ok nester and evryone else who contributed to the answer . but I would like to add one thing , a centrifigul blower vs turbo at the same psi isnt even close . peeps r running 200whp with the blower and atleast 230 with the turbo . thats 30whp difference . not to mention the blower is at a 1 to 1 boost ration where the turbo is making its power by 2500-3k rpm .

 

This doesnt prove anything, i know personally that a ZPI stage 0 will beat a trd supercharged tc. I didnt see u at the shootout, so why are trying to prove somthing false. If u think u can beat a stage 0, prove it next shootout. don't prove it with some neighborhood street race result.

 

The biggest difference is that the supercharger makes its peak power much later in the power band. The turbo gives you the mid range power and torque that we all love. To say which would win in a race is hard to do. Driver plays the most important role in that. I am confident that a S/C car and a turbo car with the same peak power that the turbo will win all day long with comparable drivers.

I am sure Simply Scion out drove our stage 0 car more than anything to do with power. Both options will make you love the tC more than you ever thought you could. In my opinion the turbo is more for the hands on enthusiast and the blower is for the guy who wants a faster car. This is not to say that both are not owned by each type but more for what they are designed towards.

who are you again?? I see someone got a blower and is getting all happy cause hes making internet friends!! Please dont let it get to your head I do respect your xA, being that I turbo'd my xB a long time ago(been sold since October)...welcome to the party though

 

Not meaning to interrupt with the afr numbers but since it's already happened...lol. We should see some good races between my s/c tc and the turbo'd cars at the next shootout. I'm planning on going up to ZPI at least a few times this summer and meet the guys and have them put some stuff on for me if I get some money coming in. As you can see from my signature I can say nothing but good for ZPI and I respect both forms of f/i and if I was getting ready to buy a new form of f/i I'd probably honestly go with a turbo but since I have the s/c and have so much money in it I'm going to stick with it.

 

I am not a f/i expert. But seeing as to how trd can run without any real fuel managment (that reflash doesnt really seem to do much exept decrease the power) I dont see why a stage 0 cant. As for the intercooler I believe zpi already proved that at 6 psi an intercooler is not a necessity above it yes help a little yes but not a nesecitty.

I think we just got lucky with the ecu that why there is no real need for a managment at low boost levels. Everyone got used to hondas and always needing fm to run any boost at all. If trd acomplishes it then I think zpi can do the same with a turbo.

 

you do realize that the reflash isnt all about A/F ratios right?? What about timing? Its obvious running the car without the reflash destroys the piston rings over time...why should a stage 0 be any different? The ECU will pull back timing once it senses detonation, but it can only handle so much.

 

The reflash decreases timing which in turn is why it decreases power. Now you think for a second and tell my why TRD, in all their years of experience, and infinate resources would do such a thing?

Exactly, TRD is NOT doing it on a stock ecu, and they are NOT doing it on the stock injectors. I'm not saying that it wont work because its been proven that the car will run on the stock ecu, but smoking Camel lights isn't a "better way of smoking".

Not to mention, that its VERY difficult, especially difficult in this case(due to many factors), to compare these two FI applications. They are COMPLETELY different in most every aspect. Velocity, IAT, Effciency, back pressure, parasitic drag, ect ect ect. None of its the same.
