Richard B. Posted July 18, 2009 Share Posted July 18, 2009 lets say i want the top end equal to the bottom end of the stage 1 tq what would get me there? by a 25% loss i figure at 16 psi we are running close to 320ftlb crank tq. so theoretically 320+crank hp to the 6500 redline would even out the pull. 1st gear pulls hard then its obvious we have more bottom than top as we shift into second while going all out. would a simple d/p and tmic do it? maybe a protune for good measure?

Richard B. Posted July 18, 2009 Author Share Posted July 18, 2009 numbers seem high the legacy was under rated to begin with. no one has done an actual dyno pull to check the real loss of percentage. 25% may be a bit high but 20% is prolly too low. check the dynos. i did a reverse calc with 25% and came up with over 320flt lb but i rounded down...on a stage 1. if one did a 20% calc subaru would have been sued for giving us less than 250hp/tq...that would be stock figures.

lucasmit Posted July 18, 2009 Share Posted July 18, 2009 well at the track I have raced stock cars that are rated slightly over 305crank hp and I have been 3 car lengths ahead at the 1/4 so maybe those guestimates are accurate. Link to comment Share on other sites More sharing options...
GTTuner Posted July 18, 2009 Share Posted July 18, 2009 An SAE net measuement of 320 ft/lbs for stage 1 is too high. I would estimate 280-285 maximum. Stage 2 helps but unfortunately you won't truly open up the top end unless you buy a turbo. Link to comment Share on other sites More sharing options...

E-Tank Posted July 18, 2009 Share Posted July 18, 2009 I am running stage 2 and believe I'm barely making over 300 crank. There is no way a stage 1 tune can make those kind of numbers, and plus WHP is the ONLY number that matters. A lot of us have been on the dyno. I've seen proof that stock hp is a hair over or under 200 and that stage 2 is lucky to make 235. Link to comment Share on other sites More sharing options...

I've seen proof that stock hp is a hair over or under 200 and that stage 2 is lucky to make 235. i am speaking of torque. the reflashed legacy always has more tq than hp. what i was asking was keeping stage 1 tq and extending the top end to be equal. we have all seen proof that 07's were/are hitting 220/220 stock. its on this forum. but that point isnt what i was aiming for. it was making the exact same hp at the top as stage 1 tq is at the bottom. so if that means getting a d/p, tmic, and headers...so be it. if all one needs is a d/p so be it. see what i am getting at? a reverse calc using 25% loss puts 235 at 313chp.

No, Stock turbo can't hold boost in the topend. Even with my stage2 tbe and FMIC I hit 18.5psi @2800rpms and 270whp but I was only holding barely 12 psi at redline. Our stock turbos are just too small for topend. My powerband would drop off after about 5500rpms.

Bbc84 Posted July 18, 2009 Share Posted July 18, 2009 Im stg 2 dynotuned and my peaks are around 275whp and 335wtq ~3000rpms I think. I dont think there is much more the tuner could have done to get me more power on the top end. I know i need a new turbo to get anything more out of the LGT.
