This may not work exactly like I plan but it is my target. So far no one can come up with a reason why this will not work. In fact the extra nozzles don't come on until boost is there and most of the time that will be in open loop. If not that might be something to change. But I think the point of open loop is designed to fit the EPA cycle.
Now the CARB tests do not exactly match the EPA. They couldn't because there is a lot more requirments like cold start and evaporation.
I'm real excited over this style of tune as it gives me that advantage. I' m just looking for a controler that is not to pricey. I had hopes for the E manage with the optional nozzle harness but they don't seem interested in talking to me.
That Australian unit that Hymee runs on his car interests me but it is too much money. Plus they are in some sort of reorganization. Of course if price didn't matter we could use the Motec. It might be that I build a unit myself, copying what I likeabout each of the others. I have a racing freind who is capable of doing that.
What the hell did I just say? That's the sort of thinking that gets me in trouble. If I don't like it, I'll do it myself. Now I know everyone does not wait around for me to develope another product. I've come to realize that now. Just thinking out loud, don't worry.
Intake temps?? Well my units normally add about 70 F. On this system I'm looking at getting under ambiant. I have to run the caalcs on the latent heat of evaporation fo this set up and when I do I'll give you the answers. We were just going over the equation for this today. Still need to look a few more things up to finish it. Then estimate the mass flows. Since it's not really something we need to finish the product it is a minor priority.
At the moment we are building the new blower dyno. I took some pictures today but they were not good enough. I'll try again tomorrow. All you can really see right now is the basic drive unit. But it is impressive, weighs 1500lbs by itself with the speed adjuster and gearbox.

Hmmm was not aware that the Hymster had put a $$$$ value on his system , maybe you can fill us in :D
He is allways reorganizing something or someone
especially when hes playing pocket billiards j/k
cheers

If intake temps become a slight problem under load there is always water/alcohol injection which has come back in vogue(?). And why the emphasis on the "No!", Rich?

L&L I ment his piggyback controler, not his SC system. I think it's called TSI.
CRH, I don't know why I wrote it that way but there is nothing to be had by taking the belt off. I mean really nothing. It can't change a thing. The engine has no idea that it is there. By running in a vacuume it consumes no power, it is not blocking the exhaust or intake in any way.
Besides it will probably be running off the same belt as the AC. I know that is the losded belt but I believe it turns off when the engine is fully loaded. It reads that load by manifold vac. So when it goes positive the belt is only running the SC.

In essence it will be similar to a wet nitrous kit? So without an ECU you could run enough boostup to only the point where you'd need to retard ignition?

I have to believe that some sensor or combination of sensors will detect something askew. That will have to be something we trick it into forgetting about. I can't say what it will be because like I said we haven't done it yet. But The way I plan on doing it the stock maps will remain intact. If this method works then there will be no CEL and the car will run exactly the way it did until it goes positive in the manifold.
My SC is the only one that can do it this way as we will not bother the stock injectors. By using two new injectors on the inlet of the blower we will get the advantage of exceptional mixing and distribution. Added to this we reduce the temp of the intake charge without an IC. These things will not be viable with other types of blowers. In fact the turbos are push through, only Hymee and myself use draw through.
Hymee's is a screw type and not condusive for passing fuel. It can, but it will not homonginize it with the air. Too much surface area to sheet the fuel on.
They do it on dragsters but efficincy is not the goal in a drag race. They like to burn up 7 gallons every quarter mile.

Ok, I musta missed something out there. Am I hearing correctly that the Greddy kit will not pass emissions, and that it may well be an issue for other FI kits?

hey richard, i know it's generally not a good idea to send fuel through an intercooler, but do you think it might work to use maybe a pwr wta barrel intercooler with one of these s/c's?

ah okay am i not speaking english or are you guys playing me? junkie said "id like to put one of these in an fd" richard said " yeah you and fred both" capische? 
insinuating that fred had suggested trying one of these in an rx-7.

i wonder if we can run one through an intercooler for the flow and boost pressure, then run maybe a single or dual blade after the intercooler for the atomisation/homoginisation?
