hey guys, many of you probably read my post a while ago about how i switched from an SC50 (31E) where i made 310fwhp@15lbs (full boost by 5,500rpms) to an SC61 (52E) and made 298whp@15lbs (full boost by 6,500rpms), loosing 12hp at the same boost level with a bigger turbo, all because of the horrible spool (comp, leakdown tests were done just to make sure nothing was wrong and turned out good, no exhaust leaks, etc.) also, the 310whp was made in 40 degree weather, no humidity in winter, where as the 298whp was made in 90 degree weather, with 60% humidity.

now to fix the problem....

instead of going from turbo to turbo to find the perfect one, i gave precision a call and talked to them about my predicament, and we came to the conclusion that i would keep the SC61 housing i currently have, but switch over to a complete new turbine wheel and housing, from my SC50 (31E) but with a .48 a/r instead of a .63 a/r like i had at first, which will decrease spool time dramatically. my question is, how well do you think this will work on my application? what kind of numbers should i expect now? and have any of you done it? tuners and builders, please chime in.... i think when everything is done, im gonna run a max boost of 16 or 17lbs, just because i have stock sleeves and i want to run pump gas since its my daily driver.

btw i just ordered ITR cams and valvetrain, so that might help out...hopefully
