im been wondering how to make my turbo spool faster, so i been searching a lot and all i find is junk. some say to port my exhaust inlet some say not to do it. other say so upgrade to bigger exhaust piping....... its confusing..
has anyone here actually tried doing something like that and notice any good results? i ask this because my turbo starts spooling at 3000RPM and i reach full boost (11psi) at around 3,800 rpm. i would like to reach full boost way before that.... i got a generic t3t4 .57 trim and i believe the exhaust side is .63 on my 94 gt, internal waste-gate w/ manual boost controller, 2 1/2" exhaust piping all help is appreciated |

PROBLEM SOLVED!
2 things were wrong with my car: 1) i did a boost leak test and i had a major boost leak at my bov, i guess the o-ring wasnt sealing right. all this time i though the turbo was making a nice spooling sound, but instead it was a lot of air leaking through there lol o-ring was replaced...... 2) i removed the turbo and i checked how the gasket from the manifold matches up with turbo exhaust flange, and it turns out that the turbo had a bunch of metal that needed to be removed in order for the gasket to match... so i ported the opening to match the gasket and also ported my wastegate and polished the exhaust side to remove casting flaws. THE RESULT: I noticed a huge change in responsiveness, now that i reach full boost sooner; not only that but i got a smoother acceleration, i think this was due to the gasket matching on the turbo. And the best part is that i start boosting way sooner than before. By 3000 rpm im already at 5psi. and 11 at 3500 all the way to redline. i also noticed that my boost is more consistent thanks to the porting of the wastegate. no more boost creep at higher RPM's, and the boost spike i had in the mid 3k's is pretty small now... thanks guys for all your help, i hope some one can find some of this info helpful. |
