[QUOTE="SCGallo2, post: 16383977, member: 160791"] I purchased a new Whipple 2.9 Gen 4 w/ 3.125” pulley (19psi in good air @ sea level) prior to Black Friday deals, for $2750 - a steal at that price! I installed it mid-January but have been taking it easy due to low outside air temps (lack of traction) and because I would like to get a dyno tune revision when temps get closer to 65-70*F in New Jersey. I stepped up from a Whipple 2.9 Gen 2 with 3.0” pulley (17psi in good air), and despite not going all out, I can confirm that it delivers MORE power, torque, and boost with a larger pulley. I have a Whipple 123mm CAI, CJ twin 65mm throttle body, stock fuel pumps, ID1000s, stock long block, stock exhaust manifolds and cats, Borla axle-backs, stock 3.31 gears, and JDM tune. I also purchased a new 3.0” pulley which I will install with the tune revision, if my fuel system can keep up and my exhaust isn’t too restrictive. Unrelated to the new Whipple install, my clutch (concentric slave cylinder I believe) gave out last week while driving in traffic, and I am currently in work replacing everything in the bellhousing. After some city driving break-in miles, I’ll drive my car up to my Calibrator for a tune revision and dyno and street testing.
