I ran the H2E on my truck last pull seaon and the boost was great. However, I have decided to retire from the pulling sport. I want to use my H2E again, but don't want all the lag. What all exhaust housing sizes are made (factory and custom sizes)? Can someone e-mail me and tell me how much Adam would charge to re do my H2E if I sent him my good turbo? I am worried that with my heavy fueling, a small exh housing will really drive my egt's on up. Is this right or does the earlier spool up cure most of this? I use my truck mainly now for hauling cattle and my pull tractor (when it gets done) so I can't have too much lag. At the moment, I am running a stock HX40/18cm and the lag is just bearable. Another question. I also have a new HX55 on the shelf in the garage. What can be done to it for lag? Would there be any benefit in having it made into a hybrid as compared to having my H2E made into a hybrid? Hey Adam, if you read this, e-mail me with some prices and info.
