Thats why exhaust drive (Turbo) or belt drive (supercharger) make so much better sense as they manually go with RPM and then all you have to do is get the fuel air mixture right which could end up costing thousands scince no one makes an aftermarket kit for the NA as far as I know. If your trying to do both electrically then I suggest an engineering degree and a lot of research before attempting it.
It sounds as if your trying to compensate by putting in bigger injectors and hoping the stock ECU will still work, but what happens when your not under boost and the bigger injectors make it too rich? |

Ive heard you can use some of the aftermarket piggyback fuel computers with the stock NA, But it will still run too rich off boost. But nost as much as just stuffing the bigger injectors in.

ovbiously this is a bigger project than i thought, wow, but can u guys imagine the possiblities of this think, an electric turbocharger? no waiting for spool up time, you dont hav to b at a high rev to use the full potential of a turbo, the boost can even be speed variable,
if only i had the money to develop this

There is not much lag if your turbo is set up right..I have 13psi of boost at 2200 rpm on an upgraded CT-26 all the way to redline.
Some guys run a small turbo for low RPM and a larger turbo for the higher RPM.. I am back to wanting to use a small supercharger to spool a larger turbo for no lag and off idle boost.. Best of both worlds without the turbo slowing the exhaust flow through the head... Or use them both together. Small supercharger and a big turbo.. Thats just my idea...

Jet engines work kind of like that. They have a small electric or really small jet motor that spools up the larger motors so they can start. It wouldnt be hard to do that with a turbo. Youd actually pre pressurize the exhaust, And if thats what you were thinking of doing, Kudos. You would need a one way flapper valve kinda thing. Not hard to make. So exhaust gas doesnt come out when the pressure builds. Plus the motor would have to make more CFMs and pressure than the motor running at idle. You might be able to use parts off of a 2jz gte or a twin turbo rx7, cause they have valving like that for the sequential turbos.

And now im thinking, you could even use a wastegate. Like a factory one, if you can seperate it from the turbo. Junkyard item. Plus there designed to hold back the heat and pressure.
