Well i am planning on upping the CR and DCR on my setup to roughly 11:1 and 8.5+ dcr just wondering if it wouod be better to run tr6s all the time

 

i run tr-6 and my c/r(s) are the same as u mentioned above

 

when i was running 11:1 cr and 8:9:1 dcr, NA i ran the TR55s nitrous i ran the tr6s, with pretty much the same timing on a 100 shot. towards the end i stuck with the tr6s never seemed to make a difference running NA

 

Ok so no real harm in running the tr6s just for a little proctection against kr.

Skeet and ryan yall are/were both running larger exhaust and l92 heads so you were able to get that hot exhaust out alot more effieciently than i will be.

 

Remember that the TR55 is just a TR5 gapped at .055". The TR6 is factory gapped around .035".

Many people confuse the TR55 as being a half step colder in heat range.

 

Really!? That is news to me, i always thought it was a colder plug...

 

No, the only difference is the factory gap setting. If you're going to be running a .060" gap, go with the TR55. If going for a .040" gap, use a TR5.


The biggest thing that annoys me at work is customers that want "hotter plugs" for their cars. They don't even know what the term means lol.

 

It can't be as bad as going to AutoZone and asking for a range colder then stock. After they get done argueing with you that you don't need it, they then play with the mouse for 2 minutes pretending to look, before saying they don't make one. Better know what to ask for... I run Delco's equlivent to the TR6.

 

If it's not stock you should come in with a part number IMO. Most people who work at parts stores don't know or care about the products they sell, it's just a job.

 

Most of the Zoner's here would have you believe they build Top Fuel dragsters in their off time..
