tr6 plug and colder?(issues)
tr6 plug and colder?(issues) running a stroker cubed ls1 and faithfully been running a tr6 plug with my n/a and nitrous use with no issues. i recently decided to go over the 200hp setting on my plate and decided to go a few steps colder on plugs as well. went to a ngk racing plug which is 3 steps colder than the tr6 standard plug. i went to a r5724-9 plug stock number 7891. well went to track and car did not like the change on n/a of the plug just wanted to snap and pop all thru at any rpm.. so my question would be has anyone run a 250plus shot of nitrous and what plug are most having the best luck with at that level? i do run race fuel 110 and have been for sometime.. thanks

well looking around i run a dart head that calls for a differant ngk plug a fr5, or bkr6e which is 3/4 reach plug.. well the tr6 and colder stuff are .708 reach, so maybe the reach diff. could have made enuff differnance to get the missing out or weak spark im getting? just got lucky maybe running the tr6 before beacuse it was hot enuff the reach did not effect it. thoughts?
