Hi people got my car running again today. trying to get it sorted for central day!
When i turn the boost up to 18psi or above its like it blows the spark out! (was mapped at 22psi with new plugs) its has standard Rs turbo plugs in... would cosworth plugs be better suited and what gap size would i use?
Cheers
Danny

 

nowt wrong with rs turbo motorcraft plugs 071's, just make the gap a little smaller.

 

Just out of interest what power did ur ZVH put out at 22psi? Mine is nearly built and excited to know roughly what power it will make.

 

Didn't get mapped on a rolling road, but the tunner said he thought it was around 280bhp
Cheers
