LETS TRY THIS AGAIN

[94'BooSTED-GTtoo]

i noticed there was a lot of oil spitting out right there, so i took that clamp apart, and thats what i came up with.......idk if its still spitting oil like it was because the first oil is still burning off, wasn't doing this before,wg too firm? turbo shot? now, the turbo is waaaaaaaay louder, and i did a couple little hole shots in my driveway about 20ft 1st gear, seems to have alot more ba!!s than it did, still have to take it down the street, seem to be making a little progress i guess.......

I'd be careful with the hole shots and ripping on it. You have issues which would make me very weary of the tune as well, last thing you want to do if figure out whats causing the massive boost leak, fix that then boom blow the motor because you didn't take it slow. Do you have a wideband, fuel pressure gauge, boost gauge? Did you unhook the exhaust in the picture or was it like that?

 

[94'BooSTED-GTtoo]

hey wouldnt ya know.... could it maybe be the 18 chamber mufflers on this thing.... lmfao, not flowing through them now, and this thing is pulling hard, not getting crazy on it or anything but, it's 360 difference, thinking about cutting the pipe back where it splits and dumping it there, would that be ok to do?no mufflers... im sure it wouldnt hurt

 

[94'BooSTED-GTtoo]

i do have a wideband, and also a guage, but its after the split now, but will be hooked back up once i delete the restrictive mufflers, i do also have a boost gauge, the exhaust was clamped together there, and split apart, assuming from the back pressure from these 52 chamber mufflers, now the blow through seems to be less but its still happening

I've had the boost brothers kit on my old 95gt. As others stated check for any possibilities of vacuum leaks. I had to ditch the BOV the kit came with as it leaked badly. I think the wg spring that the boost brothers kit comes with allows for around 6-7psi. With any forced induction car be sure to get a tune.

Also how is this car being tuned? Factory ecu with a chip? Standalone? do you still have a mass air meter?

 

[94'BooSTED-GTtoo]

there is no maf meter im pretty sure, idk really how to get it tuned.... whats best?i would probably look for a chip on the stock ecu i guess, easiest, idk if there's anywhere near me (flint,mi) that tunes, im sure theres something down by Detroit but thats a haul with no access to a car hauler

 

[94'BooSTED-GTtoo]

as for now, the wideband is unhooked due to it being on the split side of the exhaust thats hooked to the mufflers, im going to get under there and disconnect it from the collector and reattach the pipe with the wideband in it and run open exhaust for now, its a whole different running car now since i unhooked it from going through the mufflers, the manifold leak went away, heat under the hood went away, idling way better, the hot air blowing through the cold side input stopped, because it can flow freely now..... so i guess once i get the wideband back in place i'll see what it does, because the numbers i was seeing before was with hella back pressure from the exhaust not flowing

Turbo cars hate chambered mufflers for sure. I'm running a set of slp loudmouth 2s which are a complete straight through muffler. The turbo will muffle sound a ton so no mufflers are fine.

Whats best for tuning? I would recommend a standalone ecu. I ran a plug and play megasquirt on mine and loved it. It gets rid of your maf meter and O2 sensors. You just need to have a wideband and IAT sensor. The map sensor is built into the actual ecu box. In fact I have a walk around video of my entire old car I'll post below. Show where I mounted the ecu in the glove box.

i would have no idea where to even start to tune it myself.....is there guides out there to help me get started and learn? or would that be a total disaster? so you say they are plug in and play? i also got the lighter spring back in the wg, but still only building 1-2psi, thinking its the bov, that's the only thing that hasn't been swapped or messed with, besides the turbo, but the car deff loves not flowing though the 55 gal drum mufflers :thumbsup::headbang: and to everyone that has been giving a helpful hand..... :notworthy:

look into local dyno tuners. You will be looking at a couple grand for a stand alone system and I am not trying to be rude to say that your not ready to tune yourself. I am hoping I am and pretty sure I am not...

Not a turbo guy but I thought you either ran a BOV or a wastegate, but not both at the same time?

Wastegate is there to control the boost the turbo makes where the BOV is there to relieve that boost pressure when you slam the throttle shut, you really should have both on any turbo setup.

 

[98snakehorse]

I would definitely recommend going to an experienced tuner. It takes quite a bit of tuning experience to get it right and is the most important part in having a good reliable running car. The lighter the spring you put in the wastegate the less boost you will make. I would start trying to do a boost leak test to find out where you are loosing pressure.

Here's a good how-to video from mighty car mods to help diagnose possible boost leaks you may have.

Also - I can guarantee if you run around without a tune designed to support boost for your engine/boost setup you are going to have issues down the road.

i have botha wg and bov, wg doesnt seem to be opening up, but while when i change the vac line to the other fitting, bov seems to be working as it should though...? is it because i have the exhaust piping off?

thats pretty much how my setup is, i think the location of the wg is the problem...?

Shouldnt be thats where my wastegate was. If your only running 1-2psi are you sure the wastegate isnt opening up? Did you make sure to install the fire ring in the wastegate?

 

[Lanter]

Wastegate won't be opening unless you have an under 2 psi spring in it. The wastegate should get a boost reference from the turbo compressor outlet cover or close to it. If you have a 5 psi spring in it the wastegate will stay closed under 5psi and begin to open once boost pressure overcomes the spring pressure that holds the gate closed in this case close to 5psi.

Checking for a fire ring is good advice, that would explain alot

Pictures would answer sooooooooooooooooooo many questions.

You do realize circumventing a ban is grounds for overban?

I think the reason we are letting it slide is the complete attitude adjustment. Seems like lesson learned.

You say you plan to stay around 6 pounds. Boost guys help me, isn't that barely more than atmospheric pressure and would make little to no difference? Or is that old school thinking?
