Some new threads - finally! The new Mod from Doug at RC Acura.

Here are some educated guesses:

An internal combustion engine models as an air pump - more air in allows more fuel in, and when ignited optimally, the resulting flame front produces more power - a simplistic desc but adequate for this context.

So, to get a 15 HP (gross) increase, the unit would have to play around with the folloowing variables:

1) Spark timing - spark maps are set in consideration of emissions, power, fuel quality, longevity (comb chamber and exhaust valve temps), etc. It is possible to lean out the fuel curve to produce power, but one runs the risk of frying a valve.

2) More air in: Anything that can optimize and increase the fuel quantity or velocity has the POTENTIAL to increase power - emphasis potention. Intake is a dunmaic model - speed, quanity, vortext characteristiucs (swirl) plenum design, etc.

3) More fuel in (works with #2). Enrichment can actually decrease power unless air is added optimally. Plus, over rich can cause exhaust valve damage if enough of the flame front is still burning as it passes out of the comb chamber past the exhaust valve.

4) Faster evacuation - works with 2 and 3. The basis of headers - smoother and more complete evacuation of the comb chamber can allow better hi end power. Doubt that the mod bolts on to a bolt on (the exhaust).

I am staying open-minded, but I am going to give this "magic bullet" a very long look and think before I bolt into my car. I own my car - no lease, no bank note - I am not inclined to be first out of the gate on something like this.

If it works, and it doesn't compromise the car, I am down with it.

The interesting part really isn't the claimed 15 hp gain, its the claimed 20 lb/feet of torque across the entire rev range. Gaining 15 hp is a lot easier then gaining 20 lb/feet torque.

 

The gain across the entire band is what has me most ineterested. I initially thought it was some form of change in the fuel mapping, but some one alredy posted that that wasnt the case.

It was stated that this modification would work in conjunction with I/H/E that many people already have on their cars, so its not a replacement for any of those components. My guess is if its not some form of ECU or piggy back ECU modification them maybe its lightweight pullies, but Im not sure. Either way, I wont be jumping into anything right off the bat. I'd like to see what it is before I make up my mind. If it is some form of ECU mod however, I dont think it will find its way under my hood. We'll see come October.
