Spark plugs gap for big turbo?

[StatusQuo]

As the title says. I searched but only find good info for chipped cars.

What do you guys recommend? Stick with .028 or go smaller? I haven't installed my plugs yet (letting the engine cool) but I have gapped mine to .025

I'll change it if y'all recommend anything else.

Plugs are BKR7E


My setup is on an e50 mix and hp around 320awhp. Spool is at 4k.

What is your spike boost psi

Umm actually the 320hp is what I'm aiming for after this plug and 3bar map install. So I'm guessing 25psi?

I could run what's recommended for K04 maybe?

Do you have a boost psi gauge installed . I ask because some higher psi BT mite blow out the spark and will need to gap the plugs closer or get a modified igniters to keep the spark strong so it doesnt get blown out or miss

Right now I'm peaking 21psi. After the plug and 3bar map install, I'm raising it to 25 psi or whatever gets me to 320awhp.

I'm logging psi with vcds

Imo gaps between .25-.28 are fine with boost up to 28 psi of boost

@ .28

For sure. I went in the middle of your recommendation and gapped to .026.


I'll see how it runs lol

Flashing my new file now. I'm setting it to 24psi and let's see what the virtual dyno says lol

The dsm and Evo guys use it. Consensus concludes it's very accurate.

Uses some physics along with your log data and calculates stuff. Plots AFR and all that. It's compatible with rosstech and Maestro logs


be sure to click the link on PC. Clicking the link on my Android phone takes it to a pretty crappy mobile app. The PC app is where it's at
