any body got any experience with the LC Engineering Throttle Body Spacer Kit? a friend of mine has a throttle body spacer on his dodge and he said its action! thanks

 

Do those things actually do anything? I guess I've never understood why the location of the tb would make a difference. Is it just because of heat?

I think the consensus is that they are ineffective.

 

Makes a good paper weight.

In your reference, what does "he said its action" mean??? God, I must be getting old, and I haven't even hit my 30's yet.

 

I have read that throttle bodies can be somewhat effective. But it depends on what motor. Probably wont make a difference on the 22re because its not really starving for a better air, fuel mixture. I had one on a 4.3 in a '89 S10 and it seemed to help a bit. I doubt you'll ever get more than one or two ponies and a extra mile out of a tank.

 

How can a spacer give any benefit? i never seen the point in using one unless you need clearance for other parts.

 

adding a spacer behind the throttle changes the tuning of the intake system in regards to how the resonance of the pulses in the manifold cause positive pressure waves that can aid in cylinder filling at a particular engine speed.

Do a google search using the terms; tuned intake manifold , and check out how this works.

It is likely that adding a spacer would have very little effect at best, and could actually tune the system to a less beneficial engine speed and hurt actual performance.

Either way the effect would be minimum.

 

I think the larger the displacement the more effective they are but still minimal at best. If you were to do a bored out throttle body, a spacer, a k&n or similar intake, a header, freeflow cat, and good exhaust you would notice a difference, but IME adding one thing at a time doesn't really show any instant improvement. The only engine I know of that a spacer was somewhat noticeable was my buddies 4.0 HO in his Heep.

 

If adding an two inches to the TB would have increased hp, Toyota would have done that at the factory. Jeep on the other hand...

 

Ditto we put a TB spacer on my friends cherokee and it brought new life to the 4.0, the manifolds on those are very restrictive and the spacers also have a spiral design ciped into the inside that spins the incoming air a bit.

 

 

Actually, Toyota did redesign the intake manifold on later 22RE motors - you'll notice that the early necks of the plenum are angled. Later generations are straight and have less restriction.

I'd be willing to put money down that this spacer does absolutely nothing for HP.. There are better ways to waste.. I mean spend money..

 

alright everyone thanks for the info. i guess i aint gettin that spacer. i was just interested in sum cheap power? any suggestions?

 

The best cheap power is to keep your junk clean and well maintained.
Proper tune up - valves in spec.
Advance the timing a bit, 2-3 degrees.

Unfortunately, with 100-125hp, there just isn't a lot of free power in these things... :-)

 

reliability=no power...live with it.

A carb spacer on the other hand does actually do something though.

 

I disagree, we've got factory 2.4L motors putting down 285 hp now (see the new SRT Caliber) - perfectly reliable. Perhaps not an apples to apples statement...

Search for "mods" advice for the best bang for your buck on these things.. I do agree with above, however, than unless you really dump some money into them (like crazy money) that the best you can hope for is 10-20% improvement.

 

I would say Cummins is about the only thing (IMHO) that actually puts out a decent amount of power and reliability...although that is diesel.

 

It's called "Volumetric Efficiency", Get the air in, get the air out. search that for the "truth".

Thanks, Kiwi

 

The 07+ Tundra puts down 381 hp and slightly over 400 ft/lbs. That ain't bad as it's emission legal... It gets 14-18 mph based on realistic ratings.

Doesn't the new Corvette put down over 500hp with around 6.0L?

I like the Cummins engines too - real work horses.. They're cheating though, increased volumetric efficiency because they're feeding it at least 2 atmospheres of air (turbo charged).

Sure beats the heck out of late 1970s and early 1980s power outputs for the same size of motors...

 

lol yeah. But their bottom ends are bomb proof. Put a better turbo, bigger injectors, and it's unstoppable. Do the same to the Duramax or Powerstroke and they are bombs waiting to happen.

Yeah...the corvette gets pretty good gas mileage too!
