Does anybody have a compressor map for these twins to show how much they actually flow over stock turbos?

Also what BNR's site & contact details, cos iv changed pc and its not in my favs now...

Rixio

 

I don't have the compressor maps, but I do have the website.

Nice one will give Brian a call

 

edit: on second thought, it'd probably be best to call Brian.

 

Will do...Alabama = AL right? meaning -6 hours to GMT...Time differences bah will have to wait till Monday now, unless somebody else has a comp map...

 

Yes, AL = Alabama, Alabama is -6 GMT. It's 7:15PM here right now, so yeah..you'll have to wait until Monday Afternoon/evening your time to call him.

Of course he does post on here infrequently, maybe you'll get lucky and he'll see the thread this weekend.

 

Yeh, i wish i had posted up yesterday but nm...

I have a S3 pack on my Rz FD atm but its running in and needs another 300 odd miles before mapping...

Just wanted to get a comp map to see the difference in flow over stock turbos before ordering another pack for the other car and race engine...(or getting my hopes up too high)

How many of you run Stage 3 twins & what power are you making & at what boost...

Does anyone know what the atmospheric differences are between UK and the US?

The US always seems to have much higher power figures than compared to over here (No bitching please people its a simple fact)

Iv always used these guys for dyno work http://www.thor-racing.co.uk/Rolling...Tuning-269.asp & they seem to be consistent with figures comparing to other dynapack's across the country...i used to use another tuner with the same dyno but we had a "fallout"

Any help would be great

 

For real power, you need some of that JDM atmosphere.

Barometric pressure is barometric pressure - don't matter a damn what country you are in.

 

The standard/benchmark/God of BNRs is GoodfellaFD3S. He made 421whp on 17PSI, and had a second tune for 19PSI, or more.

Here's his dyno thread. Maybe he'll also be able to drop in with something more useful than what I can provide.

I must say that Bryan Nickell is the 'God' of BNR if anyone is

I've already been talking with Rixio via PM. I doubt you'll get a compressor map from Bryan though.

I think you'll meet your goals of 380 to 400 rwhp sequentially. Main advantage here is very quick spool, with a broad powerband and much cheaper than any single kit out there. Plus, it all bolts up, which makes for an easier (and cheaper) install.

 

But howcome US dyno figures always seem higher then UK figures...???

 

I'm speaking to dynojet or dynapack readings. what dynos do you limey mates use ?

 

http://www.thor-racing.co.uk/Rolling...Tuning-269.asp

 

The can be over 10% difference between Mustang and DynoJet dynamometers, both of which are common here in the US.

 

DynoJet shows higher figures, correct?

 

that's because the UK sucks!





no just kidding. What can I say? Hey man you walked straight into that one lol

 

Nah just yall like to "big" yourselves up :p

Iv been told various figures tbh...some say 10% difference from the US to the UK some say as much as 20%!!! I mean 20% that would mean Rich would be only making 336 atw!!! Which i know is impossible because my stock twins were just under 330 atw...

Just want to get a clear indication of the differences.

For eg. Top gear tested a brand spanking new Mustang on a dyno here and it made a whopping 120hp (iirc) less then Mustang claim it comes out of the factory!

 

it may just be that we have better tuners over here... All tuners are not created equal.

are you sure you're not compairing PS to HP numbers? PS numbers are smaller IIRC

 

by about 0.002 per unit yes!

 

sorry, I meant kw not ps kw is 25% smaller
