Bullseye Stage 3 Housing:looking Inside After Almost A Year!

[diamondstargsx]

i saw this after i pulled the comp housing and center section apart from the bullseye housing i bought allmost a year ago.my scm 50 only has about seven months on it after a rebuild from them.has anyone had this happen or seen this?it is like really thin in this area so i can see what the heat does to it after time since the exhaust gasses pass right down over the top of it.

I had that on my HX35. I called and asked about it and it is just like you said. That really thin piece of metal can't take the heat so it cracks. I just took a dremel to that little area and have not had any problems since.

bullseye also said that they have changed something.. ( I can't remember if it is the tooling or the machining) to take care of this little cracking.

It looks as if your EGT's are a bit higher than the recommended safe level and considering the red ring residue found around the lip where the bearing housing sits it looks like you've been running some octane booster. You may try running actual race gas to eliminate any detonation which would also cause this cracking. Since you have it off the car please send it to us so we can make the repairs for you.

diamondstargsx, have you had any other engine related issues in which this comment would make sense.....?

It looks as if your EGT's are a bit higher than the recommended safe level....

What is the "recommended safe level" for Bullseye products? I can't find anything specified on the Bullseye website.

 

[1029TSG]

I was referring to the recommended safe tuning level for your engine and turbocharger which is around 1600 F.

I too just pulled off my bullseye turbing housing yesterday and notice almost the same thing! Mine isn't as bad as your's but it is still cracked a bit right there where the casting is thin. Also, my turbo was on for approx 5 months w/ this housing, Its a T-netics 50trim. Since, mine is newer, I assume they have not changed the casting procedure yet, although I am going to dremel that small peice away so nothing bad could happen to my turbo. I will try to take pics of mine tonight and post them.

 

[Coup D E'Tat]

I can't wait to replace mine

Still undecided as to what is going on next, though.

 

[ISUJakey]

I wonder if FP housings crack like that. It's a good thing for the "No Hassle" Extended Warrranty.

 

[1029TSG]

The tongue area on our earlier versions were machined a little too thin. If any of you are having an issue with this please contact us directly, we will be more than happy to fix it for you.

 

[Coup D E'Tat]

Do you guys make anything bolton bigger in size (AR) ?

 

[1029TSG]

Not yet, we have something in the .70 range planned for some time next year.

thanks for the repair offer that i will box up and ship it out.i have never used octane booster only race gas at the track.my egt"s have never gone above 800c on the gauge and it was tuned at 20 psi on pump with 20 deg of timing and around two to five counts of knock.i like the turbine housing but i really did not like the looks of this but since its an old cast than its brought to attention that the problem has allready been fixed,great!

800* Celcius is equal to 1472* Farenheit, which is not too hot by any means.

I was told to replace a turbine housing with this very problem by BEN @ AGP and Dave from Bullseye agreed with Ben's assessment. That was a $200. lie. I have been 1 of Bullseye's biggest supporters but I've about had it. I still have the housing here as I asked for it back. Anyone want a $200. paperweight? I guess if guys can use a dremmel to remove the thin area this could be used, Mark

 

[ITSME4G63]

i guess from the reads you should just take a dremel to it and eliminate that thing piece to prevent future trouble. Plus if they changed anything, its the casting forming itself, or unless, the tooing for their machinies eliminates that thin piece by just machining it out when theyre made.

1. I paid $200. to have one like this replaced, apparently it didn't need replacing.
2. I have some physical limitations that make turbo removal difficult not to mention the need for new gaskets, another $30.+ for the good EVO exhaust mani to turbo and the nice thick 2.625(2.75") o2 to turbine gasket.
3. I have had 4 Bullseye turbines and have never made the HP I should and cannot find anyone with dyno runs showing anything over 380whp. I should be way over that and the best et is 11.80 and best trap was 122mph. Nice but a second off.
4. I have been one of Bullseye's biggest fans and personally like Dave Hall but patience is wearing thin now. A larger turbine would be more appropriate for my Holset in my uneducated opinion. Mark
PS: The specs for the Holset wheels used cannot br found yet but I am told they are garret wheels.

You ever told you they are Garrett wheels are completely wrong. Holset uses Holset wheels. Just like Mitsubishi uses their own wheels.

You keep swapping out parts like cams, intakes, and turbos, wondering why you're not making enough power. At some point, you're going to have to stop and realize the parts aren't your problem. You're still running without a datalogger and on a chip that's giving you fixed parameters such as timing. The Bullseye housing is a hybrid bolt-on, sure it's a compromise over going full Garrett, but it also allows you to bolt it up without fabbing anything. It also flows enough for most people to make the power they want. AGP has used their housings for years and has made well over 380whp with them.

