I understand that the 1997 Ram came stock with a HX35W turbo with a 12cm2 turbine housing and a 54mm compressor inducer. The turbo did not seem to kick in till about 1900rpm and pulling my trailer in the Rockeys and Cascades, this was not good.
I just installed an HTT HX35/40W quick spool Hybrid High Performance Turbo, H Charger 60 which is a 12cm2 turbine housing and a 60mm compressor inducer. My turbo now seems to kick in at 2300rpm (+/-). With more air, more fuel, more heat, my egts are up 300 at 900 degrees. My boost also dropped from 21 to 18.
I was hoping that the turbo and boost would start closer to 1600rpm.
Did I goof up or do I need to do something more? I am attempting to get more torque and hp so that I do not have to shift on the grades so early.
I have a K&N filter and a 4" turbo back exhaust, but have done nothing to the pump and no large injectors yet.
If I sound confused, I am. On my 1991, I went from a stock 20cm2 turbine housing and 50mm compressor inducer to an HTT 16cm2 turbine housing and 52mm compressor inducer. Now that truck will run circles around this newer one. No turbo lag, and plenty of git up and go.
Thank you for your advise and hints.
