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.

sorry to thread jack but just a quick question. Can the yaris ecu handle a 5-6 psi with no piggyback?

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.

Speaking of which didn't someone on here get that kit? i think it was frownonfun or something like that.

yeah and then never updated anyone or anything and then Power Enterprise Evan went off the face of this earth... sounds like something shady went down to me!!! Hope someone knows if the guy(s) are okay
frownonfun got it finally, hes been working on translating the instructions from Japanese to English last I heard.

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

I don't see why you would need to translate instructions from Japanese to English if its just like 10 parts... couple pipes, bracket, supercharger, what else?

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.

Each have their pros and cons... a centrifugal supercharger is more efficient in terms of power delivery. It sits somewhere in between a supercharger and a turbocharger when looking at efficiency. They have a tendency not to run as hot as a positive displacement SC. They are well suited for our cars since we have light small cars that rev high. Usually they are completely self contained so no need to run oil lines to the supercharger which makes installation easy. It really comes down to what kind of motor you are running and what you are going to do with the car. On a low revving large displacement motor a positive displacement SC would better...
I would love to see a comparison with dyno results with the blitz verus the rortex both running at the same psi. I have a feeling the centrifugal supercharger will produce more hp but the blitz will delivery more bottom end power. And bottom end power is what these little motors need.

Ok, you're really going about this all wrong first of all... Most SC nowadays are little to no maintenance at all. You won't be overboosting or putting strain on the unit with 6psi, and just to do it for people who love the sound is just ludicrous.
If you're buying a SC you obviously bought it for power, the sound you can make with a ghetto tail pipe whistle kit. And saying you're going to run as much boost as possible with little mods is an extreme understatement. Can you atleast provide a map for us to look at the flow rating of it?
I'm not trying to harsh on your thread or be a dick but its reality...If you don't want to post what supercharger it is, people will find out when you post a picture assuming you are going to test it first. and if not, we're just going to have to get a mystery supercharger i guess. But if its CDM, its CDM, not all of it is bad stuff.
If you can accomplish this then congrats on a job well done, but i think you need to take a step back and re-approach this and do more research on induction
