Here are some pics I took of my plugs from my b18b. They are bcpr7es-11. I think I'm going to stop boosting on my pump and fmu setup judging by the way these look. Setup is a t3/t04e .63ar/57 trim with 12:1 fmu, inline pump, fmax intercooler, gsr intank pump, ignition timing set at distributor around 12-13 degrees. I know these pics aren't very clear but its the best I could get with my camera. I'll understand if you guys have a tough time seeing them.

 

Looks like you are pushing it!!! you got an aftermarket fuel pump?

 

Yes, airtex inline and a gsr intank. I had a walbro 255 in the tank but I took it out because I though it might get too much fuel with the fmu and inline already.

 

How much boost are you running?

 

Whoops thats pretty important. Right off the wastegate; 6 psi.

 

I don't think they look that bad actually. Are you seeing any metalic speckels or blistering of the ceramic? If not then chances are you're not seeing enough heat to detonate, but you are running pretty hot to have the plugs that white.

 

they look fine..

 

The plugs don't even have 1k on them yet. I just started boosting last night. Some of the plugs do have small specs or even little indents which I'm believing are signs of detonation. I'm just gonna play it safe. I mean, this is the basic fuel setup used in drag , rev-hard, etc. kits. However I'm sure my turbo is pushing a bit more air in at the same psi than the turbos supplied with those kits. It was fun for last night but I'm gonna play it safe. Hopefully I didn't do too much damage already.
