Hi Everyone,

Still new to the supercharger engine and constantly updating things with all your help and advice. 

Are there any visible signs to show when a supercharger is not working?

Am i right in thinking the engine would not run if the charger was not working? 

My charger does not whistle like many people have described and acceleration is on par with a standard SPI i would imagine it to better, or have i got my head in the clouds again

Cheers

Peter

What do you mean when you say 'not working'?

Are you sure you have one?

I've heard people point to the alternator and see the belt attached and ask if it's the supercharger,


Just wondering haha

Suck through superchargers don't make much "whine" if the engine is running and you have a supercharger, the supercharger will be running as it's a pulley system off the crankshaft pulley.

Coopdog, just taken a second look just to be sure, yep charger is right there next to the rad right?  see photo.

 

Think i need to get it back on a rolling road, something is just not right. A standard SPI pulls away at the same pace.

Looks like a good installation, maybe get the fuelling checked out as it should be quicker than a stock spi

If you feel the car is underpowered, you should get it on a rolling road to try and diagnose the fault. They will be able to set up timing, fuelling etc. and check your car for any other faults such as low compression or worn out SC.

 

Does the SC make any noise at all? It definitely should whine.

Mine didn't wine much at all, about the same as a gearbox whine. I think its down to the fuel dulling the sound down.

 

Looks like a nice set up with the water heated manifold.

Thanks guys, I think a rolling road set up is required. My engine seems to breath a lot ofoil  vapour. I made up a catch tank and added an extra breather to the old fuel pump housing to stop it going all over the engine.  Could this be worn piston rings? the engine does not over heat or smoke.

For those interested the water jacket pipe works a treat and solves the problem of the carb icing up. I used to tap the ice off with a hammer before ! Now i can control the amount of warm water going through it using the heater cable. 

 

There is no real noise from the supercharger, i can hear the carb sucking and the exhaust mainly.

Best way to find out mate is to do a compression test and a wet compression test to find out.
