What price are you looking at? Trent quoted me on a very nicely priced S466 with everything. I'm still waiting to see if I have any money after this build. Send him a pm but he is on vacation so give him about a week to get back to you. He also makes twins which are AWESOME!!

I have never used a 466 but I would think it would be. Only difference between a 366 and a 466 is the size of the pedistal. The GT4094 it a T4 turbo and people say it tows good. So I don't see why a 466 wouldn't.

I say a HTT66 or a S366 is closer to a 4094 but they tow better since there waistegated were the 4094 and a S466 is not. Also I mybe wrong but a S466 is biggier then the 4094 Trent can chime in on this.But I would not try towing a 30' with a 4094 I did it with a open deck 16' and a 2500HD 8.1 and the egts were high with a single cp3 going to WV had to use 4th on the big grades and scream it out to 4k ro keep it at 950 area before it was past the 1600.

i wouldnt think a 466 wouldnt be much larger then a 366 other then one is a T3 and the other is a T4. and you could get a .90 A/R again i dont know much about turbos so i dont want someone to go off of what i am saying. just thought since trent was saying a 466 would be good in a twin set up it would perform the same as the 366 did when i had it.

The S464 has a 73mm exducer , so 2 mm bigger than the S300 ,but the inducer is larger i believe , so yes it is going to be a touch laggier than the s300 , But it will support more HP also .

Dale just put a S464 on his LBZ , he has towed with it and said it worked real well . Don't get me wrong if cost didnt need to be considered i would choose the HTT , or S300 , but since a S4 series is almost a G cheaper and has a lot more room to upgrade later ( clear up to a 80mm on the same chassis / pedestal ) then it gets my vote for sure , plus one of these days i will have a twin kit to build off of the S464/466 !

gotcha Trent, thanks for clearing that up for me.
