Can the Yaris handle 6psi with stock ECU, injectors and fuel pump?

If the Yaris can handle the 6psi of boost, i will be able to build the cheapest and simplest supercharger kit on the market today and be able to sell it to anyone who wants one. if it's just a matter of upgrading the fuel pump and using some slightly bigger injectors and letting the ECU do the rest. then i think i could really pull this off. the kit would comprise of a supercharger(duh!), an intake pipe from the supercharger to the throttle body, a BOV on the intake pipe and maybe bigger injectors and fuel pump(depending on the Yaris responds to 6psi stock). so, please let me know what you guys think.

From what I've read on the Forced Induction forum; the stock fuel pump will definitely work and stock injectors should work as well. But I am by no means any sort of expert on the subject.

But I would be interested, depending on price, if it works. =)

+1 stock pump/injectors should handle 6 psi. Just need a piggyback for the ECU.

Blitz supercharger blows 7 psi with stock injectors and fuel system. I ran an 8psi turbo set up with Scion tC injectors and stock fuel system otherwise.

Garm can answer that best, I believe he ran his car prior to this with 8psi on stock electronics with just bigger injectors.. Gave a couple CELs of course, but with lower boost you *may* be able to get away with it

I was planning to build a turbo kit but I don't want to bother with a piggyback management for now so I was planning to run a low boost for a while just to get the kit started.

Ughhhh since no one asked this yet.... What model supercharger, how do you plan on using a BOV and why would you need one? You're leaving alot to imagination and I hope you can provide some solid good answers! :)

I've been planning on making a turbo kit for a while, but it's been all talk and research research research until I'm starting to pull a few strings and get things together with my business.

Honestly, I still think the Power Enterprise Supercharger kit is still the best one I've seen so far. far better than the blitz. This is only from videos I've seen from japan.

i don't see how a centrifugal supercharger is "better" than a positive displacement SC.. but to each their own.

I'd like to tell you what model supercharger, but I won't. All I can tell you about the supercharger I have in mind, it's a maintenance-free unit. No oil required. The BOV will be located on the one and only piping that goes from the supercharger to the throttle body. I would use a BOV to prevent any boost from putting a strain on the impeller and for those who love the sound. I'm looking to run as much boost as possible with as little mods as possible.

call me ignorant, but i've never heard a SC using a bov, wouldn't that defeat the purpose of the SC?

superchargers generally use bypass valves or butterfly valves. i wouldn't a BOV on a stock ecu'd car, especially if the bov is located between the MAF and throttlebody. you aren't delivering metered air to the engine, it's being vented to atmosphere.
