Default twin gt3076 to small for 4.8?
If I run a twin gt3076r turbo, will I be able to get near 700hp with a good tune for my 4.8? Would you guys recommend the gt3076r or gt35r?

going to need more than 60lb injectors if you want to make big power

IMO that turbo is to small but it would spool fast

I've run SD60 injectors with an E50 mixture at 22psi shifting at 6800 with no issue. Isky 218 cam.

58psi made them 73lb. Duty cycle was high 80s. Was enough power to leave 600cc bikes in the dust
