t04b(v-trim) Bolt on Discussion

[khendriksma1]

I just received my new T04B "B-52" from The Speed Factor/Bullseye Power today. It looks like it will be quite a jump in power from my T-28. Anyway, while looking at it closely I noticed a couple of things that I was wondering if anyone else had noticed with they T04B's. I pulled the cotter pin off the wastegate arm and if I move the arm manually, it seems to "stick" a bit in the open position. How much force the actuator actually give he arm when it opens? Do you think it would ever get stuck that way? I also noticed that if I pinch the nut on the end of either (both) the compressor and turbine wheels, it seems that there is more play than there should be. It doesn't contact the housing but what is going to happen once it wears a little? The compressor wheel on my T-28 with 15,000 miles on it felt like it had less play than this one does and this one is brand new. I plan on contacting either Martin or Dave about this but I was just wondering if anyone else had experienced something like this.

A little up and down play is ok, that is the oil clearance. But watch out for back and forth clearance, that is thrust bearing wear and is no good.

When turbochargers are assembled at the factory they use a very thin lubricant. This thin lubricant will allow this up and down play that you noticed. Once you send your 10W-30 through there it will "tighten" up to what your T-25 feels like.

 

[khendriksma1]

OK, so what about the wastegate arm catching? I cam open the wastegate arm on my T-28 a full 90* and it doesn't catch anywhere. With this one, the wastegate only opens to about a 45* angle and the arm catches against the opening a little. Is this going to be a problem?

 

[1029TSG]

No, that wont be an issue since the actuator travel is not long enough to extend the wastegate to that fully opened position. We have sold nearly 1,000 turbine housings in the last 2 1/2 years occasionally making improvements along the way, I feel confident that your wastegate will work flawlessly.

You don't have to worry about the wastegate actuator having enough push or pull to move that arm. I have seen misadjusted actuators that the arm was rubbing up against the inside of the actuator can and after awhile it wore a dent into it. Those things have alot of power to move the arm, and as far as returning the wastegate. Have you tried to pull on the 22lb actuators that Bullseye likes to use?? They are HARD to pull on. You shouldn't have any problems.

lets both do it then, im going down south to a srt4 meet/shootout dyno next weekend, should have my bigger injectors and new boost gauge by then, as well as race gas(im going to buy a barrel of c16, and get a cuttout to bypass the cat

Sounds like a plan Naz

Well after all the talk on this post about the T04b V trim I just placed my order with The Speed Factor for one of these setups. It's going to replace the EVOIII16g that I bought a month ago and havent installed since my car is in storage for the winter. I'm hoping to make atleat 300 whp @ 18 psi anything over that I would be very happy with. If I dont get atleast 300 whp someone is goin to get a t04b where the sun don't shine :laugh: . Anyone one else got one of these installed yet?

 

[btrux06]

ya when i had mine installed i ran 21 lbs and it felt like 400 hp, they did dyno a car at 400 with only 21 lbs too. i ran 14lbs at the begining, held perfectly and it flet like it pulled harder than my big 16g did. ull make 300 at only 16 lbs probably as long as u have all the supporting mods.

David - I picked up my T04b v-trim yesterday. It looks great. Dan was really cool. He gave me a breif tour of the shop, showing be the 5 stages of the casting process. It was very interesting. Anyways, I got a quick question for you. I forgot to buy the 24 month warrantee while I was there.... Can I call you or them on Monday w/ a credit card and buy the warrantee. I totally forgot to do it then, and I just remembered about it this morning. Please let me know.

Also, I have another question. I was asking Dan about using either the 3AN or 4AN feed line. He said either or, but recommended the 4AN. I told him I was haviong problems with the pressure being too high and blowing large amounts of oil past the inner ring in the Mitsu turbos. He said to run these between 35 and 50 PSI. It that at WOT? Also, he recmmended installing a pressure gauge at the turbo to monitor the pressure. But that would do me no good if I had to watch it at WOT.... Can you (or anyone) give me any input on the gauge idea....

Thanks -Paul-

There is an internally gated v-trim with oil feed and drain lines for sale in the classifieds, If anyone was looking for one but couldent afford a brand new one with the oil feed/drain lines.

Dave has stated before that the To4B series Vtrims do not have a 360 thrust bearing, and that it was overkill.

I'd like to know for the record if the TO4Es he sells, like the one I've bought, comes with a 360 thrust bearing, since these thrust bearings are readily available for this series turbo.I never thought to ask this question because I assumed a 360, since that's what is generally required for a turbo designed to withstand high boost levels.

 

[1029TSG]

Factory built Garrett turbos do use 270 degree thrust bearings. Most aftermarket custom built units don't use a 360 degree thrust bearing, its usually a $100 option. I'd rather spend $69-79 on a 24 month warranty.

So, your TO4E does not come with the 360 bearing?

I believe that all the hybrid vendors do offer a 360 thrust bearing as standard--pte, agp and slowboy.

So my AGP RS49 does not have a 360* thrust bearing but a 270 degree?
Oo those AGP RST turbo's use the same Bullseye turbine my RS49 uses?

I believe Ben just uses the Bullseye housing.
I'm pretty sure his CHRAs use a 360 thrust bearing.



My question is about the CHRA Bullseye uses.

 

[sweet97]

My AGP 50 trim does have a Bullseye turbine housing which is very nice, Beefy! I do wonder about the thrust bearing though. I am tempted to get an RS60T for the future as the price is great!

 

[nazthug]

as long as it doesnt fall apart anytime soon, im ok with the 270. and i got the warranty so who cares,

 

[IPT]

Are you sure they are "Standard"? I thought the AGP did the 360 degree thrust as a $100 option. I could be wrong. I do not know about SBR. Some on should call tomorrow and double check.

I do not believe that the 360 thrust is needed. Garrett has been using the 270 for YEARS in almost all of their turbos. The only turbos that are available straight from Garret that have the 360 degree thrust are some T04S 60-1s with the HiFi cover.

 

[joeracer321]

I don't think anyone should be worried if the 270 degree thrust is going to simply fail on them. I believe that if someone is doing a rebuild anyhow, why not install a 360 degree. But I wouldn't start tearing apart a brand new turbo or not buy a turbo due to the standard thrust bearing.

 

[1029TSG]

That may be the only T04E application that uses the 360, there's nothing in the T04B family for sure and Garrett even makes "Big shaft" 270 degree thrust bearings

Dave, My HP wastegate actuator failed!

I took it out and pressure tested it, it didn't budge.

For now I'll have to run it cracked open.

Can you send me out a replacement ASAP?

 

[1029TSG]

Of course, we will send one out right away. You had an H-3?

 

[whitegst97]

I myself got a t04B v-trim, should be arriving in a couple of days. I had a question regarding the water lines. Will in any way the compressor cover bother either the water pipe or the lines coming off of it? All i did was connect the lines together with a silicone hose. Any problems installing this turbo? Thanks
