<FONT size=4>i have a msd btm box and a paxton sn89 with 6 pounds of boost what should i set the retard at </FONT></P>

vshayes

You can run stock (10*) ignition timing and premium fuel with that low of boost

vfast

about 6 degrees...retard it 10 when starting...set engine timing @ 10 though...use only 93 or higher gas..if it's hot you can add a can of 104 to a full tank but really isn't needed...go 1 step cooler on the plugs and you'll be safe

jadakissnas33

so 1 degree per pound of boost</P>

vfast

yep..that about the rule of thumb but as you go over 10 psi it's like 1.5..coarse this depense on weather and gas

jadakissnas33

ive been runnin it on 2 degrees will ii get more power with 1 degree per pound</P>


</P>

vfast

maybe just a tad....give it a shot...try a can of 104 and 2 degrees retarded..is this a most stock engine?

vfast

I run 15 psi with about 4 degrees retarted...but i use nos booster with o-ringed heads etc..about 550 hp
