tooter's manifold adventure...

[cali yaris]

because no material is removed, just compressed.

I don't know about that. Look at the welds; they look filed down. Sorry, but overall that just looks terrible to me. I know you'd want an honest opinion.

Hey Garm

That pic of the dirty manifold and the clean one aren't of the same part. I just took a pic of one of the dirty manifolds to show the contrast. The texture of each of the welds on the manifolds varies widely. I suspect that they were done by hand as they are not consistent as with automatic machine welding.

The horizontal line isn't a weld because it's a one piece casting. That's a thick seam from the two halves of the mold. And there has been no filing on any of the welds as it serves no purpose. When it's installed on the engine, the casting marks aren't visible...



I haven't bead blasted this tooter yet because it's on the daily driver. Just rubbed on it some with a scrubbie to clean it up a bit. I'll post up some more detailed pics tomorrow.

The shot peened surface doesn't even need a clear coat as the small pores in the surface are closed up. I wanted a surface that I could process simply all in one step and that would hold its appearance over time without any maintenance.

The new order of SS shot came today so I'll be blasting all I want tomorow.

[tooter]

With lots of beads, I can blast all I want. The beads haven't become polished from use yet so this surface is a little more matt than it will be when they are. I'm just practicing to see how the whole setup works.

Picked up two more flanges and blasted one just for fun while I'm breaking in the beads...





You can see the Dremel cut out lines on the inside edges of the two outer ports. I'll be hitting them with the grinder and then blasting the finished surface.

Shiny! I'm assuming these are going into retail units?

[packetrace]

how much do you plan ?

Hey Cranky,

It's actually quite matt compared to the raw shiny machined surfaces. However, the durable shot peened surface will retain it's appearance over time.

Yes. Some will go to make complete manifolds, and some will be do-it-yourself parts kits to which you add your own manifold.

To me they look really nice I like the surface finish :)

One at a time!

None of the throttle body adaptors have been machined yet. Only the two flanges so far. I'll be kept busy for a while cleaning and blasting the old manifolds and getting them welded up.

[tooter]

tooter two is ready for the welder...



It was just an experiment filling the letters with paint. It'll get burned off with the welding. But it doesn't matter because everything gets bead blasted when it's done anyways.

On to tooter three...

[packetrace]

nice thing :D

[tooter]

As of today I'm officially a yarisworld tooter vendor.
I'm just on a month by month basis, because I don't think this business is going to last very long before it folds.

There's supposed to be a green vendor tooter on my nameplate, but I don't think that's going to be happening.

I'm offering for sale as a complete kit:

1. one welded, assembled, bead blasted tooter manifold
2. one matching throttle body adaptor for either 1NZ 4 bolt 48mm... or 1ZZ 4 bolt 51mm
3. one OEM flat throttle body adaptor gasket
4. three throttle body adaptor allen head bolts
5. one OEM O ring throttle body gasket for 4 bolt 48mm... or one OEM flat throttle body gasket for 4 bolt 51mm
6. one OEM O ring intake manifold gasket

$425 +shipping.

Also offered is a tooter do-it-yourself kit where you supply our own manifold, consisting of:

1. one tooter intake manifold adaptor flange
2. one throttle body adaptor
3. three allen head throttle body adaptor bolts
4. one OEM flat throttle body adaptor gasket

$250 +shipping


(picture us of an unblasted manifold)

I also offer a tooter manifold with no adaptor which fits a 1ZZ 3 bolt 51mm throttle body for $350 +shipping

You can use all of the same stock intake manifold bolts as well as the 3 stock throttle body studs and 1 bolt on the tooter.

The bead blasted manifold will readily accept paint, powdercoating, or ceramic coating.

If you have any questions feel free to call or email me and I'll be happy to answer them:

Good luck to you as a vendor Greg

Now go and introduce yourself/product in the Sponsor Classified Forum.

Tried to search through this thread for comments on gas mileage to no avail... Any significant difference either way?

[suckerface]

He mentioned during his testing over (I think) two tanks of gas that it didn't make any significant difference, possibly a bit higher. It didn't drop at all, however.

[CTScott]

Hmmm. I might have to order one of the DIY kits to experiment with one of the 2TZ superchargers that can be readily found for about $300.

There was a slight increase but it was not significant. I took the mileage readings from the last 699.6 miles @ 19.508 gallons before installing the tooter,and the average came out to 35.86 mpg. I didn't count the fillup that had the stock dyno runs in it so that the average wouldn't get dragged down.

Then I took the following 514.0 miles @ 13.133 gallons running with the tooter. Also not counting the fillup that had the the dyno runs, and the average is 39.13 mpg. Not exactly in hypermiler territory.

So even with the peak horsepower and peak torque being essentially the same as the stock manifold, the comparative dyno runs clearly show that the tooter underperformed the stock manifold under wide open throttle conditions. However, it does work very well in normal every day partial throttle driving conditions. When you let out the clutch taking off from a full stop it hardly takes any throttle which is really nice when driving in traffic.

[baseballfan416]

39 vs 36 = about a 7-8% gain (3 of 36 = 1/12th = 8.5%). That's pretty legitimate!

The reason I'm intrigued by this is because here we have a product that was essentially taken off of a 1.8liter corolla engine (correct me if I'm wrong). That engine, in it's time, was rated 30city 40 or 41hwy mpg? Combine the better "breathing" capacity with a lower displacement and I think this could be of particular interest to the hypermiling crowd. In a way, you don't necessarily want more power to get better mileage, but rather you're trying to make the engine run more efficiently. Hence the -1hp +1tq is an afterthought if it improves overall drive-ability.

If I had the money, I would get an MI pulley, some sort of an intake manifold gasket (to lessen heat soak), this product and either keep the stock tb or get the mystical corolla tb that everyone is so infatuated with. Combine that with an injen intake (assuming anyone ever responds to my wtb thread) and I bet I could break 50-52mpg in the summer (44-46 avg this past summer).

Of course, this would all cost about $700+ so even with a 5% gain in gas mileage, I'd have to drive the car 10-14 years to make up the difference in saved fuel cost.
