hey guys, just wondering about the greddy emanage piggy back. wondering what gains one can recieve when tuned. i am thinkin abnout purchasing one along with a smaller pulley, has anyone done this yet?

thanks guys

I believe revitup tryed to use an Apex S-AFC.... said the car did not like it and not to waste your money

It works and can control fuel and timing under all operating conditions.
Performance gains are limited to your ability to get it tuned on a dyno.
I would go toward the E-manage Ultimate, but either will work.

Needless to say it takes the correct wiring to make it work and I haven't had the time to write an install yet. There are some limits to how well it operates things, but only because of how the PCM controls the Throttle body and boost bypass solenoid. Also the MAF isn’t being interfaced at all because the E-manage doesn’t yet have a known map for the freq range of the MAF, but at long as it’s within about 10% of the expected MAP value seen by the PCM no codes are set. As long as you don’t try to exceed the limit of the MAP or MAF range then it’s not a problem.

Nothing against Rev for trying the Apexi, but I'm not 100% convinced it wont work also. I think they just focused on MAF manipulation and not MAP (where the load is really measured). It's OK there are only 3 different pressure gauges on the engine used by the PCM for fuel and delivery control.. technically 4, but the fuel tank pressure it less involved.

thanks for the info man, i have a greddy e-manage sitting around and would love a wright up if you ever find time.

this has nothing to do with what your talking about.. but whats with the bov in your 1st s/c kit?.. i was under the impression that a bov wouldnt funtcion on a s/c engine

If I am not mistaken BOV in this case is just laymen's for the bypass valve that you guys have. So their kit upgrades your bypass valve, not add a Blow-Off Valve. I might be wrong. :)

thanks for the input guys

I have been building superchargers for Saturn S series for 5 years now, but it's unrelated to the bypass valve on the RL/SS.
The SCdyne S/C system uses a centrifugal supercharger (like a turbo) where the RL/SS uses a positive displacement supercharger.

In a system like that positive pressure can build up between the blower and throttle body causing problems for the blower. To keep that from happening a blow off valve is used to release pressure from the system when the throttle body closes.

In the RL/SS the bypass valve opens up when you are at part throttle and recirculates the air in manifold preventing it from generating any pressure. This lowers the work the blower is doing when you don't need it.
