The dyno charts don't show it but the truck pulls like a tractor right from idle and even below. I measured the slope of my driveway with an inclinometer and it's 12 degrees. My fully loaded truck climbs right up it even down to only 500 rpm without stalling. It vibrates just like a tractor engine. If you've ever driven a tractor, you'll know exactly what I'm talking about. I live and work in a steep canyon and am always crawling up and down the hills in first gear, so this spacer exactly suits my own needs. Here's the dyno run with the tooter spacer. All the sound is the intake because the exhaust was stock when I ran it. http://www.youtube.com/watch?v=H6ofUy8_-6Q And an acceleration run, same spacer, stock exhaust. http://www.youtube.com/watch?v=hvIBURPwtXw Greg |

Here's the prototype on the manifold...
It doubles the length of straight runner section before entering the head as well as adding a little more volume to the manifold. This with the spacer on the engine. Installation is stupid easy. There's tons of clearance everywhere, and even the oil dipstick tube fit perfectly. You can hardly tell it's there because it's covered up by the fuel rail and the wiring loom. With the cover on, it's literally invisible. I bet it wouldn't even be noticed on a smog test. I drove it around today, but couldn't really tell any difference, because I'm so used to driving the tooter ET manifold and the larger Corolla throttle body. So that was giving up a lot of advantages. Still it ran good with no issues. I had disconnected the battery so that the ECU could adjust back to the different stock manifold, the different throttle body, and to the spacer as well. All three being changed at exactly the same time caused the ECU hunt around for quite a while trying to figure out the right idle. But it eventually stabilized and the engine runs just fine. I'll see about dyno runs this week, if I can find the time. Greg |

Awesome!
Hope the dyno shows something the butt dyno doesn't :)

My wife has been driving the car all week so the ECU is all dialed in now. Today, I finally got a chance to drive the car a decent distance, and it definitely has more low rpm torque right from off idle to 2,000 rpm. I did my "clutch test", and can let out the clutch pretty quick with no gas and the engine won't stall. I used 2,000 rpms as the shift point to get a good feel for how it accelerates at low rpms and drove it at 35 mph in 5th gear to see how it handles the low rpm load. Feels like driving a little truck.
My wife had said that the exhaust sounds "funny", and after driving it today, wow... it sure does! Up to now I had driven it only about 5 miles after first installing the spacer, and had babied it not knowing how it was going to work. So I didn't hear what it sounded like at higher rpms. When you get on the throttle, the engine makes this really strange rrrrrrrrrrrrrrrrrrrrr sound like a 4 cylinder motorcycle engine. So the spacer actually did change the operating parameters of the engine quite a bit. Dyno testing will be this coming Monday the 3rd if Harry can fit me into his schedule, so we should get to see the results soon. Man, I can hardly wait... Greg |

Took the car out again and on the freeway for the first time. Flat out acceleration there's nothing at the top end, but then I'm used to the 1ZZ throttle body with the tooter. It cruises with very little throttle At 2,500 to 3,500, and feels great, so I'll begin taking gas mileage readings when I fill it up after the dyno test on Monday.
On the bottom it undeniably feels stronger. I did my "driveway test". It's a 12% grade and from a standing start, the car goes right up at only 400 rpm with no bucking or stalling. The road that goes to my house has a really steep grade, so I also use that one as a test because I'm constantly going up and down and know exactly how it feels. When purposefully short shifting out of first down to only 1,000 rpm in second, it accelerates right up the hill with absolutely no bogging or bucking or straining and without needing a lot of throttle. Now I'm starting to get excited about this as it's passing all of my torque tests with flying colors. :) But my impressions are highly subjective. That's why we need the dyno so that we can see some real numbers. Greg |

very important to have low end torque, for um... red light acceleration. you know, when leaving red light and trying to get up to proper speed limits and economy speeds.

Ok. Just got back from Harry's shop...
(ta da ) Red: no spacer Blue: with the tooter I.V spacer Both runs were done with the same short ram intake, the same air filter, the same stock plastic intake manifold, the same stock throttle body, the same header, and the same axle back exhaust. The tooter I.V intake manifold spacer was the only change. This is similar to the results I got with my Tacoma. The I.V spacer lowered the torque peak from 4,100 rpm down to 3,650 rpm as well as fattening up the torque curve a little. Not too bad for just a simple bolt on part. Just for context, the bone stock torque peak is 4,400 rpm, so the intake, the 4-2-1 header, and the Magnaflow exhaust had already lowered it by 300 rpm. The spacer lowered the peak by another 450 rpm for a total of 750 rpm. Greg Last edited by tooter; 02-03-2014 at 05:23 PM. |
