diegohiga celica progress, 3rd gen 3sgte, jdm mirrors, quick release steeringwheel installed. Options

Diegoooooo !!!! If u need a non turbo fuel pump from supra there is like 4 down here in Miami I can find u one unless u need a new one or something

first i need someone here on the forum to confirm this info is right. and yeah i would get a new one. had issues before with fuel pump not working because they get old and it sucks haha

[diegohiga]

do i need a gt4 trottle cable or gt one works fine? because i realized that the cable goes around the valve cover an seems much longer than the gt or st cable

[Batman722]

GT is fine.

[diegohiga]

today i got a couple packages albro
APEXI n1 muffler
megan racing 2 core radiator
QTP exhaust electic cutout 3"'
Walbro fuel pump




try to take a pic measuring the outlet but came out blurry. inlet is 3' and oulet 4.5'

I was searching around and found this topic: http://www.6gc.net/forums/index.php?showto...ss-iii+trd+rear

It's come along really well.

[enderswift]

I like your exhaust cut out. You have good taste

wowww thats old haha i had different ideas back then, that front bumer was pretty ugly now that i see it hahaa

thanks

That'll look real nice.
Whats the "exhaust cutout" ?

[richee3]

It's a butterfly valve to bypass the majority of the exhaust for more power when he chooses, when he gets the 3S swapped in.

[Ted95]

The cutout is a great option for instant power without further adjusting your boost controller. I'm running 14psi with my cutout closed and jumps up to 17psi with the cutout open and sounds great!

Thats what I though.
So, electronically controlled, you can let more exhaust flow for more power?

Yep, basically you put it before anything ideally (cats, resonators, mufflers) to simulate an open downpipe.

You can also do it with a throttle body. My previous Celica had it done with a 60mm TB on 2.25" exhaust tubing. The difference is it's manual vs electronic. I plan on doing it again to my actual Celica, and it'll be manual again. There's no motor that can go bad that way.

This would only be beneficial to a Forced induction motor, correct?
Would that not cause a decrease in back pressure on a n/a, resulting in a loss of power? (if used in the exhaust)

Depends on the location and application. Think of it as an alternative, not an upgrade. Instead of getting a noisy exhaust, you can bypass your stock muffler with upgraded exhaust tubing up until the cutout, then scale down to stock for quietness.

In a Forced Induction setup you could use it as an exhaust bypass, which would mean better spool, for example.

Yall are silly. The real reason you spend hundreds of $s on exhaust cutouts if for the sound. The car goes from quiet like grandma's grocery getter to open headers racecar pitstop in a few seconds.

And backpressure on any engine is bad, its high velocity flow which is good for a N/A.

That's the only reason why it was on my previous Celica...

Go put 3" exhaust, from header back on your n/a, and let me know how that works out for you.

Backpressure is bad. NA engines need high velocity exhaust flow. Narrow piping generates more backpressure than wider piping, but it also speeds up the exhaust gas velocity.

So it's not really backpressure what you want, it's exhaust velocity.

Hotter air also flows faster, which is one of the reasons why things are thermal-wrapped and coated. They help keep the heat in which in turn speeds up exhaust gas velocity.

What backpressure means in an engine is that the exhaust gases are being restricted or prevented from exiting the combustion chamber. If backpressure was good, clogged cats wouldn't be bad, as they generate immense amouns of backpressure.
