Assuming all the instrumentation is accurate, Boost (intake) pressure will NEVER be higher (or even equal to) Exhaust back pressure on a turbocharged engine while under boost conditions.
It is this simple: You CANNOT get something for nothing.
Can you inflate your bicycle tire w/o expending any energy to move the pump handle up and down? No. Will you create HEAT in the pump as you compress the air? Yes.
We all agree (and know from common knowledge) that friction creates heat. No energy input = no friction = no heat. Efficiency is a function of the amount of energy WASTED as heat. If a turbo generates boost pressure and heat, it needs energy to do it, that energy comes from the crankshaft via the rods and pistons PUSHING the exhaust gas outward.
If you actually measure the exhaust pressure in the MANIFOLD (between the valves and turbo) and compare it to the pressure in the intake, you will prove to yourself that this is true.

Just imagine if it was actually possible!!!
Who needs Axial Flow? Who needs rotors? Just use some electrical current to start it and it goes and goes faster, and faster and faster... be careful revving this one in neutral, it'll spin off until it self destruct.
The infinite power-r-r-r!!!
We could rule the streets... Not streets, the racetracks... No-o-o the UNIVERSE
Muah ha ha ha!!!

got carried away a bit. In reality I just want a little bit more horsepower for my 8, That's all...

Hi!
I guess this could help with this project?

What is it that tells me you didn't read the first five pages much less the 200+.
Do me a favor and read the first 5 and get back to us.
The alternative would be a lecture from RotaryGod.
And that might be longer then five pages.

Between Richard's SC knowledge and MazdaManiac's tuning wizardry, together they could, dare we say, rule the world!

How far is it from Phoenix to Chatsworth, CA anyway? Where's the paypal account to contribute gas money?
SO, WTF happened with guitarjunkie's tuning efforts? Why haven't we seen any results yet? The hardware has been available for at least a month, no? Tuning this thing is not that hard - especially with the IntX. Take it from the guy who refused convert to it for the longest time - the damn thing works like a champ. The eManage Ultimate will no doubtedly also work. But, is there something else going on here? Plenty of people are running EMS now and tuning it on their own with little to no experience.
I'm incredulous.
Really. The EMS issue has been solved. What is going on with this project? What is preventing the completion? What is the issue that is standing in the way? It's no longer the EMS.
Instead of dodging, why not answer the question?

The answer is that the car is in the body shop and that's all I'll say.
And no, the EMS is not solved. I'm taking offers on the Decepter X by PM.

re-goddam-diculous....
I suppose the EMS situation IS solved for turbos, but apparently not SC's. How can it work for probably close to 100 turbo'd 8s but not your supercharger?
Please, illuminate us. I find this constant dragging on to be frustrating - and I'm not even waiting for a AFSC! But if I were waiting for it, I'd take this coy gamesmanship regarding the facts to be infuriating - and possibly a sign that something is amiss. Left to my own, I'd have to conclude that there is no plausible reason that a SC would provide any more of an EMS challenge than a turbo. Therefore, I see no reason why we haven't seen this SC in action yet. If I'm wrong prove me so. I'm not afraid of being wrong in a public setting. Neither should you be.
Yes, I'm hounding you. Yes, I'm being an *** about it. But, I think I have a right to be. I've shared both my successes and failures with the forum. I expect anyone posting outside the 'vendor' area to do the same. Outside the 'vendor' section you are a member of the Community. The Community is here to share knowledge. That goes double when folks have been waiting patiently (remarkable patience) for your product.

How do you have a right to criticize him when you have something already and have no intention on buying his product? Have you put any money into this? .. Why stir a **** pot?He seems to have been very honest with everyone. The "solution" didn't work and he didn't feel comfortable releasing it with it and he's stated that he's looking for another solution. I find that more comforting than the blown seal threads we saw when greddy first came out.
He wants to get it right the first time, not run a trial and error situation on actual customers. I don't find anything wrong with that. I wish more vendors were this open and honest about things and rigorous about testing a product.
People have been waiting a while it's true, but really what's a little longer?
RP,
Just to provide a counter point to MadDog, I plan on buying your product (assuming it doesn't break the bank) and I am waiting patiently... and I feel I have nothing to bitch about. Continue the good work...
