AbsurdFlow + GT2871R + TiAL pornography
 

Figured I should explain my new signature.

The development of my track slut has reached the point where I am using every single bit of the 220whp I have - which means I can use more. With chronic hardware issues plaguing myself and a bunch of others who track their cars, I started looking into alternatives... and the whole thing sort of ballooned out of control.

MANIFOLD/DP/WG:
Manifold and DP will be fabbed by TurboTim. With my horsepower and response goals, a tubular manifold was a no-brainer, and his shit is the best. 100% stainless steel, with a TiAL V-band outlet.

WG will be TiAL's new MVS wastegate, which is tiny and badass. Honey, Who Shrunk the V44, or something similar.

Attachment 205323

The biggest advantage, aside from the lack of flanges, is the sheer size of this thing. It's friggin tiny, something like 3.5" tall from TiAL.

DP will be from Tim, SS with a straight exit under the car. EWG will be dumped next to it, so I can recirc them later and add a catback to run Laguna if I need to.

TURBO:
Choice here was obvious. I wanted the biggest turbo that still provided acceptable response. I've driven a 3076 on another car and didn't like it at all, so I went with a mid-range (52-trim) 2871R. Not exactly an off-the-wall setup, but the real centerpiece of the new setup will be the extensive use of V-bands.

Attachment 205324

Aside from the flange at the head, there are no flanges in this setup. None. No more studs to drill/replace, nothing to tighten.

Power goals are lofty. Out of the gate, I want to see what the torque capacity of a 6-puck ACT HD is. It's rated at 300ft.lbs or so. I will be tuning the car on 100 octane, and using a Devil's Own Basic setup on track to keep intake temps down. I won't tune on the WI, which negates the need for failsafes in the system - it's purely a safety margin. Once I slip the ACT HD, I will probably be doing a 949Racing twin-disc for both weight and capacity. On 100 octane at 22-23psi, I should be able to see power levels in the mid to high 300whp range, with torque near there. It may take an intake manifold as well to see those numbers, and I've started looking into that already.

I will post photos in this thread as the new setup comes together.

nice! did you see Newb's dyno plot I just posted? 1.6L at 8.8:1 with a 2861 at 16psi.

Sounds like a very sick setup. I know I love the way my Absurdflow works with my 2560. I was thinking of going to the 2871 but don't really need/want all that power. Good job dude.

Great project!
Cost estimate on parts involved?

Is it wrong that I'm sexually aroused by this?

Not at all, I know I am.

^^ yeah it would ruin the fun but hot damn....that is a nice setup.

Got it:

Nice! Congrats on the new setup plans! FWIW, I absolutely love my 2871!

I'm tuned in....keep us updated!!

Sav,
Wow. I look forward to seeing this come together.

Are you building this with a certain race series in mind or just track fun?

I foresee Hustler spending alot of money soon....

Chris

The car is being built with pure speed in mind, but I can put a dashboard and center console back in place and it would be legal for RTA's Modified class.

this is gonna be pretty.

And I was thinking you were gonna go V8. This looks like its gonna be tits on bull! I cant wait to see how it turns out :bigtu:

andrew, you can suck a bag of dicks.

this is pretty much the setup I'd be running if I were to re-do everything (well, except I'd run a full exhaust)

I think the 2871 is a highly underrated turbo for the miata. I would swap my coldside out today if it wasn't cost prohibitive.





i take back the dicks thing. that setup is going to be friggin AWESOME.


nws down here.

if you have to ask, you can't afford it.



^not being sarcastic

I was wondering when you were going to reveal this Andrew, congrats again! Now you won't be in the pits every other lap reconnecting your shit. j/k

Sounds great! But what about bracing the turbo? IIRC Corky used some measurements of how the turbo was moving when hot vs cold to create the brace for his S4 manifold and how it should move, and there are still people complaining that the maniold cracked.
With the much tougher racetrack environment how are you going to prevent the tubular manifold cracking? Tracking the turbo movement and building the proper bracing yourself?

Best of luck Sav, can't wait to see the finished product!!!

Time trials in your future? What other mods are planned to support that power? Suspension you have handled. Brakes + rear end?

Nice

You are my hero Savington, but I'm extremely jealous.

wow.....cant wait for pictures/video's

Very nice. I think the 2871 is great. I would get one again. Well, actually I guess I will be one way or the other :)

Excellent choices, 2871 & AbsurdFlow, and a built motor I assume. Color me green.

Is that green with envy or as in cash since he's buying parts from you!?! LOL

With his built motor he's shooting for the power levels you have on a stock one! How much use and abuse are you giving that motor at that power level? Any feelings or insights into why it's held together so well? I know. Tune, tune, tune....

It's turned into a time trials car, yeah. NASA TTU, Miata Challenge Unlimited, probably some RTA Modified as well. Suspension is covered, but I'm not thrilled with how the RACEs handle high-speed bumps, so I will be upgrading those in the future. Either revalving or replacing, not sure yet. Brakes are Corrado fronts and stock rears with Carbotechs, a Wilwood prop valve, and ducting, but I may end up doing Wilwood calipers in front since I am starting to hit the limits of the stock one-piston calipers, just in terms of pad wear. Drivetrain is covered, 6-speed and a 4.10 Torsen. I may end up with a 3.9 if I find myself running out of gear, but I can also just rev the motor harder.

Certainly not cash.

