Having Horsepower Delimas...

[JaMan]

I'm in the Quest for 500hp with a single in a ETH shouldn't be too hard right! Apparently for me it is. Truck is healthy but can't get by the 468hp mark here's the story. Last year with a new Htb2 62mm turbo and BD4's there was good power and not bad smoke from the honed injectors so I went to some 150 EDM's and picked up quite alot of smoke and higher EGT's so I figure I needed a large single right.

Well I changed exhaust to 5" and no increase then changed turb to a HTB2 Killer 64 and lower the EGT's and gained alittle lag but Dynoed today and no horsepower increase only a Tq decrease because of the more lag. Spooled at later rpms on the dynos were all at the same dyno except for the first with the Honed injectors.

Hope I'm not scattering ya'll but what gives? Had plenty of fueal apparently (Smoke and Egt increase) so I added air and saw no hp increase. Could I have some not efficient Injectors? Gonna try some Jammer 5's 150hp and see if there is some change, need some M4's to try and see if they would make a difference. What gives several people say that 500hp with a Eth and 150hp sticks and the right air and a Drag Comp is feasable right? Fuel pressure isn't a problem and although I've never felt it slip could the OFE be limiting me?

Sorry so long Jared
