Nator SoCal Wetting your bitches vages one Twin Turbo Build at a time

[NJSPEED3]

Why would u run k04s, and not a gt2871's?

its going to smoke always, also Im sure you realize that both of your turbos currently need to be clocked down for the oil drain.

I applaude your outside the box build, but I highly stress rethinking your turbo choice.

[bmylez]

I forget if you mentioned it, but run some .070" oil restrictor bolts for oil feed. You will greatly decrease chances of oil seal failure/smoking.

Terrible idea. The pics are gold.

I appricate the input. I will be using 12x1mm female to female 4an unions with a .065 restrictor on each turbo. Obviously the cartridges on the turbos arent clocked yet. As you can tell they aren't even bolted on fully. They are just there for the mock up. The turbos were used because I had them already. I can always upgrade to a b&r or even to a 2871 in the feature. Keep in mind I'm not trying to break land speed rechords. This is my daily driver.

Thanks for your input. You seem to know what your talking about brownie. What do you recommend?

[JLuth]

Sounds fun! But I have a question because I don't know crap about twin turbo set ups, but if you are looking for faster spool with two turbos than you get with one? and you said that two cylinders are going to spool each turbo... So I guess it doesn't make sense to me that you can spool a k04 with two cylinders faster than four cylinders. Granted there are two turbos but pressure is pressure. Now you have more pipe and more friction/turbulence to interrupt. Correct me if I'm wrong...

Don't get me wrong, i love the idea and I'm jealous as hell, but I just hope it works out for you like you want it. Just speculating.

6 cylinders...

It's the weight of the shaft and turbines that is the problem there. You just doubled the weight the exaust has to spin.

Understood. In reference to faster spool I was referring to the spool rate of a 3076 not an individual k04.

[captain slow]

Hmm. I think its cool you're trying this and the fab work looks fantastic but I would rather see you do sequential turbo rather then parallel. Either way good luck. Hope it works. Gonna be unique for sure.

I promise my next build will be sequential.. Lol I have a spare K03s lying around that could prob Be used in a sequential set up.

Your a boss, can't wait to get to San Diego, that is all

Not a Speed!

Its still a turbo 4, I think that was his point.

[taf0422]

Can wait to see how this turns out.

Subbed for later viewage!!

[kmac]

He has enough cyl volume to spool the turbos . The problem is di egts are a lot lower than normal pi cars so u don't get the latent heat or expansion nearly as much. He should still be able to spool fine. It should hall ass . There's only one way to tell us to do it. I commend your effort and sub'd for the out come and win. If u ever need any help let me know.

[bmylez]

Kevin, do you have evidence that DI egt is lower? I could have sworn everywhere else I read, DI egt is higher???

[spnkr21]

For real
I hit 1800deg at wot.
I know there's a Big difference between NA and FI.
But turbo port injection to DI there probably isn't a big difference.

[rtabagaboy]

What you say to a sequential exhaust system with a parallel intake blow through system like ya got. I was toying with this notion for a while, but never had the motivation to follow through. Good luck. Lets see results!

Twin K04s should move more than enough air. If B5 S4 guys with 2.7L of displacement hardly run out of breath you shouldn't have a problem. If they aren't spooling quickly enough which I doubt will be an issue there are always twin K03s.

yes I have an egt in the car . And my temps under wot r low compared to pi cars. Plus the more adv the timing is the lower the egts will be . Even though internal cyl temp r higher the egt is lower due to more burn taking place in the block and not your exhaust runners.

[spnkr21]

What do you see for temps?

[kmac]

I'll do a pull this week and get a video, but I don't think I've ever seen over high 1400 unless I retard the timing tremendously for spool.

[spnkr21]

Aren't you spraying meth/water?
That brings you're exhaust down doesn't it?
So Not a really good comparison for di egts. I see 1750 after a wot run. No h2O/meth.

[HXC LOL]

Damn, this build is looking pretty boss so far.

In for results

thats looking pretty crazy man, in for results. =)

What do you think Alex? I am getting closer to needing those magic little maps of yours. @Lex

[Rokusek]

sub'd for out come...

@keefover shit looks fucking sick!!! good work man

[SofaKingAwesome]

hurry the fuck up and finish

[keefover]

Fab work is done boys. @Derigo and I will be pulling the motor on monday. Does anyone have any tips that helped along the way that the WSM neglects to mention?

[keefover]

My shit is going to fucking scream!!!!!

[dooderek]

ill be there

[boostyms3]

Where in sd are u I wanna check it

[SleeperHatch]

I shall be there when this finally gets to dereks pad

[dooderek]

upper san diego oceanside/carlsbad area

[cld12pk2go]

I am guessing it should spool around 4200 RPMs +/- 300 from a low RPM 4th gear roll...

Those turbos will support around 600whp, which is more than insane...

Interesting build with excellent fab...

[Mistersix]

Very cool. Nice to see something different. Subbin.