I don't track my car so it doesn't see the abuse his will. He's buidling in some headroom, I'm at the cusp of exploding. I do drive it pretty hard on the street though. Other than tune, the weight of the car has a lot to do with things like the trans and diff not breaking. I also don't drink it like a 17 yr old. I don't do high rev drops. If someone wants to race me off the line I'll ease into it just to get their hopes up and then peace.

You've definetly bit the track bug hard. You seem to be humping it into submission with all the new stuff though. Wheel to wheel can't be too far off in your future either.

I've gotta get down to a CA Miata track day. I'm hoping to make it down this summer/fall for a weekend. With my crappy skill and DD car all the CA hardcore cars will eat my lunch but it'll give me something to build towards.

savington is a ------ and I wish AIDS upon him. Come to Texas and get charged up, like a bitch.

Wow, I cant wait to see this come together. And I know there will be videos of said setup destroying the track. One thing though, did you decide against buying a vette?

Hustler, keep your pos-rod out of this thread. :makeout:

...and out of Savington.

July or August.

"Savington does Dallas"

Not to mention the laundry list of other things currently being done to the car.

Such as shortening the ECU wires in order to save weight.

And another random picture from a few days ago, lol.
Attachment 205301

Wow, thats a little extreme. What kind of weight savings expected? Couldn't be much, 2 or 3 pounds?

I figure the rewiring has been worth around 20lbs between wire, brackets, relays, etc.

To hell w/ the weight savings, it would be nice to have all my wiring JUST long enough to do what it needs to do, and not loop around shit and be all messy and in my way.

I hate wiring. ARRRRRGH!!

Props man, I envy your willingness to hack your car.

This will be an amazing machine. The End.

I think Sav's getting a deal actually ;) There's a very good reason Sav's only sending me the turbine housing to fab up the manifold and DP. If he sent everything I probably wouldn't return it without "testing" it first.

Fun stuff. I'm glad I'm a part of it. Thanks for the trust Sav.

Tim you should definately keep all paperwork on that manifold and dp for the gt2871. Im going to end up with it evenually. Ill be a mock-up sav's car except slower and less reliable lol.

What internals are u planning to run, JE/weisco, crower/carillo or supertech?

I'll say this for anyone thinking about hiring Tim .... it's not cheap, but ALL of us who use his products are happy!

A much less expensive route would be a mild steel manifold (like Artie's and paul's) and an internal gate 2871. Weir's SS flanges are a bunch more than his mild flanges, and the tial flanges + clamps are also a lot more, plus you're adding an external gate & the plumbing/fab time for that, etc...

Actually I'm having a slightly difficult time getting Jes' duals where they should be, but thanks Evan :)

But mine's ceramic coated. SS still more expensive than the mild steel with coating?

I'm considering the switch too. Do it once, do it right, do it with SS parts and v-bands.

Any thoughts strength and ductile qualities of mild steel vs SS? I PM'd you about a stainless manifold, but I could also do the mild steel manipheould and coat it with that white shit.

Will I be able to get a wrench on the lower, center bolt on the manifold/head?

Any track people using this set-up with success? I'm talking about the men who are chasing down lap times...not the fagmo's out for a sunday drive.

Oh yeah I forgot about that shiny bling you got. Ceramic coating mild steel is probably still more than stainless, yes. Weir's SS flange, head and T2, was $100 & $40, his mild flanges were $22 & $10. So it's about $110 more for stainless (raw material for weld ells is actually cheaper for stainless by a few dollars). Ceramic coating is more than 110, especially when you include the turbine housing like you did Mr. Party.

No, no one yet has used one of my manifolds on a roadcourse.

I have thoughts but not hard evidence on the pros/cons between mild & stainless. My first crazy "ramhorn" manifold on my car was stainless and that was fine, pretty "buzzy" though but I think that was due to the length than the material. 304SS does grow more when than mild steel, that's for sure. Note BEGI and their fancy bracketry for their ss tubular manifold.

Sav considered mild, but ultimately the TiAL flanges only come in stainless. Not technically a big deal to weld stainless to mild supposedly with the right wire (which I bought a while ago but never opened) but he figured might as well make it all stainless. He's going with thick schedule 40 stuff too.

You can get to all the head bolts very easily. Your arm goes where the power steering used to go. That is unless I route the EWG in there (between turbo & block), not sure yet.

See the fun room on this pic of Artie's car:

Put the waste gate on the top so everyone can see it.

Bravo Andrew. Bravo.

Emilio: "damn it, even with my amazing grip Savington is faster than the OGK... I need boost!"
*Emilio installs Rotrex, enter 200+ whp in OGK*
Savington: "Oh I was just getting started..."
*Built motor + GT2871R = Emilio takes his place in Savington's rearview mirror again*

Interested in pictures as things develop. I'm looking for another tubular option. ;)

ha! I'd happily build this all again for a set of flat black 15x9's.

The barter system at work, lol.

They own your soul.

Slow progress, but progress:

how's this for badass: ATP had all this shit in stock.

Tim, by the time you read this they'll be on their way to you.

^^^^

sexy

All this shit is a TiAL housing and a wastegate? Still pretty badass.

I just ordered the same ewg to put on my ETD shorty. That housing looks money, I wish they made them for std t3 turbines.

Sweet! Just in time for my vacation. Don't send them to my house unless you want them sitting outside until I get back ;)

BTW, damn that looks like a big inlet. Hmmmm

Do they send you hardware for attaching that turbine, or do you reuse the garrett stuff? Doesn't affect me, just wondering.

is that like a 5" exhaust outlet?
