FWIW, I've been pushing my truck up the hills hard for almost 3 years with both spinners. Stock motor with head studs. The engine oil temp concerns me more than the rods.

Least for once theres a realistic hp number. Get the trans done first, lift pump and a good set of tunes. U will be surprised what a stock turbo cant do. Then work towards twins. Just dont get greedy, it happens easily.

I never have wanted to make insane power! 550 as of now is enough once I get there and get bored I'm sure ill upgrade some stuff but for now that's the goal

Okay just like the title says what twins should I run I would like to run a rather small turbo and a rather large turbo for across the rpm range performance.

The goal for this truck is 550 horses. I know there are singles out there capable of this but I am going to be towing a lot and I want to keep those EGT's as cool as possible! I of course plan on other mods but what twin setup is the best for the buck?

My first set of twins was the basic MPI kit....stock LLY turbo with a 74mm atmosphere. It's a nice combo for a stock engine, responsive and a pleasure to drive. The big tune was 545hp uncorrected on a Mustang dyno at 4400' elevation.....that was also an engine friendly tune.

Its actually a really fun truck in the 500-550 range. Ive been past that and into the borrowed time area for awhile now. Thats the not so fun part, noises, and worring whats goin to happen when i pass these cars. Lol

If I go to Danville performance will,someone sit down with me and discuss what all is to be done before this is started I favor face to face communication and I can get a better idea what this build is gonna run me? How much is a twin kit with the s475

475 over stock is the way to go. If you are in Indiana Mark at Danville would be the man to talk to. Buld the trans, installs twins and have Mark tune it and you will be a happy camper.

For a stock motor everyday driver, a 475/stock kit is impossible to beat in my opinion!!

they are just flat fun to drive!

Did you mean "can" do? If a person thinks things thru beforehand and puts the right combo of parts and tuning together, 550 on a stock turbo is doable.

I hope to not get greedy!

I have nothing against running the stock turbo alone but I love the advantages that twins bring! Besides who doesn't love that sound!:drool:

I know where you can find a nice used set of lb7 twins for sale. PM me for details if interested.
