Hey guys,

I have been looking at this system

http://www.summitracing.com/parts/NOS-05151NOS/

I have heard different things from different people weather to have a timing retard or not. Just hoping somebody here will settle the disputes if it is necessary or not, and if it is, how would I go about it. I dont plan on using it alot, just every now and then on the track. I have a 1990 iroc with a 350 with edlebrock shorties if that changes anything..

Thanks.

All it takes is just 1 time to use it wrong...
2 degrees retard for every 50 hp... and a fuel pressure safety switch is also another engine saver... You don't want it on too early 3000 rpm and above or so... do it right and your car will last a long time...

thanks. would you leave the time like that all the time, or just set it that way before you use it like a track day?

 

Some of the popular ignition boxes (MSD, etc...) have an option to adjust / retard timing when a wire is grounded (or when nitrous is active)... Look around for choices and decide what you want from the car... I got an EBL P4 Flash from www.dynamicefi.com Besides tons of tuning capabilities, it can retard the timing for nitrous, it provides an RPM window for nitrous too...

so you cant just adjust your engine timing? is has to be done through ignition add-ons?

 

Sure you can adjust it with a timing light, and some basic tools... just easier with a switch... Do a search here on how to adjust timing...

 

I know how to adjust the timing, just making sure its safe to do things this way.
thanks for your help
