br580

[moneybags]

ok people i have a 1990 eclipse gsx with a boost gauge,mbc,unhacked mas,2.5 downpipe,cat,cat back,super afc,255 fuel pump.im waiting for my fmic.im getting a br 580 and i was wondering what size injectors you think i would need and also would i need the injector o-ring kit and a fpr?

 

[larryd]

what is the wheel in the BR580?

 

[Batty200]

I think it is a 56 trim GT series wheel. Not 100% on that one though.

660cc injectors will work fine for the turbo. We have one on our shop car (should be up and running tomorrow). I talked to Tym at Buschur and he said 660's were used on their orange car when testing the turbo. Have you gotten the turbo yet? check out these pics, this turbo is sooooo sweet! You may wanna upgrade mass air flow sensors, the stock one will not be able to keep up with this monster.

hows that internal gate work? any creep? whats the spool like? that turbos freakin nice!! i like.

 

[jzak423]

According to Tym @ Buschur, there was minimal creep and spool time was full in low 4k rpm's. I guess it produced 579 wheel HP at 29 lbs of boost. It also spooled 500 rpm's quicker then the BR-57. This turbo is going to change everything. I'll post performance resualts tomorrow. We're going to tune it then.

 

[moneybags]

jzak423 it sounds like you have it already what all did you get with it?(like gaskets)

 

[jzak423]

It's just the turbo. You'll need a 7cm gasket and the BR-57 install kit. The only issue so far on a first gen is the water pipe has to be bent back slightly. other then that it bolts right on.

Is someone making that turbo for Buschur? From your pics, it looks like the turbine housing even has the bolt holes for the stock heat shields? Do you know if its going to be made available with the compressor outlet elbow already welded on it for a 2G?

Yes, someone else makes the turbo for Buschur, but I'm not at liberty to say who. I can tell you that the company that makes the turbo is well known for making some of the best turbos. As far as a 2G kit, you would have to call them or email them. I'm sure they can make one for you.

 

[brads]

Actually, I know who is making it, I just didnt know if that was public knowledge or not, so I figured I'd ask. It does look nice though. I'm seriously considering swapping out my 50 trim frank hybrid for one. If they have gotten the internal wastegate working good, thats a major plus. It took me a while to get it working good with my turbo, but I would guess that custom turbine housing makes a big difference with respect to that. I need to sell my turbo quick, before people realize just how much better this new one is

Uhm its been mentioned many times on this site that PTE is making the new turbos for Buschur. The housings are just PTE housings, that is why I was asking what wheel is in it.

I think the #s they made are legit but almost false advertising because a normal average joe can not expect to make anything near what they made with that turbo. I just really dont like the fact that they dont tell you anything about the turbo. I think if someone buys a turbo based soley off what the vendor dynoed without knowing anything else is a fool.

ne'er a truer word said. you get props larry me personally, im going with the slowboy gt12. why? cause it spools quick and has great top end. its not a 600 horse turbo but ive realized that my car will never be a 600 horse car. id be more than happy with 400 to the wheels. i can accomplish that quite easily with the gt12 and some tuning. peace all.

 

[jzak423]

I agree also if your looking for a great street turbo, but our car is going to be mainly a track car which will produce big HP. I wouldn't recommend this turbo to anyone with light mods. I'm still not sold on Ball Bearing turbos due to the fact that they haven't proven to last as long as conventional. On a side note we got the car up and running today with the BR580, but as we finished ther was about 3 inches of snow on the ground and no plows in sight (damn I hate winter). I'll have better details on Monday when we tune the car.

Turbos gonna change everything, ha, people always say this shit about ne hybrids. Just a PTE turbo, yay, nothing groundbreaking

 

[jzak423]

Considering the turbo was about $300.00 cheaper then any "mutt" or "hybrid" turbo of equivelant size, plus this turbo bolted up almost as easy as a 16G, I'd say that this turbo would be a nice change. Then again I should wait till Monday after some tuning to hype it up.

 

[brads]

That br580 certainly isnt the first turbo to be sold without the specs attached. But people can usually find this info if they look for it. Take the FP Green and Red for example. The exact specs on those still arent listed on the website. But anyone interested in them could find that info out. Those sort of specs seem to stay secret until just after the first few get sold, then someone looks at what it is, and posts the info.

