bro what? no kind of car description, or tune or setup. giving off advertisment vibes.

Im sure they are good turbos but this post is useless without more details

I would agree that it's a plug for PP Turbos - you'd know it definitely is if you are a part of the FB group. Do not agree that this post is useless though... Car description is there... C7 S6, along with supporting mods and what was used to tune it (Sean, using a DS1). What more info do you want? Just ask.

Those numbers are very impressive, especially on stock cooling and a dyno setting

To be fair, all that extra info was added after I commented lol

As impressive as E85 numbers are its not available in all markets, Id love to see where these builds tap out on pump 93/91.

You can just factor in far less numbers - anywhere from 50-120ish HP less on 93, and likely needing meth to get there. 91 octane even more reduction. I believe the idea here in - testing the potential performance of a product and/or the limitation - is to utilize whatever fuel has the most "bang for the buck" and fairly widely used (E85). Would be good to see the performance numbers throughout the octane levels, but you can do some easy assumptions it's just going to be quite a bit less.

his fueling was his own creation LPFP which is an independent Hellcat pump ran via its own line and Y'd into the other fuel line in the engine bay to the stock HPFP's. He is also running upgraded injectors....so not for the common build as its an engine out procedure, and about 1400+ in upgrades as well as the custom mapping/tune

Im not knocking it, but just making sure the full story is there, so the joe schmoe doesnt come back here bitching that they are fuel starved on a stock LPFP, stock HPFP, stock injectors trying to get E85 to work

Haha yeah when I saw the post it just had the thank you message. Glad to see that’s a c7 S6, it’s inspiring
I’ll probably go PP if my rs7 turbos ever go out

[Jong90]

Sorry for the light plug Jon Gronewold (Pinnacle Performance) here I have never really been active on Audizine a lot of you guys know me in the Facebooks groups 🍻

I would truly hope the Joe Schmoe - really the majority of people in this forum - would ask more questions about the set-up before going the same route. Nevertheless it does the point of this post - shows the capabilities of the turbos he sells, when tuned by a knowledgeable/capable person, with a great tuning product.

I would even wager to say the majority of folks know by now, that larger turbos cannot support E85 and high content by itself; without other upgrades.

Part of a plug and teaser is for folks to gaze in amazement, but also be intrigued to ask more questions about it.

agreed but then there are people (me) who want to go with these, but will be doing some form of LPFP, Plungers, Stock Injectors, and only the Flex Fuel Lines/Sensor, and maybe WMI if I ever figure out the kit/setup I want to run being W2A

I know I wont see those numbers, but something close-ish on E50 blending

I am talking to John about his on FB, so I'm still deciding if it's worth it over my S8 stockers on E25. I already have LP lines and as thinking about grabbing the 034 plungers kit. My concern is what else will I need? Will the stock cats hold? I'm NOT looking for DP's and having to deal with readiness for inspections.

Jack Jones says the stock DPs will hold. IMO, unless you are going high-hp, DPs are overrated based on their marginal benefits.

This is what ive been wondering too. I love downpipes I love the sound and I actually do like the smell but if they are not an issue or leaving much power on the table I rather put the money on other mods and do that last, it’s hard to find the direct answer from researching as most modded people throw the downpipes on. I do want high hp on my stage 3 setup but not going for anything over 680lb ft for now on the oem clutch. Should I keep the stock downpipes on my setup? More details in my signature

Really all personal preference. If you are looking to get the most out of your upgrades, your answer would lean towards, yes you should swap them. You would get a better answer from a respected and capable tuner of these engines, but they would very likely want to see logs to help determine how the car is performing with your particular set-up. It has been said, that with your current E content levels, on stock DPs and RS7 snails, you could be hurting those OEM cats. I will be going stage3 with very similar set-up as you - minus ethanol - and will be staying with the stock DPs with zero worries personally

Man I know how science can be weird at times, but the amount of bends with the stock downpipes (and cats) just blows me away still that they handle anything over stock in terms of temps and power. 3.0T’s blow cats on a stock levels and they have a more direct air flow path to have exhaust move through than the 4.0T does with its crossover lay out and sharp turn after the cat. I can’t imagine the cat material and design is any different between the two platforms maybe with with the B8.5 4.2 as well if one wanted to stretch it out. Maybe I should do a little more reading before commenting but I always thought turbos liked bigger exhaust than smaller up to a point. N/A and blower cars are a little different. Granted I know the turbos aren’t exactly humongous either on these cars.

Solid advice. I think I will definitely add them. As far as e85 I think it’s really the best bang for your buck mod on this platform. For what you pay and the gains you get not to mention the car runs much better and cleaner on it, but it’s not readily available to everyone so I understand why some people don’t. These cars are so neutered on 91 octane, 93 isn’t too bad though

I agree with that logic too especially coming from 3.0t but as some people have pointed out to me, rs7 has the same cats and they tend to do fine on stage 1 levels long term so it’s very well possible that they’re stronger than the 3.0t cats
