im not smart enough to tell you but that car is so sick

Do you have stock coils? You might just have to adjust the spark plug gap. What plugs are you running and at what gap? You can also post your question in the forced induction section.

stock coils?

I have a gap on 0.6mm

the stock coils can handle stupid amounts of power...they are usually not a issue on builds

with 873.86hp you shouldnt really have a issue with the coils themselves.

have a little different terminology here.

by ignitioners do you mean spark plugs aka

or do you mean coil

the coils will handle the power you are putting down...my guess would be you need to adjust the gap of the plug and possibly look into better spark plugs

Shady is on the right track. The stock coils have supported up to about 1,000 HP according to some of the engine builders over here like Lingenfelter etc... To make that work all they do is tighten up the gap.

yep....there's someone on the board here and local to me running 20 lb's of boost and not blowing out his spark.

I just read that again. You are gapping at 0.6mm.

To convert that to inches for us US citizens we have to divide that number by 25.4.

If that's not a typo then 0.6mm equates to .0236 inches.

That's already a pretty tight gap.

I went back and reread that article. It was Ken Duttweiler that has experimented with the stock coils, and he has found them to support 1,400-1,500 HP with a closer plug gap of .020 of an inch. Probably measured at the flywheel. So I was a little soft on the HP limit, (memory

)

If my math is right you are just a little over .003 away from that as it is.
