how much timing with W/M?

[1stgenjake]

How much timing can i run using -20 washer fluid for water meth? i have a M & H timing spacer and DevilsOwn meth coming in a few days...will the combo be too much with a 3/16th bump(about 17* i believe)?

17* should be alright, I wouldn't go much higher then like 20 or 22 with w/m

ok ill have to find out how far the timing spacer moves it...its a mod to the KSB which advances timinf as RPMs go up
