The other day I was reading an old issue of Turbo magazine and came across an article 502whp @23psi.

I was highly curious that with the BR500 is it possible to make 502whp and is that on pump, +alc, or race fuel?

If anyone knows specifics that would be great,

 

what ever happened to these turbos . . . I'm still wondering? anyone from buschur have anything to say ? I posted this about 8 months ago and no reply

 

At 23psi that alots of power i wonder also was that on pump or alk.

 

That was definitely not on pump gas. It puts out similar numbers to other gt30 setups on pumpgas 385-415. They turned up the wick to get the 500 number.

 

Would anyone mind clarrifing these numbers as you would probably know best or to your best knowledge. I've researched it and done extensive comparisons but would just like the added info from you. at least if it's correct or near.

hp on pump, hp on pump+meth
on a dyno jet or your dyno, specify please

20G-LT > 410pump-?, 460meth -dyno jet
BR50trim> ? ? ? ?
BR3065 > 430pump-dyno jet, 505meth-your dyno
GT35R> ??? pump, 500-600whp varies from anyone

Also, still no info on what happened to the BR440, 500, and 580 ?!?

 

They probably put them out to pasture when they started putting out kits with external wastegates.
