tuning the buick while i am on vacation.. and find my turbo to build full boost @3500 rpm.. thinking if it would be more valuable to build full boost @ 3,000k instead.. i know they build peak ft lbs @ 2800 but with the turbo i am hoping it will be a little later. i havent redlined this motor yet but what are you guys shifting your nailhead @ ? 5200rpm?? Thanks Paul 66larkgs turbo 401 nailhead
Mine seems to really start falling off at 5k rpms. I wouldn't bother going past 5500rpms, in fact I'd probably shift a little sooner, like 5200rpms.
