That's right. And even if it fits, you probably don't want this...

The manifold was designed and tuned for an SPECIFIC engine the 1.5L 1NZ

So, even if the manifold fits on the 1.3 (which I suspect it will) the performance of the unit on that engine is a complete unknown. It will be an expensive risk to take imho.

Didn't get my hopes up hehe.

My friend and his damn Rabbit mock me day in day out, must sabotage.

I don't know why the two dyno charts can't be re-posted -- they were up before.

If I remember correctly....Rich was still in the testing phase when the motor went tits up and was looking for a replacement to complete the testing with various other add-ons to come up with a for sure HP/torque figure to be posted here. We have now added another possibility in the mid-range version that would also need to be tested. If I'm wrong tell me, but last I saw testing wasn't finished so how could production of either model be going on.?

posted OCTOBER 28:

Congrats to the Yaris community-I will begin with fabrication of the production piece. When that first article is ready, I will arrange to have it tested with a member of the community and then go into production - hopefully intakes will ship by ends of Nov.

[Klink10]

Understood, and I saw it in Oct.

Quote: I will arrange to have it tested with a member of the community and then go into production.

This was the part I'm referring to.

Either way it's not important.....I made the commitment to whatever is made in the end.

If anyone would rather have the mid-range, I'd be more than happy to fill the higher range spot that opens. Just found out I'd be getting a bonus from work, so I have the cash. If not, is the requests still open for the higher rpm manifold?

COH dosen't look so good right now and work doesn't do any better I might have to give my spot up and I would surely give it to you.

And if I remember right. There are very little if any visual clues that a S/C is about to start wailing as the stealth Yaris sedan pulls away.

[PETERPOOP]

And the whining sound they hear while the car passes you and they think "is that yaris S/C? nahhh it's not even moving!"

the old phrase that was coined before i was even born is "horsepower sells cars, torque wins the races"

hey i didnt write the books lol, but this is besides the point. were all in here for the same reason...more power! :)

[at3GG]

from my understanding....

torque= low et's
hp =high trap speeds

Interested in mid-range version, but still undecided. BTW, i am on the high end list as well.

[tk-421]

Seeing both graphs side by side should clear things up quite a bit for all of us... I just hope Richard posts them soon!

[cali yaris]

Richard was at SEMA all week -- he'll be back with us soon.

Thanks wolfwings for adding me to the list. As stated by others, i do not want to step on anyones toes here. But if there are going to be 2 production manifolds, then i'd like to see the prototype graphs to compare the two.
And then make a decision as to which i like better.

[richardholdener]

To answer the horsepower and torque question, the two are matehmatically related (HP=TqxRPM/5252). Technically speaking, torque is force or work and horsepower is that work or force applied over time. Looking at any power graph from any engine ranging from your basic lawnmower to a 19,000-rpm F1motor, hp and tq output will always be equal at 5252 rpm. For any hp value-there is a correspending torque value. Torque values will always be higher than hp values below 5252 rpm (and vice versa). Hp does not do one thing and torque another since for any given amount of one you have a corresponding amount of the other. What most fancy quotes are trying to get across about HP & TQ is that low-speed torque helps accelerate the car and high-rpm horsepower creates higher top speeds. What really accelerates the vehicle is average power production over the engine speed used for acceleration-whether you illustrate that with HP or TQ values is immaterial. As posted on the other thread, I will be producing the high-hp version first and then if demand warrants, the mid-range version.
