Just got boat runing close to right, still not knowing top speed & already want to put smaller pulley on blower, install shorter drive, & ???

I spent last night wondering about the low boost (6-8 lbs, not quite sure what it was) at the 5600rpm point. Remember this is a 7.9-8.0 compression motor so I could put more boost to it. I do not know what the boost will be at 5800 point, I don't thing I want to spin it any tighter that that.

Jspeed- top of drive is 2" from rub rail. 1.36 gears stock 30" prop. What do you think about a 2" shortie drive??

I called MSD this morning about my box & tech I talked to said that the trigger wire need to be at least 4 -6" away from ANY other wire that has 12v on it. (gauge, power or any other kind of wire) He said if not it will cause problems over 3000 rpms. I asked about the other MSD box I used that worked ok & he said some boxes are more sensitive that others. TECH said I could ship him the box but all they could do was test & see if good, if bad would just throw in trash. Tech did not think it was bad. I wonder if this was problem with my turbo motor??
