Does anyone have a dyno graph showing what they achieved on BNR twins? I'm looking to do the BNR stage 2 or stage 3 twins, on a street-port running 14lbs or so.



I've seen the estimates but I'm curious if anyone has any real, factual numbers.



Thanks

if you can email viper1308. hes got that same setup and hes got a graph.

Thanks much.

My dyno chart is in the post that is pinned.

It was with the BNR stage 3's running non-seq.

goodfellasfd3 has a dynochart with them

I made 404rwhp @ 1.15bar through a SMIC. Didn't make it to a dyno when running 1.4bar through them (absolutely maxed out on a VMIC) but estimate 440rwhp. Target boost did not arrive until between 5.2 and 5.6k rpm (depending on downpipe) and was held until 8.2k rpm. They started to spool at 2k rpm, but took an age to build full boost, this had the advantage of really good traction - on R tyres I could go WOT in 2nd gear on the road with the tyres just chirping, ideal for picking on quick bikes https://www.nopistons.com/forums/pub...#>/biggrin.gif



Never ran them at any boost level other than the maximum I could get out of them with my car in it's spec at the time so cannot comment on what they are like at 14psi. From memory I dyno'd 355rwhp on wastegate boost when I was having issues.



This was on stage BNR stage 3 turbos a couple of years back.

hopefully i can touch 400 with my stg4
