Plug Gap Question?
- Thread starter RARE5.0
- Start date
If it's a 2.3 I'd gap them at .028" and see how that does. That sucker is going to haul some serious mail when he gets it tuned that's for sure. That's what I run on mine and it makes 670hp. But I got full lengths and one of my ported lowers on it as well. Oh and that's my race tune. Almost forgot.
I'm running TR7 iridium plugs and was also having this problem with my Whipple 2.3 (running 19#) at just above 6,000 RPM. I took the plugs out today and regapped them at 0.025" and will be dynoing the car again tomorrow with a race gas / premium blend. I'm also going to make a couple of runs with my 2.7" pulley and am expecting to make around 21# of boost...:beer:
If he's not, he should be running race fuel. That's alot of boost for anything near pump gas. Because of this ditch the iridium and get copper tr6 or tr7. Plugs will foul a lot quicker with race fuel. These plugs work as well or better and are lot cheaper. IMO start with .28 and see how it runs. If it cuts out on the top end, gap down to .26.
