Got a selling price set yet? I couldn't spot mention of $$s in this thread.

nice .65HP and 3.2lbft torque. now if you can get the production price and kits together.

From the original concept on November 29th to a dyno tested prototype took only a little over 3 months and that was with the holidays. So if all goes well, I should have finished products ready to ship in another month for a total elapsed time of 4 months from virtual concept to the reality of a finished product ready to sell. This is the advantage of a microbusiness where just one person calls all the shots. Greg |

The negligible horsepower increase is only incidental as this was not designed to be a top end high performance accessory. The purpose of this spacer is to make regular daily driving easier because the engine doesn't have to work as hard at low rpms. And the increased torque peak really isn't all that much either. Most all of the advantage comes from shifting the whole torque curve down lower in the rpm range. So as the two torque curves are climbing, the spacer curve remains above of the baseline curve. This spreads the torque increase over a larger rpm operating range. This mod is for just regular low rpm daily driving. Greg Last edited by tooter; 02-03-2014 at 08:07 PM. |

Anyway to overlay this with a tooter dyno as well?
Btw madness on the midrange gains!

The tooter manifold with the larger throttle body makes 111 horsepower, so it's graph will be a lot stronger at the top. It would be run 16 with the plain tooter intake manifold and the 1ZZ throttle body... ...and run 23 with the stock manifold and the tooter I.V spacer. Longer intake runners making more torque is a sound mechanical principle that worked out really well on my Tacoma, so I figured, heck, why not for the Yaris too?

If you have the resources, you should experiment with different spacer sizes to find the optimum length. I'd be curious to see the different outcomes.
And then run them all on the dyno, on the same day so there is no discrepancy between the variables. |

I like the bump in torque and where the bumps are in the band.

I'm very excited about this spacer. Most of my driving is done in this rpm range, and will make the 1.5's acceptable torque even better.

There's something that doesn't show up in the dyno runs, and that's partial throttle performance at extremely low rpms right down to idle and even below. This is because the dyno runs done by mashing the gas pedal to the floor at 1,300 rpm in third gear. This is an extreme condition that is not encountered in normal driving. Very low off idle torque is exceptionally good especially when taking off from a stop with a manual transmission. On level ground even if you let out the clutch and forget to use the throttle, the engine doesn't die. Instead the car slowly moves forward without any bucking.

In the meantime, can you source a shipping quote to L0P 1K0 Ontario, Canada? Preferably USPS.

This is just a hobby I do on the side in my free time off of work. Dyno time gets really expensive when your car is on the machine and you're trying to swap out parts. Adding the cost for new CNC programming would make it unpractical to make a bunch of different sizes. Anyways you can simply extrapolate the difference as a one inch spacer would make half the torque as a two inch. I picked 2 inches because that is the thickest spacer which will work without interfering with the engine peripherals like the oil dipstick tube. The two inch simply drops into place like it belongs there. Other intake manifold spacers sold like this one for a Toyota Tacoma V6 are usually only a half inch thick... ...while the tooter I.V is like stacking up FOUR of them.

If Its Not Blown It Sucks

How about a 1/2" spacer for between the Blitz and the head? I haven't had a heat soak situation yet but this might be a pre-emptive strike. If possible, how much and how soon?

Bummer great mod, but out of my price range right now. I'm curious Tooter, what do you think the spacer would yield on a bone stock Yaris?
