my top turbo is a 62/12 d-tech turbo from diesel power source. how much horsepower can my twins set up hold. the botton is an ht3b.

 

what other mods done to it?

 

Are you running an external wastegate on you HT3B?

 

Yeah, more info needed.

Off the top of my head I would say 600ish, but I could be off on that.

 

My brother has the same twins on his 07 Mega and he is around 600 with a diablo sport on RKL, 90 horse sticks, head studs, and stock fuel system. (we've now added a Raptor 150) We have yet to see it on the dyno since the lift pump. Hope you have better luck with those twins then he has...

 

yes the bottom ht3b is waste gated. and what do you mean i hope u have better luck with those twins than your cousin? do i need head studs. and i have 75 hp nozzles and the stage 2 cp3 pump. with the edge juice stack with the triple dog downloader. .

 

head studs recommended!! yeah what do you mean better that your cousion?? Should we avoid that kit or something?

 

i put the twins on and now my top end performance got worse. i dont know what is goin on. i mean i have plenty of fueling for it. i used to boost about 50 psi on the top end with my single that i had on there. it would throw you back in the seat too. now, with the twins once my over drive kicks in, the truck just fall on its face. i dont know whats goin on.

 

Yeah Im with the rest of them I wouldn't be pushing it without headstuds. Theres so many variables when tunning Twins. Do you have a Crazzy Larry or Pedophile Larry Tune? Whats your EGTS? What kind of Convertor are you running are you on a stock Trans also?

 

no crazy larry, just regular. my egt's are around 1250 to 1300, thats about it. i have a full goerend tranny. billet shafts and converters
