school me on twin turbos....
 

some of you may remember a post i put up a little bit ago asking about turbos. well i have not yet bought one. i am now thinking about twins but i do not know anything about them or how they work. the truck they would go one is the 1 in my sig. plans changed for me and i sold some toys so the only thing i will be towing is a 30ft toyhauler and my john deere tractors...over all i would like to produce 500+ hp and 1000+ tq. also i want the truck to run 12s in the 1/4. ofcoarse more hp and fast then 12 will be ok...:U: .....

I would say a 35/40 and HTB3 or S475 combo or 62/71 and HTB3 or s475. You could also run a 64/71 but for the power your lookign for you dont need it. Stay away from an S480 I think its going to be way to big for your needs. Honestly you dont really need twins a 62 or 64 single should be fine.

I dont see injectors in your sig. What do you plan to run?

not sure i was gonna wait until i figured out what i was doing for a turbo...

With that much weight, I would definitely look at twins.

Skip the HX35 and hybrid unless you want no more than 500HP. Expect crazy drive pressure with anything bigger than a 150HP injector.

I would run a 62/65 13ss or 14 over a S400. That will provide plenty of air for up to the maximum available fueling for a VP truck. The next step would be a 62/71, but you are going to add lag and not much else.

A S480 is really a waste on a VP truck. They just don't have enough fuel to make the most out of it. And if you were going that route, you would want a 64/71 over the S480.

I really like the he351 over 3b I've been running. Great tow setup with the 200 horse injectors and adrenaline on 2nd setting. I'm going to make another set with a s400 for the other truck to see if it's any better than the 3b. Twins are the only way to go if you tow alot.

I am getting ready to add the s400 to the bottom of mine and the 200hp injectors. a buddy had the same thing in his before ppump and a lot more injector he loved it and it ran clean.

Similar to my Vulcan setup. Cleans up everything I can throw at it.

this sucks i really have no clue what i wanna do......:argh::argh::argh:

That sounds about like the next set I'm going to build myself. 62/14 over an s475. But I need o-rings and head work first, and more money. I love my little towing twins, and they clear up the small sticks well with great spool up and low egt's, but I think a bigger set and more stick would be a lot of fun.

You will definitely want twins for towing, the biggest part is going to be determining which sticks you are going to want to run and building your set from there. Pairing turbos properly takes a bit of research to do, but there are some decent proven combos out there that will work well for what you are looking to do. I honestly think that with the proper exhaust flow, you could get an hx35 or 35/40 hybrid to be comfortable in the 550hp range and still be able to turn the box down and tow. I intend to see just what mine are capable of with some 200's in the near future when I finally get my truck back together.

the HX35 35/40 is one at just under 550HP. Drive pressures are crazy!

If I were building another set for me, I would skip the wastegated housing and go with an external gate. Cost will be about the same, more plumbing, but it will work MUCH better!
