My truck is running at 11psi and a wet 75hp shot .....tr6 gapped .035. It was breaking up in the high rpm range at the track but not on the dyno. He told me anything over 8psi he reccomends .028 gap becasue higher boost blows out the spark of the large gap. Any input on what gap you all are running?

 

around 30 thousanths. I dont even gap them. just take them outta the box, make sure they havent been dropped and put them in.

 

I'm running .035 gap. When i had this happen i replaced the spark wire and all went away.

 

.040....never a problem

 

I gap mine at .030

 

TR^'s. .035 and 9-10 psi. 75 shot dry nitrous from time to time. Never cuts out.

 

TR6's gapped .032", 15 psi and an 80 wet shot with w/m.

 

What does the different gapping change? I don't think it is the fuel system .. return system flexfuel with an inline maggie fuel pump and 42lb injectors...

 

Are you still running stock valve springs? If so you might be getting valve float.

 

stock valvetrain and internals.....
