Bullseye Turbine Housing vs. PTE

[1fast97gsx]

The T350 wheel is what Turbonetics calls a Stage V. That's their nomenclature, so you won't find it on the Precision website

where did you find out that information? That would be great if this would fit my turbo ... just want to be sure before I buy. Thanks.

ive got the answer two which housing to go with between the two, ive ran both in the last couple months, vtrim bullseye turbine turbo, held solid boost at 21, pte 50 trim turbo boost creeped 3 lbs even with o2 dump, pte 50 trim with a new bullseye turbine housing and got rid of most of creep, mabey only a lb of creep mostly pretty solid. and also i think it spools little faster now too. full boost 3rd gear can be before 4000 rpm

I just put on a Bullseye turbo to4b with the big wheels and the only problem I had right away was the wastegate arm wasnt tight enough, so it Didnt reach full boost 10psi till 5000, then I tighten'd the arm and now im at full boost around 4500 rpm Im gonna go Tighten it alot more to see what happens.. So far im really happy with the turbo and the guys at Bullseye

So far the turbo has lasted much longer than the PTE turbo's I have ran

I've been having the same problem with the spool-up being really slow. I've tried tightening the arm, but its still not where I want it to be. I think the spring just may not be tight enough for anything, because that arm is REALLY REALLY tight on the flapper lever. I may try messing with timing around 3500 and 4000 rpm (dsmlink) to help get the spool-up issue to an acceptable level. Otherwise, the housing and turbo both kick ass and I'm very happy with it

I agree with you G, this turbo does kick ass, and as far as spool up, ,its all in the timing and tuning with this turbo. I am running 20 psi now and there is no boost creep and it holds strong til red line.

Very true! I just witnessed this first hand, myself. I logged a run with dsmlink with timing zeroed out. I got full bost at about ~4400 rpm. After adding 2 degrees advance on the link at 3500, 4000, and 4500, I got full boost at just a tad over 4100 rpm! I need to adjust the actuator arm a little more, and then I think it'll be just right at around 3800rpm at full boost.

Well, I am tuning with a Maft-T and AFC-2 and a Logger. My trims are really close to 100% on low,mid,high. I would like to get DSMLink cause I here soo much about it and how easy it is to tune. When I adjusted my WG arm I turned it 4 times to make it tighter and I seen it hit full boost alittle quicker and higher boost also, cause it must have been too loose and would not let me boost over 15 psi. Well keep us informed on how well it goes man.
