To clear something up, I'm only passing on what was suggested to me. My car is running way rich at WOT. Since it's stock with the addition of a J-spec intake cam, a K & N drop in, and some exhaust mods, We are assuming that the WOT settings are set rich to keep from detonating. The injectors should not be anywhere near there maximum duty cycle with the stock horsepower. With the amount of fuel I'm getting, there is a large amount of room for moving more air in without a corresponding increase in fuel. The first thing the techs that worked on my car said was that it would just about take a 40 shot without enrichment. They suggested an RPM window switch on the system that would only kick in past 3800 which is about 300 RPM past where the stock system starts dumping in the fuel. That is not a lot of NOS, and the stock timing is retarded enough that there is no real fear of detonation.

The other thing that was suggested was to add a Unichip and reprogram the ignition curves and the WOT fuel curve in order to maximize what we already have. It would have to be set up for the mods on the car, so it's best to have all the cams, exhaust work, cylinder head mods, air intake and what have you done before it hits the dyno and gets tuned. The same piggy back can be used in a turbo application and since one of the pickups that they can use during testing measures duty cycle, they'll be able to tell just how well the stock injectors will work.

To my knowledge Tri-point chose not to go this route but instead used a stand alone fuel enrichment to control extra injectors. They did not address timing or the limits of the stock fuel system since they did not do anything at all to the stock ECU. It's possible that the stock injectors will work with 6 psi but no one has put a piggyback on and actually tested it. Tri-point did try to put a rising rate regulator on the system, but it didn't work. The injectors need more pulse width which the stock ECU will not provide. Until the stock limits of the fuel system are tested using a device that will control the injectors to their limits, this is all moot. No one has done this yet, so no one knows.

Personally, I'd rather have a matched set of 4 injectors that are slightly larger than stock than some add ons. I'm waiting to see what BEGI does in their testing. Maybe they'll push the stock system to see what it's capable of before they add anything. They are still 8 weeks or so away from being able to sell kits. Still in fitting and testing.

There's possible explanation for unbeliavable torgue numbers.
If any of you guys ever run car on a dyno THROUGH gears(shifting at redline) you get HUUUUUUGE torgue spikes. I had like 180 lb/ft from BP engine in my old Escort, but it's just at shift points.
There's no way stock MP3 has 200 lb/ft, but sure can have it at shift point. Later I will try to find chart and see if I can use digital camera to "scan" it.
As for 98 hp base line....I wouldn't care, cuz incremental horsepower is what important here, +70 hp is nothing to sneeze at.

Sir Nuke

if you look at the numbers in the chart.....they match up with the advertised STOCK hp and torque numbers in METRIC units....Kw and Nm.

then they go on to talk about HP and Ft-Lbs later on.....sorta confusing....especially since they don't put the units after the numbers....leaves you to ASSUME things...and you know what happens when you do that.

Sir Nuke

he he he.....yep ya sure do!!! :{D

and those poor suckers can NOT use the saying..."well hell it aint rocket science ya know!" LOL LOL