Carl's HX40 has already gone 11.5 @ 127 in a full weight car with not much tuning and low boost. That works out to easily 450+ WHP at only 28psi. Don't forget that people have trapped 140+ MPH on Reds, which use an 8cm Mitsu housing. I'd guess that thing flows less than the Bullseye housing.

We've all been down the road of being unsatisfied with our performance and sometimes we start to blame our combination, but the reality is that it's all about tuning. If I'd known 5 years ago what I know now, I could've saved myself alot of money buying parts I didn't really need to reach the goals I'd set.

 

[sweet97]

Steve you believe the Bullseye turbine flows more than the FP Red? Yes I have changed a lot of parts. My last 3 turbo's have been Bullseye's. I contacted a fellow from NABR tuning with my exact archaic tools. 11.0 at 131. He did have the benefit of a dyno. He also said he felt the Bullseye turbine choked off 50HP. Like I said I have been a BIG supporter of the Bullseye turbine but am having my doubts. Then the vendor I have bought from tells me my turbine needs replacing and I find this post where it seems the volute gets very thin at the end and should be ground away. The one guy who responded about his Bullseye 57trim said power went down with boost on the dyno.
I'm sorry but investing $700.+ in DSMlink with what I have read recently is hard to swallow. Bullseye is not very popular on NABR. I am not very popular on NABR, don't like their style.
My tuning can't be that bad to be running EVO 16G times and traps with my mods. I'd like to find a shop to dyno my car without requiring me to buy products before tuning. Innovative tuning in Buffalo NY wants me to buy link and then they will do 2-3 hours of "street" tuning at $65./hour.
I'm not giving up yet and I told you I was getting a laptop and TMO soon. I am not computer literate and no one near me has offered to help tune the car.
I am beginning to question the Bullseye turbine and would like to see some dyno info like SBR is running. They are supposed to be doing an HX-40. 11.0 at 131 on a MAF-T and AFR adjustments. It seems posible. I'll keep at it. Now I need to pull and disassemble the turbo to possibly make mods to the turbine so it doesn't destroy the turbine wheel.
Bullseye nor their vendors can give me specs on the wheels used in my turbo, frustrating. Read my mods. Seems like a second and 10-12 mph is missing. Anyone(vendor) want to guarantee that improvement with the addition of link? Thanks, Mark

Mark,
I have told you time and time again that the issues you are experiencing were not due to the turbine housing. And I have been correct so far, you found many problems that have contributed to the issues you experienced. So I can't believe you are still pointing fingers at the housing. You haven't done any tuning on the car since you fixed all of the other problems you had with your car last year. I have been patient and given you all the things you needed to fix and you have fixed most of them except engine management. Give the turbo the proper set up and it will give you great results, so please don't bad mouth the product when your car is the problem.

For example in another thread you blamed the turbo for overboosting and surge but you didn't even have a line going to the waste gate actuator. I think you are a nice guy but you don't know your way around a turbo car. And you push people away with your unneccessary and untrue observations and comments.

By the way, I believe you have a 2.362 inducer, and a 3.328 exducer on the compressor wheel. But you could take the turbo apart and verify those measurements if you choose. It's not a secret......

 

[sweet97]

It's the Hot side I would like the specs for. Thanks, Mark
PS: Did I read it right about the RED? Mark

You know I am DISABLED and cannot just remove the turbo and disassemble it to take measurements that the vendors should have in their files. Then I would also need new gaskets for another $40. with shipping or chance reusing the old ones. HX-35 hot wheel specs too please. I guess you can take one of your HX-35's apart and measure the wheel easier than me or do you order them on a per sale basis and have them drop shipped from BUllseye?

Here's a pic of a 7cm next to a Bullseye. Granted, the 8cm is slightly larger, but it's still a non-symmetrical volute design. The Bullseye is a symmetrical volute with a more Garrett-style scroll design. If you put a Red in a Bullseye housing that's made for a TD06H wheel, I'd bet it would gain some power.

Thanks Steve. My only concern is to be sure I have he possibility to make the power my motor should make with the bullseye turbine. I would not want to make the "link" investment to find the turine had "considerable" restiction, which I have read on NARR archives. I have been on of bullseye's biggest supporters. I belive my mods should yield a high 10 sec. run a 125+MPH.
I am trying to get the laptop and TMO today. I need to get comfortable with the thing. I will get link when I am more sure of myself. I LIKE the turbine, just concerned it could the that restriction I have read about. It is the internal VOLUTE that is supposedly the issue.
Now do I need to pull an "dremmel" the turbine? The $200. I did not need to spend but that is AGP, not Dave. I am stuck with his Holet and am going to give it my best. Thanks for the support! Mark
