Official Richard Holdener *MID-RANGE* Intake Manifold List

[WolfWings]

$699, only sign up if you want the *MID-RANGE* intake. This won't happen unless we get 10 people interested. Want max performance above 4000rpm up to redline instead? Go sign up for the top-end manifold, same price, all top-end power! (http://www.yarisworld.com/forums/showthread.php?t=9915) The mid-range intake really doesn't have any advantage once you get over 55mph and out of 2nd gear.

Also, if you're signed up for the top-end model already, I won't let anyone swap over to this list as a confirmed sign-up as that could reduce the top-end list below the 10-count they need (and reached legit before I started this list!) to get the top-end model produced. I'll have to decline any more switches unless they can find someone to take their place on the top-end list and have that swap CONFIRMED.

I'll link to your post where you say you're interested in the mid-range. Also, I'll update this at least once a day, but I work odd hours.

I'm very interested, but also very broke. :frown:
I'll let you guys know if can can commit soon enough.

[Klink10]

Yes I am interested, yes I did already commit. Yes, I am also waiting for the dyno charts to compare, but i will follow through either way.

And NO I'm not a YES man......lol

[mikenacarato]

whens the deadline? If i have some time before this ends i will go ahead and commit. is this manifold a direct bolt on and can work with all factory things? i was going to get an intake and exhaust first but i would rather take this opportunity on this manifold. as long as i have time to save im in.

[bdc87]

I'm on the list for the top end but would much rather have the mid.

Deadline is unknown at this time, if we can get 10 for the mid-range it gets made. Otherwise only the top-end-focussed intake gets made (which already has the 10 minimum people signed up) and they'll cost the same either way.

It's a direct bolt-on, yes. No fabrication work needed. And it works with no Check Engine Lights, just swap-and-enjoy. It does benefit from additional work like exhaust and swapping the throttle body for a larger one (details will get re-posted eventually, they got lost when the site was hacked sadly).

traitor! what, you not a "racer" like us!? haha :burnrubber:

[mikenacarato]

well in a drag isnt it the torque that wins races?? ;) so are these mid range even giving more torque.

also, add me to the list, im in fo sho

[PETERPOOP]

actually i heard it's the high end that you want for the 1/4 mile. was i mistaken? there was a discussion on this before along time ago before the hack. R.I.P. so i might have read it wrong! doh

Because the torque gets you to your ultimate power of the engine in the high rpms. If you are "racing" you should be shifting at like 6000rpms. Then the rpms would drop to like 4000rpm after every shift? So it's constantly in the high rpms. Only the initial start from the line is when you wish you had the mid range mani?

However you might be right. I would think with the low end torque from the mid range manifold working together with the turbo lag would be the best combination? wouldn't the mid range get you to spool faster?


someone clarify this because if the mid range is what i'm looking for, i need to switch lists and be a traitor. i'm looking for best 1/4 mile time. and i am planning on going turbo in the near future. do i need mid range? or do I need high end?

[mikenacarato]

ya it can help some, what REALLY helps is port and polishing the turbo inlet. i got my gt2871r on my volvo to spool 500rpm faster that way.

[ChinoCharles]

In a drag race, you spend most of your time above 4,000 RPM... so no, that logic wouldn't hold true. Nice try, though! :wink:

[PETERPOOP]

that's what I was thinking

[kou]

dont hold me to this but i am pretty sure the mid range manifold falls flat on its face at higher rpms.so you may get a jump down low but you will get a nice look at my yaris as i pull past. i personally dont mind revving the motor.

[PETERPOOP]

exactly, it'll be like the high end manifold has a lag to it, but once it reaches the 4000rpm mark. SEE YA!

[ChinoCharles]

Guys, I don't want to crap in your thread, but I'll say it once for the sake of arguing. I think this thing is a waste of money. If you want track performance, buy they other one. If you want daily driving performance, stop modding your damn car. Take your $700 and buy a scooter.

[kou]

i dont think you will notice the lag but you will notice a power jump.ther is no hp loss in the lower rpms and there is some jabs o tourqe 2500,3500rpm and that is an a stock yaris.

[mikenacarato]

well i would stop modding the yaris and get a bike but i have 2 problems, 1 i havent even received the yaris yet, and 2 i already have a bike! ;)

[PETERPOOP]

i dont think you will notice the lag but you will notice a power jump.ther is no hp loss in the lower rpms and there is some jabs o tourqe 2500,3500rpm and that is an a stock yaris.

oh yah. i definately know what you mean. i was just making a bad example. i was just saying in the terms of, it will seem stock until BAM 4000rpms!


and yah i don't understand why the non "racers" want the mid range. So you can zoom to the street lights faster?

[WolfWings]

Flat-out, Chino is right. If you're racing anywhere raw top speed matters? Go get the top-end manifold. Don't waste yours or Richards or my time signing up here for the mid-range. The mid-range intake is (at best) useful if you're playing around in areas where your speed will vary between 20-55mph constantly so you can avoid downshifting to 1st all the time and your RPM's simply can't be guaranteed to stay high enough to benefit from the top-end intake.

Once again, it has nothing to offer at the top-end compared to the top-end-optimized intake. And again, at best this can be thought of as useful for playing around in overly-tight canyon's or extremely twisty courses in parking lots. My use and situation is far more specific than the general 'more peak performance please!' group that the vast majority can happilly fall under.

Not drag racing.

Not 1/4 miles.

Not stoplight-challenges.

Not actual track days.

If you're looking for any of those? Go grab the top-end version. Yes, I'm honest that my prefered intake may not get made, but I want everyone to be happy with what they get rather than make people unhappy just so I can get my relatively custom-purpose part cheaper. I'm a niche, I'm hoping there's enough to justify a production-run for the niche I'm in, but I'm okay if it turns out there's not enough to justify it.

