I was just wondering what AFRs these cars are running with the stage zero and no aftermarket fuel managment ? I know on my tacoma trucks the stock FPR is boost referenced 1 to 1 when hooked to a vac/boost source . just wondering if these have the same setup ? thanks

 

Our cars are return less fuel systems. But as for AFR's I have not checked yet but I am pretty sure it is extremely rich (maybe even too much). I can say this because I had a crack in my exhaust manifold (I have a stage 0) and after driving for sometime I could smell gas in the engine compartment when I looked under the hood. I will soon be getting a wideband to verify these things but maybe someone else can shed some light on this.

 

somebody , anybody I know you guys have used a wideband !!

 

most people that are going out and buying a turbo kit without any sort of management whatsoever, will probly overlook having a wideband. IMO, majority of the people that would buy a stage 0 kit, are just in it to say they have a turbo, then you have the people that buy a stage 0 and slowly build it up cause they cant afford the stage 1 kit.

 

4 grand is a lot, is there anything cheaper/reliable?

 

10.2:1-10.5:1 under boost all the way through the power band with a Stage 0.

Rich, Pig Rich. Pefect for the person who hammers like it's their job.

 

There is a such thing as too rich though. Not talking ish at all. Just dropping some info. If you run TOO rich consistently you stand the chance of fuel washing the cylinders (cleaning away the oil residue) and toasting your rings...

 

I'm aware of this. 10.5:1 under boost is not going to hurt anything. The car cruises very conservatively.

Mind you, this is how the car reacts to boost. We do not run engine management on the stage 0. It adds this much fuel because the factory ecu is smart.

The TRD supercharged cars do the same thing, with or without the reflash.

 

Like I said not talking ish at all. I'm also not saying that AFR is going to do that. Just wanted to make sure people knew that there is a such thing as TOO rich..

 

This is why the TRD Super Charger is a good deal. Someone else installs it, Someone else did the engineering on it. Someone else sized the injectors, remapped the fuel curve. Changed the shift points in the tranny. Someone else determined the new setting on the engine thermostat. Someone else determined the new temperature at which to cycle the cooling fan and on top of that they added some extra safety margin for the lead-footed drivers.

The trd sc is bascially a stage-1 package. When compared to other stage 1 packages it actually is not a bad deal. The problem is that you don't get the high hp numbers that the turbos get.

If you go turbo you will at some point end up doing a great deal of this yourself or pay for someone else to do it for you. Lots of hard work that many are not ready to tackle.

What that saying -Got to pay to play...

I don't think that the Stage 0 is for real. It's just a transitional point to Stage 1 which is what you realy need for a dependable install.

 

The TRD S/C compares to our Stage 1? At what level? Our stage 0 kit will smoke a TRD S/C all day long... The Stage 1 car vs a TRD S/C isn't even a race.. It's just a straight slaughter.

As for the stage 0 being real, ask all our stage 0 customers how real the power is.

 

This was all a joke right? Please tell me you werent serious.

Yeah I am not boosted by ZPI, but if you wanna sit here and bash their products I think you better keep browsing the forums about their Stage 0 and Stage 1 before the true die hard ZPI supporters come after you.

Hell, even go watch some of their videos.

ZPI Stage 0 & 1 > TRD S/C....Deal With It

Worst post I have ever seen trying to compare a S/C to ZPI's F/I.

 

please dont misinform people....a stage 0 will only run as well as it can with supporting mods. A stage 0 intercooled with no management will lose time and time again against a TRD s/c with a pulley...any pulley, wether its a ZPI pulley, or a NonStopTuning pulley. I think we proved this already...not trying to reopen a can of worms, but it is what it is.

 

Where is it proved that an SC tC with a pulley is faster then a stage 0?? I would be very interested in this information. I am defiantly willing to race a SC tC with a pulley to verify this. Unfortunately I do not have an intercooler though.

 

Where did he say anything about pulley?

I would not go into it either Simplyscion...that race was not a valid comparison due to difference in supporting mods both cars ran. Even then Stage 0 won off the line race.

 

I payed for my ZPI Stage 0 -I'm just wating to get it.

Let me tell you this, if you think you can install a stage-0 and be done with that then it is not for real...

You will end up getting some more supporting mods because it's the only way of keeping the car running dependable and safe. By the time you are done with the supporting mods you will in effect have a stage 1.

That's why a stage 0 is not a real thing. It's only a transitional point until you get all the supporting mods that have to be done to get the car to run dependable and safe.

 

newbie stage 0 install warning thread...read up on it

The only reason why I lost off the line was because of wheel spin, but as I stated in that thread, a loss is a loss is a loss is a loss...I think 3 out of 4 runs of me winning is some good results...its not like it was a one shot deal

 

 

Prove to me why it's not a good deal... They may not be equal in power but they share the same level of dependability that you require for a daily driver.

 

Lets agree to disagree. You are right, race is a race; however, I sill believe that it was not a good comparison of ZPI kit vs Supercharger due to supporting mods. Got to keep it consistent.

I can venture into the whole deal of whether the boost on ZPI kit should be bumped to 9PSI since supercharger needs a 9psi upgraded pulley to run with stock stage 0 kit. I don't argue that but I do ask for SAME supporting mods when comparing 2 products. This is why I say that it was not a valid comparison but a good race non the less.
