I was just wondering if any one else that has a 2.7 with a power tower has encountered a bank lean code before? I just installed one not to long ago and mine coded twice. It is really a lot more fun to drive now. I also am running the E 3 spark pluggs in it and a K&N with custom exaust. I got a cracked exaust manifold though. Thats next to be replaced. Any input is welcome.

I finally repaired it MYSELF! I guess no one had any ideas.

I am installing a Pacesetter header on my Runner now to fix the manifold issue...

Why not just take the Power Tower off since it's not doing anything since I think even the 4 bangers are direct port injection meaning any swirling of the air can't produce any power period since the air and fuel don't meet till in the cylinder.

It's just a pricey paperweight.

throttle body spacer true info.

1) neither a throttle body spacer or any other device you can install in the intake will -swirl- the air better

ask any true automotive engine designer. any disturbance or change to the airflow is completely and 100% negated by the time the air enters the manifold. buying a spacer on the theory that it is swirling the air better is junk science and you are a sucker

the engine intake is optimized. any changes ruin the design. unless you are bolting a new manifold, different camshaft, blower, or turbocharger, you are not gonna do diddly crap to anything but your wallet


IF swirling the air in that location did anything to the HP and burn, then the intake would 'already have swirly bits built into it' because the manufacturer would be able to meet or exceed EPA requirements for less cost in engineering design of the rest of the engine, including camshaft and valves.

2) a spacer CAN add some HP (maybe three) , but not from swirly bits or flow disruption...it must include serious cooling... none of the junk crap with swirly designs. the hp increase is a factor of temperature. if you keep the airflow cooler by lifting it away from the engine an inch, and the throttle body is chambered and cooled and connected to cooling lines, there is your minor increase.

3) a throttle spacer in a carburetored engine does make more power. not in a fuel injected one. it both cools the intake and increases the duration of the mixing of the atomized gas and air when a spacer is placed under the carburetor

just send me your money, and I will send you some cards you can stick in your wheels to make a vrooom vroom sound if your ass-dyno requires noise to feel manly

save your money


Oh but you say the gains are dyno proven ? well....slap a laptop in the passenger seat and monitor your ECU and do some driving
and compute your gains and post them up.



Here is a quote that sums these up nicely:



"We did a study on these while in College and they do work. However they need to be about 1 meter long before any measurable results can be recorded on a small block V8. Longer for an engine that breathes less.

The only thing they would be good for at a size that actually fits under the hood would be as a phenolic damper, or in layman's terms, a heat isolator. It would take about 2 years at $64 to recover the benefits financially ;-)

(note a damper or a very cold, cooled throttle spacer would work, but as they say, it would take a long time to reap any benefit)

If they worked the auto manufacturers would use them as opposed to tuned intake runners, TB's and ports. "




I will say if you have some old engine with a carburetor, then put the power tower on that, then you would
see some tiny gain. Nascar used to use them to get 1 or 2 % more out of a tank of gas.

for you guys who do not know what an E3 plug is read this

http://www.e3sparkplugs.com/


marketing crap!!

dude go get some dual electrode NGK or Denso plugs

eric-the-red

But they're patented and "Developed by researchers from leading engineering universities", they have to be better

dirtoyboy

WTF is a power tower? sounds like its more trouble than its worth

mkgarrison5

oh yeah of course! just like those Bosch plugs that garantee 5 extra hp!!! wow!! i need to get me a set

Yota Doc

Oh yea, I went ahead and took out the K&N also. That stoped the code. I just put a new exhaust manifold on yesterday, doesn't sound like a log wagon now. I am also gonna go back to the right spark plug. You see this stuff out there, some times you got to try it for yourself to see its crap. I never noticed any power change or gas mileage increase anyway. I will most likely keep the engine stock except for the mild exhaust mod. The truck has got 211,000 mi on it and runs great, I take it and wheel it when I can other than that I drive it everywhere, when I'm not in my service truck. Thanks for shedding some light on these marketing gimmicks.

5 hp per plug x 6 cylinders =

gilby4runner

I would rather have the TRD sticker mod.... 30 h.p. as soon as you put it on the truck

Yota Doc

Cool. There was an exhaust tip a jeep driver made out of a coffee can that he painted red, said it would give you 25 hp and if you put type R on the can it would jump to 50 hp. I think there is a pic of it floating around. I'll have to try and find it.

steanson

Umm....I understand the negative feedback (a la my mustang bolt-on part days), but since when did this forum get so nasty about negative criticism? Cut Yota Doc just a LITTLE slack for Chrissake...can we be a bit more constructive and less ugly? Did anyone actually answer the question?
Good Lord, am I Pre-Manstral-Syndroming today?

Man4God

Yeah, big balls came out of nowhere. Highly critical guy...and that is coming from me, a highly critical guy myself.

Yota Doc

It's cool, I am old enough to know that people have their own opinions and not to sweat the small stuff. I can get a laugh out of it. Thanks though. Was getting a bit slammed, I have seen a lot worse. I feel I got off kinda easy. After all, I did fix my ride. I am out wheeling again. WaaaaaHoooooo

steanson

I hear ya. It just seemed a bit....excessive.
Anyway, we've all experimented with odd mods...I just felt the thread was hijacked and taken in a direction it didn't need to go.
It's all good...as long as you never put pellets in your gas tank.... ;^)

Yota Doc

Yea was getting a bit off track. Never tried the pellets. Have heard of it. Decided it was not a direction I wanted to take.

BigBallsMcFalls

you are welcome

steanson

I LOVE you, bigballs!
you are my HERO!

...why am I not getting power from my tornado? Jeeeez...I can't figger it out....
Dopey.
