i think my factory turbo is on its way out... :mad: so im looking into MPI twins, with the upgraded primary. the motor will be stock for now (the first one i blew will be gettin built) what sorta relsults cant i expect from these twins and what kinda HP/torque can a stock LLY stand up to? other then the motor what else will i need to upgrade?

You might get low to mid 600hp and 1000+ on torque but it will not last long at that level. You will want dual cp3s to take advantage of the turbos and bigger injectors on the built motor.

Hopefully Trent will chime in soon. He has a pretty good running twins truck. :)

my ears were itching for some reason ):h , with the MPI " big twin kit " i am getting 650 hp out of a stock lb7 pump and have ran it 30-35 passes down the strip so far and it hasnt skipped a beat ( stock motor) . if you are planning to build your motor i would skip past the reg twin kits , and skip even further past a standard twin kit with a cheatah/danville , they will not be enough for what you have planned for the truck . the kit i have is the same kit i am recomending . it is also the kit that took Maxed Out Racing into the 10.50 range with dual CP3's , and has ran 11.80 on my truck and my stock lb7 cp3 .
