I don't know what post that's from but on my Echo it is indeed 6500rpm. It's different between models.

So after close to 1400 posts I guess my question is what does this intake actually gain someone? if HP/TQ are negligible are we talking an FE gain at this point? I apologize, but with this many posts even digging back on a couple hundred can be muddled.

Just these modest gains and about 2mpg. That's it. It's not a miracle product, just an intake manifold that allows running a larger throttle body. It's primary advantage is excellent throttle response and some improved fuel economy without ruining the reliability of the engine.

If you want lots of power you need to buy a forced induction system. Keep your eyes open for a used one. A lot of them end up being resold.

No problem.

You have your complete answer in just this one post.

The PR spec cars might be. The PR spec '03 HB I drove a long time ago had a 6700 redline.

fnkngrv · 08-26-2013, 03:56 AM

^ very good and valid point! I had forgotten that.

cali yaris · 08-26-2013, 12:36 PM

I'll test and video JR's car today. We should be able to hear the fuel cut at 6250... or 6500.. or 6700...

xnamerxx · 08-26-2013, 12:50 PM

I'm pretty sure the rev limit is 6250, That's the only number that's ever corresponded with my data. 60 MPH in 2nd gear is all I've ever seen with my race tires.

Kaotic Lazagna · 08-26-2013, 12:51 PM

lol, sorry guys, couldn't resist with the talk about the redline. hahahaha

Kaotic Lazagna · 08-26-2013, 02:25 PM

If I were still modding my sedan, I'd probably go with the Tooter and the 1ZZ TB based on the torque curve in that dyno graph (I do most of my driving from 2k-3.5k).

doesn't that dyno show it making whatever power it makes at 3500 and up?

green line?

Yeah, green line. I kinda disregarded anything past 4k as I'm rarely ever past 4k unless merging on the freeway. lol. Any bump in torque below 3.5k is a plus, but I do see that it does lose some torque around 2.1k.

The torque curve dips below stock at 2,200rpm and peaks above stock an equal amount at 2,400rpm. I'm sure it's because the manifold isn't specifically tuned to the engine, so it has an uneven curve. And that's at wide open throttle, under normal partial throttle driving conditions that extreme effect is not felt.

I posted the dyno runs warts and all and let the chips fall where they may so that everyone here can see for themselves and decide for themselves because its dishonest to make claims without providing any proof of them.

It's not like I'll be at 2.2k rpm for very long

I'm sure with the Tooter, SRI, 1ZZ TB, a header, and a 2" cat-back exhaust, it'll have a nice low end torque increase over stock

Here's a youtube video of the tooter et dyno run...

Pretty cool!

cali yaris · 09-04-2013, 01:20 PM

This netted 2hp and 2 torque, a 1.5% gain. Easy mod to install, not too bad.

1.5% on a Yaris would be about 1-1.3 hp I think if it were proportional?

tooter · 09-05-2013, 02:21 AM

You missed the point, Garm...

It doesn't make gains. It moves the torque curve lower in rpms. The stock Tacoma 2.7 engine's torque peaks at 3,800 rpm. With an LCE long tube header and this intake manifold spacer, the torque peak is reached at just 2,900 rpm... without reducing the peak value.

The speed limiter cut the engine off on those 4th gear runs, but it didn't matter as it was just to get the low end torque readings.
