I have already made one turbo grind about 2 1/2 years ago. I have also done another since then, just need to test it out. There is no drop in turbo grind. you must have valve springs. The turbo grind have a lot of lift and area.
the hard part is having to work 7 days a week to pay all the bills and work on the stuff that makes the money to pay them. This cam and intake manifold development had to stop because it was all cash and time out of my own pocket which i can no longer afford. The economy up here in the NW has only been getting worse for the last year or 2. Its pretty bad right now. I had to sell almost everything out of my own car to keep paying the bills because work died down so much. If i had my own car running and driving again, then all of this would pick back up again and get done much faster. Having to rely on other people and using their vehicles for testing works but its not the best way to do things in my opinion.... It is how things have to be done at this point though which is great for those locals here that let me use their time and cars but they do know that they get the best deals on everything as well...
Anyways, I do have plenty of designs to test on the cams and a few little things here and there to change, but that may or may not happen....
