cooler denser air



cooler denser air

Im always rather amazed at the guys that don,t stop and think about the total process of making power and the failure of so many guys to think thru how each step can be improved.
it really doesn,t matter if you have a single carb, dual quads or efi, cooler denser air will result in a more efficient engine , simply because cooler denser air contains more oxygen per cubic foot of air entering the engine, thus allowing more fuel to be burnt resulting in more power potentially produced, and isolating the engine air temp entering the engine your mixing with fuel, from the under hood temps goes a long way to help efficiency

yes it will in most cases take some time, fabrication skills , the ability to measure and think things thru, but the results from some individual creativity and custom fabrication can be amazing, and easily worth extra horse power, with some careful measuring and thought a cool ram air custom fabricated filter air filter housing and isolated air ducting from outside cool air could be designed and built for for most cars
like almost every other potential change you might make theres ways to duct cool outside airflow into the engine compartment to the carb or efi to limit the engine heat it absorbs in transit, cooler air is denser air and it contains a higher volume of oxygen, and its oxygen thats used to release the potential power in fuel, now you can get creative and add a super charger, turbo or add oxygen by using NITROUS, but all those routes will cost you money you might not be able to easily afford, but there are rather simple things you can do to route cooler outside air into your engine rather than allow the engine to suck up higher temp thinner and potentially far less usable air from under your hood.
you can start by getting a good air temp. gauge and measuring the air temps under your cars hood and then measuring the outside air temps. and don,t be surprised at a 80F-120F temp difference after your cars been running for awhile, between the two areas that can potentially be used as a source of air to mix with your fuel.
you might want to get creative and design a custom built hood scoop, vents or air ducts to route cooler outside air into your muscle car or corvettes engine!

now heres a series of pictures a guy took when he designed a cold air routing duct and hood scoop to route cool air into his carb, from a scoop on the hood, he tested the results and had an 80F-100F difference in intake air temps due to the custom air ducting and insulation layer under the corvette hood, an 80F-100F temp difference will produce an easily measurable gain in power

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!
