Swine Posted March 6, 2014 Share Posted March 6, 2014 1st graph-original setup 2nd graph- additional mods 3rd graph- additional mods and fresh oem block. Just got back from my tune at Topspeed. Thankfully i have taken all of my past subaru's there to be tuned, so i can do come head to head dyno comparison. -My set up 05 LGT w/100k miles Bnr 18g/perrin tmic/grimmspeed ebcs stock intake with k&n Full exhaust with high flow catted down pipe Dw 65c fuel pump and 850cc injectors -The numbers A little disappointed in the numbers, i was expecting ~320whp and ~350wtq on this dyno. http://i306.photobucket.com/albums/nn263/mcgowsd/7ed9261f.jpg Here you see my 21psi pump gas map and 17psi DD map. Besides the tq just being a bit shy of my expectations, it took longer in my lgt to reach peak tq then in my similar hp wrx and sti, the turbo would be fully spooled, but wouldnt hit peak tq until another 500-750 rpms later(maybe this is a lgt intake manifold thing). On the hp front, the maf was locked @ 4.6v's for about 1k rpms in the upper power band(right where the car holds 300whp), we have a good suspicion that we reached a flow bottle neck at this point limiting me to ~300whp, perhaps the oem inlet? Overall the car is much faster however, i suspect it has gone from a ~102mph stage 2 car to a ~108mph car. Much more power up high, the car no longer has a tq spike and falls on its face higher in the rev range. Anyways, here is a neat comparo for you to digest. My 05 sti and 02 WRX with stock motors and vf-39 on pump gas vs my 18 LGT on pump gas. 21psi for all cars. Enjoy! http://i306.photobucket.com/albums/nn263/mcgowsd/0e56b57b.jpg Edit: RETUNED 12/23/12 after going catless w/AEM intake Went catless and added an intake/retuned 310/340. Ill take it. Planning on a exhaust manifold and inlet next year.http://i306.photobucket.com/albums/nn263/mcgowsd/B3765BC6-4746-411D-99F2-32104A881447-311-0000002CB371DDB0.jpg Retuned 3/3/14. -Added Fast motorsport TMIC -Perrin up pipe -New oem block to replace cracked ringland -Graphs you see are 18 psi safe pump map, 21 psi pump map, 21 psi 97 octane "race gas" map. She drives great. http://i306.photobucket.com/albums/nn263/mcgowsd/8F9A6C16-7481-471D-B50B-57751F539686_zpskaknwnvt.jpg Link to comment Share on other sites More sharing options...
discojon Posted March 31, 2014 Share Posted March 31, 2014 The numbers look good. I have a very similar setup and am currently getting e-tuned by cryo. At this point we are at just under 20 PSI on 93 Pump gas with no knock. I have been curious as to what the potential of this combo is and if the stock MAF tube was going to be restriction at this level. I'll have to check logs to see what my MAF voltage is in that RPM range. I am hoping for 325-350 HP since I have forged pistons I'm less worried about failure of a ringland. If and when I can ever get to a dyno (none within 4 hours of here) I'll post up a map 06 LGT 5EAT BNR18g DW740cc DW65 FMS TMIC Borla Headers Greddy Uppipe Invidia Downpipe Stock axleback for stealth CP pistons King Bearings Link to comment Share on other sites More sharing options...
StuckMic Posted April 1, 2014 Share Posted April 1, 2014 Forged pistons help, but next thing I would worry about is the 5EAT... Link to comment Share on other sites More sharing options...
discojon Posted April 1, 2014 Share Posted April 1, 2014 Its F1 valvebodied. Seems to be holding fine so far. Sent from my SGH-I747 using Tapatalk Link to comment Share on other sites More sharing options...
Swine Posted April 1, 2014 Author Share Posted April 1, 2014 Ive seen the occasional decent result from BNR turbos, but for the most part they dont seem to perform up to par with other 18's. What they do well, atleast for me so far, is bolt in with 0 fitment issues, reliable, and affordable. The BNR 18g performs more like a big 16g with properly matched compressor and turbine housings in my mind. You can see the progression of results through my thread as ive added more and more parts.

BoyceWare Posted December 6, 2014 Share Posted December 6, 2014 How's everything been holding up? Still running strong and realiable since install? Link to comment Share on other sites More sharing options...
Swine Posted December 8, 2014 Author Share Posted December 8, 2014 Yep sitting at 140k miles now. Everything has been solid and I still drive her daily. Link to comment Share on other sites More sharing options...
andyc619 Posted March 23, 2015 Share Posted March 23, 2015 could i use stock injectors with the 16g Link to comment Share on other sites More sharing options...
Rhitter Posted March 23, 2015 Share Posted March 23, 2015 could i use stock injectors with the 16g Yes, injectors and a different TMIC help get the most out of the 16g. But they aren't 100% needed. Anything larger than a 16g though and injectors are basically required. My OBXT build Link to comment Share on other sites More sharing options...
andyc619 Posted March 23, 2015 Share Posted March 23, 2015 ya i was gunnna get the injectors just cant fit it in right now just wanted to make sure its safe thanks man Link to comment Share on other sites More sharing options...
benfrancis Posted March 28, 2015 Share Posted March 28, 2015 TopSpeed switches dynes all the time so who knows if someone takes their car up soon what dyno it'll be. Idk if we've met in the ATL area (got a RBP 4th gen w/ dom 1.5xtr). Good numbers! Link to comment Share on other sites More sharing options...
