Some of you may or may not know but in the past I worked for Titan Motorsports. During my 3 years there I had the chance to do some very fun things and this header test I organized was probably one of the most well received dyno tests during my tenure there. We had some great people involved and tested some very nice headers. Recently I found all the old dyno sheets on my computer and can show the results here. We originally had a thread posted on Honda-Tech with all the results but throughout the years the servers, images,...

Great information regarding the CP Pistons Ring Sets. These are all included with each CP Pistons order but unfortunately a lot of people seem to misplace them so we know have the information listed here for quick reference. This ring information can also be used for most popular aftermarket forged pistons.

When I find useful information on the internet I like to try and pass it on. Ever gotten irritated trying to figure out what your kg/mm spring rates are in lbs/in ? I came across this handy post on Evolutionm.net -- http://forums.evolutionm.net/evo-tires-wheels-brakes-suspension-sponsored-tire-rack/308025-spring-rate-conversions-kg-mm-lbs.html 1lb = 0.45359237kg 1in = 25.4mm .45359237 / 25.4 = .017857967322834645669291338582677 So now we know that 1lb/in = .017857967322834645669291338582677. So if we want a spring that's roughly 560lbs; we'd multiply both sides by 560, and come up with roughly a 10k spring rate. Alternatively if you already know the kg/mm rate and want to find out what the...

Crankshaft Vibration Dampers 101 BY J.C. BEATTIE OF ATI PERFORMANCE PRODUCTS Courtesy of ATI Performance Products - http://www.atiracing.com/products/dampers/101/index.htm I have been around dampers for a long time and traveled to different engine shops around the country to test actual crankshaft twist for the past 16 years. Throughout these years I have collected a lot of information that allows me to make informed decisions on “how much” damper certain engines need. When given the crank weight, peak normal operating RPM, horsepower, rotating system materials, rules about the damper specifications (if racing), and the application of the engine (road racing, oval or...

Courtesy of TurbobyGarrett.com ( http://turbobygarrett.com/turbobygarrett/compression_ratio_with_boost ) Before discussing compression ratio and boost, it is important to understand engine knock, also known as detonation. Knock is a dangerous condition caused by uncontrolled combustion of the air/fuel mixture. This abnormal combustion causes rapid spikes in cylinder pressure which can result in engine damage. Three primary factors that influence engine knock are: Knock resistance characteristics (knock limit) of the engine: Since every engine is vastly different when it comes to knock resistance, there is no single answer to "how much." Design features such as combustion chamber geometry, spark plug location, bore size and...
