Down pipe diameter
Upgrading to a Precision 7675 turbo over the winter along with a dart 363Boost cranked up to 20-22psi....Will a 3" down pipe to (2) 2 1/2 " pipes dumped at the axle be too small? At the track its open down pipe. Exhaust A/R will be .81 (i think)..I could also get a .96.. description of this turbo says its a 3 5/8" ehaust flange. Other 7675 turbos you can get a 4" exhaust. I dont really want to fabricate a 4" exhaust. Need some recommendations. Thanks. Also was looking at a Comp Turbo...Anyone have any feed back on this brand?
95gt Dart block 363, TEA 205 Heads. 78MM Turdblower Custom cam, All fab work done by me....Moates tuned by me, AODE done up, yep I got overdrive. Drag radials, 327 rear. Next setup to come over winter...lol
