Yaris Intake Manifold

[richardholdener]

Hope there is no confusion, but the intake for the 1.5L Yaris is different than for the 1.8L Xd (or Yaris TS). I hope the Yaris TS and Xd will share the same design, but I will need to check packaging on TS before we know for sure.

Patiently waiting for intake.....the 1.5 needs something liek this badly.

Sorry I meant 1.8......the xD really us under powered for what it weighs.....that is the only complaint about the xD you will hear from owners.

I'm just a bit doubtful if the stock ECU will be able to handle the better induction without throwing a code. It seems to have quite tight operating parameters which it considers "normal".

The prototype was tested and produced the existing dyno chart. Richard has not mentioned any CEL's with the prototype intake manifold. I'm sure he will confirm this one way or another.

going supercharged. i wont be needing this anymore. still hope all works ouyt well though

[richardholdener]

If you are running the Blitz/Greddy then the intake/supercharger combo replace the factory intake. If you are going the Rotrex route, this intake will offer sizable power gains on that application.

I just don't see any reason for the intake to be more than a few hundred dollars. Any of my V8's from Edlebrock cost around $300 to $400, brand new. Granted these were produced on a mass scale, but, it's only a casting issue. Just my .02

[richardholdener]

This is an economy of scale question. To produce a casting requires a substantial initail investement in tooling and molds ($30-40,000 for a simple one), then castings and machining cost are dependant on the number of articles produced (the greater the production run the lower the per unit cost). naturally we will not be casting an intake for the Yaris market as we doubt intake sales will justify the investment of $50,000. This means we have to run small production runs of a hand-fabricated (some CNC work) intake-the end result is a more expensive per unit cost.

don't know if I'm reading it right but the low end is really low compared to "stock."

The area under the curve for the intake manifold looks to be much lower than that of stock so wouldn't that be of less benefit or something.
Not trying to bash the manifold but I was thinking it would increase the numbers along the whole rpm range.

[richardholdener]

You are reading the graph incorrectly. As indicated by the power curve, the new intake offers better power at every rpm than the stock manifold, from below 2500 rpm to 6500 rpm. Though the most prominent gains come past 5000 rpm, the new intake does offer gains of 4-5 lbs. ft. at 3500rpm and 5-6 lbs. ft. at 4000 rpm.

so rotrex is making a sc?

[cali yaris]

"The Rotrex route"... ? need more info!

[richardholdener]

I am not providing any new information-I just thought the PE blower kit used a Rotrex. The point is that a centrifugal supercharger systems still uses the stock or my intake and that this blow-thru system will benefit from the intake upgrade.

Everyones ears just perked up and did a Scooby, lol

[at3GG]

You can't use the blitz with this IM as it (the Blitz kit) replace the intake and manifold. It seems to me that if this with a full exhaust is making 120whp, so say maybe 125 with the pulley set...why exactly would you spend the $3400 on the blitz, when that only make 130ish? 700-intake-200 good CAI 700ish for full exhaust 250? for pullies....1850 compared to 3400.....plus no warranty issues....plus the ability to use a "rotrex style" SC eventually or turbo? seems a simple choice to me

[baked_limabeans]

sweet. Looking at it again, i realized that i was looking at it wrong. I'm an idiot. I wonder if i'll change classes in autox if i get this...

EDIT: been reading the solo rules and it will change my classing.

lol not trying to bash, but youre funny as hell dude, what constitutes it need to be made of aluminum... if someone has a sheet of stainless steel and welded up an intake manifold would it not work? right... i mean hell, even if the thing was made of fiberglass it could essentially work....

fiberglass would be ok but we already have plastic one unless the could mold a nice one out of carbon fiber. about the aluminium i would have thought that it would dissapate heat better than stainless.

i think its like a 50/50 thing because of brake lines and exhausts and junk are made from stainless steel, but i think any metal would work... as long as it doesnt melt
