Roostfactor’s Equal Length Y-Pipe

That's fine. My warranty doesn't end until October anyway haha. I sent you a PM last night. I've spent the better part of this year patiently waiting on swaybars that I already paid for so I can easily handle a month or 2.

Thanks @Roostfactor !

 

@TitanRattler813
I thought I would fill you in on what I have done to my truck. Others have done similar and it's not an all inclusive list but I am around 375whp.

76mm Tundra tb. Modify the butterfly adjustment so you dont get high idle
URD tb adapter
Magnuson sc with STOCK Tacoma tune! Thanks @loginfailed
2.5 quick change pulley thanks @12TRDTacoma
My belt wrap mod
Ported sc inlet and outlet
Ported lower intake manifold (I may offer this service)
URD 61lb injectors and adapters
UCON
URD Walbro 255 pump kit
URD spec u headers (ported outlet flange)
My y-pipe
URD Mark III exhaust with

$125 Vibrant 1142 3" Ultra Quiet Resonator

Vibrant 1142 resonator
160° thermostat thanks @Torspd
CSF performance radiator
Davtron intercooler inlet and outlet temp sensor
Airaid intake

I'm sure I have more I'm forgetting but ask away here or in the supercharger tips and tricks thread. There is a lot of info there to keep you reading for days.

Cheers,

Roost

P.S. I just hit my 1/4 mile post!

 

The struggle huh. Hahaha.

 

I try.

 

Regarding the “smelly”... After installing the URD headers, I’m wondering if I’ll mitigate the noxious cloud I’ve been creating when I get my UCON programmed and installed.

Think it will clean up the burn, especially at idle? This is the first cat deleted vehicle I’ve had that is so smelly.
No hippy.

 

Idle is closed loop whether UCON or any other tune so you are at stoichiometric af ratio of 14.7.
Nothing you can do to get rid of the smell except for installing a cat.

 

So the air/fuel ratio that’s factory set for SLP (during idle) can never be adjusted? Are there other closed loop scenarios that can be affected by tuning/tuners/calibrators?

 

When I saw this, I immediately thought "kinetic" pipe. Best looking any exhaust I've ever seen.

 

@TitanRattler813 sorry man. Xru is just dead and boring. I guess all the xrunner guys are on Facebook. I’m always on tacoworld now. Guys on here are all awesome and love the info

 

Thank you!!!

 

SLP?

 

Assumed 14.7 refers to Sea Level Pressure.

 

14.7 parts air to 1 part fuel.
Atmospheric pressure is irrelevant in this case.
Look up stoichiometric ratio for more info.

 

Do you mean MSL (mean sea level)?

 

Maybe DSL?

 

All the same sort of. Mean sea level pressure, average sea level pressure, 1013.2 hecopascals, 29.92 in mercury at 15 degrees Celsius, 14.7psi.
Not really important, just how I interpreted the stoichiometric ratio when I saw 14.7.

When I looked up closed loop engine management on a hot rod forum the exact same number appeared. So I ussumed the only common variable between different engines for fuel mixtures at idle would be air density.

Just trying to understand why fuel ratio at idle, once the engine is warmed up is no longer adjustable via the UCON or another means. I’m surprised that regardless of NA or FI modifications it can’t be trimmed. I’d figure turbos and SCs would definitely require some idle adjustment.

I’ll keep reading....

Edit: I’m getting it now 14.7:1 ideal fuel (stoichiometric) burn for gasoline, 14.5 for diesel, etc. which is a lambda of 1.0.

Rather than clog up this thread with my follow-up question I’ll find another one in the performance forum...

 

True. It's nothing like it was 10 years ago. Just messing w/you. I honestly don't go on there that often. I've been more frequent lately because I'm checking for sway bar updates

 

And FB doesn't carry the navigational characteristics of a forum, as well as layers of detail. They should know better, but don't. Let's also not forget the camaraderie that comes with a forum.

 

By George, now he's got it!
