Ok, thanks Paul, so much staying on the cheap and fly by pants...the homework has me on the blast path and do it right or don't do it,,,right? The fuel pressure regulator i decided on was NX 15951,Omron Z-15GQ-B7-K clutch momentary switch, MSD 8969 Window switch , and swap out the MSD 6AL with a MSD 6AL-2 pn6530.~ I will update the thread after its all installed. It goes so good now but I see how this should optimize the system and insure more against operating error.. Cheers.!
Ill look at the Mallory does it plug and play with the MSD distributor and blaster 3 coil? http://mallory-ignition.com/hyfire-vi-ignition-system.html
Here are some differences between the MSD 6530 and the Mallory 685 for your consideration. The MSD gives you the choice of using the distributor mechanical advance or locking it out and programming the advance curve with the MSD unit. The MSD unit needs a laptop to program it. It doesn't have a built in RPM window switch so a separate unit is needed. The Mallory unit does not have a programmable advance curve so the distributor mechanical advance is used. The Mallory has a built in RPM window switch. The Mallory unit is programmed by the front panel and does not need a laptop. The Mallory cost less than the MSD. Summit (Free Shipping) has the best price The Mallory can be triggered by your distributor and work with your coil since it is also capacitve discharge. Paul
Have a look at the 685 installation instructions https://www.google.com/url?sa=t&sou...8QFjAA&usg=AFQjCNEN8GEfPIgbQXpwm-VB3FwXfn8hGg and the omron switch schematic a few posts back and how would you recommend wiring it? Also, how would you mount the switch such it interacts with the clutch pedal?
I added the corresponding colors to the three wires that connect to the 685. The orange wire is the Aux RPM limiter for launch control that connects to the Omron clutch switch. The yellow wire is the 685 nitrous timing retard. The violet wire is the 685 Rpm Wiindow Switch. When you get the Omron switch you will have a better idea of what it needs for mounting. It has a threaded panel mount shaft that allows up/down adjustments using the 2 nuts. You will need to make a bracket that mounts the switch so it can contact the upper part of the clutch pedal arm. Some of the Buick clutch pedals had a bracket welded to upper end of the arm that give a good contact surface. I don't know what your pedal assembly looks like. You get to be creative. The switch can be used so that the plunger is in when the clutch pedal is up or it can be set up so the plunger pushed in when the clutch is depressed. It's just a matter of switching the wires that connect to the NC and NO terminals on the switch. Paul
Good Stuff! Will the car have a line lock for the times when you go to the track? What track will you go to?
All parts arrived today! This weekend I'll install and test! NGK plugs, Mallory Hyfire VI, NX fuel pressure regulator, Omron clutch switch. Thanks for the tips fellas. Cheers!
99.9% done. Refueled and rewired and looking great. All but for the mallory hifyre power / ground pig tail was made with female internals so would not connect as the box pigtail is also female. Mallory is sending a new pigtail expected in time to finish this weekend. I had some micro pins and made a pigtail just to temp it together but I will swap that out this weekend, button it all up. Hope theres enough dry pavement to test drive but its looking wet per the forecast. I am stoked! GO HAWKS!!
This thread should move and be sticky at http://www.v8buick.com/forumdisplay.php?55-High-Tech-for-Old-Iron as it doesnt just apply to small block....
