i think i found my new turbo : )

[102487thedude]

i have been doing some research and i finally have decided that i am going to go with the Bullseye S362. which should get me to my mid 400whp mark at 22-23 psi. i will take pictures when i get it.

[IronAudi]

WOOOOOW, better take out your head light to get that monster in there

You are better off going with a true Borg-Warner T4 twinscroll S256-30R, full boost (30psi) at 3700RPMs

[Das General]

The bullseye turbos spool faster than the true BW's. And they offer better warranties.

The 362 should make 400whp fairly easy.

Only because they use exhaust housings with very small a/r's. The T3-S363 comes with a small .70 a/r. It is going to make less power then a true T4 flanged S362 which is equal to a T3/67 turbo.

The BW's just coming out are their newest design while bullseye uses their older version to make their hybrids.

[jackyaudi]

Does that run for $1400 or so?

[102487thedude]

yea but it is well worth the money.

that also means i will get ride of mine for very cheap. who ever is intreasted let me know.

Am thinking of a Turbo like that but next year when I totally fix my car. Turbo is one of the mods I am planning to do. Yes, $1400 will be well worth it

[dougyfresh]

Good deal, Let us know how things go Blake.

[102487thedude]

no problemi will work on it as soon as i get back to the USA.

The BW turbos... how do they compare to GT series turbos?

[mike-2ptzero]

Some of them have extended tip compressor wheels which allow the turbo to be pushed at much higher boost levels to get get that extra flow.

They are oil cooled only and are journal bearing.

I just don't like them being T4 flanges, Now it's the cost of a turbo and a manifold.

[mike-2ptzero]

You can buy T3 to T4 flange so you can keep using the manifold you have now.


This is when having a tube manifold comes in handy, because the flange can just be cut off and a new one welded back on. I am still waiting to get a T4-S366 turbo sent out to me so I can test fit it to make sure it doesn't hit anything. LOL, 82 lbs/min turbo here I come

[dirtybrd]

I was under the impression from talking to Greg about the S265-30R that they were all T4.

But your manifold only cost $300 and you can sell it to recoup some of that cost....

s362 should make good power.

Copy cat.

[dirtybrd]

True. If I get this new job the car will be going on jackstands for a do over and I'll buy a Honda/Acura for a DD. One reason I hope SEM comes out soon, but that may not matter depending on how far I take the car...Mike-2ptzero-ish.
EDITED!!!

[mike-2ptzero]

Copy cat.

LOL, odd aren't you the one trying to be a 1.8T by running a single turbo?

s362 should make good power.

Yes but how much boost is it going to take to make "good" power on a quattro car.

Know any 1.8t's making good power with it? Make sure you double check your info before you answer.

Does anybody make anything that uses variable geometry? I heard amazing things about IHI turbos, specifically the VF39 from the US-spec STi, but the manifold options are very costly and euros don't translate well these days into dollars :(

I'm piecing together a custom build with all the right details and as of now I'm leaning towards the GT28RS or 2871R, but probably the 28rs as I want power earlier. Is it really Garrett or bust for us though?

[mike-2ptzero]

IHI turbos spin the other way.

typhoooooooooooon!

Variable airfoil geometry? Please provide a link. I would like to read up on the turbine and compressor technologies going into automobile turbos. I've done some conceptual design work on variable airfoil geometries for turbines (gas turbine engines). It is used extensively in [gas turbine engine] fans and compressors but mainly from a static (non-rotating) airfoil standpoint.

[AudiA4_20T]

yea but it is well worth the money.

yo man, u wanna trade for the 50 trim and you can just sell that? I should even have some buyers already

[F16HTON]

Twinscroll are T4 flanged. This is the sacrifice you make for 1000 RPMs of quicker spool.

Yea the VTG system in the new porsches.

You mean this? http://www.worldcarfans.com/2051115.002

Thanks. I'll read that article and do some google searching of my own.

Not all BW S-series turbos have extended tip wheels

[AudiA4_20T]

Greg have you seen proven results of 1000rpms quicker spool?

[mike-2ptzero]

There has been very few A4 owners that have ran a twin scroll, me being one of those. He might be going by what other people are seeing on cars like the STI and EVO which are already running big turbo setups with twin scrolls.

[dirtybrd]

I don't really care for a quicker spool, if it gets to early it takes the drivability out of the car.
