Not sure what the bad rep is about VTT GC's. There are definite reported failures of these but Pure Turbos also have reported failures with high psi use and track abuse. But everyone talks up about how Pure Turbos are infinitely reliable when in reality they are definitely not. Every company has its strengths and weaknesses. Each to their own I guess

Very interested in hearing more long term feedback on the Vargas GC reliability. Some info that would help too would be how much boost they're running and how the car is used.
Looking forward to hearing more feedback on the intakes paired with any upgraded turbo. In theory, it no doubt makes sense. We have some high horsepower local cars all running stock intakes, so would be interesting to see more empirical data. Quote:

I have the GC. I drive my car everyday. Just passed 4K miles. Tuned by F80paul and currently running 30psi. And making 620/640.
I wonder what is considered pushing the turbo to hard. Is 30psi to on the edge. Or is it like 35+. |

Could Vargas have been more eloquent in some of their responses?? Sure !!! Is the fit and finish 100% ? No but it's within reason and usability. We seem to be expecting perfection at a fraction of the competition $$. My turbos are outperforming most pure's on pump . I'm happy! My install wasn't seamless , we had hiccups, there were times I was frustrated and pissed off . Yes Tony can be short with people and probably better at building turbos then relationships , but Chris was there on the phone working through it. Tony is responsibly for making turbos for less money which made my car fast AF . End of story !! The final result was excellent. Spool is phenomenal. My overall build saved me thousand. It's a freaking joke , we are spending less then 10k to build a 10's car . Wtf ? Even less if you resource used parts. I had play in one of my stock turbo when I removed it!! So Little mileage too . I guess bmw turbos are like eBay !! Lol We've become a society condemning expecting perfections with little to no grace . My advice to the Op buy within your budget , expect failure and success it's a part of process . Enjoy the process . Budget a % for unforeseen items , plugs , engine mounts etc . And go in knowing you can BLOW your engine, or a turbo , and if that happens it's the price to play at these numbers . Also kindness understanding and patience goes a long way .

Tf... 30psi and only 620whp..? That seems really low. What mods exactly

The usual with upgraded turbos. That’s on pump 93. And these are just the GC. Not the GC+. And I asked Paul for a non kill tune. And that’s what they advertise you can make more with meth.

I'm running the gc with stock air boxes and stock exhaust . I'm hoping to squeeze a bit more with intakes , exhaust and meth . I still ran a 5.77 100-200km on just pump 93.

Running them for over 3 months of hard weekend driving. So far so good, or loving them! Currently at 31, but crank it up to 33?? Need just a little more power. Running lpfp along with pi kit.

It's an oversimplification but you can make power with more boost or more timing as allowed by your mods, fueling capability, and octane. It's common on lower octane fuels to run a higher ratio of boost to timing targets, it's a little hotter on everything but still makes some pretty good power. A little meth injection would go a very long way in reducing boost targets for a given horsepower target, or increasing power output. Keep HP the same, add some methanol injection and turbo shaft speed drops (good) timing capability increases (good) and EGT's will drop (good). All a tradeoff. This is why I recommend the pump gas guys who want a touch more and/or are afraid of meth kits on the car... get an aggressive pump gas tune timing wise and use water/meth to make it conservative. 'course then we have the guys running E98 spraying meth and with a 200 shot on top of it all lol.

have to say it has been problem after problem with my GC turbos,
i don't want to start a debate here as i don't really want to make any trouble whatsoever. they failed on me(whining and smoking) (the housing itself broke and rotates like crazy) after 1.5k KM and i sent them back to VTT (keep in mind i live on the other side of the world lol), they came back and after just 500 kms they started whining again. emailed Tony and he said that the whining is caused by other things other than the turbos lol. i asked for a new set to be sent to me instead of this broken set and they declined so i guess you live and learn.

The turbos started whining on the same day i got them back from you, i talked to tony and he said to troubleshoot some more and i did, everything on the car is fine so the whine is coming from the turbos AGAIN and he simply ignored my issue. It doesn't take much to know that the turbos are dead even after paying lots of money to send them back to you for repairs they broke again after 100 kms. I am not looking to start a debate im just stating what happened. I run my own company and when the customer is not satisfied with the product i change it no questions asked, that's where i am disappointed by your method handling the situation and have to send the turbos back for repairs instead of a new set, and even after doing all that they break again 🤦🏻*♂️ I will send you a mail showing you the turbos and how the housing rotates freely causing many problems one of which is the whine

Ok, got the facts.
Nevertheless we offered to take a look at them to diagnose, sent the link for repair/warranty inquiry. Customer declined citing expensive cost of shipping turbos back to us, and stated that what he had wanted was a new set shipped to him. We are unable to do that. It's always unfortunate when these things happen, but generally speaking we need to see the product in hand to address mechanical issues, particularly on something complex like a turbo. They were purchased in 2018, it's now most of the way through 2021 and we're still willing to work with the customer, and can offer a discount on a rebuild should they require it (we cannot tell from a couple of pics... this requires bench top disassembly and diagnosis). That's it in a nutshell. We acknowledge that the customer is frustrated, and that is unfortunate, but the way we would resolve this is to look at the product and diagnose with our specialized equipment. Chris |
