Question:
could u add supercharger or turbo charger to crate engines to increase there horsepower to an even higher level?
Answers:
Power adders can be used on a crate engines but all engines have their limits. Some engines are built more specifically to handle power adders like turbos and superchargers. Most engines take to a turbo easier than a supercharger. Again, all engines have a maximum amount af power they can handle before they tear themselves apart.
Is there info on the internet regarding curb weights & gross vehicle weights of passenger cars?
You bet cha - you will add a lot of horsepower, about 50% more. A supercharger will take a 200 horsepower engine up to 300 horsepower, no problem. Here's why - Half of the horsepower your stock engine produces is used to suck air into the cylinders. When the piston goes down before the power stroke, it pulls air in along with the fuel, unless the car is fuel injected. Some manufacturers try to help the engine with "Ram" air to try and ram air into the engine, but it's a very small improvement. A supercharger will 'blow' air into the cylinders, for street use, at about 8 psi. Hence the name Blower for a supercharger. That frees up the horsepower used to pull air into the motor. The energy it takes to turn the supercharger is minimal compared to the horsepower gain. A supercharger is driven by the crankshaft, so as soon as you step on the pedal, you are blowing air into the motor. A turbocharger is driven by exhause gas. So there is a lag in horsepower gain. It takes time for the engine to produce enough exhaust gas to drive the turbo. So, they are rated to work at a certain RPM. This is called 'reeling up'. A supercharger doesn't reel up - it's instantaneous. There are a few other things you can do to gain more horsepower with a blower or turbo. You can add a high lift/short duration intake and exhaust camshaft. Also, you can reduce the compression ratio. This can be done by increasing the head gasket thickness (you can buy a thicker gasket for some cars, they make them just for this reason). I've seen some guys just put 2 head gaskets in. You can buy a custom made gasket for this too. They are usually made out of copper. You can also have the combustion chamber head made larger by a machine shop. What I did for my car is I ordered aluminum pistons that were shaved off. I went from 10.5 to 1 ratio to about 9 to 1 ratio. I now wish I would have gone even lower. A lower compression ratio allows the blower to force air into the cylinder easier. It also makes the engine more reliable as far as starting it goes.I also added a high flow air intake and exhaust, along with some electrical upgrades.
Why do the wheels on a stagecoach sometimes appear to be going backwards when traveling forwards?
Yes you could. I wouldn't if it was my engine, I would go with some big valve ported and polished heads. either a six pack or dual 4 barrels on a high rise aluminum intake. Get a strong cam. like 290 lift, 490 duration... for a small block. forged aluminum pistons with at least 11:1 compression.More Questions & Answers ...
