Well everyone else is sharing lately, so I'll add to the turbo fest as well.
Everything is all buttoned up just need to get it down to Chris at Banzai Racing for the tune.

 

Where did you get the To4Z from? Sure its not just a BB to4R with a bullet style antisurge compressor housing?

to be a proud member of gangsta rotaries you should know this

 

Thanks,
I 've been around the block more than once.

 

that's one nasty charge pipe.

 

Did you have chris do all the work on that. LOOKS AWESOME! I'm goin in next thursday do have some stuff done, is it still gonna be there?

 

Looks tight dude! Sweet, no clearance issues with the HKS shorty manifold? What size turbine A/R is that and what blanket? Can you please post results at 15lbs, if possible?

 

The TO4Z's i use and specify have no surge holes, these reduce spool rate, they reduce PR te tubo can produce, they reduce efficiency, they are bad news all round.

They were only ever created to increase map width when use with a small turbine and use on a small displacement engine that suffers from compressor surging under throttle at low RPM (too much boost pressure and not enough corresponding flow rate).

If you want more data from another field go onto supraforums.com and look at the anti surge delete they do for GT42 and GT47's ect & note the decreases in spool time and also inproved turbocharger performance (ultimate flow and also peak boost).

 

As far as I know that is 100% true about the " bullet " style ones, then again what ATP sells and what you have are two different turbos I believe..

 

nice I've been wondering what you've been up to, you going to the spring BBQ?

 

We built the engine and did some of the mods a few years ago, Finnicky installed this turbo over the winter because his last one self-destructed after a season at 20psi. We will be tuning today, the car will not be in the shop when you come in next week.

 

Bummer... Well hopefully there are some other nice ones in there to look at while my car cools down.

 

We tuned it today and surge holes or not it was FAST. Night and day difference from my last setup. As always Chris at Banzai Racing was awesome. I will try and dyno the car very soon. Low boost 15psi high 25 psi should be interesting to see what kinda numbers I get.

 

I thought I saw an hks twinpower, is that right? Also did you run meth/water injection with pump for 25psi?

 

Yes, it has a twin power and we were spraying water/meth for the 25psi tuning on 94 octane. The car spools very fast, we were seeing 25psi at 4200rpm and holding until redline

 

After 20psi it got interesting all the way till 25psi we started blowing off vacuum lines, and then a coupler let go. After the tune I drove it 3 hours home smiling all the way.

 

Its funny how things progress, with some form of extra injection.

I turn up to someone event now and look for things that will pop off its not sufficient to have vacum hoses on straight barbs especialy after they have been sitting for a while in a road car. Just becomes second nature when your running your street car around at 25, 30 or 36psi ! to find these failure points of connections that were never ever intended to see that much pressure over stock

seeing a customer smile when he experiences 20++psi is what its all about, i think any single turbo owner who does not run this boost at minimum should be banned?

 

wow Im gonna get banned for not running 20 psi haha
We in the UK **** ourselves if we run more then 1 BAR on a single

Finished the AQ WI installation on my T04Z Half bridge single install, flowing about 400cc of water scaled to my injector duty, pulled out a lot of fuel and running 17psi now the car is toooo fast for the road feels about 500rwhp will know when it hits the dynopack next week.

Will have to grow some ***** and venture into the 20psi zone so I wont get banned haha

 

^ thats great news

you will get used to the power & 20odd psi is where life begins, in fact make it a nice 1.5bar 22psi haha this is what i force all my end users on and they dont hear the end of it till they finaly turn it up.

Sounds like your reaching your limits of adhesion soon anyway, I know what that feels like in a half bridge T51 with water at 20.6psi its scary !!!

 

Banzai is working on a 2 bar setup for the car, but with the tires spinning at 110mph it will be interesting to say the least.

 

Congrats on the great setup... We will see how my T04Z setup runs on my Banzai Racing rebuild too

 

 

She goes on the dyno this Friday, so we will see. The plan is to run 94 octane w/ H20 injection for 16 psi and above.

 

Post Video of it, I want to hear that turbo spin

 

I would like to see the IAT #'s also
