if you don't mind me asking rswords, why do you want to get rid of that fuel, i can see to reduce smoke, but that also will reduce boost to won't it or am i mis understanding.

as i said before too much fuel can be a problem and as rswords had explained with better termonology it can actually hinder the flame that is produced by the combustion. which means it leads to more inefficiency than it does power; until of course you see the higher boost levels... he wants to keep the top end fuel that the denny T provides but he'd like to reduce low end fuel as it is hurting his spool up, if you get the right ammount of fuel for air that is present at low end then you'll produce more gasses thru complete combustion than you would from excessive fuel and an incomplete burn. more gasses will porduce higher drive pressures, greater force to drive the turbo sooner and so on. i doubt he has to worry about boost anyways for what he's running a single silver 62 is one hell of a charger

Glad you answered that. In my opinion with big sticks ( 6x16's or 6x18's ) the m2 is the way to go. Less fuel on bottom and massive fuel on top.

It does take some tuning to get it right. When I installed mine I had the starwheel way up. It made it a dog on the low side then when the pin droped down with boost it made like 7 psi more then a stock pin turned to deepest. I put the starwheel down some to get a little more fuel early. Basically it allows you to make more of a difference with starwheel and smoke screw settings. With a stock cone the starwheel and smoke screw are mild adjustments. With the extra depth as well as a shallower end it just adds to the tunibility.

With aboost fooler/elbow I'll be able to tune how fast the pin comes in. I have all teh parts to make some crazy numbers... Just need to get them all working together.
