I was talking with Jon from Goodspeed today (he used to work at Dynocomp) and he was talking about the possibility of fabbing a tube to recirculate the excess air that normally bleeds out under non-WOT driving, and having it blow back into the intake to create a sort of ram-air effect. It would also eliminate the "air leak" sound and also quiet the bypass valve down some when shifting (which that part I know I'd miss having)

It might improve engine response by having that additional air available in the intake the moment you start opening the throttlebody up and thus having more power available right off idle. It would be more something to improve non-WOT driving and wouldn't have any effect for WOT driving when the bypass valve fully shuts

anyway, I thought it was an interesting idea, but not completely sure if it would really be worth it or if there would be any bad effects long term that might come from it.

any thoughts?

 

one problem i see is that air being dumped overboard from the bypass valve is heated air due to it being before the FMIC. i know at part or light throttle operations the s/c is not working as hard/creating boost but it is still turning at a decent rpm blowing out heated air due to adiabatic affects. i think ultimately you will be introducing warm if hotter air back into the intake track of the s/c increasing the chances of detonation.

 

yeah I've thought about that but I'm not sure if actual detonation is going to be such an issue when just going part throttle.

in my case anyway I run water/meth injection so that should have no problem cooling the air for full throttle

I suppose that a larger intercooler might be beneficial for something like this where there's more volume of air circulating in a loop like this

I can monitor intake temps though with the Fcon

 

I did a feeler on this a while back and everyone was completely against it.

 

The 1st gen HKS kit uses a similar setup. The bypass recirculates back into the intake tube that feeds the supercharger behind the MAF. The only real reason to do it is because they use MAF. If you're using MAP, I can't see any real advantage.

Stock setup uses bypass right? Where does it vent to?

 

I doubt you would see any gains from this setup. Unless you really want to get rid of that whooshing sound at partial throttle. Otherwise, waste of time and money.
