hidden turbo?

It must suck to live in Cali. Cops don't give crap about that over here.

Cali is awsome, its just the state gov i have a few issues with ha

It's happened to my friend's bottom mount. :p





but then the officer gave him a fucking REF ticket for the "cone" filter coming out from under the engine bay to the top.

My friend had to teach a cop what a turbo was and had to explain to him how his car doesn't have a turbo. Just headers and a factory airbox.
Stupid cops.

Kinda stupid but it would be the best feeling when a cop asks you to pop the bonnet expecting to find a turbo and finds nothing. Also I couldn't imagine how loud that setup would be with the dump pipe going straight to the exhaust tips. Wouldn't this also suffer from serious turbo lag.

any update anyone, i think there were a few people trying am i wrong?

[einstein57]

Gasses condense as the cool down meaning lower volume. Reduced volume means increased lag time. Thats why i suggested ceramic coating inner and outer exhaust plumbing from the manifold back. Guess you could also header wrap everything too for super overkill. The e30 just does not have the undercarriage room to run all the plumbing in the proper size. Maybe s 2.25 from the headers to a small turbo (8psi) and 2" intercooler plumbing to the intake.

im no expert...but dont you want the gasses to cool down before returning to the intake side of the motor?
so its like a double win?

No. Hot exhaust contains more energy to spin the turbine. The compressor side that pressurizes the intake side is completely isolated from the "hot side." As the exhuast gasses cool, they lose energy and potential to spin the turbine.

yeah i think it is too or its the e60 m5

Don't want to sound like I'm full anal about cars but is that an underside photo of an e92 m3?

[Rowanese]

i have never gone through any smog, visual test, or anything where i live in washington. and here in washington, after 25 years, no matter where you are there is no tests.

[devon.818]

the bigger issue imho is the energy lost as the gasses cool down whilst running through the system.

srs? ^^

I don't see why everyone thinks 10 feet of 2.5" tubing will cause a huge amount of turbo lag. When you consider how many cubic liters your car pumps out at just 3000rpm the couple of liters of air in the pipes are nothing. Its not like the exhaust plumbing in under vacuum. Its already pressureized from the moment you turn the key. Now the cats and mid pipes in the picture would hurt flow. I'd say a straight through, fully ceramic coated header back system should show minimal loss in response time.

i love the fact i can put a BIG ass top mount turbo on my car and not even have to pass any kind of sniffer test all they do is look at my car see it "has" a cat and then say it passed haha
