Ken--it may be a good idea next spring--would love to see you---you need to get a fuel pressure guage--autometer are my fav----will answer your PM soon.

My issue with fuel pressure relates to the 15 second stomp in the 1/4 mile. The magenson was designed for street use and I am meeting with the magneson people eye to eye at SEMA Nov 2-6 to discuss the situation. I may need a better aux pump (or just a bigger one in the tank) and a fuel pressure regulator--most likely just a fuel pump and bigger injectors that will give me the optimum fuel after 10-14 seconds of WOT----you and I both want to get over 100 MPH in the 1/4 and my team and I feel fuel delivery after 10 sec. =/- is one of the issues (as is gearing, transmison gear ratios, boost, a/f etc, etc.) They will only talk off the record and tell me what thier fule delivery system was designed for since any change voids their waranty. My warranty was toast before I even installed it because I took the blower off the manifold to have the manifold polished, see pic below. It is no big deal to do this but mag will not waranty anything modified.

I am also meeting with anyone at SEMA who deals with this issue to avoid undo experimentation and cost. If I have to, I will do the experiments but fuel injectors and fuel pumps get expensive if I only use them once for each experiment.

I am also going to contact Ed Potter at LPE after SEMA to see if LPE has done research in this area. They do have the fastest stock (meaning no change in cubic inches) H2 in the US of A.

More in my PM to you later
