ok me and dmitry are having a debate

say i have a supercharger with a clutch on it powered by electricity
now i have it tuned with a smt6 and i have 440 injectors on it and a 10:1 fmu and a intercooler
now i turn off the clutch sending no boost to the car do you think it would turn on?

i say no it wont turn on cuz the ecu doesnt recognize the 440 injectors since the smt tricks it plus the fact that with the intercooler and no boost to push the air through the pipes the car would struggle for air

d thinks yes cuz the maf would adjust it for air

who is right?

 

wtf are you talking about? electric superchager and turning the clutch off??? Are you on crack?

 

Seriously, wtf??


I'm gonna forget about the other crap you said, ..........but the maf and ECU won't subtract enough fuel for 440's without a piggyback cutting the maf signal.

 

i think hes talking about an electric supercharger that gains power from a clutch on say, one of the belts. the electricity built by the generator would be used by a motor to build pressure. just like the alternator, except it has a motor too.

i guess. dont have an answer to your question though.

 

wait a supercharger powered but an electricty generating clutch, wtf?

 

If your tuning the SMT to run your car with 440cc injectors it will still run the car without any boost since the car only makes boost under a load so the car should be tuned for both on boost and off boost conditions so the SMT will not be a problem. As far as the supercharger goes it has been done in the past where people would use the clutch off of an ac compressor to turn the supercharger on and off but the setup will depand on the supercharger used, most will allow enough air to flow through while cruising down the highway at 65mph but if you go wide open throttle without boost it will be sluggish as the non-running supercharger will restrict the airflow but the ones I have seen used a bypass valve to bypass some air around the supercharger when the clutch was turned off, so the idea will work as long as it's done the right way.

For you guys above^^^ hes talking about using a regular supercharger like the alpine kit but but putting a a/c compressor type clutch on the pulley that makes it spin so when you going down the highway just criusing you can turn the supercharger off this way you will get better gas milage since the motor does not have to spin the supercharger and the life of the supercharger is extended since it's not spinning when it's not needed, like I said I have seen it done on several mustangs using centrifical superchrgers and most guys would do just to increase the lifespan of the supercharger and as long as the right setup is used it can be done.

 

so i guess were both right in a way
i figured it would shake and start to stall since air isnt being routed quickly enough to hold the motor over at crusing speeds

maybe i can route the s/c to like a tps switch from a nitrous kit or even a rpm window switch that way the clutch doesnt engage until a certain rpm hmmm interesting it would be kind of fuel effienent at lower in town speeds then like i can turn it on at a certain rpm hmmmm got my mind goin lol

 

just wire clutch to a button that will engage clutch and make s/c bypass, this way you'll have 2 engines under the hood (n/a and boosted) fing02.gif .

Sometimes you may need power (boost) from low RPM.

 

yeah thats true

with a window switch i might as well just get a turbo

s/c rocks at low rpms

lol there is so many things you can do to this heck you can wire up a progressive nitrous controller to it that way if your running high boost like 11 psi or so you can have it setup to leave at 5psi then gain up until 11 so you can have traction out of the hole

anyone have pics of said bypass?

 

^^^
I know VW Corrado G60 has a s/c with bypass line, but it's a bit different - when you close throttle bypass valve opens (progressivle depending on throttle position) and air go back to S/C (s/c has 2 inlets and 1 outlet).

So you can hook up that valve so it will work like S/C bypass.
