DSM 16G Open Dump

[1bapsd]

88?

[TriggaC74]

i need to know about that soung. Did you weld your flapper shut and install a external, or do you use the internal with a seperate pipe on the flange?

[ArktisFuchs]

Which 16G? Seems like it should be a small 16 instead of a big or EIII.

[MachineSwede]

My Volvo can pull harder than that, are you kidding me?

[jonteesdale18]

To all you ignorant to the reasoning of running an open dump it's to flow better. If you recirculate it it doesn't flow as well and there's a chance you'll still get boost creep so throw the exhaust gasses out into the air and it has a 99% better chance of eliminating boost creep!

[love8328]

Supra from hell is an old newb video checkout the dsms on STMtunned where they take stock block evos and talons and run tens lets see ur shit supra do tht oh and this talon is nice i like the no lift to shift he did right there..

[ajra94]

What year and what model ?

[jerryhowell9]

nice piece of shit

[balmilli81]

supra what a fag. It is for boost creep

[dirtydirty505]

WHAT FUCKIN SUPRA

[92eclipsegsx]

Do I hear a little no lift goin on? Nice 2g :)

[xcworrior]

r those e36 M3 rims??

[95GST16g]

Nice Talon.

[kushiikiidlx]

i love supras too.. dsm's are nice too cheap to mod... but supras are way sexier all i gotta say is "supra from hell" check it out

[joe645733]

so slow.

[4BangerNA10Sec]

sounds like air and hallow

[AFinRoo]

alcoholic theres a supra here in FL making somewhere in the 900whp range that runs high 8's on the stock 6 speed with slicks...

[mobsterbillyjoe]

i know bout that supra. not too sure bout the times though. the guys name is Steve Sawicki.

[dsmrider]

this is why you hear the SHHHHHHH people assume its the compressed air rushing into the intake of a vehicle.. which does make a sound for sure.. but the SHHHHHH you hear is the exhaust exiting into the air without being muffled or cleaned by the catalytic converter..

[milkandmeat]

wastegate

[joeybognar]

sounded like he was getting fuel cut as well

[drzflyest4]

thats no lift to shift

[Change08ROFL]

im thinking about the same set up ...would you recommend it ? And is this auto?..if not that was a smooth shift nice

[ColleenzKids]

whats open dump???

[fostytou]

RTFC!

[athletefeet66]

hes pooping while hes driving.

[Master7770]

Does that mean you fart when you vent to atmosphere? I dont even want to know about recirculation.

[AdvanEvolution]

In that case, recirculation means farting in your own mouth. So I guess all humans have to vent to the atmosphere since weère incapable of the other system.

[Master7770]

venting to atmosphere sounds better anyway lol...

[gingerbredman00]

yes but it will cause issues..

crappy idle, running rich, missfires..

sounds cool but it's a bad idea unless you have a maft

[2ndgen4life]

how in thee does venting exhaust gase to atmosphere effect idle one .... running rich is what you want and misfires wtf are you smoking

[gingerbredman00]

join a forum and do some searching, and proper grammar will help people understand what your talking about.

[95GST16g]

An external wastegate will not affect Air Fuel Ratio (AFR). With that said, you don't want to run "rich" but instead at "stoich" which is neither rich or lean, either term is used to describe an undesirable AFR either way. External wastegates are better but more expensive.

[cmspaz]

You tell people to join a forum and learn shit, but you yourself have no idea what you're talking about... You're neither right for an open dump or for a vented BOV, but some mixed up combination of the two.

Open dump'll cause rich condition at full boost, but that can be tuned out. It'll only cause misfires if it goes really rich, and it won't even be open at idle, so it can't even affect that.

A vented BOV will cause a lean idle and stalling during shifts, but it won't cause misfires.

[DSMDriver69]

@gingerbredman00 not really

[95GST16g]

@gingerbredman00 No you're thinking of venting the Bypass valve, turning it into a blowoff valve. You will need to switch to an after compressor MAF to do that. An external wastegate is better in a few ways than internal, but way more costly and more fabrication is necessary.

[dsmrider]

the boost a turbo charger can produce is based on its wastegate.. if the waste gate is closed all the time full boost potential will be created by that turbo.. but we dont do this because of various reasons.. so we let the wastegate open at a certain point, thus releasing exhaust from going to the turbo.. the exhaust is either sent through the exhaust like the rest of the exhaust going throught the turbo.. or its just " DUMPED" into the atmosphere where it doesnt go through the rest of the exh

[98snakeeater]

@ColleenzKids

The place they were heading to drop off the car

[RidinOnRails]

@ColleenzKids an open dump is when some1 runs their wastegate through a tube to nothing or rather into the atmospehere, rather than recirculating it back to the exhaust..hence why u get that "hissing" noise when some1 stomps on the pedal.... the more boost u run with an open dump, the louder it is when u are WOT..

[rotarypsi]

@ColleenzKids waste gate.

[dsmempyre]

@ColleenzKids

the internal wast gate is vented to atmosphere instead of returning to the exhaust system makes it loud under full boost and helps prevent boost creep

[carfreak]

@ColleenzKids

when you take a dump out in the open

[4g63tballs]

@ColleenzKids

When you shit in the woods.

[1995singlesupra]

what a waste of money

[fostytou]

DIAF

[Morpherex]

Says the dumb ass supra driver.

Lets race from a ROOOLLLLLLLLLL

[tpumpiscmibicv]

Haaahahahaha so true :)

[alcoholic420zhotmail]

Supra: where 1000hp will only get you into the 11's.

