Do you have any data on the BW S200 range of turbos??

 

Full-Race Geoff, How much power is that 88-75 good for on kill mode? I have talked to you before when I built my last setup about the 91-79 but it was on a long long back order. I ended up with a pte 6262. That turbo is great, good spool, good power.

I am redoing my setup over winter and just want to try something new I guess. Which turbo would you recomend for a 2.0 evo, e85 car, 750-800hp (without running like 50psi ) max revs 9k

Fathouse

 

Geoff thanks for the heads up on the 88-75. I can get that with a T4 flange?

 

i believe he told me you could when i asked about one a couple months back, should be a awsome turbo. Geoff wassup with that K29 my man?

 

Please correct me if I am wrong, but AFAIK, FP's HTA actually IS a BW extended tip wheel, modified and cut down. So, BW doesn't really need "buzz words to counteract HTA-ness"

 

this is interesting. would like to hear more about it

 

I believe they used a BW wheel at one time, but dont anymore.

 

interesting. is that 20psi by 3700rpm with a 2.0l or 2.3l?

 

Thanks for clearing that up.
2.3

 

yes! this turbocharger is ONLY available in T4, but singlescroll .88 or twinscroll .91, 1.00 and 1.10

the main thing with these BW S300SX turbos is that they ALL are identical, simply with different wheels.. they have the same center section, same compressor housing, same turbine housing, etc, its just bigger or smaller wheels to suit the hp level. i can upload some pics to the FTP server tomorrow (its late here and im beat) but the pic i posted previously shows (10) of these




unforutnatley i dont yet know the max potential of the 88-75. My favorite aspect of this turbo is the special turbine wheel design - it uses a blade aero that is very low backpressure for the mechanical energy it generates... there is no other turbine wheel like this that i am aware of, plus you can get it in 1.00 and 1.10 a/r, i think the 1.10 might suit your E85 application nicely. i expect it max out around 710-740hp, similar to the GT4088R, but with quicker spool/response. the power level would ultimately depend on the fuel used, boost level, and of course cyl head/cams/manifolds etc. E85 definintely offers substantial spool/response/power benefit over gasoline.


please get me more info and possibly logs!! i am very interested since very few people run this turbo, and the only other guy im aware of switched to the S300 83-75 and was much happier

unfortunately, not yet.. the performance weve seen from the S300s, however, is very very impressive, its hard to find fault with these units

correct

 

Full-Race Geoff,

sorry for insisting, but could you post the specs of the engine that the dyno chart is from, and the pressure ratio. It looks like it breathes very well indeed and i'm intrested on the displacement and cam setup. The drive setup would be nice to know also, i mean ~600whp on a awd would sound bit high.

I was looking at the comp maps and for 19psi it seems like a lot of air for that pressure ratio.

 

We used to work on a customer car with a full AMS built motor/head on AEM using a S256(old school one tho) and that thing was ridiculous strong from 4200-6500 didnt really care too much for the on-off throttle characteristics of it with the funky external gate on the turbine housing but it really responded well with some 110 octane.

 

Ive used a bunch of the BW stuff before, Im curious as to how the new turbine wheel of the 88-75 compares with the other S300SX series. I know I will buy one at some point, but I was interested to know how it looked side by side, since the dimensions are the same.

 

here is an interesting result from a BW 91-79 *singlescroll* .88 a/r Stock 2JZGTE 1.4Bar boost 98 octane --

its a mostly stock 2JZGTE engine with HKS 264s, BW S300SX 91-79 turbo singlescroll .88 A/R and hks 264 cams, making great power with quick spool, solid in the mid 3000rpms.


i have a 2jz customer with an 83-75 doing a back-to-back test with the high flow 75mm turbine wheel really soon...

sorry i did not answer your post previously, that is my personal car, RB26 stock bottom end, just upgraded oil pump, and fully built head w/ tomei 280s.

**i got really lucky and made it into gran turismo 5

 

very impressive Geoff on that 2jz, those are fairly mild cams and a small hotside for a 2jz making some awesome power
