So ive done some searching, and i read all the opinions, and thoughts about exhaust brakes, and ive read how some people dont know the difference between jake brakes and exhaust brakes. Anyway i dont want any run arounds of how they work and how the back pressure can be excessive and blah blah blah.
And if some are wondering why i want an exhaust brake on a VW diesel, its because its in my samurai, and i want to tow a trailer with a quad and small boat in the near future. and besides we all know how cool it sounds.
Anyways finally my question, does anyone have some real world experience with putting an exhaust brake on a 1.6TD yet?

Jake brakes make the sound you want. Butterfly valve exhaust brakes just make a slight hissing noise, i doubt you'll be happy if all you want it for is the noise. Had one one a dodge 12v, worked great, very quiet.

yea jakes would be ideal, but ill take what i can get. Im glad your on the same page though, im tired of bringing it up with people and gettin the "but why". I mean really my brakes will probably put up with a trailer and then some, but come on how many people have an exhaust brake on a suzuki samurai, or any volkswagen diesel for that matter. Id love to be the one to try it out but after recently spending 3g on my engine i cant justify experiments. I think i need a cheap little jetta or something.
When i was workin on imports from japan, the little cabover things they had had exhaust brakes and you are right, they dont make quite the noise a jake does. But it definately had more of a rythym to it than a hiss.
Anyone ever manually override a jake brake and give it some throttle?? My instructor wasnt impressed when his ears were ringin and there was a 2 foot flame coming out the turbo haha, oh good times at school.

how are these engines going to handle the ADDED BACK PRESSURE? not gonna blow the gasket out of between the head and block is it?

I think it would be fine, it won't be firing with the gate closed anyways.

i think turbo spool up with added temperature is alot harder on it than the exhaust brake. and i have a mls gasket with arp studs. im more concerned with valve float.

im not sure the exhaust bypass valve is a good idea as it completely shuts out exhaust does it not? a proper exhaust brake i would think would still allow air past it, or would it just not be able to close completely as the air has nowhere else to go? i could run onboard air and have a pressure valve so i could set it for any pressure i want, that would be cool.

jake brakes are cool
an "exhaust throttle" doesnt seem nearly as cool..
why dont we use our VNTs as exhaust brakes like Banks Power does on the 2006 and newer chevy pickups?
my dads truck uses the transmission and turbo as the exhaust brakes..
if you set the brake on HIGH and let off the throttle, it will skid the back tires (all 4) without actually touching the brake pedal. but thats with the brake on high and no load in the bed.
