alrite, so today was retune day....

went pretty well. it was only 50° out, so i had all kinds of traction problems. 50° and falken 512s are a bad combination. so after him bolting down the front end with what he calls his drag bar, we got most of the traction loss settle. the dip higher up was from slightly spinning

all in all, good day. heres a breakdown:
57trim / oem b16a cams/ oem throttle body

tga 6157 turbo / gsc n1 cams/ s2 alpha 70mm throttle body

tga 5857 turbo / catch can setup / act streetlite flywheel.

changes are a progression from tune to tune.

todays results

comparison from last three setups

 

so after about a month of having the catch can setup i decided to empty it.

 

Am I reading the graph correctly for the torque? Under 250 ft lbs @20 psi?

 

yep 246 wtq.mustang dyno at 416 elevation i believe. my torque barely ever went up. i do think it would have been higher if the tires werent spinning so much

 

decided to take a shot early this morning.still needing a go pro, and tires. my crv will be paid off in a month. so thall help expedite the tires fund. but, having a newborn kinda dampers everything.

 

Car looks good man. What tires and size are you going with?

Congrats on the new born. I have a 5 week old little girl myself.

 

haha i have the worst possibly size ever. i have 195/50/15s falken ziex 512s. when i ordered wheels and tires years ago, i didnt think i would be boosted. im planning on 225/50/15s this go around.

my youngest.

 

Good call on the 225/50/15 tires size.

Happy healthy looking kido too, they are a blessing.

 

thanks

 

just now gettin around to installing some braided steel brakes lines. and the rbf 600 fluid. any hints for gettin the out of the bracket on the fender well before i go out there.

also gsc released their billet t1's couple months ago. thinkin bout pickin a pair up for next time i decide to change setups

 

brake job went smooth, then the last of the lines snapped above the nut. buddy brought his kit over then re flared a new fitting for me. man these lines and rbf600 fluid works really well. definitely need tires even more now.

after talkin to a few other members. i decided to make a little turbo inlet intake. i had some spare parts in the garage. with straight coupler, and a 3" 45° elbow, i came up with this.


not really worried bout sucking water up as the filter wont be submerged. it sits higher than the oilpan. so ive noticed a reduction by 13-15° from previously. IATs were 117° after a few heat cycles. havent tested anything else. waiting for a warmer day

 

I like the intake idea. I'm gonna do the same. Simple and effective.

 

thanks. still not quite sure how i feel bout it. some reason i feel like it should be longer than just an elbow. but, if it works it works. ill take a shot tomorrow near the fender well

 

so for the last month or so ive been chasing down boost leaks and lookin for a exhaust leak. after doing all new vibrant gasket all around, the car remained the same. so this morning i snapped the head off a bolt on the manifold/ turbo flange. in process of takin everything off, when i get to the wastegate, i realized the valve wasnt closed. any reason why its open. it has bout quarter inch gap.

havent search still in the garage wrenching, and drilling this snapped bolt out. pics up alittle later

 

Hello boost leak!!! Yeah it should be closed and be pretty damn hard to push open.

 

yeah tell me bout. for whatever reason, i get this gap if the set screws are assembled on the valve shaft lip how (assuming) it should be. if the sets screws are on top of the lip, or on top of the shaft, the gap closes.

prolly gona be ordering a new wastegate come monday.

 

the fire ring is still there right?

 

dude I've seen so many tial wastegates fail. My tial did the same thing and is stuck open. My knockoff is more reliable

 

Don't be so obtuse, by giving credit to knock-offs. If you don't like the Tial, get a Turbosmart instead

 

yep, the fire ring is still in. the gate went from stuck open with a gap. to unstuck still with a gap. honestly, i cant really argue with its service. its been in use since 09/ 2010. all my other parts on my car since then has been dwindling down aswell.

i think my aem fpr is shot aswell. after driving for a bit, the afr bounce around 15 or 16 no matter how much fuel gets added. but it fine when not so hot. **** that parts been on my car since early 2009. thought i read another member having this issue aswell

 

believe ive found my issue. one of the big set screws underneath the diapharm. enabling it from lowering completely. havent taking it apart just yet though

 

 

i love boost lol. problem resolved.

 

So in conclusion when was positive pressure and full boost reached on each turbonetics turbo?

I'm looking at the tga 6157 as well but looks like the tga 5857 produces the same numbers just with more torque and a better powerband. Motor its going onto is a stock k20.

 

makes sense. the smaller compressor wheel with the same exhaust wheel as the 6157, stays within the 30% diameter differential. (meaning the compressor wheel and turbine wheel sizes are a better match to one another). Plus the compressor housing for the TGA5857 was smaller (IIRC) so, yeah.. that would work.
