Attention: TDR Forum Junkies 
I've had my HTT SS 62\13 SS for over a year now and managed to put down 447. 5\983. 5 on the dyno. I'm hoping with the addition of my CFM plus manifold and Spearco intercooler I can crack 500\1100. This tubo has a very impressive whine to it compared to my S300. Even though the HTT is based on a S300 it sounds nothing like one.
Initial spool up is a tad slower but then it really kicks in and spools up fast. The S300 would tend to spike to a high boost level quickly and then settle down some. The HTT turbo boost level just goes up and up when you pour on the fuel. At 30 plus pounds of boost can really hear this thing sucking in the air. If you quickly back off the fuel at high boost levels you hear a very audible whoosh sound but never any barking. $1760 is a lot of money for a turbo but it's worth it. This turbo really benefited from the CFM Plus intake with a noticeable drop in smoke.
