1. im totally aware of not pulling the car too 8200 too often on stock motor.
2. i do short shift 1-2, the rest i take to 7800-7900, i only take the car to 8000-8200 in fourth.
3. i didnt have a problem going through the 1/4 too when i had 440 hp and 7800k rev. now i have over 500 and my rev was lowered to 7500-7600k
4. im not on 550...im running 524. which in my opion should not be over 130
maybe its just me but 430hp and 128 dont sound right, unless u and your car is a couple hundred pounds lighter than me.

post some vids graphs of the s256 in action....did you ever get any dyno numbers? I remember you guys were playing with the turbine housings trying to get spool down...I remember you said you got 20 Psi @ 4000 RPMS
I originally was going for 700+ WHP so the S256 or 258 would not meet my needs. Once I found I was going to be a daddy I scaled back the HP requirements of the car to maintain decent reliability. The set up is still there in case I want to turn up the wick later on. It is only slightly laggier than the Holset turbo that was on the car previously that made 521 WHP at 28 PSI, and is still only about 300 RPM slower than the 57 trim that was on the car at first. David from Bullseye has just sent me the new .70 A/R V band turbine housing, so I will be switching to that shortly to let the turbo breathe a bit better as it currently has the DSM style .55 housing they offer. I really don't think spool will be effected very much but we will see. Also another think to keep in mind is that I am using a cast manifold for street-ability, using an equal length header would also probably decrease spool time and add a few ponies. I think these turbos are great options over the GT series turbos and will offer many more options then are currently available from the GT line by Garrett.

That could be your problem. You need to shift a little higher on 1-2. Try doing that and you wont bounce of the rev limiter or have to take it to 8+k. Well you have 555whp on you signature and it doesnt add up when you trapped 125 with that much hp. Again, you should be over 130. My car is a full weight car that I drive to work everyday. I trapped 128 only one time and the rest are 125-127 on pump/alky.
That's what we were told too.... not so much. It doesn't spool faster than a T04E 50trim but it does hit harder. It has a hit like no other turbo we have ever felt in that size range.
dude we've offered the S256 in a kit for about a year now. lol
The turbo isn't a bad turbo, it hits like a bat out of hell. We have just been working on getting the spool down. Once we do it will be one hell of a contender.
I haven't heard anything about going BB either.

At least I know now where to go locally for a LICP/DP if I ever decide this turbo is worth it...

[QUOTE=Exciting News;5012727]How about a TS S256? QUOTE]
i think that would be a great product! also if you guys want BBcores for these turbo i think forced inductions are coming out with some soon. also they can build a 'S' version of the turbo that has a smaller (physically) housing to fit into tight spaces.
finally i was told that the advantage of the BW turbos is the ETT. this tech allows a smaller turbo to make more power at the top end, i think by raducing choke thanks to a better breathing hotside. this means a smaller turbo can make the same power as a slightly larger one. this is where the spool advantage comes from.
again this isonly what i have been lead to believe and if anyone can correct me then thanks.

Yeah, I spoke to Forcedinductions guys and they have some BB FI58's already done. They are installing some on some Grand Nationals. I know I spoke to 1 Grand National owner and he is running the FI66-BB and he swapped from a GT67-DBB to it. He says the FI66 spools the same, makes more low end power and boost doesn't drop on the top end.

please tell me which produces more accurate load, uses newer technology, and creates realistic on road situations on the rollers. The Mustang doesn't real low, it reads accurate. The AMS and others read high, as evidence by their unwillingness to let some DTM customers show the large gap. Just because a type of dyno is the "industry standard" doesn't mean it's the most accurate.
The Borg Warner turbos are great for drag racing. The top end is excellent, but a little slower to spool.
For road racing, the Borg Warner S256 seems like a good fit. Anyone have a dyno of the S256?

Just go with a 56mm ETT wheel and ball bearing. That should make them spool nicely.
