blackout

Will I have any detonation running a 75 shot with 14 degrees of timing? I've heard that it will not detonate but then i've heard I should go all the way down to 8 degrees of timing witha 75 shot.

I haven't used the spray yet and want to know what I should set my timing at for the 75 shot... Help me out guys!

You may not but i would back it off like 2-4 degrees and run a 1 shade colder plug... Whats the engine worth to you to find out???

Yeah I guess i'll drop back to 10 degrees and start from there?

It's not worth blowing up, I plan on spraying a 150 shot on it when I get a new fuel pump.

A lot of it depends on your setup. Wet or dry, if wet with what fuel etc

ZEX wet kit,never run below93 octane. I have ported e7 heads, e303 cam, trickflow street upper/lower intake.

I've never spray 75hp, but if I did, I'd have it on 13-14*.

I ran 14 degrees on a 75 shot and had no problems.10 deg would be safe to start with.

I have been told for every 50 shot u use u have to retard your timing by 2 degrees or use racing fuel.

When should I go colder on the plugs? I have a a set of plugs that is two steps colder is that okay to use?

What about a 100 shot and 125 shot? I plan to up the spray really fast, I just haven't run nitrous before and want to progress from the 75 shot up.

For the 75 shot should I lower my timing just to be safe? What shot can I safely go up to without getting the car tuned? Can I just keep changing my timing and be okay?

One step will do fine but you shouldn't really need to go 2 just use one step, and anything 150+ use race fuel..
