NOTE: It is important to understand that for all practical purposes, an engine does not know what size supercharger is bolted to it. YES! Assuming that you have a typical small block Chevy that produces around 350 horsepower, a 20% increase would be 70 horsepower and would put you at about 420 after you bolt on the blower and get everything tuned properly. The peak numbers shot up 128 lb-ft for torque and 126 for horsepower. Do existing problems from an American car carry over to its rebadged clone  sold overseas? Although some manufacturers claim a specific horsepower increase, superchargers actually add horsepower as a percentage gain (percentage of an atmosphere). I had a new battery with the following info on the test? Stepping up to a 7.0-inch crank pulley resulted in a jump to 452 hp and 492 lb-ft of torque. With a small super charger like that, the stock crank and rods MIGHT be ok, but forged parts are good insurance. blowers are engineered to give a 20-40% increase in horsepower. So, on average, a supercharger adds a horsepower boost of about 46 percent of the engine's original specs. Get your answers by asking now. everything to do with Hot Rod, Customs, Low Riders, Rat Rods, and more. Floor the throttle at sea level and the gauge will read 14.7 psi and 12.2 psi in Denver (with “0” inlet restriction). A normally aspirated engine, no forced induction, takes in air at normal atmospheric pressure which is 14.7 psi at sea level. In other words, this is the amount (volume) of air being pushed through the end of the leaf blower. Still have questions? Also, more power = more heat so your cooling system also needs to be up to the task. The premier site for A blower is not a simple bolt on project. If you are set on the 30 then go with a 47 blower and run it at the 3600rpms. The following is a generic equation to determine the required horsepower to drive the fan or blower element . blowers are engineered to give a 20-40% increase in horsepower. The Summit Racing and Weiand sites both say that the 144 c.i. I first bolted the blower to a 10.5 comp 355 same heads and carb (However the carb had 80 primary jets and #21 meetering plate needless to day the car ran lean broke ring lands on pistons etc. Join Yahoo Answers and get 100 points today. Estimate HP From Adding Boost : Wallace Racing BACK to Calculators Todays date is 12/7/2020 These equations are for recreation only. This is my first blower. This equation does not compensate for temperature, density or airflow charateristics of any particular fan or blower. Standard check valves usually have much stiffer springs and can be too hard for a blower to open correctly. In Blower Basics (Part 1), we debunked the myth that a supercharger is an exotic upgrade. The only way to make up for blower loss is to find out how much power it takes to drive the blower and then compensate by adding more power to the engine. Alcohol and E-85 can accept much tighter stripping since alcohol is a cooling fuel, and the tighter the stripping the more boost a blower can make. So, apply this figure. will a reg turbo 350 torque conv work with a 350C trans i don.t need lock up/. Equation: P = (Q x p)/(229 x ) or. In other words, we stuffed more air into the engine. Now, understand that 50 percent is a perfect-world scenario, and a supercharger does sap some efficiency from the car. But if all you're gonna do is the k&n and Borla catback, then I wouldn't tune it, just go with what you have an enjoy.
