I know that the first thing i need to do is work on the exhaust to let it get the air out better. are there any larger throttle bodies that can go on the thing to get more air in it. Im trying to get as much power out of it as i can without doing major work on it, (dont want to have to start tearing engine apart). any suggestions on what to do with getting more air in the engine would be appreciated. Iv seen lots of ideas for a carbed engine but not the EFI's

There is very little out there for these engines. What is out there isn't an easy bolt on and/or doesn't gain much if anything. I am working on a few things that should help, but funds and time are both low right now so things are moving slowly. I can tell you where not to spend your money. Anything before the intake port is a waste until you get the port to flow better. One of the things I am working on is an intake that might help overcome the poor port a little bit, but it's a ways off. I have the upper done, just need to clean it up and get to the dyno to see if it helps. Once that's done I'll start on the lower. Headers and exhaust make a huge improvement, but the headers are a PITA to install because of all the mods needed to the vehicle for them to fit and work properly. One thing you can do that will wake it up a little is advance the timing. 14-16 degrees seems to work very well. I've tried up to 26 and the response improves all the way up to there, but you start to sacrifice part throttle driveability and the ability to run low grade gas. Once you get above 16 the idle seems to want to hunt around a little. With a std. trans it's no bid deal, with an auto it could be a pain. Be patient, parts are coming. Well, actually the plans for the parts are coming. I have no problem sharing what I learn, but I don't have the resources to build parts.

 

Electric fans and replacing both cats with a single highflow cat made the biggest improvement for me. FIPK is up there too.

 

What are the advantages of 14° of timing vs the stock 10°?

 

When Ford calibrates spark tables they have to take into account all possible operating conditions. Therefore they may have a conservative spark table to keep customers out of trouble when operating under extreme conditions, such as cold, dry, low altitude, high engine temp, extended heavy loading, low octane fuel, etc. etc.

Sooo, if you are not at those extreme conditions you may be able to advance the spark a few degrees to get it closer to the optimum spark needed without the risk of engine killing detonation.
