I'll put it up as soon as its ready.

Post # 964.....
"I called SBR on the restrictor. It is 4AN and 7/16 inverted flare. The restrictor orfice is actually .045". A little too small for these CHRAs. "

that sounds like it's for a BB CHRA

 

[whitegst97]

So this restrictor is way to small for the BullsEye t04b?

 

[1029TSG]

I should think that would need to be drilled out to .080 or very close to it.

Yes, it's intended use is with BB turbos....

So this restrictor is way to small for the BullsEye t04b?

And yes it is way to small for journal bearing turbos like these.... It would eventually starve the turbo....

 

[whitegst97]

What size drill do you guys recommend we use to get it as close as possible to .80 as suggested by dave.

 

[99gst_racer]

David - Will your restrictor be mounted on the CHRA or the oil filter housing?

 

[1029TSG]

Drill bits come in all sizes, I think a more common size is .076 which will work.

 

[MaNGiNa24]

After 2 months with the turbo on, still no problems, and it's been doing awesome.

1029TSG: Please check your PMs.

 

[1029TSG]

Thanks, got your PM. Email me your address and we will send you a new flange.

Anyone had a similar problem, im not able to hold boost. Besides a 5k rpm spool up i set my boost to 15 and reach it with no prob, then starts to decline and eventually lands at around 12. Anyone have any experience, I'm using a Joe P boost controller and getting boost signal straight from the PCV nipple on the intake manifold. Also i have the problem of the oil burning, with restrictor and 1/2" return line. Any help would be greatly appreciated

Is the o2 housing ported to match the turbo's turbine housing? That alone could greatly affect spoolup. I'd also pressure test and check for any leaks.

 

[boostcreep]

Sh!T... I just bought the SBR restrictor. Now I'm pissed.....

 

[whitegst97]

Just drill the whole a little bigger, i did it to mine and it works perfectly.

Guys...all I have to say about this turbo is that it's amazing. I downsized from a DSM-Performance 60 Trim because I wanted something streetable and this turbo is absolutely sick. I didn't expect it to be so quick. To make a long story short, I went for a few runs with my buddies modded '05 STi (The President of the AKA Rally) and handed him his ass at 20psi, and I'm not perfectly tuned. I dont care what anyone says about huge turbos; do yourself a favor and get something that operates over a broad RPM range. My .60 pulled hard up top but didn't seem to hit the meat of it's power until around 5500rpm or so. I know for a fact that my car is faster with the V-Trim as 20psi comes extremely quick and holds perfectly to redline. If any of you have any doubts about this turbo, FORGET THEM. Thanks Dave.

 

[NOSLO2PT0]

Since we have NO idea how the other car was tuned, nor can we really respect a butt-dyno comparison, how about going and getting some actual #'s? Because 300whp will feel faster than 240whp. But if the turbo is supposed to be making 400whp, does that still make it a better turbo?

We all want #'s. Nothing more, nothing less. Advertisements don't mean squat without empirical data to back up the advertised claims.

 

[FutureGSXOwner]

Trust me dog, I plan on getting this thing dynotuned ASAP. The turbo has been in for a whole two days. I was just letting you guys know that this turbo is awesome. Trust my judgement until I can bring you guys some numbers. I'm on a stock 7-bolt with an AFC/Logger and the STi is dynotuned with intake, exhaust, manifold, external gate and 19psi. I couldn't beleive how responsive the T04b was. I expected much less.

 

[1029TSG]

Anytime, GSX. Just bring your video camera.

 

[whitegst97]

GSX, what kind of spoolup are you getting with this turbo?

 

[questhe]

Hey, Dave, Just to clarify,

In my case I have the oil from the filter housing, and no restrictor.
I am getting no smoke, and no problems.

Still want me to get a restrictor?

Also, wouldn't getting the oil from the head be another way to reduce oil pressure to the turbo?

 

[sweet97]

Since my Bullseye turbine/center section is oil cooled only I go from the oil filter housing which is freshly cleaned oil at twice the pressure of the dirty head oil.
I say if no smoke then keep it like it is. How about it Dave? Mark

 

[1029TSG]

You got it. The best place is to tap in to the filter housing, if by some slim chance you have too much oil pressure due to engine mods then you would need a restrictor.

 

[steel_3d]

When you say tap, you don't mean tap a new hole, the feed line fitting fits into an existing hole on the oil filter housing, right? Sorry I haven't gotten down there yet to check things out.

Anyone had any problems with the new style oil drain line with the angled flange and no angled fitting? Seems like it'll be bent pretty good.

 

[1029TSG]

No, just pull the top plug on the filter housing and the fitting in the feed kit will replace it. Some of the drains from our supplier went out a half inch too short and in certain applications you may not get it to fit. If so, we will be more than happy to replace it or send you a fitting to extend it.

 

[whitegst97]

Or you could just add a piece of coolant hose 3/4" OD of about 1" in length and that should help with the fitting problem.
