So im looking to upgrade my stock turbo to something that I can use in a twins setup later on down the road. Im shooting for 650-700hp with good towing manners cus i will be towing a 33ft go-fast a lot during the summers. I am thinking ether a HTT 62/65/13ss or a 62/71/13ss. What do you guys recommend? Thanks for all the help

I love my HTT 62 65 ss13 very nice to tow with as a single and with my bullseye power twin set up and there S480 with a race cover its unreal that I can pull a 10,000lbs trailer ever week and then hit the drag strip and run 11.8os with a very driveable and tow frindly set up go with the htt 62 65 ss13 you will love it . Good luck

 

I have a just put a 62/71/13 over a 480 on my truck with stock injectors and injection pump to see if it can be done with these and the truck still runs great. The 65 wheel will spool faster but will also have a higher drive pressure when you get to the real high horsepower and high rpm. But for 650-700 you should be fine with the 65 wheel.
