106 HP = stock engine
11 HP = plus wr intake
3 HP = ram air kit (took that from their dyno with their XB)
5 HP = plus MR Headers (HOPING for at least that much gain...)
7 HP = plus full 2.25 catback exhaust (with the headers, i hope i get that much gain!)
1 HP = ground kit (heard it will give u very lil gain)
____
130 HP???

103 TQ = stock engine
10 TQ = wr intake
1 TQ = headers (dunno if it will produce my tq)
1 TQ = exhaust (same with this)
____
115 TQ???

is this sorta correct?
haha supercharger = 170-180 HP???

[YarisPR]

go to a DYNO and run it and see if all the mod where worthy :evil:

[dngz]

dunno where to dyno in vancouver =\... how much does it cost to dyno?

[ChinoCharles]

It is 65 bucks for three runs or a half an hour up the street from me. You can't just buy one run. My first trip will be as soon as the Megan headers arrive.

dngz, that may be a little conservative. For example, when you get a cold air intake it will raise the gains on all of your other parts by a small percentage, at least in theory.

[dngz]

yea but in actuallity, dyno will measure whp, not engine hp. ill be happy if the yaris will get 100 whp!

[dngz]

chino did u pay for the headers gb?!

[eco]

Chino said he would pay Monday.And the cooler the engine,the more horsepower you get to the FW's.

[bigsky2]

Das right... colder engine = better performance
Just like PC's, you want your engine (processing unit) to be cool so you can take it to the limit.

So if you want to feel really good, look for a tuner shop on Burnaby mountain or up in Squamish/Whistler. Your dyno runs will look freaking awesome! Higher elevations = colder!

Just be prepared for the shittier performance on paper and the road when you reach Vancouver again :laugh:

[Yarii]

Higher elevations = lower air pressure, less oxygen getting into the engine. I'd be surprised if the colder air gave you an advantage over the power loss from lower oxygen.

We obviously are talking HP at the crank. And stop harassing me.

[mikeukrainetz]

In Van there shouldnt be too much of a diff. with the elevation change, plus some of these new cars compensate for elevation change, whether the Yaris does or not I dont know.
With all the mods listed you should be gaining a real noticeable difference regardless.

[YarisPR]

Just dyno it ... dynos do give you WHP and HP :biggrin: and a lot of other information knowing WHP isn't everything you want to know of a car. there's more than that. :thumbsup: I'am a lucky guy there are like 10 dynos here in Puerto Rico and none of the at more than 2 hour... i love this island.

And Yes cold air places make better dyno runs.... but not at high altitudes...
Ex. Here we are drag racing fanatics and we hold some records in the 1/4 because we test and race here (Tropic = hot ). But when we hit the US times go down because our cars run much better :thumbsup: and sorry guys but..... usually when we go there is to beat some a$$ :evil:

[spkrman]

dyno before and after :)

100+ to the wheels would be a good goal, I'd say.

[Katana]

+1 from me.

I think the loss is at about 20%.

[ProMotionTuning]

Just remember, you cant just add up the numbers per part! It definitely dont work like that. We have a AWD Dynojet Inhouse and see so many peoples feelings get hurt when they get on the Dyno.... Most Manual transmissions have a 15% Drivetrain loss so expect that for every 100hp your engine puts to the crank, you are only getting 85 to the wheels.

He said it all :thumbsup: Just don't be taken by surprise

[dngz]

so what's a good goal? i have manual transmission..

[ProMotionTuning]

If you have intake, header and exhaust.... 100whp sounds great to start as a small goal and if you walk out with 110, you are happy. I personally have not dyno'd a Yaris yet stock or with any mods to see the power curve to see where it can approve. At this time I think Leo at WR has and shown good gains.. but I would personally like to do one here in VA at Sea Level before I get anyones hopes up! Bare in mind... Dynos are stationary so unless there is alot of air moving (by fans), your ram air kit isnt going to do anything on a dyno.

the wr intake dynoed with increase of 10 TQ and 11 HP without moving air (i think, according to the vid) so, either way, not too shabby!

[boris13]

I'm curious about what the characteristics of a Weapon-R type (short) intake might be vs. the characteristics of a longer intake like the AEM or the TRD. Which type of intake is going to give me better low-end torque and will not hurt my mpg? I would love to go with a more efficient intake for better everyday drivability, and more power is certainly OK, but I don't want to sacrifice much in fuel economy.

Thoughts?

[ChinoCharles]

Boris brings up a good point. If you're serious about the life of your car, you shouldn't be buying products based on the amount of hp/torque you gain alone. There are more important factors to consider.

This is why I lean so hard towards the TRD intake. If Toyota would put their seal of approval on it, it obviously must be built to work in conjunction with the 1NZ-FE to provide stable, reliable power. Notice the piping length is inbetween the AEM and WR versions. Its a happy medium.

I am going to try and work with the guys at The Race Car Factory here in Ohio to get a viable american-made TRD intake replica. However, I need to show them that there is enough interest in the aftermarket to warrant the development of a part like this, so if you want to help go check out this thread.

Let us know what you as an American consumer would like to see for the Yaris, and I'll pass the good word along.

The Race Car Factory is an awesome company, and they aren't one of those that hopped on board after the F&F came out. They've been in the business for 30 years. They develop superchargers and do R&D for the likes of Greddy and Vortech, and also are involved in NHRA/IHRA... one of those true "we can do anything" speed shops. I talked the guys ear off about this forum, this community, and our car, and I think he sensed my excitement. So like I said, let us know what you want to see.

When I toured the shop yesterday, they had some amazing projects. The one that caught my attention was a motorcycle that got a rear axle to convert it to a trike. They then stretched the chassis about 5 feet, had a chopped Ford Model A body waiting to be mounted up to it, and sitting next to it was an 800 hp Ford V8 that was awaiting install. That was one of the most unique projects I've ever seen.

They also had a 3000 hp funny car that just got back from a drag featured on ESPN. All in all there was about 12,000 HP in the room and only 12 cars, ranging from two Dodge Darts to a Datsun with a heavily-modded 4G63 to a brand new RX-8 that was putting 400 hp to the rear wheels with the help of the Greddy e-manager, which RCF helped develop. I left with quite the horsepower woodie.

Excellent point, ChinoCharles. Toyota tests and certifies 'performance' products to keep reliability within a certain parameter; i.e., engine life. They then give these 'specs' to companies that already make these products to 'private brand' them. To that end, the company you site could produce products that meet these requirements (clone them) at a much more competive price. I'd be very interested in an intake, sway bars, braces as these are the easiest to produce.

[Doc Zaius]

how come the CAI isn't listed on TRD Japan's offerings for the Vitz? http://trdparts.jp/english/list_new-vitz.html they only have the sports air filter which fits into the stock air box. it seems there are not nearly as many japanese companies offering CAIs as compared to their north american counterparts. why is that?

[dngz]

how much life would a supercharger take away from this lil engine that could?
