twin turboing a ve pump

[93d350]

I would like to twin turbo my 12v. i want to use a hx 35 over a hx55 turbos. my goal is to make as much tow able power out of a ve pump that i can. i was thinking 5x16 injectors and a airdog 150 lift pump. also this thread is just about the motor and turbos plz dont start telling me im going to blow a auto tranny i know and plan a manual swap im just looking for input on twinturboing it. id like over 350rwhp the closer i can to get 450-500 on a ve and still be able to tow id love it. im thinking ill upgrade the rad and use a ps intercooler. i want to build all the piping for the twins my self i have beat some turbo kits for cars so i think im able to do that. Id plan to use a 4 or 5"
exhuast and a 4" pipe from turbo to turbo for exhuast. i was thinking like 3 or 3.5" pipes for the air from turbo to turbo and the biggest air filter i can fit. i think for now ill just used a fliped stock exhuast manifold maybe later ill pick up a bd diesel aftermarket manifold as they say they flow better. well give your input guys and let me know

I wish you luck towing heavy at 350 plus hp. O,,, and your tranny might blow.

Sniff sniff tear 400hp + you better get o-rings and head studs... Your auto will handle a few pulls....I am going on 2 years with mine.

Hey 93! Glad you made it!

Btw everyone, he was told that a VE couldn't handle twins (too hot of EGT's, not enough fuel, etc) on CF....

Poor little fella...

sorry guys the other mods ill have done to the motor that i forgot will be a oringed head,ported head,arp studs,60vavle springs for my exhuast brake,a mild regrind cam from colt.yea i know the stock auto tranny will not take it im thinking a nv4500 swap or a fully built 47rh but im not 100% sure a 47 built will take towing every weekend to the race track.im trying to build a truck i can tow the my race car like its not there and a rig that will have enough power to pull a sled if i and when i hitch up to one.i have always liked go motor mods never has much to make something look good

i also forgot to say ill be running a water/meth injecton setup to help cool it off. i was thinking of putting in a pertty big tank i tow about 200 miles on way to the track. with my gas truck i tow around 75-80 id hope i can do the same with the dodge

ill be towing 6-7k with tools trailer and car if i double pull maybe 10-11k but dont think that will be more then 3 times a year my gf dont race much

You will have better luck for your 400 goal with the 2nd list of mods you posted. Still being able to tow hard using all of that hp will be hard to do.

Snoot, at your power level, and all your updated air flow, can you hold the power for very long??

[93d350]

im hoping with enough air and the right fuel screw setting i can get close to my goal for towing. i guess if it came out to be 300-350 with the fuel screw backed off and i could turn it up to 400ish for truck pulling or playing that would be ok but id like to make as much useable power as i can. im hoping with the right fuel pin and the right star wheel setting i can cut down on alot of the smoke. i really dont want much smoke at all maybe just a puff if i floor it from a stop but i dont want to build any un need heat by "rollin" smoke

[93d350]

also if i means anything to you guys and you didnt find out by my name the truck is a 93 12v ext cab long box d350

What are the specs of the hx55? I can't remember for sure, but I thought it was a little small for a primary. If you need a different turbo checkout http://www.turbosupply.net. An S471 or S475 would work well, part numbers 171701 and 171702 respectively. For your hot pipe I would use schedule 40 3 inch pipe. For your cold pipe I would use 4" exhaust pipe. Check out http://www.sourceautomotive.biz for flanges and oil lines etc. http://www.airflo.com for exhaust piping. http://www.intakehoses.com for intercooler boots,etc. I've got an amsoil dry filter to run on my setup (its a 6080) along with a prefilter http://www.amsoil.com/storefront/eaau.aspx. I got my clutch from, and had my head work and orings done by http://www.powerpartsengineering.com, Terry Shafer is great to deal with and very fair on pricing. John Russin at Buddah Power did my injectors, but people have also had good luck with injectors from Schied, Dynomite Diesel, New Era, etc. All of these links should definitely help, or a least drain your bank account...

Gonna need a bigger radiator and fan probably. At 300rwhp if I actualy make and use that much power for 5 minutes or so it saturates the cooling system and I have to back out of it on a hot day. Another 50rwhp is even more heat load so I would think the cooling system will be even more taxed. You may need that water injection to spray on the radiator to keep it cool! Of course unless you have some really big grades you won't be using but 200hp probably anyways. At 300rwhp and 900ftlb I can pull any grade on the interstates in Kentucky in 5th with 3.54's and grossing 21000lb.

i plan to upgrade the rad and ill be using the water meth to cool off my egt's. iowa aint super hilly but its also not super flat

[Remps]

Have y'all tried water wetter, or radiator relief? It won't work miracles, but it helps a bit..

93, i think what most people are trying to say is that a 1st gen might not be ur best choice for an all out tow rig Dieselpowermag beat-em-up build truck even my truck at the very optomistic level of 300 hp gets hot with no load on hills i can hit 1200 in 2nd gear just getting a heavy load rolling....focus on that tourque number if i want a tow rig that hp numer is the one that gets pricey....not saying at all that it cant be done but u may have hell doing it
