Build In Progress - Any advise

DDGTHS08 · 10-13-2011, 12:43 PM

I am looking for some advise on what I need to do to get to 700hp goal! Below I listed the mods I have in mind, but I'm not sure if these are enough to get me there.

- Snow MPG Max (keep down EGTs and better mileage, not counting on it for the big power)
- H&S EGR Delete (in the closet), H&S Horn, and boost tube
- Twin setup - looking for advise as to which manufacturer you guys suggest
- Air Dog vs Fass (at least a 150gph maybe 165gph)
- ARP studs - will 425s hold up to the 700HP or will I need the 625s
- Fuel? How far will a bag o parts get me? Will I need an upgraded pump and can I get by with one or will I need to go with a duel fueler?

Thanks in advance for any advise and suggestions!

and injector tips.....

bag of parts only get you to about 600rwhp, need injectors while you're in there, 625 studs if using stock gasket, i'm not a fan of twin turbos but call source automotive if you're looking for twins... otherwise get the same performance out of a big single spending half the cash by calling fleece or forced inductions.

700 is a big number, what are your plans for a tranny?

Suncoast is close to home, only 2 hr drive from Mobile. It looks like they have done well with the 48 trannies, and I have seen several peeps on the forum have used them with the 68. I haven't priced it yet but have heard it will be about $4k for the trans. I'd like to keep the 6 speed for the mileage. Has anyone had good luck building the 68 tran?

On the injectors I wanted to go with nozzles - 125HPs? or will they need to be bigger?

I've read twins vs. single on the turbos here on the forum and it seems like it is a matter of personal preference, same power for about the same cost once you get the exhaust manifold, and then you loose the brake or go with an after market. I wanted to go twins for the quick spool up and I will also be towing toys from time to time.

Thanks for the suggestions!

I would install your compound turbos before installing injector nozzles. Twins will tow a lot better and be a more streetable combination than a large single. Looks like you have figured out a good plan of attack. I would also hold off on the water/methanol kit till after you start playing around with your compound setup. Give that 6.7 lots of air and it will reward you!

I would do injectos and like a stage 3 cp3 along with a big single and an air dog and like mentioned above if you want to be able to jump down on it prolly go with 625s

I thought doing the Snow first for the milesage, will I get a little better mileage by getting the twin turbo set up?

Within reason, the more air the better your fuel economy will be weather you are towing or bobtailing.
