How much power does a 144 blower add?
04 The key player in this kit is the Weiand 144 roots-style supercharger. It’s advertised to give a 25-40 percent boost in power. The reason for the large range of performance gain is that it’s very dependent on what engine it’s bolted to.
Can you put a blower on a 383 stroker?
While they can be made to work on more complex EFI machines, about 99 percent of the time these little blowers are installed with a carb sitting on top of them. Since there are plenty of them out there, we chose to put one on top of our 383 stroker.
How much horsepower would a blower add?
Usually with a mild blower cam and a larger carburetor you can expect a typical small block to produce anywhere from 360 to 400 streetable horsepower. The addition of a set of good heads can boost this into the 440 to 470 hp range. Torque on an engine of this type typically will be in the 400 to 440 Ib.
Do superchargers increase compression?
If we now add a supercharger even with just a small amount of boost (let’s say 7 psi), this is roughly equivalent to raising the static compression ratio to 14:1 at full boost. Having said that, this is the effective compression ratio at that amount of boost.
How well does the Weiand 177 mini blower work?
The system worked flawlessly, but it bled off about 5% horsepower to run it. The Weiand 177 mini-blower kits are made to run with a stamped steel crank pulley sandwiched between the dampener and blower pulley. So the locating pilot of the Weiand pulley is smaller than the dampener hole.
