Intake HP increase questions

I have been reading through several forums related to HP increases with the 22re and found that 1)swaping sides with the battery and intake or 2)replacing the factory plastic peice going from the intake to the airfilter with a larger 3" peice are some great and cheap HP increases.

Here are my questions: Has anyone tried this yet? Has it helped? I saw a pic on another forum where the guy had a U shaped peice going straight to the AFM into a cone shaped breather on the passenger side but the AFM wasn't plugged up. Apparently you can bypass the AFM by hooking up the fuel pump to a relay? Is this true? And would it have any effect on the ecu or throw any codes by doing this?

You need the AFM for engine load sensing, if you bypass it, engine wont work properly. Also hp increase from a filter is neglible.

any gain - which is UNLIKELY-- would be so slight, it wouldn't be worth the efforts !!!!!!

I was also reading where one guy cut a 3" hole in the side of the airfilter box then ran a 3" pipe from the box to just inside of the grill so it would suck in the cool air from outside of the 4runner as opposed to the hot air under the hood. What do ya'll think about that?

a 4Runner gets is air from the bumper or grill in stock configuration. Even my 87 hilux got its air from the headlight area. So my opinion is waste of time.

if your looking for more power id get a cam and header with a 2 1/4" pipe.
that will give you a very noticeable improvement.

I posted a few months ago about HP gains with keeping decent mileage. head / intake / exhaust manifold
so i did the gasket match porting on the intake manifold and put in a engnbldr 268C cam, stuck with stock ehaust manifold but went 2 1/4" after that. I really liked the gains i got. I am still on the first tank of fuel so not too sure what the milage is but the power is better. Oh yeah this is all on an 86 pickup with a 22RE. The cam works fine with the ECU. Nothing was done with the air intake...all stock.

I have an 88 22re with a comp 260s cam, pacesetter header. 2 1/4 inch exhaust, flowmaster and the K&N cone filter kit (which im probably guna get rid of) . I never felt the actual gains since the truck has been like this since i got it, but i know i beat my buddies 22re's

My 4runner already has a mild upgrade on the cam. Not sure about the duration. It was already installed when I got it. Plus its bored out .20 with a 2" exuast and a turbo muffler. I also have the cat off of it and the EGR valve is blocked off. It has pretty good acceleration for a 22re but it has some trouble keeping its speed on the interstate going up hills. I was just trying to think of something else to sqeeze out some extra power.

do you have a tach?
i think my main problem holding speed is the gay auto, i can push it almost to the floor in OD at 2500rpm and hold my speed on flat ground or i can take it out of od and run 3,000rpm at like 1/4 throttle up hills no problem. they key for me is to be over 3,000rpm. If im running over 85mph (yes i can do it) it will stay in od up most hills becuase im at 3200+rpm.
