ok many of you know my turbo setup and what ive got done. well the car is only making 248whp at full boost which is 14.5 lbs. the fuel maps are perfect and the a/f ratio is perfect. the turbo for some reason is running out of breath. paul jump in, someone whos been turbo for awhile please help me.

just incase you guys dont know.

t3/t04e 57 trim .63 a/r(real garrett no ebay ****)
zzp manifold
tial 38mm wastegate(14.5 psi spring)
tial 50mm bov
2.5 inch intercooler piping
atp sc delete kit
60lbs
3" dp

bump anyone.

come on i know someone can help. im so freaking crushed i almost cried and i havent cried in over 7 years even in iraq or after iraq. i spent so much time putting this damn thing together and now this **** happens. over a year of research for nothing.

 

wow that does not sound right........ Did you tune it yourself??

 

What do you mean running out of breathe? Not holding boost till red line?

 

Whoa Man! That sucks.. you'll get it figured out though.. don't worry..

Until then.. wanna race!?

 

yeah man im really depressed but searching like crazy to fix this ****. honestly it pulls way freakin harder than it did with the stg2, 2.85, and exhaust, intake. i feel like it used to be a joke lol. and no i didnt tune it myself. were thinking something is wrong with the turbo but i dont have the time to pull it off right now to check everything. yeah it holds boost perfectly fine and pulls hard as hell but dyno only saying 248whp. but i pulled an rsx with a 50 trim on 18pds like it was nothing. so i think the dyno might just read low. who knows, but i got an awesome tuner.

 

who cares about a dyno... it means NOTHING. get some track times.

 

What intercooler? How much timing? Exhaust system?

 

possibly a really bad dyno reading?

 

Bad dyno settings?

 

Email me a dyno graph and I'll offer input.

When you find it, you will sh...
I mean, it will almost assuredly be a forehead-slap 'doh' moment

 

ok. ill try to get you a dyno graph and whatever else i can today mr hahn. really appreciate your help and its nice to see you help a product thats not yours and makes me glad ill soon be ordering your intake manifold. thank you.

 

Bill's good peoples man.
But few things:
FMIC piping, is it 3" on the cold side for the maf?
You still have a cat?
What type of dyno?
also check and make sure there are no leaks on the adapter plate where it bolts to the intake mani.
And one more, where are you getting your boost reading for the waste gate from.

 

I can think of a really good way to test it!

BTW - I straightened, filed the rough edges off of and polished the pulley I got from you. It almost looks good as new!

 

i gave it to you for free right? i dont think id sell something that needed work. just making sure.

 

It was a "thanks for buying my downpipe, here's a pulley for free" deal

 

hope u get it fixed.....those numbers are way low

 

yeah when we figure it out it should be around 320-350whp depending on a few things. i have am awesome tuner but were just overlooking something small i can bet on it.

ok just making sure i didnt sell you something defective.

 

I told you what the problem is already

 

You referred to your turbo as a 57 trim, but what size is it? What compressor wheel? Exhaust wheel and housing AR ratio?

 

t3/t04e 57 trim .63 a/r

 

Ok, how about the exhaust wheel and compressor wheel size?

 

just look it up on the garrett site. T04E housing .57 trim, pretty sure there aren't too many variations on those. beside exhaust wheel trim. but either way, really can't do much til we see a data log and or the dyno graph.
One major thing is he needs to change over to 3" cold side pipoing for the maf since that's probably putting out of range and dumping fuel (that I had experience with lol)

 

Garrett's turbos are listed by GTXXXX. This turbo sounds like a Turbonetics. Maybe something like this.

What makes you think it's a Garrett? Does it say Garrett on the housings?

 

garrett does make non gt series turbo's you know.

 

on garretts site you cant find the t series turbos, they only have the gt's on there,i tried looking for it too, as its the same turbo im going to be using in my build, and to the OP, check for leaks, im sure you can find a boost leak tester, like those used in the DSM wolrd, check more leaks anywhere, and like stated above your MAF is made for a 3' pipe, which is why on my set up im running 2.5 hot pipes, and 3" cold, also you said 15psi, where is your wastegate getting its reading from? the charge piping directly after the turbo? the compressor housing? or the intake manifold(i hope not this one as it will cause boost spikes)?
