around 900 is where ive always been informed that you start having problems with bottom ends. but seriously how much are you looking to spend. this will most likely be a 15k+ build if you do it right and towing with a 800hp mechanical truck is almost hillarious. we cant meter fuel like your common rail buddy.

 

My Dyno runs rite now are 410hp and 980ftibs to the wheels

 

My plan is to use the cam I have now, 150 hp injectors, 4000 govnor springs, twin turbos, ARP main studs, head studs, rod bolts, flywheel and balancer bolts, bore it .020 over, get mahle cast racing pistons, do a Hamilton head with bigger valves, ported, and springs, 20-22 degrees of pump timing with delivery valves, do a gorilla girdle, electric fans. What do u guys recommend for brande of twins?

 

Well... this is gonna be interesting .. towing with a 12v with that level of power ...

you DO realiaze that its not gonna last like 300K @ that power levels ....

and Your gonna be fighting drive train limitations the whole way ... Seriously 500 Is Real fun in a 2wd tow configuration truck ...

800 is sled pullin power ... not street, unless its a street drag or race only truck ... IMO ..

 

Your going to need o rings or fire rings to hold that back likely unless you have. High volume low pressure very efficient set up. Which may be hard to attain. As for brands, every company has a twin kit I'm sure or you can design your own and get someone to make the piping. Bd seems fairly towing friendly.

 

I would most likley go with a Ball bearing turbo .. likley to be more responcive and easier /lighter to spool up ..

 

And I would O-ring ... fre rings have trouble when street usage ...

Unlike pulling . the engine tends to be taken apart freequently .. and or re-torqued the Head freequently ....

 

One of the guys that work and races drag trucks works for source automotive, He has a 700 plus hp daily driver dodge, and he towes a 40 foot fifth wheel with it to.

 

And his Investment has been how much ?

And of course he works @ a shop that is Awesome for performance and testing .. thier Dyno is a beast from what we all hear .... can to wait to punish mine

 

what is the reason for 800hp goal? just for dynos?
