[QUOTE="KCTurbos, post: 1546673, member: 13852"] Alright, now we are at the fun part. Taking something that already works great and seeing what we can do to improve upon it. . . Last setup we ran was simply a 73mm comp wheel, rest of the turbo was stock. It was a standard flank mill style compressor wheel that most people use. For this test we dropped down to a 71mm point mill wheel and used a 4” ported cover with anti-surge ring. Stock turbine wheel. Stock HP turbo Pics are attached of this work of art. . . Not huge gains, but we were extremely impressed with the results considering it is a smaller wheel. During the loaded dyno test we gained a peak of 17hp 53tq. It held those power gains throughout the whole power band. . . The smaller 71mm also came on quicker and at 2000rpms it made 75hp and 150tq more. . . During the non-loaded 2000rpms test there was virtually no difference at all. [ATTACH=full]178869[/ATTACH] [ATTACH=full]178870[/ATTACH] [ATTACH=full]178871[/ATTACH] [/QUOTE]
