Experience with the BR500 turbo?

[natedogg]

Has anyone had experience with Buschur Racing's BR500 turbo? I've been thinking about buying it. According to Eric at Buschur Racing, it spools around 4000-4200 RPM, supports up to 500 whp and bolts up with no modifications required. Its internally gated and costs under $1000 before shipping. Sounds like a hell of a deal. I'd like if it spooled a little faster, but beggars can't be choosers.

From what I've read Buscher is talking down the BR500 and pushing their 20's. The truth is most people get full spool around 3700. I'd like to hear about boost threshold(onset) and transient response(recovery after shifts).

get full spool around 2700

You mean 3700rpm right?

I haven't heard any of that. The guy I talked to at Buschur Racing said they see full spoolup on the BR500 at about 4000 RPM and it supports up to 500 whp. They didn't try to push their 20 on me at all. Not that I would have it anyway considering it supports less HP, spools slower, and costs about $400 more from Buschur. Other shops sell it for less.

My buddy, Darryl Hudson is running a BR580 that is putting out about 575 whp right now and running mid tens. He expects 9's later this season. He's running Buschur's sold hugger orange chassis with his own engine in it. He's had nothing but good things to say about the BR580, but I was trying to get some other opinions from people who have actually run one of these turbos (500 or 580).

there 20g wont spool slower, infact it spools around 3300. plus lag until 4000rpms only sucks maybe if your going 20mph and you drop it in 5th gear and try to take off...

sure there garret hybrids support more horsepower but most people never get beyound 300hp to begin with. we're building up socali eclipse's car around a TD05h 20g, this was mike welsh's old turbo and he was putting down 340hp on pump gas. my point is ride in some cars and feel for what kind of reliability and power you want before you go big.

I've been building and tuning these cars for a little over 3 years now, so I do know a bit. I was just trying to get a feel for these PTE turbos from others who have actually experienced them. I've ridden in a few 20G'd cars and I wasn't all that impressed with the spoolup. They always seemed really laggy to me. I'd stick with my current 16g before I'd ever go to a 20. That's my opinion, so lets leave it at that. I don't want this to turn into an argument about why the 20G is such a great turbo.

My buddy just got a 580 on his street car a few days ago. We're going to tune it pretty soon here, but as of now it starts building boost at about 3200 RPM. He hasn't really opened it up yet, but it gets to 15 psi at about 50% throttle right around 3700 RPM. Once we tune it in (logger, ramchargers MAFT, dyno) I expect it to hit 20+ psi at 4000 RPM, WOT. He's sportin', a built engine, Crower Stage 3 cams, and a FRH cast intake manifold as well as all the other fixins to support such a large turbo.

you know if i rember right the SBR GT-12 supports 500HP and spools up to full boost on mike's car by 3400-3600rpm

I would defently check it out.. it's what i plan on geting some day :/

Keep us posted on how much power that thing makes on pump gas. Maybe even a full review.

Will do.

My 20G hits 16psi at 3200rpm. I outspool our friends big 16g (ported and clipped). Lag isnt the only factor. It also matters what type of power it makes WHILE it is spooling. My 20G makes decent power even while it is spooling up. I am not saying that a 20G could compare to 575whp (hehe)... and sorry to whore your thread...at least you got another view and post out of it

With running this new turbo, is Teflon required to be used on the threads of the oil return fitting at the turbo and the oil feed lines where they bolt up to the turbo and the oil filter assembly? I've been told not to use any sealant of any sort, that the fittings should seal fine.

I'm experiencing a leak at the turbine housing flange where the oil return line hooks up to, but get this, I drained the oil already. How is this possible?
