set my boudries? im sorry dave. but i dont have any boundaries. especially when it comes to making a performance product that my name will be on. i am a datto fanatic as are most people on the forum, so im pretty sure that if i like it and its runs good on my car than other people(ie, other datto fans) will most certainly think my product will suit them. i have my full designs already rendered in autodesk inventor(cad 3d) for use with sevral different turbo systems. the only problem i face is which turbo to go with. thanks for the advice but no thanks. ill do it my way.
