New supercharger by-pass mod ...

[jmc007]

I think I found the easiest and most efficient way to do it (Maybe you will say that it seems to be the same mod they do on the following site http://www.saturnionredline.com/boostmod.htm but it will not produce the same effect !!!) The way they've done it on this site caused the bypass valve to be always closed; the actuator's lower nipple is closed, so the "before blower vaccum" is not able to make the actuator (by-pass valve) opened. It results in a by-pass valve that is always closed and that is not good for fuel economy and efficiency.

So here it is: Unplug the end of the hose that is located on the lower nipple of the bypass actuator (this is located on the side of the supercharger), and plug the end of the hose with a screw (Don't plug the nipple !!). Period. (Yes this is the hose between the selenoid and the by-pass valve. IMPORTANT you must disconnect it on the blower side, not on the selenoid side. Then plug the hose, not the valve's nipple ! Leave the valve's bottom nipple to the air.)

The following result is that you will be running no boost at idle and the same low boost when cruising (all like stock), but you will be sure that in any ways at WOT you will get the max boost from your supercharger, if the allen screw on the by-pass actuator is set in a way that the valve is 100% closed).

What do you think ?

I'm not going to be the first to test it but it sounds like if you do that your car is going to hate you.

i have this done boost kicks in as soon as u step on the peddle. no light .

Full Boost?

something doesn't sound right??? just my opinion...but if it works and doesn't hurt or set off codes then great

I've done it this morning; it runs well.

But for those (like me) who are already running full boost (12 or 12,5 PSI) at WOT, it will not profuce more boost.

But it will ensure that the PCM couldn't vent some boost under the specified abusing conditions.

Have a nice day !

I assume the gas mileage should plummet as well...

yep no bypass = bad gas mileage. People really worry about this more than they should. Next time I goto the dyno I will do a without bypass and with.

[riz906]

its just faster boost thats it ....i dont know about gas milage ? i like it
