Buschur BR-57 Turbo

[BoostedTT91]

Anyone running a bushchur BR-57? i just put one on my car a few weeks ago and it pulls pretty decent at 20psi but im sure it has alot more power waiting to come out. I was just interested in what people thought of this turbo and how it worked for them. If anyone has any comments, or compressor maps or anything about this turbo, please post. I cant really seem to find anything on this turbo anymore.

I'm guessing it's just like any other 57-trim Garrett hybrid....it doesn't wake up until 25psi, right about when the turbine housing and T31 turbine has reached it's flow limit.

 

[BoostedTT91]

yeah thats what i was told. Would a stock motor with arp headstuds and MLS headgasket be able to hold 25psi?

 

[JusMX141]

The same gasket / stud combination has held 40+psi, so that's not an issue.


I'm completely unfamiliar with the turbo, but Buschur made some serious speed with it a while back:

1991 Eagle Talon Tsi - Project Hugger - The Bottom Line - Turbo Magazine

...although I'm a tad confused....a 1.71 60ft (perfectly normal), and he turns a 10.5 @ 133 using the same turbo and 660cc injectors that other struggle to reach 11's with.

Turbo is not a 57trim. It was named that because it made 570whp on his old dynojet. he never disclosed what the turbo was. my guess is it was 60-1 with stage 5 turbine. but just a guess.

It is a 60-1 turbo. I have been using it for a number of years now on the 92. I recently laid down 432 horse and 400 pds of torque on 20 PSI with Nate from TPG tuning. Its a nice turbo you'll like it.

That 60-1 compressor will reward you immensely if you go above 25psi.

Still not sure why they'd name a turbo with a 60-1 compressor wheel a BR-57, especially when they name their 20G a "BR-20G".

well then that must not be what i have. I bought the turbo of my buddy Zach Jones and he got it from i believe Bean from TurboTrix who was running it on one of his cars. I was told it was a Buschur 57 Trim and its a t3 with a 5 bolt flange. The buschur BR-57 is the only t3 Turbo i have found that buschur was selling. The 5 bolt flange is a real wierd flange that nobody has seen to have seen before and i cant find any gasket that fits it. So im more so trying to find out exactly what turbo this is.

 

[BoostedTT91]

anyone have any ideas what it might be?

post a picture

here are the only pictures i have of the turbo off the car

Acutally measure the wheel. Even with a tape measure. Something . You can't tell anything with internet pictures.

^^ true measure it, but that cover looks like the old school Ts04 housing, but there's so many variations and modified housings out there these days that it could be anything. I've got an older garett catalog with the diameters of all the old wheels (compressor and exhaust) in it and if you can get an accurate measurement then i'm sure there's a few of us on here that can tell you what you have. THat turbine pic is the wrong side for us to judge anything from too.. The other side should be a typical 5 bolt volvo/ford T3 style housing. I use to keep up with the buschur stuff years back and they used that style a lot on the few t3/t4 hybrids that they endorsed/sold

BUt, if it is a 57 trim (which i doubt from that compressor cover) it's a decent turbo... my best to date on my 57 trim on a simple road tune that's not even very agressive recently yielded 431 horses...and it's true that it don't really wake up till 25psi and above...whoooweee i love pulling at about 27psi on mine The 431 was made at 31-32psi 11.5:1 AFR and 20* timing in the 7k RPM range

 

[BoostedTT91]

yeah ill try and get some measurements on it. those pictures are all i really have right now that i could get ahold of while at work. I dont really wanna take the turbo off the car to measure it though

 

[turboglenn]

I dont' blame ya, I wouldn't pull it back off just to see what it is once i had it on and running (at least as long as i was happy with it) but one day if you pull the DP or can get the compressor cover off without removing the turbo, a few simple measurements in those areas would clear up or at least naarow down the possibilities of what is on your car.

Till then i say run that thing and see what she can produce, turn up the wick, add the fuel and burn the rubber!!

7 blades = 60-1 compressor.

The reason he called it the BR-57 was because he ran a 10.57 back in the day with the orange car, that now belongs to Daryl Hudson
