1 foot exhuast? would it harm the turbo?

[twin_turbo_mk3]

okay so another question ihave is will running ONLY 1 foot of 3" exhuast from turbo elbow hurt the turbo?

after reasearch im finding that turbo does not need back presure so ifigure it wouldnt? or would it?

You really don't want all that heat/fire in your engine bay. At the very least run a full DP.

Yeah you will start cooking stuff and then its not pretty....

But, to answer your original question, no it will not hurt your turbo...

 

[grimreaper]

wasnt there a few guys that caught there car on fire with open down pipes?

 

[Rennat]

yeah, well at least he blamed it on the open DP...
tranny fluid leak + hot exhaust gases = no more supra

dont do it, its not at cool as you might think, if you do do that, go to an exhaust shop and buy some pipes for $20 and put it to the outside of the car or something.

I heard a story where a turbo golf IIRC caught on fire because he was dumping and it was hitting some heat shield on the firewall...

Theres a vid of it on youtube on fire...

Yea, that video pretty much sums up a fear of mine: my car bursting into flames.

I vote for at least a side exit or something/anything other than a 1' dump.

 

[sportinct26]

what if it dumps directly under? so it wont hit anything but the ground under?
i was planning on running a cutout that exit under.(ofcource its longer than 1') would it still be risky?

Its not a good idea to dump that much heat under the car at all let alone you will be breathing exhaust when you are sitting still *also not a good idea lol*

You can though run a downpipe all the way to the back of the car which would be loud as shit but hey cheap and effective...

 

[mk3tattoos]

it does not sound like a good plan!

 

[Bigdough666]

If you plan to drive this car on the street at all, you will NOT want this setup. I ran open DP for about a month and it was terrible. Too loud, got weird looks and the wrong attention (READ - COPS!!!!), got headaches from the exhaust fumes, crazy resonation, etc, etc, etc. It was cool for a couple days, then it got bad. I never had any experience with fire but a friend of mine was parked on the side of the road one time idleing and set the median on fire, so Im sure if you had any kind of leak, it could easily catch fire. Do yourself a favor and at least run straight piping to the back of the car.

I had a friend that was running a similar setup on a civic with a h22 ( prelude engine ) + huge turbo + nitruos ( 1/4 mile setup ) we made a custom 3" down pipe that exited right after the front wheel.

We swapt the pipe every time we went on the drag strip newer on th street cus it was a reel flame thrower.

 

[sportinct26]

so whats the difference bitween under the car test pipe/cutout. and straight vent? or is it the same hazard?

so in point whats the point of electric cutout if its that risky?

btw with the side vent wouldnt the passenger be suffering lol

Depends on where the side vent comes out...

A electric cutout is ok, but honestly if you want an open sound just run a straight pipe man...

That's terrible advice. An electric cutout is an excellent idea for a street car. People with straight pipes annoy me and I tell them so.

 

[CATarga]

Even without starting a fire anytime the exhaust exist in front of or under the passenger compartment you are going to be inhaling exhaust fumes whether you are on the highway or sitting still, and if you have the windows up you will be tits up on a long drive.

As mentioned just run a an open pipe the back of the car, or if it is street/strip run an electric cut-out attached to a pipe the exits the side or rear of the car if you plan to use it on the street.

^^ doesnt that mean that a ddp would be a "bad" idea since it vents in the engine bay

 

[Poodles]

DDP isn't always open, and it's vented straight down, not parallel with the bottom of the car.

Not a fan of cut-outs personally, as getting a good flowing and great sounding exhaust beats it ...

 

[grimreaper]

ive owned 3 electric ones, all leaked at the butterfly valve at some point (VERY annoying) as the motor lost its ability to hold the seal with heat/exhaust pressure.

well with the cut out that i was thinking it would vent straight down. and to be honest i like the sound of open dp.