As for the dyno #s being false advertising because most people cant get that much power out of the turbo, I havent seen ANY turbo vendors yet do advertising for a turbo based on what your average village idiot would get when he bolted the turbo on, and didnt tune the car properly for it. If they have numbers, its either theoretical based off of airflow, or based off of their shop car, or some other highly tuned car. Expecting them to do any differently would be like asking them to shoot themselves in the foot.

Brad,

I agree with you on the dyno information. I should not have used the words "false advertising". I just think its stupid to buy a turbo based soley off what the vendor dynoed it at. Regarding finding out whats in the BR580, Ive looked all around and have yet to find the information.

 

[Batty200]

Well Guys if you look on PTE's Web site and notice that all the GT turbos use a 56trim compressor wheel then you would prob be able to infer with quite a bit of arrurance that the wheel is a 56Trim. Also it would amake sense that the BR500 and the BR580 would be the 56trim with different turbine side and the biggest PTE Mitsu turbo uses a t04 turbine wheel at like TBD a/r with a 76trim Wheel. Aslo the smaller wheels are the T350 69 trim exhaust wheels. I am planning on getting a GT series turbo from PTE but a straight Garret since I have a t3flanged manifold.

yup.

The wheel used in this turbo is definately a bad boy. I spent some time looking over the map, and did a bit of research on it, and I am at this point about 75% sure this is the turbo I am going to run (full Garrett version that is, not the BR580). From an efficiency standpoint, all I can say is WOW. This turbo has the potential to make HUGE pumpgas power with the proper intercooler and tuning. From a power standpoint, look out 60-1. This turbo definately has the potential to outflow the 60-1, can run higher boost much more efficiently, and will spool quite a bit quicker to boot. I was able to find a dyno sheet of a Toyota MR2 with this turbo on it, and it managed 630 Wheel HP without nitrous. (Yes of course built motor, yada yada but that should be a given at this level.) Just for number crunching, the 56 trim has a 61.9mm inducer. Definately seems like an E-ticket ride...hopefully I'll be able to let you all know soon.

Regards,

 

[brads]

I was looking at the 56 trim GT compressor maps too, maybe I was missing something, but it looked to me like at pump gas boost levels, you would be on the wrong side of the surge line till a pretty high RPM, much worse than say with the 50 trim.

I am waiting for this turbo to arrive, I ordered it some time ago, but PTE is lagging right now with all the orders. There was another thread where a guy called and PTE gave him HP numbers for the 50 and 60 trim versions that pretty much matched what Buschur was saying they put out on the 500 and 580.

And as far as Larry's comments....

It says right there on the page that they put down that number at 29 psi, anyone thinking they are running that on their "average Joe" motor is out of their mind. that number is there to display the POTENTIAL the setup has, although I really doubt this turbo is right for most of the people out there looking for a turbo upgrade, since most people talk about getting a 16G or T28, or what have you.

I run 1.7 bar on 91 octane, stock block, a matter of careful tuning

Ok, here are some testing resualts with the BR580.... Keep in mind we haven't been able to tune this car yet (c'mon Ramcharger translater, get here already) so I can't give you first or second gear response times (fuel is just too rich in first and second, car bogs). We were only able to do a quick couple of half throttle runs due to the fact that the car keeps flooding out with fuel. ...

In third gear at 41% throttle, the turbo starts building boost at about 3k rpm's, and hit 20lbs (that's where we got the avc-r set) by 4k rpm's. Keep in mind this is only 41% throttle and the car was pulling very hard. This turbo has no boost creep at all and stays locked at 20lbs like we wanted. We were able to do one jaunt in 2nd gear, but I didn't get a chance to look at the tack due to an incredible amount of "scary tourque steer" (keep in mind this is an AWD car). So far so good, but I can't wait to get this animal tuned right and do some "real testing"

For my daily driver, I'm going to be ordering the 46 or 50 trim version of this turbo (pretty sure the BR580 is a 60-1). So I'll post some resualts in a few weeks when that one arrives.
