Off topic but will you be making ford Taurus sho stuff?
Hmm I also like the 8375 but I am worried it would be too laggy for a daily driven pump gas sub 450whp car. Especially since I'm looking for good response. But I do love the size of the s300 in the engine bay hahahhaha Last edited by WhatTurboLag?; 01-15-2013 at 02:40 PM. |

Interesting the 8070 has the same compressor cover as the 8375? I just like the s300 size compressor cover. My buddies s256 with anti surge cover was a little small. In the end it's just a ricer preference of mine but when it comes down to it ill go with what ever performs best regardless of looks.

Maybe Geoff can be persuated to offer that turbo S200SX-7670 with a FMW compressor wheel? That would keep spool the same and maybe a tiny better then 8070. He also gave the S300 a FMW wheel.... |

Am I to understand that this was without head modifications? What about TGV's?
I got that you did a reversed, ported GrimmSpeed intake manifold. Was this for drag racing? Looks like the full torque wasn't realized till after 5K RPM. Looks great on the top-end, especially if the fuel supply pooped out! |

Also, this was my first trip around the block with the car, very little throttle and almost no boost. Man are these turbos loud! |

What is the best BW turbo to achieve 400 whp with better than stock spool?
I plan on trying to keep it simple and as inexpensive as i can. I want to go efr, ig, ts. Supporting mods will be cosworth pistons, tgv delete, port matched, light port work, dw fp, dw 1200 cc injectors, areomotive fpr, perrin fuel rails, grimmspeed ebc, p&l tb, fr twin scroll exhaust manifold and dp or nameless performance. Might do tomei cams and go one size bigger on the exhaust valve. And i will go sd in the end as well as an e85 map. Gas around here is 92 oct so i dont think 400whp and 400+lbft torque to the ground with better than stock spool is out of the question. I just dont know what efr turbo to get to achieve these goals.

I had a setup made for my buddies 2.0l eclipse, he did a borg warner 57 trim with a custom cut t3 turbine inlet and 4 bolt 2.5 inch outlet to work with the perrin rotated set up (in case I ever need it for my subaru) good to 50 psi and it is slightly bigger than a garret gt30r and will make 400 without being too laggy

The smallest one with a tiny ar. But faster than stock spool is probably not possible. A vf39 is a 6cm (maybe 7cm) hot side. |

That 8375 is insane, you make the same torque as I do at my peak torque rpm, with a freaking td04, although I hit 300ftlbs sooner. Like holy ****. |

May go with the 6258. It spools the best. Im not concerned with hp so much as i am torque. For dd and autox. I supose i would get use to the power i will go with the 6758 but not any bigger. Kind of excited and cant wait to get it done

the other option worth consideration is the EFR 7064 twinscroll iwg, that would be a bit larger but still acheive your targets and goals. both of these are in stock right now, pretty rare for the EFRs agreed the 6258 is a 44lb/min compressor so it could do 400+ as long as the engine can breathe |

My BW s256 7670 hits about 28psi by around 3800RPMs. Power levels on a mustang were approx 400whp/444wtq. I dont have the chart on me right now.

Thanks guys. I'm going to run the 6258 and try to squeeze the most out of it. Then down the road go bigger when i get use to the power. Keep in mind that stock power is enough to get one in trouble. I will get use to 375 - 400 whp before i go for more. I already had an 04 STi running 355whp and 390 lbft to the ground.

I had previously run the S300SX 91-79 .91 AR on the car and was pretty happy with it. I am AMAZED that a 94lb/min turbo is spooling 400-500rpm sooner than the older 82lb/min turbo. On the first trip to the dyno last week I ran my 2007 STi RE090 tires which have good tread but are very dry. The car made 805/636 SAE at 33psi, but I suspected the tires were spinning. Here's a graph of those pulls: And a graph vs the old 91-79- The 91-79 was at 34psi. I decided to try the dyno again yesterday, this time with my drag radials. The results were that the car held traction better to about 6500rpm, then let go hard. The tune and boost were untouched from the previous dyno. Now, SAE numbers are great for bragging rights, but we are at 5400' and our correction factor is pretty high. Here is the uncorrected graph, which in my opinion is still a lot of power for this altitude, at only 33psi ( I want to run 37-38 but need traction). A stage 2 STi only makes 250 uncorrected on this dyno. Someone want to help me embed these? https://www.youtube.com/watch?v=ncnswSPEq4M https://www.youtube.com/watch?v=4u0JHvsxEZc low quality phone vid of the 823 pull https://www.youtube.com/watch?v=CViAUFZeBwk |

Max angle for oil return
Anyone know what the max angle would be on the 6258 prior to issues with oil return or oil going through back seal? Got two of these going on forged ez30r. Image of installation via link
