Not really concerned about the numbers, just wanna know how ya made a full pull on a stock map.

Put the throttle WOT! How do you think? Seriously, Engine is still rich 11.2:1 on Air/Fuel ratio. It just goes to show how close Mercury gets them......They target a barn not a bullseye.

Panther

11.2.... WTF... No wonder those 575's suck down fuel...... If it's 11.2 with good flowing heads what in the heck is the ratio with the GM heads....

Althoug, I know a couple guys who modified their 575's without changing anything and they now how holes in their pistons...

So are the mills on the way east yet? He must be tweaking these things more than they do the space shuttle!!!

You hit it on the head. Working on it. We had to write our own program for the fuel injection so it can be mapped.It's been alot of long nights bro.

Panther

Seems like injection is great on factory motors but everytime you fart on a modified motor it's a heck of a lotta work...

Theres something to be said for simplicity, I like Holleys more and more every day!!

somethin's always goin wrong with an OL

Well there you go, your wife would get biitchy too if you farted on her. All that mathane isn't gonna give you any more power anyway

Panther

Methane is combustive...it'll be like putting the motor on Nitrous!!

Sak, go fart on your motors so you can run a number on the dyno and get that pig in the water!!

Wait til Nick sees this!!!!! From a fountain guy.
