Char's E92 Build thread

[MexicoCityM3]

Turbo guys? Really? With that dyno?

[Submariner]

Nooooooooooooooooooooooo!!!!!

[Char]

Nooooooooooooooooooooooo!!!!!

Another sticky note.

N/A 250 crank hp.

Z4 3.0si?

Char is right.

There is a y-junction/pipe and then the pipe splits to feed into two separate mufflers. Char's kick-ass stainless steel y-pipe (KASSY) would be at this split.

TSXs don't have a true dual system, it just splits at the muffler.

That's not what this is, it's (hopefully) a true single from the exhaust manifolds back. Lighter weight, better exhaust gas scavenging., more power.

Char was envisioning a GTI-like system with a single pipe + single muffler that simply has two exhaust outlets (and hence, no opportunity to use his KASSY, unless he goes with an aftermarket system):



Aftermarket GTI exhaust system (KASSY compatible):



FYI I really really don't recommend getting in the middle here.

Did you see the original TSX picture I posted?

You posted no such pic, but you posting a pic that proves yourself wrong does not help your wrongness. Take your wrongess like a man and carry on with your "build" thread, KASSY and all.

Exactly, your KASSY would to right at the y-junction (though that system looks to have a flange rather than weld).

With but ~215 hp he's setting himself up for a massive eating of crow. It's gonna be brutal.

[12,000 RPM]

Looks like an M50 curve

I think, and said, N52 in the past. I believe in another thread he confirmed as much.

That the lil homie has to go to such lengths to hold people's attention is downright depressing.

[Eye of the Tiger]

I think it looks more like an L38 engine.

You guys are literally getting worked up over me, the biggest troll on the board. You're not as clever as you believe -  I'm not playing your game, you're playing mine.

Cry more.

You are on some HEAVY drugs. Why would anyone tune a Y pipe for a turbocharged application?

The 944 has the Computer Assisted Shift Indicator System (CASIS). It's a glorified shift light, but I call it Cassy.

But, looking at that torqie curve, it is obviously with a turbo with a Y-pipe.

[Secret Chimp]

obviously you just take old-fashioned donuts and run your intercooler lines through there so your intake air is icy

Why would anyone "tune" a Y pipe for any application?

dat '80's tech

[hotrodalex]

Other than tube diameter and maybe angle of the Y, what could you possibly even tune.

[12,000 RPM]

Yea most y pipes, especially at the back end of the exhaust, are not tuned.

And in any case, not sure why anyone would tune an exhaust- Cougs has said repeatedly that OEMs never leave any power on the table

[GoCougs]

Only complete exhaust systems are "tuned."

[AutobahnSHO]

Only complete exhaust systems are "tuned."

By improving one section it would totally be possible to get a better "tune"..

[GoCougs]

Generally no. Plus, by definition only "improving" one section is not tuning.

An exhaust is only as good as the worst part.

[GoCougs]

An exhaust is only as good as the worst part.

There's no such thing as a "worst part" on any modern exhaust system.

[SVT666]

There is ALWAYS such thing as a "worst part".  Especially if it's GM.

Well the worst part on any new car is probably the catalytic converter...
