Toward the end he actually shows how big the new machined passage is from the manifold through to the wastegate. Seriously impressive compared to any of the options I have seen up this point from a flow perspective.

Agreed on the single though. If I could do it all over again, I'd get a SpeedTech kit. Great manifold paired with a tested and true turbo by the company of your choice.

Guys,

My front OEM turbo took a dump and I bought the VIV stainless 19T turbos which are being installed as we speak.
To keep the community informed, I will post my findings here if permitted (this is a DAW thread), so OP, please see if appropriate.

In any case, i suspect that these turbo's all come from the same build house so....

[hamitaw]

Just to update the crowd following this:

Car was on the lift to start the swap, then I realized my downpipes were OEM decatted, while I understood it already had aftermarkets put in by PO.

No biggie, might have missed that when buying the car 2 yrs ago, but it didnt make sense to start the swap and do DP's later on.
So I bought 2nd hand VRSF (@jonerik26, thx man!) and they just arrived (Im in South America).

So bringing the car later this PM to my tech and having it all bolted in.
Hopefully will get it back this weekend and start the custom mapping.

Question (also sent to my tuner, but no response yet): would I need supplemental fueling to get all out of these puppies?
I currently have Snow stage 2.5 meth in the charge pipe, which I spray 50/50 for just cooling.

Do you have E85 access?

No E85 here unfortunately, and while we are at it, our pump is piss poor 89 oct

I have ordered 2 maps at my tuner, pump gas and unleaded racegas (Renegade HR103 oct. https://renegaderacefuel.com/product...ade-race-fuel/

You might want to consider direct port meth.

That’s an option but I don’t like keeping tabs on a second tank and depending on a second pump.
I would much rather do PI from the lp fuel line or do overdrive hpfp.
Seems less headache, but then I’m just injecting (the same) extra fuel. Might not need that on pump gas.
But yeah, I’ve decided in running the turbos in, getting tune dialed and then see what it would need for road use and the occasional drag event.

Pics of swap to follow

If just running pump you should be fine and likely not need PI.

My meth tank has a fuel level sensor. It goes on well before it runs dry and takes all of 1 minute to fill up. Meth gives you so much more headroom over pump.

Which pump do you run?
Havent read up much positive reviews on the snow, but for cooling, I am not worried if it fails or drops pressure

You have a plate or full mani?

[hamitaw]

Pics as promised.
We also noticed a beginning leak coming from the back of engine, so I bought a main rear crank seal while we are in there....

And yeah, RHD is a PITA!!!!!

If I was to start over I think I would go single though.

I would guess they'll make more power considering the turbine housings and manifolds are larger.

No need to guess, they will make more power but how much is the question.
I am also curious to see how fast the spool is.

Some update pics, heading over later today...

Which one is "they"?
The DAW?

I will surely post up my findings and logs once car is running

Yes he's talking about the DAW Flow Max's

A log with the fuel type, if you are custom tuned what revision you are would be great.

I am surprised I have gotten two solid seasons of racing out of my DAW 19T's.

Yep, thanks!

Why are you surprised?

I beat on them pretty hard. Between 1/2 mile and 1/4 miles races, then are at 25psi a lot of the time.
I do make sure the oil is up to temp and I change it often but for the price I did not expect to get much out of them.

I run a full aquamist HS4 setup and howerton twin meth tank w/ baffling. It's not cheap but it comes with EVERYTHING to inject meth safely such as an FAV as an example and no compression fittings. The gauge is pretty cool as well. I inject around 1300CC into my CP. If you install things smartly, meth can be VERY safe and VERY reliable.

I would switch to Direct port meth with an aftermarket manifold but I decided to go full E85 and I will keep the meth injection in the CP just because why not. A meth plate works fine mind you, I just prefer a tapered metal log style intake manifold.

[hamitaw]

Update: had several revisions on my pump gas tune (shitty 89 oct) and made 434hp and 373 ft lbs on 21psi on these turbos (edit: actually 19 peak looking at the log).

Meth injection installed, but did not activate it during runs, only plan on using it as a cooler.

I requested a conservative tune because of shitty inconsistent gas here and temps roaring into 30C during the day.

Torque build up is also quite conservative, so no instant boost on low rpms, saving rods etc.

I also have a racegas (102oct) tune booked, so that will be my kill map for the 1/4 mile.

It seems these snails will need PI or aux fueling to get the most out of them, but until now, I'm happy (and not breaking other stuff).

Awaiting green light from my tuner to post up logs and dyno sheets (I'm not there to start keyboard wars).

Dragy times to follow......

89 Oct crap fuel must be a big limiter,

Let us know how long the VIV turbos last.

This is my current setup. Direct Port E85 with a single 630 ml/min nozzle in the charge pipe with some bs boost juice. It likes the extra intake cooling and it's just enough for intake cooling.
