Re: T-25 turbo project fail
 

I had a revelation today. Went tuning, and for some reason there my car would misfire at about 4300 rpm, eventually i realized that it was a ripped diaphragm on the wg that VadimkaG sold me (which was also a cause of many headaches with the T-25 build) My boost gauge only reads to 10 psi which is why it took so long to figure out.

A pox on your house Vadim if you sold me this pos knowing it was trash.

So i threw on another wastegate and got it tuned a little bit. Running 13psi right now (had to play with the boost cut feature to figure this out) and the 450's are almost maxed.

Vid will have to wait, blame Vadim for causing me an necessary headache.

Did it the other way since i was originally planning to have an e cutout running through the bumper. Pain in the huevos to reach oil line and bottom manifold bolts with the hot side on the left.

everything is looking good and glad you got it figured out. vadim sucks i wanted some vid :7

The wastegate worked fine, but if you want too send it back, I'll give you money back and shipping. :3

Re: T-25 turbo project fail
 

Was that a spring holding the flapper shut on the t-25 setup? If so that was probably your problem.

The spring was allowing the flapper to open up while the wastegate was dumping. That would explain why it felt like it was dying on the top end/

Re: T-25 turbo project fail
 

No, it was baling wire. When i first put the t-25 in and started tuning, i would get crazy misfires when i hit high boost. (because i have a crappy boost guage all i knew is that the boost was above 10 psi) i cut the spring down several times until the misfires stopped (i cut it down enough so that apparently the exhaust pressure would open the wastegate). And just yesterday i figured out that it was a ripped diaphragm on the wastegate that was pretty much letting the turbo boost as much as it wanted.

But that still leaves me questioning why it would misfire at high boost? AFR's were fine, plugs were gaped fine.

I would like to send it back

Did you say you cut the spring in it, it had a Tile spring in it? :3

Re: T-25 turbo project fail
 

I cut a different spring. your tial spring is intact

Re: T-25 turbo project fail
 

$50 is fine?

Re: T-25 turbo project fail
 

That will work
