Thinking of puting a throttle body spacer in my 91 Sidekick...has anyone done it and did it make as much a difference as some advertising has said...."extra 5 miles per gallon and horse power boost"

I've never done it myself, but I know people who have and it made a significant difference.

Geez, I never thought of that on a fuel injected engine...

I mean the 1.6/8 uses throttle body injection, so maybe it would help.  Be sure to do a write-up on it, with pics!

i was thinking about a tornado air thingy.  i have heard them make a resanable(sp) increase in power.

I'm working on this -- although like everything else I do, not too quickly

It should make a difference, but it's tough to predict what the difference will be.  Most everything I've read points to the idea that a spacer will move the power curve up the RPM range.  You may see increased HP and TQ, but it will be at a higher RPM and you may see reduced TQ at lower RPM.  Apparently, drag racers were big into spacers; I guess so that they could control traction off the line and have a little extra HP later on once they were hooked up.

Anyway, on a TBI unit like mine, I think it may make a difference and if it gives me some more HP at a higher RPM that might be good for some highway driving -- lots of mights, ifs, and maybes.

I'm working on replacing my clutch fan with an electric right now, but if no "repairs" come along, I'll get back to the spacer.  I have one made from wood, but I may look for some phenolic material to use.

Let us know if you try one.

FWIW, I didn't buy one of these but made something I thought was similar out of some sheet aluminum.  I didn't see any difference, but that could just be because I made a crappy substitute.

even if the power comes in later itl still be good..these things rev prety quickly and after the inital start im prety high in the rpms anyways..gota give it some gas to move u know =)

I have a big piece of 1" thick ally plate ready to make one but like everything else its on hold as I'm expoecting to move house next week (its been next week for sooo long now ) If it doesn't give any more power at least it'll move my intake nearer to my airbox after the bodylift. might even manage to connect it back up again. As an aside I fitted a spacer in the inlet tract of a bike I used to race, gave a 3/4 bhp power loss right the way across the power curve .
