Very Convincing! Turbo's are hard to choose!

So between the ball bearing gt35r and the BW which has better transient response, partial throttle boost threshold and most importantly the feel of the turbo as it transitions in and out of boost? What are the performance differences of using dual 44mm tial wg or dual mv-s 38mm wg. I have a built 2.5 motor 100mm bore, brian crower 272 cams, upgraded valve train.

these are all excellent questions. to answer your questions
1) better transient response will be found with the 1.06 a/r gt35R. it is a smaller turbo than the BW, so it wont make as much top end power but it will spool faster and will respond faster 2) The tial MVS wg is the only way to go for a subaru, we are very happy these are now available and wouldnt recommend the 44mm unless its a huge turbo drag race application. for time attack and street the MVS is 100% the one to use |

i am basing response purely on the polar moment of inertia. The 35R's turbine is 68mm, quite a bit lower polar moment than the BW 75mm turbine. "feel" is something that is different from every car to every engine and tune. we did extremely well in a full-weight street car at the modified time attack last weekend (2 days ago), using an almost stock 08 sti engine and BW 83-75... keeping up with 2 of the fastest and most develeopd track only subarus (gst and crawford) in a full interior, a/c, p/s, navi, dvd etc 08 sti streetcar is not an easy feat

Thanks for helping make a decision on the turbo Geoff. BTW with the mv-s 38mm what size springs would you use?

Im a huge fan of the 83-75, and after realizing we SHOULD have used the 1.00 a/r on yimisport's STI instead of the too-big-and-laggy 1.10 a/r im even more impressed.. the 1.00 really gives the 35R 1.06 a run for its money... FWIW i run the BWs on my personal cars, and I can get any turbo i want. also, we can special order the 83-75 or 88-75 with a 90-degree-outlet compressor housing that makes charge piping soooo nice in a subie/supra/skyline/240. basically any application with a forward facing turbo and this compressor housing is definitely the way to go. i can post a few pics if you are interested?

-they are singlescroll (go twinscroll or stay stock location IMHO) -they are very thin, and its unlikely it would contain the turbine wheel shrapnel in the event of a burst at temperature -the manifold will have to be custom and will force you to stay with a tial vband housing turbo in the future. you will be unable to change out to anything that isnt compatible with the tial turbine hsg sorry to hear you dont like modified, i can understand why but the guys that work there now are REALLY great guys, they dont BS and dont lie. Some of the guys that no longer work there didnt help the image. here is a great article on twinscroll if you have the time to read http://www.full-race.com/modified-twinscroll/ |

So geoff you would recommend using the BW 83-75 with the 1.00 a/r exaust housing with your new gen 2 rotated kit, i'll be using this with a built block and build heads and cams?

Honestly though, had we used the 1.00 A/R hotside on the BW turbo I'm pretty sure that peak power would have been identical to the the GT35R and boost threshold and the transition to full boost would have been the same or a bit better. The way I see it, the BW 83-75 and the GT35R are nearly identical performers. Given that the BW is rebuildable and cost quite a bit less, it's a veritable bargain. |

So if BW ever develops these their turbos with a bb cartride option it should perform even better? Is the extended tip technology similar to those HTA wheel conversions that are out right now?

Just on a tangent how does the bigger BW variant S300X 91-79 compare to the GT4088R..
What housing would you recommend and which turbo and why?? |

whether a BB center section offers any real performance benefit is still up for debate... the cosworth guys i spoke with seemed to think BB is BS... the BW guys did have a prototype BB chra in development but my understanding is that the miniscule performance gains were not worth the increase in cost, more complex/expensive rebuild procedure, and it may never become a production turbo. who knows what the future holds, but BW is serious about turbos and if they deem the BB chra top be worthwhile, it could possibly reach production.

the .91 a/r is great to start off with and good for up to 28-30 psi but beyond that i think the 1.00 a/r is the one to use. unfortunately the 1.00 a/r for the 79mm turbine wheel may not be available until the end of summer, we are keeping on top of them to get it out soon. all-in-all the 91-79 is a great unit for a responsive 700+whp application thanks!! glad you liked it. im working on another article with them right now for compressor to turbine sizing and matching Last edited by Full-Race Geoff; 06-11-2009 at 09:40 PM. |

I'll post them up and shoot them over to you next week. I'd do it sooner, but I'm actually going to be in Phoenix tomorrow for a mini vacation. I'll give you a call when I get in

Can we get some pictures of the 90 degree compressor on the 83/75 this is the only thing holding me back on getting one of these is fitment.
