Towing Twins
Looking for a real quick spool twin turbo set up. I have a hx35 I can use for the lower one but what should I use for the top. I tow heavy a lot 20k most of the time sometimes more. I have a single 63/68 right now it's ok but gets hot pretty quick. I'm running 20* timing have 5x.013 sac injectors 4" exhaust BHAF. Truck has plenty of power it just gets hot too fast. I have to keep backing off when going up hills and I don't want to have to do that. All I'm looking for is 500-550 hp at the rear wheels. I heard a lot of people running the ht3b. I'm kind of leaning toward that but want to know what y'all think.

Towing with 550hp gets hot. Your cooling system while moving 20k at 550hp will absolutly need worked over if you do that often. For a turbo if you want to use the hx. Look at a small s400. Something like a 72/83 with a .90 or 1.0 t4 foot. You need to pull your timing back aswell. Be in the 16-18* range. Towing heavy with lots of timing is not a good recipie at all.

I don't necessarily need 550hp I know theres a sweet spot somewhere for towing. problem I had wad egts got to hot and cracked the head but I was only running a single turbo and it didn't want to light till about 1600-1750. I can back the timing off to. That won't be that much of an issue. I heard some people using an s369 but not sure how that would work. I just know I don't want anything too big for the bottom one
