he just traded his 98gti for a 00 1.8t gti. he loves it and it keeps up w/ my turbo. he doesnt know ****, but i let him think he does. he keeps ging on about a diverter valve and how he wants to replace it w/ a bov. i asked him what a diverter valve is and he didnt know. then i asked if he could just put on a bov and he is positive he can. then he said after he chips it, he plans on putting a MBC on it then up the boost from 15 to 20 w/o adding more fuel. is he dumb? i wouldnt think he could even use a MBC control cause the computer would see something is up and reset it or bypass it. also what is a diverter valve? i asked him and he just said it sucks. he also thinks he can just get the bov and put it on, then i said i think he needs a hard pipe, but he he doesnt. oh then he wants a CAI, which in his mind is a p-flow w/ a heat shield. so......... anyone know anything so i can tell him before he thinks he is god w/ his 1.8t

do a search on the diverter valve I asked the same question about a month ago

ATurboCivic2NV

i think that is a valve that prevents over boost

spooled20v

hi, im the "friend" and i didnt have any turbo questions, but since you had a question I will give you the answer
if you have a blow-off valve, this air will be let out to the atmosphere.
If you have a diverter valve, this air will be recirculated back into the intake tract.
second, a p-flo is not a CAI....and i need to do nothing more than put a chip in and be running 195hp, and yes BRAKE horsepower.

EDIT: ps i miss the friend and yes his civic IS faster than my GTI

whats BRAKE horsepower? I always thought flywheel and wheel HP was important, whats brake hp?

falcongsr

thats the maximum amount of horsepower you can make before you brake something.

intekragsr

bhp=fly wheel hp
correct me if im wrong

BlueShadow --> <--falconGSR

DOH!!!

To correct the GTi guy! A BOV is a BOV. Your supposed diverter valve is an OEM closed loop BLOWOFF VALVE so stop confusing yourself!

spooled20v

i hope you arent trying to correct me (being the gti guy) cause I gave the definition for Mr.Beastyfag a bov vents to atmosphere, and a bpv/DV are basically the same thing, the excess is RErouted into the intake track.....Dvs are cheaper and better for the purpose anyways....besides, no one will hear anything as i shift driving by

BlueShadow

yah, but where's the fun in that?

Dee

Yes, I am referring to you and BOV's can be closed(DV as you call it) or open loop! Once again.. it doesn't matter what goofy little name you give it, a BOV is a BOV. Most of the people over here that have cars with MAF sensors run closed loop aftermarket BOV's because open loop BOV's on MAF equipped cars tend to cause erratic idle. The majority of the people who run open BOV's do it just to get attention but a lot of people run an open DIVERTER valve because they do want to waste time running a tube back to the air inlet for the turbo.Running a closed loop BOV will also help decrease turbo lag if it exist. We can only assume that you are referring to an OEM BOV when you say DV. MOST (notice I said MOST) OEM style BOV are tiny and have very weak springs that tend to easily leak if you boost past their pressure rating. Diverter valve = recirculator valve = blow off valve. Saying a DV is not a BOV is like saying a turkey is not a bird!

multi-valve

Brake horsepower refers to the fact that the engine was tested on a brake-type dynamometer.

spooled20v

i dont want people to hear my bov, or bpv or DV or anything, and ur right there is pretty much no lag at all, but with a better dv it will help with spoolage between shifts cause the stock 1.8t DV cant hold much more than 200hp anyways

BlueShadow

I dont think that's 195 HP with 20 PSI

and before that ..

spooled20v

its at 7psi stock and the chip adds approx. 8lbs more giving in a dyno (w KN di.) at 196 whp .... way to go vokswagen is right i would say, I spent 15k on a 00 1.8t gti with 14k miles and i put 500 into the car and im runnin 14s, im happy

Tofurky

thats some piece of machinery you got there. 195whp at 15 psi? come on, admit thats funny.
and if you really wanted, you could've spent 3500 on buying a 5.0 and also seen 14's.

ElectronVTEC

A few things

MBC's don't work on GTi's, boost is electronically controlled via the ECM/ECU. You get a "1.4 BAR chip" and you boost.... 1.4 BAR.

K03 turbo's are tiny. They are like 3 cylinder Metro motors... yea they're internal combustion but damn, they get laughed at a lot. Point is, you may have "turbonium," but a T3/T04E it is NOT.

DV = BOV

My buddy's 1.8t is chipped, new exhaust, P-Flo intake, new "diverter valve" and on the KO3 turbo he managed a 15.9@92 or somethin like that. He can't drive, but he's not smoking much around here. Point: your car has potential, your attitude does not.

I hate sauerkraut. EV.

TurboInteg95

well said Electron. In VW's defense though, there motors are not junk. Yeah, 20 psi, 200 hp, blah, but you have to remember the turbo is the size of our fist. If you took out the computer and the turbo and replaced it with a properly sized turbo and engine management system you would easily be up there in the HP. Also, those 20v heads are simply awesome. I would almost not mind building a VW.

spooled20v

my attitude, dude, dont go talkin about me, you know nothing about me. and you did not make any points period, talking bad about a car company is pointless.

Tofurky

at the moment, my turbo gsr is a three cylinder. well sorta

ElectronVTEC

Where... where did I belittle VW? I did not. If anything I belittled my friend cause he can't drive. VW did nothing wrong, the 1.8T is a GREAT car, but that doesn't mean its the best thing on the streets. Ultimately, its just as much money to build a high-horsepower VW as it is a factory N/A Civic/Teg. As far as the car is concerned, i wouldn't kick one out of bed. My friend's IS quick (he's since gone to the KO4 turbo) but its quiet, almost unsettlingly so. My car's the opposite... its loud, its noisy, you can tell I've worked on it. I'll reiterate... I don't have a thing against VW (the sauerkraut thing was a JOKE), my thing was against the attitude you put forth in your post. EV.

beastyboy81

i told you you couldn't use a mbc. and i also told you the dv and a bpv are the same thing just different names. anyways, about the dude who ran a 15.9 w/ the chip and all the other goodies, what the hell was in his trunk? fukin bricks? even if he was a bad briver he would have had at least 196hp at the wheels w/ just the chip and k&n drop it, its dyno proven. are you sure it wasnt 14.9? that doesnt even sound right. like i said everything in your vw is controled via the ecu, so you cant just put a mbc on, and after you put the chip in and you want still more boost your gonna have to add more fuel somehow as to not run too lean. just spend the $$$ on the chip/k&n/exhaust 3" from turbo back/ nice coilovers(real ones) and yopu should be happy then. so if he puts a new dv on like he was talking about and does the chip, does he somehow have to adjust it for the new boost pressure, so as to not leak or open at the right time? or is that somehow already set for the chips pressure from the company that makes it? or is it adjusted like my bov?

spooled20v

yah i know all that. im lookin at the HKS ams ssbov anyways, its 300 but it slaps on, and its better thana dv and sounds cooler besides, i know your 18 w. kit is faster than my 1.8 but im havig fun with it im just gonna wait a week n up-grade to k04 ...not much bigger but bigger ;-)

dbman96

K04 is a pretty small upgrade for the money you put in. Why not go to a K16 or 26 or something. I've got one of those sitting on my desk at work right now, it's slated for a future audi project. Even a T3/4 - the turbo is so much cheaper it would more than make up for the little bit of customization you need to do to make it fit. Be creative.
