Can you run a cam with a supercharger?

Can you run a cam with a supercharger?

When you go from naturally aspirated to supercharging, turbocharging, or nitrous you also have to go to a camshaft designed to work well with forced induction. Nitrous and supercharger cams generally employ very similar profiles because both do their best work at high rpm.

How much HP does a supercharger add to a 350 SBC?

How much HP does a supercharged 350 make?

Hennessey gives the GT350 a major upgrade to over 850 hp. Hennessey’s HPE850 package for the Ford Mustang Shelby GT350 adds a 3.0-liter supercharger to the pony car’s 5.2-liter V8 for a claimed output of 858 horsepower (640 kilowatts) and 673 pound-feet (913 Newton-meters) of torque.

What makes a good blower cam?

The basics of what you want in a nitrous (or supercharger) friendly cam is a wider lobe separation than what most “performance” or “race” cams have. Anything with a 112, 113 or 114 degree lobe separation is great for blowers and nitrous. It is also what causes cams to not “come in” until higher RPM’s.

What is camshaft overlap?

Overlap is when the intake and exhaust valves are open at the same time. It is expressed in degrees of crankshaft rotation. Not all camshafts have overlap. If they do, it happens at the end of the exhaust stroke and the beginning of the intake stroke.

What is a positive displacement cam?

The PD 224/238 positive displacement supercharger LS camshaft is designed for street performance applications in vehicles using 5.3-6.2 liter LS engines equipped with positive-displacement style superchargers. This camshaft can be used in a completely stock vehicle with just a valve spring and pushrod upgrade.

Can you just bolt on a supercharger?

Supercharging can be a straight bolt-on installation, and it works well with stock heads, cams and pistons. What’s more, it delivers better low speed throttle response and torque than a naturally aspirated engine with a big carburetor, big valves, high compression and “hot” cam.

What is lobe lift?

Lobe Lift is the amount (usually in inches) that the cam lobe increases in radius above the cam base circle. Tip: To quickly find maximum lobe lift, measure the base circle of the cam and subtract it from the thickness across the cam lobe’s highest point (see the diagram below).

What makes a camshaft lopey?

cams lope because of events, they open valves because of events, they do it at certain times because they are events. The smaller the lsa the larger the chance for overlap. If you have two cams, same everything, except for lsa, the one with the smaller lsa will have more overlap…

Can you switch a supercharger on and off?

1. The famous scene in the Mad Max film where he switches on the supercharger is commonly said to be unrealistic, but some cars have an electromagnetic supercharger clutch, which means it’s possible fit a switch that would enable you to turn them on and off.

Which is the best hydraulic camshaft for a 350 Chevy?

How much horsepower does a 383 supercharger have?

The 383 test mule was no slouch, even before the blower, with 10.0:1 compression, AFR 210 heads and a thumping ( .600 lift, 252/256, 108 LSA) cam. Run naturally aspirated, the 383 produced 550.2 horsepower and 491 lb-ft of torque.

Can a supercharger be used with a nitrous Cam?

According to the engine builders that we’ve interviewed, you can basically treat turbocharged, supercharged, and nitroused camshafts all the same way. Cam selection for these applications deals with taking into account the basic “funnel theory” of power-adder engine tuning.

How much horsepower do you need for a supercharger?

One downside to engine-driven superchargers is that each blower requires a significant crankshaft horsepower to drive. Even for a mild street engine, we’re talking about 35 to 50 hp required merely to drive a supercharger that may only then deliver an increase of 200 hp to the crank.
