Cool

Wade, it sounds like you and I could be best friends. I don't mind EFI all that much, it makes good low and mid rpm torque. It is good for an extra 2-5 mpg. But RARELY IF EVER can a fuel injection system provide maximum horsepower for an engine. Most of that is due to excessive atomization and poor air fuel mixing that happens with port fire fuel injection.

You get a denser fuel mixture from a properly tuned intake and carb set up any day. Hell, we tried this on a hot rod rat engine. Made 614 hp on gas only with a Victor manifold and demon carb. We went to a fuel injector to make the engine look more polished, power dropped to 570. He paid shops nearly 1,000 bucks just to get the power up to 586.

Gotta love all those who swear EFI is the best, because I smoke em all the time on the street, at the drag strip, and out on the autocross. Smoke em, and leave them for dead.

I really like things simple, and I am getting better and better at tuning carbs. Although I learn something EVERY day. That's cause I like to hang with guys that make speed.

Good luck to you.

And for all you EFI lovers, read my speed secret number three entirely through. Then realize that the computer does not "see" the intake manifold nor the cylinder pressure, so it cannot properly enrichen the fuel density to take advantage of the racing cams that make the big power gains. So plan on buying a lap top and custom programing a whole new fuel curve algorythem if you plan to keep up with Wade.

Cause he will be smokin you, like I am smokin EFI's in Portland.

Good luck, and don't take me too seriously, I am baiting the EFI crowd to see if they know what they are talkin about......
