Important PSA regarding improperly built TPC20 Turbos

[El_bigote_AJ]

People trying to defend a company when proof is provided, when you can get a Mamba for half the price which will just work.

Before someone decides to make chinese turbo comment, just save yourself the embarrassment and step away from the keyboard.

Was anyone other than someone that’s happy with thier tpc defending the company though? Sure I could have missed a post or 2 but what I’m picking up is less if people defending tpc and more of questioning your extrapolations of “data” I surely didn’t, and the artists formerly known as badhombre760 was more focused on the logic of how a company would stay around with such bad percents…

Not even sure there was anyone defending TPC actually. One guy came forward and flaked when I asked for logs. For all we know, his turbo could be bad and he just don't know it. It sucks that this thread got moved and now someone could get scammed. It's not okay if even one more person gets scammed.

My TPC25 works well. All my logs are public. Will be grabbing some new logs soon but I have no complaints.

Self tuned on OS. Was pushing 34psi with 60% wgdc @7k rpm in third. Switched to a rs3 pump late last year and am getting back to tuning it.

Prior to that, Gary tuned me when I was on Eurodyne at 35 psi before my clutch left the chat.

This one looks good. TPC25 is no longer made though? People probably shouldn't buy a new TPC turbo because of a log from a model that isn't made anymore.

But people should definitely Not buy ANY tpc turbo because of some bad logs?. All companies have had failure. Dbv2 eqt mabo. Even the oem is38s had failure.

Are you beating down the castle gates of all turbo manufacturers that have had failures?

Bunch of TPC38’s with performance covers making good power. One tuned by @railroader ran sub 7 60-130’s stock block. @arob157 running strong numbers as well.

Those don't count.. doesn't fit the narrative

I just have an important question for the group.

I had 4 ampliforms and I hit a pothole pretty hard, enough to crack one of my wheels. I got it repaired but decided to buy a 5th wheel as a replacement while I was waiting for the crack to be fixed.

Does this mean that all ampliforms have a 25% failure rate, or a 20% failure rate becaue I did buy a 5th?

25% failure rate, since at the time of failure, there was only 4. But since the failed one was removed, it changes now to 4/4 success rate, so a 0% failure rate. But in total, you had 1 out of 4 fail initially, now you have 0 out of 4 fail, so really you had 1 out of 8 fail, so it would be a 12% failure rate. But since you have that spare wheel, it would be a 1 out of 9 failure rate, dropping the final failure rate of Konig Ampliforms down to 11.11%.

So we can deduce the failure rate Ampliforms is not as bad as my failure rate of a statistics class.

You have a 770 right? It's supposed to make 40 psi according to TPC, will your turbo make 40 psi on your setup? Ask Gary if his will reliably. i don't think Gary wants to get involved in this. I think you should leave him out of this for his sake. Narrative. You're barking up the wrong tree without the right info.

Show me a 40 psi log from your car, and then you can talk.

Define bunch? Because if we extend it to "people we know", my number goes up to at least 10 for bad. So even if there are 20 good ones we can say "we know of" that are good, there are 10 which I can say I know of as being bad. 50% is not good. You don't see these numbers today with the Vortex turbos. I just do see why anyone would take the gamble. Nobody is denying some work, I'm just saying he failure rate is higher than the competitors.

Look at you.. Pointing at a turbo maker that no longer makes hybrids, Mabo, and IS38s which are probably spun way out of their spec'd operating range. Why don't you just pick on EQT TODAY? Tell me about all the people coming forward about failed vortex turbos today. Defective TPC turbos are still happening today. Talk about today. The danger is someone spending their money on a TPC, Today.

i had 2 defective vortex xl units, one ordered late 2021 had a crack on the hot-side near the waste-gate, was warrantied as new as it was a 0 mile unit. jan 2023 and its replacement blew up at 25psi with (1200 break in miles on it) on the dyno in march, with its new owner.

i was never asked to keep quiet or not post about it. i didn't feel the need to sound the alarms and make big ol' shit posts and witch hunt EQT
they did what they should have, and fixed the issue. now the new owner was also taken care of, and they are going to warranty that one as well.

eqt took care of me, and i thank them for that. i didn't run to the forum to tell people not to buy them. nor did i ever dissuade anyone from spending their money how they thought appropriate. why... because i understand that things happen. and i knew that eqt would take care of the issue, and also any potential issue they encounter. *as they or any stand up business should*. so it was a non issue.

im not here to pretend the sky is falling because turbos do fail. everything has a margin of error.

I am also not pointing at anyone, i was simply stating companies names to explain that all companies at some point have had either quality control issues or bad designs. it happens. this is nothing new


this is today. this happened . and it is just like your stories about friends, and turbos you know of that failed. so if you do not find value in my experience and in my stories. do not expect any of us to find credibility in yours.

You're highlighting the problem. TPC hides the failures, doesn't help people with turbos that don't perform. EQT stands behind their products. Again, why take the risk with TPC.

Also, do you have that 40 psi log? If you have a TPC770, you deserve a 40 psi capable turbo. Unless TPC is advertising a "hero pull" on their site.
