tocinoman25 Posted September 23, 2015 Share Posted September 23, 2015 I hope I did this right...I have been busy relocating to Las Vegas etc etc... I finally took the time to do a virtual dyno plot to give you all an idea. Let me know if I did it right? I will be getting a retune on E-85 and 91 crap map Stage 2 was 252awhp and 346 awtq @19.1 psi 3 years ago Power Mods are: Stock Block 90k miles Steamspeed STX 71 Cobb AP v3 via Sti Mikey Tuned on Shell 93 Perrin ELH (ceramic coated) Perrin Turbo inlet Grimmspeed TMIC (thermal coated) Grimmspeed 3 port EBCS Invidia catless DP/Q300 exhaust ID 1000s DW 65C I included the stage 2 dyno sheet Unfortunately the dyno was not working the day of our tune as the shop had relocated and wasnt able to get it up and running. I know there is not alot of data on steamspeed turbos but I am quite impressed with the way it pulls. I will get a built SB eventually and see how the APM tuned blast plates hold up on my 5 speed. I prefer a turbo that will spool a 400-500 rpms earlier and thats why i did start with STX 67 but had fitment issues. Christian @ Steamspeed was kind enough to send me STX 71 while I sent back the 67. Follow me on IG @chefodiycarguy and @chefo.soriano Link to comment Share on other sites More sharing options...
rebourne Posted September 23, 2015 Share Posted September 23, 2015 Are you keeping the 71, or waiting for the 67 to come back? I'm considering the 67+, but I won't be springing for a turbo until around April. Not much info on the 67s like you said, but from what there is, it looks like a really nice balance of top end and quick spool. The 71 v-dyno plot looks like it needs some tuning? Curious if the lack of a torque bump is a tuner (transmission considerations?) decision or the turbo just does that. And the flat spot from 5500-6000 seems like it could be tuned out, since there's more peak hp above that. Oh, and "Dynojet" vs Mustang numbers... Thanks for sharing, and can't wait to see some dyno tuned numbers. pic thread build thread Link to comment Share on other sites More sharing options...
tocinoman25 Posted September 23, 2015 Author Share Posted September 23, 2015 yea i think that 67(+) would be a sweet spot...i may go front mount after all...especially here in the desert...still some tweaking needed for sure I know Mikey is a busy man, I sent logs a week ago...hope to get some real plots soon...I may do an E85 tune soon...waiting on my tuner I emailed Christian as well...hope he gets back to me...Im sure they have been crazy busy. Im still undecided what route to take...ill enjoy this for now but definitely laggy..stage 2 seemed more fun with the torque curve but im sure the 5 speed loves this for now...keep you posted on whats next Follow me on IG @chefodiycarguy and @chefo.soriano Link to comment Share on other sites More sharing options...
need bb Posted September 25, 2015 Share Posted September 25, 2015 Thanks for sharing. On your VD plot the spool seems slow. I would estimate you would reach peak boost closer to 4K RPMs. When did you start the log? Link to comment Share on other sites More sharing options...
tocinoman25 Posted September 25, 2015 Author Share Posted September 25, 2015 Defitinely seems slow...3rd gear pull...start at 2800 rpms i believe...ill try and take more logs down the road but need a revision since i moved no 93 here in vegas...most likely will retune and find a dyno...

need bb Posted September 25, 2015 Share Posted September 25, 2015 That makes more sense. This is my log from my 20G starting at 2K. Full boost is usually around 3.5K. Link to comment Share on other sites More sharing options...
Subabluu Posted May 23, 2017 Share Posted May 23, 2017 Reopening this thread hoping to get insight on the stx71. How well has it held up? What did the final tune look like? Considering buying it for my 05 lgt which just blew the vf40 Link to comment Share on other sites More sharing options...
tocinoman25 Posted May 26, 2017 Author Share Posted May 26, 2017 Reopening this thread hoping to get insight on the stx71. How well has it held up? What did the final tune look like? Considering buying it for my 05 lgt which just blew the vf40 I cant believe this september will be 2 years. Still daily driving on the stx71. It did grow on me and I still liking it...not loving it lol. Im sure the 5 speed loves it as it is still holding up just fine. Been a daddy for just over a year now and its great! Still looking to do an e85 map for sure and get more mileage before dropping in a built sb. If I had to do it again Id probably get a vf52 built from reuben at socal porting or jmp with corn juice and call it a day as it would have the ideal spool and powerband to my liking for a daily. I love that my car is a sleeper though and when the ewg screams the american muscle cars are like whaaaaa....that old man color of a subaru growls too bwahahaha. Updated my build thread and once i get retuned on e85 i will post a plot as i will most likely get etuned with my tuner.

tocinoman25 Posted February 11, 2018 Author Share Posted February 11, 2018 This is just a basemap tune...I feel like she has woken up and had a double shot of espresso. Datalogged on 2/10/2018 75° Elevation 2178 feet E85 with 74% ethanol STi Mikey tuned via cobb ap3 Steamspeed STX 71 (gtx3071r) Excited to post this as its a nice update and will post more after my revisions. Its been a long time coming. Wasnt sure if cobb was going to release a cobb ff kit so i pulled the trigger on an etune. Definitely needs to be leaned out up top. 330whp @5100rpms 340 ftlb @4800rpms My impressions on the steamspeed is that it is laggy but the 5 speed should be happy with this turbo. Maybe i should try out the BCP turbo haha. No knock and she seems to love the corn!