[Fender927]

What an overexhaggerated claim. Supra TT's STOCK run 13.1 and they 320hp at the crank. Another moron.

[alcoholic420zhotmail]

hey cock smoker why dont you take a step back and fuck your own face? its called a fucking joke you silly bitch. tricks are for kids

[numba1netsfan]

more horsepower doesnt mean shit if u cant put the power to the ground

[Fender927]

Why bring shit up from a month ago?

[MnTC08]

um no 1000hp supra run 9's and lower a 400hp supra will get you into the 11's

[98DSModded]

A right at 400whp supra in the 11's? I hope you're at a track around sea level with some slicks

[JRYANG9000]

@1995singlesupra

I6 your supra is a waste of money.

[TheDSMsucka]

@1995singlesupra indeed, i really dont see the point in this. it doesn't make your car any faster, seems kinda ricey to me but a lot of guys like it so whatever i guess. you wont see me buying one though

[GigaDonk]

Nasty

[fostytou]

I accidentally removed instead of replying to to the last guy's post, but yes, I believe this was an internally gated turbo.

[dsmempyre]

@fostytou yeah 16 g = internal waste gate

[92eclipsegsx]

Mmmmmmmm no lift to shift :) :)

[chicanoDUB]

love the sound

[1slomr2]

I love the sound of the o2 dumps.. I ran one on my 91 but with running an almost open 3 1/2 inch dump pipe it was a bit harder to hear.

[4g63gen1]

AWD is the shit in the snow weeeeee. Also vettes and other high pwr rear drive cars have no chance after a rain shower. I dont even need to try. Quiafe and Kaaz diffs are worth every penny.

[turbodsm7]

Correction Quiafe is worth the money. Kaaz isn't worth its weight in scrape.

[85305]

who the fuck races after it has rained??

[gusu666]

Happens a lot around here.... you see people here know how to drive.

[85305]

wtf?? racing after it rains?? thats some retarded Tokyo Drift bullshit bro..

[OfdeepGreen]

gotta love NLTS

[joosdawg]

ah im riding in an evo

[Attz0r]

altanta ftw

[fostytou]

wtf? This is in the Chicago suburbs.

[idleprechaun]

@fostytou I-88 on the way to the aurora outlet mall?

[fostytou]

@idleprechaun Private closed course... or something like that.

[franciskith0o]

im about to do that to my dsm along with an fp big28 turbo and supporting mods.... cant wait :)

[92eclipsegsx]

Sounds great :)

[jwuonog]

sounds good. just wondering, was this on the way back from a meet?

[evogst4g63]

what bov is that? HKS?

[df4iguy]

correct!

[turbodsm7]

I don't understand how people can be so stupid.

Its a o2 dump. All that means its that the air coming from the wastegate is not routed back into the exhaust. Internal or External. Doesn't matter.

[fostytou]

Cha Ching!

[Hefty1468]

2g eclipses have a factory external wastegate. 1g eclipses are internal as are evos. check out dsmtunersDOTcom.

[fostytou]

You couldn't be more wrong. All DSM and evos are internal wastegate stock.

[92eclipsegsx]

roflcopter

[shadowdreamzk20]

is that fwd? pulls pretty hard. i had 2g fwd with big 16g at 20psi. that thing was a blast to drive.

[johnm11690]

fwds can keep up with awds on the highway... but the awd will rape the fwd at any standing start... or turns for that matter... but they are all fun to drive none the less

[turbodsm7]

Its all about the driver. My FWD with Quiafe LSD gets out of the whole faster than most AWD's because I can drive my car. And FWD is faster in the long run anyway. Less moving drive train parts and a lot less shit to break.

[johnm11690]

This is somewhat true, as the fwds are considerably lighter, but using your logic, I know how to launch my awd pretty damn well, so I am just as quick out of the hole... with much more power to the ground on turn exits... but then the guy that dummied his front halfshafts will pass us both with rwd efficiency haha... comparing driving skill is highly irrelevant anyway, as i'm sure none of us will ever meet to prove it

[turbodsm7]

Yeah true. Ive owned AWD and FWD both are fun for their own reasons.

[df4iguy]

its AWD

[jyturbox]

do u have an internal or external wastegate? ur car looks like it pulls pretty hard! Do u get any side effects from an open dump? I own a 99 gst spyder w/MHI EvoIII 16g.. just doing some research trying get more power out of the 16g without messing w/the internals or cams...

[fostytou]

You don't really need to mess with internals for a 16G, thats a waste of cash. I have an external on my 35R powered 2g, but I believe this car is internal wastegate. My evo is internal. Internal is fine unless you are spiking or creeping, but that could indicate a different problem. Only side effects from open dump are ridiculous amounts of noise when your wastegate cracks and the smell of spent gasses in the cabin at full boost.... personally I love it!

[jyturbox]

Thanks for the advice. ONe more ?, with a turbular exhuast manifold, SS tubular O2 housing and 3" turbo catback exhuast no/catalic, I get this gassy smell coming out of the exhuast. Is this Normal?

[iammalloy]

Usually any car without cats has a bad gas smell, but a good tune helps.

[df4iguy]

its and external wastegate (tial 38mm) off of the exhaust manifold.

[turbodsm7]

No its not.

[jyturbox]

that an open dump refering to O2 housing right?

[fostytou]

Yes, the port from the wastegate is a tube that just goes to the bottom of the engine bay and vents to atmosphere.
