Meaning that the intake and exhaust back pressures are equal?

Yes equal but usually more intake boost then back pressure.

intake pressure exceeding exhaust pressure is where magic happens.

Hmm, didn't know that was even possible; that does sound magical!

On my engine my intake boost is more then exhaust pressure anywhere from
1 psi to 4 psi. On another compound DSM Kevin Jewer's 7 second 1/4 mile Talon hes running a much higher rpm then me and a lot more power around 1300HP at 9500 rpm, and at this high rpm hes only 1 psi to 3 psi more back pressure then intake boost.

EDIT:
Engine Load is intake pressure
Primary Load is exhaust pressure

Been testing my new internal fuel system.

My goal was to remove the 3 gallon fuel tank. The tank is to small (need a 6 gallon now) and I really don't like the idea of having a fuel tank inside the drivers cabin. So the last two tanks have been waste solvent added to the stock tank going through my modified fuel system and then to the fuel injectors.

I will have the injectors flow tested and cleaned next spring with the results posted.

I'm also working on the new complete exhaust system out of a 2004 Honda Insight Manual car. I will use the cats and muffler. I will then run my 3"
by-pass boost reference exhaust valve. The valve opens at 8lbs. of boost and will dump to atm. My 2000 Insight has been great for getting information on when to run stoich and for how long to keep the cat happy. Since its a 1.0 liter and my Talon is a 2.0 liter for now I'm going to shorten the lean burn time by 2 and lengthen the stoich time by 2.

Its getting cold here in the PW Northwest and I'm about to switch back to the winter tires and raise the car up 1" to make up for the 1" tall tire offset.
When the snow starts I will add another inch extra for snow clearance. This is going to kill some FE but with the waste solvent working so well I don't really care.lol

You do realize that you have passed basjoos and the AeroCivic in Ecomodder's Top 10 over FE for gas cars, right?

Almost 300% over EPA... Wow

Yeah it kinda makes me feel bad? I don't know if I should adjust the fuel mileage based on without waste solvent or keep it like this. What everyone thinks is what I will do. My last and best tank with waste solvent enable was 40 mpg on pump and was not my best pump fuel only tank. I'm running a higher percent of waste solvent now trying to use some of it up because of storage reasons.

I'm thinking I should do what the bio diesel guys are doing and adjust to pump mileage and show the waste solvent addition in cents per mile?????

yeah, waste solvent is cheating
