if you have a garden hose spraying water out at a pinwheel with the hose open ended, the pinwheel spins okay. Put a nozzle on it an the pinwheel will spin like mad. There are issues with the nozzle on the end, you lose volume but gain pressure. With the nozzle off you gain volume, but lose pressure and you can't turn the pinwheel as much. Simply put, on small...
One of the questions that seems to come up quite often on this site is about what is needed if you decide to piece together your own turbo kit. This is easy to do in your own garage if you have a means to cut pipie and a welder. If you have the technical know-how to put a flywheel into your car you can put together a turbo kit using resources on the internet. Most people start by searching eBay and find a kit similar to this these usually run for between $700 and $3000 dollars...
Original thread from: www.preludepower.com I wrote this thread to help out all those who want to goBoostedorTunetheir 3rd Gen Ludes. I noticed a lot of new people are starting to ask about Boosting right off the start, so I took it upon myself to help out all theNooBiesand try to cut down on the massive overposting of others saying"Search!!!!". I hope this points you in the right direction. I make no warranty's nor guarantee's, this is a collection of information I collected from the...
This is going to be a multi-part series that will be written over the course of a couple days. It will overview of building a complete EFI system for your turbo Honda and taking it all the way from parts in a box to a high-power, running correctly machine. A basic outline of this thread is:What Parts are required/already a part of the EFI system Getting it all together Getting it to run correctly Making power
Static and Effective Compression A debate that often is pondered by not only Honda enthusiasts but all performance enthusiasts is whether one wants to go the N/A route, or boost with a turbo or supercharger. While each has their own benefits and cons list, debating this is out of the scope of this article. This article is about how boost adds power, beyond the saying "it adds more air to burn". We all know that motors use compression to make power. For example, a B16A makes 10.2:1 or 10.4:1...
Detonation By: Dennis Adams Detonation Detonation or "knocking" arises from the production of an explosion wave in the combustion chamber. This is due to rapid ignition and combustion. A portion of the unburnt air/fuel mixture becomes compressed prematurely, which in turn rapidly increases in temperature until it ignites uncontrollably and almost instantaneously. The shock wave produced has a characteristic of a metallic sound and can vary in magnitude. It can range from a mild form...
EGT, or Exhaust gas temp. gauge is a very important tool to have on a boosted car. putting it in different places can alter the readings. the best place to put it is about 2 inches away from the head on the 3rd runner of the manifold. Why? #3 is ALWAYS the hottest cylinder. 1+4 are more surrounded by water than 2+3 are, an because of firing order, 3 is hotter than 2.
Factory Turbo Cars This is a list of cars that were developed by the manufacturer to be turbocharged. It is common for a 'junkyard' turbo setup to obtain a small factory turbocharger and use it with a small boost set up on D-series builds instead of a swap and other lower power applications. This list is not exhaustive and many newer vehicles are not included at this time, such as the WRX, EVO, Genesis, BMW N54, and many other OEM-boosted applications. Vehicle Make Model Year Engine...
To help us all help you with this question, we need to know what motor and what mods are done or planned to do for your motor. Then we need to know what turbo you are running or plan on running. Every turbo puts out a different amount of CFM's at the same psi. In addition, a car which has better flow in general (i/e head port/polish, high flow manifold, throttle body, free exhaust, etc), and more compression will make more power on less psi as well.
