What plug should I run with a 200-250 shot. Has a dedicated cell with C16 for the Nitrous Daves plate and 91 in the main tank ( probably run 100 ). Will an NGK B8EFS be cold enough? Also what are the jet sizes for a 250 shot on the Nitrous Dave's plate? Thanks for any help.

 

I would start with a #9, you may find an 8 will be o.k. but why risk it at first

 

250HP
N-88.......F@10psi-67.......F@60psi-48

 

Thanks.
