I upgraded all the fuel relays to the green ones so that shouldn't have been a issue. The FPR hose was still on.

 

True that. She isn't freaking out yet but it's only a matter of time lol. I'll build it as cheap as possible with the best parts possible. I don't want to go through this again at 60k miles.

 

Greens were still failing, blues are the most current relays to use (Jose may have killed a blue one too though). Would be worth pulling the green one out and giving it a shake to see if it rattles.

 

Oops I meant blue. I did the green and then got the complete SSP blue relay package. I will check them though just in case.

 

I have the blue relays sitting in my vehicle box where I keep all my crap... I havent had a single problem with green ones, too scared to replace them as I am not having any problems at all :S

 

Stolen from chkmgnt, hope you don't mind man, but this is exactly what the plugs looked like in 2 and 4. I forgot to take pictures when I was up there. You can see the liner cracks and then slips over the electrode and touches the prong causing misfire.

 

well hope u foind the problem and hope it not wost case senario gl!!

 

I had the same thing happen to my plugs at MSR. Luckily, I got away with new plugs. Basically got a slight misfire then a CEL. Misfire cylinder 2, changed all 4 plugs. Haven't had another issue since.

 

How many miles on the plugs? So far its looking like the stock plugs for the X are not very good at lasting much more than 30k . Hopefully NGK will figure out why these plugs are failing as they aren't on the IXs.

 

That happened to one of my plugs after overboosting before. My car was hating life. I thought I broken something serious.

 

I'm at 48k miles and I've never had an issue. However, I also don't track my car, just daily drive it. YMMV.

 

man that suxs good luck!!!

 

Seems like all the failures are happening to the track guys which makes sense. Change those plugs out more frequently, I don't want to see any more damaged engines!

 

Heat and abuse seem to be the issue, not necessarily miles. I wonder how well those fancy HKS plugs hold up?

 

how much gas was in the car during that run? and it was a right turn when it happened?
