Subject: spark plugs?
Hi Guys,
Ok as my car reaches completion I have started to wonder what kind of spark
plugs should I run. I know this is a minor detail I should know but I have
always run pretty much stock motors in Autox with stock Champion plugs. Now
I am going to run a fairly hot track engine with 11.5 to 1 compression and a
fairly hot high RPM cam. So instead of going through lots of trial and error
the question is. What do you guys that run Tr-6's or Gt-6's run for
sparkplugs??
Thanks

Hi Andy,
Whilst my compression ratio is a tad lower than yours at around 9.75:1,
(hey, c'mon, I have to run my hot street engine on pump gas!),
I do have a fairly hot cam and triple webers etc etc on my Mk.2 Vitesse
engine,
which is basically the same straight six 2-Litre engine as in your GT6+,
I run the following plugs:
1st choice: NGK BP6EV (precious metal)
2nd choice NGK BP6ET (triple)
3rd choice NGK BP6E (grooved)
4th choice NGK BP6ES (copper)
5th choice Champion N9Y (standard), can't recall last time I saw any being
used!
of course, YMMV with higher temperatures etc due to your higher c/r
but personally, I really rate those precious metal plugs, which are special
order from your friendly local automart.
Good luck with your GT6
