any setups or dyno would be killer

 

Which S200? S256, S258? S300 series in S200 covers?

 

9:1 GSR motor

This graph is a fewyears old and there are a few diffent turbine housings options available for these now that are better suited for the application.

S256 @ 22 psi:


S256 @ 25 psi:


S256 @ 30 psi:



S256 @ 32 psi:

Im not a turbo pro but i never seen a GSR Make almost 450 ft lbs of tq?

 

PSI2HI do you mind telling us what octane gas was used for each pull

 

110 octane if i remember correctly. This test was done 2.5 years ago.

 

oh ok that 22psi is nice but i plan on using 93 octane so oh well

 

The S259 will make plenty of power @ 19psi.

 

is the s256 the smallest turbo from bullseye? if not what do they make smaller

im looking at something in the 450-500whp max

do they still make ett 50 trims and if so what AR turbine housings are available

it would be on a 20v VW so im only revving to 7500 and am looking for something for the best spool and capable of no more than 500whp

 

some BW 256 results on my motor:

20psi


24psi


above 24psi

 

nice numbers mike what octane ?

 

i beleive we used c16. dont quote me on that cuz it might have been c12. but definately one of the 2.

 

Looks like you have definatly maxed it out at 550. Im sure that mid range dip isnt helping much either.

We have just added the S252 and S247 to our line up. If you are looking for 450whp The S252 or S256 is what i would go with.

i would really like some more info on these turbos

has anyone used one yet?

also how much MAX WHP would each be good for and approx. spool on stock bore and stroke LS

it would actually be on a 20V1.8 VW motor and the closest honda comparison that i have seen is an LS motor until us VW guys change the head and put a cam in and then its comparable to a lsvtec motor