[mikenacarato]

im still in for this one

[kou]

i hope they both get made.:thumbsup:

[Yoda]

interested but strapped for cash right now lookin into December before i have the funds. I am not racing my car i just want a more peppy feel to it thats why i opt for this one. there is no where in my town that i can really open up the engine to rev up past 4k and then wat... slow down so i dont get pulled over. pff
I am not taking my car so i can race honda fits or any of that mess. When i step on the gas i want to feel it without my car roaring past 5k for the whole world to hear. All these mods i am doing is to suit MY driving style and for MY enjoyment. those that feel that this intake will suit them best jump on it so we can get it made :)

P.S too lazy to punctuate.

[cali yaris]

so, some people are switching if TEN want the mid-range version?

After Richard is in the production cycle for the top end version for at least ten?

What if there aren't ten people left for the top end version then?
Isn't that a little out of integrity for our commitment to the producer?

Just trying to make sense of it -- help me out.

I'm monitoring both lists. So far there's 13 signed up for the top-end model, 2 of which may switch to the mid-range model. One more could switch without impacting the 10-count for the top-end model. If any more try to switch, they'll have to find someone to take their slot on the top-end model before I'll add them to the mid-range model, unless Richard wants me to handle it some other way. That's also why I put big, massive red flags saying who was also signed up for the top-end model and may switch. As I said just above, I'd rather my model not get made than screw anyone over.

I'll update my first post with this information so it's more obvious I'm really not wanting to screw over Richard or anyone else here. He said to make a list of those interested in the mid-range model, so I am. (http://www.yarisworld.com/forums/showpost.php?p=164475&postcount=179) :-)

[PETERPOOP]

yah. kinda lame if the guys bail out on the top end. but I guess richard will have to sort this mess out.

for the record, i'm still on the high end! heck yah!

[pinoypizzaboy]

I just hope Richard doesn't stop production because of switchers. I also want this manifold but already signed up for the other 1. Cmon now guys

[ZING]

The top end doesnt work on the 1.3L, does this one?

[bdc87]

Well I would need to see the two dynos before I've made my mind up, could we get that?

[PETERPOOP]

I just hope Richard doesn't stop production because of switchers. I also want this manifold but already signed up for the other 1. Cmon now guys

i highly doubt he'll stop production of the high end. that is what was decided first. even if the two guys bail, we'd have 11 people on the high end list. and i am sure there are 2 other people out there that would want the extra two if they were to be made.

[kou]

i will :burnrubber: on your midrange.

[LtNoogie]

I think that once you guys get your high-end intakes in AND dyno your cars for proof, none of this "it feels more powerful" stuff, more lurkers will come forward asking if they can buy one.

[PETERPOOP]

well they continue to be lurkers because i ain't paying no money for a dyno! i will FEEL the power! muaha

[kou]

video is probally all you will get from me.

[cali yaris]

The top end doesnt work on the 1.3L, does this one?

No - it's almost exactly the same design.

[CASTREX]

No - it's almost exactly the same design.


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.

[cali yaris]

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

[Klink10]

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.?

[cali yaris]

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.

[Gideon]

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?

[PETERPOOP]

I am being sarcastic, I want to see his dyno chart, must be his dyno chart the other dyno charts are not the same must be peterpoops.:bellyroll:

I realized your car is a sedan. LoL.

[LtNoogie]

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!"

:wink:

[kou]

Did not put the compressor in there to make it a race car just to give it the boost it needs. I do not race, I lost my license for 5 years for doing that, well a little more complicated than that but it was revoked for racing. This car seriously lacks any kind of power from the factory. Should have come from the factory with about 150 hp.

+1 on the horse power i will be happy for a while with an extra 15hp to the wheels on top of what i already have.until turbo.

[bdc87]

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.

4dr FTW!!!!!!!!!!!!11

[bzinn 1]

well in a drag isnt it the torque that wins races?? ;) so are these mid range even giving more torque.

also, add me to the list, im in fo sho

To sum it up from an old school 1/4miler.....torque gets you from A to B as quickly as possible.HP.......makes the tires smoke real pretty.......

The guy who said that goes over 320mph in the 1/4.

ehh sorry to tell you buddy but its the torque that makes you tires smoke real pretty. really dont feel like typing out a long explanation just look it up. alot of people confuse the relationship between the two

[ZING]

No - it's almost exactly the same design.


Didn't get my hopes up hehe.

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

[mikenacarato]

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

[anonymous user]

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.

[anonymous user]

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.

[PETERPOOP]

:iono:

[Yoda]

lol its hard to wrap your head around. Just think of it as that sinking feeling you get in your car when you floor it at around 4k rpm or where ever it hits its peak tq. Thats where you will feel the tq the most.

Also look at a water wheel. Its does not spin really fast but it generates a hell of alot of tq

[mikenacarato]

well i hate to say it but due to lack of interest i am signing up for the high end list. i dont want to miss my chance to get a manifold.

[WolfWings]

No worries, and like Richard said if you just want max performance the top-end one is honestly better. Richard knows what he's talking about, I'm in effect requesting a custom tune of this intake optimized for 2nd-gear 20mph-45mph usage, while still being usable up to 55mph before it fizzles out. I.E. Around 2000rpm-4500rpm, and still at 80-90% of stock up to 5500rpm, it can fall on it's face sharply at that point and I'd be pleased as peach since it'd suit my desires flawlessly then, which is parking-lot autocross.

In any case, nipped ya' off the list as requested. Good luck, Mike. :-)
