Tooter manifold / Corolla TB / DC Header / etc....

I swapped the thermostat back to stock.

Sure enough the temps came way up (seems so weird to see temps in the 180 deg F range consistently)

The car behaves a bit better (the idle isn't as erratic) but otherwise its no faster or slower (feels the exact same)

Next step is to swap the TB and then the intake manifold.

Stay tuned.

Don't forget to disconnect the battery cable so that the ECU can relearn the new operating parameters with the stock thermostat.

And it has been disconnected since the install of the engine stuff as well (I've been working on the headlights and audio after doing the intake and TB, so I've had other occasion to disconnect the battery)

Its also worth mentioning that I don't have any seemingly bad side-effects other than a super high idle when the car is cold (first thing in the morning). Other than the high idle, everything seems "okay" (other than the fact that I think I've lost 10hp)

Looks like he already did. Wouldn't hurt to try again tho.

normal temps, same behavior -- thermostat eliminated as the cause.

is it done yet?

No

I've been swamped with other stuff and I've only driven the car twice in the last week and a half (let alone have time to work on it)

Right now its just sitting in the garage (where it is most of the time) waiting for some more investigation work.

Like I did with the Thermostat several weeks back..................I've taken this Friday off so that hopefully I can swap the Throttle body and then the Intake manifold and see whats going on.

I'm also thinking of maybe getting the exact header that Tooter has, and also installing my exhaust (have full exhaust just waiting to be installed). That way when I go and Dyno it, I should have a pretty good comparison against Tooter because I'd have almost the identical setup at that point (plus lighter wheels and a pulley's)

I'll of course update when I swap the T-Body etc.....

If you want an accurate apples to apples comparison, I'm not running a full exhaust, and only have a catback. Everything else between the catback and the header is all stock. I'd advise not making any more new changes, and backtracking to remove the 1ZZ throttle body and then the tooter intake manifold.

And if you're already running a DC header, I wouldn't waste any money on a Weapon R as they're both so short I don't believe that there is that much difference in performance between them.

It's tough tracking down the problem with so many changes all done at the same time. And if for any reason you're not totally satisfied with the manifold, please don't hesitate to return it clean and undamaged for an immediate full refund of your purchase price. I just raised my prices and will simply bead blast it again and resell it.

I didn't know you installed a midpipe section, tooter; or do you mean instead that you have an axle-back exhaust?

Just an axle back. I'm used to using my truck's terminology where there's no such thing as an axle back. Thanks for asking, Garm.

two different cars, two different dynos, two different days. Even with identical mods, they won't be comparable except in the most general way.

Of course

however

if I were to dyno 92whp (for example) with more mods that seem to compliment each other / and Tooter dyno'd 111whp ..............................................than , ...........that will prove what my butt says............................. which is that something is amiss.

However.............if I Dyno anywhere north of 100whp, than I'd chalk it up to a problem in my head (assuming I'm not able to find any other variables)

Hey trbo,

Haven't heard anything as to whether or not you got your engine running right yet. So what happened? If for any reason you're not satisfied with your tooter, please don't hesitate to return it for a full refund. Right now, I'm sold out so there's no problem taking it back to resell to someone else.

Please let me know...

(also pmed you)

^ I *wish* there were a flange there right after the cat for us to use!

Depending on the type of Dyno. I dyno'ed my stock yaris on a Dynamics dyno and got 115whp. Which was bogus. So I went to another shop who had a dynoJet. I got 87whp on that dyno. Dyno's are usualy on good to tune with, not to compare dyno numbers with other people who use different dyno's.

That's right in the ball park with the rest of the stock dyno runs:

87hp to 91hp

I chose Dyno Jet for all my dyno runs because their charts have really precise numerical resolution. A lot of the other dyno charts are way too vague and wishy washy and only indicate approximate results.

Will, did you swap the TB back to stock yet?

[Mz3oh5]

Looks better then my car ;)
I'll take your performance upgrade any day!!
