What is 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.
Can you cam a supercharged engine?
Installing a camshaft designed specifically for a supercharged engine is best. But often the existing camshaft works surprisingly well, and those with lobe separation angles of between 112 to 116 degrees are ideal. Of course, when cruising and thus not building boost, nothing more than a normal camshaft is required.
What is a boost cam?
See all 30 photos Cam selection in a boosted application means filling the cylinder with as much air and fuel as possible under pressure. Pressure comes immediately with a supercharger.
What is overlap in camshaft?
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.
Can you run a supercharger cam without a supercharger?
There is nothing wrong with running a blower cam without a blower. If you can’t do both but want to do one now then just pick which you want most.
Whats cheaper Procharger or supercharger?
Procharger is the brand name of a centrifugal supercharger that works differently than a basic supercharger and delivers a consistent stream of air to your vehicle. But they can be more expensive than the basic superchargers and also have a distinctive rotary whine that can be heard over and above a revving engine.
Can you cam and turbo an engine?
The art of turbo cam development is to properly size the overlap to allow the inlet charge to start moving early for best cylinder filling while not allowing too much of the air and fuel to go out the exhaust.
How do I stop my exhaust reversion?
How do you prevent it?
- Improve Your Exhaust Flow: A stock exhaust can have 8 psi (or more) of backpressure at 6,000 rpm.
- Pick the Right Parts: Long Duration cams with lots of Overlap make more power at high rpm.
- Warning: DO NOT port match the cylinder head to the headers.
What happens during valve overlap?
Valve overlap occurs when the piston nears TDC between the exhaust event and the intake event. At higher speeds, the extra amount of intake charge brought into the combustion chamber provides a substantial increase in available power. The amount of time that both valves are open in directly related to engine rpm.

Which is the best Street Cam for a supercharger?
Almost every source says it is important not to use a “hot” street cam, but then some spec out a 230/240 duration at 110 or 112 LSA cam for supercharger (Comp Cams, BDS, etc). My experience has been that low end suffers with this much duration, even with a wider LSA.
