That hx60 is almost 40% larger than that s475..... so if that is true... holset is doing it wrong... It must weigh 10 lbs more than the s475.. Ill post pics and you let me know if you think that the hx60 I have is comparable to the bw..... unless holset makes a larger than hx60...Dont hate micah...=)

As for the text from yesterday; I'd certainly hope that a 3.8L EG with an S475 is quicker than a 2.43 with an HX55
As for the spoolgate idea, tell your fab guy to size things correctly. I'd have used a 44-50mm gate for my crossover. The 60 might bleed pressure to quickly and prove to make tuning quite difficult...just a hint from someone that spent two years calibrating similar situations on diesel engines.
