Where are all the modded C5 RS6 at? 500awhp to 800awhp+?

[Corbett]

Glad it's up and running. You're on the Tial 880's or something like that correct? And fully open exhaust or high flow cats? C'mon you got to give us all the details! AMD tune, and it's manual correct? Handful of things bringing your whp up...

They are called tial 880s. Basically tial 770s are a 2871 wheel these are 2873. Not a huge difference. Also larger comp cover. Downpipes are 3” no cats. Straight pipe with a X and 2 resonators. Not that loud actually. Block was rebuilt with ie rods, coated stock pistons. Heads redone with ferrea valves. All custom hardline fuel lines. Completely redone wiring harness and wire tuck. Custom inlets for turbos. Stock exhaust manifolds ceramic coasted. Custom intake setup. Bunch of other stuff. Also custom geared trans now with longer 1/2 and billet input shaft.

Thanks for posting.
If you dont mind can you provide more details?
Do you happen to have the spec of the tials spec? more specifically exhaust wheel size? I cant seem to find this on google.
what intercooler are you using?
how much boost are you pushing?
are you using the stock Y (before the intake manifold)? or did you make a custom piece?

Well this looks like its already contradicting some people on here regarding the limit of the stock exhaust manifold.

There is lots of info on tial 770s which are basically the same thing.

im still using the sportec intercoolers unless we determine they are hurting flow or have too much pressure drop.

right now it’s on wastegate boost 20psi or so. Not sure what we will run in the end. Depends what the car likes.

stock bipipe from intercoolers to throttle body.

and yes the same guys saying the exhaust manifolds are a restriction are the same guys who said this car wasn’t fast before it went in for upgrade, even though it still the highest trapping 1/4 mile Rs6 in the USA 5 years later.

Awesome, appreciate the details, sounds great!

Yea im still having difficulty locating tial 770 spec. The only ones I found are questionable sources and it states:
Cold:
47mm
hot:
53.9mm
Is this correct?


sportec IC looks tiny, 270 x 270 x 64mm. Have you log your AIT? before meth and during meth inj?

what size nozzle are you spraying? and how many?
Is it progressive or consistent?
Also where is the placement?

I think with water/meth you can get away with a smaller intercooler(I've seen some run without IC). on my previous car my AIT would literally drop from 110 to 70 when it kicks on.

Have fun with E85, I was pushing 35psi on a daily and not a single issue
Well with the exception of having to visit the gas station almost twice a week. Awesome gas sucks for daily use.

Thanks for posting. Its great to finally find someone here that has some power mods.

Funny. Corbet is one of the few (count less than a handful) that have gone to the extreme end of revising engine internals, tranny, turbos, etc. As mentioned by a number of people in this thread, it takes $$$. What Corbet isn't sharing is that the extra 100hp he's citing vs. a number of members cars on here comes with some decent coin. If you have the wallet to pay, then you must really really want to play. I can get three times as much additional power out of my Turbo Buick than I can out of my Turbo Audi for the same $ and that says something. Hell you could buy an AMG as a spare that has more power for the amount you will pour in to modifying the Audi.

Will keep watching the forum to see how you and your wallet fair with things.

I mean if you're looking at 800awhp I don't see a non built engine handling that much power. Not even LS based engine can handle that in stock form, they too need internals and your looking at what 5-10k+ in "built" engine. (although I think truck engine had a record of 900? before it went boom)

I'm hoping at 600-650 would be fine with stock internals. The rest of the mods should be interesting, money wise. That part I would have no problem sharing, I'm counting out pretty much almost all bolt-on power mods as a no go. Cant say too much just yet but I think I have a few things in the works right now.

Besides if I remember correctly from the start of this thread, the consensus was I would need 15k for parts ALONE, to get 600+.
20k+ if manual.
Just need to hit a fraction of that and I'm golden.

Its a good thing tunning isnt a "part" because that's a big ticket item


eh the whole easy power thing is overrated. I think if your strictly track then yes go LS based. You cant beat the hp/$.

But if your dd or mostly street, hope you like all the wheel spin of that turbo buick at 600whp+.
Not to mention spinning all day unintentionally with just a bit of moisture/rain on the ground because of DR.
but hey to each their own, I just know I prefer something else now.

Did you have to modify the stock manifolds to bolt up to these turbos?
