Wouldnt it be awesome to own a twin turbo v10 Audi sedan?
The new model TT v8 s6’s are cool as hell and sound sweet, but this would sound so amazing i think.
v10 + turbo whistle= wet panties
lol
what do you guys think about the setup?
You may as well import a used RS6 V10TT engine if that’s what you’re shooting for. The Audi RS6 C6 is literally the car that you’re describing, and that way you wouldn’t have to Frankenstein the S6.
Im gonna try to do this as cheap as possible. wish i could do an rs6 swap, but going this route will be the cheapest since im into doing my own mechanic work and have a good idea of how to do this myself. only thing i would need is a dyno tune.
running a low boost rear mount setup shouldnt be too hard on this motor. especially if you have modded intake with more breathing room than a stock one. I removed the flaps on mine because they were broken.(audi should be replacing these intake for free due to piss poor engineering on all the s6/s8’s that suffered the dreaded intake runners problem).
Remote rear turbos have shown to be a disaster with poor results.
Looking into gutting the cats and getting a JHM tune would be much cheaper and get you well into the 12s. The fact that you have twin throttle bodies and then twin MAF units creates a nightmare and you end up with a shitty running car cobbled together. I would strongly suggest against it.
That’s my plan in 2023. Thank goodness for Canada’s 15 year import rules. Hopefully I can start looking in 2021 for one so be shipped here for 2023.

I’ve seen more than a couple Fox body Mustangs, Camaros and Corvettes with remote setups that were more than impressive. The only remote setups that I’ve seen that were disasters were the poorly thought out and frankensteined kludges that likely would’ve failed because of the builder’s poorly thought out and executed plans - likely they would’ve failed just as hard using traditional setups as well. There’s challenges running remote (air filter type and protection is one); the cold side piping is probably the easiest hurdle of remotes.
I wouldn’t discount remotes on an S6 - from a heat and packaging perspective it does make sense, but I don’t think it makes more sense than just running a supercharger up front where your biggest hurdle is IC piping and placement. Seems like a much easier problem to solve than remotes on this car IMHO. There’s also a well established engineering and development precedent on other Audi platforms going this route.
They want 16 or 17k for that supercharger for s6/s8. Lol not worth the 100+ HP . I’ll just buy a couple garret turbos and do my own piping. I won’t be going over 7-8 lbs boost on the streets. Drag strip I might push it to 15-20 and might blow it up but hey that’s cool I would love to do dished pistons, thinner rings, port and polish the top end.
Btw I’d even consider bigger displacement. I would love to know how much more displacement we could get while still being reliable.

Well keep in mind on the domestic cars there computers are simple the Audi computers are much more complicated. Most systems run MAFless and that’s fine for the domestic cars but in your Audi your MAF runs the TCU the ECU the traction control. Now if you don’t care about all of that then… your most likely beyond help…
Jon who has a kit for 17k… I Agree that’s a rip off. but keep in mind if you get any forced induction your not going too far over 100whp anyways.
I think the only way a big turbo or maybe promod vortech would make sense would be if you had the engine built with forged internals, etc. Same thing UGR does for the 5.2Ls in their cars. Their 1000-1400whp kits all seem to come with forged internals so I’m guessing that’s because the stock internals won’t make that power reliably. In an ideal world, we’d all have $100k to throw CountVohn or UGR to build our cars over 1k hp… but unfortunately that world isn’t a reality yet. If I ever hit the lotto (or do well in business), I’ll send my car to CountVohn to for a billet vortech, custom code, etc, etc… Someday lol
Countvohn with the vortech for the win. I just put the vortech on my S4… its the shit. really well done great mod.
Also guessing the 12.5:1 compression ratio has something to do with it, lol
Now that’s what I’m talkin about. Dig into the block, bore it 30 over, forged internals, dished pistons. It would be a fucking monster. But doing it yourself wouldn’t cost more than 10k. Going through an independent guy that knows his shit might cost 15k or more. I’m probably gonna do the rear turbo setup when I get more time. I’m thinking at least 550 hp and a little nos to go along with it. Dont wanna push it too hard.
I’m doing remote twin turbo.
Have two efr9180’s with divided housing, two waste Gates to act as quick spool valves, two nice waste Gates for gating. Biggest issue I see with the S8 is where to route the hot side piping towards either OEM turbo diesel intercoolers, or chargecoolers where the Original airboxes live.
I’ll probably end up diy’ing nice stainless 5-1 equal lengths because of how crappy my originals have become (the flexi joints are slowly breaking up and the studs need replacing)
Once the engine is out for major servicing like Greg did, it’ll be a small effort to make those. Might solve the hot side piping routing issue too, without the Cats.

I’m with you GRS6. Buy an RS6. The work is already done. Get a car that runs (and runs properly!) right away and probably spend less in the process. No downtime, no screwing around with custom tubes.
