Well since we made 850WHP on the GC with the smaller turbine housings, and the same compressor housings 3 years ago, and broke all the records at the time, all while having no issues, things were running very efficiently for max effort testing. Here we have another person that is putting compressor housing size at the top of the list of variables to turbo efficiency when in reality it's at the very bottom. As Garrett says a turbo is relatively insensitive to Compressor housing AR changes. The biggest factor for turbocharger efficiency is turbine wheel flow and turbine housing flow/AR size. If you want to go back and find the logs they were posted back then, as we always posted logs.I'd love to see how efficient 850hp is on TD03 compressor housing, have you guys got some logs ?
As for the people saying are these tested, yes of course. It's a GC with a better flowing turbine housing and better flowing compressor wheels. It's not a new product it's a redesign of an already well-proven product that has been tested for years. With that said, we have a flex-fuel stock motor car in for F-RB install now, we will be doing that on 91, and E85 shortly. Then of course we will test them on the shop car at max effort, which means removing the stage 3 kit to do so. We are just waiting on a motor to arrive to begin that process.
They won't.In for results, if these can spool faster then my single and make the same power up top. I might be interested in switching.
You never know, also would love to see a 60-130 with them given nico did a high 4’s with laggy singleThey won't.
Any reasons for GC lites 2.0 owners to swap to the new lites CRHAs?
Well... That bickering that you experience is just the inability of people able to have a proper conversation and the inability to take criticism. We all experience these issues nowadays in every level. Not saying i'm a star in this myself but the new standard seems to be calling insulting people or release bogus products when they don't agree with what someone thinks Very sad.
Everyone takes thier own stance, or method of dealing with this. VTT decided to put thier effort in releasing the same TD03 limited turbo's what seems to be just a reason to bash a competitor. As hilarious as this is for us, from the business side of things it's not very professional.
Slapping together a turbo with a mix of fancy colored parts and write some great promises on paper is something I could do too to be honest. What would have been professional is delivering better turbo's with the actual improvements, (flow)data, long term testing and dyno results. That is something no vendor has done before so doing that would actually be "next-level"
But ofcourse another way of dealing with it is waving away all critisisms and tell yourself that cramming a 17T/19T wheel in a TD03 compressorhousing with a 2" intake and 1" outlet is a good idea for long term reliability. So many times untill you actually start believing it
Spool faster -not a problem. Making the same power up top really depends on config and how much power you're making. Vague answer, I know, I just have no idea what you're running and want to be fair. The spool usually goes to twins with the short manifolds. Ziiing! Gone.In for results, if these can spool faster then my single and make the same power up top. I might be interested in switching.

Looks good and I would like to give these a try. I've been looking at Vargas turbos for almost two years now.
I like that they develop their own products. They have a long reliable track record. They also have good involvement and support for the customer. Most of all they have credibility. I see it on the dozen or so forums I've been on regarding the N54 platform. They do have some complaints, but it's marginal. I can't say the same for some other names I've looked at.
So, once the stock turbos on my e60 535i bite the dust I'll be trying one of their turbo solutions.
All turbos fail if you run them out of their efficiency range and that's what most on this platform are doing.
I'm getting a set of gc+ soon and we will be running it in the race/street car we are starting in the new year.
Can't wait as I'll finally be able to run the RHD v-band outlet pipe on these and ditch the silly silicone outlets which can be a bitch.
Some exciting times coming for the n54, we aren't done with you yet.
To be fair, I made 700whp on dyno with stock engine, not includeing the nitrous on top. But ran into fueling issues.Spool faster -not a problem.
